If the amblyopia in the left eye has a visual acuity of only 0.3, whether it can be cured or not depends on the timing of the discovery of the cause of the disease, etc. If the discovery is timely and the training is proper, it is possible to be cured.
For amblyopia caused by various reasons, in order to achieve complete cure or obvious visual acuity improvement, it is necessary to find out the cause of monocular amblyopia as early as possible and deal with it. If we can find out the cause as early as possible and carry out corrections or treatments, we can achieve better therapeutic effects, and we can cure amblyopia of 0.3 in the left eye and developmental delays.
In addition to treating the causes of amblyopia and delayed development of vision, a longer period of amblyopia training, monocular suppression, follow-up visits, and review, etc. For adolescents or adults with amblyopia detected at a late stage, the effect of treatment is very limited, and basically it is very difficult to improve the visual acuity of 0.3 significantly.
It is recommended that children of the appropriate age should be screened regularly for visual acuity, so that delayed visual development and amblyopia can be detected and treated in a timely manner.
