AIMS To evaluate the effect of topical autologous plasma on nerve morphology in patients with neurotrophic keratopathy (NK) using the confocal microscope. METHODS Eleven eyes of six patients with neurotrophic keratopathy were evaluated for this study. Corneal fluorescein staining was done, and corneal sensitivity measurements were done with the Cochet-Bonnet and modified Belmonte gas aesthesiom...

PURPOSE To examine the potential harmful effects on corneal structure, innervation, and sensitivity of a spray containing the neurotoxin capsaicin (oleoresin capsicum, OC). METHODS Ten police officers who volunteered for the study were exposed to OC. Clinical signs were assessed. Corneal sensitivity was measured using a Cochet-Bonnet or a noncontact esthesiometer that provides separate measur...

Diabetes mellitus (DM) is a complex and chronic metabolic disorder leading to many complications. One of the most common complications of DM is diabetic neuropathy. There are many studies exploring corneal sensitivity as a potential marker of diabetic neuropathy. This review aims to explore association between corneal sensitivity and diabetic neuropathy. In diabetic neuropathy, corneal sensitiv...

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...

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 ...

Using the Cochet-Bonnet esthesiometer, we evaluated the corneal sensation of 11 patients with unilateral Adie's tonic pupil. We eliminated six other patients with bilateral Adie's pupil or disease that lowered corneal sensation. An observed unfamiliar with each patient's condition tested 12 clock hour positions in the midperiphery in both eyes of all patients. We studied 30 normal subjects (60 ...
