What do you see on Fundoscopy of diabetic retinopathy?
On fundoscopic exam, diabetic retinopathy is characterized by cotton wool spots, flame hemorrhages, dot-blot hemorrhages and boat hemorrhages.
What does glaucoma look like on Fundoscopy?
Glaucoma results in irreversible loss of nerve fibres, leading to an appearance of “cupping” or an increased vertical cup-to-disc ratio (C/D ratio).
Can diabetic retinopathy cause glaucoma?
Diabetic retinopathy can cause abnormal blood vessels to grow out of the retina and block fluid from draining out of the eye. This causes a type of glaucoma (a group of eye diseases that can cause vision loss and blindness).
What is the third stage of diabetic retinopathy?
The third stage, severe nonproliferative retinopathy brings with it more blocked blood vessels, which leads to areas of the retina no longer receiving adequate blood flow. Without proper blood flow, the retina can’t grow new blood vessels to replace the damaged ones.
What do you see on a Fundoscopic exam?
Ophthalmoscopy (also called fundoscopy) is an exam your doctor, optometrist, or ophthalmologist uses to look into the back of your eye. With it, they can see the retina (which senses light and images), the optic disk (where the optic nerve takes the information to the brain), and blood vessels.
How is diabetes related to glaucoma?
Diabetic retinopathy, which is a complication of diabetes, can result in damage to the blood vessels in your retina. This can cause abnormal blood vessels to grow in your eye, which can block your eye’s natural drainage system and eventually lead to glaucoma.
Why do diabetics develop glaucoma?
High blood sugar levels can damage the back of your eyes, the area called your retina. Untreated diabetic retinopathy can lead to blindness after a few years. You could see damage to the blood vessels in your eyes as a result. A diagnosis of diabetes also doubles your risk for developing glaucoma.
What are the grades of diabetic retinopathy?
Table 1.
| Grade | Features | Outcome |
|---|---|---|
| R0 | No disease | Rescreen in 12 months |
| R1 | Mild background DR Including microaneurysms, flame exudates, >4 blot haemorrhages in one or both hemifields, and/or cotton wool spots | Rescreen in 12 months |
| R2 | Moderate background DR >4 blot haemorrhages in one hemifield | Rescreen in 6 months |
Is glaucoma a complication of diabetes?
Glaucoma may occur amongst people with and without diabetes, and can be a complication of diabetes if retinopathy develops. Glaucoma is caused by an excess amount of fluid pressing on the nerve at the back of the eye.
Can diabetes increase risk of glaucoma?
Diabetes is associated with a significantly increased risk of glaucoma.
