Summary

Ocular trauma is one of the leading causes of blindness worldwide, often resulting in severe visual impairment or even loss of vision after injury.

Although after powerful surgical treatment, there are still some patients whose visual function is difficult to improve, and the patients with eye trauma lack effective vision rehabilitation therapy.Therefore, the research on visual function rehabilitation of patients with ocular trauma needs to be further carried out . Perceptual learning is based on cortical remodeling, repetitive visual task training. This training is to perform a series of repetitive visual tasks through the Gabor patch, simulating the receptive field structure of simple cells in the primary visual cortex (V1 area), "awakening visual cells", and improving the visual processing ability of the cerebral cortex. Compared with the traditional vision rehabilitation therapy, perceptual learning optimizes the visual quality at the visual center level. It is an innovative therapy, having the potential to solve the visual function of patients with eye trauma. This study intends to explore new visual rehabilitation methods for patients with ocular trauma, and explore the changes in visual cortical function and area of patients after perceptual training.

Conditions

  • Eye Injuries

Interventions

DEVICE

Perceptual Learning

Perceptual training is carried out at home once a day, and the viewing distance of the patients from the display screen is uniformly 1.5m, 30 minutes each time, for three months, and they return to the hospital for re-examination of ophthalmology at the 3rd months after the training. When using the perceptual training program for the first time, the training program will adjust the size of the Gabor spot according to the size of the user's computer, and prompt the patient to adjust the brightness of the computer screen to unify the Gabor spot parameters of each user and ensure the consistency of the spot stimulation information received by each user.
