Condition(s) targeted: Open Angle Glaucoma

Intervention: Acular LS (Drug); Pred Forte (Drug); Refresh Tears (Other)

Phase: N/A

Status: Completed

Sponsored by: University of Colorado, Denver

We will compare, in a randomized, prospective, masked and controlled fashion the effect of a nonsteroidal anti-inflammatory agent (Acular LS), a corticosteroid (Pred Forte) and a placebo (Refresh Tears) on patient discomfort, degree of intraocular pressure (IOP) lowering and degree of ocular inflammation following selective laser trabeculoplasty treatment for open angle glaucoma.

Clinical Details

Official title: A Randomized Prospective Double Masked Controlled Trial Comparing Ketorolac Tromethamine 0.4% and Prednisolone Acetate 1% in Reducing Post-selective Laser Trabeculoplasty Anterior Chamber Flare and Cells.

Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Single Blind (Investigator), Primary Purpose: Treatment

Primary outcome: Patient Discomfort, Degree of Intraocular Pressure Lowering, and Degree of Ocular Inflammation

Detailed description: Currently, many ophthalmologists use anti-inflammatory agents like corticosteroids and nonsteroidal anti-inflammatory agents (NSAIDs) as a preventative measure to control the post-selective laser trabeculoplasty (SLT) anterior chamber inflammation. Both classes of compounds reduce inflammation through the inhibition of the cyclooxygenase pathway, whereas the corticosteroid class also inhibits the lipoxygenase pathway of the arachidonic acid cascade. Although effective, topical corticosteroids are associated with increase in intraocular pressure (IOP), posterior subcapsular cataract formation, and reduced response to infection. These adverse side effects have not been reported to occur with topical NSAIDs, which are effective in controlling the pain after SLT along with the prevention and suppression of the ocular inflammation. There are ophthalmologists who forgo using the anti-inflammatory agents post SLT and prescribe Refresh Tears to their patients to comfort the treated eye. The significance of the study lies in assessing the efficacy of Acular LS, compared to Pred Forte and to Refresh Tears in reducing discomfort, inflammation and maximizing IOP lowering following SLT procedure for open angle glaucoma with the hope of resolving the dispute over the effective post-operative care in SLT patients.
