- Vision markedly reduced (<20/200) in acute Glaucoma
-
Pupil size and reactivity normal
- Small pupil in Corneal Injury or Iritis
- Dilated non-reactive pupil in Glaucoma
-
Intraocular Pressure normal
- Elevated in acute Glaucoma

- Foreign body
- Factitious
- Idiopathic
VI. Causes: Serious Conditions to Exclude
-
Herpes Simplex Conjunctivitis
- Unilateral Conjunctival/Corneal Inflammation with severe pain
- Concurrent Cold Sores may be present
- Dendritic Ulcers on Fluorescein staining of Cornea
-
Herpes Zoster

- Tiny, rice grain size, gelatinous pale bumps on the Conjunctiva
-
Gonococcal Conjunctivitis (Hyperacute Bacterial Conjunctivitis)
- Severe purulent Eye Discharge, Eye Pain and decreased vision
- Risk of Corneal involvement including Corneal Ulceration
- Obtain cultures and treat systemically for both Gonorrhea and Chlamydia
VII. Labs
- Eye Gram Stain and culture indications
- Corneal Ulceration
- Orbital Cellulitis
- Severe recurrent or refractory eye infection
- Other testing to consider
- Chlamydia PCR
- Giemsa Stain and viral culture for herpes
