A Cost Effectiveness Analysis of Avacincaptad Pegol for the Treatment of Geographic Atrophy with Comparison to Pegcetacoplan. Ophthalmol Retina 2024:S2468-6530(24)00238-0. [PMID: 38777140 DOI: 10.1016/j.oret.2024.05.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2024] [Revised: 04/18/2024] [Accepted: 05/13/2024] [Indexed: 05/25/2024]
Abstract
PURPOSE To evaluate the cost-effectiveness of the treatment of geography atrophy (GA) with intravitreal avacincaptad pegol (ACP) and to compare it to pegcetacoplan (PEG). DESIGN Cost analysis based on data from published studies. SUBJECTS None; based on data from published sham control compared with 2 treatment groups in each of the index studies. METHODS Costs were based on 2022 Medicare reimbursement data for both facility (hospital-based) and nonfacility settings in Miami. Specific usage and outcomes were derived from the GATHER2 study as well as DERBY and OAKS trials. For ACP, all patients were treated EM in year 1 then randomized to EOM or EM in year 2. Two-year models were created for patients in the facility setting for extrafoveal (ACP and PEG) and all patients (PEG). OUTCOME MEASURES Cost, cost utility, and cost per area of GA (in US$). RESULTS The cost to treat GA with ACP in every month (EM) and every other month (EOM) treatment groups over the 2 years as reported was $67,400 and $40,600, respectively. With ACP treatment over 2 years, the daily cost of delaying GA 3.4 months (EM) and 4.5 months (EOM) was $649 (EM) and $356 (EOM). The (facility-based) costs per unit area of RPE saved for extrafoveal GA patients over the two-year period were $119,000/mm2 (EM ACP) vs. $54,000/mm2 (EM PEG) (P<0.001), $57,100/mm2 (EOM ACP) vs. $31,400/mm2 (EOM PEG) (P<0.001), and $45,300/mm2 (hypothetical EOM from outset ACP). CONCLUSION Treatment of GA with intravitreal ACP EOM was more cost effective than EM. When assessing extrafoveal lesions, ACP was less cost effective than PEG for both EM and EOM treatment.

Abstract
PURPOSE To evaluate features of infectious panuveitis associated with multiple pathogens detected by ocular fluid sampling. METHODS Single-center, retrospective, consecutive case series of patients with aqueous/vitreous polymerase chain reaction testing with >1 positive result in a single sample from 2001 to 2021. RESULTS Of 1,588 polymerase chain reaction samples, 28 (1.76%) were positive for two pathogens. Most common pathogens were cytomegalovirus (n = 16, 57.1%) and Epstein-Barr virus (n = 13, 46.4%), followed by varicella zoster virus (n = 8, 28.6%), Toxoplasma gondii (n = 6, 21.4%), herpes simplex virus 2 (n = 6, 21.4%), herpes simplex virus 1 (n = 6, 21.4%), and Toxocara (n = 1, 3.6%). Mean initial and final visual acuity (logarithm of the minimum angle of resolution) were 1.3 ± 0.9 (Snellen ∼20/400) and 1.3 ± 1.1 (Snellen ∼20/400), respectively. Cytomegalovirus-positive eyes (n = 16, 61.5%) had a mean final visual acuity of 0.94 ± 1.1 (Snellen ∼20/175), whereas cytomegalovirus-negative eyes (n = 10, 38%) had a final visual acuity of 1.82 ± 1.0 (Snellen ∼20/1,320) ( P < 0.05). Main clinical features included intraocular inflammation (100%), retinal whitening (84.6%), immunosuppression (65.4%), retinal hemorrhage (38.5%), and retinal detachment (34.6%). CONCLUSION Cytomegalovirus or Epstein-Barr virus were common unique pathogens identified in multi-PCR-positive samples. Most patients with co-infection were immunosuppressed with a high rate of retinal detachment and poor final visual acuity. Cytomegalovirus-positive eyes had better visual outcomes compared with cytomegalovirus-negative eyes.

Phylogenetic and Recombination Analysis of Clinical Vitreous Humor-Derived Adenovirus Isolates Reveals Discordance Between Serotype and Phylogeny. Invest Ophthalmol Vis Sci 2024; 65:12. [PMID: 38319669 PMCID: PMC10854415 DOI: 10.1167/iovs.65.2.12] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Accepted: 01/19/2024] [Indexed: 02/07/2024] Open
Abstract
Purpose To sequence, identify, and perform phylogenetic and recombination analysis on three clinical adenovirus samples taken from the vitreous humor at the Bascom Palmer Eye Institute. Methods The PacBio Sequel II was used to sequence the genomes of the three clinical adenovirus isolates. To identify the isolates, a full genome-based multiple sequence alignment (MSA) of 722 mastadenoviruses was generated using multiple alignment using fast Fourier transform (MAFFT). MAFFT was also used to generate genome-based human adenovirus B (HAdV-B) MSAs, as well as HAdV-B fiber, hexon, and penton protein-based MSAs. To examine recombination within HAdV-B, RF-Net 2 and Bootscan software programs were used. Results In the course of classifying three new atypical ocular adenovirus samples, taken from the vitreous humor, we found that all three isolates were HAdV-B species. The three Bascom Palmer HAdV-B genomes were then combined with over 300 HAdV-B genome sequences, including nine ocular HAdV-B genome sequences. Attempts to categorize the penton, hexon, and fiber serotypes using phylogeny of the three Bascom Palmer samples were inconclusive due to incongruence between serotype and phylogeny in the dataset. Recombination analysis using a subset of HAdV-B strains to generate a hybridization network detected recombination between nonhuman primate and human-derived strains, recombination between one HAdV-B strain and the HAdV-E outgroup, and limited recombination between the B1 and B2 clades. Conclusions The discordance between serotype and phylogeny detected in this study suggests that the current classification system does not accurately describe the natural history and phylogenetic relationships among adenoviruses.

Abstract
PURPOSE To report the use of intravitreal triamcinolone to treat macular edema associated with isolated perifoveal exudative vascular anomalous complex (PVAC) and resembling lesion (PVAC-RL). METHODS In this case series, three diabetic patients (3 eyes) with PVAC-RLs and one healthy patient (1 eye) with PVAC lesion associated with cystic spaces underwent three intravitreal injections of aflibercept before switching to one intravitreal triamcinolone injection in each patient. RESULTS Macular edema improved from 297.5 ± 8.10 μm, at baseline, to 269.2 ± 8.89 μm, after triamcinolone; whereas visual acuity improved from 20/38 to 20/26 (ETDRS). CONCLUSION PVAC and PVAC-RL are rare and often misdiagnosed lesions that may be associated with decreased vision. Our outcomes suggest that intravitreal injection of triamcinolone may be an effective and affordable treatment for PVAC and PVAC-RL with intraretinal fluid.

Abstract
PURPOSE To report bilateral retinal vascular occlusive disease in limb-girdle muscular dystrophy (LGMD). METHODS Case report. RESULTS A 34-year-old Asian woman was referred for evaluation and management of central retinal vein occlusion. Ultra-wide-field fluorescein angiography showed resolving initial peripheral retinal vein occlusion in one eye and peripheral venular segmental staining in the fellow asymmetric eye. Genetic testing established the diagnosis of LGMD. CONCLUSION Similar to other forms of muscular dystrophy, LGMD is caused by genetic abnormalities in sarcolemma proteins, a key structural component that connects the intracellular cytoskeleton of a myofiber to the extracellular matrix. Like other muscular dystrophies, LGMD may be associated with retinal vascular abnormalities noted. In this case, retinal vascular smooth muscle dysfunction was seen in LGMD, analogous to reported vascular abnormalities in other muscular dystrophies such as facioscapulohumeral dystrophy and Duchenne muscular dystrophy.

