Age-related modifications of corneal sensitivity.

Purpose: To evaluate central and peripheral corneal sensitivity (CS) in relation to age.

Methods: Five hundred eyes of 320 healthy subjects (185 males and 135 females) were examined. The age of participants ranged from 20 to 90 years.

Postural modifications of the oscillatory potentials of the electroretinogram in primary open-angle glaucoma.

The postural variations in the retinal microcirculation in glaucomatous patients were studied by evaluation of the oscillatory potentials (OPs) of the ERG. The OPs in scotopic adaptation were examined in subjects with primary open-angle glaucoma and in an age- and sex-matched normal control group in different body positions (seated, supine, anti-Trendelenburg, Trendelenburg). In the seated position, the difference of mean OP amplitude between the control group and the glaucomatous patients was highly significant (p < 0.
