Biopsy techniques for intraocular tumors |
p. 415 |
Pukhraj Rishi, Abhinav Dhami, Jyotirmay Biswas DOI:10.4103/0301-4738.187652 PMID:27488148Biopsy involves the surgical removal of a tissue specimen for histopathologic evaluation. Most intraocular tumors are reliably diagnosed based on the clinical evaluation or with noninvasive diagnostic techniques. However, accurately diagnosing a small percentage of tumors can be challenging. A tissue biopsy is thus needed to establish a definitive diagnosis and plan the requisite treatment. From fine-needle aspiration biopsy (FNAB) to surgical excision, all tissue collection techniques have been studied in the literature. Each technique has its indications and limitations. FNAB has been reported to provide for 88-95% reliable and safe ophthalmic tumor diagnosis and has gained popularity for prognostic purposes and providing eye conserving treatment surgeries. The technique and instrumentation for biopsy vary depending upon the tissue involved (retina, choroid, subretinal space, vitreous, and aqueous), suspected diagnosis, size, location, associated retinal detachment, and clarity of the media. The cytopathologist confers a very important role in diagnosis and their assistance plays a key role in managing and planning the treatment for malignancies. |

p. 422 |
Koushik Tripathy, Rohan Chawla, Pradeep Venkatesh, Rajpal Vohra, Yog Raj Sharma DOI:10.4103/0301-4738.187656 PMID:27488149Purpose: The purpose of this study was to analyze the clinical profile of medicolegal cases (MLCs) presenting to the eye casualty in a tertiary care hospital. Materials and Methods: Retrospective review of records. The cases were grouped according to the Ocular Trauma Classification Group classification system. Results: Out of 188 MLCs, 164 (87.2%) were male. Mean age (±standard deviation) was 31.6 (±12.7) years. Age ranged from 7 to 75 years. Twenty-six (13.8%) patients had bilateral involvement. The fist was the most common mode of injury, which was seen in 109 (58%) cases. A total of 27 (14.3%) patients had associated extraocular injury. No evidence of ocular or orbital trauma (malingering) could be found in 13 (7%) patients. Mechanical trauma was present in 169 (90%) patients with injury to globe in 129 (69%) patients and injury to lid or orbit without damage to the globe in 40 (21%) patients. Chemical injury was observed in 6 (3%) patients. Closed globe injury (CGI) was seen in 116 eyes and open globe injury (OGI) was noted in 29 eyes. The most common type of injury, zone, pupil, and grade of injury in CGI were Type A or contusion (79%), Zone I (72%), Pupil B (absence of relative afferent pupillary defect) in 95%, and Grade A [visual acuity (VA) ≥20/40] in 68% of the eyes, respectively. The most common type of injury, zone, pupil, and grade of injury in OGI were Type B or penetrating (48%), Zone II (38%), Pupil B (59%), and Grade D (VA 4/200-light perception) (42%), respectively. Conclusions: The most common form and mode of ocular injury in MLC were closed globe injury and fist, respectively. The most common type of injury in CGI and OGI was contusion and penetrating injury, respectively. |

Change of retinal pigment epithelial atrophy after anti-vascular endothelial growth factor treatment in exudative age-related macular degeneration |
p. 427 |
Moosang Kim, Eung Suk Kim, Kyung Hoon Seo, Seung-Young Yu, Hyung-Woo Kwak DOI:10.4103/0301-4738.187659 PMID:27488150Purpose: The study aimed to investigate the quantitative changes of retinal pigment epithelial (RPE) atrophy during a 24-month follow-up period of anti-vascular endothelial growth factor (VEGF) for exudative age-related macular degeneration (AMD). Materials and Methods: This is a retrospective study. Sixty-five eyes of 62 consecutive patients with naοve exudative AMD who had received treatment with anti-VEGF therapy and followed for more 24 months were enrolled. All patients received three initial monthly injections of anti-VEGF (ranibizumab or bevacizumab), followed by pro re nata or treat-and-extend protocol. Color fundus image, optical coherence tomography, and fundus autofluorescence were evaluated for RPE atrophy. Multiple regression analysis was performed to investigate the predictive factors found during univariate analysis to identify an association with increased RPE atrophic areas. Results: The mean number of anti-VEGF treatments was 9.18. RPE atrophic area was 1.293 ± 1.298 mm 2 at baseline and enlarged to 2.394 ± 1.940 mm 2 after 24 months, which differed significantly (P = 0.001). Multiple regression analysis revealed that larger areas of RPE atrophy at month 4 and larger numbers of anti-VEGF treatments were associated with increased RPE atrophic areas. Conclusions: RPE atrophy progresses in eyes with exudative AMD during anti-VEGF treatment. Larger areas of RPE atrophy at month 4 and larger numbers of anti-VEGF injections were associated with an increased risk of progression of RPE atrophy the following treatment. These findings may be useful to clinicians using intravitreal anti-VEGF for the treatment of exudative AMD, both for selecting an appropriate treatment plan and for predicting the progression of RPE atrophy. |

