The Relationship between Ischemic Optic Neuropathy and Internal Carotid Artery Dissection: A Systematic Review.

Background: To evaluate and review the current evidence regarding the association between ischemic optic neuropathy (ION) and internal carotid artery dissection (ICAD). Methods: We systematically reviewed studies according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines (PRISMA), searching three databases (Scopus, Pubmed, and Embase) for relevant articles that clearly described the correlation between ION and ICAD. All studies that examined the association between ICAD and the development of ION were synthesized. Quality assessment using the Newcastle-Ottawa Scale (NOS) and Joanna Briggs Institute (JBI) Critical Appraisal Checklist for Case Reports and Case Series were conducted. Results: Our search yielded 198 manuscripts published in the English language. Following study screening, fourteen studies were selected. The number of participants with ION following ICAD ranged from one to four, with sixteen patients experiencing either anterior ION, posterior ION, or a combination of both. The anterior or posterior ischemic optic neuropathy (AION and PION) patients' ages were 48.75 ± 11.75 and 49.62 ± 12.85, respectively. Fourteen out of sixteen patients experienced spontaneous ICAD, whereas the traumatic etiology was ascertained in two patients. Conclusions: Hence, albeit rare, ophthalmologists should consider ICAD a potential cause of ION, especially in young adults with concomitant cephalic pain and vision reduction.

Ocular Involvement in Systemic Sclerosis: Updated Review and New Insights on Microvascular Impairment.

Systemic sclerosis (SSc) is a chronic multisystemic disease characterized by immunological activation, diffuse vasculopathy, and generalized fibrosis exhibiting a variety of symptoms. A recognized precursor of SSc is Raynaud's phenomenon, which is part of the very early disease of systemic sclerosis (VEDOSS) in combination with nailfold videocapillaroscopy (NVC) impairment. The pathophysiology of ocular involvement, alterations in internal organs, and body integumentary system involvement in SSc patients are complicated and poorly understood, with multiple mechanisms presumptively working together. The most prevalent ocular symptoms of SSc are abnormalities of the eyelids and conjunctiva as well as dry eye syndrome, due to fibroblasts' dysfunction and inflammation of the ocular surface. In particular, lagophthalmos, blepharophimosis limitation of eyelid motion, eyelid telangiectasia, and rigidity or tightening of the lids may affect up to two-third of the patients. In addition, reduction in central corneal thickness, iris defects and higher rates of glaucoma were reported. In the first reports based on retinography or fluorescein angiography, about 50% of SSc patients showed signs of vascular disease: peripheral artery occlusion, thinning of retinal pigment epithelium and choroidal capillaries, ischemic areas surrounded by intraretinal extravasation and microaneurysms, and peripheral capillary non-perfusion. Successively, thanks to the advent of optical coherence tomography angiography (OCTA), several studies highlighted significant impairment of either the choriocapillaris and retinal vascular plexuses, also correlating with NVC involvement and skin disease, even in VEDOSS disease. Given the sensitivity of this technique, ocular micro-vasculopathy may act as a tool for early SSc identification and discriminate between disease stages.

Long-Term results of macular buckle for MTM stage 3-4 With maculoschisis and macular detachment without and With lamellar macular hole.

