What are cavefish? Like other cave-dwelling animals, fish that live in caves have often lost their eyes and body colour, but the evolutionary mechanisms underlying these reductions are unknown. There are 86 species of cavefish that belong to 18 different families, and many of them have lost their eyes independently. Comparing cavefish to their free-living ancestors can thus help us understand c...

The multi-fixation glaucoma screening chart, which uses the oculokinetic perimetry (OKP) technique, is a hand-held tangent screen with a central black test stimulus on a white background and a series of 26 numbered fixation targets arranged around the stimulus at various locations. When the numbers on the chart are read by the patient from 40 cm distance, the test stimulus passes through the re...

AIMS To assess the effectiveness of enucleation or evisceration in relieving pain from painful blind eyes. METHODS 24 patients with intractable ocular pain underwent enucleation or evisceration with or without an orbital implant. RESULTS Complete pain relief was achieved in all patients at an average time of 3 months (range 1-15 months). Seven patients required further medical or surgical t...

Pediatric ocular trauma is a commonly seen in patients with maxillofacial trauma.[1] It often results in phthisis bulbi, a small, shrunken, non-functional eye. Therapeutic options are limited in phthisical eyes and provide only symptomatic relief. Majority of patients with phthisis bulbi eventually become blind resulting in aesthetic disfigurement of face resulting in psychological and emotiona...

A 7-year-old boy had an unusual association of median cleft-face syndrome, a characteristic physiognomy, unilateral retinal dysplasia, and bilateral retinal detachment. Despite surgical treatment to both eyes he became blind. The hereditary pattern operating in this complex disorder was found to be consistent with an autosomal dominant trait.

A total of 466 leprosy patients in Nepal, some advanced cases, were surveyed for ocular lesions. 74.2% were found with ocular features, and 12.7% of the eyes were blind. The patients were classified in tuberculoid, borderline-borderline, and lepromatous groups. Lepromatous leprosy is responsible for major ocular complications and blindness.

Microcenoscelis n. gen. (Coleoptera: Tenebrionidae: Ulomini) caeca n. sp. is described from Zimbabwe, a small and completely blind species. A second known species, however with completely developed eyes, and originally described as Uloma minuscula Ardoin, 1969, was also placed in the new genus. Microcenoscelis n. gen. seems to be mostly related to the genera Cenoscelis Wollaston, 1867, and Cneo...

Short stories as part of the literature play a significant role in portraying human lifestyle, including image disabilities. Studying portrayal disabled people becomes to consider need change illustration disabilities fiction. There are four short selected this study, namely “Cathedral” By Raymond Carver, “The Blind Man” by Guy de Maupassant, Kate Chopin and “A Man Who Had No Eyes” Benjamin Mac...

purpose: to report a case of spinal cord tumor with visual symptoms and papilledema due to increased intracranial pressure. patient and findings: a 24-year-old woman was referred because of recent blurred vision in both eyes. visual acuity was 20/25 and 20/20 in the right and left eyes, respectively. fundoscopy revealed bilateral papilledema. other ophthalmic examinations were normal. visual fi...

PURPOSE To visually perceive our surroundings we constantly move our eyes and focus on particular details, and then integrate them into a combined whole. Current visual rehabilitation methods, both invasive, like bionic-eyes and non-invasive, like Sensory Substitution Devices (SSDs), down-sample visual stimuli into low-resolution images. Zooming-in to sub-parts of the scene could potentially im...
