Preliminary analysis of community screening results of non-mydriatic fundus photography among retired university staff
Objective This study was aimed at exploring the application value of non-mydriatic fundus photogra-phy technology in the screening of fundus diseases among college faculty,and to analyze the common types of fundus diseases among retired university staff.Methods This cross-sectional study involved vision and slit lamp examinations of 1 056 retired university staff members,and non-mydriatic fundus photographic examination.Preliminary diagnosis was based on acquired images.The initial diagnosis of macular disease was confirmed with OCT.Patients with a preliminary diagnosis of diabetic retinopathy underwent fundus fluorescein angiography to confirm the diagnosis.Patients with an elevated cup-to-disk ratio and suspected glaucoma were referred to a higher-level hospital to rule out early glaucoma.The degree of retinal arteriosclerosis in patients with retinal arteriosclerosis was graded,and the influence of blood pressure and age on the retinal arteriosclerosis grade was analyzed.Results Among the 1 056 patients screened,933 fundus images were available for analysis.We identified 367(39.33％)cases of retinal arteriosclerosis;42(4.50％)cases of increased cup-to-disk ratio;9(0.96％)cases of macular epithelium;5(0.54％)cases of age-related macular degeneration;4(0.43％)cases of macular hole;3(0.32％)cases of diabetic retinopathy;1(0.11％)case of old retinal vein occlusion;and 1(0.11％)case of vitreous stellate degeneration.Higher grade of retinal arteriosclerosis and older age were associated with higher systolic blood pressure and diastolic blood pressure,and the differences were statistically significant(F=543.037,P＜0.001;F=245.146,P＜0.001;F=47.176,P＜0.001).Conclusions Retinal arteriosclerosis is a common fundus disease among retired college employees.Blood pressure and age affect the occurrence and develop-ment of retinal arteriosclerosis.Non-mydriatic fundus pho-tography can be routinely used in fundus screening among college faculty.
