Interest in peripheral refractive errors has increased as it was hypothesized that peripheral hypermetropia might provide a stimulus for axial elongation (Smith et al., 2005), this study was to determine relative peripheral refractive errors (RPRE) of the eyes of a group of Chinese children and adults. Central and peripheral (20 degrees , 30 degrees , 40 degrees at nasal, temporal, superior and...

The baseline examination included non-cycloplegic auto-refractometry and questionnaire interview. Measurements were repeated at the follow-up. RESULTS Among 50...
Here, we report on a patient with pseudoexfoliation syndrome who developed acute angle-closure glaucoma with a marked myopic shift due to anterior dislocation of the posterior chamber intraocular lens almost 16 months after an uneventful phacoemulsification. Examination with a Scheimpflug camera was extremely useful in confirming the diagnosis. This is the fist case of late-onset angle-closure ...
