The term amyloidosis gathers an heterogenous group of disorders characterized by the extracellular deposition of amyloid fibrils. Among these, Light-chain (AL) amyloidosis, also known as primary amyloidosis, is the most common form. It is a rare systemic disease with an estimated annual incidence of 9.7 to 14.0 cases per million people [
1,
2]. It is characterized by the extracellular tissue deposition of amyloid fibrils derived from kappa or lambda monoclonal light chains. These proteins are synthesized by a clonal population of plasma cells in the bone marrow [
3]. Excluding the central nervous system, amyloid deposits can affect and damage all organs and more commonly the heart, kidneys, liver. The disease progresses insidiously, and the general symptoms are usually non-specific (asthenia or dyspnea) often causing diagnostic delay. Unlike secondary (AA) amyloidosis, which does not affect the ocular globe, AL amyloidosis can involved various ocular tissues including the conjunctiva [
4], the eyelids [
5], the extrinsic ocular muscles [
6] or even the temporal artery [
7,
8] (manifestations which resemble Horton disease). However, these ophthalmic manifestations are rare and probably underdiagnosed. In a recent review of 68 cases of AL amyloidosis who received a complete ophthalmic examination, Reynold et al. [
9] identified eight cases with ocular involvement but only one with specific fundus abnormalities. Here, we report a rare case of AL amyloidosis diagnosed secondary to progressive decreased vision in relation with chorioretinal alterations, as imaged with fundus autofluorescence and Spectral domain-Optical coherence tomography (SD-OCT).
