Why do I have sarcoma in my eyes? What is orbital liposarcoma?

The eye is approximately spherical and located in the orbit. The eyeball includes tissues such as the wall of the eyeball, the intraocular cavity and contents, nerves, and blood vessels. The eyeball wall is mainly divided into three layers: outer, middle, and inner.

The outer layer is made up of the cornea and sclera. The first 1 6 is the transparent cornea, commonly known as the "eyeball", and the remaining 5 6 is the white sclera, commonly known as the "white of the eye".

The contents of the eye include aqueous humor, lens, and vitreous. The external light is refracted through the cornea and the transparent contents, focused on the retina of the fundus, and then converted into nerve impulses through the photosensitive transposition of the optic cells, which are transmitted to the visual center of the brain through the optic nerve and optic duct to produce vision.

Aqueous humor is a colorless and transparent aqueous liquid with a total amount and refractive index of. In addition to its refractive effects, aqueous humor nourishes the cornea and lens and maintains intraocular pressure.

The lens is a biconvex elastic hyaline body, the back is more convex than the front, located between the iris and the vitreous, and there is no blood vessel and nerve distribution. The lens is enclosed by the lens capsule, which is transparent and elastic. The lens capsule is suspended on the inner surface of the ciliary process by means of a ciliary band.

The lens capsule surrounds a lens constitution composed of multiple layers of lens fibers, the peripheral part is soft, the fibers are elastic, and it is the lens cortex, and the ** part is dense and hard, and the elasticity is poor, which is the lens nucleus. The refractive index of the lens is about. The lens relies on its own elastic retraction to increase the convexity and enhance the refractive ability.

With age, the elasticity of the lens weakens, and the accommodative power also weakens, that is, "presbyopia" is produced.

The vitreous is a transparent and colorless colloidal body that fills between the lens and the retina, and the vitreous occupies 4 5 of the inner cavity of the eyeball. The refractive index is.

Analysis: Hello, orbital liposarcoma is a malignant tumor of fatty tumors, which occurs more often in adults, and can be seen with the naked eye, which is different from other surrounding tissues.

Guidance: Liposarcoma is more common in adults. The main clinical manifestation is unilateral proptosis and rapid development, so once you feel that there is something unsatisfactory, you should seek medical attention in time.

Analysis: Hello, I think it is a stye, I think this situation should be a local hot compress to promote suppuration, and the light inflammation can also disappear completely after the hot compress. Systemic and topical antibiotics** can promote the loss of inflammation, and penicillin antibiotics can be given orally, intramuscularly, or intravenously, and they are effective against pyogenic bacteria.

Guidance: Topical eye drops can be ordered, generally using 0 25 chloramphenicol eye drops, if there is more secretion, rifampicin eye drops can be used for good effect. Children can apply chlortetracycline eye ointment after falling asleep.

Incision to drain the pus, without waiting for it to break down on its own, can reduce pain and shorten the course of treatment.

The doctor asked:

Problem analysis: Consider pterygium, small and stationary pterygium does not need to be **. Surgical excision may be performed if the gium is progressive or close to the pupillary area, affecting vision or if eye movement is limited.

Suggestions: For patients who are unwilling to undergo surgery, 2000 3000u ml of Zhengguangmycin solution can be injected into the neck and body of pterygium under topical anesthesia, once a week, 3 6 times for 1 course of treatment. To alleviate local reactions, prednisolone and tetracycline cortisone ophthalmic ointment can be injected under the contralateral bulbar conjunctiva.
