ABSTRACT
PURPOSE: To detect the presence of supraciliochoroidal fluid (SCF) by ultrasound biomicroscopy (UBM) at an early stage after trabeculectomy. METHODS: Trabeculectomy with mitomycin C was performed on 14 patients (15 eyes) with medically uncontrolled glaucoma. The ciliary bodies were observed using UBM testing, which was conducted preoperatively and within 2 weeks after the procedure. RESULTS: SCF was detected postoperatively in 6 eyes. One eye also had choroidal detachment (CD), as seen with an indirect ophthalmoscope; and 5 eyes (33%) had SCF without intraocular inflammatory clinical signs, postoperative changes of the anterior chamber depth, or obvious CD. The SCF in 4 eyes disappeared within 4 weeks after the trabeculectomy. The intraocular pressure (IOP) was 6.4 +/- 3.4 mm Hg (mean +/- SD) when SCF was detected and it rose to 13.2 +/- 7.2 mm Hg when the SCF disappeared. The IOP was 11.4 +/- 4.0 mm Hg in the eyes without SCF, which was significantly higher than that seen in the eyes with SCF. CONCLUSIONS: At an early stage after trabeculectomy, SCF without subclinical CD was detected in some cases by UBM. Compared with the reported frequency of SCF after 3 or 6 months, our study revealed that SCF was present more frequently at an early stage after trabeculectomy. Our results may indicate that the presence of SCF is related to the early low IOP after trabeculectomy and that the disappearance of SCF induces the elevation of IOP.

MAI or MIRAgel is a hydrogel developed as a scleral buckling material. We identified upper lid masses and a limitation of supraduction in the left eye of a patient who was associated with extrusion and fragmentation of the MIRAgel episcleral exoplant 11 years after scleral buckling surgery. The material could not be removed completely because of fragmentation. Fragmentation and extrusion of MIRAgel may be rare, but periodic long-term follow-up examinations should be performed after this product has been used.

We report a 26-year-old man with Coats' disease associated with premacular fibrosis. As an initial treatment, the peripheral exduative area was treated with argon laser photocoagulation. Six weeks later, the premacular fibrosis was peeled off and the posterior vitreous membrane was also detached. The patient's visual acuity improved to 20/20. We also observed a change of the vitreous component before and after the treatment that was similar to posterior vitreous detachment (PVD). This is the first reported case in which a distinct vitreous change was observed after premacular fibrosis peeling in Coat's disease.
