What is the normal range for the axial length of the eye in adults?

The normal range for axial length of the eye in adults is typically between 22 to 25 mm. This measurement is crucial in ophthalmology, as the axial length can influence the risk of refractive errors, such as myopia (nearsightedness) and hyperopia (farsightedness).

An axial length of less than 22 mm can often result in hyperopia, while lengths greater than 25 mm are commonly associated with myopia. This range not only reflects the general anatomical structure of the adult human eye but also serves as a reference point for various diagnostic and therapeutic interventions in clinical practice.

Understanding the normal axial length is essential for ophthalmic professionals, particularly when calculating the power of intraocular lenses for cataract surgery or assessing the risk of retinal detachment in patients with elongated eyeballs.
