Research progress of visual perception training on postoperative reconstruction of binocular vision in patients with intermittent exotropia / 国际眼科杂志(Guoji Yanke Zazhi)

Intermittent exotropia(IXT)is a common ophthalmic disease with high incidence, variable deviation, and varying degrees of impaired binocular visual function. The defect of binocular visual function is related to the changes of visual cortex. IXT involves the functional changes of many brain regions, including the cortical areas related to binocular fusion. After correcting the eye position, the abnormal changes of cerebral cortex still exist in some patients with IXT, and the recovery of binocular vision is still difficult. In order to solve these problems, visual perception training is gradually applied to the postoperative reconstruction of binocular visual function in patients with IXT. Visual perception training repairs the visual cortex from the brain level, improving the ability of the visual cortex to process information by constantly stimulating the visual center, thus repairing the visual central function, so that patients can obtain good binocular visual function, stabilize the eye position and reduce recurrence. This article reviews the mechanism of binocular visual impairment and the role of visual perception training in the treatment of IXT. It is hoped to provide more evidence for visual perception training to reconstruct postoperative binocular visual function and reduce the recurrence rate in patients with IXT.

A review on inflammation cytokines in pathogenesis of keratoconus / 国际眼科杂志(Guoji Yanke Zazhi)

@#Keratoconus(KC)is a progressive corneal thinning disease which can cause the conical appearance, scar growth and vision loss <i>via</i> corneal ectasia. Various factors were demonstrated to be related to its etiology, including the genetic factors and the environmental factors(<i>i.e.</i> the friction of eyelids and eyeball, the friction of contact lens and eyeball and the UV irradiation). In addition to the genetic and environmental factors, the inflammation cytokines has been reported as another key factor to the pathogenesis of keratoconus, thus received more attention recently. This paper then reviews the recent advances on the effect of inflammation cytokines on pathogenesis of keratoconus. The motivation of this work is to provide important guidance and thoughts for the treatment of keratoconus.
