Aim: The aim of this study was to evaluate the safety and efficacy of biosimilar intravitreal ranibizumab (Razumab) for the treatment of chorioretinal vascular diseases such as diabetic macular edema (DME), neovascular age-related macular degeneration (nAMD), and macular edema secondary to retinal vein occlusions (RVOs). Methods: A prospective analysis was performed on consented patients with DME (Group 1), nAMD (Group 2), and macular edema secondary to RVO (Group 3). All patients received Razumab at baseline. Snellen visual acuity assessment, anterior segment and fundus evaluation, fundus photo, and optical coherence tomography imaging were done at days 0, 1, 7, and 30, respectively. The International Society for Clinical Electrophysiology of Vision standard electroretinography (ERG) was performed at baseline and day 30 (23 eyes who could afford the investigation). Primary and secondary outcome measures were safety parameters that included signs of clinical and ERG toxicity and changes in best-corrected visual acuity (BCVA) and central macular thickness (CMT), respectively. Results: One hundred and twenty-three eyes of 95 patients received biosimilar intravitreal ranibizumab injection between November 2015 and April 2016. No serious drug-related ocular or systemic adverse events were identified. Mean pretreatment BCVA was 0.67 ± 0.41 logMAR with CMT 345.90 ± 128.84 μm and postinjection BCVA at day 30 was 0.57 ± 0.37 logMAR with CMT reducing to 287.66 ± 90.28 μm, indicating statistical significance (P = 0.001 and P< 0.0001, respectively) for all groups. Conclusion: The biosimilar intravitreal ranibizumab for DME, nAMD, and macular edema secondary to RVO was tolerated over a month with improvements in BCVA and CMT without detectable ocular and systemic toxicity. While the long-term safety and efficacy remain unknown, these short-term results suggest that biosimilar ranibizumab could become a safe, low-cost therapy for macular diseases.

The bullous variant is a rare manifestation of central serous retinopathy (CSR). Multiple therapeutic approaches have been described to treat these bullous detachments which mainly involve laser photocoagulation or surgical drainage. Here, we demonstrate the efficacy of oral eplerenone in the treatment of the bullous variant of CSR. A 44-year-old female presented to us with diminution of vision in the left eye (OS) for 1 month. On clinical examination, she was diagnosed to have a chronic CSR in both eyes along with a bullous retinal detachment in the OS which was confirmed on multimodal imaging. She underwent focal laser, which failed to resolve the bullous variant in the OS, then the patient was started on oral eplerenone for 3 months. At 3-month follow-up, the ultrasound scan of the OS confirmed resolution of the bullous detachment, and some residual subretinal fluid could be noted at the posterior pole. This was maintained till 6-month follow-up. Oral eplerenone can be an effective, cheap, and safer alternative in treating patients with nonresolving bullous detachments secondary to chronic CSR.

Aim: To study the effectiveness of prisms in relieving diplopia in patients with superior oblique palsies. Materials and Methods: This was a retrospective study of all patients with superior oblique palsies who were prescribed prisms for relief of symptomatic diplopia in our institute from September 2013 to March 2015. A detailed analysis was performed of demographic features of the patients; nature, onset, duration, and course of diplopia; measurement of deviation in all gazes; diplopia charting; assessment of torsion; systemic risk factors; and amount and type of prism given. The effectiveness of prisms was measured by an objective score by the examiner as well as a subjective score reported by the patient. Results: Among the total 25 patients, 21 patients had acquired superior oblique palsies and 4 patients had congenital causes. Males outnumbered females. Majority had unilateral involvement. Deviation in primary position ranged from 3 Prism Dioptre to 25 PD with 80% having less than 10 PD. Seventy-six percent had less than 10° torsion in primary gaze. Eighty-eight percent were given less than 10 PD prisms, 12% were given more than 10 PD, of which two were Fresnel Prisms. Seventy-six percent were satisfied with the prisms. Fifty-two percent had spontaneous improvement whereas 16% needed surgery. Conclusion: Prisms were effective in relieving diplopia in most of the acquired unilateral superior oblique palsies where the primary deviation was less than 10 PD and torsion was less than 10°.

Eyelid malpositions are the result of forces acting upon the eyelid margin. A normal eyelid should have a quick return snap to the eyeball. Frequently, tendon laxity at the medial and lateral canthi will render the eyelid margin unstable making it susceptible to contractile forces. Based on the contractile forces either entropion, ectropion, retraction or lagophthalmos can occur. The goal in treating a given eyelid malposition is to reposition the eyelid so that the new healing forces will overcome the pathologic forces. The common approaches include eyelid and canthal tendon tightening, eyelid retractor advancement or recession and skin grafting or transposition flaps. This review article briefly describes the various aspects of lid malpositions in detail.

Retinopathy of prematurity (ROP) is a vasoproliferative disease that affects premature infants. ROP is on a rise in India as a result of the improved neonatal care and better neonatal survival rate. Identifying and screening of at-risk premature infants performed by an experienced ophthalmologist remains the most important strategy in the management of ROP. In developing countries, the introduction of Retcam-assisted screening enables screening and follow-up of the rural population where an experienced ophthalmologist may not be available. Currently, laser photocoagulation of avascular retina has replaced cryotherapy as the gold standard treatment for ROP depending on the severity of disease. Among the various ongoing treatment approaches currently under trial to suppress the neovascularization, anti-vascular endothelial growth factor drugs provide valuable and encouraging information, especially in Zone 1 disease. Although many ongoing animal trials aimed at finding an ideal treatment have come out with newer treatment options, their safety and efficacy in humans are yet to be established.

Optical coherence tomography angiography (OCTA) is a non-invasive angiography type without a contrast agent, which provides a detailed assessment of the retinal and choroidal vasculature and visualization of blood flow by detecting motions of erythrocytes, using serial optical coherence tomography B-scans. As compared to gold standard techniques such as fluorescein and indocyanin-green angiography, OCTA offers two major advantages: no dye is required and depth resolution is required is provided. As such OCTA has the potential to improve our abilities to diagnose and monitor ocular vascular diseases.

Background: Creating awareness regarding eye donation is the prime factor responsible for promoting voluntary pledging and donation of eyes. Planning awareness campaigns is determined by the prevalence of dearth of understanding of eye donation. Aims and Objectives: To assess the awareness and perception among eye care seekers toward eye donation. Material and Methods: A cross-sectional study was conducted among patients attending ophthalmology outpatient department seeking eye care, using a predesigned, pretested, semistructured, selfadministered questionnaire. Results: The study group included 250 participants. The male to female ratio was 1:1. A total of 94.4% participants had heard about eye donation. A total of 71.7% were willing to donate their eyes; 90.3% had not pledged their eyes; 63.7% were ready to implement eye donation as a family custom. Willingness, consent, and wish to make eye donation as a family custom was more among males (P = 0.049), graduates (P = 0.013), Christians (P = 0.019), those who were aware of the subject (P = 0.00), and who were single (P = 0.00). Only 7.6% had faced discouragement from the society or kith and kin when pledging of eye was considered. A total of 66.1% knew about the existence of a registered eye bank in the institute. Nobility was the main motivation (87.7%). A total of 61.8% felt that donated eye can give vision to the needy. Conclusion: This study revealed that eye care seekers were well aware of eye donation with a favorable attitude towards it; most of them were inclined to pledge their eyes. Counseling of this receptive group and identifying interested candidates among them as volunteers for eye donation is helpful in promoting eye donation among the community.
