ABSTRACT Objective: To study vertex-optical distance variation and estimate its impact on manifest refraction. Methods: Prospective study in a private clinic using the Vision-S™ 700 with five forehead positions. Forehead on the third position showed the closest vertex-optical distance of 12mm. Results: Analysis of 52 eyes from 26 patients revealed mean differences in vertex-optical distance of 12.25mm (right eye) and 11.75mm (left eye). A 2mm change in vertex-optical distance resulted in a 0.05D change for a 5D spherical equivalent and […]

ABSTRACT Objective: To evaluate the epidemiological, clinical, and imaging profile of lesions that mimic choroidal melanoma. Methods: Retrospective study of medical records of suspected choroidal melanoma lesions referred to the Ocular Oncology Service from the Universidade Federal de São Paulo, from 2014 to 2020. Demographic data, clinical history, and exams were evaluated. Results: A total of 104 patients (mean age: 65.57 ± 13.18; 49.04% female) were referred to our service with suspected choroidal melanoma. Of these, 32 (30.77%) were classified […]

ABSTRACT Objective: To determine the prevalence of ocular alterations in patients diagnosed with dengue, admitted to a reference center for infectious and parasitic diseases in Manaus (AM), Brazil. Methods: This was an observational, analytical, and prospective case series study with 33 patients admitted to the hospital with positive clinical pathology tests during a 90-day period of a dengue epidemic in 2011. The investigations included measurement of visual acuity, macular assessment with Amsler grid test, fundus biomicroscopy, retinography and optical coherence […]

ABSTRACT Objective: To assess the clinical-epidemiological profile of patients with eyelid trauma associated with lacrimal canaliculus laceration, factors related to trauma and surgical intervention, and to evaluate post-surgical anatomical and functional success. Methods: A retrospective and longitudinal analytical study was conducted, in which chart analysis was performed for patients with eyelid trauma and associated canalicular injury, who were operated on from January 1, 2015, to July 31, 2022. Patients were selected and contacted for in-person evaluation and tests to analyze […]

ABSTRACT Objective: To compare the hypotensive effect of SLT vs the use of latanoprost in the initial management of patients with suspected glaucoma and diagnosis of glaucoma. To evaluate the patients’ quality of life using the Glaucoma Quality of Life questionnaire. Methods: Randomized controlled clinical trial conducted in the city of Cartagena, Colombia, between October 2021 to June 2023. Assignment to the SLT or latanoprost group with follow-up at days 7, 30, 90, 180, and 365 in patients diagnosed with […]

ABSTRACT Objective To evaluate the preliminary medium-term results (up to 6 months) of the stand-alone use of XEN® Gel Stent implantation or in combination with cataract surgery in the Brazilian population. Methods A retrospective longitudinal study was carried out on eyes with primary open-angle glaucoma consecutively submitted to XEN® Gel Stent implantation surgery alone (XEN® Group) or in combination with cataract surgery (Phaco-XEN® Group) in the same center between April and December 2023. The ability to reduce intraocular pressure and […]

ABSTRACT Objective: To assess myopia prevalence in children from public schools of the metropolitan region of Porto Alegre, in Rio Grande do Sul. Methods: It is a prospective cross-sectional study with a sample of 330 children from public schools of the metropolitan region of Porto Alegre, from 5 to 20 years old. The students were submitted to an ophthalmological evaluation including auto-refractor measurements, best corrected and uncorrected visual acuity, subjective refraction under cycloplegia and axial length. The outcomes were prevalence […]

ABSTRACT Objective: To assess the performance of a portable autorefractor as refractor and screening tool for refractive errors in schoolchildren. Methods: Cross-sectional observational study. Refractometric measurements of children between 5 and 10 years old were obtained through four methods: 2WIN under non-cycloplegic conditions, and 2WIN, conventional autorefractor, and retinoscopy, under cycloplegic conditions. Correlations and agreement between the methods and accuracy of the portable autorefractor to define whether to prescribe glasses were assessed. Results: The mean age ± standard deviation was […]
