ObjectiveThe aim of the Iluvien Clinical Evidence study in the UK (ICE-UK) was to assess the real-world effectiveness of fluocinolone acetonide (FAc) 190 µg intravitreal implant for the treatment of clinically significant chronic diabetic macular edema (DME) in routine clinical practice.MethodsThis retrospective study collected data from patient medical records in 13 ophthalmology centers for people with DME prescribed FAc intravitreal implant between April 1, 2013 and April 15, 2015. Visual acuity (VA) and intraocular pressure (IOP) measurements were collected for 12 months prior to and after implant.ResultsTwo hundred and eight people, contributing 233 eyes, treated with FAc implant were included. Mean age was 68.1 years and 62% were male. In the 12 months prior to FAc implant, VA declined. Median (interquartile range, IQR) VA was 0.66 (0.48-1.00) LogMAR units (equivalent to 52.0 ETDRS letters) at implant, improving to 0.60 (0.38-0.90) LogMAR units (55.0 letters) at 12 months post-implant (p < 0.001). In total, 44%, 30%, and 18% of people achieved an improvement in ETDRS score of ≥5, ≥10, and ≥15 letters, respectively, over the same period. A small but significant (p < .001) increase in median IOP was observed (median = 15.0, IQR = 13.0-18.0 mmHg at implant to 18.0, 15.0-21.0 mmHg at 12 months). In the 12 months following implant, additional IOP-lowering therapy was prescribed in 15% of subjects previously not requiring such therapy.ConclusionFollowing FAc implant, an overall significant improvement in VA was observed over a period of 12 months, accompanied by a significant but small increase in IOP.
