Measurement of intraocular pressure using the NT-4000: a new non-contact tonometer equipped with pulse synchronous measurement function.

Purpose: NT-4000 (Nidek Co. Ltd., Gamagori, Japan) is a new non-contact tonometer (NCT) equipped with pulse synchronous measurement function that can measure intraocular pressure (IOP) synchronized with the ocular pulse.

Optic disc topography as measured by confocal scanning laser ophthalmoscopy and visual field loss in Japanese patients with primary open-angle or normal-tension glaucoma.

Purpose: To determine whether differences in the optic disc topography and those in the relation between the optic disc topography and visual field indices exist between Japanese patients with primary open-angle glaucoma (POAG) and normal-tension glaucoma (NTG).

Methods: The study included consecutive Japanese patients with POAG (n = 60) or NTG (n = 60). Using the Heidelberg Retina Tomograph (HRT), we measured disc area, cup area, cup-to-disc area ratio, rim area, cup volume, rim volume, cup shape measure, and height variation contour.

[A case of acute angle-closure glaucoma secondary to annular ciliochoroidal detachment after unsutured cataract surgery].

Background: We report a patient with acute angle-closure glaucoma secondary to annular ciliochoroidal detachment after unsutured cataract surgery.

Case: An 82-year-old man was diagnosed with bilateral shallow central anterior chamber depth, flat peripheral anterior chamber, and elevated intraocular pressure. One day previously he had undergone uncomplicated unsutured cataract surgery in the right eye and eight days previously, in the left eye.

Relationship between indices of Humphrey perimetry and Frequency Doubling Technology Perimetry in glaucoma.

Purpose: To study whether the correlation between indices of Humphrey perimetry and Frequency Doubling Technology (FDT) perimetry differs in the early and later stages of glaucoma.

Methods: This study included 200 eyes of 200 patients with primary open-angle glaucoma or normal-tension glaucoma. The eyes were classified into the early and later stages by the median value (-4.

Surgical management of retinal detachment associated with myopic macular hole: anatomic and functional status of the macula.

Purpose: To evaluate the postoperative status of the macula after vitreous surgery with internal limiting membrane removal for macular hole related retinal detachment in patients with severe myopia.

Design: Interventional case series.

Methods: We prospectively examined 10 eyes with retinal detachment associated with a myopic macular hole from 10 consecutive patients, and performed pars plana vitrectomy with internal limiting membrane peeling.

Relationship between optic nerve head microcirculation and visual field loss in glaucoma.

Purpose: To study the relationship between optic nerve head blood flow velocity and visual field loss in patients with primary open-angle glaucoma (POAG) and normal tension glaucoma (NTG).

Methods: This study included 44 eyes of 44 patients with POAG and 44 eyes of 44 patients with NTG. To evaluate optic nerve head blood flow velocity, the square blur rate (SBR) was measured by means of laser speckle flowgraphy.

[A case of steroid-induced glaucoma after radial keratotomy].

Background: We report a patient who was diagnosed as having steroid-induced glaucoma after radial keratotomy(RK) and suffered from severe visual field defect.

Case: A 29-year-old man underwent RK for both eyes. After the operation, he was treated for six months with topical medication including 0.

Myopia and advanced-stage open-angle glaucoma.

Objective: To investigate the effect of myopic refraction on the central visual field in patients with advanced open-angle glaucoma (OAG).

Design: Multicenter cross-sectional study.

Participants: Three hundred thirteen OAG eyes (176 eyes of 176 primary open-angle glaucoma [POAG] patients and 137 eyes of 137 normal-tension glaucoma [NTG] patients) with clear ocular media and a mean deviation (MD) <-15 dB.

Severe hypotony after macular translocation surgery with 360-degree retinotomy.

Purpose: To report a case of severe hypotony after macular translocation with 360-degree retinotomy.

Design: Interventional case report.

Methods: A 50-year-old woman with myopic neovascular maculopathy underwent macular translocation with 360-degree retinotomy in her left eye.

[Changes in filtering bleb with laser treatment after non-penetrating trabeculectomy].

Purpose: Ultrasound biomicroscopy(UBM) was performed on filtering blebs with laser treatment including laser gonioplasty(GP), laser iridotomy(LI), and YAG laser trabeculopuncture(YLT) after non-penetrating trabeculectomy(NPT). The filtering blebs were grouped into four types, L, H, E and F, and the spaces under the scleral flap were classified into three. La, S, and N.

Specificity and sensitivity of glaucoma detection in the Japanese population using scanning laser polarimetry.

Aims: To investigate the usefulness of the scanning laser polarimeter (GDx; GDx Nerve Fiber Analyzer) for glaucoma detection in the Japanese population, and to investigate the difference in the thickness of retinal nerve fibre layer (RNFL) between normal tension glaucoma (NTG) and primary open angle glaucoma (POAG).

Methods: 69 eyes of 69 normal subjects and 115 eyes of 115 chronic open angle glaucoma patients (60 NTG and 55 POAG patients) were studied. The thickness of RNFL was measured with GDx.
