Abstract
Purpose :
The aim of the present study was to describe pre and postoperative anatomical and Optical Coherence Tomography (OCT) features of patients who underwent macular hole surgery in a single academic center. The secondary objective was to investigate the association between preoperative parameters and post-operative visual acuity.
Methods :
This was a retrospective study of 54 patients who underwent macular hole surgery for the first time and who had no other ocular medical or surgical past history. The procedure was performed by four surgeons between July 2012 and August 2014. The clinical parameters such as gender, age, side, duration of symptoms, preoperative visual acuity in logMAR and lens status were collected. The macular holes were graded in agreement with the International Study Group Vitreomacular Traction classification. A Spectral-Domain Optical Coherence Tomography was carried out before every surgery. The OCT features were screened by a trained investigator. The size of the macular hole, the height, the right and left arm lengths, the basal diameter and the defect of the ellipsoid line and the COST line length were collected. We calculated OCT indexes (the Macular Hole Index, the Tractional Hole Index and the Hole Form Factor). The postoperative visual acuities at 1, 6 and 12 months were collected in logMAR. A cataract surgery when needed was also recorded.
Results :
The median [IQR] age was 66 [63-76]. There were 39 primary and 15 secondary macular holes (high myopia and post-traumatic). The median preoperative visual acuity was 0.70 [0.6-1.0] logMAR and the size of macular holes was 385 [252-533] µm. The closure rate was 89% with one surgery. Among the thirty-six phakic patients, 21 underwent cataract extraction within 8 [4-11] months after macular hole surgery. Postoperative visual acuity at 12 months was significantly associated with baseline visual acuity, r = 0.73, p <0.01 and with the size of the macular hole, r = 0.52, p < 0.01.
Conclusions :
The small size of our sample did not allow us to determine prognostic factors for functional outcomes one year after macular hole surgery. However this preliminary descriptive study provides us an interesting basis for undertaking a multicenter study.
