Recombinant interferon alpha 2b for ocular surface squamous neoplasia: An efficient and cost-effective treatment modality in Asian Indian patients
Swathi Kaliki, Swati Singh, Sadiya Iram, Dharani Tripuraneni
Oct 2016, 64(10):702-709
DOI:10.4103/0301-4738.195010  PMID:27905329
Purpose: The purpose was to study the efficacy of interferon alpha 2b (INF α2b) in the treatment of ocular surface squamous neoplasia (OSSN) and analyze its cost-effectiveness in India. Study Design: This was a retrospective study of thirty patients with OSSN treated with topical INF α2b (1 MIU/cc) ± perilesional INF α2b (5 MIU/cc). Results: The tumor involved cornea (n = 9, 30%), conjunctivo-limbal-corneal surface (n = 19, 63%), or bulbar conjunctiva (n = 2, 7%). The mean basal dimension of the tumor was 16 mm. The tumors belonged to Tis (n = 6, 20%) or T3 (n = 24, 80%) based on the American Joint Committee Classification, 7th edition. In the six patients with Tis, three cycles of topical INF α2b were used for immunoprevention. In the remaining 24 patients, INF α2b was advised for immunoreduction, but served as immunotherapy with 100% tumor regression in 22 (92%) cases, and resulted in 95% immunoreduction in 2 (6%) cases. Complete tumor regression by immunotherapy (n = 22) was achieved with a mean number of three topical INF α2b cycles and two perilesional injections. All these 22 patients received three additional topical INF α2b cycles after complete tumor regression. For immunoreduction (n = 2), both patients received six cycles of topical INF α2b which was three perilesional INF α2b injections. The mean total treatment cost per patient with INF α2b was INR 9164 ($US 137). Based on maximum basal diameter of tumor at presentation, the mean total treatment cost per patient with INF α2b was INR 4866 ($US 73) for eyes with microscopic evidence of tumor residue (n = 6), INR 9607 ($US 143) for tumors ≤10 mm (n = 13), and INR 10,985 ($US 164) for tumors >10 mm (n = 11), with two patients needing additional surgical excision for complete tumor control. Conclusion: INF α2b can be used for immunoreduction, immunotherapy, or immunoprevention of OSSN. INF α2b is a cost-effective treatment modality for OSSN at an average total treatment cost of INR 9164 ($US 137) per patient.

The imploding antrum: An unusual case of nontraumatic painless enophthalmos
Debraj Sen, Vijinder Arora, Saurabh Adlakha, Harleen Miglani
Oct 2016, 64(10):786-788
DOI:10.4103/0301-4738.195015  PMID:27905348
The imploding antrum or silent sinus syndrome is a rare phenomenon that presents with spontaneous painless enophthalmos and hypoglobus. It occurs due to ipsilateral maxillary antral atelectasis secondary to asymptomatic obstructive chronic sinus mucosal disease. Ophthalmologists, otorhinolaryngologists, and radiologists must be aware of this entity. This article illustrates the typical presentation in a 17-year-old male with unilateral ptosis and a deep superior sulcus, and characteristic imaging findings of ipsilateral increased orbital volume and depression of the orbital floor, maxillary sinus opacification and atelectasis with retraction of the posterolateral and medial walls, lateralization of the uncinate process, and obstruction of the ostiomeatal unit. This is probably the first time that the syndrome is being reported in such a young person. The pathogenesis, differential diagnosis, and treatment modalities of this entity are also reviewed.

Piyush Jain, Mihir T Kothari, Vaibhav Gode
Oct 2016, 64(10):733-736
DOI:10.4103/0301-4738.195020  PMID:27905334
Aim: The aim of this study was to compare the results of enhanced Brückner test (EBT) performed by a pediatrician and an experienced pediatric ophthalmologist. Subjects and Methods: In this prospective double-masked cohort study, a pediatrician and a pediatric ophthalmologist performed the EBT in a classroom of a school in semi-dark lighting condition using a direct ophthalmoscope. The results of the test were compared using 2 × 2 Bayesian table and kappa statistics. The findings of the pediatric ophthalmologists were considered gold standard. Results: Two hundred and thirty-six eyes of 118 subjects, mean age 6.8 ± 0.5 years (range, 5.4–7.8 years), were examined. The time taken to complete this test was <10 s per subject. The ophthalmologist identified 59 eyes as ametropic (12 hyperopic and 47 myopic eyes) and 177 as emmetropic compared to 61 eyes as ametropic and 175 emmetropic by pediatrician. The prevalence of the test positive was 25.9%. The sensitivity of the pediatrician was 90.2%, specificity was 97.7%, predictive value of the positive test was 93.2%, and predictive value of the negative test was 96.6%. The clinical agreement (kappa) between the pediatric ophthalmologist and the pediatrician was 0.9. Conclusion: The results of the EBT performed by pediatrician were comparable to that of an experienced pediatric ophthalmologist. Opportunistic screening of refractive errors using EBT by a pediatrician can be an important approach in the detection of ametropia in children.

