Methods:
Inner limiting membrane specimens were harvested from 117 eyes of 117 patients during vitrectomy with mem…

Purpose:
In subretinal gene therapy for inherited retinal diseases (IRDs), blebs may not propagate predictably in the direction of the injection cannula. We evaluated factors that influenced bleb propagation among various IRDs.
Methods:
Retrospective review of all subretinal gene therapy procedures performed by a single surgeon between September 2018 and March 2020 for various IRDs. Main outcome measures were directional bias of bleb propagation and intraoperative foveal detachment.
Results:
Desired injection volumes and/or foveal treatment were successfully achieved in all 70 eyes of 46 patients with IRD regardless of IRD indication. Bullous foveal detachment was associated with retinotomy closer to the fovea, posterior bleb bias, and greater bleb volumes (P
Purpose:
Characterize clinical and socioeconomic factors that impact follow-up to complete retinal vascularization and subsequent pediatric ophthalmology follow-up in neonates with retinopathy of prematurity.
Methods:
Medical records of 402 neonates diagnosed with retinopathy of prematurity from neonatal intensive care units at the University of California, Los Angeles Mattel Children’s Hospital and the University of California, Los Angeles Santa Monica Hospital, both academic medical centers, and the Harbor-University of California, Los Angeles Medical Center, a safety-net county hospital, were reviewed. Primary study outcomes were the rate of follow-up to complete retinal vascularization and adequate pediatric ophthalmology follow-up. Secondary outcome was the rate of nonretinal ocular comorbidity.
Results:
In whole-cohort analysis, 93.6% of neonates were followed to complete retinal vascularization, and 53.5% had adequate pediatric ophthalmology follow-up. Public insurance was associated with lower rates of pediatric ophthalmology follow-up (Odds ratio 0.66, 95% confidence interval 0.45–0.98, P = 0.04). Participants screened at the academic medical center had lower rates of pediatric ophthalmology follow-up compared with the safety-net county hospital (50.7% vs. 63.5%, P = 0.034). In subgroup analysis, academic medical center participants with public insurance were less likely to have pediatric ophthalmology follow-up than safety-net county hospital participants with public insurance (36.5% vs. 63.8%, P
Purpose:
To evaluate the prevalence and risk factors for development of paravascular inner retinal defects (PIRDs) using en face optical coherence tomography.
Methods:
This is a retrospective cross-sectional study. En face and cross-sectional optical coherence tomography images were reviewed (9 × 9 mm or 12 × 12 mm). Paravascular inner retinal defects were classified as either Grade 1 (i.e., paravascular inner retinal cysts) when the lesion was confined within the nerve fiber layer without any communication to the vitreous cavity or Grade 2 (i.e., paravascular lamellar hole) when the defects communicated to the vitreous. Paravascular inner retinal defect grading was correlated with presence of high myopia, stage of posterior vitreous detachment, and presence of epiretinal membrane and retinoschisis.
Results:
Of 1,074 patients (2,148 eyes), PIRDs were detected in 261 eyes with a prevalence of 261 per 2,148 eyes (12.2%) and 176 per 1,074 patients (16.4%). A total of 116 eyes (44.4%) displayed Grade 2 PIRDs while 145 eyes (55.6%) were Grade 1. In the multivariate logistic regression model, the presence of partial/complete posterior vitreous detachment, retinoschisis, and epiretinal membrane was significantly correlated with PIRDs (OR = 2.78 [1.7–4.4], P
Purpose:
To evaluate microvascular and neuronal changes over 3 years in patients with Type 1/2 diabetes mellitus (DM1/DM2), good metabolic control, and no signs of diabetic retinopathy.
Methods:
In this prospective, longitudinal study, 20 DM1, 48 DM2, and 24 controls underwent macular optical coherence tomography and optical coherence tomography angiography at baseline and after 3 years. Following parameters were considered: thickness of the central macula, retinal nerve fiber layer, ganglion cell (GCL+/GCL++) complex; perfusion and vessel density and fractal dimension at the superficial and deep capillary plexuses; choriocapillaris flow deficits; and foveal avascular zone metrics. MATLAB and ImageJ were used for optical coherence tomography angiography scans analyses.
Results:
The mean HbA1c was 7.4 ± 0.8% in DM1 and 7.2 ± 0.8% in DM2 at baseline, with no change at 3 years. No eye developed diabetic retinopathy. In longitudinal analyses, perfusion density at superficial capillary plexuses (P = 0.03) and foveal avascular zone area and perimeter (P
Purpose:
The mean change in best-corrected visual acuity (BCVA), intraocular pressure, and endothelial cell counts after intraocular lens (IOL) implantation and the incidence rate of postoperative complications were estimated by systematic review and meta-analysis to assess the surgical and refractive outcomes of the sutureless scleral fixation Carlevale IOL.
Methods:
A literature search was conducted using PubMed, Embase, and Scopus. The weighted mean difference (WMD) was used to present the mean change in BCVA, intraocular pressure, and endothelial cell count after IOL implantation, whereas a proportional meta-analysis was used to estimate the pooled incidence rate of postoperative complications.
Results:
In the meta-analysis of 13 studies involving 550 eyes, the pooled WMD of the mean change in BCVA showed a significant improvement in BCVA in patients who underwent Carlevale IOL implantation (WMD = 0.38, 95% confidence interval: 0.30–0.46, P

Purpose:
Long-acting injectable steroids are changing the treatment paradigm for patients with chronic intraocular inflammation and cystoid macular edema (CME). We report the use of the fluocinolone implant 0.18 mg in patients with chronic postsurgical CME after pars plana vitrectomy.
Methods:
This is a retrospective case series of 24 vitrectomized eyes which received fluocinolone implant for the management postsurgical CME. Clinical outcomes and requirement for rescue therapy were studied.
Results:
Median length of follow-up was 19.3 months (range 8.3–23.2 months). There was an improvement in median central subfield thickness from 412 µm (range 167–806 µm) to 311 µm (range 157–686 µm) after fluocinolone implant (P
