The purpose of this study is to compare the anatomical and visual recovery of eyes with traumatic macular hole (TMH) following either early vitrectomy or 6-month observation.

Condition Intervention
Macular Hole
Procedure: vitrectomy surgery

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Single Blind (Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Traumatic Macular Hole: Six-months Observation Versus Early Surgical Intervention, A Multicenter Clinical Trial

Further study details as provided by Peking University Third Hospital:

Primary Outcome Measures:
  • macular hole closure rate [ Time Frame: 6 month after injury ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • central foveal thickness [ Time Frame: 6 month after hole closure ] [ Designated as safety issue: No ]
  • length of inner-segment outer-segment junction defect [ Time Frame: 6 month after hole closure ] [ Designated as safety issue: No ]
  • final visual acuity [ Time Frame: 6 month after hole closure ] [ Designated as safety issue: No ]

Enrollment: 44
Study Start Date: January 2012
Study Completion Date: June 2014
Primary Completion Date: February 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: obervation
patients in this arm received 6-months observation alone after injury
Active Comparator: Surgical intervention
patients in this arm received vitrectomy surgery as soon as possible after injury
Procedure: vitrectomy surgery
"pars plana vitrectomy +internal limiting membrane peeling" done immediately after the identification of the macular hole

Detailed Description:
Patients who received vitrectomy immediately after the injury were compared with patients who were observed for six months for spontaneously closure.The closure rate, foveal microstructure, and final visual acuity were analyzed.

Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • closed globe injury
  • identification of full-thickness macular hole by optical coherence tomography within one month 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, positive afferent pupillary defect)
