PURPOSE To assess possible refractive changes according to age and strabismus in a statistically significant cohort. METHODS A population-based sample of 12,534 subjects 0.5 to 20 years old, examined between 2004 and 2006, was tested. Each subject received a complete orthoptic examination, including spherocylindrical streak retinoscopy in cycloplegia. Patients were divided into those with ort...

AIM To evaluate histomorphometrically the optic nerve head in highly myopic eyes with absolute secondary angle closure glaucoma. METHODS Optic disc sections of 16 highly myopic eyes with an axial length of more than 26 mm and of 19 eyes with an axial length of less than 26 mm were histomorphometrically evaluated. All eyes had been enucleated due to painful absolute secondary angle closure gla...

We have carried out a number of different studies in chicks to examine the relationship between choroidal blood flow and myopic eye growth, and between accommodation and myopic eye growth. Our studies on choroidal blood flow show that myopic eye growth produced by form vision degradation leads to dramatic reductions in choroidal blood flow. These reductions appear directly attributable to the e...

PURPOSE To investigate changes of the axial length in normal eyes and highly myopic eyes and influence of myopic macular complications in Japanese adults. STUDY DESIGN Retrospective longitudinal case series. METHODS The changes in the axial length of 316 eyes from 316 patients (mean age, 63.8 ± 9.0 years; range, 34-82; 240 females) examined using IOLMaster with a follow-up period of at leas...

OBJECTIVE Dogs, like humans, experience eye changes with aging: hardening and clouding of the lens and accumulated oxidative damage from UV sunlight. It has been debated whether such changes could be affecting the visual function of dogs. The objective of this study was to determine if autorefractometry could be used to measure visual function in dogs. ANIMALS AND METHODS Nine Beagle dogs (ag...

purpose: to determine the effect of horizontal recti surgery on visual acuity and head posture and electronystagmographic indices in patients with congenital nystagmus. methods: this prospective comparative case series was conducted on 58 patients with congenital nystagmus who were referred to our clinic over three years. patients were divided into three groups: the first group (29 cases) had h...
