PNEUMATIC WITHOUT PEXY: A CASE REPORT OF A RETINAL DETACHMENT REPAIR

Purpose:
To present a case of pneumatic retinal detachment repair that did not require retinal pexy.
Methods:
Report of a case and review of the literature.
Results:
Pneumatic retinopexy was performed with a plan for photocoagulation of the retinal tear once the retina was reattached. During postoperative evaluation, the superotemporal retinal tear had operculated and the retina was reattached. No laser or cryopexy was performed, and the retina remained attached during long-term follow-up.
Discussion:
Addressing traction on the retina and intraocular microcurrents that allow subretinal fluid accumulation is the core principle of detachment repair; if the traction is released, pexy may not be necessary.
