Description
Estimated cost for Ocular B-scan at general public hospitals in China is about ¥40-95, and at Grade 3A hospitals about ¥60-120, varying by hospital tier and region.
Main Uses
The primary purposes of an Ocular B-scan Ultrasound include diagnosing and monitoring conditions such as retinal detachment, ocular tumors, vitreous hemorrhage, and cataracts. It is particularly useful in scenarios where direct visualization of the posterior segment of the eye is not possible due to opacities like cataracts or vitreous hemorrhages, and for preoperative assessments in ophthalmic surgeries.
Normal Range
The normal range for an Ocular B-scan Ultrasound typically includes indicators such as the axial length of the eye (22.0-24.5 mm), lens thickness (3.5-5.0 mm), and vitreous cavity depth, which can vary but is generally considered within a healthy range when no abnormalities are detected. The specific values may slightly differ based on the individual's age and other factors.
Low Values - Possible Causes
Low values or abnormal findings in an Ocular B-scan Ultrasound might be caused by: 1) Congenital shortening of the eye, 2) Posterior staphyloma, 3) Scleral thinning, 4) Previous surgical interventions, 5) Certain developmental anomalies.
High Values - Possible Causes
High values or abnormal findings in an Ocular B-scan Ultrasound could be due to: 1) High myopia, 2) Tumors or masses within the eye, 3) Retinal detachment, 4) Vitreous hemorrhage, 5) Inflammation or edema leading to increased tissue density or size.
