IntraVitreal Triamcinolone Acetonide: Preventing Raised Eye-Pressure by Tracking Elevations After Topical Steroids (IVTA:PRE-TREAT)
This study is not yet open for participant recruitment.
Verified by Hotel Dieu Hospital, August 2008
Sponsors and Collaborators: Hotel Dieu Hospital
Sunnybrook Health Sciences Centre
Information provided by: Hotel Dieu Hospital
ClinicalTrials.gov Identifier: NCT00744666
  Purpose

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 ] [ Designated as safety issue: Yes ]

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

Estimated Enrollment: 70
Study Start Date: September 2008
Estimated Study Completion Date: July 2009
Estimated Primary Completion Date: June 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
1: Experimental
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
2: No Intervention
Patients will receive an injection of IVTA (no trial of Prednisolone gtts is given).
