Frequency of anisocoria in patients with astenopia

Abstract

AbstractPurpose Anisocoria ‐ an unequal size of pupils. According to literary data, almost 10 % of the healthy population has a difference in diameter of pupils no more than 1 mm in photopic conditions of illumination and in 20 % of cases – in mezopic. Differential diagnostics of physiological and pathological anisocoria frequently causes certain difficulty and in this question the essential help is rendered by modern diagnostic methods of research, including computer pupillography which allow evaluating objectively pupil sizes and its changes on different stimuli.To reveal if anisocoria in patients with astenopia can be found and what kind of anisocoria it is.Methods 91 patient at the age 7 ‐ 23 y.o. were observed. They had astenopia complaints; some of them had pupil unequal size, no somatic pathology. Pupillography was done by elaborated pupillography devise, blood circulation of the brain was defined by method of computer reoencephalography .Results 13 % (12) of observed patients had anisocoria. During direct, consensual and accommodative reaction asymmetry of pupil’s square have increased on 45,5 %, 51% and 67 % accordingly. Volume of blood supplement in internal carotids had increased values in average on 65 % from age norms. Marked asymmetry was found between right and left a. carotid internal which reached 50 % at 9 patients, and at 3 to 70 % in the given pool.Conclusion Anisocoria was revealed in 13% of patients with astenopia. Patients who had anisocoria, astenopia and accommodative dysfunction had functional disorders of brain blood circulation.
