RESUMO
CASE REPORT: We report on a 37-year old patient with sudden onset of pain of the right scalp and an ipsilateral small pupil, presenting five weeks after chiropractic manipulation of the neck. METHODS/RESULTS: Pharmacologic pupil testing showed a postganglionic Horner's syndrome on the right side. Magnetic resonance angiography confirmed the diagnosis of a dissection of the right internal carotid artery at a subacute stage. CONCLUSION: There appears to be a causal relationship between carotid artery dissection and the chiropractic manipulation of the cervical spine. Ophthalmological signs played the key role in detecting this complication.

We investigated abnormalities of the retinal cone ON- and OFF-pathways in 24 males with Schubert-Bornschein congenital stationary night blindness (CSNB). Substantial differences were found between both CSNB types. In incomplete type, a-, b- and d-waves were reduced and delayed, whereas in complete type only the b-wave showed significant changes. Oscillatory potentials (OPs) were not discernible from noise in incomplete CSNB and showed significant peak alterations of the ON-OPs only in complete CSNB. In the complete CSNB type, the ON pathway appeared to be mainly affected. In the incomplete CSNB form marked involvement of both the ON and the OFF pathways was noted.
