877 October 2014 A PATIENT presented for enucleation of a blind, painful eye. After sedation, an appropriate orbital-rated 12–6 MHz L-25 ultrasound transducer (Sonosite, Bothell, WA) was positioned obliquely on the upper eyelid. The orbit and adnexa were identified, and a retrobulbar block was performed via an infero-temporal approach.1 The needle’s final position was confirmed on ultrasound. T...

BACKGROUND The purpose of this study was to evaluate the efficacy and safety of episcleral single-injection anesthesia in a large number of patients. METHODS Over a period of 5 yr, in four institutions, anesthesiologists involved in this prospective study completed a standardized form to evaluate single-injection medial canthus high-volume episcleral anesthesia. The success rate of the block ...

The neurologic and cardiac toxicities of local anesthetics lidocaine and bupivacaine have long been documented and can be potentiated by inadvertent systemic administration, pre-existing cardiac disease, shock states, and renal failure. We report a peculiar case of acute lidocaine and bupivacaine toxicity during orbital surgery in a woman with stable chronic systolic heart failure due to unexpe...

OBJECTIVE To evaluate the efficacy of supra-Tenon capsule placement of original Molteno vs Molteno 3 tube implants (Molteno Ophthalmic, Dunedin, New Zealand) in black patients with refractory glaucoma. METHODS A retrospective study comparing the efficacy of supra-Tenon capsule placement of the original Molteno tube implant (130-mm(2) plate size) with the newer Molteno 3 tube implant (175-mm(2...

PURPOSE Transdifferentiation of human Tenon fibroblasts to myofibroblasts and subsequent deposition of extracellular matrix is a key step in the scarring after glaucoma filtration surgery. The p38 signaling pathway plays an important role in cell proliferation and differentiation, and its upstream regulators and downstream molecules are widely distributed in the eye. We aimed to investigate the...

Bei mittelschwerem bis schwerem Glaukom ist die Trabekulektomie nach wie vor der «Goldstandard» für Senkung des Augen­innendrucks (IOP); allerdings erfordert diese Methode eine umfangreiche postoperative Behandlung. Die mikroinvasive Glaukomchirurgie (MIGS) wurde entwickelt, um den intra- und postoperativen Pflegeaufwand zu verringern gleichzeitig akzeptable Augeninnendrucks bei Patienten mit l...

For a long time, the geometry dimensions of tenons have been designed through empirical methods, which is not beneficial to designers and manufacturers results in more time spent construction greater amount waste wood materials. In this study, an optimal methodology combining finite element analysis (FEA) with response surface method (RSM) was proposed investigate effect tenon geometric (length...

Vitrektomi adalah operasi mata untuk mengangkat bagian vitreous body. Hingga saat ini berbagai teknik anestesi tengah dikembangkan mencapai kondisi ideal. Teknik kombinasi general anesthesia dengan blok subtenon pada vitrektomi memiliki potensi yang bagus mengurangi nyeri pascaoperasi, insiden refleks okulokardiak dan jumlah penggunaan analgesia. Pada laporan ini, dilaporkan pasien laki-laki be...
