Purpose

To describe the changes in central macular thickness (CMT) and central macular volume (CMV) values in patients with idiopathic epiretinal membrane (ERM) along follow-up time.

Setting/Venue

University of Health Sciences, Ulucanlar Eye Research and Education Hospital.

Methods

A cross-sectional case study includes 115 Caucasian subjects with idiopathic ERM who had no underwent vitreoretinal surgery. 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.

Results

The mean age of the subjects was 64.9 ± 7.9 years (54-77). The male to female ratio was 51/64. The mean baseline CMT and CMV values were 322.8 ± 86.6 m (204-633) and 9.2 ± 1.2 m3 (6.6-14.3). The mean follow-up time was 44.4 ± 30.1 months (6-132). The mean final CMT and CMV values were 339.9 ± 120.1 m (207-957) and 8.7 ± 1.1 m3 (5.6-11.7). The mean change in CMT and CMV values were 17.3 ± 128.4 m (-216-687) and -0.4 ± 1.3 m3 (-4.7-1.9).

Conlusions

After a long-time follow-up, CMT is tend to increase despite of being CMV is tend to decrease in patients with idiopathic ERM.
