Retina is a part of the eye. This rather complex tissue actually covers the inner surface of the back of the eye. The role of the retina is to receive the light images. The process of focusing of these images is helped by two other eye organs called the cornea and the lens. After the light has reached the retina, a specific biochemical change occurs and the electrical impulses that are formed are further distributed via optic nerve into the part of the brain that is in charge with vision. The brain finally defines what we really see.
Retina is formed by two types of cells, the rods and the cones. The rods are in charge of night vision while the role of the cones is to sharpen the eye sight. In the very center of retina there is a macula. Peripheral part of retina which includes everything apart from macula is rather important as it helps us to notice and see the objects that are around us. This way retina helps us to move without bumping into people and surrounding things. On the other hand macula is important as it is in charge with more specific vision that is essential for reading and so on. This organ is as any other organ in the body well supplied with blood due to retinal arteries and veins.
Retinal detachment is a condition in which retina disconnects from the layer it is lying on. The majority of detachments happen due to the breaks or tears of the retina. The vitreous gel is what keeps retina lying on the tissues below it. Now, if vitreous gel loosens the retina can detach. The problem starts when a part of retina has already detached and the tear is big enough to allow the entrance of vitreous gel. This way the gel may enter the tear and lead to further retinal detachment. In case that this condition continues the whole surface of retina can end up detached. In certain cases the tear is followed by the bleeding from retina blood vessels.
Possible Complications of Retinal Detachment Surgery
The goal of the surgery is to find all the breaks on the retina and to fix them. There are several procedures that can be performed in this case.
Some patients face no complications at all. Others may complain about slight discomfort and watering of the operated eye. The eye may be red and with edemas. Itchiness can be present for certain period of time. Luckily, all the previous problems can be easily solved with eye drops.
In small number of patients blurred vision can persist for several months. This condition requires new spectacles with changed diopter.
In case of scleral buckle surgery one may suffer from double vision. Glaucoma, which is the condition that features with increased pressure within the eye, is another possible complication.
Bleeding can affect different parts of the eye. The blood can collect into the vitreous, in the retina or behind it. The worst complications include cataract and dropping of the eyelid. They require additional surgical procedure. And finally, if the patient is not administered proper antibiotics even infection can occur.
