Use of occluders in ophthalmology


An occlusion patch or occluders (eyecups) is a medical device that prevents moisture, air and microorganisms from entering the wound from the external environment.

In this case we will talk about therapeutic occluders that are used for various pathologies such as (amblyopia, strabismus, diplopia, photophobia, etc.), as well as for aesthetic purposes.

Under what circumstances do doctors recommend the use of occluding dressings?

For example: 

Amblyopia means lazy eye. In childhood amblyopia occluders are very often used for treatment, as the pathogenesis of amblyopia is based on the insufficient functioning of the eye during development, as a result of which the eye becomes lazy, which can subsequently lead to a decrease in visual acuity.  In these cases, if the better seeing eye is closed, the worse seeing eye, i.e. the lazy eye, will start working, receiving information from the outside world individually, thus increasing visual acuity.

Diplopia is the perception of two images of the same object, or a double image of an object.  It can be monocular and binocular.

In binocular diplopia it is very difficult to orient in space, it is difficult to distinguish (distance, nearness, depth of stairs, take objects, etc.), in such cases it helps to suppress one of the images with the help of occlusive bandage. If the patient closes one eye, one of the objects disappears. Diplopia is usually a symptom of an underlying disease such as traumatic brain injury, brain tumors, postoperative manifestations.

Also, occluders are used for aesthetic or cosmetic purposes, when the patient wants to hide visually his eye due to various reasons such as anophthalmos (absence of an eye or underdevelopment of the eye), microphthalmos (small eye), corneal opacity, or pronounced photophobia, etc…

There are types of occluders.

Silicone – on a suction cup, not expensive enough and not aesthetically pleasing, traumatic, scratches can leave on the lens and does not completely cover the peripheral part of vision. 

Patches – occluder patch, around the eye is well glued to the skin, but when removed can cause irritation, as well as painful sensations, does not provide ventilation of the eye, which is important in the process of vision, thus can develop various inflammation. Thus, patches have their disadvantages in the treatment of amblyopia in children, as they are financially expensive, not aesthetically pleasing, and can get wet if the child cries.  Children in patches may feel self-compromised due to the constant occlusion.

The most comfortable and optimal are cloth occluders.

If we look at MokVok occluders, they have all the qualities that are necessary for the eye. 

In addition, they are available with different patterns that children do not perceive as a medical device, but feel like toys and do not resist when closing the eye. At the same time the fabric is very pleasant.
