Abstract

Female monozygotic twins aged 54 years discordant for myopia are reported. One twin presented with bilateral high myopia (right eye = −6.00/+0.50 × 5°, left eye = −6.00/+0.50 × 45°) and her identical twin had no significant refractive error (right eye = −0.50/plano, left eye = −0.50/+0.75 × 40°). An explanation for the striking refractive discordance seen in this case report is yet to be determined.
