We report a case of a massive intraocular hemorrhage that probably originated from the central retinal artery after cataract surgery, in which hemostasis was difficult to achieve during vitrectomy.<h4>Case presentation</h4>An 86-year-old woman was referred to our department for intraocular lens (IOL) dislocation after undergoing cataract surgery. Massive intraocular hemorrhage was observed during the initial visit to our department. She underwent pars plana vitrectomy (PPV) and IOL repositioning under local anesthesia. However, the hemorrhage could not be removed completely because of continued massive intraoperative bleeding froBMC ophthalmologyMassive intraocular hemorrhage, presumably from the central retinal artery after cataract surgery, and difficult hemostasis during vitrectomy: a case report.PMC935884819K18837Ishii KNakagawa SfalseMassive intraocular hemorrhage, presumably from the central retinal artery after cataract surgery, and difficult hemostasis during vitrectomy: a case report.<h4>Background</h4>Severe intraocular hemorrhage is a rare complication of cataract surgery due to the recent generalization of minimal-incision cataract surgery.
