- Did you know many systemic conditions can be first diagnosed through a thorough eye exam? Illnesses including diabetes, high blood pressure, high cholesterol, arthritis, liver disease and others can all be found first in the eye.
- Did you know there are many treatment programs available that can help dry eye sufferers with and without medicine? Medicine like RESTASIS® Ophthalmic Emulsion and Xiidra Ophthalmic drops are prescription medicines that help increase your eyes’ natural ability to produce tears, which may be reduced by inflammation due to Chronic Dry Eye. Dr. Mayo can complete a tear assessment to determine if you could benefit from this or other dry eye therapies.
- Did you know that many children diagnosed with different types of learning disabilities may actually have an undiagnosed vision problem? Public Health Vision Screening alone is not adequate to detect vision issues that can impact a child's learning. All children should have a complete, dilated eye examination with an Optometrist before they enter school. Please see the article below from the Canadian Optometric Association.
The Children's Vision Initiative - The Canadian Association of Optometrists:
THE NEED FOR COMPREHENSIVE VISION EXAMINATION
OF PRESCHOOL CHILDREN
UNDIAGNOSED VISION PROBLEMS: THE HIDDEN EPIDEMIC
Vision disorders are a common pediatric health problem in Canada and the United States. 1,2,3 (Appendix 1)
It is estimated that nearly 25% of school-age children have vision problems. 4-6 Despite the economic, social and health care advances that have occurred in our society, many preschool and school-age children are not receiving adequate professional eye and vision care.
The earlier a vision problem is diagnosed and treated, the less negative impact it will have on a child’s development. 7,8 Undetected and untreated vision problems can interfere with a child’s ability to learn in school and to participate fully in sports and other childhood activities. Visual impairment in children is associated with developmental delays and the need for special education, vocational and social services, often beyond childhood into adulthood. 9
It has been estimated that only 14% of children under 6 years of age receive professional eye care. 1 The early detection and treatment of eye and vision problems needs to be a major public health goal. An important component of this continuum of care is for all children to receive a professional vision examination before entering school.
LIMITATIONS OF VISION SCREENING
Vision screening programs are intended to identify those children who have eye or vision problems that threaten their sight or that impair their ability to develop and learn normally. However, vision screenings are a limited procedure and cannot be used to diagnose an eye or vision problem. A vision screening “failure” only indicates a need for further evaluation and care. 10 Vision screenings are only able to detect a small percentage of those children needing professional vision care.
An eye and vision screening conducted as part of a preschool or school physical cannot substitute for a professional vision examination. Vision evaluations provided by pediatricians or other primary care practitioners generally only include a screening of visual acuity and gross ocular alignment. 11
Vision screening programs provided in public or private schools have been used to try to identify children with vision problems who previously have not had access to an eye and vision examination. However, these vision screening programs vary significantly and often fail to provide the desired result. Although both laws and guidelines exist for the screening of pre-school children, only about 21% are screened for vision problems. 12
Current vision screening methods cannot be relied upon to effectively identify pre-school children in need of vision care. Vision screening may actually serve as an unnecessary barrier to the early diagnosis of vision problems in many children. These programs can create a false sense of security for those children who “pass” the screening, but who actually have a vision problem, and may result in over-referral for those later found not to have an eye or vision problem.13
Many eye and vision problems that can impact a child’s ability to see and learn can be missed during a screening. Just as a blood pressure screening cannot be considered an adequate assessment of a person’s overall health status, a limited vision screening cannot be expected to adequately assess overall eye health and visual abilities.
NEED FOR VISION EXAMINATIONS
Clearly the prevalence of vision disorders present in pre-school age children and the limitations of vision screening programs support the need for and importance of early detection through a comprehensive eye and vision examination by an optometrist or an ophthalmologist. A vision examination is much more extensive than a vision screening or limited pre-school physical. An age-appropriate eye and vision examination of a pre-school child would generally include the following: 14
Patient and family history
Visual acuity measurement
Assessment of refractive status
Evaluation of ocular motility, binocular vision and accommodative function
Ocular health examination
When appropriate, supplemental testing of visual perceptual development may be provided.
Comprehensive vision examinations can only be conducted by eye care professionals with the specialized training needed to make a definitive diagnosis and prescribe treatment. Often specialized equipment and procedures, which are not available as part of a vision screening program, are needed to adequately evaluate a child’s eyes and vision status.
CONCLUSION
Vision screening programs and pre-school physical examinations are not a substitute for a professional eye examination. Countless children are at risk from undiagnosed eye and vision disorders. The only way to prevent years of needless suffering and failure for these children is by early diagnosis through a comprehensive vision examination. Reliance on limited, non-diagnostic, non-validated screenings does not effectively meet the vision needs of our children.
Any undetected vision problem may result in the reduction of the efficiency of the visual system. This may further result in the inability of children to achieve their full potential.
Therefore, all children should receive a comprehensive eye and vision examination assessing and treating any deficiencies in ocular health, visual acuity, refractive status, oculomotility, and binocular vision prior to entering school.