Abstract
PURPOSE To evaluate the cost-effectiveness of the treatment of geography atrophy (GA) with intravitreal pegcetacoplan and to identify utility-measurement surrogates. DESIGN Cost analysis based on data from a published study. SUBJECTS None; based on data from published sham control compared with 2 treatment groups in the index study. METHODS Costs were based on 2022 Medicare reimbursement data. Specific outcomes were extrapolated from the DERBY and OAKS trials. Assumptions were made for the lifetime analysis based on a theoretical logistic growth model of the atrophy. OUTCOME MEASURES Cost, cost utility, cost per quality-adjusted life-year, and cost per area of GA (in US$). RESULTS The costs to treat GA in every month (EM) and every-other-month (EOM) treatment groups over the 2 years as reported were $70 000 and $34 600, respectively. The costs per area of delaying GA for 2 years in all patients were $87 300/mm2 (EM) and $49 200/mm2 (EOM), and in initially extrafoveal patients, $53 900/mm2 (EM) and $32 100/mm2 (EOM). The costs per day of delaying GA for 2 years were $295 (EM) and $170 (EOM); the marginal cost (EM vs. EOM) per retinal pigment epithelium cell saved was $30. The modeled lifetime costs were $350 000 (EM) and $172 000 (EOM), or $309 000/mm2 (EM) and $180 000 (EOM) /mm2. The modeled time to 95% atrophy at 13 years was delayed by 2.5 years (EM) and 2.1 years (EOM). The costs/quality-adjusted life-year gained based on modeled visual loss with 95% atrophy were $706 000 (EM) and $397 000 (EOM). CONCLUSION Treatment of GA with intravitreal pegcetacoplan EOM was more cost effective than EM. Treatment of extrafoveal lesions yielded greater utility than the treatment of the entire group. As atrophy progression approaches an upper limit, the marginal cost/benefit ratios increase.

Endophthalmitis caused by Burkholderia cepacia complex (BCC): clinical characteristics, antibiotic susceptibilities, and treatment outcomes. J Ophthalmic Inflamm Infect 2023; 13:48. [PMID: 37922028 PMCID: PMC10624773 DOI: 10.1186/s12348-023-00370-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2023] [Accepted: 10/15/2023] [Indexed: 11/05/2023] Open
Abstract
PURPOSE To report the clinical characteristics, antibiotic susceptibilities, and review the literature of Burkholderia cepacia complex (BCC) associated endophthalmitis. STUDY DESIGN Retrospective, observational case series. METHODS Clinical and microbiology records were reviewed for patients evaluated at the Bascom Palmer Eye Institute and diagnosed wisth culture-confirmed endophthalmitis due to BCC. Antibiotic susceptibility profiles were generated using standard microbiologic protocols via an automated VITEK system. RESULTS Endophthalmitis associated with BCC was diagnosed in three patients. Infection occurred in the setting of post-penetrating keratoplasty (PKP), glaucoma filtering surgery, and suspected trauma. All isolates demonstrated in vitro susceptibility to ceftazidime and meropenem. Presenting visual acuity (VA) ranged from hand motion to light perception. Initial treatment strategies included intravitreal ceftazidime (2.25 mg/0.1 mL) and vancomycin (1.0 mg/0.1 mL) injections with fortified topical antibiotics in 2 patients, and surgical debridement of a corneoscleral melt with patch graft along with both topical fortified antibiotics oral antibiotics in the third patient. In all 3 patients, there was no VA improvement at last follow-up, as 2 eyes ultimately underwent enucleation and 1 eye exhibited phthisis bulbi at last follow-up. BCC related endophthalmitis was reviewed among 13 reports. Treatment outcomes were generally poor and antibiotic resistance was common. These BCC isolates cases demonstrated broad resistance patterns, with susceptibilities to ceftazidime (58%), ciprofloxacin (53%), and gentamicin (33%). CONCLUSIONS Endophthalmitis caused by B. cepacia is a rare clinical entity with generally poor visual outcomes despite prompt treatment with appropriate antibiotics.

Abstract
PURPOSE To report the trends of immunosuppressive drug use for non-infectious uveitis and explore their relationship with industry payments. METHODS A retrospective review of ophthalmologists reimbursed by Medicare for the administration of adalimumab (ADA), repository corticotropin (RCI), methotrexate (MTX), and mycophenolate mofetil (MMF) between 2014 and 2018. RESULTS A total of 316 ophthalmologists were reimbursed by Medicare for 1567 ADA, 465 RCI, 1752 MTX, and 12 333 MMF administrations. The number and dollar amount of industry payments were positively associated with ADA and RCI use (P < 0.001). From 2014 to 2018, there was a positive trend in the proportion of ADA (P = 0.007) and RCI (P = 0.007) used and negative trend in the proportion of MMF (P = 0.025) used. CONCLUSION From 2014 to 2018, the use of ADA and RCI increased while MMF decreased and MTX remained stable. There was a positive association between ADA and RCI use and physician-industry interactions. A causal relationship is not determined.

Abstract
The availability of direct-to-consumer genetic testing (DTCGT) for age-related macular degeneration (AMD) provides the public with access to disease risk estimations that may be used to guide lifestyle adjustments. However, AMD development risk is more complex than can be captured by gene mutations alone. The methodologies employed by current DTCGTs to estimate AMD risk vary and are limited in several ways. Genotyping-based DTCGT is biased toward European ancestry and only considers a limited number of genes. Whole genome sequencing based DTCGTs uncovers several genetic variations with unknown relevance, making risk interpretation challenging. In this perspective, we describe the limitations of the DTCGT for AMD.

Abstract
BACKGROUND/PURPOSE Within the evolving landscape of healthcare in the United States (US), delineating the demographic nuances and financial implications of emergent conditions, such as rhegmatogenous retinal detachment (RRD), is paramount. This study seeks to analyze the demographic and hospital billing amount/cost of service disparities in RRD visits to emergency departments (EDs) nationwide. METHODS We conducted a retrospective, cross-sectional, population-based study using International Classification of Diseases, 10th revision , and Current Procedural Terminology codes in the 2016 to 2019 Nationwide Emergency Department Sample databases to identify RRD visits. The analysis included demographics, hospital billing amount, and cost of service of RRD ED management. RESULTS A total of 12,492 RRD encounters were identified with men constituting 64% and a prominent age group being 50 to 64 years (49.3%). Most patients (90%) were managed in metropolitan teaching hospitals, predominantly in the southern U.S. region (56.1%). Private insurance covered 45% of patients. Same-day RRD repair odds increased in November and December. Whites had a higher likelihood for same-day treatment. Hospital billing amount rose from $23,600 in 2016 to $30,354 in 2019, with stable mean total cost of service. Rhegmatogenous retinal detachment ED visit incidence did not show seasonal variation ( P = 0.819). CONCLUSION Most patients with RRD in U.S, EDs were middle-aged men, with Whites more likely to receive same-day repair. There was no sex bias observed in same-day repair decision-making. Although hospital billing amount increased over the study period, total cost of service remained stable. The incidence of RRD ED visits showed no seasonal variation.

