Oculocutaneous Albinism. A Case Report

SCIENTIFIC POSTER_Silvia Monteiro_1 Introduction: Oculocutaneous albinism (OCA) is a group of inherited disorders of melanin biosynthesis characterized by a generalized reduction in pigmentation of hair, skin and eyes. The prevalence of all forms of albinism varies considerably worldwide and has been estimated at approximately 1/17,000, suggesting that about 1 in 70 people carry a gene for OCA. The clinical spectrum of OCA ranges, with...

Surgical Treatment of the Macular Pathologies in Patients with Pigmentary Retinal Abiotrophy

SCIENTIFIC POSTER_Tatyana Kurskaya General considerations: At the moment there is no effective treatment for pigmentary retinal atrophy. The existing treatment methods of this genetic disease are aimed at maintaining of the declining eye visual functions and slowing down the optic nerve atrophy development. According to some authors (Shamshinova A.M., 2001; Fishman G., 1977) the macular changes in pigmented retinitis are observed in 63-74%...

The Changes of Choroidal Thickness in Adult Koreans

Purpose: To evaluate age-dependent changes of choroidal thickness in the Korean population. Method: One hundred and ten eyes of 65 patients were included in this randomized, prospective cross-sectional study. The choroid was imaged in all subjects using enhanced depth imaging (EDI) OCT (Cirrus, Zeiss). The choroid was measured subfoveally, 1000 µm temporal – 2000 µm temporally and 1000 µm nasal – 2000 µm nasally to the...

Thick, Adherent and Whitish Posterior Hyaloid: What is it?

RETINA PHOTO_Natalia Ferreira Few conditions are associated to thickening of posterior hyaloid membrane. Familial amyloidotic polyneuropathy (FAP) is characterized by systemic accumulation of mutant amyloigogenic transthyretin in different tissues, the eye included. FAP has peculiar ocular manifestations. Deposition of amyloid in vitreous cavity is a frequent one. Vitreous amyloid deposits (around collagen) are characteristic whitish and...

Choroidal Thickness Measurement in Myopic Eyes by Enhanced Depth OCT

Poster Vesta Cheuk Ki Chan Purpose: To measure choroidal thickness in myopic eyes using enhanced depth imaging in a cross-sectional study. Methods: Fifty-six consecutive patients with spherical equivalent refractive error of at least 6 dioptres were evaluated using enhanced depth imaging optical coherence tomography images that were obtained by positioning the spectral-domain optical coherence tomography (OCT) device close enough to the...
