1
Q
rheuamtoid arthritis
A
chronic systemic autoimmune disease causing inflammation of connective tissue in the synovial joint
- has remission and exacerbations
autoimmune, but could be due to enviroment, or from infections
-triggers formation of IgG immunoglobulins
first phase: rheumatoid synovitis, lymphocytes, and plasma cells increase
next: cartilage is damaged
then: inflammatory response, more damage

Irregular cornea curvature causing light rays to bend unequally
30
visual impairment management
Worry about safety? Can they see? Do they need glasses to see?
care- Glasses and contacts most common, but could have laser surgery, bifocals
Know if patient has contacts, some meds cause contacts to stick to eye, such as chemo, or if patient is unconscious take contact out to avoid damage and infections

pupils need to be dilated, pain and anti inflammatory eye drops gave before surgery, surgeon admins med that breaks lens up, it gets vacuumed, then replaced with another lens.
Post op- shield to sleep - stops from eye rubbing, avoid pressure on front of face such as no bending, bearing down or lifting weights. Eye drop anti inflam. and antibiotic, avoid bright lights
**Patient has to have eye appt 24 hours after surgery so eye pressure can be assessed
complications- hemorrhage, increased eye pressure
44
glaucoma
Increases intraocular eye pressure, putting pressure on optic nerve and could cause blindness over time.
We want to slow the progression of loss of eyesight. Aqueous pressure flows in and out to balance pressure, but with glaucoma this is a issue
symptoms: blurry vision, halos, loss of vision, headache, pain, N/V
Treatment:
open angle- beta blockers, motics, adrenergic agonists.
eye drops preferred- but could still cause systemic effects, monitor BP and HR
