Convergence Insufficiency (CI) is a syndrome characterized by a decreased ability to converge the eyes and maintain binocular fusion while focusing on a near target. CI is usually accompanied by a reduced near point of convergence (NPC), decreased convergence amplitudes or an exodeviation (usually > 10 prism diopters) at near.

2024年11月15日 · When your eyes can’t align in this way, you have convergence insufficiency (CI). The condition means you might find it hard to focus your eyes when you read, play video games, or work...

2024年10月23日 · In simple terms, Convergence Insufficiency (CI) is like a teamwork problem between your eyes. It's a common eye condition where your eyes struggle to work together smoothly when you're focusing on something close-up, like a book, phone, or computer screen.

Convergence insufficiency (CI) is a common, yet not frequently diagnosed eye coordination problem in which the eyes drift outward when reading or doing close work. Convergence insufficiency (CI) is caused by a simple “lack of proper communication” between the nerves and the muscles that control eye movements.

2023年7月18日 · Convergence insufficiency (CI) is a binocular vision disorder characterized by difficulty maintaining fusion while looking at a near target due to a tendency of the eyes to drift outwards. Commonly associated symptoms of CI include asthenopia (eye strain), diplopia, headaches, blurred vision, movement of print while reading, and difficulty with ...

Convergence insufficiency occurs when the eyes are unable to converge, or work together to focus on a near object. Children with CI must use additional effort to focus on reading, and other near vision tasks, in order to maintain focus for an extended period of time.

2024年1月9日 · Convergence Insufficiency (CI) is an eye coordination problem that affects binocular vision—the ability of both eyes to work together seamlessly. CI happens when the eyes drift inward when performing close or near work, resulting in double or blurred vision.

Convergence insufficiency is a binocular vision condition that affects near vision and eye muscle coordination. This condition occurs when the eyes are unable to effectively work together to focus on a near object. As a result, additional effort is needed …

2009年9月9日 · Convergence insufficiency (CI) is one of the most common binocular vision disorders that is encountered in optometry. It is a condition that was first described by Von Graefe in 1855 and has been the focus of many studies since then.

Convergence Insufficiency (CI) is a common binocular (two-eyed) vision disorder in which the eyes do not work at near easily. An eye teaming problem in which the eyes have a strong tendency to drift outward when reading or doing close work (exophoria at near). If the eyes do drift out, the person is likely to have double vision.
