ABSTRACT Objective: To assess the diagnostic accuracy of a deep learning tool for cataract detection using retinal images from the Ocular Disease Intelligent Recognition (ODIR) public dataset. Methods: The study was conducted using a publicly available dataset, with a web-based Artificial Intelligence tool. This was an observational, cross-sectional study. A total of 230 fundus images were selected from the ODIR dataset, equally divided between 115 cataract cases and 115 non-cataract cases. The images were processed using the Gobvision Artificial Intelligence […]

ABSTRACT Objective: To evaluate the sociodemographic and ophthalmological characteristics of patients with Ahmed Valve implantation, as well as the postoperative evolution. Methods: Cross-sectional observational study, in which 85 patients were selected to compose the sample, data were collected through electronic medical records. Results: The average age was 57.3 years. There was a higher prevalence of males at 65.9%. The majority of patients were from other regions of the state, had incomplete primary education and had systemic diseases. The most common […]

ABSTRACT Objective: To evaluate parents’ knowledge and perceptions about amblyopia and its treatment after their child’s diagnosis. Methods: A cross-sectional study included parents of 30 children diagnosed with amblyopia, recruited from a pediatric ophthalmology clinic. Participants completed a questionnaire after the diagnosis of their children, before receiving amblyopia education. The questionnaire assessed parental knowledge, socioeconomic background, and barriers to care. Statistical analyses included descriptive statistics and logistic regression to identify factors associated with awareness and adhesion. Results: Most parents (85.7%) […]

ABSTRACT Objective: To evaluate the agreement of biometric parameters measured by the ANTERION and IOLMaster700 devices in a Brazilian population, considering statistical differences and their clinical relevance. Methods: A retrospective comparative study included cataract patients who underwent biometric examination with ANTERION and IOLMaster700 between September and December 2023. The parameters evaluated were anterior keratometry, axial length, central corneal thickness, anterior chamber depth, white-to-white diameter, and lens thickness. Agreement and correlation were assessed using Bland-Altman and scatter plots. Results: A total […]

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 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 sporadic and congenital neurocutaneous disease characterized primarily by the presence of cutaneous and extracutaneous capillary malformations. Our understanding of this syndrome has improved since its first description over the years, particularly with the identification of different clinical presentations and new genetic mutations. Ocular manifestations are frequently observed in this syndrome but often develop insidiously and can threaten visual prognosis. Thus, an appreciation of different ophthalmological manifestations seems crucial. In the same perspective, we report […]

ABSTRACT Objective: Embryonic exposure to valproic acid is a widely used model for the study of neurodevelopmental disorders such as autism spectrum disorders. In zebrafish, early exposure to valproic acid results in the major behavioral, neurological, and genetic phenotypes of this disorder. Autism spectrum disorders have several associated symptoms, such as changes in sensory processing, sleep problems, and hyper- or hyposensitivity to light. This work investigates the hypothesis of changes at the retinal level due to embryonic exposure to valproic […]
