Dynamic squint is a term used in ophthalmology to describe an eye condition where one eye deviates from its normal position when the person is looking at a distant target. The term is spelled phonetically as /daɪˈnæmɪk skwɪnt/, which means that the first syllable is pronounced as "dai" with a long "i" sound, the second syllable starts with a short "a" sound, and the final syllable has a long "i" sound followed by a short "u" sound. The IPA transcription helps to clarify the pronunciation of this technical term.
Dynamic squint refers to an ophthalmological condition characterized by the involuntary misalignment of the eyes during intentional eye movements, resulting in a temporary double vision. Also known as divergence excess esotropia, dynamic squint occurs when the muscles responsible for controlling eye movements fail to work harmoniously, causing the eyes to deviate inwardly or outwardly from their normal alignment.
This dynamic condition is typically experienced by individuals who have a tendency for their eye muscles to overcorrect or undercorrect their intended eye movements, leading to a misalignment of the eyes. During dynamic squint, the misalignment is exacerbated during active eye movements, such as when focusing on a moving object or switching between near and distant vision. This dynamic aspect distinguishes dynamic squint from static squint where the misalignment persists regardless of eye movement.
Symptoms of dynamic squint commonly include diplopia (double vision), eye strain, and headaches, especially during activities that involve visual tracking or focusing. Treatment options for dynamic squint may include wearing corrective eyeglasses or contact lenses, vision therapy exercises aimed at improving eye muscle coordination, or in more severe cases, surgical intervention to rebalance the eye muscles and align the eyes correctly.
Early detection and management of dynamic squint are crucial to prevent complications and maintain clear and comfortable vision. Regular eye examinations by an ophthalmologist or optometrist are recommended, particularly for those exhibiting symptoms associated with dynamic squint.
