Purpose: Retinopathy of prematurity (ROP) is a preventable cause of childhood blindness. Identification of risk factors is essential for its early detection and management. Aim: The aim of this study was to analyze the incidence and risk factors of Retinopathy of Prematurity in preterm babies admitted in neonatal care unit over the period of one year. Materials and Methods: A clinical retrospective study was done among 259 preterm babies referred to our department from October 2014 to September 2015 for screening of ROP. Fundus examination with indirect ophthalmoscope (IDO) was done. Babies with manifestation of ROP were followed-up for progression and managed appropriately. Results: One hundred and forty-two (54.8%) babies were found to have ROP at various stages. In very low birth weight (VLBW) babies (<1000 g; n = 40), 34 (85%) had ROP, out of which 19 (55.9%) had significant disease. Among LBW neonates (<1500 g; n = 165), 108 (65.45%) had ROP, out of which 37 (34.3%) had significant disease (P < 0.05). In neonates less than 28 weeks (n = 33), 25 (75.8%) had ROP, out of which 14 (56%) had significant disease. Out of the 103 babies who had RDS, 61 (59.2%) babies developed ROP, out of which 20 (32.8%) had significant disease. Conclusion: Prematurity and LBW were found to be independent risk factors in development of ROP in neonates.

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.

Real-time intraoperative optical coherence tomography (iOCT) integrated into the operating microscope can be used for optimizing the outcome of lamellar corneal surgeries. Surgical technique can be modified intraoperatively by its use, and surgical endpoint can be achieved in the operating room itself. We have successfully utilized the use of iOCT for refining the endpoint of surgical procedures such as deep anterior lamellar keratoplasty, descemet stripping automated endothelial keratoplasty, descemet membrane endothelial keratoplasty, and superficial anterior lamellar keratoplasty. Continuous iOCT imaging is a new technique that allows an accurate estimation of the depth of dissection, aiding in the modification of surgical planning.

Hepatitis C virus (HCV) is a blood-borne RNA virus that causes hepatitis C, chronic liver disease, and hepatocellular carcinoma. Patients with HCV infection are now treated with a combination of interferon alpha, which has antiviral and immunomodulatory properties, and ribavirin, an antiviral medication included in the family of nucleoside analogs. Recently, a long acting form of interferon alpha (pegylated interferon) has been developed, which has a more sustained antiviral response. One of the ocular side effects of interferon alpha is proliferative retinopathy related to ischemia. Interferon-associated retinopathy is usually mild and resolves completely, but occasionally, it can become severe.

Introduction: Both glaucoma and cataract often coexist in the elderly population. In these patients, a combined surgery has advantages such as improved vision and intraocular pressure (IOP) reduction in a single sitting. Aim: The aim of this study was to evaluate the effectiveness and safety of the combined procedure in patients with coexisting cataract and primary open or closed-angle glaucoma. Materials and Methods: A prospective study was conducted which included 20 eyes of 17 patients planned for phacotrabeculectomy procedure. Preoperative evaluation included detailed ocular examination for the grade of cataract, glaucoma evaluation, and exclusion of ocular comorbidities. A superior trabeculectomy with mitomycin C and temporal phacoemulsification with in the bag intraocular lens implantation was performed. Postoperatively, improvement in the best corrected visual acuity, IOP control, and reduction in the number of antiglaucoma medications was evaluated. Patients were followed for a 6-month period. Results: Postoperatively, all the patients had significant improvement in best corrected visual acuity (P < 0.0001) and significant reduction in IOP. The usage of antiglaucoma medication was lower (P < 0.0001) and 85% percent (17 eyes) had no complications. Conclusion: Combined phacoemulsification and trabeculectomy is an effective and safe procedure to provide good visual acuity and control of intraocular pressure at the same time.

Purpose: To determine whether preoperative cone outer segment tips (COST) line, ellipsoid zone (EZ), and external limiting membrane (ELM) defects is significantly related with postoperative recovery of photoreceptors and vision after type 1 macular hole closure. Materials and Methods: A retrospective observational study was conducted on 28 eyes of 28 patients with surgically closed macular holes. Heidelberg's Spectralis optical coherence tomography (OCT) was used to obtain images of the foveal area, and lengths of COST line defect, EZ defect, and ELM defect were measured preoperatively and at 1 month, 3 months, and 6 months after surgery. The pattern of recovery of the photoreceptor layers was observed as complete recovery, incomplete recovery, or disrupted. Results: It was observed that 13 out of 28 eyes with a mean preoperative length of foveal COST line defect 303.8 microns, showed a significant visual improvement in the range of 0.17 logMAR units (6/9-6/6) with complete or incomplete recovery of the EZ and ELM. Twelve patients with mean preoperative length of foveal COST line defect 632 microns showed only slight visual improvement by one or two lines in the range of 0.47 logMAR units (6/18), with an incomplete pattern of photoreceptor recovery. However, 3 patients with a mean preoperative COST line defect of 815 microns did not show any visual improvement of 0.61 logMAR units (6/36) with EZ and ELM disruptions postoperatively. Conclusion: The length of preoperative COST line defect is predictive of the recovery and arrangement of photoreceptors and best corrected visual acuity after type 1 macular hole closure. Eyes with complete and incomplete recovery of COST, EZ, and ELM were associated with significantly better visual acuity as compared to eyes with a disrupted pattern of photoreceptor recovery.

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°.
