What is Stargardt Disease?

Stargardt disease, also known as Stargardt macular dystrophy or juvenile macular degeneration, is a condition that involves the retina of the eye. The retina is the layer of the eye which is responsible for sensing light. Most people with Stargardt disease have some loss of vision at a young age, either as a child or an adolescent, although some people may retain good vision until adulthood. It is estimated that about 1 in 10,000 people has Stargardt disease.

Ophthalmology

Ophthalmology is the specialized field of medicine that focuses on the health of the eye. It includes the anatomy, physiology and diseases that may affect the eye. Historically, the science of ophthalmology encompassed all aspects of visual function, both in health and in illness. Additionally, ophthalmology also includes animal eyes as ocular function and optic diseases are similar among humans and animals.

Eyelid Cancer

Eyelid cancers refer to the several types of malignant cell growth on the eyelid. Whatever the type, the tumor is graded by the differentiation seen in the cells, and the rate of proliferation. Basal cell carcinomas and squamous cell carcinomas are the most frequent. Cancers which do not belong to these groups are rare but occur with a six-fold increased incidence in elderly white patients.

What Does a Sentinel Node Biopsy Involve?

The sentinel node is the first lymph node that filters lymphatic fluid from the tissue surrounding a tumor. As the first node in the lymph circulatory system “downstream” from the tumor, this is more likely to show the presence of migrating tumor cells than any other.

Radial Scar Diagnosis and Management

Radial scars (RS) are benign, tumor-like lesions which are most commonly an incidental finding during mammography. When they are greater than 1 cm in diameter, they are referred to as complex sclerosing lesions. The recent widespread use of imaging techniques such as mammography has led to the identification of features characteristic of this lesion.
