ERM surgery resulted in similar anatomical and functional outcomes in both groups. Longer axial length does not seem to affect visual improvement and the complication rate.
Gaucher's disease is an autosomal recessive inherited disease characterized by oraganomegaly, cytopenia and bone destruction. Clotting disorders and platelet dysfunctions are described. We report the case of a 22-year-old man who presented subacute groin pain due to spontaneous iliopsoas hematoma. Laboratory investigations found moderate thrombocytopenia, normal coagulation factor activities and unspecific platelet function test disturbances. His spleen was moderately enlarged and no significant bone lesions were found. Iliopsoas hematoma is a rare complication in Gaucher's disease and should be included in the differential diagnosis of pain localized to the groin-hip area, which could rather evoke hip osteonecrosis in this context.

SUMMARYOptic nerve disease has been reported in patients with renal failure. A toxic aetiology has been postulated. The incidence of this complication of renal failure has not been determined. We observed 60 patients with renal fail ure on dialysis for 24 months to determine the incidence of optic neuropathy. Four patients developed typical acute ischaemic optic neuropathy. Their case notes were reviewed in order to determine the pathogenesis. Each patient had long-standing renal failure and its sequelae of anaemia and hypertension. The immediate causes of ischaemia were hypotension in 1, severe anaemia in 1, and generalised atherosclerosis in 2 patients.Optic neuropathy is a well-known complication of renal failure/dialysis. A neurotoxic type of optic neuropathy in uraemic patients with a serum urea nitrogen level of more than 35.7 mmol/I was reported by Knox and associates, 1 who implicated hypertension and anaemia as well as a raised serum urea nitrogen. Medical management with haemodialysis was followed by improvement of vision in 4 of their patients. In 1 patient resumption of cortico steroid therapy was followed by improvement in vision, but the patient whose vision improved the most rapidly was managed by prompt use of both dialysis and oral corticosteroids.Hamad and associates described a similar type of optic neuropathy 2 in patients maintained on dialysis. In 1 case desferrioxamine toxicity was suspected. Other risk factors identified were again hypertension, anaemia and a raised serum urea nitrogen. Their third patient had profound loss of vision, and the likelihood of an atypical non-arteritic acute ischaemic optic neuropathy (AI ON) in a young patient in that particular clinical setting was noted.In contrast, all 4 of our patients had typical non-arteritic acute ischaemic optic neuropathy.
