June 17, 1932.
To the Editor.—In regard to Dr. Linn Emerson's letter in the June Archives (7:954, 1932), I wish to state that I have used for years one-fifith grain (13 mg.) of homatropine dissolved in 4 drops of boiled hot water; 1 drop of this is instilled in each eye, followed in ten or fifteen minutes by the remaining drop in each eye. In half an hour after the last drop, refraction and retinoscopy are very satisfactory. I have repeatedly added atropine afterward to get further cycloplegia, but without much result. There is no pain following the drops.
The use of homatropine as described, followed by a drop of physostigmine solution, allows the patient to become practically normal in six hours. I should like others to try it. I have never seen any ill result.
