Ocular Cicatricial Pemphigoid (OCP), also known as Mucous Membrane Pemphigoid, is a rare autoimmune disorder that primarily affects the mucous membranes and skin, particularly in the eye area. It is characterized by chronic inflammation and scarring of the mucous membranes, including the conjunctiva, transparent layer covering the white part of the eye and the oral mucosa inside the mouth.
The condition is caused by an autoimmune response, where the body’s immune system mistakenly targets healthy tissues, leading to inflammation and scarring. In the case of OCP, the immune system targets proteins within the mucous membranes and skin, causing blistering, erosions, and subsequent scarring. This scarring can lead to various complications, especially in the eyes.
Epidemiology
OCP can affect individuals of any age, but it is more commonly diagnosed in middle-aged to elderly individuals. It tends to occur more frequently in women than in men, with a female-to-male ratio of approximately 2:1.
The prevalence of OCP may vary based on geographic regions. It has been reported more frequently in certain populations, such as those of northern European ancestry.
The incidence and prevalence of OCP are relatively low compared to other autoimmune disorders. Due to the complex and variable nature of OCP symptoms, it can be challenging to diagnose accurately.
Anatomy
Pathophysiology
OCP is considered an autoimmune disorder, meaning the immune system attacks its own healthy tissues instead of foreign invaders. In OCP, autoantibodies, which are immune proteins, target specific components of the basement membrane zone.
Autoantibodies targeting BP180 and BP230 disrupt the connection between the epithelial cells and the basement membrane, leading to separation of these layers. Cytokines are signaling molecules that regulate immune cell communication and activity.
Etiology
Genetic predisposition appears to play a role in increasing the susceptibility to OCP. Certain human leukocyte antigen (HLA) alleles have been associated with an increased risk of developing autoimmune disorders, including OCP.
HLA genes are involved in regulating the immune system’s response to foreign substances and self-tissues. Specific alleles, such as HLA-DQB10301 and HLA-DPB10401, have been linked to a higher risk of OCP.
Individuals with a family history of autoimmune disorders may have a higher likelihood of developing OCP.
Genetics
Prognostic Factors
The initial severity of OCP can impact the long-term prognosis. Individuals with more advanced diseases at the time of diagnosis, characterized by significant ocular involvement, extensive scarring, and impaired vision, might face greater challenges in managing their symptoms and preserving their vision.
The extent and severity of ocular involvement are crucial prognostic factors. If OCP primarily affects the conjunctiva and leads to frequent and severe scarring of the cornea, it can significantly impact visual acuity and quality of life.
The response to treatment plays a critical role in determining the prognosis. The presence of other medical conditions can impact the prognosis of OCP.
The age at which OCP is diagnosed can influence the prognosis. Older individuals might have a higher risk of severe complications due to age-related changes in the eye and reduced regenerative capacity.
Clinical History
OCP can occur in individuals in their 40s, 50s, and 60s. This age group is more likely to experience the onset of OCP symptoms.
OCP is often diagnosed in individuals over the age of 60. The risk of developing OCP tends to increase with age.
Physical Examination
Ocular Examination:
Measurement of visual acuity using an eye chart to determine the individual’s ability to see clearly at various distances.
A specialized microscope with a light source is used to examine the front structures of the eye, including the cornea, conjunctiva, and eyelids.
Examination of the conjunctiva for signs of inflammation, redness, swelling, and scarring.
Evaluation of the cornea for signs of scarring, erosions, and other changes that might impact visual acuity.
Evaluation of tear production and quality to assess dry eye symptoms, which are common in OCP.

Cicatricial alopecia refers to a group of hair loss disorders that involve inflammation and scarring of hair follicles. Some individuals with OCP may develop cicatricial alopecia as a related condition, as both disorders involve scarring of the affected tissues.
OCP can present with oral involvement similar to oral lichen planus, another autoimmune disorder that affects the oral mucosa. The two conditions might have overlapping symptoms and characteristics.
Associated activity
Acuity of presentation
OCP presents with a gradual onset of symptoms. Individuals might initially experience mild eye discomfort, dryness, redness, and a foreign body sensation. These symptoms might be attributed to other common eye conditions, leading to potential delays in diagnosis.
OCP commonly affects both eyes, often presenting with bilateral symptoms. This bilateral involvement distinguishes OCP from other eye conditions that might affect only one eye.
