    Author: Vasavada D, Baskaran P, Ramakrishnan S.

    Abstract:
    Retrobulbar injection has been widely practiced as a technique of ocular anesthesia for many decades. Nevertheless, the technique is not free from complications. Vascular occlusion secondary to retrobulbar injection is rare but can be vision threatening. We report a case series of two such patients who presented with poor vision following retrobulbar injection. Fundus showed pale retina with cherry red spot suggestive of central retinal artery occlusion in case 1 and pale disc with sclerosed vessels and multiple superficial hemorrhages suggestive of a combined occlusion of retinal artery and vein in case 2. Optical coherence tomography (OCT) showed thickened inner retinal layers with intact outer retinal layers in case 1 and thinning in case 2. We conclude that retrobulbar injections can rarely be associated with dreadful vision-threatening complications like in our patients. We also report the role of OCT in assessing the prognosis following vascular occlusion.
