Abstract Details

Purpose:

To investigate, with optical coherence tomography (OCT) swept source (tritón), the relationship between the deposit of the retinal pigment epithelium (RPE) preoperative affects the postoperative visual outcome in eyes with surgically closed macular holes (MH).

Setting:

Prospective intervencional case series, September 2015-February 2017 Hospital Universitario Vall d’hebrón, Barcelona Spain

Methods:

Prospective interventional case series. Thirty- eight eyes of 38 patients with an idiopathic MH were studied. Preoperative status of the RPE at the base of the hole was evaluated with DRI OCT Tritón. Pars plana vitrectomy, with the removal of the internal limiting membrane was performed, in all cases. Foveal microstructure, best visual acuity and presence of RPE deposit in MH was determined by swept source optical coherence tomography (OCT) Tritón before and at 3 and 12 months postoperatively.

Results:

All MHs were successfully closed. The mean age of patients was 70,3 years. Settings as height (mean: 412,87 μm), minimal (mean: 444,32 μm) and the base (mean: 874,08 μm ) diameters of the MH were significantly langer at baseline, 3 and 12 months in the eyes with RPE deposit ( P < 0,001; Mann-Whitney U test). The best corrected visual acuity was significantly worse at baseline, 3 and 12 months postoperatively in eyes with RPE deposit (P< 0,001; P<0,005; P<0,005; Mann-Whitney U test).

Conclusions:

Preoperative RPE deposit in MH treated surgically was significantly correlated with a worse visual acuity and a poorer recovery of Foveal microstructure at baseline, 3 and 12 months.
