Efficacy comparison of intravitreal injections of conbercept and ranibizumab for severe proliferative diabetic retinopathy.
Abstract OBJECTIVE: To determine the efficacy of preoperative intravitreal injections of conbercept (IVC) and ranibizumab (IVR) on postoperative best-corrected visual acuity (BCVA), vitreous hemorrhage (VH), and neovascular glaucoma (NVG) in a population with proliferative diabetic retinopathy (PDR) undergoing vitrectomy. DESIGN: Retrospective, cross-sectional study. PARTICIPANTS: 386 patients with severe PDR (428 eyes). METHODS: The patients who did not receive IVC or IVR were assigned to group A (125 eyes), the patients who received IVR (0.5 mg) were assigned to group B (146 eyes), and the patient...

OCT angiography fractal analysis-based quantification of macular vascular density in branch retinal vein occlusion eyes.
This study is a retrospective observational comparative case series. Diagnosed cases of unilateral BRVO that underwent treatment and resolved were included. The other eye served as control. METHODS: OCTA images of the cases and control eyes were analyzed using fractal dimension on the MATLAB platform. Vascular density fraction was calculated for each eye for both the retinal vascular layers. Images were cleaned of artifacts before processing. Total vascular density in normals was compared with those with branch retinal vein occlusion. RESULTS: 116 eyes were normal and 98 had BRVO. The mean age of the normals was ...

Ethambutol-induced optic neuropathy in renal disorder: a clinico-electrophysiological study.
Abstract OBJECTIVE: To report the spectrum of ethambutol induced optic neuropathy in a group of renal patients with tuberculosis and the role of visual evoked response (VER) in evaluating this disorder. METHODS: Twenty-three renal patients who were started on ethambutol as a part of anti-tubercular treatment for tuberculosis in India, were divided into 4 groups based on glomerular filtration rate (GFR): group 1-chronic kidney disease (CKD) with GFR 30 ≤ 60 mL/min; and group 4-GFR> 60

Optimizing preoperative requirements for outpatient cataract surgery at the Royal Alexandra Hospital.
CONCLUSIONS: Based on the literature, best practice guidelines, and a cost analysis, it was decided that patients undergoing routine cataract surgery in Edmonton Zone Hospitals under regional anaesthesia would no longer require physician history and physicals and ECGs. Elimination of the preoperative requirements for all but select high-risk patients meant that 100% of patients who arrived for cataract surgery would not have outstanding presurgery requirements.

Charles Bonnet syndrome: development and validation of a screening and multidimensional descriptive questionnaire.
CONCLUSION: The questionnaire will be a valuable aid in screening for Charles Bonnet syndrome among the low vision clientele. However, the screening will need to be supplemented by a focused low vision interdisciplinary assessment including a visual examination and a clinical interview with a psychologist.

Rehabilitation with biofeedback training in age-related macular degeneration for improving distance vision.
This article attempts to clarify the optimal methodology for BT and the types of patients who can benefit most from BT. METHODS: This is a retrospective review of cases who received BT with the macular integrity assessment (MAIA) microperimetre. Outcome measures selected for analysis were visual acuity, PRL location, fixation stability, fixation pattern orientation, reading acuity, critical print size, and reading speed. RESULTS: Out of 30 cases who received BT, only those with age-related macular degeneration and visual acuity of logMAR 0.8 (20/126) or poorer showed a visual acuity gain (statistically significan...

Reproducibility of minimum rim width and retinal nerve fibre layer thickness using the Anatomic Positioning System in glaucoma patients.
CONCLUSIONS: The minimum rim width and retinal nerve fibre layer thickness measurements using the Anatomic Positioning System protocol had overall excellent reproducibility and diagnostic performance.

Comparison of 2-year-results of mitomycin C-augmented trabeculectomy with or without cataract extraction in glaucoma patients.
CONCLUSIONS: Phacotrabeculectomy is comparably as effective as trabeculectomy alone in reducing IOP and the need for antiglaucomatous medication over a time interval of 2 years. We found indications that this favourable therapeutic effect is also true for patients needing phacoretrabeculectomy treatment.

Intimate partner violence as a mechanism of traumatic ocular injury in women.
CONCLUSION: IPV is an important mechanism of traumatic ocular injury. IPV-associated injuries tend to be severe in nature, as demonstrated by the high rate of globe laceration or rupture and subsequent enucleation in the study population. By appropriate screening and referral, ophthalmologists have an opportunity to redirect a potentially devastating course.

Urban diabetic retinopathy teleophthalmology screening: results and impact at the service corridor.
CONCLUSION: The FFCEs generated at the hospital service corridor by an urban community DR screening teleophthalmology project did not impact negatively on its services; moreover, the service corridor was exempted from providing FFCEs to 87.4% of the diabetic population it serves. This study may help provide cost-efficiency indications for a screening protocol that would include OCT availability at the imaging site and measure its positive effects. While DR of which DME was the main cause of referral for FFCE, incidental significant sight-threatening findings were significant and approached DR as a cause of referral; this s...

False corneal ectasia in patients referred for corneal crosslinking, topography-guided photorefractive keratectomy, and intrastromal corneal rings.
CONCLUSION: Analysis of data detected a misdiagnosis of ectasia in 20 patients (26 eyes), a finding of 2.0% (20 of 1000) of referred cases that did not satisfy the diagnostic criteria of corneal ectasia. These conditions are considered a contraindication to corneal crosslinking and there is usually no benefit to topography-guided PRK or intrastromal corneal rings. It is important that clinicians recognize the clinical findings of these conditions and differentiate from true keratoconus, pellucid marginal degeneration, or ectasia after laser vision correction.

Determining optimal ultrasound percent on time with long-pulse torsional phacoemulsification.
CONCLUSION: Increasing on-time percent does not improve efficiency under torsional long-pulse US. There is no significant change in chatter with increasing on-time percent. Increasing power increases efficiency despite chatter increase. Long-pulse US does not appear to influence torsional action in a clinically meaningful way.

Preoperative fasting for ambulatory cataract surgery: asystematic review.
Abstract Given the lack of policy standardization in Canada, this systematic review investigates the optimal duration of preoperative fasting in cataract surgery. A literature search was conducted on Ovid MEDLINE, with potential articles screened by 2 independent authors. The primary endpoint was the incidence of aspiration. Overall, 231 articles were screened, of which 6 were eligible. Two studies found no cases of aspiration in over 35 000 patients who underwent cataract surgery without preoperative fasting, some with intravenous sedation (50% in 1 series, less than 1% in the second). A survey of the British Oph...

Use of mobile health (mHealth) technologies in ophthalmology patients in Alberta.
CONCLUSION: Overall, the majority of ophthalmology patients do not search the internet for information on eye conditions. However, when stratified into separate age groups (less than and greater than age 60 years), the majority of younger patients search the internet for information on their eye condition(s), whereas the majority of older patients do not. As a result, one can conclude that age is a significant predictive factor in the use of internet technologies for information regarding eye conditions.
