orbital malignancy. 2,8 However, when considering all subtypes of lympho-
mas, this general category makes up 28% of all the orbital lesions within
this age group, making this the most common orbital lesion, which is con-
sistent with other studies. 6 According to Demetri et al, 63% of all orbital
tumors in the senior adult population are malignant; primary, locally inva-
sive, or metastatic. Thus, orbital lesions in the adult population need urgent
work up and proper referral.

Presenting a large regional investigation of orbital mass incidence in
the state of Arkansas has limitations. Firstly, this study is a chart-based ret-
rospective review with retroactively applied review of prior patient informa-
tion. Additionally, initial screening of patients was by CPT code, which could
have excluded improperly labeled patients and pathology. Inclusion of only
histopathologically proven orbital masses likely skews the data presented
here towards lesions that were more likely (whether by size or symptoms)
to be surgically resected. Finally, this study is limited by its regional nature
and may not represent incidence in other areas of the U. S. and worldwide.
In summary, this study was undertaken to determine the number and
percentage of various lesions seen at tertiary centers in central Arkansas.
