ABSTRACT Objective: Early and accurate detection of corneal ectasias is essential for appropriate clinical management. The combined use of Pentacam and anterior segment OCT allows for a more comprehensive assessment of the morphological abnormalities associated with corneal ectasias, enabling earlier differentiation between normal and suspect cases. This study aims to investigate the relationship between OCT and Pentacam findings in the detection of corneal ectasias, analyzing their interdependence and clinical relevance. Methods: An analytical cross-sectional observational study based on data collected […]

ABSTRACT Objective: To characterize structural optic nerve changes in Ecuadorian glaucoma patients using optical coherence tomography data from 2015 to 2022. Methods: This retrospective study analyzed anonymized optical coherence tomography data from 301 eyes of 162 patients diagnosed with primary open-angle glaucoma. Data were acquired using the Nidek RS-330 and analyzed with Statistical Package for the Social Sciences, version 21. We assessed peripapillary retinal nerve fiber layer thickness (global, quadrants, and clock-hour sectors) and cup-to-disc ratios. Results: The mean global […]

ABSTRACT Objective: To analyze how inappropriate pharmacotherapy use influences glaucoma progression in patients from Paraíba’s hinterlands. Methods: A field-based, quantitative, cross-sectional study was conducted at the Frei Damião Specialty Center in Patos (PB), with 104 participants diagnosed with glaucoma. Patients unable to respond or who did not attend the appointments in the past 12 months were excluded. Data collection was conducted in person using three questionnaires: one on clinical and socioeconomic variables and two using the Morisky scale to assess […]

ABSTRACT Objective: To analyze the distribution of ophthalmologists across Brazilian regions to identify its association with hospital admission indicators for visual morbidities in 2021. Methods: This is an ecological study that used data from DATASUS and the Conselho Brasileiro de Oftalmologia. Rates of ophthalmologists and hospital admissions per 100,000 inhabitants were calculated. Results: A higher concentration of ophthalmologists was found in the Southeast and South regions, while the North and Northeast showed proportionally higher rates of hospital admissions. An inverse […]

ABSTRACT Objective: To assess the knowledge and practice of nurses regarding the Red Reflex Test (RRT). Methods: A cross-sectional study with a quantitative approach was conducted with professional nurses in São Luís, Maranhão, between October 15, 2023, and January 15, 2024. A questionnaire was applied, including sociodemographic variables and an assessment of knowledge and practice related to the RRT. Data were analyzed using descriptive statistics with STATA 14.0. Results: A total of 49 nurses working in healthcare assistance participated in […]

ABSTRACT This case series presents the shamrock sign, a novel aberrometry pattern characterized by trefoil and coma, as a potential diagnostic marker for nuclear cataracts associated with myopic shift. This study highlights its clinical relevance and contribution to early detection and management. The primary diagnosis was nuclear cataracts inducing myopic shift. All patients underwent phacoemulsification with intraocular lens implantation. Postoperatively, all cases showed marked reductions in higher-order aberrations, including spherical aberration and trefoil, with complete resolution of the shamrock sign. […]

ABSTRACT Objective: To evaluate the incidence of retinopathy of prematurity and of its outcomes in a reference maternity hospital in northeastern Brazil and to identify associated factors. Methods: A cross-sectional, retrospective study was conducted using secondary data from newborns screened between August 2020 and November 2022. Results: The statistical analysis included 166 infants. The disease incidence was 40% (66 cases). Stage 2 was the most incident (46 cases), followed by stage 1 (15 cases) and stage 3 (5 cases). No […]

ABSTRACT We report a rare case of spontaneous extrusion of a Müller sphere implant three decades after ocular evisceration. A 44-year-old woman, with a history of evisceration of the left eye due to phthisis bulbi from congenital syphilis, presented with extrusion of an orbital implant. Surgical management consisted of reimplantation of a new sphere using a reconstructive technique with scleral shell and biological support. Postoperative recovery was favorable, and progressive prosthetic rehabilitation provided satisfactory functional and cosmetic outcomes. This case […]
