Resumo
Purpose: To measure, using the retinal thickness analyzer,
the mean foveal thickness and the mean perifoveal thickness
values on patients suffering from mild non-proliferative dia-
betic retinopathy without clinically detectable macular ede-
ma (classified by the ETDRS study), and compare them with
healthy individuals. Methods: Observational analytical re-
trospective case-controlled study, on a sample of 79 eyes (39
affected and 40 control). The sample was selected from by
exams previously taken at Centro Brasileiro de Cirurgia de
Olhos (CBCO) (from 1999 to 2003) stored in the retinal thi-
ckness analyzer. The control group was selected according
to specific criteria. The affected group was formed according
to the research inclusive and exclusive criteria. The results
were submitted to statistical tests for reliability. Results: In
the control group the values obtained for mean foveal thick-
ness were around (mean=147.4 micra ± 15.4 micra standard
deviation) and for mean perifoveal thickness were around
(mean=193.8 micra ± 24.6 micra standard deviation). Pa-
tients with mild non-proliferative diabetic retinopathy presen-
ted foveal thickness around (mean=198.9 micra ± 48.3 micra
standard deviation) and perifoveal thickness around (mean=
194.2 micra ± 26.4 micra standard deviation). Conclusion: An
increase of mean foveal thickness on diabetic patients who
have not shown clinical signs of macular edema was noted,
which was proved by statistical tests. Such results are simi-
lar to the values found in medical literature.
