ABSTRACT The objective was to investigate the efficacy of topical losartan in treating corneal scars in patients with varying clinical backgrounds. A case series with six patients diagnosed with corneal scars resulting from herpetic keratitis or complicated photorefractive keratectomy were treated with topical losartan at a concentration of 0.8 mg/mL. Each patient underwent comprehensive ophthalmologic evaluations, including anterior segment optical coherence tomography and corneal tomography, to assess clinical outcomes after treatment. Improvement in visual acuity was noted in five out […]

ABSTRACT Objective: To compare the efficacy and safety of the iStent inject® and iStent inject® W in patients with primary open-angle glaucoma (POAG) undergoing standalone or combined implantation with phacoemulsification. Methods: Retrospective longitudinal study including 103 eyes with mild-to-moderate POAG. Intraocular pressure (IOP), number of medications, absolute and relative success rates, survival analysis, and safety outcomes were evaluated over 12 months. Results: Fifty-nine eyes received iStent inject® (Group 1) and 44 received iStent inject® W (Group 2). Mean IOP decreased […]

ABSTRACT Objective: To develop and validate a prototype of magnifying glasses to improve precision and safety in the extraction of corneal foreign bodies. Methods: The prototype was made on a 3D printer using ABS material, containing a 30x magnifying glass and LED lighting. Validation was carried out by 22 specialist ophthalmologists using the Delphi method, who evaluated the device’s functionality, usability, aesthetics, safety, and durability. Statistical analysis included the Content Validity Index (CVI) and McDonald’s Omega coefficient. Results: The experts […]

ABSTRACT Objective: To determine the evolution of retinopathy of prematurity in patients treated with intravitreal antiangiogenics in the retina private practice. Methods: A retrospective descriptive observational case series study was conducted. The study was non-experimental and non-probabilistic. Based on a population of 61 newborns, with a 99% confidence interval and a margin of error of 1%, the sample would be 61 newborns. The data from Google Sheets was transferred to CVS and then the Statistical Package for the Package Power […]

ABSTRACT Objective: To underscore the critical importance of assessing the peripheral retina in all patients, especially those planning to use miotics. Methods: A retrospective and observational study was conducted at a single ophthalmological medical center, using records from the International Classification of Diseases (ICD-10) for closed-angle glaucoma and lesions predisposing to detachment. Participants in this study underwent anterior chamber assessment using the Goldman 3-Mirror lens and the Volk G-4 Gonioscopy lens. Peripheral retinal evaluation was conducted with indirect binocular ophthalmoscopy […]

ABSTRACT Objective: To identify corneal epithelial thickness profiles for early keratoconus diagnosis with the aid of Artificial Intelligence. Methods: A total of 496 eyes (306 normal and 190 with keratoconus) were analyzed using optical coherence tomography images. Results: Epithelial segmentation revealed distinct patterns between groups, highlighting early changes in epithelial thickness in keratoconus eyes. The findings reinforce the potential of artificial intelligence in disease screening, enabling a more precise and objective diagnostic approach. Conclusion: Implementing algorithms such as k-means can […]

ABSTRACT Objective: To outline the clinical and epidemiological profile of patients attended at the ophthalmology outpatient clinic of a university hospital, with emphasis on the presence of diabetes mellitus, diabetic retinopathy, and the type of ophthalmological follow-up. Methods: This was a cross-sectional, observational, and retrospective study in which electronic medical records of patients attended at the Ophthalmology Outpatient Clinic were analyzed during the period from March to August 2023 and compared with the same period in 2024. Medical records with […]

ABSTRACT Objective: To investigate the epidemiological profile of ocular toxoplasmosis in an ophthalmology hospital in western Paraná. Methods: A retrospective study conducted between 2015 and 2022 through the review of medical records, using the presence of chorioretinal scars as a presumptive diagnosis of ocular toxoplasmosis. Results: 3.03% of patients seen during the study period presented with presumptive ocular toxoplasmosis lesions, with a higher prevalence in women (57.25%) and in the age group of 60–79 years old (42.18%). Diabetes was observed […]