PURPOSE: To report the long-term anatomical and functional results of macular buckle for Myopic Traction Maculopathy (MTM) in stages 3a, 3b, 4a, and 4b according to the MTM Staging System (MSS). METHODS: Retrospective observational cohort study involving 55 consecutive patients with MTM in stages 3a, 3b, 4a, and 4b who underwent macular buckle (MB). Postoperative outcomes, including optical coherence tomography (OCT) scans to evaluate the MTM stage and its progression, were evaluated 1-month postoperatively (i.e., "intermediate follow-up") and at last follow-up ranging between 6 and 156 months postoperatively (i.e., "final follow-up"). RESULTS: Fifty-five eyes affected by MTM who underwent MB were enrolled. The mean preoperative and postoperative axial length was 31.13 ± 2.14 and 29.73 ± 2.16 mm, respectively (p < 0.01), with a mean axial shift of 1.32 ± 0.77 mm. The mean sample best corrected visual acuity (BCVA) at baseline, intermediate, and final follow-ups was 0.87 ± 0.36, 0.73 ± 0.31, 0.41 ± 0.32 logMar, respectively (p < 0.01). Foveal and retinal anatomical improvements were achieved in 50 (91%) and 53 (96.4%) eyes at intermediate follow-up, respectively. In the final follow-up, 54 (98.2%) and 55 (100%) eyes showed foveal and retinal anatomical improvements, respectively. CONCLUSIONS: MB as a single procedure, when applied to MTM in stages 3a, 3b, 4a, and 4b, leads to significant anatomical and functional improvement. The MTM Staging System allows us to evaluate the best surgical technique and the surgical timing tailored to the different stages to increase the surgery's success and lower the complications of each technique.

Pain experience in patients undergoing topical anesthesia alone versus topical plus intracameral anesthesia during cataract surgery.

PURPOSE: To evaluate and compare the pain experience and discomfort during cataract surgery and over the 24 hours after surgery in patients undergoing either topical anesthesia alone or topical anesthesia plus intracameral anesthesia, provided by using a standard topical anesthesia regimen and a 0.2-mL dose of Mydrane®. METHODS: Prospective study involving 100 patients who underwent cataract surgery receiving either topical anesthesia alone (group 1, n = 50) or topical anesthesia plus intracameral anesthesia (group 2, n = 50) between January 2021 and March 2022. The pain experienced by patients during and after surgery was assessed using a pain scale and a questionnaire. One hour after surgery, patients were asked to rate the intensity of discomfort they experienced throughout the procedure by pointing to a 0-100 Visual Analogue Scale (VAS). RESULTS: According to VAS measurements, patients who underwent surgery under topical anesthesia reported more significant pain than those who underwent surgery under topical anesthesia plus intracameral anesthesia during and over the 24 hours after surgery. (p = 0.02 and p = 0.01, respectively). Patients undergoing topical anesthesia had 2.34-fold greater odds of having pain during surgery [95% Confidence Interval (CI): 1.58-5.25, p = 0.03]. CONCLUSIONS: Topical anesthesia plus intracameral anesthesia lower intraoperative and postoperative pain levels, improving patient cooperation and representing a useful analgesic delivery method in cataract surgery.

Can the Modified Frailty Index (mFI) Predict Intraoperative and Postoperative Complications in Older Women with Endometrial Cancer Undergoing Laparoscopic or Robotic Surgery? A Multicenter Observational Study.

BACKGROUND: This study aims to evaluate the strength of the association between frailty and intraoperative/postoperative complications in patients undergoing minimally invasive surgery (MIS) for endometrial cancer. METHODS: In this retrospective observational multicenter cohort study, frailty was defined beforehand by a modified frailty index (mFI) score of ≥3. Multiple logistic regressions were performed to investigate possible preoperative predictors-including frailty, age, and body mass index-of intraoperative and early (within 30 days from surgery) or delayed (beyond 30 days from surgery) postoperative complications. RESULTS: The study involved 577 women, of whom 6.9% (n = 40) were frail with an mFI ≥ 3, while 93.1% (n = 537) were non-frail with an mFI of 0-2. Frail women had a significantly higher rate of intraoperative complications (7.5% vs. 1.7%, p = 0.01), with odds 4.54 times greater (95% CI: 1.18-17.60, p = 0.028). There were no differences in the rate of early postoperative complications (15% vs. 6.9%, p = 0.06) and delayed postoperative complications (2.5% vs. 3.9%, p = 0.65) for frail versus non-frail patients. The odds of early postoperative complications increased by 0.7% (95% CI: 1.00-1.15) for every one-unit increase in age (p = 0.032). CONCLUSIONS: Frailty was associated with a significantly higher risk of intraoperative complications in older women undergoing MIS for endometrial cancer. Likewise, increasing age was an independent predictor of early postoperative complications. Our findings support the practice of assessing frailty before surgery to optimize perioperative management in this patient population.

