PERBEDAAN OPTIC NERVE SHEATH DIAMETER (ONSD) PADA RESPONDEN NORMAL DAN NYERI KEPALA

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

B-Mode Transorbital Ultrasonography for the Diagnosis of Idiopathic Intracranial Hypertension: A Systematic Review and Meta-Analysis

In patients with idiopathic intracranial hypertension (IIH), transorbital sonography (TOS) may reveal an enlargement of the optic nerve sheath diameter (ONSD) and the presence of optic disc elevation (ODE), as a sign of an increase in intracranial pressure (ICP). We systematically reviewed the TOS findings in adults with IIH. MEDLINE, EMBASE, Cochrane Library and CENTRAL (1966 – May 2017) were searched to identify studies reporting data on patients with IIH assessed by B mode-TOS. Data were extracted and included in a meta-analysis, and the quality of the included studies was evaluated. 5 studies with 96 patients were included. The values of ODE were 0.8 – 1.2 mm and ONSD was 6.2 – 6.76 mm in IIH patients vs. 4.3 – 5.7 mm in controls. In IIH patients the ONSD was significantly higher compared to controls (overall weighted mean difference of 1.3 mm (95 % CI: 0.6 – 1.9 mm)). The meta-analysis of proportion of papilledema based on results of three studies revealed a pooled estimator of 87 % (95 % CI: 76 – 94 %). IIH patients have higher ONSD values and higher frequency of ODE compared to controls. The indirect, noninvasive ICP assessment using TOS may be useful in supporting the clinical diagnosis of IIH in adults by detecting increased ONSD values and the presence of ODE.
