sensory deficit conditions
clouding of the lens of the eye
What is cataracts?
white outer layer of tissue that covers the eyeball
What is the sclera?
occurs when the component of the retina responsible for vision is not able to function
What is age related macular degeneration?
diabetes mellitus, hypertension, use of steroids, and smoking
What are risk factors for cataract development?
intraocular pressure higher than normal in the absence of optic nerve damage or visual field loss
What is ocular hypertension (OHT)?
Irreversible degeneration of the macula
What is macular degeneration?
provides protection to the front and interior of the eye by producing tears as lubrication
What is conjunctiva?
triggered by abnormal growth of blood vessels underneath the retina
What is wet AMD?
interfere with blood clotting and may cause bleeding during a procedure, usually held prior to surgery
What are anti-coagulants?
normal intraocular pressure
What is 10-21 mmHg?
Increased intraocular pressure due to the buildup of fluid that compresses the optic nerve
What is glaucoma?
gland responsible for making tears to provide protection/lubrication to the eye
What is the lacrimal structures?
smoking, hypertension, elevated cholesterol levels, obesity, and family history
What are risk factors for AMD?
used to assess visual acuity
What is the Snellen eye chart?
classification used in treatment of glaucoma, side effects include dry mouth/nose, headache, & burning
What is alpha agonist eye drops? (brimonidine, iopidine)
occurs when the retinal tissue detaches from the blood vessels of the posterior eye
What is retinal detachment?
area between the sclera and retina that contains blood supply & connective cells
What is choroid?
color code medications, remove floor clutter, remove area rugs, and ensure adequate lighting
What are safety measures for AMD patients?
time span that progressive visual improvements occur following cataract removal surgery
What is 8 weeks?
sudden onset of vision loss, considered urgent situation, requires emergent treatment, due to complete obstruction of aqueous humor outflow
What is angle closure or narrow angle glaucoma?
eye disorder in patient's with diabetes, resulting in deficit in vision acuity & permanent loss of vision caused by decreased blood flow to the rear of the eye
What is diabetic retinopathy?
portion of the eye that produces clear fluid
What is ciliary body?
the use of a laser beam to target and eliminate abnormal blood vessels in the rear of the eye
What is photodynamic therapy (PDT)?
most effective treatment option if cataracts interfere with ADL's
What is surgical intervention?
classification used in treatment of glaucoma, side effects include bradycardia & decreased energy
What is beta blocker eye drops? (timolol, betaxolol)
