Abstract:Objective To investigate the effects of visual perception training combined with 0.05% Cyclosporine A on the ocular surface and tear film of patients with moderate dry eye syndrome.Methods A total of 118 patients with moderate dry eye syndrome treated at Beijing Chaoyang Hospital, Capital Medical University from February 2021 to February 2023 were selected and randomly divided into a control group and an observation group, with 59 cases in each group. The control group was treated with 0.05% Cyclosporine A, and the observation group was treated with visual perception training combined with 0.05% Cyclosporine A. The dry eye symptom score, Ocular Surface Disease Index (OSDI), Depression Anxiety Stress Scale-21 (DASS-21), corneal fluorescein staining (FL) score, tear meniscus height, Optical Quality Analysis System Ⅱ (OQAS-Ⅱ), tear film break-up time (BUT), and tear secretion test (SⅠt) were compared between the two groups.Results The repeated measures analysis of variance showed that there was a significant difference in the dry eye symptom score at different time points (F = 12.133, P = 0.000). The dry eye symptom score in the observation group was lower than that in the control group, and the difference was statistically significant (F = 316.129, P = 0.000). There was a significant difference in the change trend of dry eye symptom scores between the observation group and the control group (F = 10.158, P = 0.000). The difference in OSDI scores and DASS-21 scores before and after treatment was higher in the observation group than in the control group (P < 0.05). The difference in FL and tear meniscus height before and after treatment was higher in the observation group than in the control group (P < 0.05). The difference in MTF cutoff frequency, Strehl ratio, and TF-OSI before and after treatment was higher in the observation group than in the control group (P < 0.05). The difference in BUT and SⅠt before and after treatment was higher in the observation group than in the control group (P < 0.05).Conclusion Visual perception training combined with 0.05% Cyclosporine A has significant efficacy in the treatment of patients with moderate dry eye syndrome, can effectively improve dry eye symptoms, ocular surface health, and visual quality, and is an effective and safe treatment method.
