difluprednate and Endophthalmitis

Uveitis is the third leading cause of preventable blindness in the U.S. Topical administration of corticosteroids remains the mainstay in the management of acute autoimmune anterior uveitis. Difluprednate 0.05% ophthalmic emulsion is a potent new topical corticosteroid that exhibits enhanced penetration, better bioavailability, rapid local metabolism and strong efficacy, with a low incidence of adverse effects. In June 2008, difluprednate ophthalmic emulsion 0.05% gained FDA approval in the U.S. for the treatment of postoperative ocular inflammation and pain. Recently, a multicenter, randomized clinical trial showed difluprednate to be noninferior to prednisolone acetate 1% dosed twice as often, the current standard of care for the acute management of endogenous uveitis in the U.S. Furthermore, difluprednate proved to have a comparable safety profile. Here, we review difluprednate pharmacokinetics, ocular indications, animal studies, as well as the results of the clinical trials conducted to date in the U.S.

Implantable collamer lenses (ICL) have gained popularity for correction of myopia where kerato-refractive procedures are not indicated as in cases of high myopic refractive errors. Toxic anterior segment syndrome (TASS) is a very uncommonly reported postoperative complication following ICL implantation. A young patient developed severe corneal oedema and anterior segment inflammation on the first day after ICL implantation. Analysing retrospectively, possible idiosyncratic response to intracameral pilocarpine was considered as a cause for TASS. Prompt and intensive therapy with oral and topical potent steroids was visually rewarding. TASS, though a sterile inflammation can have catastrophic sequelae such as corneal decompensation and secondary glaucoma. Hence, timely identification and management is important.

Cataract is any opacification in lens or its capsule, which accounts for about 50% of treatable blindness worldwide. The prevalence of cataract in India is about 62.6%. The incidence of post operative endophthalmitis ranges from 0.05% - 0.14% and so the use of post-operative antibiotics and steroids is necessary to control infection and prevent inflammation. Fixed drug combinations not only cut the cost but also the dosage and improve the compliance of patients in the immediate post operative period. In this regard, the present study was conducted with the aim of studying the efficacy of using fixed drug combination (Difluprednate and Moxifloxacin) in reducing ocular inflammation and pain in post-operative patients undergoing cataract surgery.. Study design: Prospective interventional study, in which 749 eyes underwent SICS with IOL. All of them were treated with Difluprednate and Moxifloxacin, combination eye drops postoperatively 4 times a day, and reviewed on day 1, 5 and once in two weeks up to 6 weeks.. Out of 749 eyes, 730 were normal, 10 eyes had minimal raise in IOP in the range of 21 mmHg-31mmHg (considering 21mmHg as baseline) which decreased without any intervention within 3 weeks and only 9 eyes had raise in IOP of more than 31mmHg, which did not decrease in spite of discontinuing the drops and needed anti-glaucoma treatment.. Our study clearly shows that fixed drug combination of antibiotic and steroid does not cause raised IOP in about 97% of cases of SICS in the post-operative period and also improves the compliance of the patients.
