Retinopathy of prematurity - Intersibling divergence of risk factors among twins

Published on: 19th February, 2020

Retinopathy of prematurity (ROP) is a consequence of an arrest in normal retinal neural and vascular development, which determines the aberrant retinal regeneration [1,2]. ROP is a disease process mostly reported in preterm neonates ranging from mild, transient changes in the retina with regression to severe progressive vasoproliferation, scarring, detachment of retina and blindness and it is common blinding disease in children and a major cause of vision loss among preterm infants [3]. Today it is well known that oxygen therapy is not the single causative factor, but many other risk factors play a causative role in the pathogenesis of ROP [4,5]. The risk factors for ROP include oxygen administration, hypoxia, hypercapnia, blood transfusion exchange transfusion, apnea,sepsis and total parenteral nutrition. The incidence of ROP has been reported to be similar in multiple and singleton births [6-8]. Twin studies show that from 70% to 80% of the susceptibility to ROP is conditioned by genetic factors [9,10]. Hence this study is to find out the incidence of ROP in twins in a tertiary care centre in a developing country. It also attempts to identify the difference in risk factors among twins which predispose to ROP in Neonatal Intensive Care Unit.

Two different patterns and outcome of neodymium YAG capsulotomy

Visual impairment is a global health problem. Cataract is responsible for 50% of blindness worldwide [1]. Posterior capsular opacification is the most common late complication of cataract surgery as a result of proliferation of residual lens epithelial cells overall 25% of patients undergoing extra-capsular cataract surgery develops visually significant PCO within 5 years of the operation [2]. Nd: YAG laser provides the advantage of cutting the posterior lens capsule, thereby avoiding and minimizing infection, wound leaks, and other complication of intraocular surgery. Thus Nd:YAG laser capsulotomy is noninvasive, effective and relatively safe technique [3]. However, this procedure is associated with complications such as- postoperative increased intraocular pressure (IOP), cystoid macular edema (CME), disruption of the anterior vitreous surface, uveitis, lens subluxation, increased incidence of retinal detachment and pitting of the IOL [4]. Laser shots can be applied in several patterns such as “Cruciate or Cross pattern”, “Can opener”, inverted “U-Method” and in a “Circular pattern”. Many authors promote the use of a cruciate pattern in the Centre of the visual axis, with the clinician starting off on both axes away from the Centre to avoid pitting the lens centrally [5]. This study mainly aims to analyze the effect of various forms of PCO capsulotomy openings on visual function after Nd: YAG capsulotomy.
