Choroidal thickness was found to be significantly increased in migraine patients during the attack period when compared to basal levels. The possible implications of this finding on the association between migraine and glaucoma are discussed.

Physiological palpebral fissure asymmetry is a common observation in a physician's everyday practice. The goal of this study was to examine the relationship between palpebral fissure height (PFH) and ocular dominance. Sixty-nine healthy volunteers (42 female, 27 male) were included in this research, and ocular dominance was determined using hole-in-the-card and pointing-a-finger tests. Those volunteers with inconsistent test results were excluded. Standard photographs were taken of all of the subjects in the primary position with a consistent background and photographic equipment. The PFHs were measured using an ImageJ analyser, and a mixed ANOVA was used for the statistical analysis. Overall, 87% of the participants showed small differences in their PFHs, with their dominant eyes being significantly wider than their non-dominant eyes (10.51 ± 0.97 vs. 10.32 ± 1.03; p = .001). This study revealed that ocular dominance has a significant effect on the PFH. Further research is required to understand the importance of this association in daily practice.

Introduction: Headache after spinal anesthesia is a frequently seen complication. The mechanism of headache is intracranial hypotension due to cerebrospinal fluid leaking after meningeal traumatization. The headache is typically orthostatic. Cerebral venous thrombosis is a rare disease. The most common clinical symptom is headache. Headache can appear with different characteristic features.

Introduction: Many serious neurological and ophthalmological diseases are reported in patients presenting to the emergency service with the complaint of diplopia. Near reflex spasm is a rare cause of diplopia, which may mimic abducens nerve palsy. Case Report: A 27-year-old female presented to the emergency service with the complaint of diplopia and blurred vision. There was no drug usage or exposure to toxic substances. In the physical examination, convergent strabismus was observed and the pupils were miotic. Ciliary spasm was detected in the ophthalmologic examination. The results of the examinations for organic etiologies were negative. The patient recovered after the application of cycloplegic drops and the arrangement of treatment after psychiatric examinations. Conclusion: Considering near reflex spasm in patients presenting with diplopia could save the emergency services, where time is important, from unnecessary further examinations. It should not be forgotten to pay attention to miosis because it is the most important clue evocative of this rare disease.
