Effects of Macular Buckle Versus Vitrectomy on Macular Hole and Macular Detachment in Highly Myopic Eyes

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT03433547
Recruitment Status : Completed
First Posted : February 14, 2018

Brief Summary:
Full-thickness macular Hole associated with macular detachment is a one of the maculopathies of high myopia. There is controversy in the primary treatment for this situation. This study will compare the effects of macular buckling versus vitrectomy in a cohort of highly myopic eyes with this situation.

Condition or disease Intervention/treatment Phase
Macular Holes High Myopia Macular Detachment Procedure: Buckle Procedure: Vitrectomy Other: Limbal paracentesis Other: Gas injection Other: Peeling internal limiting membrane Other: Gas tamponade Not Applicable

Detailed Description:
A randomized, open label, single center study comparing the efficacy of macular muckle + gas injection versus internal limiting membrane peeling + gas tamponade on full-thickness macular hole associated with macular detachment in eyes with high myopia.

Arm Intervention/treatment
Experimental: Buckle
Macular buckling, Limbal paracentesis, and intraocular gas injection.
Procedure: Buckle
Surgical procedures of macular buckling
Other Name: Implantation of a device of macular buckling

Other: Limbal paracentesis
Drainage of aqueous fluid (0.1-0.2 ml) through limbal paracentesis

Other: Gas injection
Inject gas ( C3F8 100%, 0.2ml-0.3ml) into vitreous cavity through pars plana.

Active Comparator: Vitrectomy
Vitrectomy, peeling internal limiting membrane, and gas tamponade.
Procedure: Vitrectomy
Surgical procedures of small gauge vitrectomy

Other: Peeling internal limiting membrane
Peeling internal limiting membrane with forceps

Other: Gas tamponade
Filling the vitreous cavity with gas (C3F8, 14%)

Primary Outcome Measures :
  1. Retinal re-attachment rate [ Time Frame: 1 month ]
    Successful rate of reattachment of macular retina after surgery

Secondary Outcome Measures :
  1. Macular hole status [ Time Frame: 3 month ]
    Closure rate of macular hole after surgery on optical coherence tomography

  2. Post-operative best corrected visual acuity [ Time Frame: 3 month ]
    Best corrected visual acuity of the eyes after surgery
