INTRODUCTION Pars plana vitrectomy as a technique has revolutionized retinal surgery since its advent and initial report by Machemer et al 1. It allowed the removal of traction by an internal method, essential in retinal detachment procedures, as well as provided an active management modality for vitreous haemorrhage and opened the door for surgical intervention in a myriad of retinal pathologies....Read More

Chemical Injuries of Eye - An Update.
Introduction It is very frequent to encounter chemical injury in our routine ophthalmic practice. Most of the chemical injuries are minor, which heal without any squeal. Most are acids and alkalis. Alkali injuries are more common (nearly twice) than acids and are more severe in nature. It is of utmost importance to recognize the nature of chemicals for treating such patients. Here, we review the c...Read More
Proliferative Diabetic Retinopathy
Diabetic retinopathy (DR) is the leading cause of visual impairment worldwide. It almost accounts for 2.6% of treatable blindness globally (1). It is estimated that the overall prevalence of diabetic retinopathy is 34.6 % worldwide, while the prevalence of proliferative diabetic retinopathy (PDR) is 6.96% and that of vision-threatening DR (VTDR) is computed to be 10.2% (2). Currently, the prevalen...Read More
Lensopedia: Lenses in Ophthalmology
Introduction: While there are several instruments in ophthalmological practice, lenses form an inseparable part of an ophthalmologist’s arsenal. Available in various sizes and shapes, they are crucial in aiding the visualization of remote areas of the eye and facilitate therapeutic interventions in those areas which would be next to impossible to even imagine without their availability. Harnessing...Read More
Introduction First described in 1942, retinopathy of prematurity (ROP) is a vasoproliferative retinopathy affecting premature infants of low birth weight. As per the original description by Terry et al, this disease was labelled as retrolental fibroplasia (RLF) based on the hypothesis that it involved the proliferation of the embryonic hyaloid system[1] But Owens and Owens later described that in ...Read More
LASERs in Ophthalmology: A Concise Guide for the Postgraduates
LASER is an acronym for “light amplification by stimulated emission of radiation”. Invented more than 50 years ago, today lasers are synonymous with precision and sophistication. The first medical application of lasers was the use in retinal photocoagulation and that role has been ever-evolving. Today its application is evident in all subspecialties of ophthalmology as a diagnostic and therapeutic...Read More
Introduction: Macular edema is defined as swelling of the layers of neurosensory retina within the macula. Cystoid macular edema (CME) is a subtype of macular edema characterized by extracellular accumulation of fluid within the outer plexiform layer of the retina in the form of intraretinal cyst. It is known as one of the complications, that develops consequent to a final common pathway in divers...Read More
Polypoidal Choroidal Vasculopathy
Introduction Polypoidal Choroidal Vasculopathy (PCV), first described by Yannuzzi et al1 in 1982, is a distinct clinical entity characterized by persistent recurrent serous leakage and hemorrhage in the macula, and is seen in the elderly population. The disorder was poorly understood earlier and had been described by various authors as recurrent pigment epithelial detachment (PED) and posterior uv...Read More
Drug Induced Maculopathy: A Quick Look
Generally all the drugs are likely to have some side effects. For ophthalmologists, it is essential to know the drugs which affect the vision or involve the eye as a part of their side-effects. This is a summary of the drugs causing damage to the posterior segment of the eye. Patterns of retinal toxicity: Disruption of the retina and retinal pigment epithelium Vascular damage Retinal folds Phenoit...Read More
Introduction History In 1908 George Coats1 original description of the disease was based primarily on histopathologic examination of enucleated eyes and identified retinal vascular aneurysms, arteriovenous malformations, intra- and subretinal hemorrhages, and exudates. Coats categorized eyes with these characteristic morphologic findings into three groups: Group I demonstrated massive subretinal e...Read More
