Advances in glaucoma surgery: Paradigm shift in management

Clinical utility of anterior segment swept-source optical coherence tomography in glaucoma

Unlabelled: Optical coherence tomography (OCT), a noninvasive imaging modality that uses low-coherence light to obtain a high-resolution cross-section of biological structures, has evolved dramatically over the years. The Swept-source OCT (SS-OCT) makes use of a single detector with a rapidly tunable laser as a light s …

Eye drop administration in patients attending and not attending a glaucoma education center

Background: To assess the technique of glaucoma eye drop instillation in patients who have and have not attended glaucoma education sessions. To compare this with their subjective perception of eye drop use and identify factors associated with improved performance. Patients and methods: An observational study of 55 par …

Primary angle-closure glaucoma: A retrospective interventional case series in South India

Purpose: To report the outcome of surgically managed primary angle-closure glaucoma (PACG) cases in 84 eyes at a tertiary eye hospital in South India. Materials and methods: Retrospective analysis of medical records of 84 eyes of 81 patients with PACG, who were surgically managed over 4 years at tertiary eye hospital i …

Comparison of Goldmann applanation tonometer, Tono-Pen and noncontact tonometer in children

Background: To evaluate the agreement of Goldmann applanation tonometer (GAT) with Tono-Pen and noncontact tonometer (NCT) for measurement of intraocular pressure (IOP) in pediatric age group and to evaluate the correlation between central corneal thickness (CCT) and IOP measured with the tonometers used. Materials and …

Visual acuity and refractive status of Omani students with refractive error in grades 1, 4 and 7: A retrospective cohort study

Background: The visual and refractive status were assessed for grade 7 students in seven governorates in Oman. The health records were reviewed to assess the rationale for their previous school-based vision screening. Methods: A representative sample of 7(th) grade students with a refractive error (RE) was examined by …

Quantitative spectral domain optical coherence tomography thickness parameters in type II diabetes

Purpose: To elucidate the changes in retinal thickness and individual layer thickness in subjects with diabetic retinopathy (DR) using spectral domain optical coherence tomography (SDOCT). Materials and methods: A total of 251 eyes from 170 subjects were included in this study. The study sample was subdivided into nond …

Awareness, knowledge, and barriers to low vision services among eye care practitioners

Background: Eyesight plays an important role in our day today life. When the vision gets hampered, daily activities of an individual will be affected. The prevalence of visual impairment is increasing across the globe, with more burdens on the developing world. The uptake of low vision services remains to be low in dev …

The effect of intravitreal bevacizumab and ranibizumab on macular edema of the contralateral eye: A comparative study of two anti-VEGFs

Purpose: To compare the effects of bevacizumab and ranibizumab on the visual function and macular thickness in the contralateral (untreated) eye of patients with bilateral diabetic macular edema (DME). Materials and methods: Thirty-nine patients with bilateral DME, who had been treated with both bevacizumab and ranibiz …

Organophosphate retinopathy

Organophosphates have rarely been reported to cause various ocular sequelae including retinal degeneration. Retinal manifestations have been rarely reported and poorly characterized. We describe a case of a 76-year-old man with vision loss beginning in his 20s due to acute on chronic exposure to dimethoate, an organoph …
