BACKGROUND Evisceration is one of destructive surgery of eye after which a patient loses his hope of restoration of sight forever. AIM AND OBJECTIVES To identify the major causes of evisceration at a tertiary eye centre of Nepal. MATERIALS AND METHODS This is hospital based retrospective study of patients presented at Tilganga eye centre, Kathmandu, Nepal over a period of two years (10 Nov ...

BACKGROUND Intravitreal agents have replaced observation in macular edema in central (CRVO) and grid laser photocoagulation in branch retinal vein occlusion (BRVO). We conducted a systematic review to evaluate efficacy and safety outcomes of intravitreal therapies for macular edema in CRVO and BRVO. METHODS AND FINDINGS MEDLINE, Embase, and the Cochrane Library were systematically searched fo...

multiple topical agents for control of the intraocular pressure in her left eye. Analysis of Explanted NewColorIris Implant. Analysis using both light and scanning electron microscopy of one of the explanted NewColorIris devices shows surface and edge characteristics that deviate significantly from the appearance of other currently US Food and Drug Administration–approved anterior chamber impla...

A 58-year-old man admitted to our opthalmology department with the complaint of branch retinal vein occlusion. He was treated with intravitreal Ozurdex in the right eye. Two days after the injection, the patient presented with ocular pain and the visual acuity was hand movement. A diagnosis of endophthalmitis was made. We performed emergent pars plana vitrectomy (PPV) and the implant was remove...

We report live animal studies that verify and quantify successful transocular transmission of data from a miniature low-power implant. To minimize damage, implantation within layers of the eye requires an ultrasmall device on a scale of just a few millimeters on each side and less than 500 m in thickness. A high-frequency transmitter integrated circuit (IC) was designed, fabricated, and bonded ...

Purpose To demonstrate an unusual case of orbital trauma due to dental surgery complication. Observations An elderly patient who underwent dental implantation to the zygomatic bone was hospitalized in the ophthalmology department with impaired abduction of her right eye, also evident on ocular examination. Head computed tomography demonstrated damage to the lateral rectus and to the inferior ...

Intrastromal corneal inlays are an emerging treatment for presbyopic patients. The KAMRA™ small aperture inlay was the first such inlay to receive Conformité Européenne (CE) marking in 2005. It has been shown to improve uncorrected near and intermediate visual acuity without adversely affecting uncorrected distance visual acuity. Due to the age of presbyopic patients, they may eventually develo...

Osteo-Odonto-Keratoprosthesis (OOKP) or ‘Tooth-in-eye surgery’, the original technique was described by Benedetto Strampelli nearly fifty years ago, using the patient’s own tooth root and alveolar bone as vital support to an optical cylinder, for patients with the most severe type of corneal and ocular surface diseases, for whom other treatments would not be useful. The cornea is replaced by a ...

My guests in this corneal dissection column, John A. Hovanesian, MD, FACS, and Andrew Behesnilian, BS, describe their surgical technique of using amniotic membrane transplantation as a “biologic implant” beneath the normal conjunctiva surrounding the region where the pterygium is excised and replaced with a conjunctival autograft. They said the recurrence rate of 5% after pterygium surgery comb...

Electronic implants are able to restore some visual function in blind patients with hereditary retinal degenerations. Subretinal visual implants, such as the CE-approved Retina Implant Alpha IMS (Retina Implant AG, Reutlingen, Germany), sense light through the eye's optics and subsequently stimulate retinal bipolar cells via ∼1500 independent pixels to project visual signals to the brain. Becau...
