Abstract Details

Purpose:

To evaluate incidence of dual platelet inhibition in cases of grade IV retrobulbar hematoma following retro- or parabulbar anesthesia during catarat surgery

Setting:

University eye clinic, retrospective study

Methods:

Overall, 141.212 emergency contacts between January 2007 and May 2012 were screened. Inclusion criteria consisted of retrobulbar hematoma with increase of IOP (grade IV hematoma) following retro- or parabulbar anesthesia within one week after cataract surgery. All cases identified were screened for presence of dual platelet inhibition, concomitant diseases, and possible additional risk factors.

Results:

Overall, three cases were identified. All of the cases presented inihibition of platelets or anticoagulative treatment. In none of the patients this treatment was discontinued during cataract surgery. None of the cases presented singular platelet inihibition, however the majority of patients presented with dual platelet inhibition (n=2). Anti-coagulative treatment was present in one case with delayed onset. Development of visual acuity (VA) after incidence of retrobulbar hematoma was poor in all patients.

Conclusions:

Grade IV retrobulbar hematoma seems to be an infrequent complication after retro- or parabulbar anethesia. Dual platelet inhibition is present in the vast majority of these patients. As the development of VA is poor in all cases, we strongly recommend catract surgery in topic anethesia in patients with dual platelet inhibition.
