Optical coherence tomography [OCT]; findings and visual acuity [V/A] in diabetic macular edema [DME] patients

ABSTRACT

To see the consequences of diabetic macular edema as assessed by optical coherence tomography [OCT] and visual acuity [V/A]. A prospective observational study. Patients were selected by simple random technique. Jan 2012 - Dec 2013. A total of one hundred patients [200 eyes] of ages forty two to sixty three years with an average age of 51.04 +/- 6.26 years of either sex were included. All these patients were examined in the outpatient department and were diagnosed as diabetic with macular edema and no opacity in refractive media. Their V/A was checked. OCT was performed in the Diagnostic and Research Centre, Department of Ophthalmology, Allied Hospital, Faisalabad. Out of 200 eyes on OCT our findings were Diffuse Retinal Thickening in 199 eyes [99.5%], Cystoid Macular Edema in 119 eyes [59.5%], Subretinal Fluid in 48 eyes [24%], Epiretinal Membrane in 15 eyes[7.5%], Vitreomacular Traction in 11 eyes [5.5%] and Taut Posterior Hyaloid Membrane in 4 eyes[2%]. The visual acuity on the right side was 0.29+/-0.19 and on left side it was 0.38+/-0.11. The macular thickness was 437.10+/-82.57 microns on the right side and 414.01+/-69.35 microns on the left side. The best-corrected visual acuity was significantly correlated with central foveal thickness. Our results showed, on the right side, a significant negative correlation [correlation coefficient -0.355, p<0.01] between them. On the left side, a significant negative correlation [correlation coefficient -0.362, p<0.01] was recorded
