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 […]

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 […]

OBJECTIVE: To describe a novel technique for clinical characterization of corneal biomechanics using non-invasive dynamic imaging. METHODS: Corneal deformation response during non contact tonometry (NCT) is monitored by ultra-high-speed (UHS) photography. The Oculus Corvis ST (Scheimpflug Technology; Wetzlar, Germany) has a UHS Scheimpflug camera, taking over 4,300 frames per second and of a single 8mm horizontal slit, for monitoring corneal deformation response to NCT. The metered collimated air pulse or puff has a symmetrical configuration and fixed maximal internal pump […]
