Retinopathy and Retinal Detachment (Exam 2) Flashcards
Retinopathy is typically caused by
Type 1 (DM)
HTN
Retinopathy: What is it like?
Splotchy hazy vision
Splotchy and blurry vision
With diabetic retinopathy it is important to
Monitor for progression and take measures progression
Retinal Detachment
URGENT Situation
Retinal Detach: Clinical Presentation
Sudden onset of multiple small floater &/or light flashes
Once detaches:
-Painless “like a curtain coming across field of vision
Repair of Retinal Detachment: Two major methods
- Laser photocoagulation
- Cryopexy
Both seal retinal breaks by creating inflammatory reaction that causes adhesion/scar
Scleral Buckle Procedure
Extraocular procedure
Silicone patch wrapped around eye:
-Indent the globe so that the eyeball moves toward the retina
-Usually under local anesthesia and is outpatient procedure
Scleral Buckle Procedure: Positioning
May be on bedrest with HOB elevated at all times
Scleral buckling Procedure: Topical Eye Ointments
Antibiotics
Anti-inflammatories
Possible dilating agents
Scleral Buckling Procedure: Post Op care
-Activity restriction
-Should not bend over or strain for bowel movements
-Vigorous exercise should be avoided for 3-4 weeks
Pneumatic Retinopexy
Intraocular procedure for detached retina
A gas bubble is injected into the vitreous cavity
Patient needs to be positioned so that the bubble can apply maximal pressure on the retina by the force of gravity
Often head down and to one side
For Pneumatic Retinopexy how long does the patient stay in there certain position?
Several days to several weeks
Post Procedure Detached Retinas GENERAL
90% successful
Prognosis depends on:
-extenet-length-area of detachment
