Abstract

Purpose: To assess whether the type of corneal topographic pattern is stable during a 1-minute pause in blinking in healthy subjects. Setting: First Department of Ophthalmology, Semmelweis University, Budapest, Hungary. Methods: Corneal topographic images were recorded 5, 15, 30, and 60 seconds after a complete blink in the right eyes of 36 healthy subjects using the TMS-1 instrument in a prospective observational study. The topographic pattern of each image was assessed from the color-coded topographic map and classified into 5 groups (in order of decreasing regularity: round, oval, symmetric bow-tie, asymmetric bow-tie, and irregular). Results: During the 60-second period, a change in the type of topographic pattern was found in 19 subjects (53%), whereas in 17 subjects (47%) the pattern was stable. The alteration of the topographic pattern was statistically significant (P
