“…Various adverse effects and complications arising from retrobulbar block have been described in the literature, including perforation of the eye bulb, conjunctival hemorrhage, chemosis, corneal ulceration, damage to the optic nerve (GILLART; DUALÉ; CURT, 2002;KUMAR;DOWD, 2008), respiratory arrest (RUUSUVAARA; SETÄLÄ; TARKKANEN, 1988), arterio-venous retinal occlusion (TORRES et al, 2005;KUMAR;DOWD, 2008), deafness (GEORGE; HACKETT, 2005), blindness and paralysis of the extraocular muscles (CHINCHURRETA-CAPOTE et al, 2006;KUMAR;DOWD, 2008). Chemosis and corneal ulceration were observed in this study in low ocurrence and they did not hamper blocking or interfere with its effect.…”

“…Our patient experienced a sudden visual loss due to a combined retinal vein occlusion (RVO) and retinal artery occlusion (RAO). The etiologies may be mechanical compression of the optic nerve, such as inadvertent retrobulbar injection in the optic nerve sheath, optic nerve inflammation from systemic disease or orbital inflammatory pseudotumor 810. Additionally, systemic disorders may also cause combined RVO and RAO, such as protein C deficiency, systemic lupus erythematous, antiphospholipid syndrome, and PAX3 mutation with Waardenburg syndrome type 1 1113…”

“…O bloqueio retrobulbar pode ter como complicações hemorragias, perfuração do bulbo ocular, injeção intravenosa, danos ao nervo óptico, lesão dos músculos extraoculares e injeção do anestésico no espaço subaracnóide, podendo ocasionar parada respiratória ou convulsões (Accola, Bentley & Smith, 2006;Torres, Luchini, Weis, Frecceiro & Casella, 2005;Giuliano & Walsh, 2013). Entretanto, é utilizado um menor volume de solução anestésica quando comparado com a técnica extraconal, além de possuir ação mais rápida, pois entra em contato direto com estruturas nervosas (Otero & Portela, 2018).…”
