ABSTRACT

BACKGROUND/PURPOSE: To determine and compare the efficacy of a surgical internal limiting membrane (ILM) flap technique with the traditional ILM peel on long-term visual and anatomical outcomes for large (>400 µm) full-thickness macular holes. METHODS: From October 2016 to July 2022, patients undergoing initial full-thickness macular hole repair with the ILM flap or ILM peel technique were reviewed. Final outcomes were recorded and based on size in microns: 401 to 800, 801 to 1,200, and >1,200. RESULTS: Patients treated with ILM flap (n = 52, 94.2% closure rate) or ILM peel (n = 407, 93.6% closure rate) were followed with a mean follow-up time of 15.0 ± 10.2 and 20.0 ± 13.4 months, respectively. Success rates for ILM flaps and ILM peels were compared for full-thickness macular holes of 401 to 800 (100%, 95.8%, P = 0.39), 801 to 1,200 (95%, 93%, P = 0.74), and >1,200 (86.7%, 86.7%, P = 1.0) µm. Mean best-recorded logarithm of the minimal angle of resolution visual acuity for ILM flaps and ILM peels, respectively, was 1.02 ± 0.46 and 0.87 ± 0.47 preoperatively, with follow-up acuity of 0.48 ± 0.32 (P < 0.03) and 0.39 ± 0.42 (P < 0.01) at Year 3. CONCLUSION: Both techniques provide a similar anatomical closure rate and functional improvement in vision. Comparisons should be cautiously made based on difference in preoperative hole size.

ABSTRACT

PURPOSE: To evaluate the association of posterior vitreous opacities (PVOs) on optical coherence tomography with retinal tears identified on examination in patients with acute, symptomatic posterior vitreous detachment (PVD). METHODS: Data were retrospectively collected from the medical records of 388 patients with acute, symptomatic PVD between January 1, 2021, and June 30, 2021. Included patients had received a primary diagnosis of PVD and presented with flashes and/or floaters. Optical coherence tomography scans were reviewed by two separate readers for the presence of PVOs. The primary outcome was the presence of retinal tear on fundus photograph and on examination. RESULTS: Of 388 patients who presented with acute PVD symptoms, 90 (23.2%) were found to have a retinal tear on dilated fundus examination. Among these patients, 78 (86.7%) were found to have PVOs on optical coherence tomography. Statistical analysis demonstrated a significant relationship between the presence of PVOs and retinal tear ( P < 0.01). The sensitivity and specificity of this finding was 86.7% and 72.5%, respectively. Further analysis included area under the curve from receiver operating characteristic curve which was found to be 0.80. CONCLUSION: The presence of PVOs on optical coherence tomography is suggestive of a retinal tear in patients with acute, symptomatic PVD.

ABSTRACT

People living with HIV (PLWH) have increased risk of osteoporosis and fractures. We assessed the proximal femur of PLWH and age-matched seronegative controls using quantitative computed tomography and magnetic resonance imaging. Results suggest that the trabecular compartment is compromised at fracture-prone regions in the proximal femur of PLWH. INTRODUCTION: People living with HIV (PLWH) have increased risk of osteoporosis and fractures. However, studies assessing the main determinants of bone strength in the proximal femur exclude this vulnerable population. We assessed the proximal femur of 40 PLWH and 26 age-matched seronegative controls using quantitative computed tomography and magnetic resonance imaging. METHODS: We examined cortical volumetric bone mineral density (Ct.vBMD), trabecular vBMD (Tb.vBMD), cortical thickness (Ct.Th), bone marrow adiposity (BMA), and trabecular number, separation, and bone volume fraction. Parametric comparisons between the two groups were made for the femoral head, femoral neck, trochanter, and total hip using linear regression adjusting for several covariates, including metrics of body composition. In addition, we investigated the associations of BMA with Tb.vBMD and trabecular microarchitecture with Spearman's rank partial correlations. RESULTS: PLWH had lower Tb.vBMD and deteriorated trabecular microarchitecture in the femoral neck, trochanter and total hip, and elevated BMA in the femoral head, femoral neck, and total hip. Ct.vBMD and Ct.Th were not significantly different between the two groups. BMA was significantly associated with lower Tb.vBMD and deteriorated trabecular microarchitecture in both groups albeit at different femoral regions. CONCLUSIONS: Our findings suggest that the trabecular, and not the cortical, compartment is compromised in the proximal femur of PLWH. The observed impairments in fracture-prone regions in PLWH indicate lower femoral strength and suggest higher fracture risk. The inverse associations of BMA with trabecular bone density and microarchitecture quality agree with findings at other anatomic sites and in other populations, suggesting that excess BMA possibly due to a switch from the osteoblast to the adipocyte lineage may be implicated in the pathogenesis of bone fragility at the femur in PLWH.

