Pseudophakic Cystoid Macular Edema
Pseudophakic cystoid macular edema (PCME) is a common cause of visual impairment after cataract surgery. This article systematically reviews and discusses the epidemiology, risk factors, diagnosis, and treatment of PCME, with a focus on advances in the past 1–2 years.In 1953, Irvine described a cystoid macular edema (CME) that specifically arised after cataract surgery.1 Gass and Norton subsequent...Read More
Management of Rhegmatogenous Retinal detachments- Evidence based Review
Introduction Rhegmatogenous retinal detachment (RRD) although rare, it is a serious ophthalmic condition that can lead to significant loss of vision or blindness without timely and appropriate management. It has been nearly a century (1918) since Jules Gonin demonstrated the importance of localizing and sealing retinal breaks, a procedure termed ignipuncture.1 Scleral buckling techniques, introduc...Read More
Retinal vasculitis is an inflammatory disease of the blood vessels of the retina that may be associated with primary ocular conditions or with inflammatory or infectious diseases in other parts of the body (systemic diseases). It has been defined as the vascular leakage and staining of vessel walls on fluorescein angiography, with or without the clinical appearance of fluffy, white perivascular in...Read More
Serpiginous Choroiditis: An Update
The word “serpiginous” is an adjective which means “with a wavy or indented margin”. The serpiginous choroiditis shows the similar wavy or amoeboid like lesions in choroid as a result of inflammation of unknown aetiology. The serpiginous choroiditis may be defined as a chronic, progressive, usually bilateral, recurrent in?ammatory condition which affects the choroid, choriocapillaries and retinal ...Read More
Ocular Histopathology: A ready reckoner
Basic histology of the eye Eyelid: Each eyelid consists of skin, subcutaneous tissue, striated muscle fibers of orbicularis oculi, orbital septum and tarsal plates, smooth muscle and conjunctiva. The skin contains sebaceous glands and small sweat glands.The eyelashes are more numerous in the uppereyelid than in the lower. The sebaceous glands of Zeis open into each follicle. Histological photograp...Read More
Retinablastoma:The current concepts
Introduction Retinoblastoma is the most common intraocular malignancy in children, with a reported incidence ranging from 1 in 15,000 to 1 in 18,000 live births.1 It is second only to uveal melanoma in the frequency of occurrence of malignant intraocular tumors. There is no racial or gender predisposition in the incidence of retinoblastoma. Retinoblastoma is bilateral in about 25 to 35% of cases. ...Read More
OCT in Age Related Macular Degeneration (ARMD) and Polypoidal Choroidal Vasculopathy (PCV)
Optical Coherence tomography (OCT) has revolutionized the way we look at retinal disorders. The earliest version of OCT was the time domain OCT following which spectral domain OCT arrived. Advances such as enhanced depth imaging and swept source OCT have furthered our understanding of retinal disorders. Beginning from the early 90s , OCT has vastly improved the way we diagnose, prognosticate , tre...Read More
Advanced Custom Ablation: New Technology for Better Quality of Vision
LASIK is the most widely used technology for the correction of most spherocylindrical ametropias because of its safety and its predictability that leads to excellent outcomes for both the patient and the surgeon. Over the years there has been a progressive refinement of the technique. Customised correction of refractive errors using wavefront technology has revolutionised the way we plan and execu...Read More
Acute retinal necrosis was first described in Japan by Urayama and colleagues who described six otherwise healthy patients, presented with panuveitis and retinal arteritis developing retinal detachment. At that point of time, this entity was known in the Japanese literature as “Kirisawa uveitis”1.Young and Bird first used the term “bilateral acute retinal necrosis” in 1978 2. In 1982 Culbertson an...Read More
Diabetic maculopathy is the most common cause of visual impairment in patients with diabetes mellitus. Classification Diabetic maculopathy is classified as – Exudative Maculopathy Ischemic Maculopathy Mixed Maculopathy 1. Exudative Maculopathy (Diabetic Macular Edema) It is diagnosed stereoscopically as retinal thickening within 1 disc diameter of the center of the macula using fundus biomicroscop...Read More
