Abstract:
Objective To investigate the efficacy and safety of intravitreous injection with triamcinolone acetonide (TA) for cystoid macular edema (CME) due to central retinal vein occlusion (CRVO). Methods Fourteen eyes of 14 patients with CME due to CRVO underwent intravitreous injection with 0.1 ml TA (40 mg/ml). Best-corrected visual acuity, intraocular pressure (IOP), slitlamp examination, fundus fluorescein angiography, and optical coherence tomography (OCT) were performed on the patients before and after the injection. The follow-up period was 10-22.4 months, with the mean of 15.9 months. Results The average visual acuity was 0.1 before the treatment; while 1 month and 3 months after the injection, the visual acuity of all of the patients improved, including ≥0.2 in 71.43% and 63.6% of the patients, respectively, and ≥0.5 in 42.9% and 27.3%, respectively. After then, the visual acuity of some patients decreased, and in the final visit, 4 eyes (28.6%) had a visual acuity of ≥0.2, and 1 eye (7.1%) of ≥0.5. Compared with that before the treatment, the visual acuity of 10 (71.4%) eyes improved and 4 (28.6%) eyes declined. One month after the treatment, the macular edema disappeared in 10 eyes (71.4%) and alleviated in 4 (28.6%). In the final visit, macular edema disappeared in 4 eyes, alleviated in 9, and aggravated in 1. In the follow-up duration, high IOP [22.3-40.1 mm Hg (1 mm Hg=0.133 kPa)]. In the final visit, posterior subcapsular cataract was found in 7 eyes. Conclusion Intravitreous injection with TA may be effective in reducing CME and enhancing the visual acuity in a short term with high IOP in some eyes. In the long-term follow-up period, the rate of recurrence of CME and incidence of posterior subcapsular cataract is high.
