Study summary

The Investigators will compare, in a randomized, prospective, masked and controlled fashion the effect of a non-steroidal 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.

Read the 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.
