Retinal Detachment Flashcards
What can lead to retinal detachment
Happens spontaneously due to changes in vitreous tissue leading to tears or holes
What are the risk factors of retinal detachment
- Age over 50
- Severe myopia (near-sighted)
- Penetrating eye trauma
- Proliferative retinopathy
What is retinal detachment
Reinstall tears away from the layer that supplies oxygen and nutrients
1. Area of detachment increases and visual loss begins
What is the most common site of initial detachment
Superior temporal area
1. Affects first inferior field then superior
2. Central vision remain intact until fovea/macular becomes detached
What increases the risk of permanent vision loss when having a retinal detachment
The longer RD is untreated
What are the signs of retinal detachment
Blurring or altered vision in one eye that eventually results in vision loss
1. No redness, no pain
2. Floaters, flashes of lights
3. Sudden peripheral appearance of floating spots (scotomas)
4. Curtain spreading across field of vision
What will be found of the fundoscopic exam
Hanging / flapping in the vitreous humor like a gray cloud
What needs to happen if a person has a reinstall detachment
Emergent referral to a retinal specialist
*within 1-2 days
How should a person head be positioned if they have a retinal detachment
- Retinal tear is at the lowest point of the eye
*detached portion of retina will fall back with aid of gravity
What is the prognosis of retinal detachment
Re-attachment does not guarantee resorted vision
1. Macula area detached or detachment is of long duration prognosis is worse
If a person does not get treatment how long until complete detachment
6 months
