4 signs of eye cancer that are easily confused with common eye diseases

Eye cancer is a rare but very dangerous disease that threatens vision and life if not detected early. Many of the early signs of eye cancer are similar to common eye problems.

Warning signs of eye cancer that are easily confused with common eye problems include:

Blurred vision may be related to eye cancer you need to know to protect your health

One of the first signs of eye cancer is a sudden change or gradual blurring of vision. This is often mistaken for nearsightedness, farsightedness, or simply eye strain from electronic devices. However, if the blurred vision occurs in one eye, persists, and does not improve with rest, this could be a sign of melanoma developing inside the eye, according to the health website Verywell Health (USA).

Blurred vision occurring in one eye and lasting for a long time can be a sign of eye cancer.

The tumor may be pressing on the retina, distorting vision and causing loss of central or peripheral vision. According to the American Academy of Ophthalmology (AAO), any unexplained vision changes should be investigated with an ophthalmoscopy or ultrasound.

Black spots appear in vision

Having dark spots, shadows, or the sensation of “floaters” is often considered normal due to aging or changes in the vitreous. However, when this symptom becomes noticeable, lasts a long time, or increases rapidly, it can be a sign of a growing tumor in the eye.

In the case of intraocular melanoma or lymphoma, the tumor changes the structure of the vitreous or causes retinal hemorrhage, leading to the appearance of the above symptoms.

Pupils change color

The pupil in a normal eye is black and reacts to light. However, if the person or a loved one sees an unusual white or bright spot in the pupil when taking a photo, especially in children, it could be a sign of retinoblastoma.

In addition, tumors can also cause the pupils to dilate abnormally, lose their reflex to light, or become yellow-white. This change in pupil color can easily be mistaken for a birth defect or a side effect of medication.

Eye pain or feeling of pressure

Eye cancer is usually painless in its early stages. But as the tumor grows and spreads to surrounding tissues, it can cause pain in or behind the eye, which can be mistaken for headaches, glaucoma, or conjunctivitis.

Some patients describe a feeling of a foreign body in the eye, pressure when moving, or severe pain when touched. If eye pain is accompanied by blurred vision, eyelid swelling, or an abnormally dilated pupil, prompt medical attention is needed to rule out an eye tumor or cancer metastasis from another location in the body, according to Verywell Health.