ABSTRACT

PURPOSE: To compare the visual outcomes and complication rates of sutureless cannula-based intraocular lens scleral (SCILS) fixation performed with 25-gauge (25 G) versus 27-gauge (27 G) instrumentation. METHODS: A retrospective chart review of consecutive cases of eyes without capsular support that underwent SCILS fixation of a three-piece intraocular lens. Sutureless cannula-based intraocular lens scleral fixation was performed by transconjunctival use of either 25-G or 27-G trocar cannulas. During postoperative follow-up evaluations, visual acuity and intraocular pressure were measured, and slit-lamp and indirect ophthalmoscopy examinations were performed to assess for development of known complications. RESULTS: A total of 69 eyes underwent 25 G (27 eyes) or 27 G (42 eyes) SCILS fixation. The mean preoperative logarithm of the minimum angle of resolution visual acuity trended toward improvement from 0.95 ± 0.68 (20/178 Snellen equivalent) to 0.67 ± 0.64 (20/94 Snellen equivalent) for 25 G group at 1 year. Similar trend toward visual acuity improvement was seen in 27 G group with a mean preoperative logarithm of the minimum angle of resolution visual acuity of 1.43 ± 0.94 (20/538 Snellen equivalent) improving to 0.86 ± 1.00 (20/145 Snellen equivalent) at 1 year. Statistically significant improvement was seen as early as postoperative week one for 27 G group (P < 0.01), whereas statistically significant worsening was noted at the same time in 25 G group (P = 0.01). There was a statistically significant reduction in intraocular lens displacement (P = 0.01) and need for reoperation (P = 0.01) in 27 G group. CONCLUSION: Compared with 25 G SCILS fixation, eyes managed with 27 G SCILS fixation experienced more rapid visual acuity improvement. In addition, there was a lower rate of complications including intraocular lens displacement and need for reoperation.

ABSTRACT

OBJECTIVES: Elite controllers (ECs), viraemic controllers (VCs), and long-term nonprogressors (LTNPs) control HIV viral replication or maintain CD4 T-cell counts without antiretroviral therapy, but may have increased cardiovascular disease (CVD) risk compared to HIV-uninfected persons. We evaluated subclinical carotid and coronary atherosclerosis and inflammatory biomarker levels among HIV controllers, LTNPs and noncontrollers and HIV-uninfected individuals in the Multicenter AIDS Cohort Study (MACS) and the Women's Interagency HIV Study (WIHS). METHODS: We measured carotid plaque presence and common carotid artery intima-media thickness (IMT) in 1729 women and 1308 men, and the presence of coronary artery calcium and plaque in a subgroup of men. Associations between HIV control category and carotid and coronary plaque prevalences were assessed by multivariable regression analyses adjusting for demographics and CVD risk factors. Serum inflammatory biomarker concentrations [soluble CD163 (sCD163), soluble CD14 (sCD14), galectin-3 (Gal-3), galectin-3 binding protein (Gal-3BP) and interleukin (IL)-6] were measured and associations with HIV control category assessed. RESULTS: We included 135 HIV controllers (30 ECs) and 135 LTNPs in the study. Carotid plaque prevalence and carotid IMT were similar in HIV controllers, LTNPs and HIV-uninfected individuals. HIV controllers and LTNPs had lower prevalences of carotid plaque compared to viraemic HIV-infected individuals. The prevalence of coronary atherosclerosis was similar in HIV controllers/LTNPs compared to HIV-uninfected and viraemic HIV-infected men. Controllers and LTNPs had higher concentrations of sCD163 and sCD14 compared to HIV-uninfected persons. CONCLUSIONS: Subclinical CVD was similar in HIV controllers, LTNPs and HIV-uninfected individuals despite elevated levels of some inflammatory biomarkers. Future studies of HIV controllers and LTNPs are needed to characterize the risk of CVD among HIV-infected persons.

