Abstract

Presbyopia, a decline in near vision due to aging, is primarily linked to changes in the crystalline lens. However, the ciliary muscle also contributes to this condition. Previous OCT studies focused on measuring ciliary muscle thickness at static accommodative states to understand its age-related functional response. Yet, this approach falls short in capturing the centripetal movement of the ciliary muscle towards the lens, which anatomically represents its functional response better than thickness changes. In this study, we introduce a novel method using statistical shape analysis, enabling dynamic assessment of the ciliary muscle's centripetal movement during accommodation through transscleral OCT images. This approach serves as a novel tool to explore the ciliary muscle's role in presbyopia development and optimize accommodating implant design.
