1. A -4.00 myope presents to you without glasses. What the furthest he can see clearly? 25cm
2. A +3.00 70 year old hyperope with zero amplitude of accommodation presents to you and demands a Near ONLY glasses for reading at 40cm. What do you Rx? +5.50sph
3. An object is 50cm to the left of a +5.00 lens. Where is the image located? 33cm
4. If you use a retinoscope on a 4 year old boy and find +4.00 hyperopia. In addition to eyestrain from having to sustain accommodation WHAT ELSE are you concerned about? Accommodative Esotropia
5. Explain to a first year optometry student what a cover test (unilateral AND alternating) is checking for? Unilateral is looking for tropia and alternating is looking for magnitude of phoria
6. Draw optical cross of +2.50-3.00×180. What is power of the horizontal and vertical axis? Horizontal = +2.50sph, Vertical = -0.50sph
7. What is a normal phoria at distance and near? Distance- ortho. Near -3exophoria
8. Circle one for each: MYOPIA is when the axial length is too ___________ (long/short) or the Cornea+ Lens powers have too much ___________(convergence/divergence) power. Long and convergence
9. All objects have divergence power. As an object moves further away from you what happens to the divergence power of the object? Goes towards zero
10. Are you more likely to do a cycloplegic refraction on a 5 year kid or a 60 year old? You find out that your 5 year old kid is aphakic would that change your procedure? 5 year old kid. Yes no point in cyclopleging aphakic.
11. Which patient is more likely to develop amblyopia and why? Patient A Rx OD: +1.00sph. OS: +3.00 Patient B Rx OD: plano sph, OS: -3.00sph Patient A because left eye is never being used at distance and near
