Lattice corneal dystrophy is an autosomal dominant condition caused by a mutation in the TGFBI gene. The condition results in amyloid deposits which classically appear as refractile, branching lines in the anterior corneal stroma. The patients may also have subepithelial ovoid white dots and diffuse anterior stromal haze. These findings begin centrally at a young age and spread outward over time. The above photos show the eyes of two different patients with varying presentations of the disease.
A 55-year-old female presented with foreign body sensation in both eyes. She has a family history significant for lattice corneal dystrophy in her father and paternal grandmother. On exam, there were prominent refractile lines in the anterior corneal stroma with a branching pattern consistent with lattice corneal dystrophy.
