Blindness following cosmetic blepharoplasty—a review

Neuropatia óptica isquêmica posterior como complicação pós-cirurgia de blefaroplastia

“…A complicação de blefaroplastia que causa perda visual com fundo de olho normal, defeito pupilar aferente e perda difusa da sensibilidade central com preservação relativa do setor nasal inferior é a NOIP (9)(10)(11)(12)(13)(14) . A NOIP pós-blefaroplastia está associada a alterações orbitárias como hemorragias (12)(13)(14) , no caso a ressonância magnética era normal, levamos então a considerar o uso do anestésico local com vaso constritor, o qual promove a isquemia por comprometer as artéri-as principais responsáveis pela irrigação da parte orbitária do nervo óptico. Em contato com o cirurgião plástico fomos informados da não utilização de vasoconstritor na anestesia local e que a reoperação foi realizada para remoção de coágulo da pálpebra inferior sem acesso a cavidade orbitária.…”

Blindness after cosmetic blepharoplasty: case report

“…Ischemia unrelated to intraorbital bleeding is spasm within the concerned vessels and this has emerged. Theoretically it could be caused by pulling on the fat pedicles or by the use of vasopressor agents such as adrenaline in the local anesthetic infiltrates, or by the action of vasoactive agents released from extravasated blood (9) . Clinically the signs and symptoms of orbital hemorrhage are an acute onset of orbital pain with an increased intraorbital pressure manifested by proptosis, lid ecchymosis, increased intraocular pressure, limited extraocular muscle movement, and a dilated, unresponsive pupil.…”

“…Clinically the signs and symptoms of orbital hemorrhage are an acute onset of orbital pain with an increased intraorbital pressure manifested by proptosis, lid ecchymosis, increased intraocular pressure, limited extraocular muscle movement, and a dilated, unresponsive pupil. Visual acuity is usually reduced but can range from 6/6 to no light perception (9) . In our case, there was marked subconjunctival hemorrhage associated with marked edema or congestion of the intraorbital fat.…”

Lower Eyelid Blepharoplasty

“…8,9 Factors that influence bleeding tendencies should therefore be identified and controlled before surgery. 10 Ingestion of aspirin, nonsteroidal antiinflammatory drugs (NSAIDS), antiarthritics, cortisone preparations, and vitamin E should be withheld for at least 14 days before surgery because of qualitative effects on platelet function.…”
