Abstract

PURPOSE: Recently diffuse diabetic macular edema has been morphologically classified by optical coherence tomography. This study was conducted to examine the difference of risk factors of the classified types of diffuse macular edema.
METHODS
The subjects included 93 people who were diagnosed with non-insulin dependent diabetes. We diagnosed the presence of diabetic macular edema with slit lamp fundus examination and used OCT for the classification of diffuse macular edema. We examined the differences in epidemiological risk factors in non-diabetic macular edema patients after diabetic macular edema patients were examined with fluorescein angiography to confirm diffuse macular edema.
RESULTS
Diabetic macular edema was classified into 4 types using OCT. Compared with patients without macular edema, sponge-like macular edema - related epidemiological risk factors included diabetic nephropathy, cystoid macular edema was related to HbA1c, serous macular detachment was related to treatment of diabetes by insulin, and posterior hyaloid raction was related to diastolic blood hypertension.
CONCLUSIONS
In the present study, differences in epidemiological risk factors were related to the occurrence of a type of diffuse macular edema.
