Evaluating ocular blood flow
Jyotsna Maram, Sowmya Srinivas, Srinivas R Sadda
May 2017, 65(5):337-346
DOI:10.4103/ijo.IJO_330_17  PMID:28573987
Studies have shown that vascular impairment plays an important role in the etiology and pathogenesis of various ocular diseases including glaucoma, age-related macular degeneration, diabetic retinopathy, and retinal venous occlusive disease. Thus, qualitative and quantitative assessment of ocular blood flow (BF) is a topic of interest for early disease detection, diagnosis, and management. Owing to the rapid improvement in technology, there are several invasive and noninvasive techniques available for evaluating ocular BF, with each of these techniques having their own limitations and advantages. This article reviews these important techniques, with a particular focus on Doppler Fourier domain optical coherence tomography (OCT) and OCT-angiography.

Mittanamalli S Sridhar, Advithi Rangaraju, Kavitha Anbarasu, Sharat Putta Reddy, Sachin Daga, Sita Jayalakshmi, Bajibhi Shaik
May 2017, 65(5):354-357
DOI:10.4103/ijo.IJO_400_16  PMID:28573989
Purpose: The purpose of the study is to present anterior segment optical coherence tomography (AS-OCT) as an alternative method of evaluating Kayser–Fleischer (KF) ring in Wilson disease (WD) not only by ophthalmologists but also by other clinicians dealing with WD. Materials and Methods: This was a retrospective case series of six WD patients with KF ring. Evaluation of KF ring was done by naked eye examination using torch light, slit lamp biomicroscopy (SL), and AS-OCT. SL examination was done using a narrow slit of the superior cornea. AS-OCT was done using the Optovue RTvue PremierTM device (Fremont, CA, USA). Results: AS-OCT revealed KF ring as an intense hyperreflective band at the level of Descemet membrane (DM). Color scale of AS-OCT showed KF ring as greenish/greenish yellow/orange yellow/yellowish/red band. Validation of AS-OCT findings was done by second ophthalmologist, medical gastroenterologist, surgical gastroenterologist, and neurophysician. After seeing the first observation, they could identify the AS-OCT features in all pictures with ease. Conclusions: This is the first observation of KF ring in WD on AS-OCT. On AS-OCT, KF ring is visualized as intense hyperreflectivity at the level of DM in the peripheral cornea. Further, studies are needed to evaluate the usefulness of AS-OCT in WD management.

Sri Ganesh, Sheetal Brar, Rohit Sreenath
May 2017, 65(5):358-364
DOI:10.4103/ijo.IJO_947_16  PMID:28573990
Purpose: The purpose of this study is to evaluate the safety and benefits of immediate sequential bilateral cataract surgery. Patients and Methods: Retrospective data analysis of patients who underwent immediate sequential bilateral phacoemulsification with foldable intraocular lens (IOL) implantation under topical anesthesia from January 2011 to September 2016 was performed. Patients with visually significant bilateral cataract within the axial length range of 21.0–26.5 mm were included in the study. Intraoperative and postoperative complications were evaluated. Results: Two thousand four hundred and seventy eyes from 1235 patients with a mean age of 68.34 years (range: 4–90 years) were analyzed. Best-corrected visual acuity improved from 0.40 ± 0.17 to 0.08 ± 0.10 (logarithm of the minimum angle of resolution). Nearly 92.05% eyes achieved a target postoperative refraction of ± 0.5 D spherical equivalent. Main complications observed were prolonged postoperative inflammation in 25% (n = 31), posterior capsular tears in 0.45% (n = 11), and unilateral cystoid macular edema in 0.08% (n = 2) eyes. No sight-threatening complications such as endophthalmitis, retinal detachment, corneal decompensation and intraocular hemorrhage occurred in any of the eyes. Out of the 288 (23.2%) patients who underwent bilateral multifocal IOL implantation, 23 patients (46 eyes) had femtolaser-assisted cataract surgery procedure. Two pediatric and one Downs syndrome patient underwent bilateral cataract surgery under general anesthesia and intravenous sedation, respectively. Conclusion: IBSCS may be considered as a preferred practice in eligible cases considering significant patient benefits such as early visual rehabilitation, time and cost-effectiveness, and better compliance with postoperative medications. In debilitated patients and special situations, such as pediatric cataract and Downs syndrome requiring general anesthesia it may be the ideal procedure.

