We here in report the case of a patient subjected to cataract surgery through phacoemulsification under local anesthetic block, without intra-operative complications. The patient presented important visual impairment in the first post-operative day. Fundoscopy showed pallor resembling cherry-red spots at the macula. Fluorescein angiography did not depict signs of vascular occlusion and the spectral-domain optical coherence tomography showed increased reflectivity in the inner layers of the retina, thus suggesting local thickening and edema. The current case led to the diagnostic […]

Relatamos um caso de um paciente submetido a facectomia por facoemulsificação sob bloqueio anestésico peribulbar, sem intercorrências per-operatória, que apresentou no primeiro dia de pós-operatório baixa visual significativa. À fundoscopia observou-se palidez em aspecto de mácula em cereja. A angiofluoresceinografia não demonstrou sinais de oclusão vascular e a tomografia de coerência óptica mostrou aumento da refletividade das camadas internas da retina, sugerindo espessamento e edema local. No caso descrito foi aventada hipótese diagnóstica de oclusão arterial retiniana transitória.

Schnyder’s corneal dystrophy (SCD) is a rare corneal condition characterized by cholesterol and phospholipids deposition in the stroma and Bowman’s layer. We present a case report of a patient who had a progressive corneal stromal haze in both eyes since he was 15 years old. Etiological diagnosis of SCD was well established by In Vivo Confocal Microscopy (IVCM).

Tolosa-Hunt syndrome (STH) is a rare disease characterized by sudden onset unilateral painful ophthalmoplegia caused by non-specific granulomatous inflammation in the cavernous sinus or superior orbital fissure (or both). Ophthalmoparesis occurs when the cranial nerves III, IV and VI are affected by inflammation. Pupillary dysfunctions may be present and is related to involvement of the sympathetic fibers that pass through the cavernous sinus in the portion of the internal carotid artery or parasympathetic fibers around the oculomotor nerve. The involvement […]

The Ologen™ collagen matrix is a new antifibrotic agent composed of a porous matrix of type I atelocolagene and cross-linked glycosaminoglycans, which can be used as an alternative for the modulation of healing in surgeries. Because it is highly porous and biodegradable, this implant assists in the physiological repair processes that occur in the connective and epithelial tissue of the lesion without the formation of fibrotic tissue, which leads to surgical failure and IOP elevation. The Trabeculectomy (TREC) is considered […]

Objective: To evaluate the results of the surgical technique described by Crouch in the correction of lateral rectal paralysis (LR) esotropia. Methods: A study conducted of six patients with VI cranial nerve palsy, with more than three months, and associated contracture of the medial rectus muscle. The causes of paralysis varied in traumatic, congenital and neuropathic. The patients underwent surgical correction, performed with a technique consisting of the instillation of the superior rectus muscle (SR) and its suture above the […]

Objetivo: Avaliar resultados da técnica cirúrgica descrita por Crouch na correção de esotropia por paralisia do reto lateral (RL). Métodos: Estudo realizado com seis pacientes diagnosticados com paralisia de IV par craniano, com mais de três meses, e com contratura associada do musculo reto medial. As causas da paralisia variaram em traumática, congênita e neuropática. Os pacientes foram submetidos à correção cirúrgica, realizada com técnica que consiste na desinserção do músculo reto superior (RS) e sua sutura acima da inserção […]
