It includes many types, which have varied pathology, histology and clinical manifestations. Recently, the examination techniques of ophthalmology and gene sequencing advance greatly, which do benefit to our understanding of these diseases. However, many aspects remain still unknown. And due to the poor knowledge of these diseases, the results of the treatments are not satisfactory. The purpose of this review was to summarize the clinical, histological and genetic characteristics of different types of corneal dystrophies.展开更多

Sociodemographic information was also collected. Data were analyzed via the Spearman rank correlation test and stepwise regression.RESULTS: The personality and coping variables are predictive and jointly account for a significant amount (45.3%-54.2%) of variance across the two subscales of anxiety measures. Notably, neuroticism seems to be most closely related to anxiety disturbances in glaucoma patients. The level of resignation is positively linked to anxiety scores.CONCLUSION: Some personality factors and coping modes help to predict the process of anxiety disorders in primary glaucoma patients. Recognizing the predictive role of these variables in the patients may further enrich clinical research in glaucoma and help to design more effective interventions involving both ophthalmology and psychiatry.展开更多
