Abstract
Purpose: :
To determine the incidence of cystoid macular edema (CME) after combined phacoemulsification and pars plana vitrectomy in patients with uveitis.
Methods: :
The medical records were reviewed of patients with noninfectious uveitis who underwent combined phacoemulsification/pars plana vitrectomy between August, 2007 - July, 2011. Patients with diabetes or documented macular edema at the time of surgery were excluded. Cases were classified according to the presence of postoperative CME within 3 months after surgery.
Results: :
88 surgeries were enrolled. The incidence of postoperative CME was 13.6%. 12 eyes developed CME. Among patients who developed CME, 9 eyes (75%) had anterior uveitis, and 3 eyes (25%) had panuveitis. In non-CME group, 24 eyes (31.6%) had anterior uveitis, 7 eyes (9.2%) had intermediate uveitis, 5 eyes (6.6%) had posterior uveitis, 40 eyes (52.6%) had panuveitis. In the CME group, 4 eyes (33.3%) had history of previous CME, compared with 17 eyes (22.4%) in the non-CME group. In the CME group, 3 eyes (25%) had documented active inflammation within the 6-month period before surgery, compared with 24 eyes (31.6%) in the non-CME group. In the CME group, 9 eyes (75%) were treated with preoperative corticosteroids prior to surgery, compared with 68 eyes (89.5%) in the non-CME group. Four (33.3%) of the eyes that developed CME underwent procedure without intraocular lens implantation, while among patients who did not develop CME this figure was 10 (13.2%) eyes. By 3 months, 66.7% of patients in the CME group achieved visual acuity of 20/40 or better, while in the non-CME group this figure was 82.9%.
Conclusions: :
In this study of patients with uveitis, the overall incidence of CME after combined phacomulsification/pars plana vitrectomy was 13.6%.
