Judgment of tumor inside the eye is based on changes in the appearance of the eye, such as the presence of protruding eyeballs, strabismus of the eye, ptosis and other signs of appearance. In addition, it is also judged according to eye function, such as vision loss, blurred vision, visual field defects and other eye vision and visual function. Tumors in the eye can be divided into benign and malignant, which usually occur in the orbit, eyeball, eye appendages, fundus, eyelid, conjunctiva, etc. Children under the age of 10 are the most prevalent group, and more males than females have rapid onset and are prone to malignant changes. Benign ocular tumors are usually neurogenic tumors, vascular tumors and dermatomal cysts. Benign ocular tumors have slow growth rate, clear borders and envelope, mostly outward growth and bulging development, and have good prognosis after regular treatment. Malignant eye tumors often include ciliary body tumors and choroidal lymphoma. Malignant ones are more likely to metastasize and develop rapidly, and the cancer cells can invade the nasal cavity, sinuses and skull.
