![Page 6: Management of the Red Eye Anthony Cavallerano, OD VA Boston Health Care System New England College of Optometry Boston, Massachusetts Anthony.cavallerano@va.gov](https://reader033.vdocuments.us/reader033/viewer/2022061616/56649d2a5503460f949fe779/html5/thumbnails/6.jpg)
Blepharitis
Colonization of margin with staphylococcus
Classic sign is fibrin collarette
May lead to loss of lashes and margin ulcerations if severe and chronic
![Page 7: Management of the Red Eye Anthony Cavallerano, OD VA Boston Health Care System New England College of Optometry Boston, Massachusetts Anthony.cavallerano@va.gov](https://reader033.vdocuments.us/reader033/viewer/2022061616/56649d2a5503460f949fe779/html5/thumbnails/7.jpg)
Blepharitis
Staph blepharitis may occur with seborrhea.
Often may develop associated problems.
Marginal infiltrates. Hordeolum. Chalazion. Meibomitis. Marginal infiltrates.
![Page 8: Management of the Red Eye Anthony Cavallerano, OD VA Boston Health Care System New England College of Optometry Boston, Massachusetts Anthony.cavallerano@va.gov](https://reader033.vdocuments.us/reader033/viewer/2022061616/56649d2a5503460f949fe779/html5/thumbnails/8.jpg)
Acute Hordeolum
Acute staph infection of lid
External-glands of Zeiss, moll or lash follicle
Internal- Meibomian Warm compresses Systemic antibiotics if
preseptal cellulitis develops
![Page 9: Management of the Red Eye Anthony Cavallerano, OD VA Boston Health Care System New England College of Optometry Boston, Massachusetts Anthony.cavallerano@va.gov](https://reader033.vdocuments.us/reader033/viewer/2022061616/56649d2a5503460f949fe779/html5/thumbnails/9.jpg)
Chalazion
Obstruction of Meibomian gland with extrusion of lipid into surrounding tissue
Lipogranulomatous reaction, not infectious
May cause astigmatism secondary to pressure on the cornea
![Page 10: Management of the Red Eye Anthony Cavallerano, OD VA Boston Health Care System New England College of Optometry Boston, Massachusetts Anthony.cavallerano@va.gov](https://reader033.vdocuments.us/reader033/viewer/2022061616/56649d2a5503460f949fe779/html5/thumbnails/10.jpg)
CHALAZION TREATMENT
Most slowly shrink and disappear Warm compresses Massage with compression to express
contents thru the Meibomian orifice Oral tetracycline may hasten
resolution secondary to its lipid transforming capability
EXCISION usually from conj side
![Page 11: Management of the Red Eye Anthony Cavallerano, OD VA Boston Health Care System New England College of Optometry Boston, Massachusetts Anthony.cavallerano@va.gov](https://reader033.vdocuments.us/reader033/viewer/2022061616/56649d2a5503460f949fe779/html5/thumbnails/11.jpg)

MEIBOMITIS
Meibomian orifice shows erythema and edema with secretions thick and tenacious
Often diffusely inflamed lid margins
Oral teracycline helpful (doxy 100 BID)
![Page 13: Management of the Red Eye Anthony Cavallerano, OD VA Boston Health Care System New England College of Optometry Boston, Massachusetts Anthony.cavallerano@va.gov](https://reader033.vdocuments.us/reader033/viewer/2022061616/56649d2a5503460f949fe779/html5/thumbnails/13.jpg)
STAPH MARGINAL INFILTRATES
Usually non staining discrete limbal infiltrates which are immune mediated and non infectious
Must first rule out infectious keratitis before using steroids
Treat underlying cause ie. blepharitis
![Page 14: Management of the Red Eye Anthony Cavallerano, OD VA Boston Health Care System New England College of Optometry Boston, Massachusetts Anthony.cavallerano@va.gov](https://reader033.vdocuments.us/reader033/viewer/2022061616/56649d2a5503460f949fe779/html5/thumbnails/14.jpg)
Blepharitis treatment
Lid hygiene, as often as possible Antibiotic ointment to lid margins after
cleaning ie. Bacitracin, erythromycin,rarely sulfacetamide
Lubrication often relieves the foreign body sensation which often accompanies the entity
![Page 15: Management of the Red Eye Anthony Cavallerano, OD VA Boston Health Care System New England College of Optometry Boston, Massachusetts Anthony.cavallerano@va.gov](https://reader033.vdocuments.us/reader033/viewer/2022061616/56649d2a5503460f949fe779/html5/thumbnails/15.jpg)
Phlyctenulosis
Round elevated infiltrate which moves centrally from limbus with “leash of vessels”
Sterile type IV hypersensitivity immune rxn , usually to Staph but may be secondary to T.B., or fungal infections
![Page 16: Management of the Red Eye Anthony Cavallerano, OD VA Boston Health Care System New England College of Optometry Boston, Massachusetts Anthony.cavallerano@va.gov](https://reader033.vdocuments.us/reader033/viewer/2022061616/56649d2a5503460f949fe779/html5/thumbnails/16.jpg)
Phlyctenule Usually resolves spontaneously in 10 –14
days. Photophobia ,tearing and pain. Usually leaves pannus and scarring but
can rarely perforate. Topical steroids are used but treating the
underling cause is essential.

