Inverted ILM-flap Techniques Variants for Macular Hole Surgery: Outcomes Comparison

Comparing Retinal Sensitivity and Fixation Stability of Inverted ILM-flap Techniques Variants for Macular Hole Surgery

To report closure rate, Best Corrected Visual Acuity (BCVA), Retinal Sensitivity (RS) and Fixation Stability (FS) of idiopathic Macular Holes (MH) randomized to Cover Group (CG) or Fill Group (FG) of the Inverted Internal Limiting Membrane (ILM) flap surgical procedure.

Patients will be randomized (1:1) to receive a vitrectomy with either Cover or Fill ILM flap technique. "Cover" when the ILM flap is everted over the MH gap in a single layer, "Fill" when the ILM is folded into multiple layers within the MH. All patients will undergo BCVA, RS and FS assessment at baseline, 1-month and 3-months after surgery.

Purpose of the study is to report retinal differential sensitivity and fixation stability as well as anatomic and visual outcomes of patients operated on for idiopathic MH and randomly assigned to Fill or Cover Groups.

Inclusion Criteria:

• patients with idiopatic macular holes

Exclusion Criteria:

• Patients with MH duration greater than 6 months
• myopia exceeding 6 diopters
• history of trauma
• previous ocular surgery except uncomplicated cataract extraction with in-the-bag IOL implantation
• any ocular illness including glaucoma, uveitis, optic nerve pathology