Abstract
Purpose: To investigate the clinical outcome of cystoid macular edema (CME) in eyes undergoing silicone oil (SO) tamponade with subsequent SO removal (SOR). Methods: A retrospective case series of adult patients with CME treated with SO tamponade and SOR was conducted between January 2015 and January 2021. Exclusion criteria included eyes with a prior SO tamponade, those that did not undergo SOR, or those with infectious/inflammatory diagnoses. The primary outcomes were the incidence and resolution rates of CME in eyes with SO tamponade that had undergone SOR. The secondary outcomes included changes in best-corrected visual acuity (BCVA) and central field thickness (CFT). Results: Nineteen eyes of 19 patients (58% men) aged 52 years (interquartile range [IQR], 45-66 years) met the study inclusion criteria. The median (IQR) follow-up duration post SOR was 22 (8-35) months. The mean CFT decline for the CME-resolved cases was 13.1 µm/mo (P = .257). CME resolved in only 10 eyes (53%), 7 (67%) of which occurred after SOR. The median (IQR) BCVA was 20/400 (20/200 to 20/1262) at CME diagnosis and 20/796 (20/252 to hand motions) after SOR, with 0.184 worsening in logMAR BCVA (P = .340). Medical treatment was not associated with CME resolution compared with observation (50% vs 89%, respectively; P = .069). Eyes with proliferative vitreoretinopathy (PVR) had a higher rate of persistent CME compared with eyes with other diagnoses (78% vs 10%, respectively; P = .005). Conclusions: Nearly half had nonresolution of CME after SO was removed. The VA at the last follow-up was unaffected by CME resolution. Preoperative PVR may be a risk factor for unresolved CME.

Abstract
INTRODUCTION An 18-year old highly myopic woman presented with bilateral retinoschisis associated with a unilateral macular hole in the right eye and vitreomacular traction in the left eye. METHODS Genetic studies disclosed a heterozygous pathogenic variant in the KCNJ13 gene was identified (c.484C>T (p.Arg162Trp)), consistent with a diagnosis of snowflake vitreoretinal degeneration (SVD). RESULTS While there were no corneal guttata, juvenile cataracts, or perivascular sheathing in this case, salient features of SVD included a fibrillar vitreous structure, crystalline retinopathy, and flattened optic nerves. The patient developed a FTMH in the left eye at 17 months follow up, followed by a rhegmatogenous retinal detachment (RRD) requiring 2 surgical repairs. CONCLUSION This case expands on the spectrum of clinical features in SVD, including retinoschisis and FTMH. It also characterizes optical coherence tomography findings in this rare disease entity. We emphasize the importance of using panel-based genetic testing to clinically distinguish and further define atypical vitreoretinopathies.

Abstract
BACKGROUND AND OBJECTIVE Retinal detachments (RDs) are a complication of X-linked retinoschisis (XLRS) with a poor prognosis. This study aims to report outcomes of XLRS-RD repair in pediatric patients. MATERIALS AND METHODS The study is a retrospective analysis of pediatric patients undergoing vitreoretinal surgery for XLRS-RDs from 2000 to 2022. RESULTS Nine patients (11 eyes) met inclusion criteria. All patients were boys, with a mean age of 8 years. Most RDs arose inferiorly (64%). Seven (64%) detachments were macula-involving. Seven (64%) detachments were repaired with combined scleral buckling and vitrectomy, two (18%) detachments were repaired with vitrectomy alone, one (9%) detachment underwent a primary scleral buckling procedure, and one (9%) asymptomatic detachment with a pigment demarcation line was observed. Silicone oil was used in eight of nine (89%) eyes undergoing vitrectomy. Final visual acuity was 20/200 or better in eight (73%) eyes. One eye that underwent surgical intervention remained unattached at follow-up. CONCLUSION Surgical repair in patients with XLRSRDs was associated with successful reattachment, although visual prognosis varied. [Ophthalmic Surg Lasers Imaging Retina 2023;54:574-579.].

Abstract
PURPOSE We evaluated the clinical outcomes of intraocular inflammation (IOI) of eyes with neovascular age-related macular degeneration (AMD) injected with brolucizumab in our tertiary referral center. METHODS A retrospective case series for which clinical records of all eyes that received intravitreal brolucizumab at Bascom Palmer Eye Institute between December 1, 2019, and April 1, 2021, were reviewed. RESULTS There were 345 eyes of 278 patients who received 801 brolucizumab injections. IOI was detected in 16 eyes of 13 patients (4.6%). In those patients, baseline Logarithm of Minimu Angle of Resolution (logMAR) best-corrected visual acuity was 0.32 0.2 (20/42), while it was 0.58 0.3 (20/76) at IOI presentation. The mean number of injections among eyes experiencing IOI was 2.4, and the interval between the last brolucizumab injection and IOI presentation was 20 days. There was no known case of retinal vasculitis. Management of IOI included topical steroids in seven eyes (54%), topical and systemic steroids in five eyes (38%), and observation in one eye (8%). Best-corrected visual acuity returned to baseline and inflammation resolved in all eyes by the last follow-up examination. CONCLUSION Intraocular inflammation after brolucizumab injection for neovascular AMD was not uncommon. Inflammation resolved in all eyes by the last follow-up visit.

Acute serous and hemorrhagic choroidal effusion associated with topical dorzolamide therapy. Am J Ophthalmol Case Rep 2023; 31:101866. [PMID: 37323588 PMCID: PMC10265454 DOI: 10.1016/j.ajoc.2023.101866] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2023] [Revised: 05/10/2023] [Accepted: 05/24/2023] [Indexed: 06/17/2023] Open
Abstract
Purpose To report a case of acute onset unilateral hemorrhagic and serous choroidal effusion associated with dorzolamide administration and antiplatelet use that recurred in a patient who experienced a dorzolamide-induced choroidal effusion ten years prior to presentation. Observations A 78-year-old male with a history of POAG in both eyes presented with sudden onset decreased vision and flashes of light in the left eye two days after escalating from timolol maleate 0.5% twice daily in both eyes to fixed combination dorzolamide-timolol 22.3-6.8 mg/mL twice daily in both eyes. Systemic medication included daily aspirin 81 mg for primary prevention of cardiovascular disease. Dilated fundus examination and B-scan ultrasound of the left eye revealed a hemorrhagic choroidal effusion in the nasal retinal periphery and low lying serous choroidal effusion in the temporal periphery. Complete resolution of the choroidal detachment was achieved in four days following prompt cessation of dorzolamide, and treatment with topical prednisolone acetate 1% four times daily and atropine 1% two times daily. Conclusions and importance Topical dorzolamide may induce an idiosyncratic reaction leading to serous and hemorrhagic choroidal effusion, which can be exacerbated by antiplatelet use. Prompt recognition and management of drug-induced choroidal effusion can lead to improved visual outcomes and prevent long-term sequelae.

Retinopathy of Prematurity Outcomes of Neonates Meeting Only a Single Screening Criterion: Proposal of the TWO-ROP Algorithm. Am J Ophthalmol 2023; 252:147-152. [PMID: 36933856 DOI: 10.1016/j.ajo.2023.03.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2022] [Revised: 02/28/2023] [Accepted: 03/05/2023] [Indexed: 03/18/2023]
Abstract
PURPOSE To assess the rates of retinopathy of prematurity (ROP) and treatment-warranted ROP in a modern set of patients meeting 0 or 1 of the current ROP screening criteria. DESIGN Retrospective cohort study. METHODS Single-center study of 9350 infants screened for ROP from 2009 to 2019. Rates of ROP and treatment-warranted ROP were evaluated in group 1 (birth weight [BW] <1500 g and gestational age [GA] ≥30 weeks), group 2 (BW ≥1500 g and GA <30 weeks), and group 3 (BW ≥1500 g and GA ≥30 weeks). RESULTS Of 7520 patients with reported BW and GA, 1612 (21.4%) patients met the inclusion criteria. The number of patients in groups 1, 2, and 3 was 466 (6.19%), 23 (0.31%), and 1123 (14.93%), respectively. The number of patients diagnosed with ROP was 20 (4.29%) in group 1, 1 (4.35%) in group 2, and 12 (1.07%) in group 3 (P < .001). The mean interval between birth and ROP diagnosis was 36.25 days (range 12-75 days) in group 1, 47 days in group 2, and 23.33 days (range 10-39 days) in group 3 (P = .05). No cases of stage 3, zone 1, or plus disease were recorded. No patients met the treatment criteria. CONCLUSIONS Patients meeting 1 screening criterion had a low rate of ROP (<5%), with no stage 3, zone 1, or plus disease. No patients required treatment. We propose a possible algorithm (TWO-ROP) in appropriate neonatal intensive care units, with an amendment in screening protocol for this low-risk population to include only an outpatient screening examination within 1 week of discharge, or at 40 weeks if inpatient, to decrease the inpatient ROP screening burden while maintaining safety. Further external validation of this protocol would be required.