Autologous anterior lens capsule flap and serum transplant in managing idiopathic and refractory full-thickness macular holes.

PURPOSE: To report the results of pars plana vitrectomy (PPV) with inner limiting membrane (ILM) peeling alongside phacoemulsification and intraocular lens (IOL) implantation with autologous anterior lens capsule flap (ALCF) and autologous serum transplantation (AST) into full-thickness macular holes (FTMH) and 14% perfluoropropane (C3F8) tamponade for idiopathic and refractory FTMHs. METHODS: Retrospective study involving eleven patients with idiopathic FMTHs and seven with refractory FMTHs after standard surgery with PPV, ILM peeling, and gas tamponade. All eyes underwent a 'combination procedure' of PPV with ILM peeling alongside phacoemulsification and IOL implantation with autologous ALCF and AST into the FTMH and 14% C3F8 tamponade. A face-down position for one week was recommended. RESULTS: The mean preoperative FMTH size was 558.95 ± 186.30 µm. Seven patients aged 64 ± 5 years had a refractory FMTH and eleven patients with a mean age of 63.72 ± 4.97 years had an idiopathic FMTH. The main BCVA improvement six months postoperatively was 0.3 ± 0.29 logMAR. Seventeen macular holes fully closed six months postoperatively, with one FTMH closure failure because of a retinal detachment. CONCLUSIONS: ALCF transplantation alongside AST may help to improve the closure rate and visual outcomes in both idiopathic and refractory FMTHs.

A Case of Traumatic Submacular Hemorrhage Treated with tPA and Pneumatic Displacement.

This is a case of a 31-year-old female who presented to the emergency department at a London teaching hospital with a 24-h history of visual loss following an assault. The ophthalmological routine examination showed a submacular hemorrhage (SMH), and a computerized tomography scan demonstrated a displaced orbital floor fracture with inferior rectus entrapment and a medial wall fracture. To induce displacement of the SMH, intravitreal injection of 0.25 µg tissue plasminogen activator (tPA) was combined with 0.3 mL of intravitreal 100% perfluoropropane (C3F8) gas. At the 1-day follow-up, there was an inferotemporal displacement of the blood clot, and visual acuity improved from hand motions to 6/5 within 3 months. No complications occurred over 2 years of follow-up, with a final visual acuity of 6/5. This case shows us that intravitreal tPA and gas appear safe and effective as a treatment for traumatic SMHs. Furthermore, our results demonstrate that prompt treatment leads to favorable anatomical and functional outcomes.

Preoperative evaluation of the elderly patient.

Nowadays, the pre-operative evaluation of older patients is a critical step in the decision-making process. Clinical assessment and care planning should be considered a whole process rather than separate issues. Clinicians should use validated tools for pre-operative risk assessment of older patients to minimize surgery-related morbidity and mortality and enhance care quality. Traditional pre-operative consultation often fails to capture the pathophysiological and functional profiles of older patients. The elderly's pre-operative evaluation should be focused on determining the patient's functional reserve and reducing any possible peri-operative risk. Therefore, older adults may benefit from the Comprehensive Geriatric Assessment (CGA) that allows clinicians to evaluate several aspects of elderly life, such as depression and cognitive disorders, social status, multi-morbidity, frailty, geriatric syndromes, nutritional status, and polypharmacy. Despite the recognized challenges in applying the CGA, it may provide a realistic risk assessment for post-operative complications and suggest a tailored peri-operative treatment plan for older adults, including pre-operative optimization strategies. The older adults' pre-operative examination should not be considered a mere stand-alone, that is, an independent stage of the surgical pathway, but rather a vital step toward a personalized therapeutic approach that may involve professionals from different clinical fields. The aim of this review is to revise the evidence from the literature and highlight the most important items to be implemented in the pre-operative evaluation process in order to identify better all elderly patients' needs.

