Ickemydriatisk

Ickemydriatisk is an adjective used in ophthalmology to indicate that pupil dilation (mydriasis) is not induced by a procedure, drug, or imaging technique. The term derives from a negating prefix and the root related to mydriasis, and is encountered primarily in some Scandinavian-language medical texts. In English-language ophthalmology, the same concept is usually described as non-mydriatic.

Usage and scope vary by region. Ickemydriatisk often labels methods or agents that do not require pharmacologic or mechanical pupil dilation. It is commonly applied to non-mydriatic imaging approaches, where retinal examination or screening is performed without dilating the pupil, as opposed to mydriatic techniques that enhance visualization through dilation.

Applications and examples. In practice, non-mydriatic (ickemydriatisk) methods include non-mydriatic fundus photography and non-mydriatic retinal imaging used in routine eye exams or screening programs. The concept also appears in discussions of drugs or protocols designed to avoid mydriasis, though pharmacologic choices may be guided by safety and diagnostic needs rather than terminology alone.

Advantages and limitations. Non-mydriatic approaches offer faster examinations, reduced discomfort, and fewer vision disturbances after appointments, making them suitable for children or patients at risk from dilation. Limitations include potentially lower image quality, especially of the peripheral retina, and less flexibility in cases requiring maximized visualization.

Terminology. The term ickemydriatisk is not widely used in English sources; non-mydriatic is the standard English equivalent. The concept remains central to discussions of ophthalmic imaging and diagnostic workflows that minimize or avoid pupil dilation.
