– In patients with diabetic macular edema, vitrectomy appears to produce a significant decrease in foveal thickness, according to a report published in the August issue of the American Journal of Ophthalmology. Previous reports have suggested that vitrectomy may be an effective treatment for diffuse macular edema.
However, none of these reports were based on controlled studies, study authors Dr. Tomohiro Otani and Dr. Shoji Kishi point out. To address this, the researchers, from the Gunma University School of Medicine in Maebashi, Japan, assessed the outcomes of seven patients with bilateral diabetic macular edema who underwent vitrectomy in only one eye.
Prior to treatment, the same degree of edema was present in both of the patients’ eyes. The average followup period
was 6.2 months.
