Microscopic polyangiitis is a rare autoimmune disease of unknown etiology, characterized by inflammation and necrosis of blood vessels. It forms a part of the antineutrophil cytoplasmic antibody-associated vasculitides-a heterogeneous group of disorders characterized by vasculitis. It is a systemic disease affecting multiple organs.

We describe a case report of a spontaneous suprachoroidal hemorrhage, in which the enhanced depth imaging optical coherence tomography (OCT-EDI) is extremely useful in establish the differential diagnosis with a choroidal tumor. A 70 year-old woman was referred with a central scotoma after a Valsalva maneuver. In the posterior pole we observed a grey bilobed subretinal mass with the appearance of a choroidal tumor.

Objective: The objective of this study was to analyse the results of the surgical treatment of coexisting cataract and glaucoma and its effects on corneal endothelial cell density (CECD).

Methods: We include two longitudinal prospective studies: one randomised that included 40 eyes with open angle glaucoma that received one- (n = 20) or two-step (n = 20) phacotrabeculectomy and another that included 20 eyes that received phacoemulsification. We assess the impact of surgery on different clinical variables and in particular in CECD using Confoscan 4™ confocal microscopy and semiautomatic counting methods.

Introduction: The most distinctive patterns of posterior pole affectation in syphilitic patients are acute posterior placoid chorioretinitis (ASPPC), pseudoretinitis pigmentosa and panuveitis with white focal preretinal opacities. However, outer retinitis is not a common presenting feature in this disease.

Case Report: Thus, we report an atypical case of syphilitic outer retinitis (SOR) and severe retinal phlebitis as presenting manifestations in a patient with HIV and syphilis coinfection.

Purpose: To determinate the variation in thickness of the individual choroidal layers in patients with central serous chorioretinopathy treated with half-fluence photodynamic therapy.

Methods: Twenty-two eyes were evaluated with spectral-domain optical coherence tomography. The images were taken before photodynamic therapy, 3 months, and 6 months after the treatment.
