Dispensing and Procedures Flashcards
TONO: Reasons for mires becoming thick
Probe touched upper lid and flushed with Fl
TONO: how to insert probe if cyl over 5D
line up appropriate axis with red line on SLB
TONO: angle of illumination system
40-60degrees temporal to patient eye
SLB: width of parallelepipe
1.5-2mm
SLB: how to get retro llumination from fundus
align light beam (matching pupil size or smaller) nearly parallel with examiners visual axis and rotating light so it shines through edge of undilated pupil
GONIO: effect of too little fluid in gonio
air bubbles forming under lens during use
GONIO: set upof illumination and observation
0 displacement, no filters, mag 10-16x, sli beam to medium width 2mm, moderate intensity, vertical orientation
GONIO: FOV of g4 lens
62-64
GONIO: Mag of g4 and high mag g4
1x
1.5x
GONIO: advantage of g3 lens
2 mirrors used for looking at mid/far peripheral retina
GONIO: FOV and mag of g3 lens
60 degrees
1.06x
GONIO: FOV and mag of 1/2 mirror lens
62-64
1x
GONIO: what does corneal wege technique do?
helps ID anterior border of TM in patients where border is difficult to see due to lack of/increased pigment
GONIO: What is Sheie classification based on?
structures seen
GONIO: what is Shaffer system based on?
Based on angular width of angle recess
