Purpose: The pathology of Parkinson's disease (PD) is suspected to affect the retina and choroid. We investigated changes in the retina and choroid of patients with PD using optical coherence tomography.
Methods: We examined 14 patients with PD and 22 patients without PD.
Article Synopsis
- - The study aimed to train 45 school children with myopia using a visual stimulation device that created a blur stimulus while maintaining constant image size and brightness, to assess its effects on various vision metrics.
- - Over a year, 42 out of 45 children successfully completed the training, with notable improvements: the mean refraction decreased and axial length increased, indicating enhanced visual acuity.
- - Key dynamic accommodation measures improved significantly, including a reduced latency in response time, higher gain in the accommodative phase, and increased maximum speed of accommodation throughout the training period.
Introduction And Purpose: To investigate the effect of exodeviation in spatial visual attention using the illusory line motion paradigm.
Methods: The perception of visual illusion (i.e.
Purpose: Application of adequate correction of refractory errors for the treatment of asthenopia of young visual display terminal (VDT) workers was evaluated from subjective complaints and the effect on accommodation dynamics (step response) before and after 6 months.
Methods: Young VDT workers who visited the clinic because of eye strain were consecutively selected. Fifteen workers who were under-corrected for myopia and three workers who were over-corrected for myopia were treated by "adequate correction of refractory errors" with spectacles or soft contact lenses.
Effects of ocular dominance on binocular summation after monocular reading adds.
J Cataract Refract Surg
August 2005
Purpose: To investigate the relationship between ocular dominance and binocular summation with monocular reading adds.
Setting: Department of Orthoptics and Visual Science, School of Allied Health Sciences, Kitasato University, Sagamihara, Kanagawa, Japan.
Methods: Contrast sensitivities were measured by having subjects view contrast charts at spatial frequencies of 1.
Purpose: To investigate the relation between sighting and sensory eye dominance and attempt to quantitatively examine eye dominance using a balance technique based on binocular rivalry.
Methods: The durations of exclusive visibility of the dominant and nondominant eye target in binocular rivalry were measured in 14 subjects. The dominant eye was determined by using the hole-in-card test (sighting dominance).
Purpose: To elucidate the relationship between ocular dominance and patient satisfaction with monovision induced by intraocular lens implantation.
Setting: Eye Clinic, Kitasato University School of Medicine Hospital, Sagamihara, Kanagawa, Japan.
Methods: The durations of exclusive visibility of dominant- and nondominant-eye targets were measured in 16 patients with successful monovision and 4 patients with unsuccessful monovision to determine the characteristics of ocular dominance.
Repair and reconstruction of the mouse lens after perforating injury.
Jpn J Ophthalmol
September 2003
Purpose: To investigate the process of repair in the epithelial cells and the reconstruction in lens fibers of a mouse lens that has developed opacity because of a large-scale perforating injury.
Methods: Lenses of 4-week-old mice were perforated with a needle through the cornea to induce the development of traumatic cataracts. Over the period from the first day to the fifth month after injury, eyeballs were extracted progressively from the mice and changes in the epithelial cells of these lenses were observed morphologically as well as histochemically.
Two clinical cases in which ischemic optic neuropathy (ION) occurred after subarachnoid hemorrhage (SAH) are reported. Hemorrhage in the proximity of the optic chiasm was confirmed in 2 cases following rupture of an anterior communicating artery aneurysm. Optic disk atrophy with excavation and permanent visual field defect (altitudinal superior hemianopia) occurred in both cases.

Methods: Changes in corneal curvature and intraocular pressure (IOP) were measured over 24 hours in 14 young adults using corneal topography and a non-contact tonometer. In study 1, seven males and seven females (after menses) were measured.
