Eye Neoplasm
Eye neoplasm (pronunciation: /aɪ nɪˈɒpləzəm/), also known as ocular tumor, is a type of neoplasm that originates in the eye or its surrounding tissues.
Etymology
The term "neoplasm" is derived from the Greek words "νέος" (neos), meaning "new", and "πλάσμα" (plasma), meaning "formation" or "creation". The term "eye" comes from the Old English "ēage".
Definition
An eye neoplasm is an abnormal growth of cells, or a tumor, in the eye. This can be benign (non-cancerous) or malignant (cancerous). The most common types of eye neoplasms include retinoblastoma, melanoma, and lymphoma.
Symptoms
Symptoms of an eye neoplasm can include blurred vision, loss of vision, eye pain, a visible growth in the eye, and changes in the color of the iris.
Diagnosis
Diagnosis of an eye neoplasm typically involves a comprehensive eye examination, including visual acuity testing, a dilated eye exam, and imaging tests such as an ultrasound or MRI.
Treatment
Treatment for an eye neoplasm depends on the type and stage of the tumor, and can include surgery, radiation therapy, laser therapy, or chemotherapy.
