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 […]

ABSTRACT Objective: to offer basic ophthalmological knowledge to the local community through a scientific exhibition and evaluate the impact on visitors’ learning. Methods: to hold an interactive exhibition on the human eye and ocular health at the Central Library (BCE) of the State University of Maringá (UEM-PR) in June and July 2024, open to the population. A 10-question questionnaire was administered before and after the students’ interaction with visitors at the exhibition. Results: 2,348 valid questionnaires were administered (1,174 initially […]

ABSTRACT Objective: To determine the prevalence of blindness in elderly people from quilombola communities located in the immediate geographic region of Araguaína, in the north of Tocantins. Methods: A cross-sectional study was carried out, in which 80 residents, aged 60 or over, from 4 certified quilombola communities in this region were examined: Pé do Morro, Baviera, Dona Juscelina, and Cocalinho. Everyone answered a questionnaire on demographic and socioeconomic variables, and underwent a visual acuity exam, using the Snellen Table. For […]

ABSTRACT Objective: To evaluate refractive and topographic outcomes before and at least 7 years after intrastromal ring segment implantation surgery in patients with keratoconus. Methods: Long-term retrospective longitudinal study carried out with 35 patients (62 eyes) aged 10 to 30 who underwent intrastromal ring segment implantation using a manual technique. Different arc rings were analyzed across various keratoconus types. Results: Significant improvements in topographic astigmatism (p = 0.001) and corrected distance visual acuity (p < 0.001) were observed, with no [...]
