proteins• binds to extracellular matrix

(collagen, laminin, fibronectin).

Goal of treatment

Stop progression as early as possibleMostly using medical therapy,

surgeries have a poor prognosisOften dx by biopsy at stage III when

patient is older and may not be able to tolerate the meds well

Leukocyte production, itself, inhibited by following cytotoxic immunosuppr. meds:– Cyclophosphamide-

alkylating agent– Methotrexate,

azathioprine, mycophenolate mofetil-antimetabolites

OCP Patient Education

• OCP is a systemic autoimmune condition best treated with systemic immunosuppressive agents for a few years or more by a specialist/oncologist/hematologist

• Specialist will do a biopsy, rate of positive biopsy 20 to 67% (Jacobiec in Ocular Cicatricial Pemphigoid: A Review of Clinical Features,

Immunopathology, Differential Diagnosis, and Current Management Seminars in Ophthalmology July-September 2011)

• Trouble swallowing? you must seek medical attention, might have to get an endoscopy

• Prognosis: Guarded

A patient on my rotation with OCP

70’s CF, suspected to have OCP about 1 yr agoCC: 1) ocular irritation 2) loss of vision

• 10/11 Cleveland Clinic performed biopsy, recommended Dapsone

A patient on my rotation with OCP

Last December –VA’s ~20/40 in worse eye –Glaucoma on 2 meds d/c’ed 1 med, – severe dry eyes –using Preserved Theratears >4times a day,

d/c’ed – start Oasys PF AT’s, –Durezol bid OU, d/c’ed due to high IOP –hx of Restasis, Punctal Plugs, and bandage Cl’s

A patient on my rotation with OCP

Appearance of ocular surface: –shortened inferior fornices, –staining across entire ocular

surface in both eyes, greatest in conjunctival area, red, painful, burning

A patient on my rotation with OCP

almost 2 months later–VA’s ~20/100 in worse eye; – same appearance + difficulty elevating

eyelid above line of sight due to fibrosis, – restart Travatan, Combigan, –pt asked about immunosuppressives,

was already on azathioprine, pt edu to f/u with PCP and obtain a rheumatologist

A patient on my rotation with OCP

ISSUES

• Patient can’t afford to drive to specialist every time has a worsening of symptoms• Patient does not fully understand

why the medicine she is taking is important and why regular check ups and blood work are necessary
