Several factors may help predict outcome of lamellar macular hole surgery
After lamellar macular hole surgery, poor visual outcome may be predicted by poor initial visual acuity, a disrupted inner segment/outer segment junction or a thin fovea, according to a study.
The retrospective review included 30 eyes of 30 consecutive patients who underwent vitrectomy for lamellar macular hole.
At a mean of 18 months after vitrectomy, visual acuity improved in 19 eyes with an overall mean improvement of one Snellen line of vision (P = .002).
Patients who preoperatively had an intact inner segment/outer segment junction (P = .003), a foveal thickness greater than 100 µm (P = .004) and a visual acuity better than 20/100 (P = .003) had the best outcomes.
The combination of preoperative visual acuity and the presence or absence of inner segment/outer segment disruption was the greatest predictor of final visual acuity (P < .001).
