THE INFLUENCE OF STRABISMUS SURGERY ON THE BLOOD-AQUEOUS BARRIER - TYNDALLOMETRY CASE-STUDIES IN PATIENTS WITH RISK-FACTORS

We present tyndallometry as a method for investigation of sub-clinical changes in anterior-chamber flare in patients with risk factors regar ding anterior-segment ischemia after squint surgery. The cases of six adult patients who underwent surgery on the vertical recti and who had additional risk either because of dysthyroid orbitopathy or because o f transpositions carried out on the recti are presented. In one case a transient subclinical increase in the flare value was observed. This noninvasive method seems suitable for the provision of further informa tion on the pathophysiology of anterior-segment ischemia and for monit oring of patients at special risk postoperatively such thar early trea tment can be started if necessary. Additionally, early detection of no nischemic intraocular inflammation in the postoperative course is rend ered possible by this examination.
