Optometry Test 2 Questions with Answers

Optometry Test 2 Questions with Answers Explain some of the theories as to why people exhibit lag of accommodation - Answer-1- is lazy lag, once we have accommodated enough to make it readable, we stop there 2- the near triad is all working together, so convergence, pupil constriction, and accommodation are all working together. So by slightly inhibiting the accommodative system, the eyes are able to converge less, which makes the process easier on the viewer. *protection from over convergence, avoid the subsequent diplopia* What result is expected in MEM and what is not, and why? - Answer-Lag or with motion is expected if the pt is wearing their proper RX, due to the lazy and triad theories. Lead or against *(over accommodating)* is not expected, and might suggest *high exophoria* and *low PFV* An MEM value under +0.25 indicates (3 things) - Answer-high exophoria low PFV (poor convergence) overaccommodation An MEM value over +0.75 indicates (3 things) - Answer-High esophoria low NFV (poor divergence) underaccommodation MEM finds +1.25 diopters in both meridians. If the patient IS wearing their proper RX of +1.50, this can suggest__ ___ ___, but if the patient is not wearing the Rx the results are showing____ - Answer-If they are wearing the rx, the results indicate high eso, poor NFV, or under accommodation. Without the Rx, the results are just the uncorrected hyperopia showing through What would A/M MEM results indicate in an uncorrected myope? - Answer-the uncorrected myopia showing through, basically you are doing normal ret What would A/M MEM results indicated in a corrected myope? - Answer-over accommodating High exo poor convergence
