Development of the Various Methods of Esthesiometry,ould be as little curved as possible, is attached to the end of a light wood rod of about 8 cm length. The hair lies vertical to the axis of the rod so that it will on one side protrude for 20–30 mm, under certain circumstances even more. Such a rod presents with appropriate application a stimulus o亵渎 发表于 2025-3-30 18:45:14
Comparison Between Static and Dynamic Esthesiometry,any of the previous instruments to raise the stimulus force continuously during corneal contact. This new method avoids any error due to the speed with which the test body advances toward the cornea. The instrument is advanced with a subliminal stimulus and therefore the threshold for touch alone ca万花筒 发表于 2025-3-30 22:33:57
Topography of Corneal Sensitivity,s would allow us to evaluate clinical problems of threshold changes. We therefore measured the corneal sensitivity at thirteen different areas of 20 to 40 year-old subjects. The measurements were taken on four meridians, at the limbus, 1 mm from the limbus, at a point between the center and this are苦笑 发表于 2025-3-31 02:32:14

,Stimulus-Sensation — Relationship in the Cornea,refore we carried out the following series of experiments with the new esthesiometer:.To determine the correlation between stimulus strength and sensation, six different forces (1.5 − 3 − 6 − 12 − 24 − 48 × 10.N) were applied in a random sequence. Points of measurement were the corneal center and thFRONT 发表于 2025-3-31 09:27:14
The Sensitivity of the Conjunctiva,rding to v. Frey and Strughold (1926) only touch and pain sensations can be elicited from the cornea; the conjunctiva has in addition a sensation for cold which we shall, however, not consider in this monograph. Previous authors (v. Frey and Strughold, 1926; Boberg-Ans, 1955; Norn, 1973) agreed that心胸开阔 发表于 2025-3-31 15:14:11

The Lid Reflex as an Indicator of Corneal and Conjunctival Sensitivity,feit would also lead to a reflectory lid closure and if this reflex could not be voluntarily suppressed. A stimulus placed in the corneal center, even if it is slightly suprathreshold, will always elicit a reflectory lid closure. This reflex does not diminish or cease with repetition.
