Correlation between macular thickness and volume with visual acuity in diabetic macular edema by using domain optical coherence tomography.

ABSTRACT

Introduction: To investigate the correlation between Macular thickness and Volume with Bestcorrected visual acuity (BCVA) in eyes with Diabetic macular edema and Type 2 diabetes. Materials and Methods: A retrospective study including 60 eyes of 60 patients evaluating Retinal thickness and macular volume measured with Spectral Domain Optical Coherence Tomography and best corrected visual acuity was measured with the Snellens Chart. Results: There is significant increase in the macular thickness and macular volume with decrease in the best corrected visual acuity. Conclusion: Diabetic macular edema causes decrease in visual acuity due increase in macular thickness and volume.
