Background: Alopecia areata is a patchy hair loss that may occur in any hair bearing area on the body. There are many reports of ocular abnormalities such as lens and retinal changes in alopecia areata. Objective: To evaluate ocular alterations in alopecia areata with regard to the lens and retina. Patients & Methods: Seventy three patients with alopecia areata including 34 males and 39 f...

Ocular ultrasound is a relatively easy, noninvasive diagnostic modality to evaluate for ocular abnormalities and can be used as a complement to traditional ophthalmoscopic examination. Ocular ultrasound should be performed in horses with ocular trauma, disparity in ocular size or with any condition that impedes visualization of posterior ocular structures.

We previously found a dominant eye perceptional advantage in feature search (Vision Research, 2006). We now ask if this advantage extends to difficult conjunction search, which requires focused attention and depends on different cortical hierarchy levels. We determined eye dominance by the Hole-in-the-Card test. Using red-green glasses, subjects viewed a briefly presented, backward-masked, arra...

PURPOSE We assessed the potential ocular hazards of bright light therapy for patients with seasonal affective disorder, after both short- and long-term treatment, and identified prospective patients with pre-existing ocular abnormalities. METHODS Fifty patients with seasonal affective disorder received daily exposure to artificial light in the morning or evening for 30 minutes at an illuminan...

LEOPARD syndrome is an autosomal dominant hereditary disease, which is characterized with cutaneous pigmented patches, electrocardiographic changes, ocular hypertelorism, retarded growth, pulmonic stenosis, genital abnormalities and congenital deafness. The gene of this disease have high penetrance but expression is varied and incomplete forms may be seen. We report a 23 year-old woman wi...

Ocular movements were studied electro-oculographically in 10 normal subjects and 10 patients with alternating strabismus. Fixation and pursuit movements and to a less extent the saccadic movements were observed to be abnormal in patients with alternating strabismus. The defect in pursuit movements was shown to be statistically significant. There was no correlation between the extent of ocular m...

Eye movements were recorded and quantitatively analysed in a patient with a tumour initially involving the cerebellar flocculus. Ocular motor abnormalities included (1) impaired smooth pursuit, (2) impaired cancellation of the vestibulo-ocular reflex when fixating an object rotating with the head, and (3) gaze paretic and rebound nystagmus. Comparable findings have been reported in monkeys with...

purpose: to describe the variability of ocular and systemic findings in two brothers with gaucher's disease. case report: ophthalmic, general clinical evaluation and enzymatic studies were performed in two brothers, 14 and 7 years old with gaucher’s disease. mental retardation, occipital meningomyelocele and gaucher cells in bone marrow in addition to high myopia and various fundus abnorma...
