Clinic: Example Exam Structures Flashcards
PC: Vicroads glasses, no dilation indicated, vision, no prior Rx knowledge (8)
Observe current glasses (quick vert? Make sure to know what type e.g. SV, BF, PALs. Actually check).
VA (habitual D + N) + CT
Screening: Confrontation (re driving), Motility, CT (if not done)
Anterior eye (check for opacities. Check pupil reactivity while in SL)
Posterior undilated (check post pole z UFE)
Retinoscopy
Refraction
IOP/Tono (quick glaucoma check)
PC: GEE re DM checkup/review (8)
VA (D + N) + CT (very quick CT) Anterior + Pupils (e.g. ensure no DM cataract, check for any opacities/ look to see if cornea clear) Dilate Refraction (quick check to see if roughly the same. 5 mins) Screening (Confrontation) Posterior DFE CFP OCT
NB: Anterior and refraction could be swapped around. However, if so, make sure to do pupils separately before dilation, rather than during SL. Also NB: VA may be slightly worse if you do after dilation, so keep that in mind. Can add +1.00 over finding as blur and work backwards to best VA with dilation. However, Final VA findings would be worse. NB: Refraction after drop would be more for patient who had good habitual VA initially (like 6/6). Whereas, if VA was a bit worse, then we could do refraction prior to dilation to try and push 6/6.
How should VA and CT be combined?
DVA –> DCT (look at first letter of line above best) –> NVA –> NCT (look at letter above best paragraph).
What should be done before you start any refraction?
A very quick PD
PC: Full BV workup (11)
VA (D + N) + CT (D + N)
Refraction: incl blur function (trial frame preferred here. If phoropter, switch to trial frame after)
MEM RET
NPA/NPC
A+V facility
Near prentice
ACA
PRC/NRC (D+N) (D = distance prentice) (z prism bar)
NRA/PRA (phoropter with the ruler sticking out)
Binoc X-cyl (optional. Can do MEM RET instead)
MR/VG (optional)
*Do this z best corrected in trial frames (or specs if already best corrected). Measure PD for trial frames prior to MEM RET.
How do you perform NRA/PRA
Start with NRA:
- Px phorop binoc near target (1 size above best)
- add +ve lens until px can’t make clear
- do same for -ve lenses (PRA)
How to perform X-cyl?
+/- 0.50 lens (with -ve cyl axis oriented vertically)
Lag = horizontal lines clearer (closer to retina)
Lead = vertical lines clearer (closer to retina)
When should you fo near VA generally?
After refraction (put near add in frame and adjust near add with flippers while they look at near chart)
