AGE-RELATED CLINICAL OUTCOME AFTER MACULAR HOLE SURGERY

Abstract

Purpose: To evaluate functional and anatomical retinal recovery according to patient age using spectral domain optical coherence tomography in eyes with surgically closed macular holes.

Methods: We retrospectively studied 83 eyes with anatomically closed idiopathic macular holes after surgery confirmed by spectral domain optical coherence tomography. Patients were divided into four subgroups based on age (Group 1: ≤ 60, Group 2: 61-65, Group 3: 66-70, Group 4: > 70). Best-corrected visual acuity and reconstruction of the external limiting membrane and ellipsoid zone after surgery were documented for 12 months.

Results: Mean patient age was 64.5 ± 9.8 years (range 44-81). Mean visual improvement in logMAR units (ETDRS letter score) at 12 months was worse in older age subgroups (Group 1: 0.4 ± 0.3 [20], Group 2: 0.4 ± 0.3 [20], Group 3: 0.2 ± 0.3 [10], Group 4: 0.1 ± 0.3 [5], P = 0.001). When age was more than 65 years, total number of eyes with restored retinal microstructure after surgery was lower (22 eyes, 53.7%; 32 eyes, 76.2%; P = 0.018) and time (months) to structural recovery was longer (10.2, 7.1, P < 0.001) than age under 65 years. Visual improvement corresponded to recovery of the outer retinal layers. In multivariate analysis, patients of older age (odds ratio, 0.91; 95% CI, 0.89-0.93) had less visual improvement at month 12.

Conclusion: Poor visual outcomes and delayed microstructural recovery occurred in older subjects after anatomically closed macular hole surgery. Older age may be indicative of poor clinical outcome in repaired macular holes.
