Resolution of macular oedema in Coats' disease with intravitreal bevacizumab

A 13-year-old boy was referred because of visual deterioration in his right eye. The visual acuity was two metres of counting fingers. Indirect ophthalmoscopy and biomicroscopy revealed exudative macular oedema as well as tumour-like telangiectatic vessels and exudation in temporal periphery. With diagnosis of Coats' disease (stage II) confirmed by fluorescein angiography, three intravitreal injections of bevacizumab were performed at 6-week intervals. One year after the last injection, there was a significant resolution of macular oedema as well as visual acuity improvement to 20/20. This is the first case report in which a distinct improvement in macular oedema was observed with intravitreal bevacizumab in Coats' disease.
