Symptoms of optic nerve malignancy?

summary

Ocular tumors include eyelid, conjunctiva, ocular tissues and ocular appendages. Benign or malignant tumors can damage the eye tissue and its function. Malignant tumors can damage the eyeball and visual function, and can spread to periorbital, intracranial or systemic metastasis. Malignant tumors in some parts of the body can also be transferred to the eye, but if they expand into the brain through the optic foramen or supraorbital fissure, they can also threaten the lives of patients and cause serious consequences. Symptoms of optic nerve malignancy? Let's talk about it

Symptoms of optic nerve malignancy?

At the beginning of the growth in the eye, the outer eye is normal. Because the child is young, he can't tell himself whether he has visual impairment, so it's not easy to be found by his parents in the early stage of the disease. When the tumor proliferates into the vitreous body or close to the lens, yellow light reflex will appear in the pupil area, so it is called amaurous cat eye. At this time, parents often find mydriasis, white pupil or strabismus due to visual impairment. Fundus changes: round or oval, clear boundary, single or multiple, white or yellow nodular uplift, uneven surface, different sizes, neovascularization or bleeding point.

The tumor originated from the inner nuclear layer and developed into the vitreous body, which was called endophytic type; Those who originate from the outer nuclear layer and tend to grow to choroid are called exophytic type, which often leads to non perforated solid flat detachment of retina. Slit lamp examination, there may be tumor cell colonies in the anterior chamber, the formation of pseudohyphema, corneal deposition, the formation of gray tumor nodules on the iris surface, which can provide some clinical basis for early diagnosis.

As the tumor grows gradually, the volume increases and the content of the eye increases, the intraocular pressure rises, causing secondary glaucoma, such as eye pain, headache, nausea, vomiting and redness. Children's eyeball wall is more elastic, long-term high intraocular pressure can make the ball wall dilate, eyeball expand, form a special appearance of the so-called "bovine eye", cornea, corneoscleral staphyloma, so it should be differentiated from congenital glaucoma.

matters needing attention

Including tumor resection, enucleation and enucleation. The specimens were sent for pathological examination. The radiology department was invited to consult, and deep X-ray, CO and other deep irradiation, or P, Sr and other shallow irradiation were used, according to the routine treatment of radiotherapy. Comprehensive application of traditional Chinese medicine, western medicine, radiotherapy and surgery.
