Conjunctiva & Sclera

Look at the bulbar (the eye) & palpebral (inside of the lids) conjunctivaInjection & erythema; what is the distributionDischarge; watery, mucous or membranousWhat do I see?

Page 3: Trichiasis

Scleritis or episcleritis

Page 4: Trichiasis

Scleritis• Red painful eye with decreased vision• Often associated with underlying collagen vascular

disease• RA, Lupus

• Diffuse, Nodular, Necrotizing forms• Refer!!

• Requires systemic immunosuppression• Indocin, Prednisone, Cyclosporin, Cytoxan

Page 5: Trichiasis

Rheumatoid Arthritis

Page 6: Trichiasis

Subconjunctival Hemorrhage

• Dramatic but harmless• Sneezing,coughing, straining,eye rubbing

• Associated with anticoagulation• Aspirin

• If no obvious cause and associated with bruising or repetive than:CBC, Platelet count, Bleeding time, PT/PTT

Subconjunctival Hemorrhage

Page 8: Trichiasis

Pterygium

Page 9: Trichiasis

Pterygium• Benign fibrovascular tumor (UV induced)

• Elastoid degeneration (wrinkle)• Often become inflamed• Treatment:

• Artificial Tears, Sunglasses, Short term use of vasoconstrictors

• Refer if large or conservative fails• Conjunctival Auto graft with Glue

Pingueculum

Page 11: Trichiasis

Bacterial Conjunctivitis

Page 12: Trichiasis

Conjunctivitis: Bacterial

• Redness and mucopurulent discharge• Minimal discomfort • Vision minimally affected

• Treatment• Will resolve without treatment• Polytrim (polymixin-trimethoprim) q 2 hours the

first day then QID for 1 week

Page 13: Trichiasis

Gonoccocal Conjunctivitis

Page 14: Trichiasis

Hyperacute Purulent Conjunctivitis

• Sudden onset with rapid progression• Bilateral

Page 15: Trichiasis

Case 4

Page 16: Trichiasis

Conjunctivits: Viral (EKC)• U. resp. Infection• History of contact

• VERY CONTAGIOUS• Sx’s: Photophobia, redness, watery discharge

• Bilateral but asymmetric• Preauricalar node• Treatment: None--Avoid Topical Steroids!!

Page 17: Trichiasis

Allergic Conjunctivitis

Page 18: Trichiasis

Conjuntivitis: Allergic

• Itching• Seasonal• Bilateral• Mucopurlent discharge, no pre-auricular

node• Redness, Chemosis

Page 19: Trichiasis

Allergic Conjunctivitis: Treatment

• Avoidance• Associated with Dry Eye

• Wash eyes out with tears• Cold Compresses• Ocular antihistamines/mast cell stabilizers

• Patenol, Alocril, Zaditor

Cornea

ClarityHaze, or scars (including surgical)PterygiumEpithelium (use fluorescein dye & a cobalt blue filter to examine the epithelium for defects including punctate erosions, abrasions, ulcers, dendrites)What do I see?

Page 21: Trichiasis

Case 5

Page 22: Trichiasis

Abrasion

• History of Trauma or Contact Lens wear• Very Painful: More pain nerves per mm

than any other location• Diagnosis:

• Drop of Proparacaine

• Flouroscein lights up epithelial defect

Page 23: Trichiasis

Treatment

• Relief of Pain and Rapid Visual Rehabilitation• Antibiotic ointment, dilation, patch• Bandage Contact lens

• With Antibiotic Drops• Topical NSAID: Acular or Voltaren

• Recommend Follow-up (Infection)

Page 24: Trichiasis

Patching

Page 25: Trichiasis

Dry Eye

• Postmenopausal women• Sometimes associated with Arthritis

• Lupus, RA, Sjorgren’s• Often related to climate/humidity• Exacerbated by systemic medications

• Diuretics, antihistamines, and anti-depressant

Page 26: Trichiasis

Dry Eye: Symptoms

• Foreign body sensation• Photophobia• May complain of redness• Associated blepharitis or allergic

conjunctivitis is common

Page 27: Trichiasis

Dry Eye: Diagnosis

• Schirmer’s test• Fluorescein staining• White, quiet eye is common

Page 28: Trichiasis

Flourescein Staining

Page 29: Trichiasis

Rose-Bengal

Page 30: Trichiasis

Schirmer Test

Without anesthesia• Measures reflex tear

secretionWith anesthesia• Eliminates stimulated

tearing

Page 31: Trichiasis

Dry Eye: Treatment• Artificial Tears

• Watch for preservative toxicity• Saturation therapy• Preservative free drops

• If using more than 4/day• Consider punctal occlusion or Restasis

(Cyclosporine)

Page 32: Trichiasis

Restasis

• Cyclosporine (.05%) in lipid vehicle• Treats surface inflammation

• Inhibits T-cell infiltration of lacricmal gland• Burns on instillation• Administer BID

Page 33: Trichiasis

Dendrite

Page 34: Trichiasis

Treatment of HSV Keratitis

• Topical Antivirals Trifluridine• Systemic Acyclovir or Famvir if

immunosuppressed or extensive associated skin lesions

Page 35: Trichiasis

Chemical Injuries

• Acid or Alkali?• Cation determines speed of penetration

• NH4+, Na+,K+,Ca++ (OH)

• Battery Explosions• Chemical plus blunt force trauma• Foreign body

Page 36: Trichiasis
Page 37: Trichiasis
Page 38: Trichiasis

Chemical Injuries

• Irrigate, Irrigate and Irrigate• Topical anesthetic, 7th nerve block helpful

• Prognosis determined by:• Type of chemical (acid vs. alkalai)• pH• Length of exposure• TIME BETWEEN EXPOSURE AND IRRIGATION

REFER as soon as possible

Iritis/Uveitus

• “Arthritis of the Eye”• Associated with Collagen Vascular disease• HLA-B27 associated• Crohn’s disease, RA, Lupus

• Sign & Symtom: Photophobia, Floaters, Red Eye, Pain, Decreased vision

• Circumlimbal flush
