The use of active intraocular drying in macular holes surgery
Purpose: to design a method of active drying ofa fragment of internal limiting membrane (ILM) to achieve its strong adhesion to the retina in the surgical treatment of idiopathic macular hole (MH). Material and methods.The study included 10 patients (10 eyes) with large idiopathic MH. The best corrected visual acuity ranged from 0.03 to 0.1. All patients underwent active drying of inverted ILM fragment during MH surgical treatment by additional air supply through a long blunt cannula. The follow-up was up to 3 months after surgery. Results. The inverted ILM fragment retained a stable position without displacement or deformation, and had dense adhesion to the retina in all cases during the follow-up. According to SOCT, improvement of the anatomical condition of the retina in the foveal area was achieved in all patients; the closure of the MH with the preservation of the defect at the level of the ellipsoid zone of the photoreceptors of the retina was noted. Final visual acuity was from 0.2 to 0.4 (0.26±0.08 in average). Central sensitivity increased to 22.36 ± 2.29 dB, total sensitivity rose to 23.7 ± 1.43 dB. Absolute scotoma was found to disappear in the center of the fovea. Conclusions. Further investigations on larger clinical material are necessary for a reliable assessment of the effectiveness of the method.
