Difficulties attending the functions of accommodating and of adjusting the eyes in the act of vision, or irritations arising from the nerves involved in these processes, are among the most prolific sources of nervous disturbances, and more frequently than other conditions constitute a neuropathic tendency. — Stevens
As an ophthalmic surgeon with a flourishing practice, Stevens discovered neurological and psychological benefits which were ancillary to his surgical treatments for eye disorders. This work is his documentation of these neurological cures drawn from 2690 cases of which the preponderance involved asthenopia, including 1280 cases of cephalagia. However, inspired by the work of Donders, Stevens looks for clinical evidence of an organic relationship between eye disorders and more serious neurological problems such as epilepsy and even mental disease. Of the latter he presents three cases, two represented photographically (plates 5 and 6), and one interesting case of a young woman probably suffering a conversion disorder and imagining herself to be a wheelbarrow being trundled about.
Originally published in French as a thesis without the photographic plates or the explanatory text to the plates. In the preface, Stevens writes that the original negatives were destroyed in a fire and consequently reproductions were made from "very indifferent prints."
