Abstract: Purpose: To evaluate the effect of vitreo macular interface changes on serous macular detachment in diabetic macular edema (whether spongy-like or cystoid). Methods: This study involved 281 eyes with diabetic macular edema and serous macular detachment. Complete ophthalmic examination, fundus fluorescein angiography (FFA) and optical coherence tomography (OCT) were done. Heidelberg Spectralis OCT was used to examine all eyes and scans were done on horizontal, vertical and twelve radial planes through the centre of the fovea. The height of serous macular detachment was measured with a caliper in all eyes & the state of vitreo macular interface was reported. Results: Of the 281 eyes with diabetic macular edema & serous macular detachment (SMD), spongy-like DME was reported in 213eyes (75.8%) and cystoid DME in 68 eyes (24.2%). With Spectralis OCT, serous macular detachment was shown as neuro-sensory retinal elevation over non-reflective cavity with minimal shadowing of the underlying structures. The height of serous macular detachment was measured with a caliper & the state of vitreo macular interface was reported. Conclusions :Spectral domain optical coherence tomography plays a major role in the diagnosis of DME with SMD & provides detailed description of the associated vitreo macular interface changes. In our reported cases vitreo macular interface changes did not play a major role in the pathogenesis of SMD with DME as 68.33% with DME & SMD had no VM interface tractional changes. Further study on a larger number of cases is recommended to determine the role of vitreomacular interface changes in the development of SMD in eyes with DME.
