Which finding is NOT typically associated with lens subluxation?

• A. Mild pain
• B. Proptosis
• C. Dyscoria
• D. Variable anterior chamber depth

Answer: (B)

Lens subluxation occurs when zonular fibers are weakened or torn, so the lens becomes displaced and may tilt or move within the eye. This changes the front part of the eye dynamically, so the depth of the anterior chamber can vary with gaze or head position. You’ll often see signs of lens movement such as iridodonesis (a trembling iris) and phacodonesis (lens tremor), and the pupil may appear irregular or have a dyscoria because the edge of the displaced lens can affect the iris. Mild pain can occur if there’s irritation, contact with the iris, or secondary glaucoma from the lens’ movement. Proptosis, or forward protrusion of the eye, is not a typical feature of lens subluxation; it points to orbital disease (like Graves’ ophthalmopathy) or other conditions outside the lens’s position within the eye.
