Abstract
Purpose.To evaluate the effect of various factors on the prognosis of functional outcome after surgical treatment of large macular holes. Materials and methods. The results of surgical treatment of idiopathic macular holes (over 400 µm) in 47 patients (47 eyes) were analyzed. Endovitreal intervention of 25 or 27 G was performed with removal of epiretinal membrane and air tamponade. Results. Mean values of the best corrected visual acuity (BCVA) and retinal photosensitivity have been significant improved postoperatively: BCVA – from 0,12 ± 0,1 to 0,24 ± 0,18 (p<0,01), photosensitivity – from 20,07 ± 3,85 dB to 21,43 ± 3,44 dB (p<0,05). The mean value of the predicted BCVA according to the maximum hole diameter was 0.21 ± 0.0898. There was no dependence of BCVA on patients' age, duration of macular hole (more than 6 months) and anterior-posterior eyeball size (p<0.05). Conclusion. Prediction of visual acuity after surgery is dependent by the initial retinal photosensitivity in the macular zone as well as the maximal diameter of the macular hole. Key words: idiopathic macular hole, microperimetry, vitrectomy, optical coherence tomography
