Abstract
The blood-aqueous barrier (BAB) in experimentally induced anterior segment ischemia (ASI) following strabismus or retinal detachment surgery in pigmented rabbits was evaluated by laser flare photometry. Four simultaneous rectus tenotomies produced a significantly higher flare value on the 1st postoperative day. Obstruction of one or two vortex veins produced significantly high flare values on the 1st and 3rd postoperative days. Scleral buckling with interference of one vortex vein produced a higher flare value than that with buckling alone. Interference of three vortex veins by diathermy and the encircling procedure produced serious ASI. Disruption of BAB in ASI can be detected quantitatively with laser flare photometry. Introduction of prostaglandin synthetase inhibitor resulted in a significant reduction of flare values following surgery. Prostaglandin synthetase inhibitor can partly ameliorate BAB disruption.
