Clinical InformationClinical

  • Ciliary Body

    a ring of tissue extending from the scleral spur to the ora serrata of the retina. it consists of the uveal portion and the epithelial portion. the ciliary muscle is in the uveal portion and the ciliary processes are in the epithelial portion.

  • Spasm

    an involuntary contraction of a muscle or group of muscles. spasms may involve skeletal muscle or smooth muscle.

  • Uveal Melanoma

    a rare, malignant melanoma arising from the melanocytes of the uvea.

  • Schlemm's Canal

    a circular vascular-like structure in the anterior chamber of the eye bounded anterolaterally by the internal scleral sulcus and posteriorly by the trabecular meshwork. it is a part of a pathway where the aqueous humor from the anterior chamber of the eye passes through the trabecular meshwork, drains into the lumen of schlemm’s canal, and subsequently returns to blood circulation into the veins of the sclera.

  • Sclera

    the white, opaque, fibrous, outer tunic of the eyeball, covering it entirely excepting the segment covered anteriorly by the cornea. it is essentially avascular but contains apertures for vessels, lymphatics, and nerves. it receives the tendons of insertion of the extraocular muscles and at the corneoscleral junction contains the canal of schlemm. (from cline et al., dictionary of visual science, 4th ed)

  • Scleral Buckling

    an operation for retinal detachment which reduces the size of the globe by indenting the sclera so that it approximates the retina.

  • Scleral Diseases

    general disorders of the sclera or white of the eye. they may include anatomic, embryologic, degenerative, or pigmentation defects.

Patient EducationClinical

Eye Cancer

Cancer of the eye is uncommon. It can affect the outer parts of the eye, such as the eyelid, which are made up of muscles, skin and nerves. If the cancer starts inside the eyeball it's called intraocular cancer. The most common intraocular cancers in adults are melanoma and lymphoma.
