METHOD AND DEVICE FOR EFFECTING AESTHESIOMETRIES |
摘要 |
The method comprises: (a) applying to the cornea or conjunctiva of the eye, whose sensitivity is to be determined, a flow of gas which contains CO2 and air in variable concentrations, or an acid isotonic solution; and (b) effecting a qualitative or quantitative aesthesiometry of the local irritation produced by the application of the irritating product, based on the determination of the pain threshold and intensity, through oral answers or the use of a logic scale. The device comprises a CO2 bottle (1); an air bottle (2); a gas mixing device (3); a gas flow indicator (4); a CO2 content indicator (5) (as a percentage); a pressure transducer (6); an oscilloscope (7); a valve (8); a pulse generator (9); a lens universal support (10); the numeral (11) representing the cornea of the individual to be examined. Application for the measurement of the corneal and conjunctival sensitivity of the eye. |
