Nontraumatic retinal dialysis (Fig. 12.2) accounts for approximately 10 % of all juvenile retinal detachment [17,43]. The male-to-female ratio is 3:2 [43] and the majority of patients are hypermetropic or emmetropic [17,33,36]. In 97% of cases, the dialysis affects the inferotemporal quadrant but multiple dialyses occur in one-third and 37% may be bilateral [43]. Detachments associated with dialyses progress slowly, have a low incidence of PVR and characteristically present either as an incidental finding or when the macula becomes detached. They can be managed routinely with buckling techniques

and the use of a small (typically 3-mm) circumferential sponge reduces the likelihood of postoperative motility problems. Although the anatomical success rate of surgery is high, visual recovery may remain poor if there has been chronic macular involvement. Examination of the fellow eye under anaesthesia is also important, as retinal dialysis may be bilateral and oral abnormalities, in the form of a "frill" or flat dialysis, are found in the fellow eye in up to 30 % of cases.
