Is Corneal Sensitivity Sex Dependent?
PURPOSE To determine whether corneal sensitivity is different between the two genders. METHODS Corneal sensitivity of 130 normal volunteers, including 77 women and 53 men aged 20-35 years, with no history of previous ocular surgery was measured using the Cochet-Bonnet esthesiometer. Measurements were done on five corneal regions: central, nasal, inferior, temporal and superior. The findings w...
متن کاملHedonic sensitivity to low-dose ketamine is modulated by gonadal hormones in a sex-dependent manner.
We recently reported a greater sensitivity of female rats to rapid antidepressant-like effects of ketamine compared to male rats, and that ovarian-derived estradiol (E2) and progesterone (P4) are essential for this response. However, to what extent testosterone may also contribute, and whether duration of response to ketamine is modulated in a sex- and hormone-dependent manner remains unclear. ...
متن کاملAssessment of Corneal Sensitivity.
ACCURATE measurement of corneal sensitivity was first attempted by von Frey (1894), using as a criterion the length and bend of a horse hair through which pressure was applied and increased until the threshold of sensation was reached. The basic principle laid down by von Frey was generally accepted. Modifications were made by using different materials and adjustable plastic thread, which permi...
متن کاملCorneal Sensitivity and Contact Lenses.
IT is a matter of experience that certain persons adjust well to contact lenses while others do not, despite perfect fitting. This adjustment is greatly facilitated if the sensitivity of the cornea is decreased, as it is after cataract extraction. One is therefore tempted to consider corneal sensitivity as a determining factor for the success of a fitting. Previous investigation of the subject ...
متن کاملCorneal sensitivity in myasthenia gravis.
Corneal touch thresholds were measured in 11 people suffering from myasthenia gravis (MG) and in a control group of 20 subjects. The mean threshold in MG was 75.6 mg (SD 52) and in the control group 18.9 mg (SD 7.3); thresholds were thus significantly (p less than 0.01) raised in MG. Although it is not possible to say whether the sensory deficit is due to MG or to the treatment, the results imp...
