Article Abstract
Purpose: To measure anterior segment parameters of the eye in myopic Saudi population using Pentacam.
Method: This is retrospective cross-sectional study. Subjects were divided into three groups: low, moderate and high myopia groups. Anterior segment parameters including: central corneal thickness (CCT), thinnest corneal thickness (TCT), apex corneal thickness (Apex CT), corneal volume (CV), anterior chamber depth (ACD), anterior chamber volume (ACV) and corneal astigmatism (CA) were measured by Pentacam.
Results: A total of 504 eyes of 252 Saudi subjects with myopia were included in this study. The mean age ± standard deviation (SD) of subjects was 28.73 ± 6.18 years. The mean CCT, TCT, Apex CT, CV, ACD, ACV and CA for all myopic subjects were 557.21 ± 29.36, 554.09 ± 29.28, 556.10 ± 37.06, 61.30 ± 3.23 μm, 3.31 ± 0.27 mm, 211.15 ± 34.22 mm and 0.89 ± 0.52 D, respectively. No significant differences (P > 0.05) were found between right and left eyes in all anterior segment parameters of all myopic eyes. However, a significant difference (P < 0.05) was found in ACD between low (3.27 ± 0.26 mm) and moderate (3.35 ± 0.30 mm) myopic groups. Within low myopia group, significant differences (P < 0.05) were found in ACD, ACV and CA between different genders. Anterior chamber depth and ACV values were lower in females while CA was lower in males. In addition, significant positive correlation was found between ACV and ACD in all myopic groups.
Conclusion: This study provided valuable measurements of the anterior segments parameters of the eye in myopic Saudi population. These parameters could be useful for ophthalmic practitioners in the clinic.

Background: Portable sphero-cylinder refraction is useful for remote medical missions and self-checking. A novel, inexpensive, handheld optical scope with an internal vision chart and adjustable diopter lens, called the Moptim MRT-200, was therefore validated.
Methods: Young, capable patients from a pediatric eye practice had dry refraction estimates with the Moptim MRT-200, Adaptica 2WIN photoscreener, and Monocular Retinomax compared with actual refined retinoscopy.

Fungal cerebral aneurysms, particularly those resulting from direct invasion by fungal sinusitis, are rare and often fatal when involving the cavernous segment of the internal carotid artery (ICA). We present a case of a ruptured fungal ICA aneurysm caused by sinusitis, successfully treated with parent artery occlusion (PAO). In this case, an 80-year-old woman presented with right ptosis, facial pain, and cranial nerve III, IV, and VI palsies.

BACKGROUND Degenerative cervical spondylotic myelopathy (CSM) is an age-related degenerative condition of the vertebral bodies, discs, and ligaments that can cause pressure on the spinal cord and nerves. Anterior cervical corpectomy and fusion is a widely used surgical approach for treating CSM, aiming to decompress the spinal cord, restore vertebral alignment, and improve fusion rates, thus providing relief to affected patients. This study was a neurological and biomechanical evaluation of 72 patients with degenerative CSM at 3, 6, and 12 months following anterior cervical corpectomy and fusion.

Purpose: This study aimed to evaluate clinical and radiological outcomes of patients who underwent anterior cervical discectomy and fusion (ACDF) without additional anterior plate fixation.
Methods: A retrospective single-center analysis was conducted. Clinical outcomes were assessed by the Visual Analog Scale (VAS) scores, Neck Disability Index (NDI), and Odom's criteria.
