  • Hyphema after Peribulbar Anesthesia for cataract surgery in Fuchs' heterochromic iridocyclitis.
    Ocular Immunology and Inflammation, 1998
    Co-Authors: Rubens Belfort, Christina Muccioli
    Abstract:

    Purpose: To describe an unusual ocular sign in one patient with Fuchs' heterochromic iridocyclitis at cataract surgery. Methods: We describe a patient with Fuchs' heterochromic iridocyclitis and cataract who developed a 1 mm hyphema observed two minutes after Peribulbar Anesthesia for cataract surgery. Results: The patient was found to have an equivalent of the Amsler-Verrey sign. It appeared after Peribulbar Anesthesia and before any instrument touched the globe. It did not interfere with surgery and disappeared completely by day 2. Conclusion: The appearance of a hyphema after Peribulbar Anesthesia in Fuchs' heterochromic iridocyclitis is an unusual sign that may have the same pathophysiology as the Amsler-Verrey sign.

  • central retinal artery occlusion after Peribulbar Anesthesia
    Journal of Cataract and Refractive Surgery, 2004
    Co-Authors: Albert Vinerovsky, Eitan Z Rath, Uri Rehany, Shimon Rumelt
    Abstract:

    We describe the development of central retinal artery occlusion (CRAO) in 2 patients after Peribulbar (periconal) Anesthesia during uneventful phacoemulsification. Although Peribulbar Anesthesia avoids direct optic-nerve injury, indirect injury presenting as CRAO may occur from vasospasm in response to the injection.

  • risks and sequelae of scleral perforation during Peribulbar or retrobulbar Anesthesia
    Journal of Cataract and Refractive Surgery, 2010
    Co-Authors: Wolfgang Schrader, Marc Schargus, Evelin Schneider, Tatjana Josifova
    Abstract:

    Purpose To assess the risk for and circumstances of serious complications during Peribulbar and retrobulbar Anesthesia. Setting University eye departments, Freiburg and Wurzburg, Germany, and Skopje, Macedonia. Methods This retrospective analysis comprised patients who received secondary care for complications of inadvertent globe perforation during Peribulbar or retrobulbar injections over a 17-year period. Results The review identified 9 inadvertent globe perforations that led to a variety of complications, ranging from subretinal hemorrhage to a globe rupture. Two cases were minor (subretinal hemorrhage with spontaneous resorption and retinal break requiring photocoagulation). All other cases required 1 or more vitrectomies to resolve intraocular hemorrhage and retinal detachment. Most cases still had significant functional impairment after treatment. Two of the 9 eyes regained reading ability, 1 eye maintained no light perception acuity, and 6 eyes had ambulatory vision only. Conclusions Although perforation is a rare complication of Peribulbar Anesthesia in normal eyes, the severity of complications in this study point to the importance of giving all patients, not only those with risk factors (eg, myopia, scar formation), detailed information about the possible risks and complications of Peribulbar injections compared with those of other methods such as topical Anesthesia and general Anesthesia.

  • topical versus Peribulbar Anesthesia in clear corneal cataract surgery
    Journal of Cataract and Refractive Surgery, 1996
    Co-Authors: Martin Zehetmayer, U Radax, Christian Skorpik, Rupert Menapace, M Schemper, Herbert Weghaupt, U Scholz
    Abstract:

    Abstract Purpose: To evaluate the efficacy of topical Anesthesia as an alternative to Peribulbar Anesthesia in clear corneal cataract surgery. Setting: Department of Ophthalmology, University of Vienna, Austria. Methods: In this prospective, double-blind clinical trial, 36 patients had bilateral cataract surgeries performed from 1 to 3 months apart. Half of the patients had topical Anesthesia for the first surgery and Peribulbar Anesthesia for the second surgery. The other half had Peribulbar first and then topical. All surgery was done using a temporal clear corneal approach and bimanual phacoemulsification followed by in-the-bag intraocular lens implantation. Subjective pain was assessed using a visual analog scale of no pain (0%) to worst pain imaginable (100%) and intraoperative motility using a rank scale of adverse motility (−5) to ideal patient cooperation (+5). Results: Subjective pain was comparable whether topical or Peribulbar Anesthesia was used (mean 10.75 versus 10.97%; P > .6). Patient cooperation (motility) was significantly better when topical Anesthesia was used (+2.16 versus +1.11; P = .03). There were no significant differences in complications. A Peribulbar block was given in addition to the topical Anesthesia in two cases. Conclusions: Topical Anesthesia is a safe, effective alternative to Peribulbar Anesthesia in clear corneal cataract surgery.
