Ocular cicatricial pemphigoid (OCP) is a rare autoimmune disorder that primarily affects the eyes. It occurs when the body's immune system mistakenly attacks the tissues of the conjunctiva, leading to inflammation and scarring. This condition can result in symptoms such as redness, irritation, and vision problems, and may ultimately lead to blindness if not treated. The exact cause of OCP is not fully understood, but it is often associated with other autoimmune diseases. Treatment typically involves medications to reduce inflammation and suppress the immune response, and in some cases, surgical interventions may be necessary to preserve vision and eye health.
