Background:
Leiomyoma of the iris is a rare, benign
intraocular smooth muscle tumor. The tumor often originates from the sphincter
or less commonly from the dilator muscles. Recent studies have found that
leiomyomas occur much less frequently than previously reported. It is believed
strongly that iris leiomyoma has been previously overdiagnosed. Stricter
diagnostic criteria involving electron microscopy and immunohistopathology have
been added as new standards for reporting.
Pathophysiology:
Uncertainty to the
pathogenesis of iris leiomyoma exists. It is speculated that hormones play a
role in the pathogenesis due to the tumor's similarity to uterine leiomyoma
(fibroids) and its predilection to females. Structures in the iris of
neuroectodermal origin believed to give rise to the tumor include the sphincter
muscle and the dilator muscle. Structures in the iris of mesodermal origin
believed to give rise to the tumor include mesenchymal tissue.
Frequency:
-
In the US:
Incidence of smooth muscle tumors have been
reported as 2.3%, 4%, 9%, and 14.5% in different published series of iris
tumors.
Mortality/Morbidity:
No reported data on mortality and
morbidity from iris leiomyoma exist.
Race: This condition is reported only in white subjects.
Sex: Females are affected more frequently than males.
Age: Cases have been seen at ages 10-77 years.
