ABSTRACT Objective To evaluate the indirect ophthalmoscopy performed in ophthalmologic consultations, analyzing the prevalence of the study and comparing them with the reason for the consultation. Methods Cross-sectional study, with data found during the indirect ophthalmoscopy exam of inpatients or in emergency room care. The data analyzed for each patient was sex, the requested medical age, the reason for the consultation and the funduscopic examination findings. Results One hundred and four patients were evaluated and 43.27% of patients with a […]

ABSTRACT Objective Vascular findings in preeclampsia are usually attributed to increased vascular tone. Recently, however, important studies have improved the understanding of the main pathophysiological events in this condition, especially vascular brain remodeling, impaired autoregulation, and damage of the blood-brain barrier, which are well recognized features of cerebral overperfusion. Methods In this study, the association between choriocapillaris ischemia with ophthalmic artery blood flow parameters on orbital Doppler ultrasound is reported for the first time using multivariate logistic models. Multivariate logistic […]

ABSTRACT Silicone oil has been an important intraocular tamponade in retinopexy in cases of complicated retinal detachment surgery. The increase of intraocular pressure and development of secondary glaucoma are a known complication of its use. A variety of mechanisms have been proposed for the pathogenesis, depending on the onset. This article aims to review the literature about pathogenesis, the incidence and risk factors, as well as the treatment of this pathology.

ABSTRACT Purpose: To describe an innovative animal model of eye transplantation used in rabbits. Methods: six Dutch-belted male rabbits were submitted to lateral orbitotomy in the right eye, wide retrobulbar anatomy exposure, dissection of the structures, identification and distal section of the optic nerve followed by anastomosis either by vicryl (group 1) or fibrin glue (group 2). Electroretinography recording was performed before the section of the optic nerve and every 30 seconds after, to monitor the function of retina. Left […]

ABSTRACT Antiphospholipid antibody syndrome (APS) is characterized by the development of venous and/or arterial thrombosis and by gestational morbidity (recurrent fetal losses) in the presence of antiphospholipid antibodies. We report the case of a 38-year-old woman who was diagnosed with primary APS from thromboembolic abnormalities in the retinal periphery that led to retinal ischemia. The aim of this study is to share with physicians and medical undergraduates an atypical manifestation of the syndrome that is the most common acquired thrombophilia, […]

Abstract Acute zonal occult external retinopathy (AZOOR) was first described by Gass in 1993 as a syndrome with rapid loss of one or more large areas of the external retinal segments. Male, 35 years, with Crohn’s disease complaining of occasional eye pain and right eye nictalopia since childhood. In regular use of azathioprine and mesalazine. better visual acuity 20/20 OU. At fundoscopy, hyperpigmented lesions in the right temporal arcade of the right eye, in trellis, accompanying local vasculature. After exclusion […]

Abstract Objective: The objective of this work was to generate information about the profile of the patients submitted to Intravitreal Injections (IVIs) and also to evaluate the indications and costs of the procedure. Methods: The study was carried out with own protocols, applied through the analysis of medical records of patients submitted to IVIs at the State Public Servant Hospital of São Paulo from January 2017 to June 2018. Data were analyzed in the form of descriptive study. Results: The […]

Abstract Objective: Poor sleep quality have affect on neuronal structure in central nervous system. We aimed to investigate the effects of sleep quality on the thickness of retinal nerve fiber layer (RNFL), macula, and ganglion cell complex (GCC) obtained by optical coherence tomography (OCT) in healthy Caucasian adolescents. Methods: In this prospective cross-sectional study,100 healthy adolescents were evaluated for determining of sleep quality score by the Pittsburgh sleep quality index(PSQI) and were monitored for detection of sleep efficiency(%) by Sense […]
