______ is a binocular vision disorder similar to Convergence Insufficiency except it is primarily characterized by an accommodative insufficiency with CI characteristics.

______ is a binocular vision disorder similar to Convergence Insufficiency except it is primarily characterized by an accommodative insufficiency with CI characteristics.

• A. Pseudo-convergence insufficiency
• B. Convergence insufficiency
• C. Divergence insufficiency
• D. Accommodative insufficiency

Answer: (A)

Accommodative weakness can masquerade as a convergence problem. Pseudo-convergence insufficiency is a binocular vision condition where the signs and symptoms resemble convergence insufficiency, but the primary deficit is accommodative insufficiency rather than a true vergence disorder. Patients often report near-vision difficulties and headaches, and may show CI-like signs such as near exophoria or trouble sustaining near tasks, yet the vergence system itself tests relatively normal. The crucial point is that addressing accommodation helps the problem: giving plus lenses for near or engaging in accommodation-focused therapy reduces the CI-like symptoms because it lowers the demand on accommodation and, via the accommodation-vergence link, reduces the erroneous convergence effort. In true convergence insufficiency the issue is the vergence system, so improving accommodation wouldn’t produce the same relief. Divergence issues or pure accommodative insufficiency without CI-type signs wouldn’t fit the described pattern.