G Jayamadhury, Sudhakar Potti, K Vinaya Kumar, R Madhu Kumar, KC Divyansh Mishra, Srinivasa Rao Nambula
Oct 2016, 64(10):743-746
DOI:10.4103/0301-4738.195012  PMID:27905336
Context: Surgical outcome of retropupillary fixation of iris claw lens. Aims: To evaluate the various indications, intra and post-operative complications, and visual outcome of retropupillary fixation of iris claw lens in aphakic eyes. Settings and Design: The study design is a retrospective study at a tertiary eye care center. Methods: Review of medical records of 61 aphakic eyes of 61 patients, who were rehabilitated with retropupillary fixation of an iris claw lens, with a follow-up duration of at least 1 year. Statistical Analysis Used: Data analysis was performed using paired t-test and Chi-square test. Results: Mean preoperative uncorrected visual acuity was 1.66 ± 0.3 LogMAR and postoperative acuity at 1 year was 0.53 ± 0.5 LogMAR (P = 0.00001). Preoperative distant best-corrected visual acuity was 0.30 ± 0.48 LogMAR and postoperative acuity at 1 year was 0.27 ± 0.46 LogMAR (P = 0.07). Mean preoperative astigmatism was 1.43 ± 1.94 D and postoperatively was 1.85 ± 2.16 D (P = 0.0127). Mean endothelial cell count was 2353.52 ± 614 cells/mm2 preoperatively which decreased to 2200 ± 728 cells/mm2 at 1 year follow-up (P = 0.006). There was no significant difference in central macular thickness and intraocular pressure pre and post-surgery. Complications included ovalization of pupil in 9.83%, hypotony in 1.63%, toxic anterior segment syndrome in 1.63%, cystoid macular edema in 11.47%, epiretinal membrane in 3.27%, and iris atrophy in 6.55%. Conclusion: Iris claw is a safe and an effective method of rehabilitating aphakic eyes.

Jehard Hashoul, Waleed Saliba, Irina Bloch, Haneen Jabaly-Habib
Oct 2016, 64(10):767-769
DOI:10.4103/0301-4738.195003  PMID:27905341
Creutzfeldt–Jakob disease (CJD) is a rare neurodegenerative disorder characterized by rapidly progressing dementia, general neurologic deterioration, and death. When the leading symptoms are visual disturbances, it is termed as the Heidenhain variant of CJD (HvCJD). CJD was reported following prion-contaminated pericardium transplants but never after bovine bioprosthetic cardiac valve. In this case report, we describe HvCJD in a patient who had a bovine bioprosthetic cardiac valve implant. An 82-year-old-woman was referred to neuro-ophthalmology clinic for unexplained visual loss that started 1 month previously. Medical history included aortic valve replacement with bovine bioprosthetic valve. On examination, best-corrected visual acuity was 20/120 in the right eye and 20/200 in the left eye; otherwise, the eye examination was normal. Humphrey visual fields revealed complete right homonymous hemianopsia. Magnetic resonance imaging (MRI) demonstrated nonspecific white matter changes. A week later, she was hospitalized due to memory impairment; repeated MRI and total body computed tomography scan showed no significant findings. Electroencephalography recordings and extremely elevated cerebrospinal fluid tau protein were compatible with CJD. The patient died 3 weeks later; autopsy was not performed. The patient had HvCJD. Ophthalmologists being first to see these patients should be aware of this diagnosis. Contaminated bovine bioprosthetic valve might be another source for prion disease. Further research is required to establish this issue.

