ABSTRACT Objective: To evaluate the prevalence and severity of dry eye disease in patients with a history of COVID-19 infection. Methods: A total of 76 patients who had recovered from COVID-19 were included in the study. Dry eye disease was assessed using subjective and objective measures, including the Ocular Surface Disease Index questionnaire, tear break-up time, Schirmer test, and corneal staining. Results: This study included 76 patients with a mean age of 54.55 ± 10.61 years. The results revealed a […]

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 know the prevalence of visual impairment in children from pre-selected public schools, as well as to analyze and intervene in it. Methods: The study was conducted in four stages. During the first and second ones, school professionals and medical students were trained in visual screening to perform the visual acuity of children in the first years of Elementary School. Children with altered acuity received ophthalmologic referral for diagnosis and intervention. Results: Of the 450 children screened, 64 […]

ABSTRACT Introduction: Myopia is a growing global concern and there is a lack of studies on its prevalence among Brazilian schoolchildren. Methods: This study aimed to determine the prevalence of myopia in Brazilian children aged 3–18 years through a review and meta-analysis of published studies. Eleven high-quality studies were analyzed following the 2022 PRISMA guidelines. Prevalence was calculated using a meta-analysis, considering the heterogeneity among the studies. Results: The overall crude prevalence of myopia in Brazilian children was 7.65%. There […]

ABSTRACT Objective: This systematic review aimed to investigate the prevalence and incidence of optic neuropathy in older adults.

The outcomes were prevalence […]

ABSTRACT One in four patients affected by maxillofacial trauma will have concomitant orbital fractures and ocular injuries; therefore, an ophthalmological evaluation is recommended for all patients who have been affected by facial trauma. Some ophthalmological exams soon after the trauma can be decisive for the preservation of visual acuity. Patients with physical examination findings of poor visual acuity, afferent pupillary defect, radiographic images with high depth of orbital fracture, are at greater risk of vision loss and specific concern for […]

Purpose: To determine the prevalence of predisposing factors of low visual acuity among the students of the Geraldo Reis University College in Niterói-RJ. Methods: This was a cross-sectional observational study during which the visual acuity of the volunteer students who adhered to the assent term was measured. Those students whose visual acuity did not exceed 0.8 in at least one eye or who presented a difference between the eyes of two lines or more in the Snellen table were selected […]
