Description
Euido Song and Do Young Park report two cases of massive suprachoroidal hemorrhage after needling bleb revision in vitrectomized eyes, a 2026 warning about a procedure often seen as safe outpatient care. Bleeding beneath the choroid threatens vision after glaucoma filtering surgery. Needling releases scar tissue around the drainage bleb blindly, so outflow cannot always be controlled. Both patients had prior vitrectomy and cataract surgery, leaving eyes vulnerable to sudden pressure drops.
An eighty-two-year-old man developed pain, hand-motion vision, and very low pressure the day after needling. He required two drainage operations and later retinal detachment surgery, ending with modest vision recovery. A fifty-year-old man lost vision after coughing the night of needling, declined drainage, and recovered slowly over three months with conservative care to finger-counting vision.
