To compare central macular thickness (CMT) and central macular volume (CMV) outcomes in idiopathic epiretinal membrane (ERM) with and without additional vitreomacular interface abnormality (VMIA).
University of Health Sciences, Ulucanlar Eye Research and Education Hospital.
A cross-sectional case study includes 55 idiopathic ERM subjects (Group 1) and 32 idiopathic ERM subjects with additional VMIAs including vitreomacular traction and lamellar hole. The baseline and final spectral domain optical coherence tomography (Spectralis, Heidelberg, Germany) biomarkers including CMT and CMV were investigated. The change in CMT and CMV along follow-up time were calculated. The outcomes of the two groups were compared.
The mean age of the subjects was 61.3 ± 6.8 years (54-74) in Group 1 and 63.5 ± 7.1 years (56-77) in Group 2 (p =0.768). The mean follow-up time was 41.5 ± 31.6 months (6-132) in Group 1 and 52.7 ± 34.5 months (12-108) in Group 2 (p =0.097). The mean change in CMT and CMV values were 31.7 ± 141.4 mm (-196-687) and 0.3 ± 1.3 mm3 (-1.9-4.6) in Group 1 and -24.1 ± 75.3 mm (-216-99) and 0.8 ± 1.4 mm3 (-1.0-4.7) in Group 2 (p =0.062 and p =0.217, respectively).
After a long-time follow-up of subjects with idiopathic ERM, presence of additional VMIA has no effect on optical coherence tomography biomarkers including CMT and CMV.
