Excerpt from Annals of Ophthalmology and Otology, 1895, Vol. 4: A Quarterly Journal of Practical Ophthalmology, Otology, Neurology, Rhinology and Laryngology
Where improvement is found from the use of electricity, does this improvement come from a real electmlysis of the opaque tissue, or from the direct irritation of the cornea caused by the stimulus Of the current directly applied? I am inclined to think the last explanation the true one. I am quite sure there is some electrolytic action, but do not think it has any action in clearing the tissue. The electrolysis is noticeable on surface of clear cornea if the current is too strong. Or if the electrode is allowed to remain too long in one spot. There is then a distinct break in superficial corneal layer. The vision in case III was decidedly worse after using electricity. This might be explained by elec trolytic action of current on superficial layers of cornea which, when it was reformed, might be somewhat hazy. The treatment bv this method seems to be adapted to all varieties of corneal opacity, though it is not equally successful in its results with all. Any more than any other one form of treatment. The method by pressure inunction would seem best adapted to opacities produced by in¿ammatory deposit, interstitial and superficial keratitis. There is no one method of treatment that is applicable to all cases. The best results in the majority of cases are obtained from the judicious varying of methods. The cornea, in time, it would seem, becomes tolerant to different irritants. In most recent cases it is best to commence with the milder forms of treatment. As the pressure inunctions then yellow oxid of mercury, or combining the pressure inunctions with the oxid first, and then electricity.
