Abstract Details

Purpose:

To report a rare case of 61 years old patient with Neurofibromatosis type 1(NF 1) who presented with recent onset vision loss due to optic nerve glioma.

Setting:

Aravind Eye Hospital, Pondicherry

Methods:

Cross-sectional study

Results:

A 61 years old female presented with headache and defective vision in left eye over past 4 months. There were multiple neurofibromas involving her face, limbs, chest, abdomen and trunk. Systemic examination was normal. Ocular examination revealed visual acuity of 6/6 in right eye and 6/36 in left eye. Relative afferent pupillary defect, Lisch nodules, disc pallor, defective colour vision and depressed visual fields were noted in left eye. Right eye was normal except for Lisch nodules. Magnetic resonance imaging of brain showed left optic nerve glioma. Patient’s daughter and son also had similar nodular swellings.

Conclusions:

Optic nerve glioma is a paediatric tumour. Occurrence or progression in a sixty year old is extremely rare. Optic pathway glioma is a possible cause for visual decline in adult NF1 patients.
