Abrégé

In the solution of the invention at least one an electrical response signal from a retina is acquired in a first temperature, at least one electrical response signal from the retina is acquired in at least a second temperature, the second temperature being different than the first temperature. At least the electrical response signal acquired in the second temperature is transformed with a plurality of different transformation parameter values resulting a plurality of different transformed signals. The different transformed signals of the electrical response signal in the second temperature are compared to the electrical response signal and/or the transformed signals acquired from the retina in the first temperature. The transformed electrical response signal which produces the highest similarity measure with the electrical response signal and/or transformed signal acquired from the retina in the first temperature is selected. The transformation parameter value or parameter values of the selected transformed signal is converted to a temperature, temperature difference estimate and/or temperature dependent indicator between the first temperature and the second temperature.

Abrégé

A method and device for non-invasive monitoring of the temperature of the retina and the retinal pigment epithelium inside the eye, particularly during heating of the bottom of the eye, wherein alternating probing short-duration pulses of light, one at wavelength close to the absorption maximum of the photoreceptor cell type and the other at wavelength in the near-infrared region, are directed at the retinal tissue at appropriate time intervals. Photoreceptor cell electrical signals, photoresponses, are recorded using electroretinography (ERG) and the changes in retinal temperature are determined from changes in photoresponse kinetics and changes in photoreceptor sensitivity to the stimuli. The method is especially applicable at temperatures up to 45° C. for humans and for other animals.
