Comparative Study
Assessment of blood flow velocity in eyeball arteries in multiple sclerosis patients with past retrobulbar optic neuritis in color Doppler ultrasonography.
The aim of the study was to evaluate blood flow velocity in eyeball arteries in affected and unaffected eyes in patients with past retrobulbar optic neuritis in the course of multiple sclerosis (MS). ⋯ In MS patients with past optic neuritis disturbances of ocular circulation can be observed. The statistically significant diminishing blood flow velocity parameters and vascular resistance indices in eyeball arteries may indicate alterations of blood flow. Lowering of systolic and mean velocities and resistance indices of blood flow are most expressed in CRA and SPCA. Reduction in blood flow parameters in the examined arteries occur both, in the eyes previously affected by past optic neuritis and in contra lateral, unaffected eyes.

We report case of acute retinal pigment epithelitis (ARPE), a very rare ophthalmic disorder, which has a very good final visual prognosis. The 18 years old woman was examined by ophthalmologist for sudden visual decrease of vision and dark spot in visual field of her left eye. The best corrected visual acuity (BCVA) of the left eye at the initial diagnosis was 0.1 and after 4 months improved to 0.9. The diagnosis or ARPE was made on the basis of fundoscopy, fluorescein angiography, electroretinography and optical coherence tomography (OCT) examination.

Diabetic visual complications prevention relies, on the one hand, on an intensive metabolic control of diabetes and elimination of coexisting risk factors for development of diabetic retinopathy and, on the other hand on carrying out a programme for early detection and treatment of diabetic retinopathy. Proper treatment of diabetes, expressed by good glycaemia control, proper arterial pressure parameters and lipid concentration in blood reduce the risk of heavy complications and extends life span and improves its quality. ⋯ Examination of the eye fundus completed with fluorescein angiography make a golden standard in retinopathy diagnosis and classification. The incidence of vision loss due to diabetes is significantly lower in the countries which introduced programs preventing retinopathy than in those which do not have them.

The aim of the study is to evaluate the dynamics of axial elongation of pseudophakic eyes and changes in refraction pseudophakic eyes in children after monocular or binocular cataract surgery. ⋯ The dynamics of axial elongation of pseudophakic and phakic eyes in children is similar. The myopic shift of pseufophakic eyes is bigger than in phakic eyes. It should be undertaken in calculation of the refractive power of intraocular lenses.

Giant cell arteritis is a rare systemic vasculitis affecting large- and medium-sized arteries. Focal arteries lesions, include mononuclear cells infiltration of the vessel wall with giant cell formation. It is a disease of elderly persons and can result in a wide variety of systemic, neurological and ophthalmic complications, due to ischemia. ⋯ The other ocular ischemic lesions include: central retinal artery occlusion, choroidal ischemia, diplopia, ocular motor paresis, anterior uveitis, cataract, ocular hypotony, corneal oedema and ulcerations, episcleritis and anterior scleritis, orbital cellulitis and pseudotumor. Because giant cell arteritis is potentially blinding disease, early diagnosis and immediate treatment with high dose corticosteroids may prevent further damage to the affected eye and prevent visual loss in the opposite eye. The purpose of this review is to revise established knowledge and to highlight the recent developments in diagnosis and management of giant cell arteritis.
