Used primarily in ophthalmology for diagnostic purposes, particularly in the assessment of retinal and choroidal circulation during angiography. It acts as a sympathomimetic agent, stimulating dopamine and adrenergic receptors to increase blood flow in the eye, which helps visualize vascular structures. Its effect is temporary and supports the evaluation of ocular disorders such as macular degeneration or diabetic retinopathy. Due to its vasoactive properties, it may also be used off-label in certain cardiovascular diagnostics, though ocular applications remain the primary use.
