The abnormal intraocular pressures noted in eyes with retinal detachment have been the subject of both study and conjecture for almost a century.1,2 Despite the incalculable time and effort already devoted to the subject, the relationship between retinal detachment and intraocular fluid dynamics has not been clarified. The clinical finding of hypotony in an eye with a recently detached retina is generally regarded as characteristic, but little attention has been paid to the degree of hypotony and its possible significance. Some authors have observed that the degree of hypotony is roughly proportional to the area of retina detached.3-6 The incidence of hypotony has been reported to increase with the duration of the detachment.3,7 On the other hand, eyes with retinas detached for several months have been found more likely to develop glaucoma after successful reattachment.8 It has even been suggested by Smith that patients with
