Binocular contrast sensitivity testing for low vision patients.

Contrast sensitivity testing is often included in primary care and low vision examinations. This test is designed to provide information regarding the quality of a patient's vision. This clinical study provides a method to assess the binocularity of a low vision patient with contrast sensitivity testing. The method allows the practitioner to determine if monocular or binocular conditions are optimal for the use of a near low-vision device.

Behind the lens telescope: a new concept in bioptics.

A new concept in bioptic prescriptions is presented. The new Behind-The-Lens (BTL) telescope provides the advantages of the typical bioptic with the additional advantage of providing a more acceptable appearance.

Type-size variability for near-point acuity tests.

We measured the sizes of the test forms (letters, digits, and symbols) on 19 different near-point acuity cards. The results are all expressed in the M notation (1 mm of letter height equals 0.7 M) and are tabled according to the acuity specification system used by the manufacturers--such as, the point-type system, Jaeger notation, equivalent 20-ft Snellen notation, and so on. Our results demonstrate that manufacturer's specifications on near-point acuity cards cannot be used to determine the sizes of test letters. The M system has sufficient advantages over other systems to warrant its universal use for specifying near-point visual acuity.

Applied genetics for the practicing optometrist.

A good preventive blindness program includes a strong program in genetic counseling. Optometrists can be of substantial assistance to a genetic counseling program by: 1) being informed of the various types of inherited ocular disorders, and their modes of transmission. 2) becoming aware of the presence of disorders in other members of the patient's family, and 3) encouraging the affected family members to seek genetic counseling prior to conception. This article is designed to serve as a guide for familiarizing the practicing O.D. with the various types of inheritance patterns, specific disorders which follow these inheritance patterns, and some of the ocular and systemic characteristics of the disorders. Only those anomalies of structure and/or function which have an identifiable (and therefore a predictable) genetic mode of transmission will be discussed. This article is intended to serve as a brief and general review of some of the more common ocular disorders, and not as a comprehensive text on the genetics of ophthalmic diseases. Emphasis is placed on the optometric management of each disease discussed.

Applied genetics for the practicing optometrist. Part II.

Part I included a discussion of the four modes of single gene inheritance and examples of ocular anomalies which follow these modes. Part II will conclude the discussion by presenting other transmission forms in conjunction with examples of ocular anomalies characteristic of each. These two articles are designed to serve only as a guide for familiarizing the practicing O.D. with the various types of inheritance patterns, and not as a comprehensive text on the genetics of ophthalmic diseases. The reader is referred to the reference list for in-depth information regarding specific disorders.

High power lens with a measurement water cell.

A simple water cell can be used to increase the range of an ordinary lensometer by about three times by using an application of Snell's law. This technique can be very useful in low vision applications where other methods of measuring high plus ophthalmic lenses are always cumbersome and time consuming and sometimes inaccurate or inconclusive.

A training sequence for low vision patients.

A structured training program for teaching low vision patients to efficiently use their optical aids for reading tasks is presented. The arguments for the use of this particular training sequence is supported through the sample patient histories. The training sequences can be developed in any low vision practice and the materials are readily available. The importance of training in a low vision program is emphasized.

Training a patient to drive with telescopic lenses.

An interdisciplinary approach to licensing partially-sighted individuals to drive is presented. The model includes the participation of optometry, special education, and the department of motor vehicles.
