Eighty-two tonographic traces in the 68 eyes of 37 normal persons and 25 tonographic traces in the 23 eyes of 17 clinically diagnosed glaucomatous patients were carried out successfully using hand holding Schiotz tonometer. A nd the usefulness of this method was discussed according to the following results obtained.
Average C value was 0. 271 cu. mm/min. /mm Hg. (range 0. 12-0-49), the average F value was 3.255 cu. mm/min. (range 1. 29 ,-6.77) and the average original intraocular pressure (Po) was 16.691 mm Hg. in the normal eyes. Only 3 eyes showed less than border line (C=0.15) in which 2 cases were 100 or more in the ratio of Po and C.
In the glaucomatous eyes including one case of considerably improved after having operation, the average C value was 0.096 (range 0.02-0.16-0.23), the average Po was 37.12. Four eyes of these showed between 0. 12 and 0. 15, and only 3 eyes showed over 0. 15 in C value.
An average 1.95mm Hg. of intraocular pressure was noted to be decreased after tonographic traces in the 36 fellow eyes in the normal persons.
Twenty-six of 36(72.2%) fellow eyes showed decreased F value and 10 eyes of them (27.7%) showed increased F value in the normal persons. On the other hand, only one of six fellow eyes of the glaucomatous patients showed increased F value.
All of the glaucomatous eyes showed 100 or more in the ratio of Po and C. (Po/C) while 7 of 82 normal eyes showed 100 or more in the same ratio.
