LETTERS TO THE EDITOR Long term eVect of repeated hyperbaric oxygen therapy on visual acuity in inflammatory cystoid macular oedema

EDITOR,—Cystoid macular oedema is a well known complication of chronic uveitis and is the major cause of visual disability accounting for 29% of blindness and 41% of visual impairment in this group. ±Therapy consists of control of inflammation with both topical and systemic agents. Symptomatic treatment with acetazolamide orally and grid laser photocoagulation have been shown to reduce cystoid macular oedema as well as vitrectomy. 3 Treatment of cystoid macular oedema has been reported with good results by hyperbaric oxygen, but only limited follow up was presented.
