Lattice Degeneration with Atrophic Holes

The eye works like a camera. It has two parts, a lens and a film. The film layer lines the back wall of the eyes and is called the retina. The back surface of the retina receives its blood supply from a pigmented layer called the choroid.

It is very common for patients to develop areas of increased pigmentation in the choroid over time. These circular areas of pigmentation are called choroidal nevi. Choroidal nevi are common occurring in approximately 8 percent of caucasian individuals. They do not cause any changes in vision and do not usually change in size over time.

The biggest risk of having a choroidal nevus is transformation into a choroidal melanoma. The risk of choroidal melanoma developing is 1 in 8000 individuals. Choroidal melanoma is a treatable condition, although the risk of developing this condition is extremely low.

There are no actions required by the patient to decrease the risk of the nevus transforming into a choroidal nevus. Patients who notice decreased vision or a significant change in their peripheral vision should be re-evaluated. Choroidal nevus does not cause any change in the prescription of glasses that a patient requires.

Most patients with a choroidal nevus are evaluated every 3-6 months, depending on the features of the nevus.

Please reach out to your eye care specialist if you have additional questions or concerns.Β 

Nevo coroideo - caracterΓ­sticas de bajo riesgo

Nevo coroideo – caracterΓ­sticas de bajo riesgo

El ojo funciona como una cΓ‘mara. Tiene dos partes, una lente y una pelΓ­cula. La capa de pelΓ­cula recubre la pared posterior de los ojos y se llama retina. La superficie posterior de la retina recibe su suministro de sangre de una capa pigmentada llamada coroides.

Es muy comΓΊn que los pacientes desarrollen Γ‘reas de pigmentaciΓ³n aumentada en la coroides con el tiempo. Estas Γ‘reas circulares de pigmentaciΓ³n se llaman nevos coroideos. Los nevos coroideos son comunes en aproximadamente el 8 por ciento de las personas caucΓ‘sicas. No causan ningΓΊn cambio en la visiΓ³n y generalmente no cambian de tamaΓ±o con el tiempo.

El mayor riesgo de tener un nevo coroideo es la transformaciΓ³n en un melanoma coroideo. El riesgo de desarrollar melanoma coroideo es de 1 de cada 8000 individuos. El melanoma coroideo es una afecciΓ³n tratable, aunque el riesgo de desarrollar esta afecciΓ³n es extremadamente bajo.

El paciente no requiere acciones para disminuir el riesgo de que el nevo se transforme en un nevo coroideo. Los pacientes que notan una disminuciΓ³n de la visiΓ³n o un cambio significativo en su visiΓ³n perifΓ©rica deben ser reevaluados. El nevo coroideo no causa ningΓΊn cambio en la prescripciΓ³n de anteojos que requiere un paciente.

La mayorΓ­a de los pacientes con un nevo coroideo se evalΓΊan cada 3-6 meses, dependiendo de las caracterΓ­sticas del nevo.

ComunΓ­quese con su especialista de atenciΓ³n ocular si tiene preguntas o inquietudes adicionales.Β
