Seasonal variation of intraocular pressure in normal and glaucomatous eyes
Koga T; Tanihara HJapanese Journal of Clinical Ophthalmology 2001; 55: 1519-1522
A review of literature has shown that intraocular pressure (IOP) tends to be higher during the winter in normal and glaucomatous eyes. This tendency is more manifest in the latter. Greater seasonal fluctuation in IOP is one of the risk factors of glaucoma as it is associated with more frequent deterioration of the visual field. Various theories are presented to account for the higher IOP level in winter, including: elevated catecholamines in the serum, increased aqueous secretion secondary to elevated blood pressure, and decrease in aqueous outflow. Seasonal variation in IOP should be taken into account in the long-term management of glaucoma patients. LA: Japanese
