Purpose. To evaluate the relationship between internal carotid artery (ICA) stenosis and subfoveal choroidal thickness (SFCT) in the elderly population. Methods. A total of 42 eyes of 21 patients with more than 70% ICA stenosis (Group 1) on one side and less than 70% stenosis (Group 2) on the other side were recruited for this study. ICA stenosis was diagnosed using both the B-mode and Doppler ultrasound. The two groups were compared in terms of the percentage of stenosis, SFCT measurements, intraocular pressure, ocular perfusion pressure, refractive error, and peak systolic velocity. Eyes were examined with the RTVue-100 OCT device by the EDI-OCT technique. Results. The mean age of the patients was 71.9 ± 10.8 years. The mean percentage of ICA stenosis was 74 ± 4.9% in Group 1 and 47.5 ± 7.7% in Group 2. The mean SFCT was 231.9 ± 44.6 μm in Group 1 and 216.2 ± 46.8 μm in Group 2, which was significantly lower (P = 0.028). A statistically significant positive correlation was found between the percentage of internal carotid artery stenosis and SFCT (r = 0896, P = 0.001). Conclusions. Compensatory SFCT increase can be seen in ipsilateral internal carotid artery stenosis greater than 70%.

In this study, we aimed to determine the characteristics of the cVEMP and ABR responses of patients with VM and migraine in contrast to healthy controls. In this study, cVEMP and ABR changes during the VM attack period were compared with the cVEMP and OBJECTIVE: Vestibular migraine (VM) is a clinical condition characterized by temporal overlap between vestibular symptoms and migraine. In this study, we aimed to determine the changes in vestibular myogenic potential (cVEMP) and auditory brainstem response (ABR) in patients with VM and migraine. MATERIALS and METHODS:A total of 86 participants with no hearing loss or additional disease between the ages of 18 and 45 were enrolled in three different groups: group 1, VM; group 2, migraine without aura; and group 3, healthy controls. cVEMP and ABR were performed for all participants during attacks and attack-free periods. The differences between the right and left sides were calculated. RESULTS:There was no significant difference in cVEMP p13-n23 latencies between any of the groups. There were statistically significant differences related to cVEMP p13-n23 amplitudes between groups 1, 2, and 3. This significant difference originated from group 1 when compared with the other groups (p<0.05). When we compared the cVEMP results of patients with VM during attack and attack-free periods, a statistically significant decrease was determined in the p13-n23 amplitude values during the attack period (p<0.01). Additionally, when we compared group 1 and group 3, the wave V peak latencies in ABR were significantly prolonged in group 1 (p<0.05).CONCLUSION: cVEMP and ABR can be used as diagnostic criteria for patients with VM during attacks. Further studies with larger groups are needed to verify our findings.

The rare syndrome of perioral myoclonia with absences (POMA) is described as a specific type of idiopathic generalized epilepsy in which absence seizures are accompanied by prominent perioral myoclonus as a consistent symptom. We present a 52‐year‐old man who was referred to our department due to treatment‐resistant epilepsy. Typical seizures were described as rhythmic twitching of the lips which started at six years old, and his first convulsive seizure occurred at around 20 years old. Based on video‐EEG recordings, we present two distinct EEG patterns accompanied by slight differences in clinical manifestations, which appear to be atypical of POMA. Firstly, consciousness was preserved during seizures, with no manifestation of absences. Secondly, regarding the EEG features, in some of the seizures, the perioral motor symptoms were tonic rather than myoclonic. The defining features of POMA are discussed in relation to this case.
