Examination for orbital tumours
The oculoplastic surgeon carries out a comprehensive ophthalmological examination, including a vision test, colour vision test, assessment of eye movement, pupils, visual fields etc. It may be necessary to instil drops that dilate the pupil to examine the retina and optic nerve.
If an orbital tumour is suspected, a CT scan and/or an MRI will be necessary.
Treatment for orbital tumours
A biopsy is taken for study. The biopsy is done under either local or general anaesthetic, through a small skin incision or an incision in the conjunctiva (close to the eye). If the tumour is easily accessible it may be possible to remove the entire tumour out at the time of the biopsy. Some tumours can be treated with chemotherapy or radiotherapy. These treatments are usually done by oncologists, with whom the oculoplastic surgeon will work closely.
Some tumours don’t need treatment, in which case simple follow-up appointments to check visual function every few months are all that is necessary. If surgical treatment is required, it will be carried out by an oculoplastic surgeon, sometimes in conjunction with other specialist such as plastic surgeons, neurosurgeons or maxillofacial surgeons.
