Choriocapillaris Flow Deficits Quantification in Hydroxychloroquine Retinopathy Using Swept-Source Optical Coherence Tomography Angiography.

This study aims to quantitatively analyze choriocapillaris (CC) alterations using swept-source optical coherence tomography angiography (SS-OCTA) in eyes presenting with hydroxychloroquine (HCQ) toxic retinopathy and to compare it to patients under HCQ without toxic retinopathy and to healthy controls. For image analysis, CC en-face slabs were extracted from macular 6 × 6 mm SS-OCTA scans and a compensation method followed by the Phansalkar local thresholding was performed. Percentage of flow deficits (FD%) and other related biomarkers were computed for comparison.

[Partial thrombosis of the corpus cavernosum: A new case with good outcomes under non-steroidal anti-inflammatory drugs].

Partial priapism is a rare pathology with less than 60 cases published in the literature; the etiology remains unknown, although certain favorable factors are identified as having in relation a prolonged perineal compression or a thrombopathy. The symptomatology is characterized by the appearance of pain, perineal edema and an induration of the root of the penis, which do not concern the distal part of the penis or the glans. MRI is the best complementary examination.