Effect of thiamine pyrophosphate on retinopathy induced by hyperglycemia in rats: A biochemical and pathological evaluation |
p. 434 |
Emine Cinici, Ibrahim Ahiskali, Nihal Cetin, Bahadir Suleyman, Osman Kukula, Durdu Altuner, Abdulkadir Coban, Hilal Balta, Mehmet Kuzucu, Halis Suleyman DOI:10.4103/0301-4738.187666 PMID:27488151Purpose: Information is lacking on the protective effects of thiamine pyrophosphate (TPP) against hyperglycemia-induced retinopathy in rats. This study investigated the biochemical and histopathological aspects of the effect of TPP on hyperglycemia-induced retinopathy induced by alloxan in rats. Materials and Methods: The rats were separated into a diabetic TPP-administered group (DTPG), a diabetes control group (DCG) and a healthy group (HG). While the DTPG was given TPP, the DCG and HG were administered distilled water as a solvent at the same concentrations. This procedure was repeated daily for 3 months. At the end of this period, all of the rats were euthanized under thiopental sodium anesthesia, and biochemical and histopathological analyses of the ocular retinal tissues were performed. The results of the DTPG were compared with those of the DCG and HG. Results: TPP prevented hyperglycemia by increasing the amount of malondialdehyde and decreasing endogen antioxidants, including total glutathione, glutathione reductase, glutathione S-transferase and superoxide dismutase. In addition, the amounts of the DNA oxidation product 8-hydroxyguanine were significantly lower in the retinas of the DTPG compared to the DCG. In the retinas of the DCG, there was a marked increase in vascular structures and congestion, in addition to edema. In contrast, little vascularization and edema were observed in the DTPG, and there was no congestion. The results suggest that TPP significantly reduced the degree of hyperglycemia-induced retinopathy. Conclusions: The results of this study indicate that TPP may be useful for prophylaxis against diabetic retinopathy. |

Failure to initiate early insulin therapy - A risk factor for diabetic retinopathy in insulin users with Type 2 diabetes mellitus: Sankara Nethralaya-Diabetic Retinopathy Epidemiology and Molecular Genetics Study (SN-DREAMS, Report number 35) |
p. 440 |
Aditi Gupta, Kushal S Delhiwala, Rajiv P G Raman, Tarun Sharma, Sangeetha Srinivasan, Vaitheeswaran Kulothungan DOI:10.4103/0301-4738.187668 PMID:27488152Context: Insulin users have been reported to have a higher incidence of diabetic retinopathy (DR). Aim: The aim was to elucidate the factors associated with DR among insulin users, especially association between duration, prior to initiating insulin for Type 2 diabetes mellitus (DM) and developing DR. Materials and Methods: Retrospective cross-sectional observational study included 1414 subjects having Type 2 DM. Insulin users were defined as subjects using insulin for glycemic control, and insulin nonusers as those either not using any antidiabetic treatment or using diet control or oral medications. The duration before initiating insulin after diagnosis was calculated by subtracting the duration of insulin usage from the duration of DM. DR was clinically graded using Klein's classification. SPSS (version 9.0) was used for statistical analysis. Results: Insulin users had more incidence of DR (52.9% vs. 16.3%, P < 0.0001) and sight threatening DR (19.1% vs. 2.4%, P < 0.0001) in comparison to insulin nonusers. Among insulin users, longer duration of DM (odds ratio [OR] 1.12, 95% confidence interval [CI] 1.00-1.25, P = 0.044) and abdominal obesity (OR 1.15, 95% CI 1.02-1.29, P = 0.021) was associated with DR. The presence of DR was significantly associated with longer duration (≥5 years) prior to initiating insulin therapy, overall (38.0% vs. 62.0%, P = 0.013), and in subjects with suboptimal glycemic control (32.5% vs. 67.5%, P = 0.022). Conclusions: The presence of DR is significantly associated with longer duration of diabetes (>5 years) and sub-optimal glycemic control (glycosylated hemoglobin <7.0%). Among insulin users, abdominal obesity was found to be a significant predictor of DR; DR is associated with longer duration prior to initiating insulin therapy in Type 2 DM subjects with suboptimal glycemic control. |