Abstract
PURPOSE To report the clinical presentation and outcomes in patients with Valsalva retinopathy. METHODS This was a retrospective case series of patients diagnosed with Valsalva retinopathy between June 1, 2010, and May 31, 2020. Clinical notes, operative reports, fundus photography, and optical coherence tomography images were reviewed. RESULTS This study comprised 58 eyes of 58 patients. The most common causes were lifting (34.4%), vomiting (20.6%), straining (20.6%), and coughing (17.2%). Mean best-corrected visual acuity at diagnosis was 20/163. The most frequently involved vitreoretinal compartment was the subhyaloid space (42.3%) followed by the intraretinal (32.7%), intravitreal (23.1%), and subretinal (13.4%) spaces. Mean best-corrected visual acuity of all patients was 20/59 at 3 months, 20/48 at 6 months, and 20/22 at 1 year. Mean time to clearance of hemorrhage on clinical examination was 99.0 ± 18.7 days in patients who underwent observation and 4.5 ± 3.5 days after surgery in patients who received pars plana vitrectomy. CONCLUSION Valsalva retinopathy is generally associated with a favorable visual prognosis. Most eyes perform well with observation although pars plana vitrectomy may be indicated in patients requiring rapid resolution of hemorrhage.

Abstract
Purpose To report the clinical characteristics, antibiotic susceptibilities, and review the literature of Burkholderia cepacia complex (BCC) associated endophthalmitis. Study design Retrospective, observational case series. Methods Clinical and microbiology records were reviewed for patients evaluated at the Bascom Palmer Eye Institute and diagnosed with culture-confirmed endophthalmitis due to BCC. Antibiotic susceptibility profiles were generated using standard microbiologic protocols via an automated VITEK system. Results Endophthalmitis associated with BCC was diagnosed in three patients. Infection occurred in the setting of post-penetrating keratoplasty (PKP), glaucoma filtering surgery, and suspected trauma. All isolates demonstrated in vitro susceptibility to ceftazidime and meropenem. Presenting visual acuity (VA) ranged from hand motion to light perception. Initial treatment strategies included intravitreal ceftazidime (2.25 mg/0.1 mL) and vancomycin (1.0 mg/0.1mL) injections with fortified topical antibiotics in 2 patients, and surgical debridement of a corneoscleral melt with patch graft along with both topical fortified antibiotics oral antibiotics in the third patient. In all 3 patients, there was no VA improvement at last follow-up, as 2 eyes ultimately underwent enucleation and 1 eye exhibited phthisis bulbi at last follow-up. BCC related endophthalmitis was reviewed among 13 reports. Treatment outcomes were generally poor and antibiotic resistance was common. These BCC isolates cases demonstrated broad resistance patterns, with susceptibilities to ceftazidime (58%), ciprofloxacin (53%), and gentamicin (33%). Conclusions Endophthalmitis caused by B. cepacia is a rare clinical entity with generally poor visual outcomes despite prompt treatment with appropriate antibiotics.

Abstract
Purpose There are limited data on the prevalence and genetic diversity of herpes simplex virus type 1 (HSV-1) virulence genes in ocular isolates. Here, we sequenced 36 HSV-1 ocular isolates, collected by the Bascom Palmer Eye Institute, a university-based eye hospital, from three different ocular anatomical sites (conjunctiva, cornea, and eyelid) and carried out a genomic and phylogenetic analyses. Methods The PacBio Sequel II long read platform was used for genome sequencing. Phylogenetic analysis and genomic analysis were performed to help better understand genetic variability among common virulence genes in ocular herpetic disease. Results A phylogenetic network generated using the genome sequences of the 36 Bascom Palmer ocular isolates, plus 174 additional strains showed that ocular isolates do not group together phylogenetically. Analysis of the thymidine kinase and DNA polymerase protein sequences from the Bascom Palmer isolates showed multiple novel single nucleotide polymorphisms, but only one, BP-K14 encoded a known thymidine kinase acyclovir resistance mutation. An analysis of the multiple sequence alignment comprising the 51 total ocular isolates versus 159 nonocular strains detected several possible single nucleotide polymorphisms in HSV-1 genes that were found significantly more often in the ocular isolates. These genes included UL6, gM, VP19c, VHS, gC, VP11/12, and gG. Conclusions There does not seem to be a specific genetic feature of viruses causing ocular infection. The identification of novel and common recurrent polymorphisms may help to understand the drivers of herpetic pathogenicity and specific factors that may influence the virulence of ocular disease.

Abstract
Purpose: To evaluate the visual outcomes with unexplained vision loss during or after silicone oil (SO) tamponade. Methods: This multicenter retrospective case series comprised patients with unexplained vision loss associated with SO tamponade or its removal. Eyes with other clear secondary identifiable causes of vision loss were excluded. Results: Twenty-nine eyes of 28 patients (64% male) were identified. The mean age was 50 ± 13 years (range, 13-78 years). The mean duration of SO tamponade was 148 ± 38 days. Eighteen eyes (62%) developed unexplained vision loss while under SO; 11 (38%) had vision loss after SO removal. The most common optical coherence tomography (OCT) finding was ganglion cell layer (GCL) thinning (55%). Eyes with vision loss after SO removal had a mean logMAR best-corrected visual acuity (BCVA) of 0.6 ± 0.7 (Snellen 20/85) before SO tamponade and 1.2 ± 0.4 (20/340) before SO removal. By the last follow-up after SO removal, the BCVA had improved to 1.1 ± 0.4 (20/235). In eyes with vision loss after SO removal, the BCVA before SO removal was 0.7 ± 0.7 (20/104), which deteriorated to 1.4 ± 0.4 (20/458) 1 month after SO removal. By the last follow-up, the BCVA had improved to 1.0 ± 0.5 (20/219). Conclusions: Unexplained vision loss can occur during SO tamponade or after SO removal. Vision loss was associated with 1000-centistoke and 5000-centistoke oil and occurred in macula-off and macula-on retinal detachments. The duration of tamponade was 3 months or longer in the majority of eyes. Most eyes had GCL thinning on OCT. Gradual visual recovery can occur yet is often incomplete.

Abstract
Purpose: To describe a case of microcephaly, unilateral retinal fold, and familial exudative vitreoretinopathy (FEVR)-like phenotype in the context of 2 TUBGCP6 variants. Methods: A case and its findings were analyzed. Results: A 4-month-old boy with no family history of eye disease presented by referral for management of presumed persistent fetal vasculature in the left eye. An external examination showed microcephaly. The patient grimaced to light in both eyes, and the anterior segments were unremarkable. On dilated fundus examination, diffuse chorioretinal atrophy was present bilaterally. In the left eye, a retinal fold emanated from the optic nerve head. There was early termination of retinal vasculature, especially in zone 3 in the left eye, resembling a FEVR-like phenotype. Panel-based genetic testing was performed and found 2 mutations in TUBGCP6. Conclusions: Microcephaly, chorioretinopathy, and retinal folds may be associated with TUBGCP6 mutations and masquerade as PFV.

