Introduction: This study investigated the intraocular pressure (IOP) fluctuation as assessed by the water drinking test (WDT) in open-angle glaucoma (OAG) patients after combined cataract surgery with iStent implantation.

Methods: This was a prospective non-randomized comparative study. Eyes with OAG and cataracts that were planned for either combined phacoemulsification and iStent implantation (iStent+CS) or phacoemulsification alone (CS) were recruited.

Allergic conjunctivitis (AC) comprises a group of conditions triggered by environmental allergens, substantially diminishing the quality of life, particularly among children and adolescents. The mechanical impact of eye rubbing in patients with AC is known to induce biomechanical alterations in the cornea. Modern instruments enable the detection and quantification of these corneal biomechanical changes.

Purpose: To evaluate the real-world efficacy and safety of iStent implanted standalone or combined with phacoemulsification in open-angle glaucoma (OAG) patients.

Methods: This is a retrospective observational study of OAG patients who underwent standalone or combined iStent procedures were reviewed. Inclusion criteria included age over 18 years and open angle on gonioscopy.

Background and objective In corneal neovascularization, the peri-corneal vascular structure grows into a normally avascular cornea. This is due to an imbalance between the angiogenic and anti-angiogenic factors that sustain corneal transparency. There are various etiologies of this condition, and they can be divided into infective or non-infective causes, such as inflammation, trauma, or surgical causes.

This case report aims to describe a case of unilateral central retinal artery occlusion (CRAO) with cilioretinal artery sparing, which was complicated by neovascular glaucoma (NVG). A 75-year-old Indian woman with underlying normal tension glaucoma presented with the sudden onset of painless generalized blurring of the right eye's vision for a week. Her right eye vision was hand motion with the presence of a right relative afferent pupillary defect.

Iridodialysis occurs less commonly due to ocular surgeries as compared to trauma. Several approaches to iridodialysis repair have been described in the literature. In this report, we describe a novel technique to treat iridodialysis that occurred due to complicated extracapsular cataract extraction (ECCE).

Background: To evaluate the satisfaction of surgeons and trainees with three-dimensional (3D) ophthalmic surgery during a demonstration compared to traditional surgery.

Methods: This validated questionnaire-based study was conducted over 1-month during which Ngenuity 3D surgery was demonstrated. All surgeons and trainees exposed were recruited to complete a questionnaire comprising visualization, physical, ease of use, teaching and learning, and overall satisfaction.
