PURPOSE: This study investigated firstly the change of intraocular pressure (IOP) after injection of intravitreal triamcinolone acetonide (IVTA) for the treatment of macular edema and secondly the factors that influence these changes. METHODS: A prospective, non-comparative study was performed in 60 patients at Kangnam Sacred Heart Hospital from October 2003 to September 2004. All the patients received 4-mg IVTA injection. RESULTS: Mean IOP was elevated from the day after injection and peaked at 20.5 mmHg after 2 months (p=0.000). Twenty-six eyes (43.3%) showed significant IOP elevation. IOP was not controlled despite full glaucoma medication in 7 (11.7%) eyes. Two eyes underwent filtering surgery. Younger age was a statistically significant predictive factor for IOP elevation (p=0.009). CONCLUSIONS: In this study, patients who needed filtering surgery developed an IOP spike within one week after the injection. Therefore, clinicians should consider checking IOP at the end of the first week. Furthermore, greater cautions is mandatory with relatively younger patients.

PURPOSE: To assess the effect of intravitreal and posterior subtenon injections of triamcinolone acetonide (TA) on intraocular pressure (IOP). METHODS: we reviewed 42 consecutive eyes after intravitreal TA injection (IVTA) and 43 eyes following posterior subtenon TA injection (PSTA). All cases had a minimum follow-up time of three months. After injection, the value and time of the maximal IOP, the amount of IOP elevation and the needs of the medication were assessed. RESULTS: The IOP increased significantly (p<0.001) from 16.3+/-2.5 mmHg preoperatively to a mean maximum of 21.7+/-5.3 mmHg in the IVTA group, and from 15.3+/-4.5 mmHg to 20.6+/-3.0 mmHg in the PSTA group. An elevation in the IOP of more than 5 mmHg from the baseline IOP was seen in 52.4% of the IVTA group at a mean time of 3.1 weeks postoperatively, and 44.2% of the PSTA group displayed an IOP elevation at 5.9 weeks. CONCLUSIONS: Both developed significant elevations of IOP, but this appeared at a later date in the PSTA group. Careful follow-up after local injection of steroids is necessary.

PURPOSE: To compare the effect of early versus late intravitreal injection of triamcinolone in patients with macular edema due to branch retinal vein occlusion (BRVO). METHODS: Twenty eyes of 20 patients with macular edema from BRVO, including 10 with duration after onset of < or =3 months and 10 with duration of >3 months, were treated using a single intravitreal triamcinolone injection (4 mg/0.1 ml). Best-corrected visual acuity and foveal thickness by optical coherence tomography were measured 1, 3, and 6 months post-injection. RESULTS: In patients that received treatment after a disease duration of < or =3 months, visual acuity and foveal thickness significantly improved from baseline over 6 months of follow-up. However, in those with a duration of >3 months, improvements in visual acuity and foveal thickness, though apparent at 1 month, were not maintained at 3 and 6 months post-triamcinolone. CONCLUSIONS: Intravitreal triamcinolone is more effective in patients with BRVO who are treated earlier.