Aflibercept Monotherapy versus Bevacizumab-First for Diabetic Macular Edema: A Cost Analysis Based on Diabetic Retinopathy Clinical Research Network Protocol AC Results. Ophthalmol Retina 2023; 7:413-419. [PMID: 36423893 DOI: 10.1016/j.oret.2022.11.010] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2022] [Revised: 11/14/2022] [Accepted: 11/16/2022] [Indexed: 05/07/2023]
Abstract
PURPOSE To calculate the costs of treatment for diabetic macular edema with bevacizumab-first (step therapy) compared with aflibercept monotherapy. DESIGN Cost analysis of the treatment arms based on a published study. SUBJECTS None. METHODS Published results from the Diabetic Retinopathy Clinical Research Network protocol AC were used to assess costs. Data incorporated in the usage and outcome model included the frequency of injections, medication type, visits, and imaging. Costs were modeled based on the 2022 Medicare reimbursement data for both facility (hospital-based) and nonfacility settings in Miami. Outcomes were similar in protocol AC so were not differentially studied. Results were extrapolated so as to estimate lifetime (17 years for the age of the cohort). MAIN OUTCOME MEASURES Cost of treatment options. RESULTS Over the 2 years reported in the protocol AC, the cost required to treat in the facility (nonfacility setting) was $42 000 ($32 000) in the aflibercept monotherapy group and $29 000 ($22 000) in the bevacizumab-first group. Extrapolated modeled lifetime costs were $158 000 ($136 000) and $125 000 ($103 000), respectively. The total cost with bevacizumab-first was 33% lower at year 2 and 21% lower at year 17 compared with aflibercept monotherapy. Savings per year for the 2 years results were $6500 ($5000) in the facility (nonfacility) setting. For the extrapolated 17 years model, annual savings were $1900 ($1900) in the facility (nonfacility) setting. The professional fees accounted for a minority of overall costs; in contrast, medication costs accounted for 82% of the total costs for the aflibercept monotherapy and 73% in the bevacizumab-first group at 2 years. Our model predicted an additional 15% lifetime cumulative savings if patients still not meeting the threshold criteria after switching to aflibercept were placed back on bevacizumab, and a similar degree of improvement if those on not meeting threshold criteria on aflibercept monotherapy were switched to bevacizumab. CONCLUSIONS Medication is the dominant driver of the total expenses associated with the treatment of diabetic macular edema. Although cost savings are realized with bevacizumab-first step therapy, the magnitude was not as much as might be intuited, probably because of the high (70%) incidence of patients switching to aflibercept within protocol AC.

Abstract
Retinal displacement following the repair of rhegmatogenous retinal detachment (RRD) has been reported in recent studies. It was described as vertical movement of the retinal relative to its original location, as evidenced by retinal vessel printing on fundus autofluorescence imaging. This review reports the current literature on retinal displacement. We conducted an English literature search using Medline, PubMed, Embase, and Web of Science. We have reviewed 22 articles describing the diagnosis, frequency, and possible risk factors for retinal displacement. The reported rate of retinal displacement ranged from 6.4% to 62.8%, and the possible risk factors included the detachment-to-repair time, location and extent of RRD, macula-off RD, presence of subretinal fluid, use of perfluorocarbon, use of tamponade, postoperative facedown positioning, type of RRD repair, and presence of proliferative vitreoretinopathy, especially high grade. This review increases awareness of retinal displacement and its associated visual effects.

Abstract
PURPOSE To describe the clinical features and visual outcomes of eyes with conjunctival haptic erosion after sutureless intrascleral (SIS) fixated intraocular lens (IOL) placement. DESIGN Retrospective case series. SUBJECTS Patients experiencing haptic erosion after SIS fixation between January 1, 2013, and March 1, 2022. METHODS A multicenter, multisurgeon, retrospective review. MAIN OUTCOME MEASURES Clinical features, visual outcomes, and treatment options following haptic erosions after SIS fixation. RESULTS Nineteen eyes with haptic erosion were identified. The mean age at initial SIS fixation was 64 ± 12 years (range, 38-81 years). There were 5 (26%) eyes with a history of conjunctiva involving ocular surgery, including scleral buckle surgery and tube shunt surgery. Trocar-assisted fixation was performed in 15 (79%) eyes, whereas needle fixation was used in 4 (21%) eyes. Eighteen (95%) sets of haptics were flanged with a low temperature cautery. Seventeen (90%) sets of haptics were externalized superiorly and inferiorly, and 2 (10%) sets of haptics were externalized nasally and temporally. Haptics were covered by conjunctiva in 14 (74%) eyes and by scleral flap in 5 (26%) eyes. All patients experienced a single haptic erosion, of which 8 (43%) were located superiorly, 9 (47%) inferiorly, and 2 (10%) temporally. The mean interval between the initial SIS fixation and haptic erosion was 278 ± 437 days. After correction of the erosion, 18 (95%) eyes had a stable IOL at the last follow-up, with no recurrence of haptic erosion. In this series, there were no cases of endophthalmitis. CONCLUSIONS Haptic erosion is a notable complication after SIS fixated IOL surgery but may be repaired with favorable visual outcomes. Careful evaluation of the conjunctiva should be considered before the surgery. FINANCIAL DISCLOSURE(S) Proprietary or commercial disclosure may be found after the references.

Abstract
Purpose To evaluate the outcomes and complications in patients with retained lens fragments (RLF) after cataract surgery, comparing those who received pars plana vitrectomy (PPV) on the same day, within 1 week, or later than 1 week after cataract surgery. Patients and Methods Retrospective case series of all patients who underwent PPV for RLF at Bascom Palmer Eye Institute between January 1, 2012 and September 30, 2020. Individuals with less than 3 months of follow-up, chronic uveitis, congenital cataract, previtrectomy retinal detachment (RD), and severe trauma were excluded. All analyses for categorical and binary variables used chi-squared tests. Analyses for continuous variables were performed using multivariate analyses of covariance, adjusting for differences in baseline visual acuity before cataract surgery. Results The study included 246 eyes of 246 patients. The timing distribution included the following: 140 (57%) eyes underwent same-day PPV, 33 (13%) eyes underwent same-week PPV, and 73 (30%) eyes underwent PPV after 1 week (up to 90 days). When all eyes were included in analysis, there were no statistically significant differences in mean best-corrected visual acuity (BCVA) between groups at last follow-up examination (P = 0.07). When only eyes without known pre-existing ocular disease (N = 157) were included in analysis, there were no differences in mean BCVA between groups at all postoperative timepoints (P > 0.05). The rate of RD did not differ between groups when eyes with and without pre-existing ocular disease were analyzed (P > 0.05). Conclusion In the current study, there were no statistically significant differences in postoperative BCVA or rates of RD at last follow-up examination in eyes undergoing PPV for RLF on the same day, within 1 week, or later than 1 week after cataract surgery.

Abstract
Objective To review clinical outcomes of patients with proliferative diabetic retinopathy (PDR) and vitreous hemorrhage (VH) who underwent pars plana vitrectomy (PPV) with endolaser panretinal photocoagulation (PRP) without retinal detachment (RD) repair. Methods Retrospective chart review of the rate of postoperative clinical findings and visual acuity in patients with PDR from May 2014 to August 2021. Results Pars plana vitrectomy with endolaser PRP was performed in 81 eyes of 81 patients (mean age of 62.1 ± 10.5 years). At a median follow-up of 18 months, mean Snellen best-corrected visual acuity (BCVA) significantly improved from 20/774 preoperatively to 20/53 at last follow-up (P < 0.001). Postoperative complications and clinical findings included VH (12.3%), diabetic macular edema (DME) (12.3%), ocular hypertension (8.6%), RD (4.9%), and need for additional PPV (6.2%). Eyes with PRP performed within 6 months before surgery had a lower frequency of developing postoperative VH (5.3%) compared to eyes that received PRP more than 6 months before surgery (27.3%, P = 0.04). Eyes that received preoperative anti-vascular endothelial growth factor (VEGF) treatment (2.0%) had a lower frequency of postoperative VH compared to eyes that did not receive anti-VEGF treatment (14.3%, P = 0.04). Eyes that received intraoperative sub-tenon triamcinolone acetonide developed postoperative DME (4.0%) less frequently than eyes that did not receive sub-tenon triamcinolone acetonide (26.7%, P = 0.04). Conclusion In patients with PDR and VH, PPV with PRP yielded significant improvements in visual acuity and resulted in overall low rates of recurrent postoperative VH. Preoperative anti-VEGF and PRP laser treatment were associated with lower rates of postoperative VH. Furthermore, intraoperative use of sub-tenon triamcinolone acetonide was associated with a lower rate of postoperative DME. Pars plana vitrectomy with endolaser PRP in conjunction with the aforementioned pre- and intraoperative therapies is an effective treatment for patients with PDR and VH.

