To demonstrate the usefulness of anterior segment optical coherence tomography (OCT) to identify the supraciliary space easily.
Anterior segment OCT (Visante® Optical Coherence Tomography, Carl Zeiss Meditec Inc.,Dublin, CA, USA) was performed in 10 eyes of 7 patients suspected of supraciliary effusion or cyclodialysis cleft. At the time of OCT, The eyeball was moved clockwise, and the estimating line was adjusted to include the 1/3 cornea and 2/3 sclera on the basis of the limbus of the cornea and measured perpendicular to the limbus. And included more than two directions. When the cyclodialysis cleft was suspected, the range of 12 hours was measured at intervals of one hour to determine the range.
After argon laser peripheral iridoplasty (ALPI), intraocular pressure was adjusted to less than 10 mmHg, but supracilliary effusion was observed in 2 eyes of 2 patients with phacomorphic glaucoma. In one eyes with cyclodialysis cleft, the extent and effusion were clearly observed. In 3 eyes of 2 patients with secondary glaucoma due to peudoexfoliative syndrome or uveitis, intraocular pressure decreaed below 10 mmHg and supraciliary effusion was observed after use of glaucoma eye drops. And these supraciliary effusions improved as the intraocular pressure normalized after medication adjustment. Also secondary myopia and ocular hypertension associated with supraciliary effusion occurred in 4 eyes of 2 patients due to drugs side effect(Dorzolamide or Phendimetrazine). These side effects improved after discontinuation of the drugs and supraciliary effusion disappeared.
On the Visante®, the contour of the ciliary body was not clear, but supraciliary effusion and cyclodialysis cleft were easily detected. Unlike UBM, which was used to observe the peripheral structures of the ciliary body, Visante® allows us to quickly and easily observe the actual supraciliary space non-invasively without contact with the eye.
