Composed of Schwann cells, these masses are generally slow growing and can be found in the peripheral nerve tract, often around the head and neck.
Finally, these multipurpose cells are key in the formation of protective outer barrier, or the perineurial sheath, that creates a vital separation for peripheral nerves.
Although science has yet to offer up conclusive evidence that Schwann cell transplantation is an effective treatment for demylelinating disorders, it is possible that this could be applied in clinical practice in the future.
While it may be difficult if not impossible to make the distinction on the basis of routine examination and diagnostic measures, it is key to be aware of the possibility of intraocular schwannomas and look for any atypical features that may present themselves.
[1] Intraocular schwannomas are treatable and there are several treatment options that may be considered, depending on the size and specific location of the tumor.
However, it is important to note that in the study conducted by You et al. all of the patients whose tumors were initially observed needed further treatment and enucleation as their conditions declined.
For tumors that are initially more aggressive, larger in size or suspected as cancerous, local resection and enucleation are also options.
Although follow-up data has shown the potential need for re-excision and side-effects, these issues are minor and the general outcome for patients is excellent.
