What is considered a rainbow phenomenon, can it be used as a basis for judging glaucoma?

The phenomenon of rainbow vision generally refers to the appearance of a rainbow-like halo when exposed to strong light. The iridus phenomenon can be used as an adjunct diagnostic method for glaucoma.

Iridium is a phenomenon caused by poor circulation of fluid inside the eyeball, resulting in light rays that cannot disperse normally after entering the eye. When the patient is in the dark, the pupil dilates to allow more light to enter the eye. At this time, under strong light, a rainbow-like aura can be seen around the eyeball. Iris is often seen in acute angle-closure glaucoma, because this type of glaucoma causes obstruction of the flow of aqueous humor, causing symptoms such as increased intraocular pressure and blurred vision.

However, iridance is not a specific symptom of glaucoma, and some other eye diseases may present with similar symptoms. If glaucoma is suspected, it is advisable to seek medical attention promptly for an examination and treatment according to the doctor's guidance. Patients diagnosed with glaucoma can be treated with medications, lasers, or surgery to control the progression of the disease and preserve vision.

The iridus phenomenon can also be used to observe changes in intraocular pressure. By monitoring changes in the iridus phenomenon, doctors can be able to assess the patient's condition and develop a treatment plan accordingly. The iridis phenomenon cannot be used as a diagnostic indicator of glaucoma alone, and it needs to be comprehensively judged in combination with other clinical manifestations and laboratory test results.
