To the Editor.
—In their article, published in the September 1988 issue of the Archives, Atta and Byrne1 state that "hypermetropia is a frequent cause of choroidal folds." They further state that "choroidal folds may be produced by any of the following mechanisms: (1) scleral shortening as in primary hypermetropia; (2) choroidal thickening as in scleritis, trauma, or hypotony; and (3) enlargement of various retrobulbar orbital structures, such as the optic nerve, the extraocular muscles, or Tenon's space."In our study2 published in May 1986, we reported one- to seven-year follow-up of 12 eyes in nine patients diagnosed to have posterior scleritis. A-scan and B-scan ocular echography demonstrated extensive choroidal and scleral thickening with associated edema of Tenon's space and of the optic nerve sheath, and all the involved eyes had choroidal folds present and had acquired hyperopia. Observations presented by Atta and Byrne are very similar to
