PURPOSE To evaluate myopia prevalence, myopia progression, and various potential myopia risk factors in third-year law students. DESIGN Cross-sectional study and survey. PARTICIPANTS One hundred seventy-nine third-year law students at the University of Pennsylvania. METHODS We administered a questionnaire to assess the prevalence of myopia, myopia progression, and risk factors, including ...

PURPOSE To compare the posterior corneal curvature changes, in terms of corneal power and asphercity, following Refractive Small Incision Lenticule Extraction (ReLEx SMILE) procedure for low, moderate, and high myopia. METHODS This retrospective, non randomized, comparative, interventional trial; included 52 eyes of 26 patients, divided in three groups: low myopia (myopia ≤3 D [diopters] sphe...

BACKGROUND Myopia is a leading cause of preventable blindness. Although, multiple cross-sectional epidemiological studies have confirmed that there is a high prevalence of myopia in high school-aged students in China. However, few longitudinal studies have been performed to assess junior high school students. In the present study, we investigate changes in the prevalence of myopia in third year...

PURPOSE To test the hypothesis that (1) there are quantitative differences in the cellular responses in the corneal stroma after photorefractive keratectomy (PRK) for low myopia compared to high myopia and (2) there are both qualitative and quantitative differences in the cellular responses in the corneal stroma after PRK for high myopia and laser in situ keratomileusis (LASIK) for high myopia....

purpose: to report the clinico-pathological and ultrastructural features of a case of meesmann corneal dystrophy (mcd). case report: a 10-year-old boy presented with decreased vision in both eyes since early childhood. slitlamp biomicroscopy disclosed diffuse intraepithelial microcystic changes in the cornea but other layers appeared unremarkable. high pathologic myopia and amblyopia were other...

Any treatment to prevent the onset of juvenile myopia will require predictive tests in order to determine which children should receive treatment. Three risk factors for myopia were evaluated for their ability to predict myopia: (a) refraction at school entry; (b) refraction in infancy; and (c) parental history of myopia. Bayes' theorem was used to estimate these conditional probabilities. Refr...

PURPOSE To estimate gender- and age-specific prevalence of myopia and identify risk indicators for myopia in a population-based sample of Latino adults aged 40 years and older in La Puente, California. METHODS Noncycloplegic automated refraction with supplemental standardized subjective refraction was performed for presenting visual acuity worse than 20/20. Potential risk indicators for myopi...

OBJECTIVE To identify the major risk factors for primary open-angle glaucoma (POAG) in individuals of African descent. METHODS We searched PubMed for relevant articles, with results spanning April 1947 to present. All abstracts were reviewed and, where relevant to POAG and race, articles were catalogued and analyzed. Additional sources were identified through citations in articles returned by...
