To investigate relationship between laser flare photometry values and anatomic outcome of rhegmatogenous retinal detachment surgery.
Sixty patients with unilateral rhegmatogenous retinal detachment were included in the study. Thirty nine were treated with scleral buckling, 16 with pars plana vitrectomy, and 5 with pneumatic retinopexy. All patients were examined preoperatively, and 1 day, 1 week, 2 weeks, 1 month, and 3 months after surgery. The anterior chamber inflammatory activity was evaluated using the laser flare photometry (Kowa FM-500; Kowa Company, Ltd, Tokyo, Japan) before and three months after surgery. The results are expressed in photon counts per millisecond (ph/ms).
Mean preoperative flare was 34.25 +/- 55.33 ph/ms. Flare values increased according to the extent of retinal attachment (one quadrant = 20.3 ph/ms; four quadrants = 59.8 ph/ms (p=0.28)). Three months after surgery, mean aqueous flare in patients with complete retinal attachment (N=49) was 12.8 ph/ms versus 80.7 ph/ms in patients with persistent retinal detachment (N=11) (p=0.0001). No statistically significant difference was found between the different treatment procedures.
Our results show that the breakdown of the blood-ocular barrier as determined by aqueous flare is associated with increased risk for failure of retinal detachment surgery.
