Objectives

Narrative objectives1


The VEGF concentration in the vitreous humor of the patient who enforces vitreous surgery to multiplication diabetic retinopathy is measured, and eye internal-ordering ON of the Bevacizumab (AvastinOR) which is a monoclonal antibody to VEGF is carried out to the patient who was 1,000 pg/more than ml.
The prevention method of postoperative vitreous hemorrhage is established by measuring the frequency of postoperative complications with the conventional postoperative progress about the curative effect.

Interventions/Control_1

The VEGF concentration in vitreous humor carries out intravitreal administration of AvastinOR by visitors to the case which was 1,000 pg(s)/ml.
Under clean, one vial (100 mg/four ml) of AvastinOR is subdivided into a vial, it saves it 0.4 ml at a time, and necessary quantity is taken and used for a one patient from this one subdivided vial.
The circumference of an eye is disinfected enough in Isodine before injection, and applying-eyewash anesthesia is performed.
Then, 1.25 mg/0.05 ml of AvastinOR is taken to syringe, and it pours in into a vitreous body using 30G stitch.
