1
Q
less serious ddx of red eye
A
1. corneal abrasion or erosion
2. dry eye
3. chalazion
4. subconjunctival hemorrhage
5. nasolacrimal duct obstruction
6. pterygium
7. conjunctivitis
2
Q
more serious ddx of red eye
A
1. Preseptal Cellulitis
2. Orbital Cellulitis
3. Narrow angle glaucoma
4. Uveitis
5. Scleritis
6. Bacterial keratitis
3
Q
Corneal abrasion or erosion
A
1. Very painful due to extensive innervation in the cornea.
2. Pts have history of trauma or contact lens wear.
4
Q
Dry eye
A
1. Pts present with photophobia and sensation of a foreign body in the eye.
2. May be diagnosed with Fluorescein staining.
5
Q
Chalazion
A
1. Localized swelling and tenderness of eyelid
2. due to infection/inflammation of meibomian glands
(sebaceous glands of the eyelid)
6
Q
Subconjuctival hemorrhage
A
Common, benign problem in which blood vessels within the conjunctiva rupture after sneezing, coughing, eye rubbing, etc.
7
Q
Naso-lacrimal duct obstruction
A
Leads to excess tearing and ocular discharge.
8
Q
Pterygium
A
1. UV-induced benign fibrovascular tumor resulting in elastoid degeneration and a wrinkle that forms over the cornea.
2. May lead to pronounced astigmatism.
9
Q
types of Conjunctivitis
A
1. bacterial
2. viral
3. neonatal
4. chronic
5. allergic
10
Q
Bacterial conjunctivitis:
A
presents with redness and distinct mucopurulent discharge.
11
Q
Viral conjunctivitis
A
(most common) presents with photophobia, redness, watery discharge, and swollen pre-auricular lymph nodes.
12
Q
Neonatal conjunctivitis
A
(viral or bacterial) is rare, but serious.
13
Q
Chronic conjunctivitis
A
(>2 wks.)

often caused by chlamydiae or toxic causes such as neomycin or vasoconstrictors.
14
Q
Allergic conjunctivitis
A
presents bilaterally with itchy eyes, redness, chemosis and mucopurulent discharge.
15
Q
Preseptal Cellulitis
A
1. Inflammation of lids with elevated temp and WBC.
2. Common in children.
3. Treated with abx unless pt. is a neonate…then hospitalize.
16
Q
Orbital Cellulitis
A
1. Inflammation of tissues around the eye resulting in decreased vision, proptosis, abnl papillary response and optic disc swelling.
2. More serious than preseptal cellulitis.
3. Common in children.
17
Q
narrow angle glaucoma
A
1. A true ocular emergency!
2. Narrow angle between iris and cornea prevents fluid drainage leading to rapid increase in intraocular pressure.
3. Anatomic predisposition.
18
Q
narrow angle glaucoma signs
A
1. severe pain
2. HA
3. n/v
4. halo around lights.
19
Q
uveitis
A
Inflammation of anterior chamber of eye associated with collagen vascular or autoimmune diseases.
20
Q
uveitis signs
A
1. photophobia
2. floaters
3. pain
4. decreased vision.
21
Q
scerlitis
A
1. Very painful
2. associated with decreased vision.
3. Often associated. with collagen vascular diseases.
22
Q
Bacterial keratitis
A
1. Ocular emergency!
2. History of trauma or contact lens wear.
23
Q
Bacterial keratitis signs
A
1. pain
2. photophobia
3. decreased vision
4. White spot on cornea corresponding to infection and accumulation of WBCs.
