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 ...

OBJECTIVE To assess the usefulness of corneal esthesiometry for screening diabetic retinopathy. METHODS A cross-sectional study was carried out comprising 575 patients attending a diabetic retinopathy-screening program in the city of São Paulo. Corneal esthesiometry was assessed with the Cochet-Bonnet esthesiometer. The presence of diabetic retinopathy was detected with indirect fundoscopy. T...

We apply some recent developments of Baldoni-Beck-CochetVergne [BBCV05] on vector partition function, to Kostant’s and Steinberg’s formulae, for classical Lie algebras Ar, Br , Cr , Dr . We therefore get efficient Maple programs that compute for these Lie algebras: the multiplicity of a weight in an irreducible finite-dimensional representation; the decomposition coefficients of the tensor prod...

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 ...

Infectious bovine keratoconjunctivitis (IBK) is a common ocular disease in cattle, associated with a 6.8 to 13.6 kg decrease in weaning weight. Antibiotic therapy is available but it is unclear if pain mitigation as an adjunct therapy would reduce the weight loss associated with IBK. Before assessing the impact of pain mitigation therapies, it is first necessary to validate approaches to qualif...

To evaluate corneal sensitivity by using the Cochet-Bonnet® esthesiometer in normal canine eyes at different time points following instillation of three different topical non-steroidal anti-inflammatory drugs (flurbiprofen sodium 0.03%, diclofenac sodium 0.1% and ketorolac tromethamine 0.5%) and benzalkonium chloride 0.01%. Six healthy mixed breed dogs from the same litter were used in two diff...

PURPOSE To evaluate the safety of bromfenac sodium eye drops from the standpoint of corneal sensitivity and tear secretion in healthy controls following instillation for 1 month. METHODS A prospective single-blind parallel clinical study was conducted in 20 eyes of ten healthy volunteers with no history of ocular or systemic allergic disease, dry eye, contact lens wear, or ocular surgery. Par...
