Marfan syndrome (MFS) is a genetic disorder which is inherited by autosomal dominant traits. In MFS, lens displacement and cardiovascular involvement are important causes of morbidity and mortality in the clinical course of the disease. In this case study, the ocular involvement in a family with severe penetration of MFS is reported. Twelve members of a family (father, two daughters, three sons...

after central nervous system (cns) injuries, the regeneration process does not work out well except for remyelination process. this remyelination capacity in cns can be mentioned as a worthy example of stem/precursor cell-mediated renewal process. remyelination in cns is mediated by schwann cells which act mainly as remyelinating agents in peripheral nervous system (pns) but several studies hav...

background: headache is one of the most disturbing symptoms with common neurological signs. variations in optic nerve perfusion quality or retinal microcirculation may end up in ganglion cell damage in patients with migraine. methods: sixty patients diagnosed with migraine and thirty normal individuals were evaluated in groups including migraine with aura, migraine without aura and controls. re...

Background: Retinal G-protein–coupled receptor opsin (RGR) functions as a photoisomerase that convert the all-trans-retinal to 11-cis-retinal in human retinal pigmented epithelium. Our research and others have demonstrated opsin-based UVR phototransduction system existed skin. However, whether RGR is expressed skin has not yet been identified. Objective: To determine expression, distribution su...

The morphology of retinal photoreceptor layer was studied in continuous light-exposed and dark-adapteddomestic male cats (Felis catus). The eyes of 12 healthy adult cats (4 in continuous light-exposed group, 4 in continuous dark-adapted group, and 4 in control group) were routinely fixed and studied by electron microscope. Results showed that the general structure of photoreceptor layer in this...

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...

Aim The aim of this study is to compare the choroidal, retinal, and peripapillary nerve fiber layer thickness patients diagnosed with hyperthyroidism but did not develop ophthalmopathy euthyroid patients.
 Material Methods: Thyroid stimulating hormone (TSH), freeT3 (fT3) freeT4 (fT4) tests were analyzed. Cases who came in symptoms had a TSH lower than 0.5 mu/L included study. Retinal (RT),...

Central Retinal Artery Occlusion (CRAO) is the partial or complete blockage of central retinal artery presenting as acute painless monocular vision loss with increased risk in those cardiovascular disease. Diagnosis CRAO requires a dilated fundoscopic exam performed by an Ophthalmologist. In resource limited hospitals, access to these expertise and resources may be difficult.