Allergic Conjunctivitis
Usually allergy to air born allergen.
Mediated by IgE. May occur with hay fever,
asthma or rhinitis. Associated with itching,
hyperemia, chemosis, watery ,mucoid discharge.
Topical vasoconstrictors and mast cell stabilizers helpful.
![Page 19: Management of the Red Eye Anthony Cavallerano, OD VA Boston Health Care System New England College of Optometry Boston, Massachusetts Anthony.cavallerano@va.gov](https://reader033.vdocuments.us/reader033/viewer/2022061616/56649d2a5503460f949fe779/html5/thumbnails/19.jpg)

VIRAL CONJUNCTIVITIS
Adenoviral conjunctivitis presents with acute onset of red, watery eyes.
Follicular response worse inferiorly.
Hemorrhagic or pseudomembranous response can occur.
![Page 23: Management of the Red Eye Anthony Cavallerano, OD VA Boston Health Care System New England College of Optometry Boston, Massachusetts Anthony.cavallerano@va.gov](https://reader033.vdocuments.us/reader033/viewer/2022061616/56649d2a5503460f949fe779/html5/thumbnails/23.jpg)

Subconjunctival Hemorrhage Bright blood red eye. Normal vision. No pain. Usually no obvious cause, often told by
others that “eye is red.” May occur in cases of trauma, or in cases of
coughing, vomiting, or straining. If traumatic must do thorough exam to R/O
other pathology.
![Page 31: Management of the Red Eye Anthony Cavallerano, OD VA Boston Health Care System New England College of Optometry Boston, Massachusetts Anthony.cavallerano@va.gov](https://reader033.vdocuments.us/reader033/viewer/2022061616/56649d2a5503460f949fe779/html5/thumbnails/31.jpg)
Subconjunctival Hemorrhage Management
No therapy Reassurance that the condition is not
serious and will resolve in 1-3 weeks Hematologic coagulation studies are
not indicated unless there are associated retinal hemorrhages or many recurrences

Corneal Abrasions
Causes: injury, UV light (welder’s arc), contact lens related, corneal dystrophies, recurrent erosion syndrome, dry eye, corneal anesthesia, infections.
Trauma related abrasions heal very quickly, usually in 24-48 hours.
Recurrent erosions may be sequela of traumatic abrasions.
![Page 33: Management of the Red Eye Anthony Cavallerano, OD VA Boston Health Care System New England College of Optometry Boston, Massachusetts Anthony.cavallerano@va.gov](https://reader033.vdocuments.us/reader033/viewer/2022061616/56649d2a5503460f949fe779/html5/thumbnails/33.jpg)

Alkali Burn Management
Coticosteroids topically can be used for the first 5-7 days as they combat the initial inflammatory process but may potentiate the collagenase activity.
Topical collagenase inhibitors eg. L-cysteine or acetylcysteine or EDTA may reduce collagenase induced stromal ulceration .
Surgical autologous conj . grafts folllowed by PK may be helpful.
![Page 88: Management of the Red Eye Anthony Cavallerano, OD VA Boston Health Care System New England College of Optometry Boston, Massachusetts Anthony.cavallerano@va.gov](https://reader033.vdocuments.us/reader033/viewer/2022061616/56649d2a5503460f949fe779/html5/thumbnails/88.jpg)