Cost analysis of childhood glaucoma surgeries using the US Medicaire allowable costs. Int J Ophthalmol 2023; 16:700-704. [PMID: 37206176 PMCID: PMC10172091 DOI: 10.18240/ijo.2023.05.05] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2022] [Accepted: 03/30/2023] [Indexed: 05/21/2023] Open
Abstract
AIM To analyze and calculate the relative cost of various childhood glaucoma surgical interventions per mm Hg intraocular pressure (IOP) reduction ($/mm Hg). METHODS Representative index studies were reviewed to quantitate the reduction of mean IOP and glaucoma medications for each surgical intervention in childhood glaucoma. A US perspective was adopted, using Medicare allowable costs to calculate cost/mm Hg IOP reduction ($/mm Hg) at 1y postoperatively. RESULTS At 1y postoperatively, the cost/mm Hg IOP reduction was $226/mm Hg for microcatheter-assisted circumferential trabeculotomy, $284/mm Hg for cyclophotocoagulation, $288/mm Hg for conventional ab-externo trabeculotomy, $338/mm Hg for Ahmed glaucoma valve, $350/mm Hg for Baerveldt glaucoma implant, $351/mm Hg for goniotomy, and $400/mm Hg for trabeculectomy. CONCLUSION Microcatheter-assisted circumferential trabeculotomy is the most cost-efficient surgical method to lower IOP in childhood glaucoma, while trabeculectomy is the least cost-efficient surgical method.

Intraocular Lens Exchange: Indications, Comparative Outcomes by Technique, and Complications. Clin Ophthalmol 2023; 17:941-951. [PMID: 36993987 PMCID: PMC10041992 DOI: 10.2147/opth.s399857] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/23/2022] [Accepted: 02/24/2023] [Indexed: 03/31/2023] Open
Abstract
Purpose To describe the indications, outcomes, and complications associated with intraocular lens (IOL) exchange. Patients and Methods To determine the relative frequency of postoperative complications between techniques for all patients undergoing IOL exchange from May 1, 2014 through August 31, 2020. Results IOL exchange was performed in 511 eyes of 489 patients (59.7% men; mean age: 67.0 ± 13.9 years, median time from cataract procedure to IOL exchange: 47.5 months). Mean uncorrected visual acuity significantly improved from 20/192 Snellen equivalent (logMAR 0.981) preoperatively to 20/61 (logMAR 0.487) at last follow-up (P < 0.001). Overall, 384 eyes (78.7%) met their desired refractive outcome within ±1.0 diopter (D). The most frequent complication was cystoid macular edema (CME) (n=39, 7.6%). Iris-sutured technique was associated with significantly greater frequency of subsequent IOL dislocation (10.3%) than 4-point scleral sutured (0%, P = 0.002), anterior chamber IOL (ACIOL, 1.5%, P = 0.01), and 2-point scleral sutured (0%, P = 0.03) techniques. Yamane scleral-fixation technique was associated with significantly greater frequency of developing IOL tilt (11.8%) than ACIOL (0%, P = 0.002), 4-point scleral sutured (1.1%, P = 0.01), 2-point scleral sutured (0%, P = 0.04), and iris-sutured (0%, P = 0.04) techniques. Conclusion IOL exchange significantly improved uncorrected visual acuity and more than three-quarters of eyes met the refractive goal. Certain techniques were associated with complications, including subsequent dislocation associated with iris-sutured technique and IOL tilt associated with Yamane scleral-fixation technique. This information may help guide surgeons in deciding between procedural techniques for individual patients during IOL exchange preoperative planning.

Outcomes in Patients with Suprachoroidal Hemorrhage After Anterior Segment Surgery. Clin Ophthalmol 2022; 16:4199-4205. [PMID: 36544898 PMCID: PMC9762989 DOI: 10.2147/opth.s379557] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2022] [Accepted: 11/07/2022] [Indexed: 12/23/2022] Open
Abstract
Objective The purpose of the current study is to report outcomes of suprachoroidal hemorrhage (SCH) after anterior segment surgery at a single institution, and to identify clinical features associated with visual prognosis. Methods and Analysis Retrospective consecutive case series of patients with SCH occurring after anterior segment surgery. Results The study includes 112 eyes of 112 patients between 2014 and 2020. There were 76 cases of non-appositional SCH versus 36 cases of appositional SCH. The mean presenting visual acuity for patients with non-appositional versus appositional SCH was 2.03 logMAR (SD 0.78) versus 2.39 logMAR (SD 0.43), respectively. Visual acuity outcomes generally remained poor at last follow-up: 64 (58%) patients had a visual acuity (VA) of ≤ 20/200, including 19 (17%) with light perception (LP), and 11 (10%) with no light perception (NLP). Regarding management of non-appositional versus appositional SCH, observation was selected in 46 (61%) vs 12 (33%), delayed drainage in 14 (18%) vs 15 (42%), delayed pars plana vitrectomy in 16 (21%) vs 13 (36%), and VA at last follow-up was 1.2 versus 1.86 logMAR (p=0.002). In patients that were observed, both appositional SCH (p=0.01) and duration of apposition (p=0.04) were correlated with worse outcome. Conclusion Appositional SCH was associated with poorer visual outcomes compared to non-appositional SCH. Observation remains a reasonable management strategy for non-appositional SCH.

Abstract
BACKGROUND AND OBJECTIVE Determine clinical characteristics and long-term outcomes of fellow eyes for patients with prior repair of rhegmatogenous retinal detachments due to a giant retinal tear (GRT). STUDY DESIGN Retrospective case series of patients who underwent vitreoretinal surgery between January 2005 and August 2017 for GRT at the Bascom Palmer Eye Institute with a minimum of one year of follow-up information. Patients with a traumatic or post-vitrectomy GRT were excluded. MAIN OUTCOME MEASURES Visual acuity and rate of retinal events in fellow eyes. RESULTS The study group included 51 patients; 40 others were excluded due to having less than one year of follow-up (n = 27), a history of inciting trauma (n = 11), or a GRT occurring post-vitrectomy (n = 2). The mean age was 49.9 years (range 14 to 81) and mean follow-up duration was 6.9 years (range 1 to 16). During the follow-up interval, prophylactic laser retinopexy was performed in 5 fellow eyes for retinal breaks (9.8%) and in one fellow eye with a progressing retinoschisis cavity (2.0%). One patient had a previous history of a retinal break in the fellow eye. Vitreoretinal surgery was performed in 6 (11.8%) fellow eyes for rhegmatogenous retinal detachments, of which one was caused by a GRT. Three patients (5.9%) already had a retinal detachment repair in the fellow eye prior to presentation and one patient presented with bilateral giant retinal tear associated retinal detachments (GRT-RDs) at the initial visit. Overall, there was a retinal event in 33.3% of fellow eyes. Myopia was the most commonly documented associated factor (31%), followed by lattice degeneration (22%), and known or suspected inherited vitreoretinopathy (4%). CONCLUSIONS Retinal tears and/or detachments were encountered relatively frequently in the fellow eye of patients with a history of GRT-RD during follow-up, but the rate of GRTs in the fellow eye (4%) was below what has been generally reported in the literature. Regular dilated fundus exams are warranted for patients with a history of GRT. [Ophthalmic Surg Lasers Imaging Retina 2022;53:619-625.].

