Specimens were examined from 23 orbits of 18 Asians (9 orbits in males, 14 in females), aged 63 to 97 years at death. All specimens were fixed in 10% buffered formalin before use. The orbital contents were incised parallel to the optic nerve, after which the lengths of both short and long axes of the IOM were measured and the ratio of short to long axes was calculated. The mean lengths of each short or long axis of the IOM were 2.27 &plusmn; 0.49 mm and 7.23 &plusmn; 0.97 mm, respectively. The average ratio was 0.32 &plusmn; 0.07. There were no significant differences in laterality or gender. This study determined the normal IOM thickness in Asian cadavers, the outcome of which could be useful for detection of IOM involvement in Graves&rsquo; orbitopathy.Keywords: inferior oblique muscle, Asian, thickness, quasi-sagittal plane Yasuhiro TakahashiHirohiko KakizakiTakashi NakanoKen AsamotoMasayoshi IwakiDove Medical PressarticleOphthalmologyRE1-994ENClinical Ophthalmology, Vol 2008, Iss Issue 2, Pp 299-302 (2008)
