To study macular hole closure after re-vitrectomy with silicone oil endotamponade using high resolution fourier domain Optical Coherence Tomography (OCT).
9 eyes of 9 patients were examined with fourier domain OCT (Cirrus OCT, Zeiss-Humphrey) after vitrectomy with silicone oil for persistent idiopathic macular holes. Macular morphology under silicone oil as well as after silicone oil removal was analyzed. Mean follow-up was 49 days after oil removal.
In 4 eyes, the macular hole was closed under silicone oil and remained closed after oil removal. In all cases neuroretinal tissue was visible throughout the center of the macula. In 4 eyes, a persistent macular hole with a retinal defect was present and the hole reopened after oil removal. In 1 eye, macular hole closure was only partial and asymmetric reopening after oil removal could be observed.
High resolution fourier domain OCT proved to be superior to standard time domain OCT in delineating macular structures under silicone oil endotamponade. Our limited study suggests that the aspect of macular holes under silicone oil determines the prognosis after oil removal. Thus, further measures (e.g. re-peeling or the use of adjunctive agents) may be taken in eyes with a persistent macular hole under silicone oil endotamponade.
