Corneal thickness changes following sleep and overnight contact lens wear in the primate (Macaca fascicularis)

Abstract

Corneal thickness was monitored on seven cynomolgus monkeys (Macaca fascicularis) over a 76 hour period. During this time, corneal thickness measurements were also made on six monkeys after overnight wear of a hydrogel contact lens in one eye. Mean corneal thickness was 417 +/- 12 microns. An overall diurnal variation of 16 +/- 5 microns (3.8 +/- 1.2%) was found. During the first half hour after waking, corneal thickness changes ranged from -9 microns to +14 microns. After overnight contact lens wear, the cornea had swelled an average of 42 +/- 24 microns (9.1 +/- 4.8%). Following lens removal, the cornea returned to normal thickness within approximately 90 minutes. These results are similar to those found in humans and indicate that with respect to contact lens induced corneal thickness changes, the cynomolgus monkey is a suitable model for the physiological response to contact lens wear.

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
