iLux
Hordeolum
-infection of meiobain gland
-both internal and external
internal
-pain, redness, swelling
-staphylococcus infection
Treatments for Hordeulum
Hot compress
oral antibiotic medication
Chalazion
- chronis inflammation in obstructed meibomian gland
- unresolved hordeolum may form a hard granulomatous chalazion
- generally not too painful
Treatments for Chalazion
Surgical excision
Corticosteriod injection
Blepharitis
- Chronic inflammation
- red lid margin, scaly flakes
Main cause
- Staphylococcus
Treatments for Blepharitis
Hot compress
Lid scrubs
BlephEx (removes the biofilm along eyelid margin)
Eyelid Positions
Entropion- eyelid margin turns INWARD
Ectropion- eyelid turning OUTWARD
Treatments for En/Ectropion
Surgery
dry eye treatment
Conjunctivitis variations
Bacterial
VIral
Allergic
Fungal
Parasitic
Bacterial Conjunctivitis
Bilateral
Purulent discharge
“sticky” eyelids
Treatment for Bacterial Conjunctivitis
Topical antibiotics
Oral antibiotics
Viral conjunctivitis
Unilateral initially (can transfer from one eye to the other)
Tender preauricular node (lymph nodes contains immune cells)
Red, watery eye (pink eye-extremely contagious)
Treatment for Viral Conjunctivitis
Resolves on its own
steroids (speeds recovery) or antivirals (treating HSV)
Allergic Conjunctivitis variations
Hay Fever
Giant Papillary Conjunctivitis
Hay fever

contact lens discomfort
Treatment for GPC
changes lenses more often
reduce deposits on contact lenses; changes cleaning system

growth of pinguecula
treatment for pinguecula and ptergyium

may be secondary to coughing, weightlifting, patient on blood thinners
blood spreads everywhere from tiny blood vessel trapped beneath cornea
looks terrible
Treatment for Subconjunctivitis Hemorrhage
resolves over weeks

Microbial Keratitis
inflammation of the cornea; infection
