Brief Summary:
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 or disease Intervention/treatment Phase
Trauma Macular Hole Procedure: vitrectomy surgery Not Applicable

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.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 44 participants
Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: Single (Outcomes Assessor)
Primary Purpose: Treatment
Official Title: Traumatic Macular Hole: Six-months Observation Versus Early Surgical Intervention, A Multicenter Clinical Trial
Study Start Date : January 2012
Actual Primary Completion Date : February 2014
Actual Study Completion Date : June 2014

Arm Intervention/treatment
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

Primary Outcome Measures :
  1. macular hole closure rate [ Time Frame: 6 month after injury ]

Secondary Outcome Measures :
  1. central foveal thickness [ Time Frame: 6 month after hole closure ]
  2. length of inner-segment outer-segment junction defect [ Time Frame: 6 month after hole closure ]
  3. final visual acuity [ Time Frame: 6 month after hole closure ]

Ages Eligible for Study:   Child, Adult, Older Adult
Sexes Eligible for Study:   All
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)
