Abstract

This paper presents a comparison of spectroscopic properties of aqueous humour in patients with cataract (60 patients, 60 eyes) and combination of cataract and primary open angle glaucoma (POAG, 36 patients, 36 eyes). The samples of aqueous humour were collected during the surgery. Both groups of patients were treated with different types of local drug antihypertensive therapy with different multiplicity and duration of instillation during the preoperative period. The absorption spectrum of aqueous humour were measured in the wavelength range 190- 1100 nm. There were two absorption bands with maximums at 202 and 267 nm in the absorption spectrum (2nd maximum of some samples was shifted to larger wavelengths). The mean absorbance of aqueous humour at 202 nm in patients without POAG was significantly lower than in patients with POAG. This difference could be explained with accumulation of metabolites in aqueous humour of patients with POAG, which in turn may be caused by deceleration of aqueous humour flow in patients with POAG. Meanwhile, there were no statistically significant differences of mean absorbance of aqueous humour at 267 nm between the patients of both groups.

Keywords: cataract; primary open-angle glaucoma; optical density of aqueous humour; spectroscopy.
