Description
Estimated cost for Fundus Photography at general public hospitals in China is about ¥15-40, and at Grade 3A hospitals about ¥20-50, varying by hospital tier and region.
Main Uses
Fundus photography is primarily used for diagnosing and monitoring various eye diseases and systemic conditions affecting the eyes. It is particularly useful in detecting and tracking the progression of diabetic retinopathy, glaucoma, age-related macular degeneration, and hypertensive retinopathy. It also aids in the evaluation of optic nerve health and retinal detachment.
Normal Range
For fundus photography, there isn't a numerical 'normal range' as it is more about visual assessment. A normal fundus photograph shows clear and well-defined blood vessels, a healthy optic disc, and no signs of hemorrhages, exudates, or other abnormalities.
Low Values - Possible Causes
Fundus photography does not produce values that can be low; however, certain conditions may lead to under-visualization or misinterpretation: poor image quality due to cataracts, small pupil size, inadequate dilation, media opacities, or technical issues with the camera.
High Values - Possible Causes
Similarly, fundus photography does not produce high values. Abnormal findings might include increased vascular changes, such as in diabetic retinopathy (microaneurysms, hemorrhages), hypertensive retinopathy (arteriolar narrowing, arteriovenous nicking), or macular degeneration (drusen, pigmentary changes).
