Let this be lattice? Dendritiform erosion in lattice dystrophy type I, a source of confusion
Lattice dystrophy type I usually presents with symptoms of recurrent erosions. As these erosions frequently follow the branching pattern of the underlying lattice network, they may mimic dendritic herpetic keratitis. This photo-essay shows the difference between a dendritiform erosion in lattice dystrophy type I and a genuine dendritic ulcer.
Lattice dystrophy type I
Corneal involvement in lattice dystrophy type I is usually bilateral and symmetric. In the early stages, the lesions can appear as irregular, thin branching refractile lines and/or whitish, ovoid dots in the anterior axial stroma with clear intervening stroma. The lines start centrally and increase in size and number with time. They extend to the periphery and involve both the deeper and the superficial stromal tissue. The typical lattice filaments are radially oriented and...
