| Summary: |
Purpose: Present
own experience in evaluating anatomical results of pars
plana vitrectomy in eyes filled with silicone oil using
Optical Coherent Tomography technique.
Materials and Methods: OCT (SOCT-HR Copernicus
instrument) examination was performed in patients one to
six months after pars plana vitrectomy with silicone oil
tamponade. Surgery was carried out due to retinal
detachment. In all cases satisfactory anatomical result
was achieved and retina reattached, confirmed in
biomicroscopy.
Results: In almost all patients high-resolution
scans could be obtained and retinal layers visualized.
In majority of cases regular, normal picture of the
retina correlated with satisfactory functional effects
of the surgery. However in cases with low visual acuity
despite good anatomical state (reattached retina) we
found pathologies that could not be observed in clinical
slit-lamp examination such as thickening of retinal
layers, perfluorocarbon liquid in front of the retina or
macular oedema. Poor imaging of retina due to
pathologies such as cataract, posterior capsule
opacification or oil emulsification were main
limitations of this method.
Conclusions: OCT is a new, diagnostic,
non-invasive technique that can be easily performed in
eyes filled with silicone oil after pars plana
vitrectomy. In many cases it enables to gain more
information about clinical state and explain not
satisfactory function despite good anatomical results. |
