Traumatic retinal dialyses

To the Editor. —In the AugustArchives(1981;99:1371-1374), Ross concluded after examining 50 patients who underwent retinal dialysis that all retinal dialyses probably result from trauma and that genetic weakness of the retina at the ora serrata is not an important factor. In his analysis of inferotemporal dialyses, the author stated that in 15 of 36 dialyses (34 patients), the history was either forgotten or denied for social reasons. Although the number of dialyses in the remaining retinal quadrants came to 13, only one patient in this category denied a history of trauma. In support of a nonhereditary cause of inferotemporal dialyses, Ross also stated that there was no family history of dialysis in any of these 34 patients, but he does not mention if siblings or other relatives of these patients were examined by indirect ophthalmoscopy and peripheral scleral depression.
