Mohr-Tranebjærg syndrome (MTS) is an X-liked recessive rare syndrome also known as deafness-dystonia syndrome. The severity of the symptoms may vary, but they progress usually to severe deafness and dystonia and sometimes they are accompanied by cortical deterioration of vision and mental deterioration. The purpose of this paper is to illustrate a very interesting case of Mohr-Tranebjærg syndrome. A 24-year-old italian man with Mohr-Tranebjærg syndrome underwent full field electroretinography (ERG) and visual evoked potentials (VEPs). Fundus examination showed apparently normal […]

A síndrome de Mohr-Tranebjærg é rara, com herança recessiva ligada ao X, conhecida também como síndrome da surdez-distonia. A intensidade dos sintomas pode variar e normalmente, evoluem para uma surdez profunda e a distonia, algumas vezes, vem acompanhados por deterioração visual e mental. O objetivo deste trabalho é ilustrar um caso muito interessante dessa doença. Um homem, italiano, de 24 anos, com a síndrome de Mohr-Tranebjærg, foi submetido ao exame de eletrorretinografia de campo total (ERG) e ao exame de […]

High astigmatism correction represents a challenge for the refractive surgeon with current available technology. Excimer laser correction should be considered as an option in the available therapeutic arsenal. We report a patient with astigmatism higher than eight diopters to whom it was used a treatment with LASIK (Laser Assisted In Situ Keratomileusis) in two surgical moments, using a new generation of excimer laser with an optimized aspheric profile.

Granulomatous polyangiitis is a systemic disease that may affect any organ, with a predilection for the upper respiratory tract, lungs and kidneys. This article aims to report a case of a patient with atypical nodular scleritis as the initial manifestation of granulomatous polyangiitis (Wegener), mimicking a case of tuberculosis. The patient presented ocular hyperemia and lower progressive visual acuity for 1.5 years, followed by eye pain for two months. The patient had subpleural nodules with soft tissue density, increased pulmonary […]

Revesz syndrome is a rare variant of dyskeratosis congenita and is characterized by bilateral exudative retinopathy, alterations in the anterior ocular segment, intrauterine growth retardation, fine sparse hair, reticulate skin pigmentation, bone marrow failure, cerebral calcification, cerebellar hypoplasia and psychomotor retardation. Few patients with this syndrome have been reported, and significant clinical variations exist among patients. This report describes the first Brazilian case of Revesz syndrome and its ocular and clinical features.

A síndrome de Revesz é uma rara variante de disceratose congênita caracterizada por retinopatia exsudativa bilateral, alterações no segmento anterior ocular, retardo do crescimento intrauterino, pilificação fina e escassa, pigmentação cutânea reticular, falência da medula óssea, calcificações cerebrais, hipoplasia cerebelar e retardo neuropsicomotor. Há variações clínicas significativas entre os poucos relatos desta patologia existentes na literatura. Descrevemos o primeiro caso brasileiro de síndrome Revesz e suas características clínicas e oculares.

Macular cystoid edema is one of the major causes of decreased vision after cataract surgery. The inflammatory process appears to be the main causal factor of the edema. The major risk factors are: surgical complications, previous retinal diseases, diabetes, uveitis and use of prostaglandins drops. The diagnosis is clinically, but fluorescein angiography and optical coherence tomography are also important to detect swelling and assist in differential diagnosis. Although pre-operative prophylaxis do not have scientific evidence, it is recommended especially in […]

The corneal cross-linking has been used in order to reduce and stabilize the progression of ectatic diseases through its effects on the biomechanics of the cornea. Different protocols are being conducted worldwide to expand its indications as well as its use at different ages, different stages of the disease, combinations with other techniques, besides the utilization for non-ectatic diseases. There is still no consensus on the indications of the cross-linking procedure, but the results published in the literature show significant […]
