Summary
Haemorrhagic choroidal detachment (HCD) is a rare but serious complication during eye surgery. This case suggests localized HCD may result from pressure changes during encircling band placement after fluid-air exchange.
Area of Science:
- Ophthalmology
- Surgical Complications
- Retinal Surgery
Background:
- Haemorrhagic choroidal detachment (HCD) is a rare but severe intraoperative complication in ophthalmic surgery.
- Acute hypotony is a known risk factor, but pathogenesis of localized HCD is not fully understood.
Observation:
- A case of localized HCD occurred during pars plana vitrectomy for rhegmatogenous retinal detachment.
- The event followed fluid-air exchange and the final tie of an encircling element.
Findings:
- The authors propose that localized HCD in this instance was caused by compressive and decompressing forces.
- These forces were exerted during the tightening of the encircling element after fluid-air exchange.
Implications:
- Understanding this specific mechanism may help prevent localized HCD during similar retinal detachment surgeries.
- This highlights the importance of careful management of intraocular pressure and surgical maneuvers.
