Amyloidosis is a group of diseases characterized by deposition of abnormal glycoprotein (i.e., amyloid) in tissues leading to structural changes and dysfunction of target organs. Amyloidosis can be both systemic (damage to two or more organ systems) or, less often, local (i.e. localized within a morphological unit). Amyloidosis may affect any organ. Its progression is extremely unpredictable, and the disease can result in a poor outcome. Thus, any practitioner, including an ophthalmologist, should consider the condition as a part of differential diagnosis, and ensure timely appropriate routing and therapy of a patient. Ocular amyloidosis occurs in 4% of all patients with local amyloidosis. Conjunctival amyloidosis is poorly reported, as it is very rare in clinical practice. The disease may be local without association with other systemic manifestations. The authors present a clinical case report of histologically verified amyloidosis associated with synthesis of free light chains of immunoglobulins in both eyes (first, in the right eye and, then, in the left one) without damage to other organs. The patient underwent a surgical intervention for local removal of the affected tissue and an examination to exclude a potential risk of systemic amyloidosis.
Keywords: amyloidosis, local amyloidosis, conjunctival amyloidosis, ocular amyloidosis, AL amyloidosis, systemic amyloidosis.
