If double vision is left untreated, it may worsen, cause blurred vision, and lead to strabismus, amblyopia, and so on. If binocular diplopia is left untreated, diplopia will be aggravated, resulting in monocular suppression, leading to vision loss, and in the long run, it will lead to strabismus and amblyopia, which will not only affect your normal life but also affect your aesthetics. Diplopia can be caused by many reasons, such as congenital abnormal development of extraocular muscles, nerve paralysis, traumatic injury to the eye resulting in muscle entrapment, intraocular or intracranial space causing diplopia, etc. If the cause is not found and treated in time, the diplopia will worsen. If the cause is not found and treated in time, the condition may worsen. Untreated diplopia may aggravate the symptoms and cause complications. When diplopia is detected, it is important to go to the hospital in time and follow the doctor’s instructions to control the condition and avoid deterioration.
