Tumor detection through the eyes

EThe eye is closely related to any process systemically.

The eye, contrary to what many believe is not fully independent from the body with its own pathology and isolated operation, but is closely related to any systemic process. In fact it is the most vascularized organ in the human body in proportion to their size, which means that any vascular pathology will be detected early in the eye and any pathology disseminated by blood, such as infections, tumors and some autoimmune diseases. Moreover, if we recall the ocular anatomy, we can say that the eye is a continuation of the brain, because the fibers of the optic nerve (cranial nerve II) exiting the eye with sensory information connects to different brain areas responsible for different functions, from shaping image to the regulation of circadian rhythms (the light stimuli inform our brain about whether it is day or night allowing it to act according to the situation).

Taking all this into account, we can imagine the great utility of visualizing the inside of the eyeball, because this gives us a fairly accurate picture of what is happening in the rest of our body's systems, so the eye is acting as a window to view the body.

Focusing on tumor pathology, it may be primary (tumor originated in the eye) or secondary / metastasis (tumor originated elsewhere in the body that has spread to the eye), which is most common because 10% of all tumors metastasize in the eye. The tumors originated a extraocular level more frequently metastasize to the eye are, in women, breast cancer (approximately 70% of cases), followed by lung cancer, and in men, lung cancer (by approximately 60% of cases), followed by tumors of unknown cause, and kidney, prostate and testis. Therefore, it is important, once a tumor is detected in the eye, to do a full metastatic study, paying particular attention to the above locations. In fact, 25% of patients with metastatic carcinoma detected in the eye, the ocular manifestation appears to be the first demonstration of the tumor. In the case of lung cancer, the figures are even higher: in half of the patients the existence of the primary lung tumor is detected through the ophthalmologist. That is, the finding of ocular tumor allows us to make an early diagnosis of primary cancer and therefore to provide a much more effective (with more favorable results) treatment for the patient. Also keep this in mind in the opposite case, i.e. when the ocular tumor is primary, because early detection and proper treatment will prevent its spread (metastasize) to other organs.

To differentiate a primary ocular tumor (in adults, usually melanoma) from one metastatic we could roughly say that metastatic tumors are multiple (multiple tumor masses in the same eye) and / or bilateral (tumor masses in both eyes) in approximately 20% of cases, being much less in the primary ocular melanoma. In addition, secondary tumors usually have a significantly higher growth rate.

In terms of symptoms that occur with the presence of tumor at the eye level highlights the blurred and distorted vision in one or both eyes, depending on the tumor extension. The pain is not usually an accompanying symptom, not being that tumor mass was highly developed and occupying such a volume, which causes a secondary glaucoma or other eye disease that may cause pain.

Therefore, it is advisable to keep an periodic review of the eyes, for detecting any disease (ocular or extraocular) at early stages. This is the best way to ensure an effective treatment. Proper eye care not only ensures good health for the eyes, but for the rest of the body as well.
