Submacular Surgery Trials (SST)
To determine whether surgical removal of subfoveal choroidal neovascularization (CNV) and associated hemorrhage in patients with age-related macular degeneration (AMD), the ocular histoplasmosis syndrome (OHS), or idiopathic CNV stabilizes or improves vision more often than observation.
To determine how surgical removal compared to observation of subfoveal CNV due to AMD, OHS, or idiopathic causes changes the patient's perception of health- and vision-related "quality of life," as measured by telephone interview using the Medical Outcomes Survey Short Form-36 (MOS SF-36) instrument, the Hospital Anxiety and Depression Scale, and the National Eye Institute Visual Function Questionnaire (NEI VFQ-25).
To determine whether randomized trials of surgery are warranted for patients with subfoveal CNV associated with age-related macular degeneration not suitable for laser treatment.