ABSTRACT

PURPOSE: To determine the efficacy of a novel application of a surgical internal limiting membrane flap technique that requires no additional surgical adjuvants in closure of large full-thickness macular holes (FTMHs). METHODS: The electronic medical records of patients (n = 8) with large (>400 µm) FTMHs repaired with the "Texas Taco" technique were retrospectively reviewed. RESULTS: Operated patients had a mean age of 63.8 ± 19.2 (range, 19-80) years. There were five (62.5%) phakic and three (37.5%) pseudophakic eyes preoperatively. Mean follow-up time was 9.1 ± 4.7 (1.5-14.5) months. Across all patients, mean FTMH diameter at the shortest and greatest widths were 529 ± 101 (404-661) and 1,189 ± 290 (829-1,656) µm, respectively. Mean best-corrected logarithm of the minimum angle of resolution visual acuity was 1.3 ± 0.23 preoperatively (approximately Snellen acuity 20/400) and 0.66 ± 0.40 postoperatively (approximately Snellen acuity 20/100) (P < 0.001). All FTMHs remained closed at all postoperative visits. CONCLUSION: The Texas Taco technique provided anatomical and functional improvement in challenging cases of large FTMHs without the need of additional surgical adjuvants.

ABSTRACT

PURPOSE: Evaluate the impact of time to surgery and other clinical factors on visual and anatomic outcomes following surgical repair of fovea-sparing rhegmatogenous retinal detachments (RRD). METHODS: Visual and anatomic outcomes were analyzed for their association with clinical factors, including lens status, preoperative visual acuity (VA), contralateral RRD, RRD symptom duration, time to surgery, single-operation anatomic success, number of quadrants involved, posterior RRD extent, RRD extent closest to the fovea, number of retinal breaks, quadrants with retinal breaks, and surgery performed Saturday or Sunday versus Monday-Friday. RESULTS: Medical records of 423 eyes with fovea-sparing RRD repaired with pneumatic retinopexy (PR), scleral buckle (SB), pars plana vitrectomy (PPV), and PPV with SB (PPV/SB) were included. Sixty-seven percent and 89% were operated within 24 and 72 h of RRD presentation, respectively. Single-operation anatomic success rates were 59%, 89%, 84%, and 92% for PR, SB, PPV, and PPV/SB interventions, respectively. Final anatomic success was 100%. Three clinical factors correlated with faster time to surgery: shorter symptom duration (p < 0.02), RRD superior location (p = 0.001), and posterior extension into the macula (p = 0.01). The time to surgery did not correlate with visual or anatomic outcomes. Two clinical factors positively correlated with postoperative vision: preoperative VA (r > 0.25, p < 0.04) and single-operation anatomic success (p < 0.04). Surgeries performed on Monday through Friday (n = 411) were associated with better anatomic outcomes compared with the limited number performed on Saturday or Sunday (n = 12) (p = 0.005), although a greater proportion of operated cases over the weekend were PR. CONCLUSIONS: In the context of the current series, time to surgery did not correlate with visual or anatomic outcomes following the surgical repair of fovea-sparing RRDs. Preoperative VA and single-operation anatomic success correlated with improved visual outcome.

