| Popis: | During blunt ocular trauma, the anteroposterior compressive forces confronted lead to consequent equatorial expansion of the globe. This may result in ciliary body trauma, typically manifesting as angle recession or cyclodialysis. The authors hypothesize that a likely asymmetric contraction between the longitudinal and circular ciliary fibers, and an intrinsic weak "oblique buffer zone" creates a plane of separation between the 2, resulting in angle recession. When stronger forces are met with, the equatorial expansion of the sclera may outperform the ability of the ciliary body to follow it, and the taut longitudinal ciliary fibers may subsequently disinsert from the scleral spur causing cyclodialysis. In addition to this, the routinely thought dismembering aqueous jets directed toward the angle may also accentuate ciliary body trauma. Therefore, the vivid distractive external forces along with the complex ciliary muscle anatomy and differential functionality may play a crucial role in causation of post-traumatic angle recession and cyclodialysis. |
