OBJECTIVE: to study the state of anterior eye segment (AES) hemomicrocirculation by means of application fluorescein angiography (FAG) in patients with cataract of different maturity solely or in combination with pseudoexfoliation syndrome (PES).
MATERIAL AND METHODS: A total of 58 patients (98 eyes) with cataract or cataract and PES aged from 45 to 82 years (68.4 +/- 5.2 years on average) were assessed (study group). These patients were divided into 2 subgroups: I--patients with cataract and no PES, II--patients with both cataract and PES. The control group included 15 individuals (21 eyes) without ophthalmic pathology aged from 47 to 72 years (57.7 +/- 4.7 years on average). Conjunctival microcirculation was assessed by the proposed FAG method, in which the dye is introduced directly to the bulbar conjunctival capillary bed through application.
RESULTS: The following parameters of application FAG that characterize hemomicrocirculation of the AES were analyzed: venular appearance time, venous phase duration, beginning of extravasal hyperfluorescence, microvessels functionality regarding their number and caliber. All patients demonstrated hypoperfusion, the intensity of which correlated with cataract maturation and the presence of PES.
CONCLUSION: Application FAG adequately reflects the state of hemomicrocirculation of the AES in cataracts and PES.