ABSTRACT

PURPOSE: To evaluate the effect of targeted retinal photocoagulation (TRP) on visual and anatomic outcomes and treatment burden in eyes with diabetic macular edema (DME). DESIGN: Phase I/II prospective, randomized, controlled clinical trial. PARTICIPANTS: Forty eyes of 29 patients with center-involved macular edema secondary to diabetes mellitus. METHODS: Eyes with center-involved DME and Early Treatment Diabetic Retinopathy Study (ETDRS) best-corrected visual acuity (BCVA) between 20/32 and 20/320 (Snellen equivalent) were randomized 1:1 to monotherapy with 0.3 mg ranibizumab (Lucentis, Genentech, South San Francisco, CA) or combination therapy with 0.3 mg ranibizumab and TRP guided by widefield fluorescein angiography. All eyes received 4 monthly ranibizumab injections followed by monthly examinations and pro re nata (PRN) re-treatment through 36 months. Targeted retinal photocoagulation was administered outside the macula to areas of retinal capillary nonperfusion plus a 1-disc area margin in the combination therapy arm at week 1, with re-treatment at months 6, 18, and 25, if indicated. MAIN OUTCOME MEASURES: Mean change in ETDRS BCVA from baseline and number of intravitreal injections administered. RESULTS: At baseline, mean age was 55 years, mean BCVA was 20/63 (Snellen equivalent), and mean central retinal subfield thickness (CRT) was 530 µm. Thirty-four eyes (85%) completed month 36, at which point mean BCVA improved 13.9 and 8.2 letters (P = 0.20) and mean CRT improved 302 and 152 µm (P = 0.03) in the monotherapy and combination therapy arms, respectively. The mean number of injections administered through month 36 was 24.4 (range, 10-34) and 27.1 (range, 12-36), with 73% (362/496) and 80% (433/538) of PRN injections administered (P = 0.004) in the monotherapy and combination therapy arms, respectively. Goldmann visual field isopter III-4e area decreased by 2% and 18% in the monotherapy and combination therapy arms, respectively (P = 0.30). CONCLUSIONS: In this 3-year randomized trial of 40 eyes with DME, there was no evidence that combination therapy with ranibizumab and TRP improved visual outcomes or reduced treatment burden compared with ranibizumab alone.

ABSTRACT

PURPOSE: To describe the clinical and optical coherence tomography findings associated with the development of full-thickness macular holes after rhegmatogenous retinal detachment (RRD) repair. METHODS: Retrospective, interventional case series. All patients who developed full-thickness macular holes after successful RRD repair from 3 clinical practices were reviewed. All cases of combined/simultaneous full-thickness macular hole and RRD were excluded. The main outcome measure was the presence of an epiretinal membrane at time of diagnosis of macular hole. RESULTS: Twenty-five full-thickness macular holes were diagnosed after successful retinal detachment repair. Surgical approach to RRD repair included pneumatic retinopexy (6, 24%), scleral buckle alone (5, 20%), pars plana vitrectomy only (8, 32%), and combined scleral buckle and pars plana vitrectomy (6, 24%). The preceding RRD involved the macula in 19 patients (76%) before the formation of the macular hole. The median time to full-thickness macular hole diagnosis after RRD repair was 63 days (range, 4-4,080 days). An epiretinal membrane was present in all 25 (100%) macular holes. Two macular holes (8%) spontaneously closed, whereas the other 23 (92%) were successfully closed with a single surgical procedure. Mean visual acuity improved by approximately 5 lines to 20/72 (range, 20/20 to counting fingers at 1 foot) from 20/240 (range, 20/30 to hand motions) after macular hole repair (P < 0.0001). CONCLUSION: Full-thickness macular hole formation can occur after all types of RRD repair and is associated with an epiretinal membrane. The epiretinal membrane may play a role in the pathogenesis of secondary macular hole formation after RRD repair.

