"Relative Position of Rest of the Eyes and the Prolonged Occlusion Test"

To the Editor: —In the review of my monograph on "The Relative Position of Rest of the Eyes and the Prolonged Occlusion Test" (The Journal, July 26), your reviewer states that the "prolonged occlusion test" is used to relax spasm of the extrinsic ocular musclesexactlyas atropin relaxes a spasm of the ciliary muscle. (The italics are mine throughout.) No such claim is made in the book itself. On page 2, while the effect of the "prolonged occlusion test" is compared with that of a cycloplegic, thedifferencebetween them is specifically stated. Again, he states that no matter what the patient's muscle balance, refraction, or age, "if asthenopic symptoms were present, a patch was placed over one eye," etc., from which any ordinary reader would infer that all patients presenting symptoms of asthenopia were subjected to the test. This is contrary to what is stated in the book.