Anand Vinekar, Shwetha Mangalesh, Chaitra Jayadev, Clare Gilbert, Mangat Dogra, Bhujang Shetty
May 2017, 65(5):390-395
DOI:10.4103/ijo.IJO_211_17  PMID:28573995
Purpose: The purpose of this study is to estimate the unknown burden of retinopathy of prematurity (ROP) blindness from nine states of India using demographic, incidence and treatment data from an ongoing statewide ROP program in Karnataka called the Karnataka Internet Assisted Diagnosis of ROP (KIDROP) and to calculate the fiscal quantum of preventable blindness in these states. Materials and Methods: The KIDROP model is an ongoing tele-ROP service providing screening and treatment for ROP in Karnataka since 2008. Using this index strategy, an impact assessment in nine other states was constructed, the number of potential blind babies enumerated, the fiscal quantum of blindness prevented in blind person-years (BPYs), and the increase in burden with improving survival and institutional deliveries calculated. Results: The total population in the ten study states is 681.5 million. The eligible babies for ROP screening annually are 467,664. The number of babies admitted to neonatal units is 188,561 of which 160,277 are likely to survive and require screening. Based on KIDROP data, ROP would develop in 35,886 of these infants, and 1281 babies would require treatment annually. The fiscal quantum of BPY saved in these ten states is USD 108.4 million annually, with a further increase of USD 106.8 million with improving infant survival and higher admission rates for delivery. Conclusion: A KIDROP like model can provide ROP screening in low-resource settings, remote centers, and regions with few ROP specialists. Expanding the model to other states with similar demographics can prevent over USD 100 million of blindness burden annually.

Antiretinal antibody- proven autoimmune retinopathy
Sharanya Abraham, S Sudharshan, Muna Bhende, Sudha K Ganesh, Sriram Gopal
May 2017, 65(5):416-420
DOI:10.4103/ijo.IJO_838_16  PMID:28574003
A young female presented with bilateral subacute onset of progressive decrease in night vision and reduced peripheral field of vision. The short duration and rapid progression of symptoms along with the lack of family history of night blindness prompted a diagnosis of autoimmune retinopathy (AIR). Fundus fluorescein angiography, optical coherence tomography, visual fields, and electroretinogram were suggestive of AIR. A differential diagnosis of retinitis pigmentosa (RP) was also made. Antiretinal autoantibodies were detected in the blood sample. Treatment was with oral steroids and subsequently oral immunosuppressive agents. Visual acuity was maintained, fundus examination reverted to normal, and investigations repeated at every visit were stable with improvement in visual fields. Our case suggests that AIR, if diagnosed early and treated appropriately, may have a good outcome and should be considered in patients with an atypical presentation of RP.

Delayed follow-up in patients with diabetic retinopathy in South India: Social factors and impact on disease progression
Natrajan Vengadesan, Meleha Ahmad, Manavi D Sindal, Sabyasachi Sengupta
May 2017, 65(5):376-384
DOI:10.4103/ijo.IJO_620_16  PMID:28573993
Purpose: To identify social factors associated with delayed follow-up in South Indian patients with diabetic retinopathy (DR) and to study DR progression during the delayed follow-up period. Materials and Methods: In this cross-sectional study, 500 consecutive patients with DR returning after greater than twice the advised follow-up period were identified from a tertiary referral center in South India. A previously validated 19-item questionnaire was administered to study patients to assess causes for the follow-up delay. Patient demographics, DR status, and treatment plan were recorded at the study visit and the visit immediately before the delay. The eye with the most severe disease was included in the analysis. Results: Complete data were available for 491 (98.2%) patients. Among these, 248 (50.5%) cited “my eyes were okay at the time,” 201 (41.0%) cited “no attender to accompany me,” and 190 (38.6%) cited “financial cost” as causes of the follow-up delay. Those with vision-threatening DR (VTDR, n = 233) predominantly reported “financial cost” (47% vs. 32%, P= 0.001), whereas those with non-VTDR more frequently reported “my eyes were okay at the time” (58% vs. 42%, P= 0.001). Evidence of disease progression from non-VTDR to VTDR was seen in 67 (26%) patients. Almost 1/3rd (29%) of patients who were previously advised regular examination required additional intervention. Conclusion: Many patient-level factors affect poor compliance with follow-up in DR, and these factors vary by disease severity. Targeting these barriers to care through patient education and clinic procedures may promote timely follow-up and better outcomes in these patients.