ABSTRACT

PURPOSE: To determine the rate of postintravitreal injection endophthalmitis and to assess microbiological features and outcomes with and without the use of peri-intravitreal injection topical ophthalmic antibiotics. METHODS: Consecutive series of endophthalmitis cases retrospectively identified after intravitreal injection at a multicenter, retina-only referral practice (Retina Consultants of Houston) from January 1, 2011 to December 31, 2014. Prophylactic peri-intravitreal injection topical antibiotics were routinely used during the initial 12-month period (January 1, 2011-December 31, 2011) and not used in the final 24-month period (January 1, 2013-December 31, 2014). Main outcome measures were incidence of endophthalmitis, microbiology results, treatment strategies, and visual outcomes. RESULTS: Of 90,339 intravitreal injections, 30 cases of endophthalmitis were identified (endophthalmitis rate = 0.033%; 95% confidence interval, 0.021-0.045%; or approximately 1 of 3,011 intravitreal injections). The most common organisms isolated were coagulase-negative staphylococci (n = 10, 33%), followed by Streptococcus mitis (n = 2, 7%). Fourteen cases (47%) were culture negative. Peri-intravitreal injection topical antibiotic prophylaxis did not decrease the rate of endophthalmitis (0.035% [95% CI, 0.007-0.064%] with antibiotic use versus 0.021% [95% CI, 0.008-0.033%] without antibiotic use; P = 0.261). CONCLUSION: The risk of endophthalmitis after intravitreal injection remains low, with coagulase-negative staphylococci and Streptococcus mitis the most common bacterial isolates identified. Prophylactic peri-intravitreal injection topical ophthalmic antibiotic use did not decrease the endophthalmitis rate.

ABSTRACT

OBJECTIVES: The aim of the study was to investigate the association of adiposity with longitudinal kidney function change in 544 HIV-infected persons in the Study of Fat Redistribution and Metabolic Change in HIV infection (FRAM) cohort over 5 years of follow-up. METHODS: The regional distribution of muscle and adipose tissue was quantified by whole-body magnetic resonance imaging (MRI), and total adiponectin and leptin levels were measured in serum. Kidney function was assessed using the estimated glomerular filtration rate from serum cystatin C (eGFRCys), obtained at baseline and follow-up. Rapid kidney function decline was defined as annual loss of eGFRCys ≥ 3 mL/min/1.73 m(2) , and incident chronic kidney disease (CKD) was defined as eGFRCys <60 mL/min/1.73 m(2) . Multivariate regression analysis was adjusted for age, race, gender, glucose, antihypertensive use, serum albumin, baseline and change in HIV viral load. RESULTS: At baseline, mean age was 43 years, mean eGFRCys was 86 mL/min/1.73 m(2) , and 21% of patients had albuminuria. The mean (± standard deviation) eGFRCys decline was -0.11 ± 4.87 mL/min/1.73 m(2) per year; 23% of participants had rapid kidney function decline, and 10% developed incident CKD. The lowest tertile of visceral adipose tissue and the highest tertile of adiponectin were both marginally associated with annual kidney function decline of -0.5 mL/min/1.73 m(2) each, but these associations were not statistically significant after adjustment. We found no statistically significant associations of MRI-measured regional adiposity or serum adipokines with rapid kidney function decline or incident CKD (all P-values>0.1 in adjusted models). CONCLUSIONS: Contrary to findings in the general population, adiposity did not have a substantial association with longitudinal change in kidney function among HIV-infected persons.

