Purpose:
To evaluate the role of vitrectomy in patients with persistent, visually disabling vitreous opacities.
Methods:
Six consecutive eyes of five men (age 58-66 years) with pseudophakia or aphakia and vitreous opacities resulting in visual symptoms for more than 1 year that underwent vitrectomy were retrospectively reviewed. Postoperative questionnaires regarding functional performance and quality-of-life issues were completed by the participants to assess subjective patient satisfaction.
Results:
Postoperative Snellen visual acuity was improved or equal to preoperative acuity in all cases (8-44 month follow-up) and there were no surgical complications. All patients expressed high satisfaction with overall visual function. Analysis of the National Eye Institute Visual Function Questionnaire-39 indicated that general vision, near activities, distance activities, mental health, role difficulties, and peripheral vision were significantly improved (P < 0.05) following surgical intervention.
Conclusions:
Vitrectomy may be indicated in a select group of patients with visually disabling vitreous floaters, although objective assessment of visual dysfunction from vitreous floaters requires further evaluation.
