  • Alstrom syndrome
    Alstrom syndrome is a very rare genetic disorder – one of the rarest in the world, existing in only 266 reported cases in medical books and only 411 patients in 42 countries. First described by Carl Henry Alstrom in 1959, this condition is usually mistaken with Bardet-Biedl syndrome, which has resembling symptoms. However, the Bardet-Biedl syndrome usually have later onset with its symptoms. [read more]

  • Amblyopia
    Amblyopia, commonly known as “lazy eye”, is a visual system disorder characterized by poor vision in one of the eyes. However, the affected eye remains physically normal or out of proportion. This condition affects 1% to 5% of the global population. Poor or no transmission of the visual images to the brain causes lazy eye. This condition usually affects only one eye, but it could occur in both eyes if both are similarly deprived of clear visual images. However, if detected early in life, the chance of successful treatment increases. [read more]

  • Angiomatosis
    Angiomatosis is a condition that refers to “little knots” of capillaries in different organs. Angiomatosis tend to be defined, sponge-like, sharp tumors that are composed of dilated and large cavernous vascular spaces. Angiomatosis often appears in people with Sturge-Weber syndrome, Bacillary angiomatosis, Von-Hippel-Lindau disease and Klippel-Trenaunay-Weber syndrome. [read more]

  • Astigmatism
    Astigmatism is characterized by a mild defect in the curvature of the eye which causes blurry vision. Astigmatism is an easily treatable condition. In astigmatic patients, the cornea or the lens of one eye has a slightly different curvature in one direction from the other. It comes in two forms: corneal astigmatism, characterized by a distorted cornea; and lenticular astigmatism, characterized by a distorted lens. [read more]

  • Cerebral cavernous malformation
    Cerebral cavernous malformation, sometimes known as cavernous angioma, is a disease that affects the central nervous system. The disease may occur sporadically or may be inherited. When one has the disease, there are groups of abnormal blood vessels located in the brain and spinal cord, although in rare cases they are also located in other parts of the body. A cerebral cavernous malformation resembles a raspberry, although it varies in size. The small bubbles are filled with blood, and a special layer of cells called endothelium lines the bubbles.

  • empty sella syndrome
    Empty sella syndrome refers to the medical disorder that primarily involves sella turcica, which is actually a bony structure that is located at the base of the brain that typically protects and surrounds the pituitary gland. Its is a condition that is often revealed during tests for pituitary disorders, when radiological imaging of the pituitary gland reveals a sella turcica that appears to be empty. Empty sella syndrome is found to be more common in women who have overweight issues or those who also have abnormally high blood pressure. [read more]

  • Ependymoblastoma
    Ependymoblastoma is a malignant tumor which is very rarely reported. It is also known as Primitive neuroectodermal tumor or PNET. It usually occurs in children who are under 10 years of age.

  • Turcot Syndrome
    A genetic disease characterized by polyps in the colon in additions to tumors in the brain, Turcot syndrome is the association between familial adenomatous polyposis or hereditary nonpolyposis colorectal cancer. The first reported case was done by Canadian surgeon Jacques Turcot, hence, the name. Turcot syndrome is inherited in an autosomal recessive manner with both parents carrying a Turcot gene and a 1 in 4 risk for each of their boys and girls of receiving both parental Turcot genes and suffering from the syndrome.

  • Vision Problems
    Vision problems are anomalies that affect normal eye function. These disturbances are caused by a variety of factors ranging from genetic defects to environmental exposure. Among the main forms of vision problems are cataracts, blurry vision, refractive errors and swelling corneal blood vessels, as well as partial or total blindness. Vision problems can also be an effect of severe conditions such as eye cancers and other malignant growths. Vision problems can be detected by physical eye examinations and be treated with prescription glasses, contact lenses or eye surgery to restore normal vision. [read more]
