Summary

The goal of this clinical trial is to learn if visual restoration therapy (VRT) (a type of treatment that aims to improve vision) works to the visual rehabilitation of patients with visual field defects. It will also learn about the safety of VRT. The main questions it aims to answer are:

* Can visual reconstruction therapy help expand the visual field in patients with visual field defects?
* What medical problems do patients with visual field defects experience during the procedure of VRT? Researchers will look at how patients with visual field defects who use a visual aid in combination with VRT and those who use a visual aid only, compare the visual field expansion at three months to see how well visual reconstruction therapy works.

Participants will:

* will undergo a specialized visual function assessment and be provided with a pair of appropriate vision aids.
* Visit the clinic at one month and three months after enrolment for review of visual function and completion of a Chinese-version Low Vision Quality of Life (CLVQOL) questionnaire.
* Participants receiving VRT will additionally undergo 30 minutes of VRT three times per week for 3 months.
* Keep a diary for their symptoms and severity and frequency of occurrence during treatment.
