One must cease, therefore, to be surprised at the success of Adams, Phillips, Petrequin, Guerin, and others, who cured asthenopia by dividing some of the ocular muscles. The error into which I con- ceive these surgeons have fallen, is in supposing that all forms of this affection are due to the same cause, and can be cured by a like remedy. In the second section of this chapter, I gave some examples of the form of impaired vision here alluded to, and which appeared to be un- equivocally due to a morbid condition of one of the recti muscles. The two following cases, though they illustrate well this combined defect