Paradee Kunavisarut, Pimploy Chavengsaksongkram, Aniki Rothova, Kessara Pathanapitoon
Oct 2016, 64(10):710-714
DOI:10.4103/0301-4738.195018  PMID:27905330
Purpose: The purpose of this study was to compare screening methods for the early detection of maculopathy in patients treated with chloroquine (CQ) or hydroxychloroquine (HCQ) and to identify the risk factors for the development of toxic maculopathy. Methods: We performed a prospective study of all 217 patients taking CQ and/or HCQ and seen in our center between July 2011 and December 2013. All subjects underwent a complete ocular examination, as well as spectral domain optical coherence tomography (SD-OCT), fundus autofluorescence (FAF), and 10-2 Humphrey visual field (10-2 HVF). Results: The median age of patients was 51 years, median CQ/HCQ duration was 40 months, and median cumulative dose was 180 g. The prevalence of at least two abnormal tests was 7.4% (16/217). SD-OCT had the highest sensitivity, specificity, predictive values and accuracy while 10-2 HVF showed in 30% of nonreliable results and had the lowest specificity and positive predictive value. In multivariate analysis, an age of older than 60 years (P = 0.002), CQ duration of more than 5 years (P < 0.001), and CQ dose more than 3 mg/kg/day (P = 0.005) were associated with toxicity. Conclusions: In patients with unreliable outcomes of 10-2 HVF testing, SD-OCT in combination with FAF might represent a suitable alternative screening tool for toxic maculopathy.

Nikhil Shreeram Choudhari, Vanita Pathak-Ray, Sushmita Kaushik, Prateep Vyas, Ronnie George
Oct 2016, 64(10):715-721
DOI:10.4103/0301-4738.195004  PMID:27905331
Purpose: The aim of this study is to explore and compare the prevailing practice patterns in the diagnosis and management of glaucoma among subspecialists and general ophthalmologists in India. Materials and Methods: This is an interactive audience response system (ARS) based poll of ophthalmologists attending the annual conference of the Glaucoma Society of India in 2013. Results: The information was obtained from 379 ophthalmologists (146 glaucoma specialists, 54 nonglaucoma subspecialists, and 179 general ophthalmologists). The majority of polled ophthalmologists (236; 62%) had 10 or more years of experience in ophthalmology. The glaucoma specialists differed from nonglaucomatologists in their preference for Goldmann applanation tonometer (P < 0.01), four-mirror gonioscope (P < 0.01), Humphrey perimeter (P < 0.01), laser peripheral iridotomy in primary angle closure disease (P = 0.03), postiridotomy gonioscopy (P < 0.01), and usage of antifibrotic agents during filtering surgery (P < 0.01). Optical coherence tomography was the most preferred imaging modality and was utilized more often by the subspecialists than general ophthalmologists. The ophthalmologists also differed in their choice of antiglaucoma medications. More glaucoma specialists were performing surgery on children with congenital glaucoma (P < 0.01), implanting glaucoma drainage devices (P < 0.01), and using scientific journals to upgrade knowledge (P = 0.03) than the other ophthalmologists. Conclusions: This poll is the first of its kind in India, in its usage of the ARS, and in comparing the practice patterns of care for glaucoma among subspecialists and general ophthalmologists. It has revealed substantial diversity in a few areas among those who did and did not receive specialty training in glaucoma.

Publication rates from the All India Ophthalmic Conference 2010 compared to 2000: Are we improving?
R Kumaragurupari, Sabyasachi Sengupta, Sahil Bhandari
Oct 2016, 64(10):722-726
DOI:10.4103/0301-4738.195007  PMID:27905332
Purpose: To determine the publication rates of free papers and posters presented at the All India Ophthalmic Conference (AIOC) 2010 in peer-reviewed journals up to December 2015 and compare this with publication rates from AIOC2000 published previously. Methods: A thorough literature search was conducted using PubMed, Google Scholar, and the general Google search engine by two independent investigators. The title of the paper, keywords and author names were used to “match” the AIOC free-paper with the published paper. In addition, the “purpose,” “methods,” and “outcome measures” between the two were studied to determine the “match.” Results: A total of 58 out of 394 free-papers (14.7%) from AIOC2010 were published till December 2015 compared to 16.5% from AIOC2000. Out of these, 52 (90%) were published in PubMed indexed journals. Maximum publications were seen in pediatric ophthalmology (50%) followed by glaucoma (24.4%) and cornea (23.8%). Fifteen out of 272 posters (5.5%) were published; orbit/oculoplastics had the highest poster publications (13%). Excluding papers in nonindexed journals and those by authors with international affiliations, the publication rate was approximately 12%. Conclusion: The publication rate of free papers from AIOC2010 has marginally reduced compared to AIOC2000. Various causes for this such as lack of adequate training, motivation, and lack of incentives for research in the Indian scenario have been explored, and measures to improve this paradigm have been discussed. It will be prudent to repeat this exercise every decade to compare publication rates between periodic AIOC, stimulate young minds for quality research and educate policy makers toward the need for developing dedicated research departments across the country.

