NBEO PART 3 UPDATED EXAMS TEST PAPER
QUESTIONS AND ANSWERS SURE A+
✔✔outer segments of PR contain - ✔✔photopigments
✔✔inner segments of PR contain - ✔✔myoid (makes protein)
ellipsoid (makes energy)
✔✔what is the most common hereditary macular dystrophy - ✔✔stargardts
✔✔UV-C - ✔✔100-280 nm
absorbed by tears/cornea/lens
✔✔UV-B - ✔✔280-315 nm
✔✔UV-A - ✔✔315-400 nm
✔✔helium neon is used for - ✔✔illuminating the retina to view the fundus
✔✔galilean telescope mag goes up to what amount - ✔✔4x
, ✔✔difference between rhegmatogenous and non-rhegmatogenous RD -
✔✔rhegmatogenous indicates that it occurred from a hole or break in retina
non-rhegmatogenous (aka tractional) was caused by something else (DRVOS
conditions for example)
✔✔in hand neutralization, what motion goes with what lens - ✔✔minus lens shows with
motion
plus lens shows against motion
✔✔high mass impact test for ANSI lenses - ✔✔500 g ball dropped from 50 inches
✔✔high velocity impact test for ANSI lenses - ✔✔steel ball 0.25 inches in diameter, fired
at 150 ft/s
✔✔every 1.00 D difference of aniso, how much image size difference is there - ✔✔1%
✔✔if you have 2-3% difference in aniseikonia what do you do - ✔✔Rx lenses with equal
BC and thickness
✔✔if you have >3% difference in aniseikonia what do you do - ✔✔prescribe thin, flat les
to the more plus lens (lens with highest RSM)
✔✔Amblyogenic Refractive Errors - ✔✔Mike is 38, Hannah is 15, now his ass is doing
15-25 yrs
✔✔uncorrected image size for axial myope - ✔✔larger than an emmetrope
✔✔spec correction at spectacle plane for axial myopia - ✔✔SM < 1
RSM= 1
✔✔contact lens correction at corneal plane for axial myopia - ✔✔SM=1
RSM > 1
✔✔uncorrected image size for axial hyperopia - ✔✔smaller than emmetrope
✔✔spectacle correction at spec plane for axial hyperopia - ✔✔SM > 1
RSM= 1
✔✔contact lens correction at corneal plane for axial hyperopia - ✔✔SM=1
