Brief Summary
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 indocyanine green (ICG) assisted inner limiting membrane ( ILM) peeling or vitrectomy plus trypan blue (tb) assisted ILM peeling. At baseline patients are characterized using early treatment diabetic retinopathy study (ETDRS) visual charts, tests of aniseikonia, optical coherence tomography 3 (OCT3), visual field 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 tb 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.

Limitations and Caveats
non-closure of macular hole after surgical procedure in 18 patients led to re-operation. Data included in main published papers.