The Role of the Intraoperative Optical Coherence Tomography for Vitreoretinal Surgery in a Real-Life Setting.

BACKGROUND: To descriptively report the advantages and the feasibility of microscope-integrated intraoperative optical coherence tomography (i-OCT) in managing different vitreoretinal diseases in a real-life setting. METHODS: We conducted an observational retrospective study involving 265 eyes that underwent elective retinal surgery and intraoperative OCT between 1 September 2018 and 1 October 2022 at Eyecare Clinic (Brescia, Italy). RESULTS: 52 epiretinal membranes, 30 retinal detachments, 60 high myopic eyes, 30 choroidal transplants, 40 macular holes, and 32 vitreo-proliferative retinopathies underwent vitreoretinal surgery and intraoperative OCT scans. The i-OCT was a useful diagnostic exam for all cases and significantly influenced our surgical management. CONCLUSIONS: i-OCT is a helpful surgical tool in ophthalmic surgery as it provides real-time feedback of tissue anatomy to surgeons, thereby guiding decision-making. Moreover, it provides additional information on the microarchitectural changes after instrument-tissue interactions, further guiding procedures when necessary and possibly reducing unessential surgical maneuvers.

Faricimab: Transforming the Future of Macular Diseases Treatment - A Comprehensive Review of Clinical Studies.

Degenerative eye conditions such as age-related macular degeneration (AMD), diabetic retinopathy, and retinal vein occlusion are major contributors to significant vision loss in developed nations. The primary therapeutic approach for managing complications linked to these diseases involves the intravitreal delivery of anti-vascular endothelial growth factor (VEGF) treatments. Faricimab is a novel, humanised, bispecific antibody that simultaneously binds all VEGF-A isoforms and Angiopoietin-2, which has been approved by regulatory agencies, such as the US Food and Drug Administration (FDA), the UK Medicines and Healthcare products Regulatory Agency (MHRA) and the European Medicines Agency (EMA), for the treatment of neovascular AMD and diabetic macular oedema (DMO). Intravitreal faricimab holds the promise of reducing the treatment burden for patients with these conditions by achieving comparable or superior therapeutic outcomes with fewer clinic visits. The scope of faricimab's application includes addressing complex macular conditions such as DMO. This review intends to elucidate the distinctive pharmacological characteristics of faricimab and provide an overview of the key clinical trials and real-world studies that assess its effectiveness and safety in treating degenerative macular diseases.

SCLERAL FIXATION OF CARLEVALE INTRAOCULAR LENS: A Systematic Review and Meta-Analysis.

PURPOSE: The mean change in best-corrected visual acuity (BCVA), intraocular pressure, and endothelial cell counts after intraocular lens (IOL) implantation and the incidence rate of postoperative complications were estimated by systematic review and meta-analysis to assess the surgical and refractive outcomes of the sutureless scleral fixation Carlevale IOL. METHODS: A literature search was conducted using PubMed, Embase, and Scopus. The weighted mean difference (WMD) was used to present the mean change in BCVA, intraocular pressure, and endothelial cell count after IOL implantation, whereas a proportional meta-analysis was used to estimate the pooled incidence rate of postoperative complications. RESULTS: In the meta-analysis of 13 studies involving 550 eyes, the pooled WMD of the mean change in BCVA showed a significant improvement in BCVA in patients who underwent Carlevale IOL implantation (WMD = 0.38, 95% confidence interval: 0.30-0.46, P < 0.001; heterogeneity [I 2 ] = 52.02%). The subgroup analyses indicated that the mean change in BCVA was not significantly higher according to the last follow-up visit, with no statistically significant subgroup effect ( P = 0.21) (WMD up to 6 months: 0.34, 95% confidence interval: 0.23-0.45, I 2 = 58.32%, WMD up to 24 months: 0.42, 95% confidence interval: 0.34-0.51, I 2 = 38.08%). In the meta-analysis of 16 studies involving 608 eyes, the pooled incidence rate of postoperative complications was equal to 0.22 (95% confidence interval: 0.13-0.32, I 2 = 84.87, P ≤ 0.001). CONCLUSION: Carlevale IOL implantation represents a reliable method of restoring vision in eyes with missing capsular or zonular support.

