Purpose: To compare 2 mg intravitreal triamcinolone (IVT) versus 40 mg posterior sub-Tenon triamcinolone acetonide (STT) for the treatment of eyes with pseudophakic cystoid macular edema.
Methods: A retrospective, single-center review of eyes receiving 2 mg IVT between 3/1/2012-3/1/2017 and 40 mg STT between 1/1/2015-3/1/2017. Visual acuity (VA) and central macular thickness (CMT) were recorded at baseline, 1-, 3-, and 6-month follow-up visits.
Purpose: To compare anatomic and functional outcomes in eyes with proliferative diabetic retinopathy (PDR) that were lost to follow-up (LTFU) for more than 6 months after treatment with either intravitreal injection (IVI) of anti-vascular endothelial growth factor (VEGF) agents or panretinal photocoagulation (PRP).
Design: Retrospective cohort study.
Participants: Fifty-nine patients who were LTFU immediately after treatment for more than 6 months between September 2013 and September 2016.
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 compare fluid detection of autosegmented en face to 12-line radial spectral domain optical coherence tomography scan patterns in neovascular age-related macular degeneration.
Methods: Retrospective observational case series. Sixty-seven patients (94 eyes) with neovascular age-related macular degeneration underwent autosegmented en face optical coherence tomography (with associated 304-line raster scan) and 12-line radial scan patterns.
Purpose: To quantify foveal avascular zone (FAZ) area and macular vascular density objectively using optical coherence tomography angiography (OCTA) and to examine correlations with visual acuity in eyes with diabetic retinopathy (DR) in the absence of diabetic macular edema.
Design: Retrospective observational case series.
Participants: Eighty-four eyes from 55 patients with DR and 34 control eyes from 27 age-matched healthy participants.
Purpose: To assess comfort and procedural facility using a 25-gauge trocar cannula as a port to diagnose and treat acute endophthalmitis compared with a standard vitreous tap and injection technique.
Methods: Eighteen consecutive patients with acute endophthalmitis were randomized into two treatment arms: 1) Standard vitreous tap and injection technique, and 2) A technique where a valved 25-gauge trocar cannula is inserted through the pars plana as done in sutureless vitrectomy surgery and subsequent vitreous sampling and injections are performed through the port. A standardized anesthetic protocol was used and subjects were masked to the technique performed.
Objective: To describe the clinical features and management of six patients with ocular complications associated with direct oral anticoagulants (DOACs).
Methods: The medical records of all adult patients known to be taking a DOAC and with an unusual bleeding event at a large tertiary referral center over a one-year period were reviewed. Patients with less than one-month follow-up were excluded.
Purpose: To evaluate the short-term functional and anatomic outcomes of patients with persistent diabetic macular edema (DME) who were converted from bevacizumab and/or ranibizumab to aflibercept.
Design: Retrospective, interventional, noncomparative, consecutive case series.
Methods: Only eyes treated with at least 4 consecutive injections of ranibizumab/bevacizumab spaced 4-6 weeks apart prior to conversion and with at least 2 aflibercept injections afterward were considered for inclusion.
Purpose: To investigate the effect of serial intrasilicone oil bevacizumab injections (1.25 mg/0.05 mL) on visual acuity (VA) and anatomic outcomes in eyes undergoing proliferative vitreoretinopathy (PVR)-related retinal detachment (RD) repair.

Design: Retrospective observational case series.
Methods: Clinical histories, high-resolution digital color imaging, spectral-domain OCT images, fluorescein angiography, OCT angiography images, and en face OCT images of 16 patients with paracentral acute middle maculopathy were evaluated.
Objective: To describe visual and anatomical outcomes following bi-weekly intravitreal ranibizumab/bevacizumab injections in eyes with refractory neovascular age-related macular degeneration (AMD) and pigment epithelial detachment (PED).
Design: Retrospective, consecutive, interventional case series.
Participants: Eighteen patients diagnosed with neovascular AMD that were refractory to anti-VEGF therapy and received alternating biweekly ranibizumab/bevacizumab injections were included.
Background/aims: To compare the 12-line radial to the 25-line raster spectral-domain optical coherence tomography (SD-OCT) acquisition patterns at detecting intraretinal or subretinal fluid in eyes with neovascular age-related macular degeneration (AMD).
Methods: Retrospective cross-sectional analysis of 200 eyes with neovascular AMD. Sequential 12-line radial and 25-line raster scans were evaluated for the presence of intraretinal/subretinal fluid.
Purpose: To determine the generalizability of recent data assessing the necessity of ophthalmic consultation for fungemic patients, we examined the prevalence, microbial profile, and treatment of fungal chorioretinitis and endophthalmitis among patients with positive fungal cultures referred for ophthalmologic consultation at a tertiary care medical center.
Design: Retrospective cross-sectional study.
Methods: All inpatient ophthalmology consultations from Wills Eye Hospital at Thomas Jefferson University between January 1, 2006 and December 31, 2012 were retrospectively reviewed and cross-referenced to a microbiologic database of positive fungal blood cultures.
Serous retinal detachment (SRD) can be the initial manifestation of leukemia. Herein, we explore the retinal and choroidal features on enhanced depth imaging optical coherence tomography (EDI-OCT) of SRD in a patient with undiagnosed leukemia. A 23-year-old male developed blurred visual acuity of 20/200 in the right eye oculus dexter (OD) and 20/200 in the left eye oculus sinister (OS).

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 compare the 6-line radial vs the 25-line raster spectral-domain optical coherence tomography (SD OCT) acquisition patterns at detecting intraretinal fluid, subretinal fluid, vitreomacular traction, and full-thickness macular hole (MH).
Design: Retrospective cross-sectional analysis.
Methods: Series of 365 eyes with neovascular age-related macular degeneration (AMD), diabetic macular edema (DME), central and branch retinal vein occlusion (CRVO/BRVO), central serous chorioretinopathy, vitreomacular traction, and full-thickness MH.
Objective: To determine the long-term safety of pars plana vitrectomy (PPV) in eyes with plaque-irradiated posterior uveal melanoma.
Methods: In this retrospective case series, patients with plaque-irradiated posterior uveal melanoma subsequently underwent PPV for vitreous hemorrhage. The main outcome measures are the rates of intraocular melanoma dissemination, extrascleral extension of melanoma, local melanoma recurrence, and systemic melanoma metastasis after PPV.
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.
Purpose: To report 10 cases of occult choroidal neovascularization (CNV) associated with choroidal nevus managed with intravitreal bevacizumab.
Methods: Interventional case series. Each nevus was examined and imaged with fluorescein angiography, B-scan ultrasonography, and optical coherence tomography.