ABSTRACT

BACKGROUND: Serial wide-field fluorescein angiography was performed on eyes with preproliferative (ischemic) central retinal vein occlusion to evaluate retinal perfusion. METHODS: Serial wide-field fluorescein angiography was performed on 12 preproliferative central retinal vein occlusion eyes in the 3-year Rubeosis Anti-VEGF (RAVE) trial using the Staurenghi lens (Ocular Staurenghi 230SLO Retina Lens) with a scanning laser ophthalmoscope (Heidelberg HRA Spectralis). "Disk area" was defined anatomically for each eye. RESULTS: Mean total field of gradable retina was 290 disk areas (range, 178-452). All eyes demonstrated extensive areas of retinal nonperfusion; at baseline, mean area of retinal perfusion was 106 disk areas (range, 37-129), correlating with a mean of 46.5% perfused retinal area (range, 19.1-56.4%). The area of retinal nonperfusion increased in all eyes with a mean loss of approximately 8.1% of perfused retinal area per year (range, 4.3-12.4%), which corresponded to a mean 15-disk areas (range, 12-35) of retina evolving from perfused to nonperfused annually. The extent of baseline and final nonperfusion was not significantly different between eyes that developed neovascularization and eyes that did not. CONCLUSION: In this population of severe central retinal vein occlusion eyes, profound retinal nonperfusion was observed with wide-field fluorescein angiography at baseline and the extent of nonperfusion progressed while undergoing anti-vascular endothelial growth factor therapy.

ABSTRACT

PURPOSE: To analyze the efficacy and safety of ranibizumab in eyes with preproliferative (ischemic) central retinal vein occlusion. METHODS: In this prospective, phase I/II, open-label clinical trial, eyes at high risk of neovascular complications were identified; all eyes met ≥ 3 of 4 high-risk criteria: 1) the best-corrected visual acuity being ≤ 20/200, 2) loss of the 1-2e isopter on Goldmann visual field, 3) relative afferent pupillary defect being ≥ 0.9 log units, and 4) electroretinogram B-wave reduction to ≤ 60% of the corresponding A-wave. Monthly intravitreal ranibizumab treatment for 9 months, monthly monitoring for 3 months, and then monthly examination with pro re nata retreatment on evidence of disease activity for 24 months were performed. Therefore, the total study duration was 36 months. RESULTS: The main outcome measures were mean change in the best-corrected visual acuity and central macular thickness by optical coherence tomography, proportion of patients with neovascular complications, and the incidence and severity of ocular and nonocular adverse events. Twenty patients were enrolled in the Rubeosis Anti-VEgf trial, and the mean number of intravitreal treatments administered through Months 24 and 36 were 14.1 and 17.2, respectively. The mean best-corrected visual acuity letters gained were +21.1 and +21.4 at 9 and 36 months, respectively. The mean central macular thickness improved -294 µm from baseline after 9 monthly treatments. Subsequently, after 3 months of observation, the mean central macular thickness increased +203 µm. On initiation of pro re nata ranibizumab retreatment, the mean central macular thickness then improved -191 µm at Month 36 compared with Month 12. Nine patients developed neovascular complications, being diagnosed after a mean of 24-month follow-up (range, 3-44 months), with 2 patients developing neovascularization after completion of the 36-month trial endpoint (at Months 42 and 44 after study enrollment). CONCLUSION: Intravitreal ranibizumab therapy can improve retinal anatomy and vision in eyes with severe central retinal vein occlusion. Despite significant clinical benefit with antivascular endothelial growth factor therapy, the risk of neovascular complications was not ameliorated by vascular endothelial growth factor blockade, but was merely delayed.

ABSTRACT

This case series reports on two patients who developed macular holes while on prostaglandin analogs (PGA) therapy. The first case involves a 63-year-old woman with a history of a macular hole of the left eye that had spontaneously closed. After starting PGA therapy for elevated intraocular pressure, cystoid macular edema formed, which resulted in reopening of the macular hole. The second case involves a 64-year-old man with primary open-angle glaucoma, on PGA therapy, with a newly diagnosed small macular hole of the right eye that closed after cessation of the PGA therapy. These cases demonstrate an association between prostaglandin analogs and the formation or reopening of full-thickness macular holes. [Ophthalmic Surg Lasers Imaging Retina 2024;55:112-115.].

