RETINOBLASTOMA Meaning and
Definition
-
Retinoblastoma is a medical term referring to a rare type of cancer that primarily affects the retina, which is the back layer of the eye responsible for detecting light and sending visual signals to the brain. This malignant disease occurs mostly in early childhood and is characterized by the uncontrollable growth of abnormal cells in the retina. These abnormal cells form tumors that can quickly spread to other parts of the eye and, in severe cases, even extend beyond the eye to other organs.
The most common symptoms of retinoblastoma include a white or cloudy appearance in the pupil, known as leukocoria, as well as the presence of a squint or crossed eyes. Other possible signs may include redness, swelling, or pain in the affected eye, although these symptoms are less common.
Retinoblastoma is typically caused by mutations in the RB1 gene, which is responsible for regulating cell division and growth in the body. In some cases, this mutation is inherited from a parent, while in others, it arises spontaneously. Retinoblastoma can occur in one or both eyes, and the severity of the disease can vary, ranging from small isolated tumors to large, multiple tumors in both eyes.
As with most cancers, early detection and prompt treatment are crucial for achieving positive outcomes. Treatment options for retinoblastoma include chemotherapy, radiation therapy, laser therapy, cryotherapy, and surgical removal of the affected eye when necessary. Regular follow-up examinations are also required after treatment to monitor for any signs of disease recurrence.

Etymology of RETINOBLASTOMA
The word "retinoblastoma" is derived from two main parts: "retino-" and "-blastoma".
1. "Retino-" comes from the Latin word "retina", which refers to the light-sensitive layer at the back of the eye. It is a combination of the Latin words "retinere" meaning "to retain or hold back" and "reticulum" meaning "net", referring to the net-like structure of the retina.
2. "-Blastoma" is a suffix commonly used in medical terminology to indicate a tumor or mass composed of immature or developing cells. It derives from the Greek word "blastos" meaning "germ" or "embryo".
Therefore, "retinoblastoma" is a compound word combining "retino-" (relating to the retina) and "-blastoma" (a tumor comprised of immature cells).
