  Purpose

The project is a randomized clinical trial with a follow up time of 12 months comparing the effects of surgical treatment of idiopathic macular holes. Patients are randomized to vitrectomy alone, vitrectomy plus ICG-assisted ILM peeling or vitrectomy plus Trypanblue-assisted ILM peeling. At baseline patients are characterized using ETDRS visual charts, tests of aniseikonia, OCT3, autoperimetri and fundus photography. Per- and postoperative complications are registered.

Data analyses will help clarify the effect of ILM peeling on hole closure and visual acuity. Comparing results after ICG- and Trypanblue-assisted ILM peeling will help clarify the topic of a toxic effect on retinal cells after staining and peeling of the ILM. Changes in intraretinal morphology before and after dye-assisted ILM peeling will be studied using OCT3 imaging and the patients' subjective opinion on the surgical results will be analyzed using quality of life questionnaires and metamorphopsia tests.