May 2017, 65(5):413-416
DOI:10.4103/ijo.IJO_544_16  PMID:28574002
Vogt-Koyanagi-Harada (VKH), a multisystem autoimmune bilateral panuveitis with systemic manifestations, is uncommon in immunocompromised patients such as human immunodeficiency virus (HIV)/acquired immunodeficiency disease syndrome (AIDS). We report a rare presentation of VKH in a 45-year-old HIV-positive female on highly active antiretroviral therapy (HAART) who presented with a history of recurrent panuveitis. A diagnosis of probable VKH was made based on ocular and systemic signs and symptoms. She was treated with topical and systemic steroids with close monitoring of CD4 counts and viral loads. After inflammation control, complicated cataract was managed surgically under perioperative steroid cover. VKH in HIV/AIDS has not been reported earlier. This case shows that significant inflammation can be seen even in HIV/AIDS patients on HAART with VKH in spite of moderate CD4 counts. Management is a challenge considering the systemic risks with long-term use of steroids.

Rohit Shetty, Shraddha Sureka, Pallak Kusumgar, Swaminathan Sethu, Kanchan Sainani
May 2017, 65(5):399-402
DOI:10.4103/ijo.IJO_217_17  PMID:28573997
We report two male children with persistent allergic eye disease (AED) and keratoconus (KC). Both presented with symptoms of vernal keratoconjunctivitis and decreased vision. In view of unrelenting AED, serum immunoglobulin E (IgE) quantification and identification of specific allergens were advised. Increased serum IgE levels were observed in both cases. Sunflower and sheep wool were identified as specific allergens for the first and second patient respectively by skin patch test. There was complete resolution of symptoms of AED in both patients following avoidance of causative allergens. However, the progression of KC in both eyes of the first patient and one eye of the second patient was observed. They were advised collagen cross-linking. Elevated serum IgE indicates the presence of systemic allergy. Avoiding implicated allergens help alleviate ocular symptoms. Using serum IgE and identifying specific allergen can guide in the treatment of AED and thus prevent progressive KC due to eye rubbing and resulting inflammation.

Surgical refixation of posteriorly dislocated intraocular lens with scleral-tuck technique
Pukhraj Rishi, Ekta Rishi, Aditya Maitray
May 2017, 65(5):365-370
DOI:10.4103/ijo.IJO_960_16  PMID:28573991
Purpose: To report the outcomes of surgical refixation of posteriorly dislocated intraocular lens (IOL) using scleral-tuck method, and to compare the “scleral groove” and the “scleral flap” techniques used. Study Design: Single-center, retrospective, interventional, comparative study. Methods: Medical records of patients undergoing closed globe scleral refixation of posteriorly dislocated posterior chamber IOL (PCIOLs) by scleral-tuck method using two different techniques (”scleral groove” vs. “scleral flap” technique) were reviewed. This approach involved retrieving the dislocated PCIOL, externalizing the haptics through 2 sclerotomies created in paralimbal lamellar scleral grooves, or under lamellar scleral flaps and tucking the haptics into limbus-parallel scleral tunnels. No specific haptic architecture, haptic suturing, or large incisions were needed. Main outcome measures included best-corrected visual acuity (BCVA), final mean refractive error, and intra- and post-operative complications. Results: Thirteen eyes of 13 patients (scleral groove, n = 6; scleral flap, n = 7 eyes) with a mean follow-up of 20.6 months were included. BCVA in all eyes was maintained or improved postoperatively, with three eyes (23%) showing ≥2 line improvement. Median astigmatic error at 6-week follow-up was −1.25 D cylinder (range: −0.5 D–−2.0 D) which remained stable till final follow-up. All IOLs remained stable and well centered. None of the eyes had a recurrent dislocation, retinal detachment, endophthalmitis, or glaucoma. Both techniques were comparable in terms of postoperative BCVA, and refraction. Conclusion: Intrascleral haptic fixation by scleral-tuck method is reliable and effective for secure IOL refixation of posteriorly dislocated IOLs, providing good IOL centration and stability with minimal surgically-induced astigmatism. Both techniques (scleral groove and scleral flap) appear to have similar outcomes in the short term.

