What are 6 signs of diabetic retinopathy?
1- microaneurysms
2- hemorrhages
3- exudates
4- cotton wool spots
5- venous beading
6- IRMA (intraretinal microvascular abnormalities)
What are 3 places that neovascularization due to Diabetic retinopathy can occur?
1- NVD (of the optic disc)
2- NVE (elsewhere)
3- NVI (of the iris)

[always record + or - findings]
Is IRMA a "good Thing"? explain...
Kind of a good thing. these vessels are functional and feed the retina-but- it indicates there has been an ischemic event. Therefore, overall IRMA is "bad".
Is Neovascularization a bad thing? Why?
YES!! These vessels are leaky!
Diabetic retinopathy is a ______ disease.
Do dot/blot hemes, exudates, and CSME indicate ischemic events?
No---leaky vessels
What does CSME stand for?
Clinically significant macular edema.
CSME can occur with DR in _____ stage of the disease.
any stage--so look for it!
What 3 types of DR patients need to be referred?
2- proliferative DR
3- borderline cases where you are sure sure what is going on.
How do "you" (not us) treat CSME?
with lasers.
Does HTN Retinopathy cause symptoms?
No, usually asymptomatic
What are 6 changes that you will see iwth HTN Retinopathy?
1- arteriole narrowing
2- arteriovenous crossing changes
3- copper/silver wire
4- cotton-wool spots
5- flame hemes
6- exudates and macular edema
A ________ is a bright refractile plaque in a retinal vessel.
Hollenhorst Plaque.
A hollenhorst plaque is am atheroma of the ________ (ipsi/contra) carotid artery and/or other vessels.
In what quadrant(s) will you see retinal hemorrhages/dilated/tortuous in a CRVO?
all 4
Name 2 types of CRVO
1- Ischemic
2- non-ischemic (partial/incomplete)
How can you have vision loss in a CRVO?
when you have macular edema
Name 3 specific vision losses with CRVO.
1- central scotoma (over the macula)
2- generalized depression
3- enlarged blind spot
There are lots of causes of CRVO, Name 3.
1- Atherosclerosis
2- HTN
3- glaucoma
What is it called with you have a sector hemorrhage?
A _______ manifests with sudden, painless vision loss.
What is the classic sign of a CRAV?
cherry red spot (this is b/c the macula is avascular and is fed by the choroid)
Name 7 risks for ARMD
1- age (>55)
2- gender (F>M)
3- Race (Cauc)
4- +FHx
5- escessive UV
6- smoking
7- high fat and Chl
ARMD is _____ (dry/wet) 90% of the time.
What is a prevalent sign of ARMD? Where are these located?
Drusen (very deep= RPE/Bruchs)
What are 3 signs of dry ARMD?
1- drusen
2- pigment mottling
3- geographic atrophy of RPE
T or F: patients with ARMD may have a metamorphopsia or a central scotoma.
What are the vitamins that you can recomend a patient with ARMD to take>?
A, C,E, lutein and zinc
What are 3 signs of wet ARMD?
2- subret heme
3- disciform scarring
Myelinated Nerve Fibers occurs in ___ of the population.
_____ is a continuation of normal myelination anterior to the lamina.
Myelinated nerve fibers
What must you distinguish from myelinated nerve fibers?
cotton wool spots (both are white and feathery looking b/c they both occure at the level of the NFL)
What is easily mistaken as papilledema?
buried nerve head drusen
buried drusen consist of ______ globular deposits.
Ca++- like
T of F: an ONH with buried drusen WILL still have a +SVP.
TRUE (papilledema will NOT have a +svp)
When you are looking for drusen, look for ______.
You will seeing thinning of the ONH rim in ______.
______ is basically pathognomic for glaucoma.
Drance hemes
T or F: a patient SHOULD follow the ISNT rule t o be "normal"
True, you want the inferior to be the thickest
What is a drance heme?
hemorrhage at the disc margin
Will you see peripapillary atrophy in glaucoma?
With a __________, (a benign condition) you will see an elevated nasal disc and depressed temporal disc.
malinserted optic nerve
(NOT the same as tilted disc syndrome)
_______ are transient episodes of serous RPE detachments in the macular area.
