Cataract surgery, especially if you have complications, increasing the risk of a retinal detachment. Cataracts are cloudy areas (opacities) are formed on the lens. Following the introduction of extracapsular surgery (extra capsular surgery), a modern method which is now used almost exclusively for the removal of cataracts, the risk of retinal detachment has been further reduced. In extracapsular cataract surgery, part of the lens capsule was left in place so that the vitreous gel is not disrupted. Phacoemulsification is a type of extracapsular cataract surgery using an ultrasonic instrument is very high speed to break up and suck out the foggy lens of the eye. Capsules can be left inside the eye becomes cloudy then, requires the opening of the capsule by using a laser. Opening the capsule increases the risk of retinal detachment.
In intracapsular cataract surgery (intracapsular cataract surgery), the main operating method used from 1965 to 1990, the entire lens is removed. Capsule on the back of the lens, therefore, no longer there to hold the vitreous gel in place. As a consequence, the vitreous gel to move forward, and the retina had an increased withdrawal or appeal to the retina from the vitreous, which resulted in tearing of the retina. Now, if the capsule rupture, which can be a complication of extracapsular cataract surgery time, the vitreous gel in the same way to move forward and pull on the retina. This circuit can lead to a retinal tear and release, especially in the first year after surgery.
Other factors related to with Retinal Detachment
- Blunt injuries, such as hit a tennis ball or a fist, or a stab wound by a sharp object in the eye can cause retinal detachment.
- A family history of a release of the retina that naturally does not come from the wound seems to indicate on a genetic predisposition to develop retinal detachments.
- As much as 5% of patients who experienced the release of the retina in one eye that is not of a wound, a release on the other eye happened afterwards. Therefore, the second eye of patients with a retinal detachment should be examined carefully and strictly followed, by both patients and ophthalmologists (ophthalmologist).
- Diabetes can cause retinal detachment caused by traction on the retina itself, without a tear. Because the abnormal blood vessels and scar tissue on the surface of the retina in some patients with diabetes, the retina can be lifted (detached) from the back of the eye. In addition, blood vessels may bleed into the vitreous gel. This release may involve the edge of the area or areas of the central retina.
