Local ocular compensation for imposed local refractive error.
Chicks were raised in a low-ceiling environment to find out if their eye growth could compensate for locally imposed hyperopic refractive errors. These chicks became selectively more myopic in the upper visual field than chicks raised in a high-ceiling environment. The vitreous chamber in the low-ceiling birds showed a selective elongation in the ventral region that was not seen in the eyes of ...
متن کاملLocal Changes in Eye Growth induced by Imposed Local Refractive Error despite Active Accommodation
We have tested whether defocus imposed on local retinal areas can produce local changes in eye growth, even if accommodation is available to clear part of the imposed defocus. Hemi-field lenses were attached to little leather hoods that were worn by young chickens from day 11-15 post-hatching. The lens segments defocused either the nasal or the temporal visual field, or covered the full field. ...
متن کاملSupport for polygenic influences on ocular refractive error.
PURPOSE Refractive errors, myopia, and hyperopia are common conditions requiring corrective lenses. The familial clustering of myopia has been well established. Several chromosomal regions have been linked to high myopia (12q, 17q, and 18q), to quantitative refraction among twins (3q, 4q, 8p, and 11p), and to families with moderate myopia (22q). This study examined the familial aggregation and ...
متن کاملLocal ocular immunotherapy for experimental allergic conjunctivitis.
PURPOSE We studied the efficacy of eyedrops as local ocular immunotherapy against experimental allergic conjunctivitis. METHODS Guinea pigs were sensitized with an intraperitoneal injection of ovalbumin (OA). Three weeks after the sensitization, a low concentration (10 microg/mL) of OA eyedrops was administered once a day for 3 weeks. Six weeks after the sensitization, an allergic inflammatio...
متن کاملAssociation between Ocular Sensory Dominance and Refractive Error Asymmetry
PURPOSE To investigate the association between ocular sensory dominance and interocular refractive error difference (IRED). METHODS A total of 219 subjects were recruited. The refractive errors were determined by objective refraction with a fixation target located 6 meters away. 176 subjects were myopic, with 83 being anisometropic (IRED ≥ 0.75 D). 43 subjects were hyperopic, with 22 being an...
