Abstract
Purpose :
To describe the outcome of preoperative use of a dexamethasone intravitreal sustained-release implant (0.7 mg) in patients with recurrent non infectious uveitis undergoing cataract surgery.
Methods :
Retrospective cohort study. Data recorded from preoperative and post operative visits (1-week, 1-month, 6-month) included : type of uveitis, best corrected visual acuity (BCVA), intraocular pressure, clinical signs of intraocular inflammation, flare values measured by laser flare photometry and central macular thickness (CMT) evaluated by SD-OCT.
Results :
5 eyes of 5 patients with chronic recurrent non infectious uveitis were included. Ten days before cataract surgery, the dexamethasone implant was inserted into the vitreous. Preoperative mean BCVA was logMAR=0.9 improving to logMAR=0 one month after surgery, with a mean gain of 9 lines. The mean preoperative flare value was 13.6 ph/ms. One week and one month postoperatively, the mean flare values were 18.6 ph/ms and 15.7 ph/ms, respectively. Mean CMT as well as IOP remained stable 1 week, 1 month and 6 months postoperatively. No signs of flare-up nor adverse events were noted during the follow-up period.
Conclusions :
Sustained-release dexamethasone (0.7 mg) intravitreal implant may be an effective treatment option for controlling intraocular inflammation after cataract surgery in patients with non infectious chronic recurrent uveitis. These preliminary data in a limited number of patients would warrant a more extensive prospective study comparing the efficacy of dexamethasone intravitreal implant to an alternative treatment regimen, in uveitic patients undergoing cataract surgery.
