Anterior segment ischemia after segmental episcleral buckling and cryopexy.
A 63-year-old man with a one-quadrant retinal detachment developed anterior segment ischemia after an operation that included the use of cryopexy, release of subretinal fluid, and segmental episcleral buckling without detachment of the extraocular muscles. A compromised cardiovascular condition of long duration and an episode of transient hypotension immediately preceding operation were factors in the pathogenesis of the ischemia. Although the anterior segment changes were moderately severe, recovery of vision ultimately was excellent.
