BACKGROUND A congenital nasolacrimal duct obstruction (CNLDO) is a relatively common disease in infants. We evaluated the results of probing three patients with CNLDO, under direct view, with a dacryoendoscope. METHODS Three cases of CNLDO were examined and treated by probing with a dacryoendoscope, under intravenous anesthesia. The diameter of the(More)
PURPOSE To describe an infrared gonioscopy system designed to observe the anterior chamber angle under natural mydriasis in a completely darkened room. METHODS An infrared light filter was used to modify the light source of the slit-lamp microscope. A television monitor connected to a CCD monochrome camera was used to indirectly observe the angle.

In vitro and in vivo experiments have shown that topical rebamipide will increase the number of goblet cells in the bulbar conjunctiva. The purpose of this study was to determine whether topical rebamipide will enhance the recovery of conjunctival goblet cells that were damaged during vitrectomy. Forty patients who underwent vitrectomy surgery were studied.(More)
PURPOSE To evaluate and compare the findings and changes of the anterior chamber angle configuration with indentation ultrasound biomicroscopy (UBM) gonioscopy in relative pupillary block (RPB), peripheral anterior synechia (PAS), and plateau iris configuration (PIC). METHODS This study included 73 eyes of 52 patients with RPB (n = 26), PAS (n = 21), or(More)
To investigate the effects on intraocular pressure (IOP) and the occurrence of adverse events upon switching directly to latanoprost monotherapy from multiple drug therapy, including a β-antagonist, for glaucomatous eyes. Patients with primary open-angle glaucoma or ocular hypertension and receiving long-term therapy with two or three topical ocular(More)
PURPOSE To examine the presence of supraciliochoroidal fluid (SCF) by ultrasound biomicroscopy in posttrabeculectomy eyes that show good intraocular pressure (IOP) control despite the absence of an obvious filtering bleb. PATIENTS AND METHODS Eyes were selected retrospectively according to the following criteria: IOP < 15 mm Hg, no antiglaucoma(More)
PURPOSE To report the histopathological findings in a case of severe Acanthamoeba sclerokeratitis (ASK). PATIENT AND METHODS A 46-year-old patient was referred to the Department of Ophthalmology of Mie University Hospital because of a severe corneal ulcer of the right eye of 6 months' duration. Our initial examination showed a ring-shaped corneal opacity(More)
PURPOSE To investigate changes in anterior chamber angle configuration with indentation ultrasound biomicroscopy gonioscopy of relative pupillary block (RPB). DESIGN Cross-sectional study. METHODS This study included 26 eyes of 26 patients with RPB. We determined angle opening distance 500 and angle recess area using indentation ultrasound biomicroscopy(More)
We report the use of an indocyanine green (ICG) injection during the safe removal of an overhanging filtering bleb after trabeculectomy. A 63-year-old man with a history of trabeculectomy 5 years previously in his left eye complained of foreign body sensation in this eye and decreased vision from induced astigmatism. Slit-lamp examination revealed an(More)
PURPOSE To compare the ocular hypotensive effect and safety of brinzolamide and timolol added to latanoprost monotherapy. METHODS In prospective randomized fashion, we evaluated the ocular hypotensive effect and safety of brinzolamide or timolol in 1 eye of 32 patients with primary open-angle glaucoma, normal-tension glaucoma, or ocular hypertension who(More)
