Abstract:
PURPOSE:To study the prevalence of ciliochoroidal effusion (CE) after prophylactic laser iridotomy (LI). METHODS:An ultrasound biomicroscope (UBM) examination was performed before, 2, and 24 hours after LI to investigate the changes in supraciliary-choroidal space after LI in circumference of 38 eyes in 23 chronic primary angle-closure patients. Subjects were divided randomly into two groups based on LI settings: 21 eyes by argon laser (Ar-LI group) and argon combined with yttrium-aluminum-garnet (YAG) laser in 17 eyes (Ar-YAG-LI group). Ciliochoroidal effusion was observed predominantly in the inferior sector (12 of 12 eyes, 100%) and rare in nasal part of the eyes (4 of 12 eyes, 33%). Ciliochoroidal effusion appeared more often in the Ar-LI group (10 eyes, 52%) than in the Ar-YAG-LI group (2 eyes, 12%). All CE disappeared 7 days after by UBM observation. CONCLUSIONS:Subclinical CE observed by UBM frequently occurs after LI.