Manpreet Singh, Natasha Gautam, Adit Gupta, Manpreet Kaur
Oct 2016, 64(10):778-780
DOI:10.4103/0301-4738.195013  PMID:27905345
A 2-year-old boy presented with a recurrent strawberry-like reddish mass arising from the left caruncular region for 8 months. An incisional biopsy was performed elsewhere 2 months earlier, followed by an increase in size of mass, significant epiphora, and intermittent bleeding. On examination, exuberant exophytic gelatinous mass with multifocal origin was observed arising from inferior forniceal conjunctiva and caruncle. Clinical differential of multifocal conjunctival papilloma was kept, and topical interferon alfa-2b (INFα-2b) was started. No clinical reduction in mass or symptomatology was observed over 6 weeks. Excision biopsy with cryotherapy and subconjunctival injection of INFα-2b was performed over all foci. Conjunctival papilloma was confirmed on histopathology, and topical INFα-2b was continued in postoperative period for 3 months. At 14 months of follow-up, no recurrence, epiphora, or bleeding was noticed. We advocate a possible role of local INF therapy in managing and preventing recurrences of conjunctival papillomatosis.

Ozlem Ural, Mehmet Cem Mocan, Anıl Dolgun, Ugur Erdener
Oct 2016, 64(10):752-755
DOI:10.4103/0301-4738.195016  PMID:27905338
Aims: To evaluate the utility of margin-reflex distance (MRD) as an alternative to levator function (LF) in choosing the appropriate surgical procedure for congenital blepharoptosis. Settings and Design: This was a retrospective, observational study. Subjects and Methods: Records of patients with simple (dystrophic) congenital ptosis who were operated and followed for ≥6 months postoperatively and whose outcomes were deemed as successful were evaluated in the study. Success was defined as a MRD at the last postoperative visit of ≥3 mm. In all cases, levator resection was performed when LF was >4 mm and frontalis suspension when LF was ≤4 mm. Statistical Analysis Used: For statistical evaluations, LF was accepted as the gold standard parameter for deciding on the surgical intervention, and the optimum cutoff point for initial MRD was determined as the point at which sensitivity and specificity was highest at the receiving operating curve for the selection of surgical procedure. Results: Of one hundred and three eyes of ninety patients (44 female/46 male), levator resection was used in 44.7% and frontalis suspension in 55.3%. When the optimum cutoff point for MRD was determined as 0.5 mm, the sensitivity was 71%, specificity was 86%, and the area under the curve that represented the discriminative power of this parameter was found to be 0.826. Conclusion: The MRD at the cutoff point of 0.5 mm may be used as an alternative to LF to determine the type of surgical intervention in patients with congenital blepharoptosis whose LF cannot be reliably obtained in clinical evaluations.

Choroidal thickness evaluation of healthy eyes, central serous chorioretinopathy, and fellow eyes using spectral domain optical coherence tomography in Indian population
Supriya Arora, Richa Pyare, Preethi Sridharan, Tarun Arora, Meenakshi Thakar, Basudeb Ghosh
Oct 2016, 64(10):747-751
DOI:10.4103/0301-4738.194999  PMID:27905337
Aim: The purpose of this study is to establish a normative database of subfoveal choroidal thickness (CT) in healthy young Indians using spectral domain optical coherence tomography (SD OCT). Evaluation and comparison of CT of central serous chorioretinopathy (CSC) and fellow eyes were also performed. Materials and Methods: This was a prospective, cross-sectional, and observational study. It included 112 normal eyes of 112 healthy volunteers who had no evidence of ocular or systemic disease, 84 CSC eyes with acute, treatment-naïve CSC, and 69 fellow eyes with no evidence of neurosensory detachment or pigment epithelium detachment on SD OCT. Complete history, examination, and SD OCT were performed in all eyes. Results: The mean age of 81 patients (84 eyes) with CSC was 35.04 ± 8.86 years, 69 fellow eyes was 34.61 ± 8.71 years, and 112 healthy volunteers (112 eyes) was 33.16 ± 9.4 years (P < 0.05). The mean subfoveal CT of CSC eyes was 429 ± 74.18 μ, fellow eyes was 360 ± 57.99 μ, and normal eyes was 301.80 ± 46.59 μ (P < 0.001). Conclusion: CT varies not only with age, axial length, and refractive error but also with races. Therefore, it is important to establish a normative database in a particular population before carrying out further research in diseased states. CT in CSC eyes is significantly thicker than fellow eyes, and CT of fellow eyes is significantly thicker than normal eyes. This reinforces the fact that choroidal permeability is increased in both eyes of patients with CSC.

