Pemantauan tekanan intrakranial dibutuhkan sebagai upaya untuk menghindari kerusakan otak sekunder. Pemeriksaan baku emas pemantauan ini masih bersifat invasif dan meningkatkan risiko infeksi perdarahan. Oleh karena itu, diperlukan pemeriksaan non-invasif yang dapat menggambarkan secara kontinu. Salah satu tersebut adalah pengukuran diameter selubung nervus optikus berbasis ultrasonografi. tela...

Both peripheral displacement thresholds and measurement of optic disc parameters have been advocated in the early diagnosis of glaucoma at the stage before scotomata are detected on conventional visual field assessment. The peripheral movement displacement thresholds were measured in 50 eyes of 50 patients with ocular hypertension and a significant correlation was found with neuroretinal rim ar...

Accurately detection of retinal landmarks, like optic disc, is an important step in the computer aided diagnosis frameworks. This paper presents an efficient method for automatic detection of the optic disc’s center and estimating its boundary. The center and initial diameter of optic disc are estimated by employing an ANN classifier. The ANN classifier employs visual features of vessels and th...

PURPOSE Reduced birth weight is associated with an increased risk of visual impairments. This study was undertaken to determine whether prenatal exposure to a chronic compromise sufficient to cause fetal growth restriction (FGR) results in long-term alterations to the retina and optic nerve. METHODS FGR was induced by umbilicoplacental embolization (UPE) in two cohorts of pregnant ewes from (...

BACKGROUND AND OBJECTIVE To investigate the relationship between optic nerve sheath diameter, optic nerve diameter, visual acuity and osteopontin, and neurofilament heavy chain in patients with acute optic neuritis. PATIENTS AND METHODS Sonographic and visual acuity assessment and biomarker measurements were executed in 23 patients with unilateral optic neuritis and in 19 sex- and age-matched...

Interscalene brachial plexus (ISB) block is widely used in shoulder and humerus surgeries, especially patients that have high risk for general anesthesia. Increased intracranial pressure (ICP) not among the complications of this because there no data about issue literature. In traumatic case report, a patient with headache known meningioma his right temporo occipital region gonna proximal fract...

Glaucoma represents a group of neurodegenerative diseases characterized by structural damage to the optic nerve and the slow, progressive death of retinal ganglion cells (RGCs). Elevated intraocular pressure (IOP) is traditionally considered to be the most important risk factor for glaucoma, and treatment options for the disease have hitherto been limited to its reduction. However, visual field...