Abstract
PURPOSE To evaluate acute-onset postoperative endophthalmitis following cataract surgery and to compare rates between resident and attending physician-performed cohorts. SETTING Bascom Palmer Eye Institute, Miami, Florida. DESIGN Retrospective chart review. METHODS Records of patients diagnosed with endophthalmitis within 6 weeks of surgery performed by attending and resident physicians between January 1, 2015, and December 31, 2020, were reviewed. Total cataract volume was obtained from institutional records, and resident case totals were obtained from case logs. Endophthalmitis cases were obtained from billing records and confirmed with chart review. RESULTS There were 22 cases of endophthalmitis among 32 505 cases (0.068%). Endophthalmitis occurred in 6 of 6447 (0.093%) resident cases and 16 of 26 058 (0.061%) attending cases ( P = .55). The most common bacterial isolates were coagulase-negative Staphylococcus (8/22, 36.3%) and Streptococcus species (3/22, 13.6%), with negative cultures in 10 (10/22, 45.5%). Initial treatment with vitreous tap and injection of intravitreal antibiotics was performed in 21 eyes (21/22, 95.4%) and vitrectomy with intravitreal antibiotic injection in one (1/22, 4.5%). Vitrectomy was performed secondarily in 9 patients (9/22, 40.9%). Corrected distance visual acuity (CDVA) at last follow-up was ≥20/40 in 13 eyes (13/22, 59%) and ≤hand motions in 3 eyes (3/22, 13.6%). CDVA (logMAR mean ± SD) was 1.22 ± 1.16 in resident and 0.49 ± 0.79 in attending cases ( P = .11). CONCLUSIONS In the current study, acute-onset postoperative endophthalmitis developed infrequently following cataract surgery. The rates and visual outcomes of endophthalmitis were similar in resident and attending cases.

Mechanical Property Comparison of 23-, 25-, and 27-Gauge Vitrectors across Vitrectomy Systems. Ophthalmol Retina 2022; 6:1001-1008. [PMID: 35569764 PMCID: PMC9637701 DOI: 10.1016/j.oret.2022.05.004] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2022] [Revised: 04/18/2022] [Accepted: 05/09/2022] [Indexed: 11/22/2022]
Abstract
OBJECTIVE To investigate the mechanical properties of 23-, 25-, and 27-gauge vitrectomy vitrectors across 3 different vitrectomy systems to inform surgical techniques. DESIGN An experimental study that did not involve any human subjects. METHODS Nine vitrectors (3 each of 23-, 25-, and 27 gauge) from Alcon, Dutch Ophthalmic Research Center (DORC), and Bausch & Lomb (B/L) were measured. Measurements were performed using electroforce displacement at the tip and 15 mm from the tip. Five measurements were performed at each location, and fully elastic deformation was ensured. MAIN OUTCOME MEASURES The main parameter being measured was the force in grams (gf) necessary to deflect the vitrectors vertically downward by 1 mm, either at the tip of the vitrector or 15 mm from the tip. RESULTS A total of 90 measurements were performed. Across brands, B/L demonstrated the least stiffness at both the tip and at the 15-mm point for 23-gauge (8.0±0.3gf, 67.3±1.0gf), 25-gauge (6.8±0.3gf, 60.5±0.4gf), and 27-gauge (3.3±0.1gf, 33.9±0.5gf) vitrectors. Although there was only a small decrease in the stiffness in the 25-gauge vitrector compared with the 23-gauge vitrector at the 15-mm point, this difference was statistically significant for Alcon (P < 0.001), DORC (P < 0.001), and B/L (P < 0.001). CONCLUSIONS Based on this study, 25-gauge vitrectors, although larger than the 27-gauge vitrectors and less stiff than the 23-gauge vitrectors, may offer favorable compromise between stiffness and gauge size. However, surgeon experience, preference, and the type of surgery being performed should be paramount when making the final vitrector selection. Knowledge of these mechanical properties may aid surgeons in choosing between gauge size and vitrectomy system to optimize their comfort and efficiency.

Abstract
IMPORTANCE Traumatic eye injury is one of the leading causes of visual impairment in the United States, but there is limited information available in the literature about ocular trauma related to sports. OBJECTIVE To evaluate the primary ocular diagnosis, type of sport, seasonal prevalence, and injury severity following ocular sports-related trauma. DESIGN Cross-sectional study. SETTING United States (US) hospital emergency departments (ED). PARTICIPANTS Patients with sports-related ocular injuries in the National Electronic Injury Surveillance System All Injury Program (NEISS-AIP) database from January 1, 2010 to December 31, 2019. MAIN OUTCOME AND MEASURE To identify and compare the type of sport, primary diagnosis of ocular injury, and injury severity. RESULTS For 4,671 sports-related ocular injuries identified, the mean age of injury was 19.4±15.2 years (median: 15.0 years, 79% male). The largest proportion of injuries occurred in the 12-17 years of age cohort (38.6%), occurring during summer months (P< .001). The most common sports associated with eye injury were basketball (37.8%), baseball (13.8%),, and football (12.3%). There were 3,214 injuries (68.8%) deemed 'minor' anterior segment injuries, 359 injuries (7.7%) deemed 'major' anterior segment injuries, 31 injuries (0.7%) deemed 'minor' posterior segment injuries, 77 injuries (1.7%) deemed 'major' posterior segment injuries, and 990 injuries (21.2%) of unknown severity. Basketball-related ocular trauma had a greater frequency of corneal/scleral abrasions than baseball (P < .001), soccer (P < .001), tennis (P = .03), softball (P = .001), and paintball (P = .02). Baseball-related ocular trauma had a greater frequency of contusions than basketball (P < .001), football (P < .001), soccer (P < .001), volleyball (P< .001). Paintball and soccer were more associated with 'major' anterior and posterior ocular injuries than basketball (P < .001, for both). CONCLUSION AND RELEVANCE Sports-related trauma remains a highly prevalent cause of eye-related visits to the emergency room, particularly in young male adolescents in the spring and summertime. While most diagnoses were deemed 'minor' injuries with basketball associated with corneal/scleral abrasions and baseball with contusions, paintball, and soccer were more significantly associated with 'major' anterior and posterior ocular injuries.

Abstract
PURPOSE To evaluate the incidence and degree of retinal displacement following scleral buckling surgery for macula-involving rhegmatogenous retinal detachment. METHODS Retrospective interventional case series comprised of patients treated with primary scleral buckling procedure without gas tamponade for macula-involving rhegmatogenous retinal detachment and imaged postoperatively with fundus autofluorescence imaging between June 1, 2016 and July 25, 2021. Clinical notes, operative reports, fundus autofluorescence photographs, and optical coherence tomography images were reviewed. The presence and degree of retinal displacement were recorded. RESULTS Twelve eyes of 11 patients were included. One (8%) eye with an epiretinal membrane demonstrated 0.1 mm of retinal displacement along the superior arcade and in the superotemporal periphery. The remainder of eyes (92%) did not show any identifiable signs of retinal displacement. CONCLUSION Retinal displacement does not seem to be a frequent complication of primary scleral buckling surgery for macula-involving rhegmatogenous retinal detachment.

