What is the normal axial length of the eye?

• A. 20-22 mm
• B. 23-25 mm
• C. 26-28 mm
• D. 24-26 mm

Answer: (B)

The normal axial length of the eye typically ranges from 23 mm to 25 mm. This measurement is crucial because the axial length can significantly impact vision. When the eye is too long or too short, it can lead to refractive errors such as myopia (nearsightedness) or hyperopia (farsightedness). Understanding the axial length helps in guiding procedures such as cataract surgery and assessing the risk for conditions like retinal detachment. The range provided in the correct answer reflects the average for an adult human eye and is a standard measurement used in ophthalmology. Recognizing this normal range is fundamental for ophthalmic professionals in diagnosing, managing, and treating various eye conditions.
