Vestibular schwannoma (VS), a benign neoplasm of the eighth cranial nerve, can disrupt both peripheral vestibular function and central oculomotor pathways. The caloric test evaluates the vestibulo-ocular reflex (VOR) pathway, while oculomotor testing assesses central neural mechanisms....

Discussion
Signed responses from readers of the wire.
Audiologists and vestibular specialists performing oculomotor and caloric testing on unilateral vestibular schwannoma patients can use this retrospective dataset as a reference for expected abnormality patterns, though the retrospective design limits definitive practice change.
Establishing a systematic profile of oculomotor and caloric findings in vestibular schwannoma may sharpen differential diagnosis and guide appropriate referral pathways for patients with unexplained unilateral vestibular dysfunction.
- 01Retrospective study of 122 patients with confirmed unilateral vestibular schwannoma.
- 02Both oculomotor (eye-movement) and caloric (warm/cool water ear irrigation) tests were assessed.
- 03Findings profile both peripheral vestibular and central oculomotor dysfunction in these patients.
- 04Published in Cureus; retrospective design limits causal inference.
- 05Sample size of 122 is relatively large for this specific tumour population.
Unilateral vestibular schwannoma produces identifiable abnormalities on both oculomotor and caloric testing reflecting peripheral and central vestibular dysfunction.