Abstract
PURPOSE Venous thromboembolic complications have been reported in association with coronavirus disease 2019 (COVID-19) infection. We raised awareness regarding a potential temporal association between COVID-19 infection and retinal vein occlusion (RVO). DESIGN Multicenter, retrospective, nonconsecutive case series. SUBJECTS Patients presenting with hemi-RVO (HRVO) or central RVO (CRVO) between March 2020 and March 2021, with confirmed COVID-19 infection, were included. The exclusion criteria were as follows: age >50 years, hypertension, diabetes, glaucoma, obesity, underlying hypercoagulable states, and those requiring intubation during hospitalization. METHODS This was a multicenter, retrospective, nonconsecutive case series including patients presenting with hemi-RVO (HRVO) or central RVO (CRVO) between March 2020 and March 2021, with confirmed COVID-19 infection. The exclusion criteria were as follows: age >50 years, hypertension, diabetes, glaucoma, obesity, underlying hypercoagulable states, and those requiring intubation during hospitalization. MAIN OUTCOME MEASURES Ophthalmic findings, including presenting and final visual acuity (VA), imaging findings, and clinical course. RESULTS Twelve eyes of 12 patients with CRVO (9 of 12) or HRVO (3 of 12) after COVID-19 infection were included. The median age was 32 years (range, 18-50 years). Three patients were hospitalized, but none were intubated. The median time from COVID-19 diagnosis to ophthalmic symptoms was 6.9 weeks. The presenting VA ranged from 20/20 to counting fingers, with over half (7 of 12) having a VA of ≥20/40. OCT revealed macular edema in 42% of the eyes; of these, 80% (4 of 5) were treated with anti-VEGF injections. Ninety-two percent (11 of 12) had partial or complete resolution of ocular findings at final follow-up. Four eyes (33%) had retinal thinning, as determined using OCT, by the end of the study interval. The final VA ranged from 20/20 to 20/60, with 11 of the 12 (92%) eyes achieving a VA of ≥20/40 at a median final follow-up period of 13 weeks (range, 4-52 weeks). CONCLUSIONS Although we acknowledge the high seroprevalence of COVID-19 and that a causal relationship cannot be established, we reported this series to raise awareness regarding the potential risk of retinal vascular events due to a heightened thromboinflammatory state associated with COVID-19 infection.

Abstract
Bilateral diffuse uveal melanocytic proliferation (BDUMP) is a rare paraneoplastic syndrome. Diagnosis can be difficult and treatment guidelines are ill-defined. A 73-year-old man with poorly differentiated high grade urothelial carcinoma of the ureter metastatic to the liver, lungs, lymph nodes, and pelvis treated with chemotherapy and immunotherapy reported gradual vision loss. Optical coherence tomography (OCT) demonstrated intraretinal and subretinal fluid with hyperreflective subretinal deposits and focal, deeply pigmented choroidal lesions. Irregular hyperpigmentation of the retinal pigment epithelium (RPE) with a "leopard spot" pattern on fundus autofluorescence (FAF) supported the diagnosis of BDUMP. Multiple plasmapheresis sessions did not result in sustained clinical improvement. [Ophthalmic Surg Lasers Imaging Retina 2022;53(6): 350-353.].

Abstract
OBJECTIVE To review the clinical course and outcomes of patients with idiopathic vitreomacular traction (VMT) managed initially by observation. DESIGN Retrospective chart review including patients with idiopathic VMT based on clinical symptoms and findings on optical coherence tomography (OCT) between January 1, 2015 and February 15, 2021. SUBJECTS The study included 436 eyes of 317 patients with a mean age of 72.2 years ± 8.9 at initial visit and mean follow-up time of 34 months ± 19.2. METHODS VMT severity grade was ascribed to each patient using previously published grading criteria. Grade 1 denoted incomplete cortical vitreous separation with attachment at the fovea and visible distortion of the foveal surface, grade 2 included intraretinal cysts or clefts along with grade 1 findings, and grade 3 included sub-foveal fluid along with grade 2 traits. MAIN OUTCOME MEASURES The rate of spontaneous release, grade at baseline compared to grade at final follow-up, and outcomes of interventions if performed. RESULTS At baseline, mean best corrected visual acuity (BCVA) was 20/40. Baseline OCT demonstrated grade 1 VMT in 212 eyes (48.6%), grade 2 VMT in 172 eyes (39.4%), and grade 3 VMT in 52 eyes (11.9%). Among initially grade 1 eyes, 25.0% had spontaneous release of VMT (median: 290.0 days, mean: 404.5 days ± 323.9), 50.9% remained stable, and 10.4% worsened. Among initially grade 2 eyes, 14.5% had spontaneous release of VMT (median: 570.0 days, mean: 692.9 days ± 477.5), 55.2% remained stable, 4.7% improved, and 2.3% worsened. Among initially grade 3 eyes, 5.8% had spontaneous release of VMT (median: 790.0 days, mean: 839.3 days ± 246.7), 28.8% remained stable, and 5.8% improved. Of the 436 eyes, macular hole development occurred in 42 eyes (9.6%). PPV was performed in 94 of 436 eyes (21.6%) with mean BCVA prior to PPV of 20/78 and final follow-up BCVA of 20/55. CONCLUSION This study demonstrates the generally stable clinical course of VMT when managed initially by observation. Stable VMT grade was the most frequent outcome, and grade 1 VMT eyes were more likely to undergo spontaneous release compared to grades 2 and 3 eyes.

[PMID: 33780301 PMCID: PMC8478971 DOI: 10.1080/08820538.2021.1906918] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/15/2021] [Accepted: 03/15/2021] [Indexed: 01/04/2023]
Abstract
PURPOSE To describe the relationship between the number of Federal Drug Administration (FDA)-approved manufacturers and the price change of generic and branded topical eye drops. METHODS Retrospective analysis of topical eye drop medications with formulations listed in the FDA Orange Book and the National Average Drug Acquisition Cost database from 2013 to 2017. RESULTS The most frequently prescribed generic topical drugs were glaucoma medications (34%), antimicrobials (32%), anti-inflammatories (24%), mydriatics (5%), and anesthetics (5%). The most frequently prescribed branded topical drugs were anti-inflammatories (45%), glaucoma medications (32%), antimicrobials (21%) and dry eye medications (3%). From 2013 to 2017, generic eye drops had a median price decrease of 20% (IQR 32%) while branded eye drops had a median price increase of 44% (IQR 28%) (P < .001). A significant inverse association was identified between the price change of generic eye drops and the total number of all manufacturers (r = -.41, P = .010), generic drug manufacturers (r = -.32, P = .0496), and alternative branded drug manufacturers (r = -.57, P = .002). There was no significant association between the price change of branded eye drops and number of manufacturers. Glaucoma (r = -.58, P = .039) and anti-inflammatory (r = -.69, P = .047) eye drops also had significant inverse associations with the number of generic manufacturers. CONCLUSION From 2013 to 2017, the price of generic eye drops decreased whereas the price of branded eye drops increased. Market competition was significantly inversely associated with price changes of generic eye drops but not branded eye drops.

Content, Readability, and Accountability of Freely Available Online Information for Patients Regarding Epiretinal Membranes. Semin Ophthalmol 2022; 37:67-70.

Abstract
PURPOSE To assess content, readability, and accountability of online information for patients regarding epiretinal membranes (ERMs). METHODS Cross-sectional study evaluating nine major medical websites on ERMs. Fifteen questions assessed patient-relevant content. Four indices estimated U.S. grade literacy level of the text. JAMA benchmarks (authorship, attribution, disclosure, currency) evaluated website accountability. RESULTS Average content score was 36.78 (SD 13.91, 95% CI ±0.64) from a possible maximum of 60, with significant variability between websites (H = 22.68, p=0.004). Mean reading grade level was 12.29 (SD 2.30, 95% CI ±1.50). No website achieved all JAMA benchmarks; only one website fulfilled three of the four. Content score did not correlate with Google rank (order of listed websites, r = -0.23, p=0.55) or JAMA benchmarks (r = 0.19, p=0.62) but significantly correlated with mean reading grade (r = 0.67, p=0.05). CONCLUSION Online information regarding ERMs varies significantly, may not adequately answer common patient questions, and is written at too complex a literacy level for the average patient.
