[Aqueous protein concentration after vitrectomy for diabetic retinopathy].
The protein concentration in the aqueous humor in 46 eyes with proliferative diabetic retinopathy was quantitated before and after vitrectomy. Before surgery, the protein value as measured by a laser flare-cell meter was 5 times that in normal control eyes. The value was elevated on day 3 after surgery and gradually decreased to reach the preoperative value 1 month after surgery. The postoperative protein value significantly increased in accordance with the complexity of surgical maneuvers until day 17 when the 46 eyes were classified into 3 groups: simple-maneuver group (12 eyes), membrane delamination group (18 eyes) and silicone oil group (16 eyes). The time course of aqueous protein concentration in the simple-maneuver group was similar to that after vitrectomy for vitreous hemorrhage in 8 eyes with prior branch retinal vein occlusion. The observed increase in aqueous protein after vitrectomy seemed to be transferred from vitreous cavity to anterior chamber.
