[The ophthalmologic signs in cerebellum tumor. Preliminary report].

INTRODUCTION

The aim of the study was an analysis of ophthalmic symptoms coexisting with the tumour of the cerebellum.

MATERIAL AND

METHODS

The study included 14 patients in the age between 21–55 years old with the tumor of cerebellum, who were operated in the Neurosurgery Clinic of the Pomeranian Medical University in Szczecin. The comprehensive ophthalmic examination were performed before and after 5 days from surgery. The examinations included evaluation of: pupillary reactions, visual acuity, fundus ophthalmoscopy, intraocular pressures, eye motility, visual field, optometrical tests and visual manual localization test.

RESULTS

The symptoms found before surgery of cerebellum tumors: diplopia (3 persons), early papilloedema (4 persons), nystagmus (2 persons), lack (5 persons) and weakened of convergence re􀏐lex (3 persons), latent strabismus (5 persons), manifest strabismus (3 persons). On the 5th day after the surgery were found: nystagmus (1 person), lack (5 persons) and weakened of the convergence re􀏐lex (3 persons). Visual manual localization was disparate depending on location of the tumor in the cerebellum; prevailed crossed and uncrossed localizations.

CONCLUSIONS

1. The natural dynamic of the tumor and surgical damage to the posterior cranial cavity structures can be monitored by assessment of the condition of the organ sight. 2. It is recommended to make the visual manual localization tests such as exponent disorders of senso-motorical deviations, which may occur in the patients with the cerebellum tumor.
