Fig. 2From: Fourier domain optical coherence tomography to assess the iridocorneal angle and correlation study in a large Caucasian population a Relationship between trabecular-iris angle (TIA) and age. Angle width measurements diminished from 18 years to 56–60 years, and stabilized thereafter. b Relationship between TIA and spherical refractive error. Mean trabecular-iris angle (TIA) was stable over the range < -9 to -3 diopters, point from which it was decreasing progressively toward hyperopiaBack to article page
