Abstract:

Objective To evaluate the efficacy of vitrectomy combined with intraocular tamponade of room air on the IV stage idiopathic macular hole. Design Retrospective case series. Participants Ten eyes of 10 patients with IV stage idiopathic macular hole underwent vitreoretinal surgery. Methods All the patients had undergone the examinations of best corrected visual acuity (BCVA)，intraocular pressure，slit lamp microscope, indirect ophthalmoscope, ultrasonic scan, fundus photographs and optical coherence tomography (OCT)． A standard 3-port pars plana vitrectomy (23-gauge system) was performed in all patients, and fill with room air in the vitreous cavity at the end of the operation to auxiliary press the retina． The follow-up duration varied from 9 to 107 days. Main Outcome Measures The BCVA, retinal reattaehment and the complications． Results At the latest follow-up， 9 eyes(90％) were anatomically reattached, 1 eyes (10％) was partly anatomically reattaehed，no eye was not reattached; postoperative BCVA improved in 6 eyes (60％)，unchanged in 3 eyes (30％)，and decreased in 1 eyes(10％). Conclusion This small sample study shows that the vitrectomy combined with tamponade of room air can effectively treat IV stage idiopathic macular hole without ocular complications．
