The Impact of Systemic Light Chain Amyloidosis on Eyes

Study Purpose and Principle: Amyloidosis is a group of diseases characterized by the deposition of amyloid proteins in tissues and organs throughout the body, with common affected organs including kidneys, heart, nervous system, gastrointestinal tract, and liver. Nowadays, nearly 40 different proteins have been found to form amyloid fibrils in body, among which Systemic Light Chain (AL) Amyloidosis is the most common type of systemic amyloidosis. AL amyloidosis is a plasma cell disorder, with its precursor protein originating from free light chains produced by abnormal plasma cell clones, which form amyloid substances that deposit in tissues and organs causing lesions. In terms of incidence, the incidence of AL amyloidosis is 8-10 cases per million person-years in the United States and is considered a rare disease in our country. AL amyloidosis has an insidious onset, diverse clinical manifestations, and is prone to misdiagnosis and missed diagnosis in clinical practice. The prognosis also has strong heterogeneity and is closely related to the extent of organ involvement at the time of diagnosis. In the past, the incidence of eye involvement in systemic AL amyloidosis patients was low, with various manifestations, only reported as case reports, and not regularly followed up with systemic treatment. Based on this, this project aims to assess the involvement of eyes and its appendages in patients with different stages of systemic light chain amyloidosis, with the goal of clarif…
