Introduction
Glaucoma may present with fundus manifestations such as decreased vision, iris changes, and eye swelling. When patients suffer from glaucoma, their vision also declines accordingly. This is because glaucoma can cause the iris to elongate and lose elasticity, leading to myopia. Patients can visit a正规 hospital and, under medical guidance, undergo optometry and wear corrective glasses to alleviate symptoms.
Glaucoma may present with the following fundus manifestations: decreased vision, rainbow-colored halos (chromatopsia), and eye swelling. Specific details are as follows:
1. Decreased Vision
Patients with glaucoma often experience a decline in visual acuity. This occurs because glaucoma can cause elongation of the eyeball and reduced elasticity, leading to myopia. Patients should visit a reputable hospital and, under medical guidance, undergo refraction testing and wear corrective lenses to alleviate symptoms.
2. Rainbow-Colored Halos (Chromatopsia)
In patients with glaucoma, impaired aqueous humor dynamics can lead to corneal edema, causing abnormal light refraction in the visual field. When viewing lights during the day or at night, patients may see colored rings or halos around the light source, often in a regular pattern. This phenomenon is medically known as "halo vision" or chromatic dysphotopsia. Treatment may include prescription eye drops such as timolol ophthalmic solution or brinzolamide ophthalmic solution, as directed by a physician.
3. Eye Swelling
This symptom can stimulate the terminal branches of the trigeminal nerve. When the eyes are exposed to dark environments, nerve stimulation may lead to a sensation of eye swelling, sometimes accompanied by headaches. Treatment options include timolol ophthalmic solution or pilocarpine ophthalmic solution, used according to medical advice.
In addition to the above symptoms, glaucoma may also cause whitening of the eye. In daily life, patients should take proper care of their eyes, avoiding direct exposure to sunlight to prevent worsening of the condition.
