Eye Infections

Question 1

This is the most common cause of conjunctivitis

Answer 1

Adenovirus

Question 2

This virus can cause a severe form of keratitis known as stromal keratitis

Answer 2

Herpes Simplex VIrus

Question 3

Retinitis caused by this virus has been described as an end-stage disease in AIDS patients.

Answer 3

Cytomegalovirus

Question 4

Recrudescence of this virus can cause ocular complications and outbreaks that have sharp lines of demarcation.

Answer 4

VZV

Question 5

These three viruses can cause acute epidemic hemorrhagic conjunctivitis.

Answer 5

Enterovirus, Coxsackie virus, and Adenovirus

Question 6

Inclusion conjunctivitis, trachoma, and neonatal conjunctivitis can all be caused by this bacterial species.

Answer 6

Chlamydia trachomatis

Different serotypes are responsible for IC vs. trachoma, and these have different transmission routes and epidemiology

Question 7

Keratitis caused by this bacterial species is associated with use of soft contact lenses.

Answer 7

Pseudomonas aeruginosa

Question 8

The spread of a sinus infection to tissues surrounding the eye is the most common cause of:

Answer 8

Orbital cellulitis

Question 9

Endophthalmitis is usually a complication of eye surgery caused by normal flora, but this species is associated with liver abscesses and endogenous endophthlamitis.

Answer 9

Klebsiella pneumoniae

Question 10

Toxoplasma gondii can be a congenital infection or

acquired in this way

Answer 10

Ingestion

Question 11

Keratitis from this fungal pathogen is usually rare, but was responsible for an epidemic related to a contact lens storage/disinfecting solution.

Answer 11

Fusarium solani

Question 12

The inflammatory response to microfilariae from this nematode can eventually lead to keratitis.

Answer 12

Onchocerca volvulus

Question 13

Keratitis caused by this protozoan is often misdiagnosed and should be suspected when chronic keratitis does not respond to therapy.

Answer 13

Acanthamoeba

Question 14

Although it is rare, symptoms similar to macular degeneration may develop years after infection with this organism.

Answer 14

Histoplasma capsulatum

Question 15

Red, swollen eyelids, a gritty sensation, and crusted eyelashes suggest this type of eye infection.

Answer 15

blepharitis

Question 16

Ophthalmia neonatorum (neonatal conjunctivitis) is defined as conjunctivitis that occurs during this time period

Answer 16

first 28 days of life

Question 17

Trachoma is characterized by corneal scarring due to prolonged abrasion of the cornea by at least one of these.

Answer 17

Eyelashes

Question 18

Epithelial keratitis caused by HSV is characterized by observing this (with staining) on the corneal epithelium

Answer 18

Dendritic ulcers

*These are linear, branching structures with bulbs at the end

Question 19

A site in which inflammation in response to a pathogen is often suppressed by various mechanisms is either immune privileged or immune deficient

Answer 19

Immune privileged

Question 20

Either conjunctivitis or keratitis is associated with pain, photophobia, and decreased/impaired vision.

Answer 20

keratitis

Question 21

An infection on the outer eyelid margin that forms a painful bump that usually resolves in a few days is either a stye or a chalazion.

Answer 21

Stye

Question 22

The WHO SAFE strategy applies to either inclusion conjunctivitis or trachoma.

Answer 22

Trachoma

Question 23

Either Neisseria gonorrhoeae or Chlamydia trachomatis causes a rapidly destructive form of neonatal conjunctivitis that usually appears 24-48 hours after birth and is often bilateral.

Answer 23

Neisseria gonorrhoeae

This virus can cause several types of eye infection and is the most common cause of sporadic fatal encephalitis in the US.
