This is the first of many optometry clinical encounters where I learned something.
1. Very first patient ever in my life. (I don’t count seeing classmates/friends as first time experiences). 62 year old male contact lens patient who wants multifocals CLs. But he’s doing a modified monovision of sorts where he has a multifocal in one eye and a distance toric lens in the other. I fit him with the CIBA Air Optix Aqua Multifocals in his non-dominant eye and the CIBA Air Optix Toric Lens distance contact lens in his dominant. He LOVES the vision, reads happily and can see distance great and the over-refraction (loose lens in multifocal eye, and the distance I did a sphero- cyl OR through the phoropter) was about plano-ish in both eyes.

The clinical pearl is that I’m doing phorometry (Von Graefe, with no contact lens on), and he sees one (cross of letters) no matter what I do to increase/decrease the prism starting from 12 BI OD, 6 BU OS. It dawned on me after 30 seconds of fiddling with the prism amounts that the guy is probably suppressing.
“Blink a few times for me, sir” (followed by me occluding and then unoccluding what I think to be the “seeing” eye).
“Oh now I see 2″
*nice!*
Clinical pearl #1 is something I knew but in the heat of the moment forgot. Monovision type of patients are more apt to suppress an eye when doing near work than your ordinary patients.
2. Very first primary care patient ever in my life . 87-year old Spanish speaking only patient comes in with one eye barely open. Chief complaint from his son (translator) is that his left eye is always nearly closed. 20/30 in his open (OD) eye, and light perception only (OS) in the eye that he barely keeps open.
Turns out he has a full-blown retinal detachment secondary to diabetic retinopathy that my partner Chad and I spot which Dr. Lee confirms and congratulates us on. So what about the eyelids closing? The patient was able to lift that eye when he desired.
The retinal disparity caused by the retinal detachment between each eye made him voluntarily (and then just out of habit), close his non-seeing eye. When he just came in we were thinking “uh oh, ptosis of some sort,” but it was not the case.
3. Second contact lens patient ever. Female keratoconus in her 20s who has lost one gas permeable lens and needs a new one. Chad and I are at it again. Getting a crazy cover test of 20 exotropia in entrance testing. Dr. Tran comments when we first meet with him with this clinical pearl:
“Haha, don’t do a binocular test on an essentially monocular patient” (at this point she had just one CL on, and she can see hand motion only in the eye without the RGP)
Oops haha.
Other clinical pearls was the patient was getting inferior dimple veiling on the cornea. To fix this we steepened the lens. You might be thinking
“What!?” don’t you want to flatten it out???”
We steepened it to allow for better centration so that the lens would not slide down and we also reduced the optic zone diameter to decrease chances of air bubbles.
That’s it for now!
