Outcome Measures

Primary Outcomes (1)

  • macular hole closure rate

    6 month after injury

Secondary Outcomes (3)

  • central foveal thickness

    6 month after hole closure

  • length of inner-segment outer-segment junction defect

    6 month after hole closure

  • final visual acuity

    6 month after hole closure

Study Arms (2)

obervation

NO INTERVENTION

patients in this arm received 6-months observation alone after injury

Surgical intervention

ACTIVE COMPARATOR

patients in this arm received vitrectomy surgery as soon as possible after injury

Procedure: vitrectomy surgery

Interventions

"pars plana vitrectomy +internal limiting membrane peeling" done immediately after the identification of the macular hole

Surgical intervention

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • closed globe injury
  • identification of full-thickness macular hole by optical coherence tomography within one month after trauma

You may not qualify if:

  • 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)
