Shortly after fertilization as the embryonic cells divide quickly going from two cells to 128 cells. This is called a blastula. The blastula has a spherical layer of cells called the blastoderm. The blastoderm consists of three layers—the endoderm, mesoderm and ectoderm.

Eye Disorders And Triage Everyone In Optical Should Know

Monday, November 14, 2011 6:29 AM Improper triage is a major factor in malpractice claims, making it critical for any office staff member who answers the telephone, from the receptionist to the optician, to be trained in recognizing possible emergencies and scheduling patients appropriately.

Iris, Pupils

By Julie Harp, CPOT, ABO, NCLE
Thursday, November 10, 2011 3:34 AM The iris is a circular structure located in the anterior chamber surrounding the pupil. It contains four layers and two muscles: The sphincter muscle, which shrinks the pupil on contraction, and the dilator muscle, which dilates it.

Lids

By Julie Harp, CPOT, ABO, NCLE
Thursday, November 10, 2011 3:34 AM The most anterior structures affecting contact lens fit are the eyelids. The eyelids have three main functions.

Conjunctiva

By Julie Harp, CPOT, ABO, NCLE
Thursday, November 10, 2011 3:32 AM The conjunctiva is divided into two main sections: the palpebral, lining the undersurface of the lids, and the bulbar covering the sclera.

The Cornea

By Julie Harp, CPOT, ABO, NCLE
Thursday, November 10, 2011 3:30 AM Of utmost importance in the fitting process is the preservation of corneal health. Any disruption of metabolism can cause loss of tissue transparency and decreased visual acuity.

The Tear Film

By Julie Harp, CPOT, ABO, NCLE
Thursday, November 10, 2011 3:27 AM The tear film is the first and most directly influential factor in the fitting process. It represents the initial point of interface between the contact lens and the eye.

Corneal Topography

By Julie Harp, CPOT, ABO, NCLE
Thursday, November 10, 2011 3:10 AM In order for a contact lens to fit appropriately it must approximate the curvature of the cornea. A thorough knowledge of corneal topography is therefore a must in any contact lens fitting.

Overview: Knowing Eye Anatomy and Physiology

By Staff
Thursday, November 10, 2011 3:09 AM The tear flow, so important in corneal metabolism, must never be impeded by a badly fitting lens. Trading one type of blurred vision for another is certainly not the goal.

Anatomy and Physiology, Contact Lens Considerations

By Julie Harp, CPOT, ABO, NCLE
Thursday, November 10, 2011 2:40 AM Having a thorough working knowledge of ocular anatomy is not only helpful but also essential for successful contact lens fitting.
