Racemose hemangioma presenting as a vitreous hemorrhage: case report

Rev. bras. oftalmol; 82 (), 2023
ABSTRACT This report describes a case of retinal racemose hemangioma that first presented as a vitreous hemorrhage. The authors present the case of a 47-year-old woman with a sudden 5-day painless visual loss in her left eye. At the first visit, the best-correct visual acuities were 20/20 in the right ey...

Fractal evaluation in retinographies of individuals with different grades of diabetic retinopathy

Rev. bras. oftalmol; 81 (), 2022
ABSTRACT Purpose To evaluate the retinal blood vascular network of the retinographies of patients with different grades of diabetic retinopathy. Methods Ninety Retinographies (MESSIDOR database) were used, with different grades of diabetic retinopathy divided into 4 groups: no retinopathy (n=23), gra...

Optical coherence tomography angiography: microvascular alterations in diabetic eyes without diabetic retinopathy

Arq. bras. oftalmol; 84 (2), 2021
ABSTRACT Purpose: To describe microvascular changes in the maculas of individuals with type 2 diabetes observed on optical coherence tomography angiography (OCTA) images. We compared the maculas of diabetic subjects without diabetic retinopathy with those of healthy subjects and correlated the findings ...

Evaluation of retinal and choroidal microvascular changes in patients who received hydroxychloroquine by optical coherence tomography angiography

Arq. bras. oftalmol; 84 (1), 2021
ABSTRACT Purpose: The aim of the study is to evaluate the retinal and choroidal microvascular changes via optical coherence tomography angiography in patients who received hydroxy­chloroquine. Methods: In total, 28 eyes of 28 patients (24 females, and 4 males) receiving treatment with hydroxy­chloroq...

Association between disorganization of the retinal inner layers and capillary nonperfusion area in patients with retinal vein occlusion

Arq. bras. oftalmol; 83 (6), 2020
ABSTRACT Purpose: To determine the correlation between the extent of disorganization of the retinal inner layers (a parameter of spectral domain optical coherence tomography) and optical coherence tomography angiography parameters in eyes with center-involved macular edema associated with retinal vein o...

Evaluation of the retinal vasculature of patients with branch retinal vein occlusion using optical coherence tomography angiography

Arq. bras. oftalmol; 83 (6), 2020
ABSTRACT Purpose: To evaluate vascular density in super­ficial and deep capillary plexuses of the retina, measured using optical coherence tomography angiography in patients with branch retinal vein occlusion. Affected eyes were compared with the contralateral eye of the same patient and both were comp...

Optical coherence tomography angiography findings in malignant hypertensive retinopathy

Arq. bras. oftalmol; 82 (1), 2019
ABSTRACT A 33-year-old male presented to our clinic with low vision in both eyes that started during the previous week. Visual acuity was 20/63 in the right eye and 20/50 in the left eye. Fundus examination revealed signs of hypertensive retinopathy; thus, a multidisciplinary approach was adopted for the...
