Correlation between intereye difference in visual field mean deviation values and relative afferent pupillary response as measured by an automated pupillometer in subjects with glaucoma.

Purpose: To evaluate the effectiveness of a new binocular infrared computerized pupillometer in the quantitative measurement of the relative afferent pupillary response in patients with glaucoma by assessing the correlation of the intereye difference in visual function as measured by standard automated perimetry (SAP) with the intereye difference in the afferent pupillary response.

Methods: Twenty-three patients with glaucoma underwent examination with a prototype, automated, binocular pupillometer. Correlation between the intereye difference in the afferent pupillary response and the intereye difference in mean deviation (MD) was explored.

Corneal ectasia after myopic laser in situ keratomileusis: a long-term study.

Background: The purpose of this study was to evaluate the long-term postoperative incidence of and key factors in the genesis of corneal ectasia after myopic laser-assisted in situ keratomileusis (LASIK) in a large number of cases.

Methods: A retrospective review of one surgeon's myopic LASIK database was performed. Patients were stratified into two groups based on date of surgery, ie, group 1 (1313 eyes) from 1999 to 2001 and group 2 (2714 eyes) from 2001 to 2003.
