Severe intraocular hemorrhage is a rare complication of cataract surgery due to the recent generalization of minimal-incision cataract surgery. 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.

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 from the posterior fundus, and it was extremely difficult to achieve hemostasis during the initial surgery. At 7 days after the initial surgery, PPVs were performed under general anesthesia. Bleeding significantly decreased in the second surgery compared to the first. The bleeding probably originated from the central retinal artery on the optic disc; hemostasis was obtained by coagulation of the bleeding site with intraocular diathermy. After the second surgery, there was no exacerbation of bleeding and the patient's condition was stable. However, the patient's visual acuity showed no light perception after the second surgery.

Massive intraocular hemorrhage may occur from the central retinal artery after undergoing cataract surgery. In such cases, surgery with general anesthesia with a lower maintained blood pressure (instead of surgery under local anesthesia) should be recommended, considering the possibility of difficult hemostasis in the event of bleeding from the retinal artery.
