A possible relationship between lattice and snail track degenerations of the retina.

We studied 1,000 eyes of 500 subjects in an attempt to discover a relationship between lattice and snail track degenerations of the peripheral retina. Because of the clinical similarities between these two degeneration lesions, we suggest that snail track degeneration is either a variant of or an early stage of lattice degeneration. Long-term follow-up of eyes with snail track degeneration is essential to detect any morphologic alteration in the lesions suggesting lattice degeneration.
