Dear Readers,
The theme of this issue of Sitenews in Ambylopia. First it seeks to understand what exactly the problem is. It looks into the magnitude of the problem. It also seeks to examine the cost implications of setting up this. Resources which present the different barriers that prevent the uptake of the treatment process are also provided. As well as resources which provide an overview over the treatment process? What are the health education materials for this is also presented.
The featured organization is Prevent Blindness America.
Hope this issue will impart the resources which are worth to be read. We wish you an experience of learning that is very practical. Your feedback will let us know how we can improve. Please write in your feedback at eyesite@aravind.org. We look forward to your feedback.
Wish you a productive reading!

Happy reading!
Regards,

      Amblyopia may be caused by any condition that affects normal visual development or use of the eyes. Amblyopia can be caused by strabismus, an imbalance in the positioning of the two eyes. Strabismus can cause the eyes to cross in (esotropia) or turn out (exotropia). Sometimes amblyopia is caused when one eye is more nearsighted, farsighted, or astigmatic than the other eye. Occasionally, amblyopia is caused by other eye conditions such as cataract.
   
  • AMBLYOPIA


  • THE RELATIONSHIP BETWEEN ANISOMETROPIA, PATIENT AGE, AND THE DEVELOPMENT OF AMBLYOPIA

  • Abstract
    A statewide preschool photoscreening program screened 120,000 children and identified 792 with anisometropia greater than 1.0 diopter. Age was correlated with visual acuity and amblyopia depth. Data were compared with those from 562 strabismic children similarly identified.

      Amblyopia is the most common cause of visual impairment in childhood. The condition affects approximately 2 to 3 out of every 100 children. Unless it is successfully treated in early childhood, amblyopia usually persists into adulthood, and is the most common cause of monocular (one eye) visual impairment among children and young and middle-aged adults.

      There is a huge need to develop a setting up of systematic model that determines the costs, effectiveness, and cost-effectiveness of four screening strategies to detect amblyopia or amblyogenic factors in pre-school children and to apply the model in a various setting. Here are some articles which touch upon setting up for treating amblyopia.

      Treating amblyopia involves making the child use the eye with the reduced vision (weaker eye). Currently, there are two ways used to do this:

Atropine
A drop of a drug called atropine is placed in the stronger eye once a day to temporarily blur the vision so that the child will prefer to use the eye with amblyopia. Treatment with atropine also stimulates vision in the weaker eye and helps the part of the brain that manages vision develop more completely.

Patching
An opaque, adhesive patch is worn over the stronger eye for weeks to months. This therapy forces the child to use the eye with amblyopia. Patching stimulates vision in the weaker eye and helps the part of the brain that manages vision develop more completely.
     Previously, eye care professionals often thought that treating amblyopia in older children would be of little benefit. However, surprising results from a nationwide clinical trial show that many children age seven through 17 with amblyopia may benefit from treatments that are more commonly used on younger children. This study shows that age alone should not be used as a factor to decide whether or not to treat a child for amblyopia.

      Health education helps individuals and groups of people learn to behave in a manner conducive to the promotion, maintenance or restoration of health. The ultimate aim of Health Education is Positive Behavioural Modification.

     As far as Paediatric eye care is concerned a lot of health education materials have to be developed for creating awareness about the eye diseases. We have provided you with the links of various health education materials that can be used by you to get awareness of Amblyopia.

PREVENT BLINDNESS AMERICA
      Founded in 1908, Prevent Blindness America is the nation's leading volunteer eye health and safety organization dedicated to fighting blindness and saving sight. Focused on promoting a continuum of vision care, Prevent Blindness America touches the lives of millions of people each year.

We screen. We check the eyes of millions of children and adults each year. Our vision screenings help preschoolers at risk of vision loss from lazy eye (amblyopia), school children who depend on good vision for learning, and adults threatened by glaucoma and other serious vision problems.

We educate. We get the word out on better eye health through brochures, fact sheets, public service announcements, newsletters, media campaigns, special events and the web. Every year more than 120 million people read, hear or see our messages about early detection of eye disease and prevention of accidents that can cause permanent loss of sight.

We advocate. We work with government officials at the state, local and national levels - building grassroots advocacy movements that will improve our nation's public health policies.

We support groundbreaking vision research. We support the work of scientists who will find tomorrow's cures for the eye diseases that threaten Americans with vision loss and blindness.

We train. We train and certify adult and children's vision screeners and screening instructors through the only national program of its kind, providing 20,000 vision screening personnel with the skills they need to help people in their communities.

We are in your community today. We improve the quality of life for hundreds of thousands through our community programs. Our websites, www.preventblindness.org, www.diabetes-sight.org and our PBA Vision Health resource Center (1-800-331-2020) put us within reach of anyone with Internet access or a telephone.