Eye redness, irritation, and a sensation of burning or grittiness are often early symptoms of OCP. These symptoms can be chronic and progressive, leading to persistent discomfort. As OCP progresses, individuals might develop conjunctival scarring, which can lead to changes in the appearance of the conjunctiva.

Immunosuppressive drugs are often used to reduce the need for high doses of corticosteroids, minimizing their side effects. Regular monitoring and potential side effects are important, as these medications affect the immune system.
Azathioprine: Azathioprine is a prodrug that gets converted to active metabolites that inhibit the proliferation of immune cells, particularly rapidly dividing cells.
Azathioprine is commonly used in the treatment of OCP to suppress the autoimmune response responsible for inflammation and tissue damage. Azathioprine can help reduce the need for high doses of corticosteroids, minimizing their side effects.
Cyclophosphamide: Cyclophosphamide is a potent immunosuppressive and cytotoxic agent that inhibits the proliferation of immune cells.
Cyclophosphamide might be considered in severe cases of OCP that are not responding well to other treatments. It can be effective in controlling severe inflammation and preventing disease progression.
Methotrexate: Methotrexate is an immunosuppressive and anti-inflammatory medication that inhibits DNA synthesis and suppresses immune cell activity.
Methotrexate is used to manage the autoimmune response and inflammation in OCP. Methotrexate can be effective in controlling symptoms and preventing disease progression.
Systemic steroids, also known as corticosteroids these medications help suppress the autoimmune response responsible for the inflammation and tissue damage seen in OCP.
Prednisone: Prednisone is a synthetic corticosteroid that mimics the effects of natural hormones produced by the adrenal glands. It suppresses the immune response and reduces inflammation.
Prednisone might be used in cases of moderate to severe OCP to rapidly control inflammation and alleviate symptoms.
Immunomodulators are medications that help regulate and modify the immune response.
Immunomodulators are used to control inflammation, suppress the autoimmune response, and prevent further damage to ocular and mucous membrane tissues.
Infliximab: Infliximab is a monoclonal antibody that inhibits tumor necrosis factor alpha (TNF-alpha), a pro-inflammatory cytokine.
Infliximab might be considered in severe cases of OCP that are not well-controlled with other treatments.
Etanercept: Etanercept is a soluble TNF-alpha receptor that binds to TNF-alpha and prevents its interaction with cell receptors.
Rituximab: Is a biologic agent that targets specific immune cells called B cells. It depletes these cells from the bloodstream, reducing the production of autoantibodies and suppressing the autoimmune response.
Rituximab might be considered in cases of severe OCP that are refractory to other treatments or when other treatments are not well-tolerated. Rituximab is administered via intravenous infusion, typically given in multiple sessions over a period of several weeks.
OCP is an autoimmune disorder that primarily affects the mucous membranes and skin, leading to inflammation, scarring, and damage.
IVIG contains a concentrated mixture of immunoglobulins derived from healthy donors and can modulate the immune response.
Intravenous Immunoglobulin (IVIG): IVIG contains a diverse range of antibodies that can interact with various components of the immune system.
It can have immunomodulatory effects, including inhibiting the production of autoantibodies and modifying the immune response.
Corneal Transplantation: Corneal transplantation involves replacing the damaged cornea with a healthy donor cornea. This procedure can restore visual function and alleviate corneal scarring.
Conjunctival Grafting: Healthy tissue from unaffected areas of the conjunctiva is grafted onto areas with scarring and damage. This procedure helps restore the integrity of the ocular surface.
Punctal Plugs: Punctal plugs are small devices inserted into the tear drainage ducts to block tear drainage. This helps maintain moisture on the ocular surface.
Punctal plugs can be used to alleviate dry eye symptoms associated with OCP.
Diagnosis and Assessment Phase: The characteristic symptoms, ocular involvement, and mucous membrane changes guide the diagnosis.
Treatment Initiation Phase: Initial treatment focuses on alleviating symptoms such as dryness, irritation, and discomfort. Topical corticosteroids and lubricating eye drops might be prescribed.
Management Phase: OCP management often involves a trial-and-error approach to find the most effective treatment regimen with the least side effects.
Complication Prevention Phase: Measures to protect the cornea from damage include lubricating eye drops, eye shields, and interventions to prevent exposure.
Surgical Interventions Phase: Surgical interventions such as amniotic membrane transplantation, conjunctival grafting, and other procedures might be considered to manage complications, scarring, and damage to the ocular surface.
Long-Term Maintenance Phase: Long-term use of immunosuppressive medications might be necessary to manage chronic inflammation and prevent relapses.
