Correlation of visual acuity with central macular thickness in Diabetic macular edema

Dr. G. Premalatha, Dr P. Shyam Sundar

Abstract :

 AIM: to describe the correlation of central macular thickness with visual acuity (VA) in diabetic macular edema (DME) And various patterns of DME demonstrated by optical coherence tomography(OC T)

 

STUDY: observational case series.

 

METHODS: All patients with DME who had OCT scan and met with inclusion criteria were taken.

Central macular thickness (CMT) and VA were noted.

Type 1 : Diffuse retinal thickening (DRT),

Type 2 : cystoid macular edema (CME)

Type 3: DME With serous retinal detachment (SRD)

Type 4 : DME with Trational component{posterior hyloid traction (PHT)/epiretinal memane(ERM) /vitreous traction(VT)}

Type 5 : combination of above all patterns were noticed.

 

RESULTS: OCT scans of 98 eyes with DME were taken. In 98 eyes with DME, DRT (35.82%), CME (27.55%), DME with SRD(20.40%), DME with PHT/ERM/VT(12.23%) and combination of above patterns(4.08%) were observed. Mean retinal thickness and Mean VA varied with sub–groups and significant correlation present (at p<0.05%).Increasing CMT was significantly correlated with worse VA (at p<0.05%)

 

CONCLUSION: DME exhibits at least 5 different patterns on OCT and there is a negative correlation between CMT and visual acuity.
