Since a vitreous separation can create a retinal tear, followed by a retinal detachment, we take these very seriously. It is the process of the vitreous separation that carries the risk of inducing a retinal tear. Once the vitreous has completely separated, there is very little reason for concern. Therefore, it is very important to carefully evaluate the retina when the vitreous separation begins, and again, about a month later. The examination technique requires the use of a headlight worn by your ophthalmologist, and the use of scleral depression.
Gentle pressure is applied to the eyelids so that the peripheral or side retina can be visualized.
This is the area where retinal tears are most frequently located. Occasionally, a special type of examination contact lens may be temporarily applied to the eye after it is numbed with eyedrops. During this time, it is very important for the patient to be aware of worsening floaters, increasing light flashes or a shadow or a curtain in the vision. These are all signs that the retina may be detaching, and an emergency visit is essential. In most cases, a vitreous separation is nothing more than a nuisance.
