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

“With great power comes great responsibility” Stan Lee in Spiderman Introduction: Publications represent the three ‘R’s of modern times– recognition, respect, and revenue, for anyone in the field of science and research. Authorship has become the currency of the current generation and a measure of one's status in the international scientific community. The number of papers published, the journ...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
The Effects & Techniques of Scleral Buckle in Treatment of Retinal Detachment
Introduction: Scleral buckle surgery is indicated for uncomplicated rhegmatogenous retinal detachments. Scleral buckling indents the sclera and the overlying choroid retinal pigment epithelium complex towards the retinal break in the detached retina, resulting in retinal reattachment. Scleral buckle surgery evolved out of the works of Jules Gonin, who identified retinal breaks as the cause of reti...Read More
Acanthamoeba Keratitis: A review for the Postgraduates
Eye diseases affecting the cornea are a major cause of blindness worldwide. Among different infectious agents, bacteria, fungi, viruses and protozoans may be causes of keratitis. This article is about the keratitis caused by protozoa. Three amoebic parasites are thought to be significant to human disease, entamoeba which is responsible for amoebic dysenter, naegleria which causes amoebic meningoen...Read More
WHO (ICD-10) defines low vision as “A person who has impairment of visual functioning even after treatment and/ or standard refractive correction, and has a visual acuity of less than 6/18 to light perception, or a visual field less than 10 degrees from the point of fixation, but who uses, or is potentially able to use, vision for the planning and/ or execution of a task for which vision is essent...Read More
Introduction Optical Coherence Tomography is a powerful noninvasive imaging modality that performs high resolution, micron-scale, cross-sectional imaging of the retina. Originally developed in 1991 by Huang et al, [1] OCT technology has continually evolved and expanded within ophthalmology and has been explored in a wide range of clinical applications. With the introduction of Spectral/ Fourier Do...Read More
Refraction Simplified for the Post Graduates
The optics of the eye normally creates a clear image by refracting rays of light to focus on the retina. Imperfections in this optical system create aberrations and thus blurred images. The goal is to analyze them and devise a means to eliminate them. Lower order aberrations are primarily refractive errors when parallel rays of light after refracting, do not focus on the retina with accommodation ...Read More
