Retinal dialysis.
Whether idiopathic or the result of ocular trauma, retinal dialysis is one of the least understood causes of retinal detachment. Dialyses are a common cause of retinal detachment and are the leading cause of traumatic retinal detachment in children and young adults. A dialysis is a disinsertion of the retina found at the ora serrata, generally involving less than 3 clock hours. Because a patient may be asymptomatic, a dialysis may be missed during ophthalmoscopic examination of the ocular fundus unless scleral indentation is used. Anatomical reattachment of detachments from retinal dialysis is highly successful for dialyses of both traumatic and idiopathic origin, with good visual results obtained postoperatively.
