The outcomes were prevalence […]

Objective: Evaluate ocular trauma cases related to falling in elderly patients e compare the prevalence and severity of the cases. Methods: A series of cases was made with 52 patients aging 60 or more within the period of 36 months presenting ocular trauma related to falling, whereas the prevalence between the gender, the need for hospitalization or surgery and subsequent visual deficit were evaluated, as well as the severity of the cases. Results: Thirty-three (63.5%) of 52 patients were from […]

Objective: Some studies have hypothesized that an unfavourable higher order aberrometric profile could act as an amblyogenic mechanism and may be responsible for some amblyopic cases that are refractory to conventional treatment or cases of “idiopathic” amblyopia. This study compared the aberrometric profile in amblyopic children to that of children with normal visual development and compared the aberrometric profile in corrected amblyopic eyes and refractory amblyopic eyes with that of healthy eyes. Methods: Cross-sectional study with three groups of children […]

PURPOSE: To evaluate the sensitivity of the photoscreener equipment to detect ocular changes in informative children comparing with the data obtained by the E Snellen´s table. METHODS: We evaluated 500 children between 5 and 12 years old, from a school of Botucatu city, São Paulo state. The children were submitted to a visual acuity test using the Snellen´s E Table and were photographed with the photoscreenerTM system model MTI-PS100, following the photos’ analyze. RESULTS: There were negative agreement (children with […]

PURPOSE: The goal of this research is to relate the results of congenital lacrimonasal duct obstruction treatment and epidemic aspects in children.
