ABSTRACT Objective To identify eye conditions associated to social distancing and related increase in screen time exposure on children and teenagers. Methods Observational, descriptive and analytical study, with a cross-section design, carried out between July and August 2021, by questionnaire survey. Results Headaches related to excessive screen time exposure were reported by 26.51% of the students surveyed, while 38.8% reported suspect convergence insufficiency. Regarding the questionnaire about dry eye, 18.8% were symptomatic and 7.5% reported hard-to-manage symptoms. Computers were the […]

ABSTRACT Objective To develop and validate a course on basic sciences in Ophthalmology. Methods A methodological study for the development and validation of a teaching and instructional material, an online course through the ADDIE instructional design, was prepared at the Faculdade Pernambucana de Saúde (FPS). The design consists of three steps out of five: Analysis, Design, and Development. Bloom’s revised Taxonomy was used to define the learning objectives. The course was submitted remotely to content validation, through a consensus group […]

ABSTRACT Objective To identify the epidemiological profile and visual benefit of the patient using the Unified Health System after cataract surgery. Methods This is a descriptive, cross-sectional and retrospective study with the analysis of medical records, between October and November 2020. We included 573 eyes of 319 patients that were selected for cataract surgery. Gender, age, cataract classification, pre-and post-surgery corrected acuity, smoking, presence of comorbidities, and previous ocular alterations were analyzed. Results Of the cataract surgeries performed, the mean […]

ABSTRACT Objective To analyze the short, medium and long-term efficacy and stability in 46 eyes with keratoconus, operated with Ferrara intrastromal corneal ring segments. Methods The primary endpoint was the mean keratometry of total corneal refractive power. We also studied the effects of age, degree of keratoconus and clinical phenotype on the results, as well as the following keratometry variations and aberrometry variations: flattest, most curved, mean, maximum, astigmatism, root mean square of primary coma aberration and root mean square […]

ABSTRACT Purpose: To retrospectively analyze the changes in corneal keratometry and astigmatism after intrastromal ring surgery, comparing the use of one long arch segment versus two traditional arc length segments. Methods: A cross-sectional study obtained data from 94 eyes of patients diagnosed with keratoconus that underwent surgical treatment with corneal ring implant. They were divided into two groups according to the type of implant received: one long-arch segment (Group A) or two traditional segments (Group B), both 250 microns thick. […]

ABSTRACT Objective: To evaluate if participants, subjected to whole-body vibration, two different types of media (paper versus tablet) and two lighting environments (fluorescent versus LED), present a difference in eye-movement parameters during reading tasks. Methods: Fourteen adults silently read two different texts in each one of the eight randomized testing conditions (whole-body vibration versus media versus lighting), resulting in 16 different texts read per individual. Whole-body vibration was applied in the vertical direction, 5Hz and 0.8 m/s2 root-mean-square amplitude, a […]

ABSTRACT Purpose: This study aimed to implement a health-related quality of life (HRQoL) assessment protocol to measure the consequences of a rehabilitation program for visual impaired people at a leading reference institute in Brazil. Methods: A cross-sectional study was conducted with 60 visual impaired adults enrolled in a Rehabilitation Program of the Instituto Benjamin Constant. The research protocol consisted of a questionnaire with personal data, social, demographic, and clinical information; the EQ-5D-3L instrument for generic HRQoL measurement; the Patient Health […]

ABSTRACT Objective: To evaluate the economic impact of starting the treatment of primary open angle glaucoma with non-pharmacological strategies within the scope of reference centers for the treatment of glaucoma in the Unified Health System. Methods: The population of this study comes from a hypothetical cohort of patients aged 60 years with initial primary open angle glaucoma. The reference strategy (strategy 1) is based only on the use of eye drops, following the guidelines of the clinical protocol of the […]
