Summary:
The purpose of the study is to evaluate major accommodation disorders in patients with ametropy. Material and Methods. Analysis of the accommodation and hydrodynamics eye state was carried out on 235 people (235 eyes) with myopia (1 group) and 52 people (52 eyes) with hyperopia. The age of patients ranged from 18 to 35 years. Results. Accommodation disorders were observed in 82% of myopia cases; they were expressed through weakness of accommodation (49.2%), habitual excess tension of accommodation (HETA) (18.6%), and combined disorders (14.2%). Accommodation disorders were observed in 86.5% of hyperopia cases, which were expressed through accommodation weakness (51.9%), combined disorders (23.1 %), and HETA(11.5%). At myopia, ophthalmic hypertension was observed in 16.4% of cases with HETA and combined accommodation disorders. Ophthalmic hypertension was detected in 5.4% of hyperopia cases against the background of accommodation weakness. Conclusion. HETA and weakness of accommodation are more often observed with an increase in myopia degree, the rigidity values of the corneoscleral membrane and corneal hysteresis decrease. Weakness of accommodation is more often observed with an increase in the hyperopia degree, the rigidity values of the corneoscleral membrane and corneal hysteresis increase.