ABSTRACT

Marijuana is a commonly abused illicit substance around the world, and lung injury related to its use has seldom been cited in the literature. Most cases describe marijuana-induced lung injury via vaping and the use of butane hash oil; however, no cases, to our knowledge, have associated lung injury related to marijuana smoke in the form of rolled "blunts" or cigarettes. We describe the case of a patient who presented to the hospital due to chest computed tomography findings demonstrating diffuse bilateral opacifications without signs of systemic inflammatory response syndrome. Bronchoscopy with bronchoalveolar lavage and sputum cultures failed to identify an infectious etiology, and serologies were negative for autoimmune etiologies. We aim to contribute to the limited body of literature describing marijuana-induced lung injury.

ABSTRACT

Herein are reported four eyes among three patients with favorable anti-vascular endothelial growth factor crunch syndrome by which contraction of fibrovascular tissue led to relief of vitreoretinal traction without surgical intervention. This phenomenon led to complete or partial retinal reattachment in two patients with diabetic tractional retinal detachments. These cases represent favorable anatomic outcomes of crunch syndrome secondary to anti-vascular endothelial growth factor pharmacotherapy and are unique compared with most cases, which have been associated with negative outcomes.

ABSTRACT

OBJECTIVE: People with HIV (PWH) experience greater declines in both muscle function and muscle mass with aging. Whether changes in muscle quality and quantity with aging differ between men and women with HIV and the implications on muscle function are not established. DESIGN: In coordinated substudies of the Multicenter AIDS Cohort Study and Women's Interagency HIV Study, participants completed physical function and falls assessments; total trunk/thigh density, inversely related to fatty infiltration, and area were quantified from computed tomography (CT) scans. METHODS: Generalized linear models were used to explore variables affecting density/area, and associations between area/density and physical function and falls. RESULTS: CT scans were available on 387 men (198 PWH) and 184 women (118 PWH). HIV serostatus was associated with greater lateralis, paraspinal, and hamstring area, but lower psoas area and density. Older age and female sex were associated with smaller trunk muscle area and lower density. Both lower muscle area and muscle density were associated with several measures of impaired physical function. The odds of falling were lower with greater hamstring density, but not associated with other measurers of muscle area or density. CONCLUSIONS: In summary, older adults with HIV appear to have smaller and less dense (fattier) psoas, a key component in truncal stability and hip flexion that could have implications on physical function. The longitudinal associations of muscle area and density with physical function require careful investigation, with a particular focus on characteristics and interventions that can preserve muscle area, density, and function over time.

ABSTRACT

There is limited data on the presentation and surgical outcomes of idiopathic macular holes (IMH) for different ethnic and racial groups. Recognition of distinct, clinically-relevant patient subgroups may provide opportunities to identify specific unmet needs including possible barriers to optimal healthcare delivery. Medical records of patients who underwent surgery for IMH (between 2016 and 2022) at a large, urban retina practice were reviewed and self-reported ethnicity (Hispanic and non-Hispanic) and race (Asian, Black, White, and Other) were captured. The primary variables included (1) mean minimum linear diameter (MLD) at presentation and (2) surgical outcome (IMH closure status). Overall, mean MLD for all study eyes (515) was 366.1 µm, and surgical success was achieved in 489 (95.0%) eyes. Hispanic eyes presented with larger mean MLD (p = 0.002) compared to non-Hispanic eyes. Asian, Black, and Other eyes presented with larger mean MLD (p = 0.033, p < 0.001, p < 0.001) when compared to White eyes. The presentation of IMH varied in severity among different ethnic and racial groups. Hispanic patients were found to have worse preoperative visual acuity (VA), longer time to surgery, and larger mean MLD and BD compared to non-Hispanic participants. Black and Other patients were found to have worse VA, time to surgery, and larger mean MLD and BD when compared to White participants.

