Survey on the management of orbital and intraocular tumors among oculofacial surgeons in the Asia-Pacific region

摘要

A web-based anonymous survey was performed to assess the common practices of oculofacial surgeons in the management of orbital and intraocular tumors in the Asia-Pacific region. The questionnaire comprised a series of questions covering controversial topics sent via email to 131 oculofacial surgeons across 14 countries in the Asia-Pacific region. A total response rate of 61.7% was achieved from May to December 2012. The most common benign orbital tumor was cavernous hemangioma (39.6%) and the most common malignant orbital tumor was lymphoma (85.7%). 40% of surgeons recommended orbital radiation, for which the most common indications were thyroid eye disease (70.0%) and malignancy (30.0%). The most common orbitotomy approach was lateral (79.2%). Most surgeons (87.1%) offered enucleation for retinoblastoma, but there was also a significant proportion that offered chemoreduction with transpupillary thermotherapy or cryotherapy (58.1%). Fewer surgeons offered brachytherapy (16.1%) and intra-arterial chemotherapy (6.5%). When performing enucleation for retinoblastoma, 81.8% of surgeons performed a primary orbital implant placement. The most preferred type of implant was silicone/acrylic (90.2, 90.2 and 87.8% for elderly, adults and children, respectively). The majority of surgeons used donor sclera (57.5%) or no wrapping material at all (32.5%). Almost all surgeons (95.1%) did not drill and peg the implant for motility. We report the results of the first survey of oculofacial surgeons in the Asia-Pacific region on the management of intraocular and orbital tumors. In comparison with previous surveys performed in the USA and the UK, we found the practice patterns of the Asia-Pacific surgeons to be comparable.
