Understanding The Retinal Examination
As Part Of A Comprehensive Eye Exam
There are many eye disorders that can only be detected by retinal examination. Most eye diseases cannot be recognized by the patient until the disease is in very late stages. This is because:
- Visual acuity of 20/20 can remain intact even though peripheral retinal damage has already occurred.
- The eye rarely "hurts" when something is wrong.
Our doctors strongly recommend that patients have both Optomap photography and pupil dilation as part of a comprehensive eye examination.
OPTOMAP PHOTOGRAPHY
- Can be performed without pupil dilation.
- Provides a digital computerized map of the retina.
- Provides an in-depth view of the retinal layers where disease can start.
- Provides the ability to view images of a patient's own eye during an exam.
- Provides a permanent record for a medical file. This allows year-to-year comparisons for tracking and diagnosing potential eye disease.
- Eliminates the discomfort and inconvenience many people associate with pupil dilation. As a result, a patient will not experience blurred vision or light sensitivity following an eye examination.
PUPIL DILATION
- Allows the doctor a thorough examination of the retina. Only about 45% of the retina can be seen through a normal-sized pupil.
- Enlarges pupils temporarily. This creates sensitivity to sunlight, but sunshades are provided.
- Blurs near vision for approximately four hours, but distance vision is usually fine with glasses or contact lenses.
MORE DIAGNOSTIC TESTS
THRESHOLD VISUAL FIELD TESTING
- Provides detailed analysis of optic nerve function.
- Reveals impaired function from many conditions, including glaucoma, stroke, multiple sclerosis, and even brain tumors.
- Detects very subtle vision losses that may be unnoticeable to a patient.
- Is an invaluable tool for proper diagnosis, treatment monitoring, or referral for specialized care.
CORNEAL TOPOGRAPHY
- Maps the surface curvature of the cornea, producing a detailed description of the shape and power of the cornea.
- Aids in diagnosis, monitoring, and treatment of various ocular conditions, such as:
- Keratoconus
- Corneal Transplants
- Corneal Scars or Opacities
- Corneal Deformities
- Can also be used to aid in fitting specialized contact lenses and planning refractive surgery.
