oogaanslengte

Oogaanslengte is a Dutch term that appears infrequently in ophthalmic contexts and is not a widely standardized expression. In most Dutch-language sources, the concepts commonly described by this term are referred to as ooglengte (eye length) or aslengte (axial length). When oogaanslengte is encountered, it is often considered a nonstandard or informal variant rather than a formal medical term.

Definition and meaning

In practice, discussions associated with oogaanslengte typically aim to describe the axial length of the eyeball—the distance from the cornea to the retina. This measurement is a key parameter in assessing refractive status and in planning procedures that depend on precise eye geometry.

Measurement

Axial length is measured with optical biometry (such as partial coherence interferometry) or, when necessary, ultrasound A-scan techniques. Reported values in adults generally center around 23 to 24 millimeters, with deviations linked to refractive errors: longer eyes tend to be myopic, shorter eyes hyperopic.

Clinical relevance

The axial length is critical for calculating the power of intraocular lenses in cataract surgery and for understanding refractive development. Accurate measurement helps predict postoperative refractive outcomes and guides decision-making in refractive or spectacle planning.

Terminology and usage

Because oogaanslengte is not a standard term, it is advisable to use ooglengte or aslengte to avoid ambiguity. When encountered in literature, the term is usually a nonstandard variant rather than a distinct clinical concept.
