Assessment of Iris Surface Features and Their Relationship with Iris Thickness in Asian Eyes – Corrected Proof

Purpose: To assess iris surface features in Asian eyes and examine their associations with iris thickness measured by anterior segment optical coherence tomography (AS OCT).Design: Cross-sectional study.Participants: We recruited 250 subjects from the Singapore Malay Eye Study.Methods: We obtained standardized slit-lamp photographs and developed a grading system assessing iris crypts (by number and size), furrows (by number and circumferential extent), and color (higher grade denoting darker iris). Vertical and horizontal cross-sections of the anterior chamber were imaged using AS OCT. Intragrader and intergrader agreements in the grading of iris surface were assessed by weighted κ (κw) statistic. Associations of the (Read more...)
