| Summary: |
The aim of the study was
to evaluate the applicability of retinal thickness
measurements using the Retinal thickness analyzer (RTA)
in diagnosis and monitoring treatment of a variety of
eye diseases.
Material and methods: Patients with various retinal
diseases (diabetic macular edema, branch retinal vein
occlusion, age-related macular degeneration, and primary
open-angle glaucoma), were examined for retinal
thickness in the posterior pole using the Retinal
thickness analyzer. A laser light beam of a 543 nm wave
length was projected on the retina and scanned across
3x3 mm retinal area. Five scans covered the 20° area of
the fundus. The images of the particular intersections
were digitally recorded and the results were presented
as colour maps and diagrams.
Results: The examination carried out with Retinal
thickness analyzer showed the retinal thickening in
patients with diabetic macular edema and branch retinal
vein occlusion. Leakage from subfoveal choroidal
neovascular membranes resulted also in retinal edema and
thickening. Fluorescein and indocyanine green
angiography confirmed the diagnosis. Evaluation of the
retinal nerve fibre layer in patient with primary open
angle glaucoma, confirmed a thinning of the retina in
the region of posterior pole.
Conclusions: The scanning Retinal thickness analyzer
provides an essential information useful in diagnosis
and monitoring treatment of retina diseases in the
macula region. |
