Purpose:
To report the outcome of epiretinal membrane (ERM) surgery in young patients.
Design:
Interventional case series study.
Method:
A retrospective review of 20 young patients who had undergone vitrectomy and epiretinal membrane removal. All patients had a preoperative examination, including fundus biomicroscopy, red free photographs, and fluorescein angiography.
Results:
Nine patients were males and 11 females (age: 7-26 years; mean: 16.3 years). Follow up ranged from 4-96 months (mean: 21.2 months). The 20 patients comprised 13 cases of idiopathic ERM, six cases in which ERM was associated with ocular inflammation and one case of combined hamartoma of the retina and retinal pigment epithelium (RPE). In 13 cases, the ERM was especially white, thick, and opaque, with localized constriction and severe retinal distortion. Final best-corrected visual acuity (VA) was significantly better than preoperatively (20/50 vs. 20/112), (P = 0.0002). Mean improvement in VA was 4.25 lines and 17 patients gained two or more lines. This improvement was better in secondary than idiopathic ERM (6 lines vs. 3.3). During follow up, five cases of recurrence were observed (25%). In another case, postoperative persistent ocular hypertension required filtering surgery.
Conclusion:
The characteristics of ERM in young patients are quite different in many cases from those in adults in terms of thickness and adherence. Removal of ERM in young patients is feasible and safe although the membrane may focally adhere strongly to retinal vessels. VA usually improves significantly after surgery, but recurrences are more frequent than in adults.
