PURPOSE To describe recent technological additions to the NIDEK CXIII and Quest excimer lasers. METHODS A summary article with data from previous published studies outlining the benefits of newer technology. RESULTS The addition of a 1-kHz infrared eye tracker decreased the spread of laser spot placement from a mean of 228.79 microm without a tracker to 38.47 microm with the eye tracker. Th...

Purpose: To investigate the clinical significance of ocular torsion in children by analyzing associated ophthalmic diseases.Methods: Fundus images were used to detect one or both eyes 83 aged 2-12 years at a pediatric ophthalmology clinic. In cases with torsion, diseases, including strabismus, amblyopia, and refractive errors, investigated.Results: Among patients, 59 (71.2%) 45 (54.2%) had stra...

In a previous study dated back to 2001, a small sample of cyclotropic patients were found to be affected by abnormal spatial relationship perception (aspect ratio judgment) with increased discrimination threshold of elliptical targets oriented along the horizontal axis. The angular amount of incyclodeviation correlated significantly with the discrimination threshold along the horizontal axis. O...

When binocular vision is prevented with monocular occlusion, the two eyes assume a position of rest related to the combination of underlying tonic innervation of the oculomotor system, cross-coupled accommodative-vergence input and vergence responses to perceptual cues for spatial location relative to the head. When the latter two are controlled, the covered eye has been shown in the majority o...
