Patient's question:
Recently, I have been carefully examining the optic neuritis. I feel that my vision has declined significantly, and I can't see things clearly up close. Sometimes, for two or three days, many things appear blurry. I need to have an external eye examination, and everything is normal. The doctor said it might be optic neuritis, so he asked me what kind of detailed examination of the optic neuritis should be done and how to carefully examine neuritis.Doctor's answer:
Optic neuritis or papilledema refers to inflammation of any part of the optic nerve. Symptoms:(1) Hearing loss:
(2) Changes in visual field:
(3) Changes in the pupil: Complete hearing loss. The pupil shows no direct light reflex; severe vision impairment, the direct light reflex of the pupil becomes weak, the pupil of the diseased eye begins to constrict and then expands spontaneously, or under natural light, the pupil of the diseased eye expands, covering the diseased eye's pupil while the pupil of the healthy eye remains unchanged, known as the Hering phenomenon.
