The retina has 10 layers. In case of retina detachment the inner 9 layers are separated from the pigment epithelium. It can be caused for example trauma, inflammation, glaucoma. There is a new tool in opthalmic diagnostic the optical coherence tomography. With these device we are able to examine all of the layer of the retina almost in histological level.
Our goal to show the importance of optical coherence tomography (OCT) in the diagnostic of retinal detachment.
In our study we used Fourier domain OCT. The examination was performed in anaesthesia. We examined 12 dogs. The age of dogs was between 1 and 15 years old. Before OCT examination we photographed the retina with fundus camera in all cases.
In some cases in the fundus camera pictures we cannot see the retinal detachment although the detachment and fluid between the layers of the retina was easily visible with OCT. With the help of OCT we can detect fine changes. We can accurately determine the size of the detachment.
With OCT we can make much more detailed examination. So fine lesions can be detected which are not visible with fundus camera or ophthalmoscope. We can record all of the examination so we can follow the progression of the disease.
