BACKGROUND AND AIMS Visual evoked potentials (VEPs) assess the integrity of the visual pathways from the optic nerve to the occipital cortex. Optic disc cupping and visual field loss have been associated with prolongation of latency of VEP in primary open angle glaucoma (POAG). METHODS Pattern reversal and flash VEP tests were done in consenting 20 primary open angle glaucoma eyes and 40 norm...

G laucoma is a disease characterised by apoptotic ganglion cell death related, at least in part, to intraocular pressure. Any examination for glaucoma must therefore include some comment upon the health of these cells. Unfortunately, it is difficult to examine the ganglion cell layer ophthalmoscopically and so ophthalmologists typically rely on an analysis of a more visible ocular structure—the...

CASEREPORT A 43-year-old male attended the ophthalmology department with a 2-week history of painless reduction in vision in his left eye. Past ophthalmic history included bilateral allergic conjunctivitis, primary open angle glaucoma (POAG) right eye, and ocular hypertension left eye, diagnosed on his first visit 18 months ago. Systemic enquiry revealed a history of asthma, hypertension, obesi...

Objectives: To assess optic nerve changes in patients receiving anti-tuberculosis drugs and to at different time intervals of therapy. Study design settings: Descriptive cross-sectional study was conducted from August 2021 November Madinah Teaching Hospital, Faisalabad. Methodology: 200 eyes 100 therapy since 2-month, 4-month, 6 month 8 months were taken. Patients did not have any systemic dise...

localizing the optic disc (od) in retinal fundus images is of critical importance, since it is very similar to hard exudates (found in pathology) in color and brightness. because of the importance of od localization in clinical applications, many techniques have been developed. in this paper, we present the results obtained from two methods, correlation and least square, to approximate the opti...

We read with great interest the paper by McCoy et al. validating the neurological hemifield test (NHT) to detect and classify visual field loss caused by chiasmal or postchiasmal lesions. In this paper, more than 60% of glaucoma eyes misclassified as neurological according to the NHT score criterion had binasal defects. Therefore, interpreting binasal hemianopia is a particular challenge. To em...

PURPOSE To investigate the influence of various risk factors on thinning of the lamina cribrosa (LC), as measured with swept-source optical coherence tomography (SS-OCT; Topcon). METHODS This retrospective study comprised 150 eyes of 150 patients: 22 normal subjects, 28 preperimetric glaucoma (PPG) patients, and 100 open-angle glaucoma patients. Average LC thickness was determined in a 3 x 3 ...

BACKGROUND Since 1950, traditional Chinese medicine (TCM) cupping therapy has been applied as a formal modality in hospitals throughout China and elsewhere in the world. Based on a previous systematic literature review of clinical studies on cupping therapy, this study presents a thorough review of randomized controlled trials (RCTs) to evaluate the therapeutic effect of cupping therapy. METH...

Slit-lamp examination and stereoscopic fundus photography were found to be helpful in differentiating between physiological and glaucomatous cupping of the disc. Vertical ovalness of any cup in the disc should raise the suspicion of glaucoma, and the magnitude of the vertical cup: disc ratio is of particular significance.
