Introduction
Under normal circumstances, the symptoms and manifestations of glaucoma mainly include visual field defects, eye pain, headache, eye redness or conjunctival congestion, and halos around lights (chromatopsia). If physical discomfort occurs, it is recommended to seek medical attention promptly and receive treatment under the guidance of a qualified physician. In daily life, one should avoid strenuous exercise, minimize fluctuations in intraocular pressure, and avoid eye irritation.

Generally, the symptoms and manifestations of glaucoma mainly include visual field loss, eye pain, headache, eye redness or conjunctival congestion, and halos around lights (chromatopsia). If physical discomfort occurs, timely medical consultation is recommended, and treatment should be conducted under the guidance of a qualified physician. A detailed explanation is as follows:

1. Visual Field Loss: Visual field loss caused by glaucoma results from optic nerve atrophy, which is irreversible. Patients may experience a gradual narrowing of their visual field or blind spots in certain directions.

2. Eye Pain: Patients with glaucoma may feel pain or discomfort in the eyes, typically caused by elevated intraocular pressure. Eye pain may manifest as aching or pressure in the eyeball or the eye socket, or both, and may be accompanied by other symptoms such as headache and nausea.

3. Headache: Patients with glaucoma may experience persistent or intermittent headaches, usually associated with increased intraocular pressure. Headaches may occur simultaneously with or after eye pain and may worsen as the condition progresses.

4. Eye Redness or Conjunctival Congestion: Patients with glaucoma may develop red eyes or conjunctival congestion, which may be caused by dilation and congestion of ocular blood vessels due to elevated intraocular pressure.

5. Halos Around Lights (Chromatopsia): When intraocular pressure rises abnormally in glaucoma, patients may experience halos around lights, where light sources appear to be surrounded by rainbow-like rings. Chromatopsia occurs due to abnormal refraction of light caused by changes in the distribution of fluid within the eye.

In daily life, it is important to avoid strenuous exercise to reduce intraocular pressure fluctuations and to avoid eye irritation, such as prolonged eye use, watching television, or using electronic devices, in order to alleviate eye discomfort.

Can I take Compound Paracetamol and Dextromethorphan Syrup when my temperature is 38°C?
If the body temperature is 38°C without any cold symptoms, or if the fever is caused by other conditions such as bacterial infection (e.g., pneumonia) or autoimmune diseases, or if the patient has severe underlying diseases such as liver or kidney dysfunction or glaucoma, this medication is not recommended. Taking the drug in these situations will not address the underlying cause, may mask the true condition with its active ingredients, delay diagnosis, or exacerbate the burden on pre-existing medical conditions.

Can people with depression have their pupils dilated?
Dilation primarily affects the eye, using medication to enlarge the pupil for procedures such as refraction or fundus examination. It usually does not directly influence mood or exacerbate symptoms of depression. If a patient has normal ocular structures, no glaucoma, abnormal intraocular pressure, or active inflammation, and has not recently taken medications that may affect pupillary response, routine dilation can be performed.

Can vision lost to glaucoma be restored?
Whether vision lost to glaucoma can be restored depends on the stage of the disease. If treated promptly during an acute attack, some damaged vision may be recovered. However, in the chronic or advanced stages, vision that has already been impaired is usually irreversible, making early intervention essential to control disease progression. To preserve vision, high-risk individuals—such as those with a family history of glaucoma or elevated intraocular pressure—should undergo regular eye examinations.
