[Pupillary function in children with initial myopia].
The paper describes results after a study of pupillary characteristics in 60 children with emmetropia and hypermetropia of low degrees (120 eyes) and in 75 children with initial myopia (150 eyes), using the methods of photopupillography and determination of IPCT (induced pupillary cycle time). On the basis of analysis of the results obtained a hypothesis is suggested that progressive myopia is connected with exhaustion of tonic accommodation. The study of possible usage of IPCT allowed to recommend this parameter to be used as an auxiliary (in calculating the rate of pupillary reaction) or an independent criterium for assessment of the functional state of the pupil as well as a method of medical examination. A simple and a sufficiently informative method for investigation of pupillary reaction is suggested, which is based on the usage a slit lamp together with a photorecording device.
