Despite easing restrictions on social distancing and travel since the beginning of coronavirus disease 2019 pandemic, virtual interviews remain a widely used format for ophthalmology fellowship interviews. This study aims to evaluate the relative benefits and drawbacks of in-person versus virtual interviews during a cycle where both formats were prevalent. A prospective cross-sectional study surveyed all fellowship applicants ( = 311) who applied to Wills Eye Hospital and Bascom Palmer Eye Institute during the 2022 to 2023 application cycle.
View Article and Find Full Text PDFPurpose: To report the outcomes of pars plana vitrectomy for vitreous hemorrhage (VH) associated with retinal vein occlusion and to identify prognostic indicators.
Methods: Interventional, retrospective consecutive case series between 2015 and 2021.
Results: The study included 138 eyes of 138 patients (64 female and 74 male); 81 patients had branch retinal vein occlusion and 57 had central retinal vein occlusion.
Purpose: To describe the prevalence, management, and outcomes of rhegmatogenous retinal detachment (RRD) after incisional glaucoma filtering surgery.
Methods: All patients with a history of trabeculectomy or glaucoma drainage device surgery who were subsequently diagnosed with an RRD from January 1, 2016, to January 1, 2021, at the Wills Eye Hospital were identified.
Results: Forty-six eyes met the inclusion criteria.
Purpose: To evaluate the effect of loss to follow-up (LTFU) on outcomes in eyes with diabetic macular edema (DME) treated with anti-vascular endothelial growth factor (VEGF).
Design: Retrospective cohort study.
Methods: Single-center study of 90 eyes of 73 patients with nonproliferative diabetic retinopathy (NPDR) and DME treated with anti-VEGF injections who were LTFU for >6 months.
Background/aims: To evaluate the outcomes of eyes with macular oedema due to retinal vein occlusion (RVO) that are lost to follow-up (LTFU) after antivascular endothelial growth factor (VEGF) injections.
Method: A retrospective, single-centre, consecutive case series of RVO patients receiving injections who were LTFU >6 months was conducted. Data were collected from the visit before LTFU; return visit; 3 months, 6 months and 12 months after return; and the final visit.
Purpose: To evaluate the effect of physician face mask use on rates and outcomes of postinjection endophthalmitis.
Design: Retrospective, comparative cohort study.
Methods: Setting: Single-center.
Article Synopsis
- The study investigates the clinical features and visual outcomes of eyelet fractures in scleral-sutured enVista MX60 intraocular lenses (IOLs), focusing on patients who experienced displacement either during or after surgery.
- Among 25 identified cases, 20 fractures occurred postoperatively, leading to various complications; most commonly, Gore-Tex sutures were used to repair these fractures.
- Visual acuity significantly improved after lens replacement, going from a poor average of 20/317 to a much better 20/63, suggesting that despite the complications, surgical interventions can lead to positive visual outcomes.
Purpose: To assess perceptions of occupational risk and changes to clinical practice of ophthalmology trainees in the United States during the coronavirus disease 2019 (COVID-19) pandemic.
Design: An anonymous, nonvalidated, cross-sectional survey was conducted online. Data were collected from April 7 through 16, 2020.
Purpose: To determine the incidence and timing of delayed retinal breaks and retinal detachments (RDs) after acute posterior vitreous detachment (PVD) and associated risk factors.
Design: Retrospective case-control study.
Participants: Acute PVD eyes treated between October 2015 and August 2018 at a single academic retina practice.
Purpose: To examine rates of acute infectious endophthalmitis after pars plana vitrectomy (PPV) in eyes that received intraoperative subconjunctival antibiotics versus eyes that did not.
Methods: A retrospective, nonrandomized, comparative case series of 18,886 consecutive cases of transconjunctival 23-, 25-, and 27-gauge PPV over a 5-year period was performed. The impact of prophylactic intraoperative subconjunctival antibiotics on the development of acute infectious postoperative endophthalmitis was examined.
Purpose: To report longer-term outcomes of 27-gauge pars plana vitrectomy (PPV) in eyes with posterior segment disease.
Design: Multicenter, retrospective, interventional case series.
Participants: A total of 390 eyes of 360 patients undergoing 27-gauge PPV for a vitreoretinal surgery indication.
Purpose: To describe the utility of microperimetry testing in the diagnosis of a bilateral occipital stroke.
Methods: Retrospective case report.
Results: A 57-year-old male with hypertension presented with complaints of bilateral blurred central vision and bilateral hypertensive retinopathy with cotton-wool spots.
Article Synopsis
- The study discusses two cases of vasculitis (one with bleeding and one without) following uncomplicated cataract surgery that used intracameral vancomycin.
- Both patients experienced significant vision loss within two weeks after the surgery, leading to different types of vasculitis.
- Combining various corticosteroid treatments helped partially restore vision and prevented further complications in both cases, highlighting the importance of early diagnosis and treatment.
Purpose: To report the initial experience, clinical outcomes, and safety profile of 27 gauge pars plana vitrectomy (PPV) in eyes with posterior segment disease.
Design: Multicenter, retrospective, interventional case series.
Methods: setting: Private practice and tertiary care settings.
Combined 23-Gauge PPV and Scleral Buckle Versus 23-Gauge PPV Alone for Primary Repair of Pseudophakic Rhegmatogenous Retinal Detachment.
Ophthalmic Surg Lasers Imaging Retina
April 2016
Background And Objective: This review compares 23-gauge pars plana vitrectomy (PPV) alone versus combined 23-gauge pars plana vitrectomy and scleral buckle (PPV/SB) for primary repair of pseudophakic rhegmatogenous retinal detachment (RRD).
Patients And Methods: A retrospective review of 70 eyes that underwent 23-gauge PPV and 43 eyes that received 23-gauge PPV/SB for pseudophakic RRD. Minimum follow-up was 3 months.
Purpose: To determine whether topical aqueous suppressants affect the duration of pure expansile intraocular gas in nonvitrectomized eyes.
Methods: A prospective randomized controlled trial was performed on nonvitrectomized patients undergoing retinal detachment repair with scleral buckle or pneumatic retinopexy using 0.3 mL of 100% perfluoropropane (C3F8) gas tamponade.
Purpose: To evaluate the outcome of pars plana vitrectomy, subretinal tissue plasminogen activator (t-PA) infusion and intraocular gas tamponade with and without postsurgical antivascular endothelial growth factor (VEGF) injection for thick submacular hemorrhage due to exudative age-related macular degeneration (AMD).
Design: Retrospective, comparative, interventional case series.
Methods: setting: 2 retina referral centers.
Purpose: To describe the clinical characteristics of and risk factors for the development of optic neuropathy after pars plana vitrectomy (PPV) for macula-sparing primary rhegmatogenous retinal detachment (RRD) repair.
Design: Retrospective case-control study.
Participants: Seven patients who underwent PPV for macula-sparing primary RRD with subsequent development of optic neuropathy and 42 age- and gender-matched control patients undergoing PPV for macula-sparing primary RRD.
