Excerpt from Oculo-Refractive Cyclopedia and Dictionary Commonest among these accommodative anomalies is a periodic (clonic) or a permanent of the ciliary muscle, which frequently occurs in hyperopia, and which results in a certain amount of locked accommodation that is not easy to demonstrate by any of the methods described above. Subjectively, such a patient's far point would register inside of its mathematical range, because he is not able to attain complete ciliary relaxation. It may register at infinity, in which case he will appear, so far as his far point is concerned. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
