Abstract
- PURPOSE: To assess the intraocular pressure (IOP) and corneal endothelial changes, over a 6-month period, after a single injection of intravitreal triamcinolone (ivTA) in Chinese patients. METHODS: A total of 43 eyes of 43 consecutive Chinese patients with various macular diseases received a single bolus injection of 4 mg ivTA, of which, 14 eyes with significant cataracts underwent simultaneous phacoemulsification and primary intraocular lens implantation. IOP was measured preoperatively and weekly in the first month, and then monthly until 6 months postinjection. Specular microscopy was performed on 24 of the 29 eyes without simultaneous cataract surgery, preoperatively and at months 1, 3, and 6. RESULTS: All patients completed 6 months of follow-up. Nine out of 43 (20.9%) eyes had IOP>21 mmHg. Their mean maximum IOP was 29.2 mmHg (range 23.0–37.0), necessitating the use of 2.0 types of topical antiglaucomatous medications on average. The IOP elevation occurred at a mean of 5.2 weeks (range 1–17) postinjection. All IOPs returned to normal, without additional antiglaucomatous medications, by 6 months. There was no statistically significant difference (paired t-test, P<0.05) in the corneal endothelial cell count and other specular microscopy parameters up to 6 months after the injections. CONCLUSION: A single 4 mg bolus injection of ivTA appeared to have no harmful effects on the corneal endothelium. IvTA caused transient IOP elevations in 20.9% of Chinese patients, similar to that observed in Caucasians. As the IOP rise can occur as early as 1 week after the injection, early monitoring will help its early detection and prevent optic nerve damage.Eye (2005) 19, 625–630. doi:10.1038/sj.eye.6701585 Published online 28 May 2004 [ABSTRACT FROM AUTHOR]
