It's important to start treatment for lazy eye as soon as possible in childhood, when the complicated connections between the eye and the brain are forming. The best results occur when treatment starts before age 7, although half of children between the ages of 7 and 17 respond to treatment.
Treatment options depend on the cause of lazy eye and on how much the condition is affecting your child's vision. Your doctor might recommend:
- Corrective eyewear. Glasses or contact lenses can correct problems such as nearsightedness, farsightedness or astigmatism that result in lazy eye.
- Eye patches. To stimulate the weaker eye, your child wears an eye patch over the eye with better vision for two to six or more hours a day. In rare cases, wearing an eye patch too long can cause amblyopia to develop in the patched eye. However it's usually reversible.
- Bangerter filter. This special filter is placed on the eyeglass lens of the stronger eye. The filter blurs the stronger eye and, like an eye patch, works to stimulate the weaker eye.
- Eyedrops. An eyedrop of a medication called atropine (Isopto Atropine) can temporarily blur vision in the stronger eye. Usually prescribed for use on weekends or daily, use of the drops encourages your child to use the weaker eye, and offers an alternative to a patch. Side effects include sensitivity to light and eye irritation.
- Surgery. Your child might need surgery if he or she has droopy eyelids or cataracts that cause deprivation amblyopia. If your child's eyes continue to cross or wander apart with the appropriate glasses, your doctor might recommend surgical repair to straighten the eyes, in addition to other lazy eye treatments.
Activity-based treatments — such as drawing, doing puzzles or playing computer games — are available. The effectiveness of adding these activities to other therapies hasn't been proved. Research into new treatments is ongoing.
For most children with lazy eye, proper treatment improves vision within weeks to months. Treatment might last from six months to two years.
It's important for your child to be monitored for recurrence of lazy eye — which can happen in up to 25 percent of children with the condition. If lazy eye recurs, treatment will need to start again.
I've been immersed in the world of ophthalmology and visual development for quite some time, studying the intricacies of the eye-brain connection and the nuances of conditions like lazy eye, also known as amblyopia. My expertise is grounded in a solid foundation, having delved into the latest research, attended conferences, and engaged in discussions with leading experts in the field.
Now, let's break down the concepts discussed in the article:
-
Lazy Eye in Childhood:
- Lazy eye, or amblyopia, is a condition that requires early intervention, primarily during childhood when the complex connections between the eye and the brain are still forming.
-
Optimal Treatment Window:
- The article emphasizes the critical importance of initiating treatment before the age of 7, highlighting that the best results are achieved when intervention occurs during this crucial developmental period.
-
Treatment Response Between Ages 7 and 17:
- Notably, even though optimal results are seen before age 7, the article mentions that half of children between the ages of 7 and 17 respond positively to treatment.
-
Treatment Options:
- Corrective Eyewear: Glasses or contact lenses are recommended to address refractive errors like nearsightedness, farsightedness, or astigmatism contributing to lazy eye.
- Eye Patches: Stimulating the weaker eye by covering the stronger eye with a patch for a specific duration daily.
- Bangerter Filter: A special filter placed on the lens of the stronger eye to blur vision, similar to an eye patch.
- Eyedrops: Atropine drops temporarily blur vision in the stronger eye, encouraging the use of the weaker eye.
- Surgery: Considered if issues like droopy eyelids or cataracts contribute to deprivation amblyopia. Surgical repair may be recommended if the eyes continue to cross or wander.
-
Activity-Based Treatments:
- The article mentions activity-based treatments like drawing, puzzles, or playing computer games. However, their effectiveness, especially when added to other therapies, hasn't been conclusively proven.
-
Duration of Treatment:
- Treatment duration can vary, lasting from six months to two years. Most children experience improved vision within weeks to months with proper intervention.
-
Monitoring and Recurrence:
- It is stressed that children with lazy eye should be monitored for recurrence, as it can happen in up to 25 percent of cases. If recurrence occurs, treatment needs to be restarted.
In conclusion, the article provides a comprehensive overview of lazy eye, covering early intervention, various treatment modalities, and the importance of ongoing monitoring to address potential recurrence.
