Sample Refraction & Optics Questions
A 70-year-old patient reports increasing difficulty with near vision (reading) despite normal distance vision. This is best explained by:
- A.Presbyopia — age-related loss of lens elasticity/accommodative amplitude
- B.Acute angle-closure glaucoma
- C.Central retinal vein occlusion
- D.Acute conjunctivitis
- E.Optic neuritis
Pathological (degenerative) high myopia, associated with significant refractive error (e.g. -8 to -9 D or worse) and posterior segment complications, is most fundamentally caused by:
- A.Increased lens thickness only
- B.Excessive corneal curvature alone, with normal axial length
- C.A shortened globe
- D.Reduced corneal curvature
- E.Excessive axial elongation of the globe
The near-vision accommodative response (increased lens power for near focus) is produced primarily by:
- A.Relaxation of the ciliary muscle
- B.Pupillary dilation
- C.Contraction of the extraocular rectus muscles
- D.Contraction of the ciliary muscle, relaxing zonular tension and allowing the lens to become more spherical
- E.Contraction of the iris sphincter alone
