Juvenile macular dystrophy, distinct from age-related macular degeneration (AMD), is a group of inherited eye disorders that affect children and young adults. This hereditary condition, unlike AMD which occurs with aging, affects the macula, a tiny area of the retina crucial for detailed vision. In this article, with the help of specialists from Clínica Nivaria in Santa Cruz de Tenerife, we'll tell you all about it.
What is Juvenile Macular Dystrophy?
This condition involves the loss of central vision, crucial for activities requiring visual precision, such as reading or recognizing faces. Stargardt disease is the most common form of juvenile macular dystrophy, but other variants exist, such as Best disease and juvenile retinal schisis, all characterized by the loss of central vision.
Common symptoms
Those affected experience problems with central vision, perceiving blurred, distorted images or dark areas, while peripheral vision generally remains intact. Symptoms usually appear in childhood or adolescence, affecting both eyes unevenly.
Risk and inheritance:
Juvenile macular dystrophy is an inherited genetic disorder, with different inheritance patterns depending on the specific type of the disease. Stargardt disease, for example, is usually recessive, requiring both parents to carry the defective gene, while Best disease is inherited in a dominant manner, requiring only one gene from one parent to develop the condition.
Diagnosis
Diagnosis is made through a detailed eye examination, including pupil dilation for a thorough inspection of the retina. Techniques such as optical coherence tomography (OCT) and fluorescein angiography help confirm the presence of the disease, revealing specific features such as lipofuscin deposits in Stargardt disease or cyst formation in Best disease.
Current treatments and future hopes
Although there is currently no cure for juvenile macular dystrophy, promising treatments such as gene therapy, which aims to correct the abnormal gene in the retina, are being explored. Wearing sunglasses to protect the eyes from UV light and using low-vision assistive devices are practical recommendations for managing the condition.
Genetic diagnosis is fundamental to identifying the specific gene responsible, opening the door to personalized treatments and participation in clinical trials seeking innovative solutions.
