What is Ocular Ultrasound?
Ocular ultrasound, also referred to as ocular echography or B-scan is a non-invasive and painless test utilised in clinical settings to evaluate the structure of the eye and identify potential abnormalities. Similar to other ultrasound procedures, ocular ultrasound relies on the reflection of sound waves to generate detailed images of the eye’s internal structures, aiding in diagnosis and treatment planning.
Ocular ultrasound is recommended in specific situations where conventional eye examination is limited due to media opacities, these include:
- Suspected retinal detachment
- Vitreous hemorrhage
- Ocular mass or tumours
- Inflammatory disease
- Dense cataracts or corneal opacities
Fluorescein Angiography and Indocyanine Green (ICG) Angiography
Fluorescein Angiography and Indocyanine Angiography are diagnostic tests used to examine the blood flow in the retina. It involves injecting a special dye called Fluorescein or ICG into a vein in your arm, then taking a series of photographs as the dye circulates through the blood vessels in the retina. The test identifies areas of leaking or abnormal blood vessels, blockages, swelling, or other changes that may affect the health and function of the retina.
Fluorescein Angiography and Indocyanine Angiography are often used to diagnose and treat conditions such as:
- Macular Degeneration
- Diabetic Retinopathy
- Macular Edema
- Retinal Vascular Disease
Wide view Retinal Photography and Autofluorescence
Wide-view retinal photography uses a specialized camera that takes images of your retina to detect and monitor macular and retinal conditions. In addition to macular pathologies, ultra-widefield retinal photography is particularly useful in the assessment of peripheral retinal pathologies and retinal tears. Autofluorescence is a special non-invasive imaging technique helpful in the detection of generalized retinal disorders such as retinal degeneration and dystrophies caused by genetic mutations.
