Влияние различных типов плавающих помутнений стекловидного тела на субъективное качество зрения

Abstract

Purpose. To compare subjective visual quality on patients with different types of vitreous floaters. Material and methods. The study included 68 patients (68 eyes). Three groups were formed: I – Weiss Ring – 24 eyes, II – Сloud opacities – 22 eyes, III – Solid conglomerates – 22 eyes. To evaluate the visual quality all subjects completed non-standartised questionnaire. Laser treatment was performed with the “Ultra Q Reflex” using pulse energy 3–7 mJ. Follow-up: at the baseline and, 1 months after treatment. Results. There was a statistically significant difference observed in I group in questions of floaters intensity and occurrence frequency compared to the II and III groups. In the II group there was a statistically significant difference in questions of spots size and number compare to the other floaters. In the III group there was a statistically significant difference of overall quality of life questions compare to the other patients. Comparative analysis of survey outcomes in groups I and II revealed a significant increase of subjective perceptions (p < 0,05) and a positive trend in groups III at 1 month follow-up after laser surgery. Conclusions. Patients with Weiss rings and cloud-like floaters have great psychological discomfort, with the little impact on the visual functions of patients. On the contrary, solid conglomerates, due to their structure, have a significant impact on the subjective quality of vision and impede daily activities. The initial type of floaters determines the tactics of management, as well as the results of laser treatment. Keywords: YAG laser vitreolysis, vitreous floaters, questionnaire.
