Retinal Cysts Causes
Depends: Peripheral cysts your are born with. Patients can develop cystic changes in the periphery called retinoschisis. Cysts in the central retina? The macula are usually from leakage of blood vessels from diabetes, vein occlusions, inflammation in the eye (uveitis) and rarely macular pucker, retinitis pigmentosa, and Niacin usage. ...Read more
A cyst is a structure or mass that consists of a cellular lined sac. It is typically filled with fluid but may be filled with solid material. It can be congenital, traumatic, or acquired. They may develop nearly anywhere in the body and usually require complete excision for eradication or they are likely to recur. Fluid filled sacs that are not cellular lined ...Read more
Depends on type: And location. Retinal cysts as in cystoid macular edema occur in the center, cause blurring and are due to inflammation, usually after surgery. Cysts in the peripheral retina are quite normal and are sometimes called "cystic retinal tufts". Occasionally, cystic tufts can be torn by acute vitreous separation causing a retinal tear which may be lasered to prevent detachment. ...Read more
May not be necessary: Cysts of the pars plana area of the retina generally do not require treatment. Macular cysts and holes need to be evaluated and treated by a retinal surgeon. A victrectomy and tissue glue may be necessary. This can be major surgery. Cystoid macular edema is a swelling of the macula that may occur after trauma or surgery, especially cataract surgery. It is usually treated with meds or surgery. ...Read more
My grandma was diagnosed with retina cyst in her right eye. What is the best treatment or thing to do?
Many kinds: A cyst is an abnormal, fluid-filled, epithelially-lined, closed structure -- a definition learned early by every medical student. There are hundreds of types, but the most familiar is the common epidermoid inclusion / "sebaceous" cyst under the skin. Privately I think many of these start with bug bites, but nobody's proved it. Cheers! ...Read more
Calcified cyst: Are you referring to breast cysts with calcified walls? I'm not exactly sure, maybe some inflammatory reaction of the cyst wall. What I do know is that calcified cysts are a radiologist's best friend on mammography...easy to see, and 100% benign. ...Read more
Age: The vitreous jelly changes as we age and it pulls away from the back of the eye (retina) - a posterior vitreous detachment. During this process, if the jelly pulls hard enough on the retina (especially in a thin or weak area) it can tear the retina which can subsequently detach. Other risk factors include myopia, cataract surgery, head/eye trauma, family history, lattice degeneration, etc. ...Read more
Retinal traction: Most retinal rears are caused by traction on the retina by the vitreous gel, sometimes in association with weaknesses in the retina related to high eye nearsightedness, retinal injuries, old retinal scarring, etc. As the eye ages, the vitreous gel naturally liquifies and detatches from the retina, a posterior retinal detachment. Residual areas of traction can cause retinal tears/detachment. ...Read more
Several things: Cysts are fluid containing lesions with a thin lining of cells. Cysts can occur almost anywehre in ovaries, breasts, bones, liver, spleen, thyroid gland, kidneys neck, etc. Usually cyst grows slowly over time with fluid usually secreted by cyst lining. Sometimes more rapid growth can occur with superimposed infection or hemorrhage from trauma. Most cysts are benign. ...Read more
Trappd skin fragment: Due to a minor injury, pimple, etc., a piece of skin gets trapped under the normal skin. It doesn't know it is not on the surface, and so it makes oil and hair and it sheds dead skin normally. All of this accumulates under the surface and forms a small cyst. As more debris is added, the cyst gets bigger and bigger. They are recognized by their overlying enlarged pore and cured by excision. ...Read more
No: I do not know what type of cysts you are thinking of (there are several types, in different locations). But as a generic answer, not cleaning regularly does not cause cysts. ...Read more
Even though some small retinal tears don't cause detachment, if a small tear was to cause one, how long would it take, what's the average time?
Retinal tears: Time till detachment depends on many factors such as location, cause of tear, your age: can take minutes to never. Average depends on above but recommend treatment asap. ...Read more
Many possible causes: As we age, the vitreous may pull away from its attachment to the retina at the back of the eye. If the vitreous pulls hard enough to tear the retina in one or more places, fluid may pass through, lifting the retina off the back of the eye, causing it to detach. Some risk factors for detachment are: nearsightedness, trauma to the eye or a family history of retinal detachment. ...Read more
Congenital: There are usually benign fluid filled sacs that are located in the kidney as a "cyst". Kidney/renal cysts are pretty common. They are congenital, which means they may be inherited or just a result of the process of growth alterations as a fetus from uncertain intrauterine factors. Sometimes they can obstruct the kidney. If you have it on a scan, see a urologist. ...Read more
Synovial fluid: Fills ganglion cysts. These cysts are fluid filled sacs and synovial fluid is what lubricates the joint, fluid enters the cyst through a tiny attachment from the joint and makes the cyst large. This is why activity or force seemingly makes the ganglion larger as more pressure in the joint leaks into the cyst. Typically it's a like one way valve into the cyst but they can drain back spontaneously. ...Read more