Effect of prophylactic intraocular pressure-lowering medication (brinzolamide) on intraocular pressure after ranibizumab intravitreal injection: A case–control study
Shuang Song, Xiao-bing Yu, Hong Dai
Oct 2016, 64(10):762-766
DOI:10.4103/0301-4738.195006  PMID:27905340
Purpose: To observe the effect of prophylactic intraocular pressure (IOP)-lowering medication (brinzolamide) on IOP after ranibizumab intravitreal injections (IVIs). Materials and Methods: This prospective case–control study included 352 eyes from 352 patients (1 eye per patient) who were treated with ranibizumab intravitreal injection and divided randomly into two groups. Two hundred and three patients in control group only received the ranibizumab IVI, but 149 patients in case group received one drop of prophylactic intraocular brinzolamide preinjection. The IOP was measured by noncontact tonometer before injection, at 10, 30, 120 min and 1 day after injection in a sitting position. Results: The mean IOP measured before injection, at 10, 30, 120 min and 1 day after injection individually were 15.79 ± 2.21 mmHg, 19.33 ± 4.86 mmHg, 16.64 ± 2.93 mmHg, 16.17 ± 3.13 mmHg, and 15.07 ± 2.55 mmHg in case group and were 15.82 ± 2.57 mmHg, 21.34 ± 5.88 mmHg, 18.17 ± 4.06 mmHg, 17.59 ± 4.42 mmHg, and15.48 ± 2.92 mmHg in control group. Comparing two groups, the mean increase on IOP was statistically significant at 10, 30, 120 min postinjection (P < 0.05). Conclusions: IVI of ranibizumab causes a considerable short-term transient rise on IOP in most patients. The effect of prophylactic IOP-lowering medication on IOP after IVIs can be statistically significant from 10 min to 2 h after IVIs.

Ji-Hye Park, Chungkwon Yoo, Jong-Suk Song, Shan C Lin, Yong Yeon Kim
Oct 2016, 64(10):727-732
DOI:10.4103/0301-4738.195000  PMID:27905333
Purpose: To investigate the effect of phacoemulsification on intraocular pressure (IOP) in different recumbent body postures including supine and lateral decubitus (LD) positions. Materials and Methods: This prospective, observational study included patients who had no glaucoma and who had planned to undergo phacoemulsification and intraocular lens implantation in one eye. Before and 1 month after cataract surgery, IOP was measured in both eyes using the Tono-Pen AVIA. We measured IOP in the sitting, supine, and LD (with the operated eye placed on the lower side) positions. IOP was measured 10 min after assuming each position in a randomized sequence. The Wilcoxon signed-rank test was used to compare the IOP changes before and 1 month after phacoemulsification in all postures. Results: Twenty-nine patients participated in this study. Postoperative IOP was lower than the preoperative IOP when measured by Goldmann applanation tonometry in the sitting position (13.8 ± 1.9 mmHg vs. 12.6 ± 2.1 mmHg, P = 0.007). The postoperative IOP was lower than the preoperative IOP for the supine and LD positions. The average IOP reduction of the operated eye was 0.6 mmHg, 1.7 mmHg, and 3.0 mmHg in the sitting, supine, and LD positions, respectively (sitting vs. supine, P = 0.048; sitting vs. LD, P = 0.001; supine vs. LD, P = 0.028). In the nonoperated eye, IOP did not change significantly after surgery (all P > 0.05). Conclusions: Cataract surgery lowered IOP in the sitting position as well as in the supine and LD positions. Such postoperative IOP reductions were greater in the recumbent positions than in the sitting position.

