Hi Stuart
It’s been a long time since I have been in the clinic, however as I recall the
most appropriate imaging procedure for disc drusen would be OCT and B Scan
ultrasound. If there is truly drusen present you will see them clearly using
these imaging technologies. As far as FA is concerned I would opt for IV
administration as this method will give you a phased angiogram that you will
not get with oral. As you are using a Spectralis and the patient weight is only
100 lbs I believe that you should get an acceptable FA with 2.5ml of 10%. I do
not however that an FA will be very helpful unless you are trying to identify
transient optic disc ischemia and if so then the IV route will provide a better
chance of seeing this ischemia if present.
Hope this helps
Stephen

Subject: [optimal] More pediatric angiography questions
My satellite office is being sought out by the Riley Hospital ophthalmology
team for help with pt. testing. This is a personal accomplishment for me.
Really proud, and humbled.
Two upcoming visits:
14 year old. Weight: 100lb Working diagnosis: IIH, ON drusen
13 year old. Weight: 100lb Working Dx: ON drusen
My prescription of testing OU [stricly Spectralis FA &/ or Cirrus 5000] would
involve:
Fasting 2 hours prior
Spectralis OCT ON - ONH button [73 sec., 60ym] art at 9
ON photos - IR 30degree, RF//BR 30 deg., FAF 30 & 20 degrees
FA oral, using 10% AK-FLUOR
convert weight for admin. using referenced calculations. i.e. 2 vials 10%
5mL, into 3.5 oz. apple juice.
start timer upon pat. consuming. At 2 minutes start FA using 30 degree lens,
laser at 95% sensitivity. Acquire images every 3 minutes until 15 min. So OU
at 2, 5, 8, 11, 14mins.
Any advice OPTIMAL? Please!
I don't see any reason to choose IV over oral.?
