[Long-term study of nipradilol ophthalmic solution in patients with normal-tension glaucoma].

Purpose: We investigated the long-term clinical effects of a nipradilol ophthalmic solution on normal-tension glaucoma.

Methods: Among normal tension glaucoma patients who consulted the Nara Medical University Hospital or 2 affiliated hospitals between November 2001 and August 2002, we prospectively examined intraocular pressure-decreasing effects, the deterioration of visual field defects, and the appearance of side effects in 46 patients who underwent single therapy with a nipradilol ophthalmic solution. We evaluated intraocular pressure at 6-month intervals.

Objective visual field evaluation using multifocal visual evoked potentials in patients with intracranial disease complicated by mental disorders.

Objectives: We investigated whether visual field defects can be objectively evaluated using multifocal visual evoked potentials (mfVEPs) in patients with intracranial disease complicated by mental disorders.

Patients And Methods: First, to determine the normal pattern of mfVEPs, recordings were performed using a VERIS Junior Science recording apparatus (Mayo, Aichi, Japan) in 40 healthy subjects. Responses from 8 sites in each subject were divided into 4 quadrants (superior and inferior temporal quadrants and superior and inferior nasal quadrants).

Usefulness of multifocal VEP in a child requiring perimetry.

We examined the reliability of multifocal visual evoked potentials for evaluating visual-field defects in a child with epilepsy and an arachnoid cyst. Multifocal visual evoked potentials were measured both when perimetry was difficult and several years later, when kinetic perimetry became possible in a child with epilepsy and homonymous hemianopia, as suggested by computed tomography of the brain. The peak latency and amplitude of response waves were used for assessment.

Impact of nuclear cataract density on postoperative refractive outcome: IOL Master versus ultrasound.

Purpose: To evaluate the effect of cataract density on the postoperative refractive outcome.

Methods: For 59 nuclear cataract eyes, the axial length was preoperatively measured by the IOL Master (Zeiss, Germany) and ultrasound (US; UD-6000, Tomey, Japan) and the cataract density by EAS-1000 (Nidek, Japan). The prediction error was used as evaluation of the accuracy of ocular biometry.

Change in dynamic visual acuity (DVA) by pupil dilation.

Objective: This study was conducted to assess dynamic visual acuity (DVA) under pupil dilation.

Background: Pupil dilation may negatively affect driving performance.

Methods: Thirty healthy young adults (mean age 29.

Effect of total higher-order aberrations on accommodation in pseudophakic eyes.

Purpose: To analyze the effect of total higher-order aberrations (HOAs) on the range of accommodation in pseudophakic eyes and the size of near-vision optotypes.

Setting: Department of Ophthalmology, Nara Medical University, Nara, Japan.

Methods: The study comprised 30 patients (44 eyes) who were diagnosed with cataract at Nara University of Medical Science Hospital and Municipal Oyodo Hospital.

Pattern-reversal visual evoked potentials in patients with human T-lymphotropic virus type 1 uveitis.

Purpose: The purpose of this study was to evaluate the possible injury in the optic pathway by measuring P100 peak latency of pattern-reversal visual evoked potentials (PVEPs) in patients with human T-lymphotropic virus type 1 uveitis (HU).

Methods: The P100 peak latency of PVEP was measured during the period without macular abnormalities observed by fluorescein angiography in 23 patients (46 eyes) with HU and 24 patients (48 eyes) with Vogt-Koyanagi-Harada disease (VKH) with a corrected visual acuity of 20/25 or more. To determine the normal upper limit of P100 peak latency, PVEPs were measured in 31 normal subjects (31 eyes).

Effect of tilt of 2 acrylic intraocular lenses on high-order aberrations.

Purpose: To investigate the high-order aberrations (HoAs) in pseudophakia between 2 foldable acrylic intraocular lenses (IOL) with differences in the tilt of IOL.

Setting: Department of Ophthalmology, Nara Medical University, Nara, Japan.

Method: Sixty-four eyes that had uncomplicated phacoemulsification and IOL implantation were assigned to 1 of 2 groups: Acryfold 60BB (HOYA [n=30 eyes]) and AcrySof MA60AC (Alcon [n=34 eyes]).

Influence of intraocular lens optical design on high-order aberrations.

Purpose: To compare differences in high-order aberrations (HOAs) between 2 intraocular lens (IOL) optical designs.

Setting: Department of Ophthalmology, Nara Medical University, Nara, Japan.

Method: Sixty eyes that had uncomplicated phacoemulsification and IOL implantation were assigned to 1 of 2 groups based on the type of IOL optical design: more posteriorly curved biconvex shape (AcrySof MA30BA, Alcon) (n=30 eyes) or more anteriorly curved biconvex shape (AcrySof MA30AC) (n=30 eyes).

A child with epilepsy in whom multifocal VEPs facilitated the objective measurement of the visual field.

Purpose: We investigated whether visual field defects can be objectively evaluated by using multifocal visual evoked potential (multifocal VEP) in children with epilepsy in whom it is difficult to measure the visual field.

Volume phase transition of bovine vitreous body in vitro and determination of its dynamics.

The phase equilibrium property and structural and dynamical properties of bovine vitreous body was studied by macroscopic observation of swelling behavior and dynamic light scattering under various conditions. It was found that the vitreous body collapses into a compact state isotropically or anisotropically depending on the external conditions. The vitreous body collapses while maintaining the shape when the pH ( View Article and Find Full Text PDF
