| Summary: |
Purpose: The purpose of
this study was to evaluate retinal capillary blood flow
in patients with exudative AMD.
Material and methods: Twenty patients with exudative AMD
and twenty four patients age-matched control subjects,
were included into the study. Retinal capillary blood
flow was evaluated with Heidelberg Retinal Flowmeter (HRF),
measurements were taken in two macular regions. The
total mean flow and mean velocity were calculated using
the technique of automatic full field perfusion image
analysis (AFFPIA). The U Mann-Whitney test was used for
statistical analysis.
Results: Patients with exudative AMD revealed slightly
lower retinal blood flow than control subjects in area I
and in area II. In the AMD group total mean flow values
were: 295.75 AU/ 303.85 AU, while in the control group
were: 302.37 AU/ 304.42 AU. The mean velocity values
were: 1.48 AU/ 1.42 AU in AMD patients and: 1.49 AU/
1.52 AU in control group. The differences did not reach
the statistical significance.
Conclusions: The study results showed no changes in
retinal capillary blood flow in patients with exudative
AMD comparing to normal subjects. |
