Evaluation of ocular perforation during retrobulbar block using high-resolution spectral domain–optical coherence tomography and optical coherence tomography angiography:

Introduction:This article reports a case of ocular perforation during a retrobulbar block in a patient who underwent scleral buckle for retinal detachment.Methods:Sterile air was immediately injected into the vitreous cavity to restore intraocular pressure and the scleral buckle operation was quickly finished. One week later, a laser retinopexy was performed on the two retinal holes that were outside the foveal area. After 6 months, spectral domain–optical coherence tomography and optical coherence tomography angiography were performed on the perforated wall centered on the exit hole area.Results:The visual acuity was maintained 20/20 and the retina was totally attached. Spectral domain–optical coherence tomography showed a localized interruption of inner retina, retinal pigment epithelium, and choroid, with a higher posterior reflectivity in correspondence with the sclera. Optical coherence tomography angiography was able to detect atrophic alterations in the choroidal slab with a good visualization of l...
