Rubeosis
What is rubeosis?
Rubeosis is abnormal blood vessel growth on the iris and the structures in the front of the eye.
What are you looking for when checking angles?
Narrowing, or Closed angles.
What is applanation?
Applanation is flattening of the cornea and measurement of the intraocular pressure (IOP).
What is the colored part of the eye, that regulates the amount of light entering the eye?
Iris
What diagnosis are most commonly associated with Rubeosis?
Diabetics Retinopathy
CRVO
Retinal Artery Occlusions
What are the 2 methods that can be used to check angles?
Slit Lamp and Muscle Light.
What does the IOP have to be, to indicate applanation is needed?
Doctors preference.
What is the small, sensitive area of the retina that gives central vision?
Macula
What part of the eye is Rubeosis found?
These vessels grow along the surface of the iris, first visible at the pupillary margin, and can extend to the iridocorneal angle.
How do you check angles?
Direct the beam towards the corneal periphery at an angle, examine the space between the cornea and the iris.
True or False. Using Goldmann Applanation Tonometry (GAT) is the most accurate way to check IOP.
True.
What is the largest sensory nerve of the eye, that carries impulses for sight from the retina to the brain?
Optic Nerve
How can you determine if a patient has Rubeosis, and what LENS might a Dr use in the exam room to examine the blood vessel growth?
Slit lamp microscope.
Gonioscope Lens
The fluid in the eye can’t circulate and causes increase pressure.
What does it mean if the mires are too thick?
Too much dye.
What is the transparent, colorless mass that fills the rear two-thirds of the eyeball, between the lens and the retina?
Vitreous gel
Left untreated, what can Rubeosis progress into?
Neovascular Glaucoma (NVG)
What diagnosis is associated with narrow or closed angles?
Glaucoma.
Why is it important to applanate?
It is important to measure the IOP because it is a major risk factor in glaucoma and can indicate other ocular disease.
What part of the eye is located behind the iris?
Lens
