Introduction: The Retro-IDEAL (ILUVIEN Implant for chronic DiabEtic MAcuLar edema) study is a retrospective study designed to assess real-world outcomes achieved with the ILUVIEN® (0.19 mg fluocinolone acetonide (FAc)) in patients with chronic diabetic macular edema (DME) in clinical practices in Germany. Methods: This study was conducted across 16 sites in Germany and involved 81 eyes (63 patients) with persistent or recurrent DME and a prior suboptimal response to a first-line intravitreal therapy (primarily anti-VEGF intravitreal therapies). Results: Patients were followed-up for 30.8 ± 11.3 months (mean ± standard deviation) and had a mean age of 68.0 ± 10.4 years. Best-recorded visual acuity (BRVA) improved by +5.5 letters at month 9 (P ⩽ 0.005, n=56; from a baseline of 49 letters) and this was maintained through to month 30 (P ⩽ 0.05, n = 42). There was a concurrent improvement in central macular thickness with a reduction from 502 µm at baseline to 338 µm at year 1 (P ⩽ 0.0001, n = 43). This effect was sustained to year 3 (i.e. 318 µm; P ⩽ 0.0001, n = 29). Mean intraocular pressure (IOP) remained constant between baseline and year 3 with a peak change of 1.9 mm Hg occurring at year 1. Elevated IOP was observed in a similar

Purpose: To review the occurrence of macular retinal folds following retinal detachment surgery. Method: Review of the literature. Results: Macular folds have been reported in up to 3% of cases postoperatively. Risk factors are tamponading gas bubble, large exoplants, detachments with bullous configuration or running through the fovea, and incomplete drainage of subretinal fluid. Preventive measures include correct posturing and avoidance of modifiable risk factors. The natural history is variable. Complete resolution as well as persisting folds with permanent structural damage have been reported. Treatment indications and techniques remain controversial. Very few successful reports of surgical correction have been published to date. Conclusions: Macular folds are a serious but underreported complication of retinal detachment surgery that can be avoided in the majority of cases. Macular folds can be prevented by correct posture and avoiding large exoplants, large tamponade bubbles and incomplete drainage of subretinal fluid.

Intravitreal bevacizumab (Avastin) resulted in a reduction of leakage, intra- and subretinal fluid. An increase in visual acuity was seen already 4 weeks after first injection. However, a complete occlusion of feeder vessels could not be achieved within this 3-month period. Randomized clinical trials would be required to evaluate dose and frequency of injections and possible beneficial effects of combination therapies, as well as the long-term results.

Treatment intensity was not sufficient to maintain the initial improvement in visual acuity by ranibizumab treatment. Real-life results for visual acuity and injection frequency in the German cohort were worse at that time than in other countries. Regular follow-up visits as well as timely retreatment in the presence of signs of disease activity are required to achieve optimal results in wAMD when applying a pro re nata-based strategy.
