Optical coherence tomography in diabetic macular edema: sub-retinal fluid pattern and related risk factors.

In a retrospective cross-sectional study, we too evaluated the systemic risk factors associated with sub-retinal fluid (SRF) pattern of DME. We compared 37 eyes with SRF pattern of DME (designated cases) versus 30 eyes having DME (sponge like retinal swelling or cystoid macular edema) without SRF (designated controls) on spectral domain-OCT. We too found that the SRF pattern was more common in males than in females (84.8 % of cases were males versus 66.7 % of controls). We did not find an association of HbA1C (mean HbA1C of 6.73 in cases versus 6.71 in controls, p = 0.859) and anemia (mean Hb of 10.71 in cases versus 11.77 in controls, p = 0.118) with the SRF pattern of DME.