DOI:10.4103/ijo.IJO_656_16  PMID:28573999
Leiomyosarcoma is a malignant mesenchymal tumor that is very uncommon in the conjunctiva. Nevertheless, we describe here the clinical manifestations, management, and prognosis of a rare case of leiomyosarcoma in this location. An 81-year-old male presented at a tertiary hospital with a rapidly growing mass. After performing biopsy, histopathological examination revealed the existence of a conjunctival leiomyosarcoma. On this diagnosis, a thorough metastatic screening was performed showing no enlarged lymph nodes or metastatic deposits anywhere in the body. To treat the condition, we performed an evisceration with clear margins and subsequent radiotherapy.

DOI:10.4103/ijo.IJO_963_16  PMID:28574004
Optic disc pit (ODP) is rare congenital cavitary anomaly of the optic disc. Serous detachment of macula is the most common complication of ODP and occurs in 25%–75% of these cases. Although various surgical techniques have been used for the treatment of ODP maculopathy; consensus still eludes as far as the optimal surgical approach is concerned. We herein report a case of ODP maculopathy in a young female treated successfully with vitrectomy, fovea sparing internal limiting membrane flap, and C3F8 tamponade.

DOI:10.4103/ijo.IJO_836_16  PMID:28573998
Aspergillus and Fusarium are the most common fungi causing mycotic keratitis. Injury to the eye with vegetable matter, cow tail injury, long-term use of topical steroids are some of the risk factors for mycotic keratitis. There are few case reports of keratitis caused by Bipolaris. The human pathogenic species in the genus are Bipolaris spicifera, Bipolaris hawaiiensis, Bipolaris papendorfii, and Bipolaris australiensis. Most commonly reported keratitis is caused by B. hawaiiensis, followed by B. spicifera. Literature review showed only one case report of keratitis due to B. australiensis reported from Australia. We present a first case report of keratitis due to B. australiensis (currently Curvularia australienis) from India.

May 2017, 65(5):371-375
DOI:10.4103/ijo.IJO_564_16  PMID:28573992
Purpose: To study the outcome of ocular nocardiosis following intraocular surgery. Materials and Methods: A retrospective review of medical records of all postoperative cases of culture proven Nocardia infection over a period of 3 years, from October 2010 to September 2013, was performed. Microbiological analysis was performed for all cases and included smears and cultures. Fortified 2% amikacin eye drops were the mainstay of treatment. Surgical intervention was performed in case of nonresponse to medical therapy or suspected endophthalmitis. Results: Seven cases of culture proven Nocardia infection were seen. All cases had been operated in a hospital surgical facility. Six followed phacoemulsification, and one followed a secondary intraocular lens implantation. Four patients were part of a cluster infection. The mean duration between the primary surgical procedure and presentation was 16.14 ± 9.82 days. Five patients had infiltrates at the site of the surgical incision. One each had endophthalmitis and panophthalmitis. Six eyes required surgical intervention. Infection was seen to resolve in four eyes. Two eyes went into phthisis, and one was eviscerated. Only two of the six eyes, where in surgical intervention was performed early, obtained a final visual acuity of 20/60. Conclusion: Early surgical intervention, before the involvement of the anterior chamber, may help preserve the anatomic and functional integrity of the eye.

