Cover Test: what is it and how does it help identify hidden strabismus in children

Strabismus is a vision disorder in which the eyes cannot look in the same direction at the same time. Depending on the direction of deviation of the eye from the axis of vision, strabismus can be convergent or divergent. If left untreated, squint can lead to serious vision problems and even blindness.

The Cover Test is a simple method used to detect hidden strabismus in children. This test determines how the eyes work together when they focus on one object.

How is the Closing-Opening test performed?

The doctor administering the test will ask the child to look at an object, such as a toy or a letter on a card. The doctor will then cover one of the child's eyes with their palm for a few seconds while the child continues to look at the object with one eye. After this, the doctor will quickly remove his hand to check how the eyes react.

If the eye that was covered begins to move towards the nose in order to focus vision on the object, then this indicates that the child has convergent strabismus. If the eye begins to move in the opposite direction, then this indicates that the child has divergent strabismus.

Repeating the test with the other eye allows you to determine which eye is “lazy” and how severe the strabismus is.

How does the Closing-Opening test help detect hidden strabismus?

The Closing-Opening Test is one of the most effective methods for identifying hidden strabismus in children. This method can detect even mild strabismus, which may go undetected during a routine eye examination.

Identifying strabismus at an early age is very important because the sooner treatment begins, the greater the chance of full vision restoration. Treatment for strabismus may include wearing special glasses, doing eye exercises, and in some cases, surgery may be required.

In conclusion, the Closing-Opening test is a simple but effective method for identifying hidden strabismus in children. Regular eye exams and identifying strabismus early in life can help prevent serious vision problems in the future. If you suspect your child has strabismus, see your doctor for diagnosis and treatment.

The Cover Test (or also known as the Foster Test) is one of the most common methods for detecting hidden strabismus, which can cause vision problems and developmental disorders. This test is simple and non-invasive, which makes it especially attractive for use in pediatric ophthalmology.

The principle of the test is that the child looks at an object with one eye while the other eye is open. The doctor covers the other eye with his palm, after which the palm is removed. If the eye begins to move towards the nose to focus vision on the remaining open eye, then this indicates the presence of convergent strabismus; if the eye moves in the opposite direction, then this indicates divergent strabismus.

This test can be used to diagnose latent strabismus in the earliest stages, when other methods may be less effective. It can also help determine which type of strabismus a child has, which can be important for choosing the right treatment.

The Closing and Opening Test is a useful tool in pediatric ophthalmological practice and can be used both to diagnose latent forms of strabismus and to monitor treatment and treatment results. It is important to remember that this test does not replace a full ophthalmological examination and should only be used as an adjunct to other diagnostic methods.

The Cover test is a method for diagnosing latent forms of concomitant strabismus, thus it makes it possible to detect hidden forms associated with squinting eyes. This can be said about some other test methods, but this one in particular will help to recognize the presence of hidden parts of vision that would otherwise not be recognized.

Test method for hidden visual strabismus

It is carried out as follows: * The child should look as closely as possible somewhere with one eye, while at the same time the second eye remains open * At this time, the doctor closes one of the child’s eyes with a napkin or hand. At the moment when the napkin is removed, the child must fix his gaze on an object that was outside his field of vision before applying the technique * If, upon careful examination, the baby observes eye movements towards the nose while focusing on the other eye, then in this case you can safely declare that the newborn has conjoint strabismus.

If the baby's eye moves towards the ear, this indicates a divergence of focus

In what cases is the method prescribed? * When a baby has an asymmetrical development of the eyes - there is a deviation in one direction, transverse or vertical * When studying eyelid disorders resulting from paralysis or trigeminal neuritis. In addition, this technique can serve as a criterion for determining the degree of impairment and monitoring the process of vision restoration. What benefits will covering your baby's eyes have with a napkin? This will allow us to determine the main direction and type of eye pathology. After all, it is known that the right side requires higher fixation than the left. The more accurately the technique covers all sides of the lesion, the better the result is achieved in the treatment of the anomaly.
