ABSTRACT

Objetive: to demonstrate utility of microperimetry to the surgery of idiopathic macular hole, among 2010-2012, in the "Ramón Pando Ferrer" Cuban Ophthalmology Institute.
Methods: a longitudinal-prospective study of 17 patients who underwent surgery for idiopathic macular hole was carried out. The corrected visual acuity and microperimetry were studied before and after the surgery. If patient improved 2 lines or more of corrected visual acuity and if they having 2 of the items: disappearance of absolute scotoma, disappearance of scotoma relative, improvement of retinal sensitivity; were established improvement of them. Oftalmology exam and optic coherent tomography were studied before and after surgery, specifying the presence and close of the hole.
Results: 64,71 % of patients presented absolute scotoma and 94,12 % of them had relative scotoma. The mean retinal sensitivity was 8,40 ± 4,39 and fixation was stable in 81,82 % of them. Better preoperative mean retinal sensitivity showed statistical significance to best corrected visual acuity (p= 0,012). 72,73 % of patients with close surgical of the hole (64,71 %) improved corrected visual acuity (p= 0,006), and 54,55 % of them improved the microperimetry (p= 0,002). The anatomical closing of hole showed statistical significance for the improvement of corrected visual acuity (p=0,009) and for the improvement of microperimetry (p= 0,043).
Conclusions: the preoperative retinal sensitivity can predict the functional recovery of the macular hole. After close of the hole, the recovery of visual acuity can precede to improvement of microperimetry. Microperimetry can constitute a support point to continue the functional recovery.
