Risk factors for epiretinal membrane formation and peeling following pars plana vitrectomy for primary rhegmatogenous retinal detachment, an OCT guided analysis.

Background: To evaluate the rate and risk factors of epiretinal membrane (ERM) formation and need for ERM peeling after pars plana vitrectomy (PPV) for uncomplicated primary rhegmatogenous retinal detachment (RRD).

Methods: Retrospective, single-center, cohort study of 119 consecutive patients (119 eyes) that underwent RRD repair using PPV. The primary outcomes were ERM formation, classified using an optical coherence tomography grading system, and the rate of ERM peeling.

Long-Term Visual Outcomes for a Treat-and-Extend Antivascular Endothelial Growth Factor Regimen in Eyes with Neovascular Age-Related Macular Degeneration: Up to Seven-Year Follow-Up.

Purpose: To report long-term visual and anatomical outcomes in eyes with neovascular age-related macular degeneration (nAMD) treated with a treat-and-extend regimen (TER) of intravitreal antivascular endothelial growth factor (anti-VEGF) injections in real-world settings.

Methods: Retrospective cohort study of consecutive patients with nAMD treated with a TER of anti-VEGF intravitreal injections by a single retina specialist (GC). Patients with nAMD who had at least one year of follow-up were identified using an electronic database.

Displacement of Retained Subretinal Perfluorocarbon Liquid Through Therapeutic Retinal Detachment Induced by Balanced Salt Solution Injection.

Purpose: To report a case of displacement of retained subretinal perfluorocarbon liquid (PFCL) through therapeutic retinal detachment (RD) induced by balanced salt solution (BSS) injection.

Methods: This is a surgical case report. We present a case of a 61-year-old woman who presented with subretinal PFCL at the papillo-macular bundle with best-corrected visual acuity (BCVA) of 20/200 at four weeks following RD surgery in her right eye.

Primary rhegmatogenous retinal detachment with inferior retinal breaks postoperative prone positioning results: 1 day versus 7 days.

Background: To compare the primary anatomical outcome of pars plana vitrectomy, 360° peripheral endolaser, and 15% octafluoropropane CF gas tamponade in patients with uncomplicated rhegmatogenous detachment and inferior retinal breaks, after 24-h postoperative prone positioning to similar patients with 1 week postoperative prone positioning.

Methods: Records of 5500 patients who underwent pars plana vitrectomy between 2008 and 2015 were retrieved. Collected data included age, gender, number of retinal quadrants with retinal breaks, number of retinal breaks, macula status on presentation (attached or detached), phakic status (phakic, pseudophakic, or aphakic), and primary anatomical outcome (at 1 and 3 months post-operative).

Factors associated with outcomes of pneumatic retinopexy for rhegmatogenous retinal detachments: a retrospective review of 422 cases.

Background: To determine the factors associated with anatomical and visual outcomes, and complications when using pneumatic retinopexy in the management of rhegmatogenous retinal detachments.

Methods: On a whole, 406 patients having undergone 422 primary pneumatic retinopexies for the management of rhegmatogenous retinal detachment at a tertiary care hospital, between January 2004 and December 2009, with a minimum follow-up of 3 months were included in this case series. Multivariate logistic regression was used to estimate associations of demographic and clinical factors with anatomical and visual outcomes.

Assessment of retinal and choroidal blood flow changes using laser Doppler flowmetry in rats.

Purpose: A new noninvasive laser Doppler flowmetry (LDF) probe (one emitting fiber surrounded by a ring of eight collecting fibers, 1-mm interaxis distance) was tested for its sensitivity to assess the retinal/choroidal blood flow variations in response to hypercapnia, hyperoxia, diverse vasoactive agents and following retinal arteries photocoagulation in the rat.

Materials And Methods: After pupil dilation, a LDF probe was placed in contact to the cornea of anesthetized rats in the optic axis. Hypercapnia and hyperoxia were induced by inhalation of CO(2) (8% in medical air) and O(2) (100%) while pharmacological agents were injected intravitreously.

Fibrin sealant in the treatment of retinal detachment in morning glory syndrome.

Purpose: To report the usage of fibrin sealant in the treatment of retinal detachment in morning glory syndrome.

Methods: A case report of an 8-year-old boy with a recent, macula-off, inferior, bullous retinal detachment associated to his morning glory syndrome that was first treated by a pneumatic retinopexy. The following day, his examination revealed a total retinal detachment and subretinal gas.

The effect of intravitreal injection of bevacizumab on retinal circulation in patients with neovascular macular degeneration.

Purpose: Intravitreal (ITV) injection of anti-VEGFs like bevacizumab are widely used to treat neovascular AMD. However, VEGF is essential for biologic functions such as blood pressure regulation. Indeed, anti-VEGF intravenous administration is associated with hypertension.

Possible venous air embolism during open eye surgery in a child.

Purpose: Although venous air embolism is a well recognized complication within most surgical subspecialties, it has only been reported recently during eye surgery in one adult, and never before in a child. We describe the case of a 17-month-old boy who sustained a possible air embolism during repair of an open trauma of his right eye.

Clinical Features: A vitrectomy through the pars plana with air-fluid exchange of the posterior chamber was performed under general anesthesia to remove a foreign body which had impaled the optic nerve.

Chronic angle-closure glaucoma secondary to a suprachoroidal effusion induced by central retinal vein occlusion.

A 68-year-old woman presented to the ophthalmology emergency clinic with a painful left eye of a few hours' duration. One month prior, the patient had presented with a central retinal vein occlusion in the same eye. Examination revealed an intraocular pressure of 32 mm Hg in the left eye with 360 degree angle closure unaltered by indentation, a patent iridectomy from a previous combined phacoemulsification and trabeculectomy surgery, and no evident iris or angle neovascularization.
