Hordeolum - SA –> warm compress –> histo path to r/o CA if recurrent
Hard painful –> painLESS rubbery lid nodule, granulomatous lesion of meibomian glands
Chalazion
– persistence or recurrence = sebaceous carcinoma –> get HISTOPATHOLOGY

Optic neuritis - ASSOC w/ MS
S/P cataract surgery –> dec vision, exudates in anterior chamber, edematous conjunctiva
Postoperative endophthalmitis = Vitreous infection –> Abx or extraction
Transient vision loss w/ changing head position, enlarged blind spot, morning HA
Papiledema –> CT
Profuse watery eyes, hyperemia, edema of eyelids, asthmatic pt
Allergic conjunctivitis –> anti-histamine or mast cell stabilizing drops (olopatidine)
URI, watery discharge, fall, most common conjuctivitis, preauricular LAD
Viral conjuctivitis/pink eye –> warm/cold compress
Painful eye w/ purulent discharge w/ crusting
Bacterial conjuctivitis = Strep pneumo –> erythromycin, fluoroquinolone w/ contacts
Conjunctivitis 1st 24hrs, b/l non-purulent
Chemical (Ag-nitrate) = supportive
Conjunctivitis day 2-5, b/l eyelid swelling, discharge
Gonococcal –> IM//IV ceftriaxone OR topical erythromycin
Conjunctivitis day 5-14, u/l, some eyelid swelling, injection, mucopurulent
Chlamydia
Blood-stained eye discharge
Chlamydia –> ORAL Erythromycin 14d can –> hypertrophic pyloric stenosis
Most common blindness in world, Trachoma
Chlamydial (A,B,C) –> tetracycline or erythromycin
4 y/o unilateral conjunctivitis, nasal discharge, neovascularization/pannus, EGYPT
Trachoma –> topical tetracycline or oral Azithro
CAN move eyes, inflammation around eyes
Pericellulitis –> abx
Can’t move eyes, inflammation around eyes
Orbital cellulitis –> CT scan –> I&D + Abx
Orbital cellulitis vs. preseptal
Orbital - diplopia, pain, proptosis, vision impairment –> IV Abx vs. oral
