Summary

To explore a quantitative glaucoma evaluation tool of glaucoma through the dynamic evaluation of reading ability based on logarithmic Chinese reading acuity chart (C-READ), and investigate its feasibility.

Detailed description

Glaucoma is the most common cause of irreversible blindness in the world, and it's marked by the gradual loss of retinal ganglion cells and their optic nerve fibres. Early detection and treatment can successfully prevent the disease's development and prevent blindness. Glaucoma sufferers' near visual qualities, particularly their ability to read, might be compromised. Patients can, however, regain some comfortable reading capacity following glaucoma therapy. The logarithmic Chinese reading acuity chart (C-READ) can be beneficial as a tool for functional vision evaluation, and there is rising clinical interest in this well-standardized, calibrated reading chart. Reading chart standards that allow for equal assessment of reading factors such as acuity and speed are currently lacking. The C-READ approach as a judge of glaucoma patients' status lacks theoretical support, and functional visual evaluation tools are still in their infancy. Therefore, we want to complete these tasks: 1) develop a dynamic analytic system and improve the evaluation criteria for the C-READ testing procedure; 2) confirm the usefulness of C-READ for early glaucoma screening through clinical studies. C-READ will provide a reliable and cost-effective screening technique that is convenient, affordable, and noninvasive.
