Purpose: To understand better the relationship between the macular ganglion cell complex (mGCC) thickness and visual field sensitivity assessed by frequency-doubling technology (FDT) perimetry in the standard automated perimetry (SAP) normal hemifields of glaucomatous eyes, a model of preperimetric stage of glaucoma.
Patients And Methods: Thirty-four eyes of 34 patients with glaucomatous visual field defects restricted to the superior or inferior hemifield were included. Patients underwent the mGCC and circumpapillary retinal nerve fiber layer (cpRNFL) thickness measurements using spectral domain optical coherence tomography and the FDT testing with N-30 full-threshold protocol.
Purpose: To study diagnostic performances of circle- and grid-wise analyses of peripapillary retinal nerve fiber layer thickness (RNFLT) using spectral domain optical coherence tomography (SD-OCT) in early-stage glaucoma.
Methods: Eighty-nine open-angle glaucoma (OAG) eyes (mean deviation: 2.5 ± 1.
Purpose: To investigate the influence of glaucoma and myopia on the cross-sectional configuration of the β-zone of peripapillary atrophy (PPA-β) using spectral-domain optical coherence tomography (SD-OCT).
Methods: Cross-sectional B-scan images of PPA-β obtained with SD-OCT were evaluated in 100 eyes of 100 consecutive patients with POAG, regardless of intraocular pressure level, and in 100 eyes of 100 normal subjects. PPA bed configurations were classified, and associated factors were studied with multivariate analysis.
Objectives: To evaluate the peripapillary distribution of retinal nerve fiber layer thickness (RNFLT) in normal eyes using spectral-domain optical coherence tomography and to study potentially related factors.
Methods: In 7 institutes in Japan, RNFLT in 7 concentric peripapillary circles with diameters ranging from 2.2 to 4.
Aims: To characterise the optic nerve head (ONH) configurations of superior segmental optic hypoplasia (SSOH) using a spectral-domain optical coherence tomography (SD-OCT).
Methods: Horizontal cross-sectional images of the ONH were obtained by a SD-OCT in 20 eyes of 14 patients with clinically typical SSOH and 20 age- and refraction-matched normal eyes.
Results: Extension of retinal pigment epithelium (RPE) over the disc margin was observed in 20 eyes (100%) with SSOH and eight (40%) control eyes (p<0.
Purpose: To evaluate the cross-sectional configurations of peripapillary atrophy (PPA)-alpha and -beta in ophthalmologically normal subjects using spectral domain-optical coherence tomography (SD-OCT).
Methods: One hundred twenty normal subjects had a complete ophthalmic examination including axial length measurement, standard automated perimetry, fundus imaging with photography, and SD-OCT (3D OCT-1000; Topcon Inc., Tokyo, Japan).

Purpose: To evaluate the clinical features of nosocomial epidemic keratoconjunctivitis(EKC) occurring in the ophthalmology ward of Sapporo Medical University Hospital and to devise preventive measures for it.
Materials And Methods: We studied the symptoms and clinical course of 2 patients who had EKC and 16 patients who had EKC caused by nosocomial infections in our hospital. We attempted to detect adenovirus antigen and viral DNA from conjunctival swabs and also to isolate the virus.
