Povidone Iodine: Use in Ophthalmology
Povidone-iodine (PVI) is a disinfectant and antiseptic agent used for preoperative preparation of the skin and mucous membranes due to its broad spectrum of microbicidal activity. Preparation of the eyelids, eyelashes, and conjunctiva prior to intraocular surgery, decrease the risk of endophthalmitis [1]. PVI is composed of diatomic iodine and polyvinylpyrrolidone (povidone). Povidone is a […]
Ultra-Wide Field Non Mydriatic Retinal Imaging System
Assessment of peripheral retina is essential for diagnosis of various retinal diseases and their subsequent management and follow up. Conventionally, this was possible in past only with the help of Indirect Ophthalmoscopy (IDO) with the possibility of inter observer variability. For documentation, the traditional ETDRS seven standard field (SSF) imaging includes the central posterior 90° […]
Drug Abuse and Endophthalmitis
A U.S based study suggests a “high degree of suspicion” in patients with drug abuse leading to endogenous endophthalmitis as high as up to four folds, especially to recent trend of consuming intravenous opiates such as heroin. The morbidity and mortality rates from endogenous endophthalmitis worsens more with comorbidities like diabetes, malignancy, chronic kidney disease, Chronic […]
Trifocal-Lens Implant: A Spectacle Free Life
As per a Survey, Eighty percent of patients implanted with trifocal intraocular lenses(IOLs) never require spectacles as compared to one with monofocal IOLs( only 8%). Most patients require glasses after cataract surgery with monofocal IOL implantation and even multifocals affects contrast sensitivity with increased photic phenomena. The TFNTOO (Panoptix, Alcon, Fort Worth, TX) is the only […]
An Arrow in the Quiver: 3D Cataract Surgery
The 3-D assisted vitreoretinal surgeries(N Genuity, Alcon)(Artveo 300, Zeiss) are in the news now for quite a while but the 3-D anterior segment procedures, yet, need some more futuristic considerations. There are certainly some obstacles to the use of simple microscope like: Microscope must be moved everytime for better visualisation, which makes it out of […]
“Durysta” Extended Release Bimatoprost Implant
The US Food and Drug Administration approved Allergan’s bimatoprost implant (Durysta) in March 2020, with a cost of around $1000. The bimatoprost implant, holds drug in a solid polymer matrix, biodegrades over time and maintained IOP as consistently as timolol maleate eye drops administered regularly at for at least 6 months, delivered better results as […]
Eye and Parkinson’s Disease
Parkinson’s disease can only be recognized once 80% of dopaminergic cells in the brain has degenerated and there is no biomarker for its diagnosis and no clinical method to diagnose its duration. A simple fundus examination of the eye studying the eye vasculature- the arrangement of vessels can promisingly detect Parkinson’s disease in early stage- […]

Management of a Case of Post Traumatic Chronic Cyclodialysis Cleft With Hypotony Using Sewing Machine Technique. A 38 year old male presented to us with h/o blunt trauma to the eye with shuttle cock 3 months back, BCVA – RE 6/36 n36, LE 6/6 n6, IOP – RE 6 mm of Hg, LE 18 mm of Hg. […]
Smartphone-Based Gonio-Imaging Device
Introduction: The ophthalmic imaging has now revolutionized with the deployment of smartphone for the image acquisition. The widespread adaptability is due to multiple factors, the forefront of which are the availability of good resolution cameras in mid and high-end smartphones, good auto-focusing mechanism, in-built high capacity storage, internet capabilities that enable cloud storage and teleconsultation […]