Jitendra Jethani, Monika Jethani, Sonal Amin
May 2017, 65(5):396-398
DOI:10.4103/ijo.IJO_214_14  PMID:28573996
Background and Aim: Rectus muscle insertions are usually linear or slight curved with the anterior convexity. While operating squint surgeries, we found a presence of ridge-like structure at the medial rectus insertion. None of the other rectus muscle insertions had such structure. Materials and Methods: Patients undergoing squint surgery were included in the study. All the patients had negative forced duction test for all the gazes and had comitant strabismus. The patients underwent surgery through the fornix route. All the squint surgeries were primary. None of the patients undergoing resurgery were included in the study. The ridge seen is actually an elevated curved structure and shows discontinuation of the actual medial rectus insertion. The measurements were taken from the superior and inferior end of the medial rectus muscle insertion. Results: In a total of 76 medial rectus surgery (for recession or resection), we found the ridge was present in 68 (89.5%) of cases. The ridge was located at an average distance of 6.33 ± 1.5 mm inferior and 3.82 ± 0.9 mm superior to the superior and inferior point of medial rectus insertion, respectively. Conclusion: We describe the presence, morphology, and measurements of a ridge as an anatomical landmark at medial rectus insertion.

Rohan Chawla, Seema Meena, Ankit Singh Tomar, Pradeep Venkatesh, Rajpal Vohra
May 2017, 65(5):411-413
DOI:10.4103/ijo.IJO_712_16  PMID:28574001
This case report describes the concurrent development of Vogt–Koyanagi–Harada (VKH) disease in a 39 year old male patient of chronic myeloid leukemia (CML). The patient being reported was a known case of CML in remission with history of painless sudden loss of vision in both eyes. Cases of leukemia can present with visual loss due to multiple ocular manifestations of leukemia itself or side effects of modern drugs used for its treatment. Clinical examination and multimodal imaging of our patient were suggestive of concurrent development of VKH. The patient was started on oral steroids, to which he showed a good response. Thus, the cases of CML may rarely develop concurrent ocular disorders not related to leukemia. These associated ocular disorders need to be distinguished from the ocular manifestations of leukemia itself. Our case highlights the concurrent development of VKH as the etiology of visual loss in a case of CML.

DOI:10.4103/ijo.IJO_809_16  PMID:28574000
We describe a female patient who presented with watering followed by swelling in the left infraorbital area of 5 years duration. She had previously been prescribed topical antibiotics on several occasions with no improvement. On pressure over the swelling, there was blood-tinged discharge from the left eye and nostril. Magnetic resonance imaging revealed an enhancing, well-defined mass lesion in the inferomedial aspect of the left orbit, likely of nasolacrimal origin. Computed tomography dacryocystogram with three-dimensional reconstruction showed a well-circumscribed mass with an irregular surface, originating from the lacrimal sac. Gram staining and potassium hydroxide mount from the regurgitant fluid revealed thick-walled cysts with sporangia suggestive of Rhinosporidium seeberi infection. Excision biopsy of the lesion confirmed R. seeberi as the causative agent. The patient has been put on long-term dapsone therapy to prevent a recurrence and has been asked to follow-up 6 months later.

May 2017, 65(5):385-389
DOI:10.4103/ijo.IJO_984_16  PMID:28573994
Introduction: To compare mean best-corrected visual acuity (BCVA), retinal sensitivity (RS), and bivariate contour ellipse area (BCEA) in patients with adult-onset foveomacular vitelliform dystrophy (AOFVD) and healthy subjects (HSs), reporting also functional disease-related changes in the different stages of the AOFVD disease. Materials and Methods: In this observational cross-sectional study, a total of 19 patients (30 eyes; 12 female and 7 male) with AOFVD were enrolled, and 30 patients (30 eyes; 16 female and 14 male) were recruited as age-matched control group (74.36 ± 9.17 years vs. 71.83 ± 6.99 years respectively, P= 0.11). All patients underwent a complete ophthalmologic examination, fundus autofluorescence and fluorescein angiography, spectral-domain optical coherence tomography and microperimetry (MP)-1 analysis. The data collection included mean BCVA, mean RS measured by means of MP-1, BCEA, and central retinal thickness. Results: All the functional parameters (BCVA, RS, and BCEA) were significantly worse in AOFVD group than HS. Subgroup analysis showed that the most significant functional changes, quantified by mean BCVA, RS, and BCEA, were in the atrophic stage (P = 0.03, P= 0.01, and P= 0.001, respectively). All the functional parameters were well correlated in the different stages. Conclusions: This study further confirms the good visual prognosis in the AOFVD eyes. Fixation stability measurement using BCEA demonstrates good evaluation of visual performance integrating traditional functional parameters. It may also serve for further rehabilitative purposes in atrophic eyes.
