Measurement of corneal temperature.

Measuring the surface temperature of the cornea by contact thermometry has the disadvantages that anaesthesia and sterility are necessary and that temperature is measured at a point. A method of measuring corneal temperature using a bolometer that does not have these disadvantages is described, together with the results obtained. In addition the theoretical and practical considerations in its use are discussed. A value for the emissivity of the corneal surface of between 0·97 and 1 is derived.