Comparison of serum sodium and potassium levels in patients with senile cataract and age-matched individuals without cataract  |
p. 446 |
Gaurav Mathur, Vijaya Pai DOI:10.4103/0301-4738.99837 PMID:23552357Aim: The study was to analyze mean serum sodium and potassium levels in cataract patients and age-matched individuals without cataract. Methods and Materials: It was a prospective case-control study. Individuals more than 50 years of age who attended our ophthalmic center in the year 2007-2010 were grouped into those having cataract and those without cataract. Mean serum sodium and potassium levels in the cataract groups were calculated and compared with the control group. Statistical software SPSS14 was used for statistical analysis. Results: Mean serum sodium levels in cataract group was 135.1 meqv/l and 133 meqv/l in the control group. Mean potassium was 3.96 meqv/l in the case study group and 3.97 meqv/l in controls. Mean sodium levels among cases were significantly higher than control group. No difference was seen in the PSC group and control. The difference in mean potassium among the two groups was statistically insignificant. Conclusion: Diets with high sodium contents are a risk factor for senile cataract formation and dietary modifications can possibly reduce the rate of progression cataract. |

p. 448 |
Sadiya Iram, Winston D Prakash, Mohammad Javed Ali, Tarjani Vivek Dave, Milind N Naik DOI:10.4103/0301-4738.187674 PMID:27488153Purpose: The aims of this study were to determine the acceptability levels of different styles of the doctors' dress and the expectations from the initial phases of physician-patient encounter. Methods: The study design was a cross-sectional descriptive type using the survey methodology. A survey based on a five-point questionnaire was performed on all consecutive patients or their caregivers, aged ≥15, visiting the ophthalmic plastics outpatient clinics at a tertiary eye care institute. The participants were shown three sets of photographs and were required to answer a questionnaire which consisted of five questions. Data collected include participant demographics and their preferences with regards to the physician's attire and initial communications. Results: A total of 300 consecutive responses were analyzed. The mean age of the participants was 37.2 years. Among the participants, 87.6% (263/300) and 90.3% (271/300) preferred a white coat for the male and female physicians, respectively (P < 0.001). The most common second preference was scrubs for both the males and female physicians. 92.3% (277/300) preferred the attire to have an identification display. The overwhelming majority of respondents (95.6%, 287/300) preferred the physicians to address them by their name and 98.6% (296/300) liked if their physicians smiled while addressing them. Conclusions: White coat was the main preferred attire among respondents. Increased awareness of the patient's expectations plays a crucial role in enhancing their satisfaction. |

Correlation between retinal sensitivity and cystoid space characteristics in diabetic macular edema |
p. 452 |
Swetha B Velaga, Muneeswar G Nittala, B Parinitha, SR Sadda, Jay Kumar Chhablani DOI:10.4103/0301-4738.187675 PMID:27488154Purpose: To evaluate the correlation between retinal sensitivity and cystoid space characteristics in eyes with diabetic macular edema (DME). Materials and Methods: Prospective cross-sectional study of 22 subjects with DME (32 treatment-naïve eyes). All study subjects underwent complete ophthalmic examination, including slit-lamp biomicroscopy and dilated fundus examination. All subjects underwent spectral domain optical coherence tomography (SD-OCT) and microperimetry (MP). Intraretinal cystoid space (ICS) volume was generated after manual delineation of cystoid space boundaries using the three-dimensional-OCT software. Various SD-OCT parameters, including retinal thickness, retinal volume, cystoid space volume, cystoid space intensity, and outer retinal structure integrity, were correlated with MP parameters and best-corrected visual acuity (BCVA). Results: Subject's mean age was 57 ± 9 years. The mean logarithm of minimum angle of resolution BCVA was 0.4 ± 0.2. The intraclass correlation coefficient for inter- and intra-grader assessment of cystoid space volume by manual delineation was 0.99 and 0.99, respectively. Mean total ICS volume was 0.4 ± 0.4 mm 3 and for the foveal center, subfield was 0.1 ± 0.1 mm 3 . Mean retinal sensitivity was 12.89 ± 10 dB; however, foveal retinal sensitivity was 12.3 ± 11.1 dB. We found no significant correlation between BCVA and total cystoid space volume (r = 0.33, P = 0.06). Correlation between total retinal sensitivity and total ICS was negative and nonsignificant (r = −0.17, P = 0.36). Correlation between foveal retinal sensitivity and foveal cystoid space intensity was moderate and marginally significant (r = −0.43, P = 0.05). Conclusion: Total cystoid space volume was not significantly correlated with BCVA or total retinal sensitivity in subjects with DME. Foveal cystoid space optical intensity was negatively correlated with foveal retinal sensitivity. These findings suggest further investigation of cystoid space characteristics in the setting of DME may be of value. |

