Accommodation: its relation to refractive errors, amblyopia and biometric parameters.
AIM To study accommodation in relation to different refractive errors, amblyopia and to measure the anatomical changes in the accommodating eye MATERIALS AND METHODS We studied the amplitude of accommodation (AA) in 150 patients in the age group 11 ± 30 years which included emmetropes, myopes, hypermetropes and hypermetropic amblyopes using the Royal Air Force (RAF) rule. The anterior chamber...

15 صفحه اولPrevalence of Amblyopia and Refractive Errors Among Primary School Children.
PURPOSE To determine the prevalence of amblyopia and refractive errors among 7 to 12-year-old primary school children in Tehran, Iran. METHODS This population-based cross-sectional study included 2,410 randomly selected students. Visual acuity was tested using an E-chart on Yang vision tester.

متن کاملAnisometropia--its relation to amblyopia and eccentric fixation.
IN the refraction clinic the visual improvement cannot always be correlated with the degree of anisometropia. The literature shows that anisometropic amblyopia is a well-recognized condition, but opinions differ regarding the relationship between anisometropia and amblyopia. As the published studies do not consider the factor of eccentric fixation as a possible variable, we have investigated it...
متن کاملRefractive Status at Birth: Its Relation to Newborn Physical Parameters at Birth and Gestational Age
BACKGROUND Refractive status at birth is related to gestational age. Preterm babies have myopia which decreases as gestational age increases and term babies are known to be hypermetropic. This study looked at the correlation of refractive status with birth weight in term and preterm babies, and with physical indicators of intra-uterine growth such as the head circumference and length of the bab...
