Often, a retinoblastoma will not cause any symptoms unless it spreads to distant parts of the eye. In this case, aggressive treatment will be necessary, and clinical trials may be an option. The following are symptoms you may experience if your retina is affected by retinoblastoma. Listed below are a few of the most common symptoms of the disease.

Poor Vision. Symptoms of poor vision may include bumping into things and falling more often. Children may also have trouble moving around the house and bring objects close to their face to see more clearly. If these symptoms persist, you should make an appointment with a doctor. There are several other signs that your child may have retinoblastoma. If you are concerned about your child's vision, consider scheduling an appointment with an ophthalmologist to get an accurate diagnosis.

Retinoblastoma symptom screening can be delayed if the symptoms persist. In the meantime, a child with these symptoms may need to go to an ophthalmologist or children's eye doctor for a retina scan. To perform a proper screening, the eye doctor will dilate the pupil. They will also perform a red reflex test. This test will help your doctor determine whether your child has retinoblastoma.

If you notice an opaque white patch in your child's pupil, this could be a sign of retinoblastoma. This can be difficult to spot and may require a trip to the doctor's office. This condition may cause vision loss, so it's important to see an ophthalmologist as soon as possible. While the condition is rare, the symptoms may be similar to those of other health conditions.

Treatment for retinoblastoma varies, but treatment options depend on the stage of the disease and risk factors. Chemotherapy can shrink or destroy tumor cells, stopping them from multiplying. The radiation is delivered through a tiny device placed over the eye. After treatment, the device is removed. Depending on the size of the tumor, the entire eyeball or a part of the optic nerve may have to be removed. Alternatively, an artificial eyeball or lens can be placed in the eye socket, similar to a contact lens.

In children who have hereditary retinoblastoma, doctors recommend multiple eye exams throughout their first year of life. During these examinations, the doctor may detect tumors in both eyes at different times, which is important for minimizing the chance of death and other problems. If your child has one eye with retinoblastoma, they should see their pediatrician as soon as possible.

Hereditary retinoblastoma is caused by a mutation in the RB1 gene. In most cases, children with the inherited form develop multiple tumors in both eyes, but a small percentage of them do not have this mutation. In contrast, the non-heritable form develops only one eye. The non-heritable form of retinoblastoma is characterized by an acquired mutation in both copies of the gene.

Retinoblastoma is a rare form of eye cancer that begins in the retina, the light-sensitive tissue at the back of the eye. It usually runs in families, and most cases affects children under the age of two. Patients with bilateral retinoblastoma may also develop tumors in the pineal gland. Furthermore, if the tumor is in the eye, the patient is at risk of developing osteosarcoma.

A family history of retinoblastoma may also increase the risk of getting other types of cancer. If either parent had the retinoblastoma gene mutation, there is a 50% chance that their children will have it. The disease is hereditary in 25 to 30% of cases. Hereditary retinoblastoma patients are more likely to have both eyes affected and tumors in both eyes. Hereditary retinoblastoma is associated with an increased risk of childhood brain tumors and osteosarcoma in children.
