ABSTRACT Objective: To evaluate the tomography accuracy of Cirrus 5000 optical controls in patients with or without keratoconus for pachymetry measurements by image scanning patterns. Methods: A prospective, cross-sectional and mixed study was performed in 20 eyes, where 37 parameters of each sample was analyzed and repeated 5 times. Results: Only four samples (vertex full, maximum epithelial pachymetry at 5 to 7.0mm, maximum epithelial pachymetry at 7 to 9.0mm and epithelial pachymetry difference between minimum and average) samples showed a […]

ABSTRACT Choroidal metastasis is the most common intraocular malignancy. However, bilateral involvement remains exceptionally rare. We describe a case of a 57-year-old patient with no comorbidity who presented with progressive decrease in visual acuity of both eyes for 5 months duration. Fundus examination of both eyes revealed choroidal masses in the posterior pole with serous retinal detachment. She did not exhibit any respiratory symptoms, and systemic examinations were normal. Systemic investigation including computed tomography thorax revealed patient had lung tumour […]

ABSTRACT Background: There is a debate regarding the differences in intraocular pressure values between different types of dispersive ophthalmic viscosurgical devices in patients after phacoemulsification for cataracts. Objectives: We aim to evaluate the differences between hydroxypropyl methylcellulose and sodium hyaluronate alone or combined with chondroitin sulfate as ophthalmic viscosurgical devices after phacoemulsification in selected patients related to intraocular pressure. Methods: We conducted a systematic review and meta-analysis of randomized clinical trial data comparing only dispersive hydroxypropyl methylcellulose with sodium hyaluronate […]

ABSTRACT Objective: To assess the diagnostic accuracy of ChatGPT in analyzing OCT images. Methods: A total of 300 OCT images, previously interpreted by specialists, were analyzed by ChatGPT under three scenarios: image-only input; input with additional epidemiological data; and input with detailed clinical data. Sensitivity, specificity, and accuracy rates were compared across scenarios using appropriate statistical analyses (p < 0.05). Results: Overall accuracy was 66.33% in the image-only scenario, 82.33% with epidemiological data, and 92.67% with clinical data. Sensitivity for [...]

ABSTRACT Sturge-Weber Syndrome is a rare, non-hereditary developmental condition characterized by hamartomatous vascular proliferations affecting the brain and facial tissues. Its main features include corticocerebral angiomatosis, cerebral calcifications, epilepsy, ocular abnormalities, mental impairment, and a facial port-wine stain. This report aims to highlight the main features of Sturge-Weber Syndrome in a patient with unilateral facial and scalp nevus, ipsilateral glaucoma, and imaging alterations. A case study was conducted on a patient treated at an ophthalmology clinic. The diagnosis and follow-up […]

ABSTRACT Objective: To evaluate the cost-utility of latanoprostene bunod 0.024% as first-line therapy compared to the strategy recommended by the Clinical Protocol and Therapeutic Guidelines for primary open-angle glaucoma of the Brazilian Unified Health System. Methods: A cost-utility analysis was conducted using a hypothetical cohort and a Markov model. In the base-case scenario, the treatment strategy recommended by the Clinical Protocol and Therapeutic Guidelines was adopted, initiating therapy with timolol 0.5%. If the target intraocular pressure was not achieved, dorzolamide […]

ABSTRACT An 81-year-old male patient with systemic hypertension, diabetes mellitus, and dyslipidemia presented with sudden visual acuity loss in the right eye (RE) due to a branch retinal artery occlusion (BRAO) associated with macular edema. Despite treatment with intravitreal bevacizumab, the patient developed persistent inner retinal ischemia, evidenced by optical coherence tomography (OCT) findings of retinal inner plexiform layer (RIPL) alterations. Years later, he suffered an ischemic stroke, highlighting the association between retinal ischemic changes and systemic vascular risk. This […]

A produção de artigos científicos no Brasil é um percurso árduo, repleto de obstáculos. Na Oftalmologia, especialidade marcada por avanços constantes e pela necessidade de inovação, esses entraves tornam-se ainda mais evidentes. Vivemos em um país com enorme volume de pacientes, diversidade epidemiológica única e médicos talentosos. Contudo, transformar essa realidade clínica em ciência publicada exige superar muitas pedras no caminho. Diferentemente de países com carreiras acadêmicas estruturadas, no Brasil a pesquisa é quase sempre feita à margem da rotina […]
