What kind of doctor treats Hereditary Retinoblastoma?
An ophthalmologist usually leads care, often with pediatric cancer specialists at a center experienced with this rare cancer. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is hereditary retinoblastoma?
Hereditary retinoblastoma is a rare cancer of the eye. It starts in the retina, which is the light-sensing tissue at the back of the eye. It is caused by a changed gene that can be passed from parents to children. It usually appears in babies and young children, often before age five.
Retinoblastoma is a tumor that forms in the retina, the tissue that turns light into vision. In the hereditary form, this tendency is inherited, and it often affects both eyes.
Symptoms
The most common early sign is a white glow in the pupil, often noticed in flash photographs. Other signs include misaligned, red, or painful eyes and poor vision. Many children show no symptoms, so regular checkups matter for at-risk families.
Causes and who gets it
It is caused by a change in the RB1 gene, which normally acts like a brake on cell growth. The change can be inherited or happen for the first time before birth. Affected children may have tumors in both eyes and a higher chance of other cancers later.
How doctors diagnose it
An eye doctor can usually see the tumor during an exam. Ultrasound can show its size and shape. Genetic testing on blood or saliva can confirm whether a child carries the changed RB1 gene.
Treatment
Treatment depends on whether one or both eyes are affected and how large the tumor is. Doctors aim to save life first, then the eye, then vision, using chemotherapy, laser or freezing treatments, and sometimes surgery. Most children in the United States survive.
When to see a doctor
See a doctor right away if a child's eye shows a white glow in photos, misaligned eyes, or redness, swelling, or pain. Children with a family history should be checked soon after birth.
How a direct primary care or concierge doctor fits in
A direct primary care doctor is paid a flat monthly fee instead of billing insurance; a concierge doctor usually charges more and often works alongside insurance. Either can monitor a child's general health and coordinate care with specialists, though they cannot treat the cancer itself.
Common questions
Will my other children get retinoblastoma?
If a parent carries the changed RB1 gene, each child has a chance of inheriting it. Genetic testing can show which family members carry the gene. Children who carry it need regular eye exams in early childhood.
Can hereditary retinoblastoma be cured?
Most children treated in the United States survive this cancer, but results differ from person to person. Some children keep useful vision, while others may lose an eye. Lifelong follow-up is needed because of the chance of other cancers later.
Does having the RB1 gene change mean a child will definitely get cancer?
Not every child with the gene change develops a tumor, though the risk is high. Some children with the gene never have eye tumors. Regular eye exams help doctors find and treat tumors early if they appear.
Can adults get hereditary retinoblastoma?
Retinoblastoma almost always appears in babies and young children. Adults who had the condition as children need long-term monitoring for other cancers. A primary care doctor can help arrange that follow-up.
