Diagnostic Considerations

Ring melanoma of ciliary body [40]

Elevated episcleral venous pressure/carotid cavernous fistula

Iridocorneal endothelial (ICE) syndrome

Uveitis-glaucoma-hyphema (UGH) syndrome

Angle recession refers to a tear between the circular and longitudinal fibers of the ciliary body. Cyclodialysis is defined as a detachment of the ciliary body from its insertion at the scleral spur. Iridodialysis is separation of the iris root from its attachment to the anterior ciliary body. By comparison, iridoschisis refers to splitting of layers of iris stroma. All of these conditions are sequelae of blunt ocular trauma, and any of these conditions may coexist. Laboratory studies have indicated that iridodialysis and cyclodialysis occur at higher blunt impact energies compared with the relatively lower thresholds resulting in angle recession. [6]
