Binocular retinal birefringence scanning may be able to identify, already in very young children, amblyopia that is associated with strabismus, microstrabismus, or reduced fixation accuracy. Diagnosis and treatment of amblyopia as early as possible is necessary to keep the vision loss to a minimum. Screening for amblyopia is recommended in all people between three and five years of age. Treatment
Treatment of strabismic or anisometropic amblyopia consists of correcting the optical deficit (wearing the necessary spectacle prescription) and often forcing use of the amblyopic eye, by patching the good eye, or instilling topical atropine in the good eye, or both. : 130  Atropine appears to result in similar outcomes to patching. If there is overpatching or overpenalizing the good eye when treating amblyopia, "reverse amblyopia" can result. Eye patching is usually done on a part-time schedule of about 4–6 hours a day. Treatment is continued as long as vision improves. It is not worthwhile continuing to patch for more than 6 months if no improvement continues.Deprivation amblyopia is treated by removing the opacity as soon as possible followed by patching or penalizing the good eye to encourage the use of the amblyopic eye. The earlier the treatment is initiated, the easier and faster the treatment is and the less psychologically damaging. Also, the chance of achieving 20/20 vision is greater if treatment is initiated early.One of the German public health insurance providers, Barmer, has changed its policy to cover, as of 1 April 2014, the cost of software for amblyopic children whose condition did not improve through patching.
Frequent exposure to victimization or bullying was related to high risks of depression, ideation and suicide attempts compared to those not involved in bullying. Nicotine dependence is also associated with depression, anxiety, and poor dieting, mostly in young men. Although causal direction has not been established, involvement in any sex or drug use is cause for concern. Children who develop major depression are more likely to have a family history of the disorder (often a parent who experienced depression at an early age) than patients with adolescent- or adult-onset depression. Adolescents with depression are also likely to have a family history of depression, though the correlation is not as high as it is for children. Comorbidity
There is also a substantial comorbidity rate with depression in children with anxiety disorder, conduct disorder, and impaired social functioning. Particularly, there is a high comorbidity rate with anxiety, ranging from 15.9% to 75%. Conduct disorders also have a significant comorbidity with depression in children and adolescents with a rate of 23% in one longitudinal study. Beyond other clinical disorders, there is also an association between depression in childhood, poor psychosocial and academic outcomes, as well as a higher risk for substance abuse and suicide.The prevalence of psychiatric comorbidities during adolescence may vary by race and ethnicity. Social causes
Adolescents are engaged in a search for identity and meaning in their lives. They have also been regarded as a unique group with a wide range of difficulties and problems in their transition to adulthood.
