Pilot Study of the Effect of Topical Bromfenac Ophthalmic Solution 0.09%in Patients With Acute Post-operative Cystoid Macular Edema.
This research is being done to look at the effects of Bromfenac, also called Xibrom for the treatment of swelling in the retina (the light sensitive tissue in the back of the eye) called "macular edema" that occurs after cataract surgery. Swelling in the retina can lead to blurry vision.
The most commonly used treatment is eyedrops that decrease inflammation and may help stop some of the swelling. The investigators want to see if the drug Bromfenac(Xibrom) can decrease the swelling in the retina after cataract surgery and improve vision in these patients.

Over 2.5 million cataract surgeries are performed yearly in the United States. Despite advances in cataract surgery, cystoid macular edema (CME) is the most common cause of loss of vision after cataract surgery, occurring in approximately 0.3% to 3% of all uncomplicated surgeries. If the surgery is complicated, CME can occur in up to 20% of these patients. In CME, fluid accumulates in cystic spaces within the outer plexiform layer of the retina, resulting in decreased vision.
Ocular nonsteroidal anti-inflammatory drugs (NSAIDs) have been widely used in the treatment of CME. NSAIDs decrease inflammation and are hypothesized to decrease the production of prostaglandins via selective inhibition of the cyclooxygenase pathway, which can result in CME. The standard of care for management of postoperative pseudophakic macular edema to some extent remains unclear. There is currently no FDA-approved therapy for the prophylaxis or treatment of postoperative cystoid macular edema.
Bromfenac (Xibrom)an NSAID and is FDA-approved for ocular use to treat pain and inflammation after ocular surgery. Therefore, these medications might decrease inflammation and be effective in treating CME. The investigators plan to conduct a controlled study to investigate the effect of Bromfenac (Xibrom)in patients who develop CME after cataract surgery. The results of this study may be important in better understanding the pathogenesis and treatment of acute postoperative cystoid macular edema to prevent chronic vision loss.
