Nyeri kepala merupakan penanda adanya gangguan intrakranial. Nervus optikus merupakan saraf kranialis yang mudah dipengaruhi langsung adanya gangguan intrakranial. Kalimatnya Jumping. Kelainan nervus optikus dapat diketahui dengan adanya pelebaran optic nerve sheath diameter (ONSD). ONSD dapat diukur dengan transorbital sonografi yang bersifat nonimvasif. Penelitian ini bertujuan membedakan diameter ONSD pada orang yang nyeri kepala dan orang normal. Penelitian ini menggunakan pendekatan observasional analitik dengan metode cross sectional. Responden diambil dari pasien rawat inap dan responden normal. Hasil penelitian didapatkan rata – rata nilai ONSD pada pasien nyeri kepala adalah 0,52 ± 0,86 dan pada responden normal adalah 0,40 ± 0,57 (p < 0,05). Terdapat perbedaan signifikan nilai ONSD pada pasien normal dan nyeri kepala. Penelitian ini membuktikan bahwa terdapat gangguan intrakranial pada orang dengan nyeri kepala dan dapat digunakan sebagai deteksi dini.Kata Kunci: Optic Nerve Sheath Diameter (ONSD), Responden Normal, Nyeri KepalaHeadache is a sign of intracranial disorders. The optic nerve is a cranial nerve that is easily affected directly by intracranial disorders. The sentence is Jumping. Optic nerve abnormalities can be identified by the widening of the optic nerve sheath diameter (ONSD). ONSD can be measured by transorbital sonography which is nonimvasive. This study aims to distinguish the ONSD diameter in people with headaches and normal people. This research uses an analytic observational approach with cross sectional method. Respondents were taken from inpatients and normal respondents. The results showed that the average value of ONSD in headache patients was 0.52 ± 0.86 and in normal respondents was 0.40 ± 0.57 (p <0.05). There is a significant difference in the value of ONSD in normal patients and headaches. This research proves that there are intracranial disorders in people with headaches and can be used as early detection.Keyword: Optic nerve sheath diameter , headache , normal volunteer

Development of oligodendrocytes in rat corpus callosum was described as a sequential change in cytoplasmic density which progressed from light to medium to dark (1). In rat optic nerve, changes in cytoplasmic density were not observed, but significant changes in morphology occurred just prior to and during myelination (2). In our study, the ultrastructural development of oligodendrocytes was studied in newborn, 5-, 10-, 15-, 20-day and adult frontal cortex of the golden hamster (Mesocricetus auratus).Young and adult hamster brains were perfused with paraformaldehyde-glutaraldehyde in sodium cacodylate buffer at pH 7.3 according to the method of Peters (3). Tissue samples of layer V of the frontal cortex were post-fixed in 2% osmium tetroxide, dehydrated in acetone and embedded in Epon-Araldite resin.
