TX for atrophic macular degeneration
Statin therapy
smoking cessation
Daily vitamin/antioxidant
SCT
TX for exudative macular degeneration
IV endothelial growth factor
Smoking cessation
Daily vitamin/antioxidant
Photodynamic therapy
Two types of ischemic macular degeneration
Anterior
Posterior
Anterior ischemic macular degeneration affects what?
Optic disc
Anterior ischemic macular degeneration is associated with?
Age
Posterior ischemic macular degeneration affects what?
Area behind the eye
Posterior ischemic macular degeneration is assoc. with?
Spinal surgery
Sudden, painless monocular vision loss
Jaw pain, scalp tenderness, neck pain
Impaired color vision
Ischemic macular degeneration
Retinal ruggae
Retinal detachment
Demyelination and inflammation of optic nerve
Optic neuritis
Vision loss occur over hours to a week
Eye pain that’s worse with movement
MS, marcus gunn pupil
Optic neuritis
Cotton wool spots, retinal hemorrhages, hard exudates, occluded/dilated vessels, lack of new blood vessels
Nonproliferative diabetic retinopathy
Excessive floaters w/ hemorrhage, neovascularization, cotton wool spots, pre-retinal hemorrhages
Proliferative diabetic retinopathy
Retinal thickening and hard exudates within 500 microns of the fovea
Clinically significant macular edema
Bilateral optic nerve swelling due to increased cranial pressure
Papilledema
Unilateral optic nerve swelling and marcus gunn pupil
Optic neuritis
CN 7 Palsy causes
Ectropion
Fever, sore throat, follicles on palpebral conjunctiva
Pre-auricular and anterior cervical lymphadenopathy
Adenovirus
Viral conjunctivitis
Mucopurulent exudate in fornix
Adhesion of eyelids
Bacterial conjunctivitis
Bilateral pruritis
Stringy mucoid discharge
Allergic conjunctivitis
Profuse purulent discharge
Preauricular adenopathy
Neisseria conjunctivitis
Conjunctivitis and conjunctival scarring in area with overcrowding and poor access to water
Chlamydia conjunctivitis
Episcleritis vs subconjunctival hemorrhage
Episcleritis - diffuse redness, engorgement of episcleral vessels
Subconjunctival - more defined, looks more like blood pooling
Which crosses into the cornea?
Pterygium or Pinguecula?
Pterygium
The cycle of aqueous production and drainage occurs over?
100 minutes
Where does the greatest resistance to aqueous outflow occur?
“Anterior chamber angle”
Trabecular network, junction of cornea and iris
Overproduction of aqueous with normal outflow
Open angle glaucoma
Blockage of aqueous drainage
Angle closure glaucoma
Glaucomatious cupping
≥ 0.6
Epithelial dendrites seen w/ fluorescein staining
HSV Keratitis
