Simple over-distension of the cornea, by an unwonted accumulationof the aqueous humor, produces both dimness and prominence. If tIn-state be the concomitant of an existing inflammatory process pervadingthe eye, as corneitis, by subjugation of this the cornea will sometimesbe restored.

Repeated evacuation of the aqueous humor, by means of aneedle, is often of service. Affections of the Sclerotic Coat. Sclerotitis. This may occur as part of a general inflammatory process, howeverexcited. Not unfrequently, it exists per se, and then almost uniformlyis of rheumatic origin; exposure to cold, probably, having proved theexciting cause. It is most frequent in the adult, and about the middleperiod of life, and is often limited to one eye. Pain is complained of,of a dull, aching kind; increased by pressure, and by movement of theglobe; partly resident in the eye, but mainly in the forehead and tem-ple ; and marked exacerbation occurs at night.
