Liquid-liquid interchange effective in post-vitrectomy bleeding
GUADALAJARA, Mexico — Treating post-vitrectomy hemorrhage using liquid-liquid interchange results in immediate elimination of blood from the vitreous cavity, according to a retinal specialist speaking here.
Miguel Angel Carvajal Quiñónez, MD, and colleagues evaluated the technique as an alternative to gas-liquid interchange. Their observational study involved 21 patients with diabetic retinopathy, most of whom had type 2 diabetes. Surgeons had treated all patients with complete panretinal photocoagulation, but patients developed vitreous hemorrhage within 6 weeks after vitrectomy, which continued for an average of 3 weeks.
Dr. Carvajal Quiñónez presented the results at the Mexican Congress of Ophthalmology.
The researchers found a 76% success rate, with blood immediately clearing from the vitreous cavity in 94% of patients and clearing by 1 week postoperatively in the remaining 6%, Dr. Carvajal Quiñónez said.
“Liquid-liquid interchange offers good results, saves regression as it can be done in consultation, and it allows immediate monitoring of the fundus of the eye,” he said.
