Squint
Squint, also referred to as strabismus, is a condition in which both eyes do not look in the same direction. Squints are most common in young children, accounting for about one out of every twenty. Adults and even older children can develop squints.
Squint Signs and Symptoms
- The basic symptom of a squint is an unstraightened eye.
- When the misalignment is large and visible, your brain makes almost no attempt to realign the eye, and the sensations are minimal.
- Headaches and eyestrain are more common when the misalignment is less severe or not continuous.
- Reading weariness, shaky or unstable eyesight, and an inability to read comfortably are all possible symptoms.
There are Different types of Squint:
- Esotropias: It is the medical name for convergent squint where one of the two eyes turns towards the nose.
- Exotropias: It is the medical name for divergent squint where one of the two eyes turns outwards.
- Hypotropias and hypertropias: Both terms refer to vertical squint where one eye is lower (hypotropias) and the other is higher (hypertropias) than the fellow eye.
There are a number of squints in each of these three groups, which have their own individual treatments and characteristics:
Paralytic Squints: There are three nerves that send signals to the eye muscles, these are basically the third, fourth, and sixth cranial nerves. Any damage to these nerves may result in poor blood supply to the nerves, pressure on the head, or nerve injuries that will cause limited eye movements and a squint.
Risk Factor for Convergent Squint
- Refractive error – hypermetropia
- History of the family
- Disorders of the genome
- Hyperthyroidism
- diseases of the nervous system
- Birth before the due date
Treatment for Convergent Squint
- Surgery is required for congenital or infantile esotropia.
- Refractive esotropia necessitates the use of glasses, and some people may require bifocals.
- If the MRI brain scan is normal, surgery may be required for acute onset esotropia.
- Depending on the type of incomitant esotropia, surgery may be required. Botox injections or prism spectacles
Risks of Convergent Squint
- Blindness in one or both eyes
- issues with binocular vision
- Loss of 3D vision; dual vision
