Purpose: To investigate the use of intravitreal injection of triamcinolone
acetonide (TA) for the treatment of refractory uveitic cystoid macular edem
a (CME).
Design: Prospective, nonrandomized, self-controlled comparative trial.
Participants: Six patients with chronic CME resistant to treatment with sys
temic steroids, orbital floor steroids, and cyclosporine A. Three patients
were followed for more than 1 year, and the other three for between 3 and 9
months,
Intervention: Injection of 2 mg of TA into the vitreous cavity,
Testing: Optical coherence tomography scanning of the fovea before and afte
r injection and logarithmic minimal angle of resolution visual acuity,
Main Outcome Measures: Visual acuity, retinal thickness, cystoid space heig
ht, and intraocular pressure.
Results: There was complete anatomic resolution of CME in five of the six c
ases within 1 week after injection. Cystoid spaces began to return between
6 weeks and 3 months after injection, Two patients with longer term follow-
up responded to further orbital floor steroid injection and had no CME 1 ye
ar later, One patient had raised intraocular pressure develop, requiring a
trabeculectomy. Mean improvement in visual acuity after 12 months was 0.27
(range, 0.14-0.42).
Conclusions: Complete anatomic and, to some extent, functional recovery can
be induced by intravitreal TA despite long-term refractory inflammatory CM
E, Optical coherence tomography aids in the management of these cases. (C)
