A Mexico without Ocular Cancer is our most ambitious goal. We want to contribute to Mexico becoming a first world country like the United States, where eye tumors are currently the most curable type of cancer, with a 99% survival rate.

This is a condition that unfortunately occurs in children. That is why in Ancona Ocular we diagnose and treat children with ophthalmological problems, focused on the retina and ocular cancer. We take you by the hand in a fun and friendly way to make the review and therapy a pleasant experience.
For example, the incorporation of stuffed animals has generated in our small patients to improve their attitude when facing their illness and therefore to improve their health status. Now they have a partner to take care of.

The visible signs include the following.

A white color in the central circle of the eye (the pupil), when a light shines on the eye.

An eye that looks deviated or that seems to look in the opposite direction to the other.

Case Experience

Good day to all.
I would like to share our experience with Dr. David Ancona. My name is Monzerrat S. and I am the mother of Lia R., my daughter is two years old and her diagnosis was Retinoblastoma (cancer in the left eye).

I am very pleased to recommend his work and that of his team, because from the beginning to the present we feel we are in the best hands, since the professionalism and medical ability is of a very high level, in addition to always being at the forefront with new techniques and procedures.

They have an immediate attention with a clear and precise communication from doctor to patient, besides great human quality, because we always have their disposition and support, besides being cordial and kind with our daughter and us.

Personally, we feel confident and optimistic, as we have seen that their priority is the well-being of our child, since it is intended to help make it possible to access the appropriate treatments.

Success case

Stefy's evolution

Stefy’s mother, a 2-year-old girl, noticed for the first time a white reflection in her left eye. Out of that detail she did not look sick and played and ran like her little companions. Dr. Ancona and his team diagnosed him with a fairly advanced state of Retinoblastoma, the most common malignant tumor in children that threatens to kill 3,500 Mexican children each year.

Stefy was a candidate for the newest therapy in the world that allows chemotherapy 10 times more powerful directly to the eye, without causing the undesirable effects of conventional chemotherapy such as hair loss, loss of appetite and weight, malaise or even death. After the therapy, the tumor was removed in its entirety, and the orbit was later reconstructed with the help of dermograse grafts and prostheses.

Today Stefy is in good health and is a winner of cancer. Best of all she never felt any pain or negative side effects and could keep her smile throughout the process.
