Visual field defects: Early in retinitis pigmentosa, there may be ring-shaped dark spots in the visual field, and then the ring-shaped dark spots will slowly expand to the center and periphery to become a tubular visual field, which will make the peripheral visual field shrink, resulting in visual field defects in patients. 3. Loss of vision: Retinitis pigmentosa center vision is normal or close to normal in the early stage, with the development of the disease, the field of vision is gradually defective, and then the patient’s vision gradually diminishes until blindness.
