A 22-year-old man presented with progressive diminution of vision in the left eye since early childhood. Visual acuity was 20/25 OD and finger counting close to face OS. Slitlamp examination revealed scattered, prominent midperipheral iris strands in both eyes. In addition, the left eye also showed a white circular band attached to the prominent iris strands along 3 quadrants (Figure, A, white arrowhead). Gonioscopy revealed anteriorly inserted iris, with prominent iris processes in both eyes (Figure, B). Therefore, a diagnosis of presumed posteriorly luxated Schwalbe line with secondary glaucoma (intraocular pressure, 24 mm Hg OD and 28 mm Hg OS) was made and further treatment planned.
