  Outcome Measures

1.  Primary:   Visual Acuity (ETDRS Letters)   [ Time Frame: Visual acuity at 12 months ]

2.  Secondary:   Anatomic Success   [ Time Frame: macular hole closure at 12 months ]

3.  Secondary:   Visual Field Defects   [ Time Frame: 6 months ]

  Serious Adverse Events

  Other Adverse Events

  Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
non-closure of macular hole after surgical procedure in 18 patients led to re-operation. Data included in main published papers.
