Objective: To compare the prevalence of angle closure in eyes with retinal vein occlusion (RVO) with control eyes and assess the possible association between angle-closure and RVO.
Patients And Methods: This prospective, blinded case-control study included patients with a history of RVO (cases) and control individuals matched for age and refractive error. Clinical characteristics and angle-based structures derived from anterior-segment optical coherence tomography (AS-OCT) were analyzed.
Purpose: To investigate whether adding accelerated under-flap corneal cross-linking to hyperopic laser in situ keratomileusis (LASIK-ufCXL) affects postoperative stability and regression, visual and refractive outcomes, and subjective quality of vision.
Methods: This prospective comparative contralateral eye study included 51 patients with hyperopia (102 eyes) who received LASIK-ufCXL in the eye with highest defocus equivalent (DEQ) or randomized when DEQ equal, with the contralateral control eye receiving LASIK alone. After excimer ablation, 0.
Background: The short- and medium-term outcomes of iStent have been extensively studied; however, only few studies have investigated its long-term outcomes. Here, we assessed the long-term efficacy and safety of two iStents with concomitant cataract surgery in glaucomatous eyes while also evaluating measures of disease stability using visual field and optical coherence tomography (OCT) of the optic nerve and the macula throughout 8 years of follow-up.
Methods: This longitudinal, single-center consecutive case series included glaucomatous eyes that underwent implantation of two first-generation trabecular micro-bypass stents (iStent) with concomitant cataract surgery.
Background: To determine the prevalence of zonulopathy in a large cohort of eyes with primary angle closure disease (PACD) that underwent cataract surgery.
Methods: Retrospective consecutive case series of PACD eyes (including primary angle closure suspect, primary angle closure, and primary angle closure glaucoma) that underwent phacoemulsification cataract surgery or clear lens extraction between 2009 and 2020 at a single ophthalmology centre. Those with risk factors for zonulopathy such as history of trauma, pseudoexfoliation syndrome, intraocular surgery, retinitis pigmentosa or connective tissue disorders were excluded.
Objective: To assess the knowledge of corneal transplantation, willingness toward corneal donation, and the efficacy of a short informational and motivational video in increasing the willingness toward corneal donation among Canadian adults.
Methods: Cross-sectional interventional study. A survey targeted Canadian adults, assessing their knowledge and attitude toward corneal donation and the efficacy of a 1-minute-long informative and motivational video on increasing willingness toward corneal donation.
Precis: This longitudinal case series provides valuable long-term data on the safety and efficacy of iStent inject with concomitant cataract surgery. Patients experienced significant and durable reductions in both intraocular pressure (IOP) and medication burden through 3 years postoperative.
Purpose: The purpose of this study was to examine the 3-year effectiveness and safety of iStent inject second-generation trabecular micro-bypass stent implantation with concomitant phacoemulsification cataract surgery in eyes with various glaucoma subtypes and severities.
