| Summary: |
Purpose: Aim of the
study is an evaluation of the anatomic state of retina
in the macular region in diabetic patients with various
stages of retinopathy by using RTA analyzer, and an
assessment of applicability of this method in early
diagnosis of diabetic macular edema.
Material and methods: Forty diabetic patients (68
eyes) underwent full ophthalmologic examination and also
retinal thickness analysis with RTA analyzer. In
particular, foveal average thickness FAV and posterior
pole average thickness PPAV were determined. The data
were statistically evaluated.
Results: Both FAV and PPAV are strongly
correlated with the eyeground state and increased with
increasing the severity of retinopathy and macular edema.
The patients with minimal and mild nonproliferative
retinopathy without any visible macular edema showed an
increased retinal thickness when compared both with
diabetic patients without any retinopathy and with
control patients. The thickness was however lower than
that in patients with diabetic macular edema.
Conclusions: The eyes with minimal and mild
nonproliferative diabetic retinopathy without any
visible macular edema should be examined by some
independent methods, like RTA. The method can be
recommended for screening the macular edema in diabetic
patients. |
