Abstract
Purpose :
Up to now, there is no report about screening disease types of telemedicine though the method of tele-image reading of ophthalmology in China. The purpose of this study is to investigate disease type in teleophthalmic image reading center of Beijing Tongren Hospital from March to April in 2015.
Methods :
1192 cases were evaluated continuously by an ophthalmic chief physician specialized in glaucoma and ocular fundus disease in Beijing Tongren Hospital image reading center of teleophthalmology from March to April in 2015. The subjects came from 54 hospitals with primary or second grade in China. The demographic data, visual acuity and ocular fundus photographs of subjects were saved on a cloud computing platform with software (Daheng Prust Co., Beijing). Ocular fundus image reading and evaluating was also based on the same cloud computing platform.The disease constituent ratios in different age (less than 50 years old and 50 years old or more) and geographic location (the northern and southern of the Yellow River) were retrospectively compared.
Results :
In all 1192 subjects, ametropia, cataract, hypertensive retinopathy, diabetic retinopathy, macular preretinal membrane, pathological myopia, glaucoma, branch retinal vein occlusion, AMD was in 34.3%, 22.9%, 19.1%, 7.1%, 4.8%, 3.9%, 2.4%, 2.1%,1.8%, respectively. Ametropia, cataract, hypertensive retinopathy, diabetic retinopathy, macular preretinal membrane, glaucoma, branch retinal vein occlusion, AMD in less than 50 years old group (366 cases) and in 50 years old or more group (826 cases) respectively were in 45.9%, 29.1% (P=0.000); 5.2%, 30.8% (P=0.000); 6.3%, 24.8% (P=0.000); 2.7%, 9.1% (P=0.000); 0%, 6.9% (P=0.000); 1.1%, 3.0% (P=0.046); 0.5%, 2.8% (P=0.013); 0%, 2.5% (P=0.002). There were statistically significant difference of disease constitution between the northern of the Yellow River group (796 cases) and the southern of Yellow River group (396 cases) on hypertensive retinopathy in 21.6%, 14.1%(P=0.002); glaucoma in 1.5%, 4.3%(P=0.003); posterior vitreous detachment in 1.6%, 3.5%(P=0.038).
Conclusions :
In teleophthalmology screening of China, cataract, hypertensive retinopathy, diabetic retinopathy, premacular membrane, pathological myopia, glaucoma are common, especially in 50 years old or more. Hypertensive retinopathy is more common in the northern than in the southern of the Yellow River.