Dhanashree Ratra, Dhileesh P Chandrasekharan, P Aruldas, Vineet Ratra
Oct 2016, 64(10):775-777
DOI:10.4103/0301-4738.195009  PMID:27905344
We report a unique case of a patient with retinitis pigmentosa (RP) phenotype in one eye and pigmented paravenous retinochoroidal atrophy (PPRCA) phenotype in the other eye. We describe in detail the symptoms, clinical findings, and investigations done for a 32-year-old Indian woman. This patient had phenotypical picture resembling typical RP in the right eye, with characteristic symptoms of night blindness and constricted field of vision and a nonrecordable electroretinogram (ERG). The left eye of the same patient revealed typical PPRCA phenotype, with no night blindness, normal field, and normal ERG. RP and PPRCA phenotypes are part of the same spectrum of genetic disorder. However, it is rare to see them coexist in the same patient.

The TP53 is important in functions of cell cycle control, apoptosis, and maintenance of DNA integrity. Studies on the association between p53 codon 72 polymorphism and primary open-angle glaucoma (POAG) risk have yielded conflicting results. Published literature from PubMed and Web of Science databases was retrieved. All studies evaluating the association between p53 codon 72 polymorphisms and POAG were included. Pooled odds ratio (OR) and 95% confidence interval (CI) were calculated. Eleven separate studies including 2541 cases and 1844 controls were pooled in the meta-analysis. We did not detect a significant association between POAG risk and p53 codon 72 polymorphism overall population except allele genetic model (C vs. G: OR = 0.961, 95% CI = 0.961–0.820, P = 0.622). In the stratified analysis for Asians and Caucasians, there was an association between p53 codon 72 polymorphism and POAG. In the dominant model in the overall population and by ethnicity subgroups, the highest elevated POAG risk was presented. In summary, these results indicate that p53 codon 72 polymorphism is likely an important genetic factor contributing to susceptibility of POAG. However, more case–controls studies based on larger sample size and stratified by ethnicity are suggested to further clarify the relationship between p53 codon 72 polymorphism and POAG.

DOI:10.4103/0301-4738.195011  PMID:27905335
Background: To determine the incidence of early postoperative complications and associated factors after primary trabeculectomy in Thai glaucoma patients. Design: This was a retrospective observational study performed in Chiang Mai University Hospital. Participants: One hundred and eighteen glaucoma patients participated in the study. Methods: All glaucoma patients underwent primary trabeculectomy with mitomycin C (MMC) using fornix-based conjunctival flap technique between December 2011 and May 2013. Surgical complications during the first 3 months of follow-up were recorded, and associated risk factors were analyzed. Main Outcome Measures: The incidence of posttrabeculectomy complications was the main outcome measure. Results: One hundred and eighteen eyes of 118 patients were included. Early postoperative complications developed in 55 eyes (56.7%). Complications included hypotony (25 eyes, 27.2%), serous choroidal detachment (CD) (14 eyes, 15.6%), subconjunctival hemorrhage (12 eyes, 13.0%), hyphema (11 eyes, 12.4%), bleb leak (8 eyes, 8.8%), encapsulated bleb (2 eyes, 2.2%), aqueous misdirection (1 eyes, 1.1%), corneal epithelial defect (1 eyes, 1.1%), and overfiltration (1 eyes, 1.1%). There were no reported cases of endophthalmitis or blebitis. Hypotony was associated with serous CD (P = 0.006), and hyphema was associated with neovascular glaucoma (NVG) patients (P = 0.009). NVG was not associated with the increased rate of surgical failure (P = 0.083). Conclusions: The incidence of early complications after first-time trabeculectomy with MMC was high (56.7%) in this Thai clinic setting, but most were transient and self-limited conditions. The correlations between hypotony and CD as well as hyphema and NVG were compatible with the previous studies.

Cavernous hemangioma is the most common orbital tumor in adult. There is lot of literatures for clinicopathological features of this tumor. These tumors had been studied for the model of angiogenesis in many of the experimental setups. We present a case of 34-year-old male with this tumor in the left eye with computerized tomography evidence. Postsurgical laboratory findings gave interesting evidence of tumor angiogenesis with tumor endothelial cells and sprouting of the small vessels endothelial cells. Podosome rosette could be conceptualized from the characteristic patterns seen in the tumor.

Tick typhus causes hemorrhagic lesions over the skin. Retina also shows hemorrhages and exudates. Many cases have been reported in western literature about this condition. To our best of knowledge, this is the first case report of tick typhus in India which was also associated with inflammatory choroidal neovascularization.
