ABSTRACT
Objectives:
To assess changes in reflectivity of the retinal pigment epithelium (RPE), ellipsoid zone (EZ), and external limiting membrane (ELM) on spectral domain-optical coherence tomography (SD-OCT) images and the effects of reflectivity changes on visual acuity improvement after vitrectomy in macular hole patients. Materials andMethods:
Twenty-four eyes of 24 patients with idiopathic full-thickness macular hole closed after vitrectomy were retrospectively reviewed. The "plot profile" function of the medical imaging software was used by a single masked physician to analyze RPE, EZ, and ELM reflectivity on OCT images at postoperative 1 month and 12 months.Results:
Absolute and relative EZ reflectivity showed highly significant increases at postoperative 12 months compared to 1 month (p<0.001 and p<0.001, respectively). Absolute and relative EZ reflectivity changes from postoperative month 1 to month 12 after macular hole surgery were significantly correlated with best corrected visual acuity improvement (p=0.012 and p=0.020, respectively).Conclusion:
EZ reflectivity can be a predictor of functional and anatomical improvement after macular hole surgery.Palabras clave
