| Summary: |
Purpose: The aim of
the study was to evaluate choroidal circulation in the
posterior pole of the eye in diabetic patients with
nonproliferative retinopathy.
Material and methods: Angiographic evaluation of
choroids in the posterior pole were performed in
diabetic patients with clinically detectable diabetic
retinal changes in the Department of Ophthalmology,
Medical Center of Postgraduate Education in Warsaw from
December 2002 to December 2004, using HRA-system
(Heidelberg Engineering, Germany). HRA-system allows to
perform simultaneous fluoresceine (FA) and indocyanine
green (ICGA) angiography.
Results: Simultaneous ICGA and fluorescein
angiography pictures were evaluated. Choroidal
abnormalities were defined as ICGA findings not
detectable by FA. In ICGA we observed hypo- and
hyperfluorescent areas or spots in different phases of
the examination which proved break-down of outer
blood-retinal barrier, retinal pigment epithelial oedema,
increased permeability of choriocapillaries and
chorioidal microaneurysms.
Conclusions:
1. FA discloses only a part of vascular pathology in
posterior pole of the eye in the course of diabetes.
2. ICGA may be useful as adjunctive to FA in the
evaluation of the choroidal vascular changes in diabetic
eyes.
3. Choroidal vessels changes may play role in the
development of diabetic retinopathy. |
