Official Title: Traumatic Macular Hole: Observation Versus Early Surgical Intervention, A Multicenter Randomized Controlled Trial

Further study details as provided by Peking University Third Hospital:

Primary Outcome Measures:
  • Change from Baseline in Best Corrected Visual Acuity [ Time Frame: 2week, 1month, 2month, 3month, 6month ] [ Designated as safety issue: No ]
  • Change from Baseline in Maximal Diameter of the Hole Shown on OCT [ Time Frame: 2week, 1month, 2month, 3month, 6month ] [ Designated as safety issue: No ]
  • Change from Baseline in Top Diameter of the Hole Shown on OCT [ Time Frame: 2week, 1month, 2month, 3month, 6month ] [ Designated as safety issue: No ]

Estimated Enrollment: 30
Study Start Date: January 2012
Estimated Primary Completion Date: December 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: obervation
Active Comparator: Surgical intervention (vitrectomy surgery) Procedure: vitrectomy surgery
"PPV+ILM peeling" done immediately after the identification of the macular hole


Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • closed globe injury
  • presence of full-thickness macular hole after trauma

Exclusion Criteria:

  • open globe injury
  • coexistence of idiopathic macular hole
  • severe opaque in the visual axis caused by the injury(eg. severe cataract, severe vitreous hemorrhage)
  • combined injuries requiring immediate surgical intervention (eg. lens dislocation, retinal detachment, cyclodialysis)
  • coexistence of high myopia
  • coexistence of choroidal rupture or subretinal hemorrhage within the diameter of 400μm from the center of the foveola
  • coexistence of severe optic nerve injury (no light perception, APD+)
