The retina tears in this location and the watery component of the jelly (the part that has liquefied) can pass thought the tear under the retina and the retina starts coming away (detaching) from the back wall of the eye. Most retinal detachments occur when the jelly (vitreous) that occupies the main eye cavity starts to liquefy and pulls away from the back of the eye but does not want to “let go” of a particular area of the retina (photographic film lining the back wall of the eye). What is the surgical treatment of retinal detachment? It is best therefore to treat the retinal tear before the retina detaches with laser but if the retina starts to detach it is still important to treat as soon as possible as the prognosis for obtaining good vision following surgery if much better if caught at an early stage and in particular if surgery takes place before the central retina (macula) detaches. If left untreated the whole retina can detach results in very poor vision. ![]() The blurring usually therefore comes on after a sudden onset of flashes and floaters and develops over hours or days as a dark shadow you cannot see through and appears initially from the side or periphery of the vision and as the detachment spreads towards the centre of the retina (macula) so the blurred patch increases towards the centre of the vision. When the retina starts “detaching” from the back wall of the eye it comes away from its main blood supply and therefore stops functioning and the detached retina results in a blurred patch in the vision. If left untreated the tear in the retina usually progresses into a retinal detachment as the watery component of the jelly in the main eye cavity can get underneath the retina through the tear and the retina starts to come away from the back wall of the eye. If a retinal tear is diagnosed quickly then treatment can be applied as an out-patients procedure to “spot weld” it in place with laser. Patients who are short sighted are more prone to this occurring as their jelly degenerates at a younger age that normal sighted people and they are also more likely to have abnormal adhesion between the retina and jelly. These patients usually notice a sudden shower of new floaters associated with flashing light sensations as the retina tears. This jelly gradually degenerates with the passage of time into a more watery consistency and eventually when sufficient water has accumulated in the jelly the remaining jelly that is up against the retina separates from it and in most people collapses down into smaller lumps causing some floaters in the vision which usually improve as they float down to the bottom of the eye with gravity.Ī small number of patients however have abnormal adhesion or stickiness between the remaining jelly and the retina in places and as the jelly pulls away it does not want to “let go” of the retina in this position and pulls sufficiently hard to tears the retina. Between the two in the “body” of the camera is a clear jelly called vitreous. The eye is like a camera with the lenses at the front and the photographic film (retina) at the back. ![]()
