[OCT in macular holes].
The traditional Gass classification of macular holes can now be supplemented by additional and more detailed morphologic information obtained with optical coherence tomography (OCT). The perifoveal vitreous detachment and subsequent anterior foveal traction is considered to be the primary pathomechanism of macular hole formation. In cases of persistent traction on the fovea it may lead to foveal dehiscence. A possible explanation for intraretinal cyst formation may be secondary vitreous body fluid accumulation within the retina. A classification of macular holes based on additional information from OCT images is possible. Thus, OCT is a valuable tool for differential diagnosis of a pseudo macular hole versus macular hole, precise stage classification, therapy decision making process, outcome control after macular surgery, and prognosis prediction.
