Purposes : To asses the pattern of diabetic macular edema (DME) with Optical Coherence Tomography (OCT) and to evaluate the relation between macular thickness with visual acuity and disease severity based on clinical findings.

Methods : Retrospective, observational study from medical record. The data was taken from Malang Eye Clinic. Clinical diagnosis, age, sex, best corrected visual acuity, macular edema pattern and macular thickness were recorded.

Results : In a total of 23 (46 eyes) patients we found 24 eyes with nonproliferative diabetic retinopathy, 5 eyes with Pre proliferative diabetic retinopathy, and 12 eyes with proliferative diabetic retinopathy. Optical coherence tomography found different patterns of structural changes in DME : 7 eyes with sponge-like retinal swelling (26.3%) and 6 eyes with cystoid macular edema (36.84%). The rest had more than one pathological changes. Mean macular thickness were lowest in NPDR (212±101.96 µm) and highest in PDR (366.6±21µm µm). There is correlation between macular thickness and visual acuity ( r:0.33, p:0.035).

Conclusions : There are many pattern of DME described using OCT. Assesment of macular thickness using OCT were coherent with severity of the disease and level of visual impairment, but incoherent with severity of the disease.