ABSTRACT

PURPOSE: To assess outcomes among eyes undergoing surgery for recurrent rhegmatogenous retinal detachment (RRD) and investigate variables that correlate with visual and anatomic outcomes. DESIGN: Retrospective, consecutive case series. PARTICIPANTS: Eyes in which initial RRD repair failed that underwent ≥2 surgeries for RRD repair between January 1, 2016, and December 31, 2020. METHODS: A retrospective analysis of eyes that underwent ≥2 RRD repairs. Eyes with etiologies of retinal detachment other than RRD, previous vitreoretinal surgery, and proliferative diabetic retinopathy were excluded. One-way analysis of variance with Tukey honestly significant difference testing and multivariate regression analyses were used to assess statistical significance. MAIN OUTCOME MEASURES: Anatomic success rate and habitual best recorded visual acuity (VA) at postoperative time intervals and at final follow-up. RESULTS: The single-operation success rate (SOSR) among eyes that underwent primary RRD repair over a 5-year period was 92.4% (2021 of 2187 eyes). The remaining 166 eyes (164 patients) in which primary RRD repair failed were included in this study. Although the anatomic success rates after the second and third RRD repairs were lower than the SOSR (71.7% and 68.1%, respectively), the final anatomic success rates did not significantly differ between eyes that underwent ≥2 RRD repairs (range, 90.6%-100%) (P > 0.05), and final anatomic success was achieved in 95.8% of the eyes. The average VA at both postoperative time intervals and final follow-up decreased with an increased total number of RRD repairs. Eyes that received silicone oil endotamponade during the second RRD repair were 20.3% (P = 0.03) and 38.4% (P = 0.04) less likely to require a third RRD repair compared with eyes that received octafluoropropane and sulfur hexafluoride gases, respectively. Eyes that developed a third RRD due to proliferative vitreoretinopathy (PVR) (n = 43) were 110% more likely to require a fourth RRD repair than eyes that developed a third RRD due to a new tear or failure to reattach (n = 4) (P = 0.04). CONCLUSIONS: In this series, the rates of anatomic success appeared consistent after each surgery when multiple reoperations were required for RRD. The VA decreased with an increased total number of RRD repairs, and the endotamponade choice might have affected the risk of additional reoperations. Proliferative vitreoretinopathy was a significant prognostic factor for RRD recurrence.

ABSTRACT

MicroRNAs (miRNAs) are stably present in human serum. The relationship between circulating miRNAs and hepatitis B virus (HBV) infected liver disease has not been previously reported. Applied Biosystems array-based miRNA expression profiling was performed on pooled sera obtained from identified groups of chronic asymptomatic carriers (ASC), patients with chronic hepatitis B (CHB) and HBV-associated acute-on-chronic liver failure (ACLF), as well as healthy controls (HC). Nine miRNAs were verified in more clinical samples by RT-PCR. The correlation between miRNAs expression and the relationship between miRNA levels and clinical characteristics was analysed. Results showed that circulating miRNAs were detected in all disease and control samples, and their numbers increased with symptom severity, from 37 in HC, 77 in ASC, 101 in CHB, to 135 in ACLF. The expression levels of most miRNAs were also up-regulated in HBV-infected patients when compared to HC. Expression of the liver-specific miR-122 was significantly up-regulated in HBV-infected patients. Concomitant regulation of miRNAs not in clusters was disrupted by HBV infection. However, such disruption was not observed for miRNAs in paralogous clusters. Furthermore, the level of miRNAs in the CHB serum was up-regulated most in hepatitis B e antigen-positive patients. The expression levels of miR-122 and miR-194 correlated negatively with the age of patients with CHB or ACLF. Functional analysis showed that miR-122 could inhibit HBV replication in Huh7 and HepG2 cells. In all, our study revealed that a number of miRNAs were differentially expressed during HBV infection and underscored the potential importance of miR-122 in the infection process.
