CHAPTER XVII. HIGH-FREQUENCY AND X-RAY INTREATMENT OF THE EYE. THE THE HIGH-FEEQUENCY CURRENT IIST OPHTHALMIC PRAC-TICE. High-Frequency.—L. Webster Fox, who- liasmade a profound study of the effect of the high-frequency current in eye diseases, cites the followingillustrative cases, many of which go to prove whatthe current will not accomplish: Fox used a high-frequency coil, with an Oudinresonator and made the application to the lids by avacuum spiral glass tube and directly to the corneaby glass vacuum eye electrodes for two to twenty.

Blepharitis Marginalis.—One hundred caseswere treated, ten minutes daily for two weeks. Thecure was apparently permanent in all. Granular Lids.—Ten cases. After twenty treat-ments to the external surface of the lids in each case,there was no benefit. Ulcers of the Cornea.—Twenty-five cases—allforms from simple to Saemisch. Application wasmade to the lids and cornea. When there was de-structive tissue, the process seemed to be case of Saemisch was cured without other electrode was applied to the cornea, undercocain, in all. Iritis.—Five cases; three specific, two rheu-matic. There was no notable change for the better,but the pain lessened. In one case, ten minutes oftreatment gave instant relie
