PURPOSE To characterize the morphology, prevalence, and topography of subretinal drusenoid deposits, a candidate histological correlate of reticular pseudodrusen, with reference to basal linear deposit (BlinD), a specific lesion of age-related macular degeneration, and to propose a biogenesis model for both lesion. METHODS Donor eyes with median death-to-preservation of 2:40 hours were postfi...

As the first case, a baby red eared slider turtle, Trachemys scripta elegans, 1.77 inches long, with a 4 month history of anorexia and blind eyes was referred to the Aquatic Animal Clinic, School of Veterinary Medicine, Shiraz University, Iran. The eyes of the pet were swollen and he was not active in swimming and feeling around. In the clinic, after stress treatment, he was kept in a clean aqu...

Background: A recently published, population based survey of the Tibet Autonomous Region (TAR) of China reported on low vision, blindness, and blinding conditions. This paper presents detailed findings from that survey regarding cataract, including prevalence, cataract surgical coverage, surgical outcome, and barriers to use of services. Methods: The Tibet Eye Care Assessment (TECA) was a preva...

PURPOSE To examine the relation between grating acuity at age 1 year and Snellen acuity and grating acuity at 5.5 years, in preterm children with birth weights less than 1251 g. METHODS Subjects were participants in the multicenter study of Cryotherapy for Retinopathy of Prematurity. The Teller acuity card (TAC; Vistech Consultants, Dayton, OH) procedure was used to measure monocular grating ...

The objective of this study is to investigate the characteristics and the evolution of visual field damage caused by Leber's hereditary optic neuropathy (LHON) and to provide clinical data for the diagnosis of LHON. Parameters of visual field in 32 consecutive patients (49 eyes) with LHON who were confirmed by genetic diagnostic tests were retrospectively measured within 1 week, between three t...

Three systems affect the upright standing posture in humans - visual, vestibular, and somatosensory. It is well known that the visually impaired individuals have bad postural balance. On the other hand, it is a well documented fact that some sports can improve postural balance. Therefore, it is aimed in this study to evaluate the dynamic postural stability in goal-ball athletes. Twenty blind go...

BACKGROUND In order to evaluate the effect of an auditory-memory attention-demanding task on balance control, nine blind adults were compared to nine age-gender-matched sighted controls. This issue is particularly relevant for the blind population in which functional assessment of postural control has to be revealed through "real life" motor and cognitive function. The study aimed to explore wh...

The results of a 12-month blind randomised trial comparing the intraocular pressure lowering effect of timolol 0.25% with timolol 0.5% are presented. 27% of patients (22% of eyes) required additional antiglaucoma medication after a minimum time interval of 6 months to maintain an intraocular pressure less than 23 mmHg. The mean reduction in intraocular pressure (from pretreatment values) at 12 ...

For humans, caves are dark, moist, and often dangerous places. However, also home to many animals that live strange lives: blind beetles eat bat poop appreciate it; tiny spiders spin webs catch insects, known as flying food; white salamanders swim in cave ponds without getting lost, at least not all the time. Most of these do have eyes—why would you need eyes when dark? Instead, they developed ...