First case report of isolated aspergillus dacryoadenitis |
p. 462 |
Ishan Acharya, Divya Basa, M Kavitha DOI:10.4103/0301-4738.187678 PMID:27488157We report a case of isolated Aspergillus dacryoadenitis. A 23-year-old male presented with dull ache, diffuse swelling in superolateral quadrant of the right orbit and proptosis for 4 months. Ocular examination showed conjunctival congestion, discharge in the fornix and palpable lacrimal gland (LG) mass. Routine hematological investigations followed by computed tomography scan of orbits were done. He did not respond to a course of systemic and topical antibiotics. Lateral orbitotomy with extended lid crease incision was performed with excision biopsy of LG. Abundant blackish material was found in the LG intraoperatively. The specimen was sent for histopathological examination (HPE). HPE report showed Aspergillus. Thorough ENT and systemic evaluation ruled out any other site with the fungus. To the best of our knowledge, this is the first case report of Aspergillus infection in LG. |

Purtscher-like retinopathy: A rare complication of peribulbar anesthesia |
p. 464 |
Siddharth Narendran, VR Saravanan, Merlyn Pereira DOI:10.4103/0301-4738.187679 PMID:27488158Purtscher and Purtscher-like retinopathy is a distinctive retinal syndrome characterized by ischemic retinal whitening in a peripapillary pattern. We report a case of Purtscher-like retinopathy in a healthy 64-year-old man after a routine peribulbar anesthetic injection for cataract surgery. Although peribulbar anesthesia is considered to be a safer alternative to retrobulbar anesthesia, it has been associated with unusual but grave complications including central retinal artery occlusion. |

Solid variant of orbital angioleiomyoma: An unusual tumor at an unusual site |
p. 466 |
Akshay Gopinathan Nair, Vandana Jain, Indumati Gopinathan, Anuradha Murthy DOI:10.4103/0301-4738.187680 PMID:27488159We describe the clinicopathological features of a solid variant of orbital angioleiomyoma. A review of clinical records, diagnostic, and radiographic studies combined with histopathological evaluation with standard histochemical staining and immunohistochemistry was conducted. A 22-year-old male patient presented with a mass in the region of the left lacrimal gland that was gradually increasing over the past 2 years. Radiological and clinical examinations showed no signs suspicious of a malignancy and fine needle aspiration cytology was inconclusive. Therefore, an excision biopsy was performed. On histopathological examination, the picture was consistent with a benign spindle cell tumor. Immunohistochemistry showed positivity for CD 34 and CD 31 (markers for vascular endothelium). The tumor also showed positivity for smooth muscle actin and Ki-67 proliferative index was low. Angioleiomyomas are rarely encountered in the orbit and has features seen in leiomyoma as well as some vascular tumor elements. In most cases, surgical excision is usually curative. |

Unilateral anterior persistent fetal vasculature in a child with blepharophimosis-ptosis-epicanthus inversus syndrome: A surgical challenge |
p. 469 |
Vasudha Kemmanu, Pragnya Rathod, Hemant Anaspure, Naresh K Yadav DOI:10.4103/0301-4738.187681 PMID:27488160Blepharophimosis-ptosis-epicanthus inversus syndrome (BPES) is a rare autosomal dominant genetic disease. It is clinically characterized by four major features; blepharophimosis, ptosis, epicanthus inversus, and telecanthus. We report a case of a 1-year-old female with BPES with unilateral anterior persistent fetal vasculature (PFV). On examination, she was found to have all the clinical features of BPES, along with calcified and partially absorbed cataract with elongated ciliary processes in her left eye. B-scan of left eye showed attached retina with no evidence of posterior PFV. Systemic examination was normal. She underwent cataract surgery with primary posterior capsulotomy with intraocular lens implantation under general anesthesia. Literature search did not reveal any previous reports of unilateral anterior PFV and BPES. The clinical features, other associations, and the difficulties in the surgical management of this condition are discussed. |
