Abstract

Purpose
To compare the axial length between patients with macular hole and a control group.
Methods
The axial length was compared and analyzed for 100 eyes of 100 patients diagnosed with idiopathic full thickness macular hole, fellow eyes of patients, and 100 eyes of 100 age-matched control subjects who underwent cataract surgery.
Results
The average axial length was 22.71 ± 0.92 mm in eyes of patients with macular hole and was 22.81 ± 0.89 mm in fellow eyes of patients. There was no significant difference between axial length of eyes with macular hole and fellow eyes of patients (p = 0.477). The average axial length was 23.37 ± 0.68 mm in the control group. There were statistically significant differences between the axial length of eyes with macular hole and fellow eyes of patients compared to that in the control group (p < 0.001).
Conclusions
Patients with idiopathic macular hole showed significantly shorter axial length compared to the control group, and this might be considered a triggering factor of macular hole.
