Amblyopia SymptomsHow to Fix a Lazy Eye in Adults? Lazy eye is a condition in which one or both eyes have decreased vision caused by visual deprivation or abnormal binocular fusion. The lazy eye develops in early childhood; hence it is a disease of childhood. Once a lazy eye has developed it becomes almost impossible to reverse the condition in some cases, while timely recognition of the lazy eye by the parents of the child can give a good prognosis for the vision. As no organic cause can be determined by the examination, that is the reason why lazy eye disease remains undetected until late. There are some therapeutic procedures when followed in children can result in the best visual results. However, compliance is a keep factor for the best results. As the process of normalization is prolonged, many patients do not keep compliance which is a key factor in a poor outcome. Education of the parents is very important who is having a child with lazy eye or amblyopia. CLASSIFICATION OF LAZY EYE:The causes of amblyopia can be divided as followed Stimulus deprivation amblyopia:One of the most common cause of stimulus deprivation is congenital cataract, especially unilateral cataract is highly amblyogenic. Other common cause includes drooping of the upper lid up to the visual axis of the eye. Constant occlusion of one eye (> 1 week per year of age) due to any cause is very likely to develop amblyopia. Refractive error:Anisometropic amblyopia:This condition arises when the refractive power between the two eye is >1D. This is a highly amblyogenic stimulus. Ametropic amblyopia:When the symmetrical refractive error is >+5.0 DS or > -10.0 DS unilateral amblyopia may occur, if correction not done. Astigmatic/ meridional amblyopia:The relative risk of astigmatic amblyopic is increased if cylinder power is > 0.75 DC. Risk is more when there is difference in axis or if magnitude between two eyes is different. Strabismic amblyopia:Strabismic amblyopia is caused when one eye is preferred for fixation. If the process is alternating between the two eyes, then the risk is low. Pathophysiology of Lazy Eye:Retina:There is a reduction in spatial resolving power of the retinal cells. Lateral geniculate nucleus:In lazy eye there is reduction number of cells of all the six layers of the lateral geniculate nucleus. Visual cortex:There is reduction in the number of cortical cells. Clinical Features of Lazy eye:
There is an abnormality of contour interaction between the point of fixation and the adjacent objects. Visual acuity is better for single optotypes than multiple optotypes.
MANAGEMENT OF LAZY EYE:Exclude other causes:Other causes of decreased vision such as refractive error, cataract, tumors should be excluded. Remove obstacles to clear vision:Remove refractive error and perform cataract surgery for cataracts. Occlusion therapy (GOLD STANDARD):The amount of occlusion therapy depends on the age, severity, and cause of lazy eye. Steps:
This method is preserved for non-compliant or patients who show a failure to patching therapy Pharmacological:1% atropine drop is placed in the better eye to blur the vision for near. Optical:Image degradation is made in the better eye so that amblyopic has a competitive advantage. In this method under correction of the better eye is made with optical lenses. ADDITIONAL MANAGEMENT PRINCIPLES:
PREVENTION:
Can a Lazy eye be reversed ?Amblyopia can be reversed up to the age of 7-8 years, after this age it is usually permanent. It is the average age for the development of normal vision in the human eye, after this, no therapy or treatment can reverse the vision. What are the signs of amblyopia ?The signs of amblyopia include
What age does a lazy eye develop?Up to 6 years of age children are vulnerable to develop amblyopia. What if there is no response after 3 months of Patching therapy for children?If there is no improvement after 3 months, then consider the following
What is the best treatment for how to fix a lazy eye?In children below the age of 9 years, patching therapy is considered a gold standard. It will force the lazy eye to do it function more effectively while the patch is placed on the better eye. Can lazy eye worsen?If left untreated the lazy may get worsen over time. The brain gradually stops to pick signals from the lazy eye and it can render as a blind eye. Can lazy eye be corrected in adults?yes For Deatil Click Here
