The rise in preterm births and higher survival rates of premature infants have led to a global increase in retinopathy of prematurity (ROP), a vasoproliferative retinal disorder common in premature infants. ROP is one of the leading causes of childhood blindness. Clinical manifestation of ROP ranges from mild abnormal retinal neovascularization to bilateral retinal detachment and vision loss.

Purpose: To study functional changes in vision and morphological changes on optical coherence tomography (OCT) scans in patients where intravitreal therapy (IVT) with injections has been delayed due to COVID-19 pandemic lockdown.

Methods: Retrospective cross-sectional study included 77 eyes with the diagnosis of exudative age-related macular degeneration (eAMD), diabetic macular edema (DME), and retinal vein occlusion (RVO), regularly receiving IVT with anti-vascular endothelial growth factor (Anti-VEGF) injections or dexamethasone implant and were not able to receive the injections as intended due to lockdown. Best-corrected visual acuity (BCVA), central foveal thickness (CFT), and qualitative morphological features on OCT were analyzed pre- and post-therapy break off.

Retinopathy of prematurity (ROP) is the leading cause of preventable infant blindness in the world and predominantly affects babies who are born low birth weight and premature. India has the largest number of surviving preterm births born annually. ROP blindness can be largely prevented if there is a robust screening program which detects treatment requiring disease in time.

We aimed to evaluate the efficacy and safety of low-dose atropine compared to placebo in the Indian population and also to study the impact of various modifiable and non-modifiable factors on myopia progression (MP) and drug efficacy (DE). It was a single-centre prospective placebo-controlled interventional study. 43 participants aged 6-16 years with progressive myopia received 0.

Purpose: To assess the ability of wide field Swept Source OCTA (SS-OCTA) imaging to detect morphological variations in Serpiginous Choroiditis (SC) and Serpiginous Like Choroiditis (SLC) in response to treatment and also analyze these findings quantitatively using Image J software.

Methods: Retrospective observational case series of nine eyes with clinical diagnosis of active SC and SLC, who underwent SS-OCTA and fundus autofluorescence (FAF) imaging at baseline and each follow up visit till 6 months. Morphological analysis was done by two independent graders and quantitative analysis to measure the size and intensity of lesion was done using publicly available Image J software at baseline and each follow up visit.

Article Synopsis
  • The study investigates the connection between fetal oxidative stress and micronutrient deficiencies to the increased incidence of retinopathy of prematurity (ROP) in developing countries by analyzing blood samples from preterm infants.
  • It found that higher levels of malondialdehyde (MDA) in cord plasma and 40-week post-menstrual age samples were associated with ROP, while lower levels of copper, zinc, and vitamin A in maternal and cord samples were also significant.
  • The research concludes that increased oxidative stress and micronutrient deficiencies during fetal development contribute to the risk of ROP, highlighting the need for further investigation in this area.

The modern-day trocar cannula systems meant for adult eyes pose a challenge in infant's eyes with stage 4 retinopathy of prematurity (ROP) undergoing lens-sparing vitrectomy. This is primarily owing to the length of the trocar, globular lens, smaller axial length, and anteriorly displaced retina. We describe an inexpensive modification of the technique of trocar insertion in such cases wherein the trocar is inserted partially till the cannula impinges the sclera and thereon, the cannula slides over the trocar into the vitreous cavity.

Purpose: To study the complications and surgical outcomes of cataract surgery in patients of persistent fetal vasculature (PFV) with cataract.

Methods: In this prospective study, phacoaspiration with/without intraocular lens implantation (IOL) was done in 20 children (mean age 14.2 months) with unilateral cataract with anterior (n = 6) or combined (n = 14) PFV.

Purpose: Diagnosis of choroidal neovascular membrane (CNVM) is difficult in chronic central serous chorioretinopathy (CCSC) due to overlapping features of both on conventional dye angiography. Optical coherence tomography angiography (OCTA) allows a quick and noninvasive detection of CNVM in these eyes. We compared the fluorescein angiography (FA) features of CNVM with those of OCTA to assess the role of FA in detecting CNVM in CCSC eyes.

A 5-year-old girl presented with decreased vision and outward deviation of her right eye. Fundus examination revealed multiple hard exudates in the macula in the right eye and nasal to the disk in the left eye. The patient was lost to follow-up in the near term but presented 9 months later with reduced vision and an increase in exudates in both eyes.

Objective: To report the morphological spectrum and outcome after laser treatment in posterior zone I retinopathy of prematurity.

Design: Retrospective, consecutive, interventional case series.

Methods: Review of charts and RetCam images of preterm infants with posterior zone I retinopathy of prematurity (defined as area within a circle, the radius of which extends from the center of the optic disc to the center of the macula) treated with confluent laser at a tertiary care referral institute between January 2006 and December 2015.

Purpose: To report the change in incidence and severity of retinopathy of prematurity (ROP) in the neonatal unit of a tertiary hospital after a 20-year period.

Methods: A prospective cohort study of one-year duration was conducted between July 2013 and June 2014 in the neonatal intensive care unit (NICU) of a tertiary hospital. Inborn babies with birth weight ≤1700 g and gestational age ≤37 weeks were included.
