11.1 Supplemental Tests Flashcards
COA Supplemental Testing (25 cards)
BAT
Brightness Acuity Test- Glare testing
PAM
Potential Acuity Measurment- what could their vision get to (what is it’s over next potential after cataract removal)
LOW POWER lenses for retinal views offer, LOW OR HIGH FILED OF VIEW
LOW POWER= LOW FIELD OF VIEW
LOW POWER lenses for retinal views offer, LOW OR HIGH MAGNIFICATION
High Mag
HIGH POWER lenses for retinal views offer, LOW OR HIGH FILED OF VIEW
High Power= high field of view
HIGH POWER lenses for retinal views offer, LOW OR HIGH MAGNIFICATION
Low mag
Direct illumination vs indirect illumation on slit lamp
Direct means light directly on the structure you want to see. VS. Indirect means light bounces off another structure to a specific other structure then where the light hits
Retro illumination
Shine light through pupil to retina and red reflex back is retro
Does Ishihara color plates test for blue deficiency?
NO! It only tests red/green
Pachymetry
Corneal thickness
Thick cornea in IOP
Fasely high IOP
Thin cornea in IOP
Falsely low IOP
Thick corneas in CL overwear
Think edema/ fluid being trapped/ think haloes around lights and blurred vision
Average corneal thickness
550
Schirmer Test is with or without anesthetic
Without anesthetic
Normal number for Schirmer tear measurement
15 and above= good, below= dry eyes
TBUT stands for
Tear break up time
Normal number for TBUT
5 seconds before tears break, under is dry eyes
Color of rose Bengal dye
Red
Purpose of rose bengal dye
Stains dead cells (like herpes virus on eye)
Purpose of A scan
Measure length from front to back of eye. (Important in calculating IOL for cataract surgery)
A scan AKA
