Final answer:
A child with a recent onset of noncomitant deviation may experience symptoms like double vision, difficulty with eye movements, eye strain, and headaches, along with behavioral compensations such as tilting the head or squinting. Diagnosis and treatment involve a comprehensive eye exam and could include glasses, prisms, vision therapy, or surgery.
Step-by-step explanation:
Noncomitant Deviation in Children
If a child presents with a recent onset of noncomitant deviation, one can expect various signs and symptoms associated with this eye condition. Noncomitant deviation refers to a misalignment of the eyes that varies with gaze direction. The symptoms may include double vision (diplopia), difficulty with eye movements, eye strain, and headaches because of the extra effort required to focus. A child may also exhibit physical signs such as tilting the head or squinting in attempts to compensate for the misalignment and improve vision. In an effort to fuse the images seen by each eye, a child might also close or cover one eye. The appearance of the eyes may commonly lead to a visible misalignment, which can be intermittent or constant and might only be obvious when the child looks in specific directions.
It is important to evaluate and diagnose the underlying cause of the noncomitant deviation, as it can have several etiologies, including nerve palsies, trauma, or systemic diseases. An eye care professional can provide a comprehensive eye examination to determine the exact nature of the deviation and the appropriate treatment. Treatment can range from glasses or prisms to align the visual axes, to vision therapy, or potentially surgery depending on the underlying cause and severity of the deviation.
