Corneal ectasia after laser in situ keratomileusis (LASIK) is a complicationcharacterised by progressive corneal thinning and bulging, which may lead to significant visual loss.While most patients who develop post-LASIK ectasia present identifiable risk factors, especially preoperative changes on corneal topography with a Placido disc, ectasia in patients with normal preoperative tests is still a mistery. 1,2 This editorial presents a new risk factor called Percentage ofTissue Altered,or PTA […].

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 […]

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.

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 […]

O cross-linking corneano é utilizado com o objetivo de reduzir e estabilizar a progressão das patologias ectásicas através de seus efeitos na biomecânica da córnea. Diferentes protocolos estão sendo realizados pelo mundo para expandir suas indicações, assim como seu uso em diversas faixas etárias, diferentes estágios da doença, combinações com outras técnicas, além de utilizações para doenças não ectásicas. Não há ainda um consenso nas indicações do procedimento de cross-linking, mas os resultados publicados na literatura evidenciam mudanças significativas nas […]
