Intravitreal triamcinolone acetonide (IVTA) is a commonly employed treatment for various vitreoretinal disorders. However, approximately 23% to 50% of patients who receive IVTA develop ocular hypertension after the drug is injected into the eye. Similar to IVTA, topically administered corticosteroids eye drops result in ocular hypertension in approximately 33% of the population. It is unknown whether identifying patients who develop ocular hypertension from topical corticosteroids could be used to identify patients who are at risk for injectable IVTA. Therefore, the purpose of this study is to evaluate the efficacy of topical prednisolone 1% four times daily for one month as a screening test to reduce the incidence and severity of ocular hypertension after IVTA injection.

Further study details as provided by Hotel Dieu Hospital:

Primary Outcome Measures:
  • To detect a 60% or greater decrease of developing ocular hypertension (>20 mmHg) in the group of patients who received a trial of prednisolone 1% gtts x 4 weeks, compared the group who did not receive a trial of topical prednisolone. [ Time Frame: Monthly for 6 months ]

Secondary Outcome Measures:
  • Visual Acuity [ Time Frame: Monthly for 6 months ]
  • Incidence of other complications (cataract, retinal detachment, endophthalmitis) [ Time Frame: Monthly for 6 months ]

Estimated Enrollment: 70
Study Start Date: September 2008
Estimated Study Completion Date: July 2010
Estimated Primary Completion Date: June 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1
Patients receive Prednisolone 1% 1gtt qid x 4 weeks. If the intraocular pressure (IOP) after the 4 weeks is > or equal to 21 mmHg, then IVTA will be withheld. If the IOP < 21mmHg, then patients will receive an injection of IVTA.
Drug: Prednisolone 1% topical eye drops
Prednisolone 1% 1gtt qid to the eye requiring IVTA
No Intervention: 2
Patients will receive an injection of IVTA (no trial of Prednisolone gtts is given).
