Purpose: To investigate whether diurnal fluctuation in intraocular pressure (IOP) can influence the result of the correlations between IOP-related factors and progression of normal tension glaucoma (NTG).
Methods: Glaucoma progression was defined as visual field (VF) progression and changes in the optic disc and/or retinal nerve fiber layer (RNFL). Two different methods were used to evaluate the impact of the diurnal fluctuation in IOP.
Purpose: We explored the performance of and pressure elevation caused by small-diameter microtubes used to reduce overfiltration.
Methods: Using a syringe pump-driven constant-flow setting (2 µL/min), pressures were measured for polytetrafluoroethylene (PTFE) microtubes 5 mm in length with inner diameters of 51, 64, and 76 µm and for polyether block amide (PEBAX) microtubes with an inner diameter of 76 µm. Experiments (using microtubes only) were initially performed in air, water, and enucleated pig eyes and were repeated under the same conditions using intraluminal 9/0 nylon stents.
Background: The aim was to evaluate changes in choroidal thickness, intraocular pressure (IOP) and other parameters of optical coherence tomography, such as central foveal thickness (CFT), macular volume, peripapillary retinal nerve fibre layer (RNFL) thickness after haemodialysis (HD).
Methods: Thirty-four eyes of 34 chronic renal failure patients (9 eyes with diabetic patients) who underwent haemodialysis in the Dialysis Unit of Gangneung Asan Hospital were included. CFT, macular volume, peripapillary RNFL and choroidal thickness were measured before and after haemodialysis by optical coherence tomography (OCT, Spectralis; Heidelberg Engineering).
Purpose: To assess the surgical outcomes and wound healing reaction of a filtering bleb after trabeculectomy using mitomycin C-soaked biodegradable collagen matrix (ologen).
Methods: Thirty eyes, in which the intraocular pressure (IOP) could not be controlled within the proper range by medication or laser treatment, were targeted in this study. After trabeculectomy with mitomycin C (0.
Purpose: To evaluate the long-term effect of Ginkgo biloba extract (GBE) on progression of visual field (VF) defects in patients with normal tension glaucoma (NTG).
Methods: Forty-two eyes of 42 patients with treated NTG who received 80 mg GBE 2 times daily and who had at least 5 VF tests using the Humphrey Visual Field Analyzer for more than a 4-year period before and after GBE treatment were evaluated in this retrospective study. We evaluated the change of progression rate using mean deviation (MD), pattern standard deviation (PSD), and visual field index (VFI) after GBE treatment.
Purpose: To evaluate the influence of the extent of myopia on the progression rate of normal-tension glaucoma (NTG).
Design: Retrospective, observational case series.
Methods: One hundred forty-three eyes of 143 patients with NTG who were treated from 1994 through 2006 and followed up with standard automated perimetry were evaluated in this study.