Cataract surgery training: Report of a trainee's experience.

BACKGROUND: To report a trainee's experience gained in the cataract extraction training program after the COVID-19 pandemic. METHODS: An ophthalmologist was trained in phacoemulsification and intraocular lens (IOL) implantation in the ETAPE foundation, Eye Center, Cairo for a period of 4 weeks by three expert cataract surgeons. The training was tailored to the previous trainee's experience according to his residency logbook and supervised by one expert cataract surgeon. The training included didactic lectures, clinical observations, and hands-on practical experience. In addition, the trainee was provided with a logbook to record details of patients operated on and procedures observed. RESULTS: The trainee performed 58 phacoemulsification surgery with IOL implantation and two extracapsular cataract extraction over the 4 weeks. Seven patients underwent intraoperative complications. Surgical time (ST) improved from 48.77 ± 9.65 min in the 1stweek to 19.34 ± 1.31 min during the last week of training (P = 0.046). Poisson regression showed that patients affected by less severe cataracts were more likely to exhibit a lower incidence of complications than patients affected by more severe cataracts. In addition, patients operated on during the 1stweek were more likely to show a higher incidence of complications than those operated on during the last week. CONCLUSIONS: The 4-week surgical training effectively improved surgical confidence and micro incisional skills according to ST reduction and complication rate occurrence. Ophthalmologists benefit from enhancing their cataract skills in a short time following a well-structured cataract extraction course. This could undoubtedly lead to improved surgical outcomes for patients undergoing cataract extraction.

Intravitreal Fluocinolone Acetonide Implant (ILUVIEN®) for the Treatment of Retinal Conditions. A Review of Clinical Studies.

Fluocinolone acetonide (FAc) intravitreal implant (Iluvien®) is a corticosteroid implant indicated for the treatment of diabetic macular oedema (DMO) in patients who have previously received conventional treatment without good response, non-infectious posterior uveitis, and as an off-label treatment of the macular oedema secondary to retinal vein occlusion. FAc is a non-biodegradable 0.19 mg intravitreal implant which is designed to release FAc over 3 years at a rate of approximately 0.2 mcg per day. The aim of this review is to describe the special pharmacological properties of Iluvien and display the outcomes of the most important clinical trials and real-world studies regarding its efficacy and safety for the management of the above retinal disorders.

Sympathetic Ophthalmia after Vitreoretinal Surgery without Antecedent History of Trauma: A Systematic Review and Meta-Analysis.

BACKGROUND: To evaluate the morbidity frequency measures in terms of the cumulative incidence of sympathetic ophthalmia (SO) triggered by single or multiple vitreoretinal (VR) surgery procedures in eyes without an antecedent history of trauma and previous ocular surgery, except for previous or concomitant uneventful lens extraction, and to further investigate the relationship between VR surgery and SO. METHODS: A literature search was conducted using PubMed, Embase, and Scopus from inception until 11 November 2022. The Joanna Briggs Institute (JBI) critical appraisal checklist for the case series and the Newcastle-Ottawa Scale were used to assess the risk of bias. The research was registered with the PROSPERO database (identifier, CRD42023397792). Meta-analyses were conducted using the measurement of risk and a 95% confidence interval (CI) for each study. RESULTS: A random-effect meta-analysis demonstrated that the pooled cumulative incidence of SO triggered by single or multiple VR surgery procedures in eyes without an antecedent history of trauma and previous ocular surgery, except for previous or concomitant uneventful lens extraction among patients who developed SO regardless of the main trigger, was equal to 0.14 with a CI between 0.08 and 0.21 (I2 = 78.25, z: 7.24, p < 0.01). The pooled cumulative incidence of SO triggered by single or multiple VR surgery procedures in eyes without an antecedent history of trauma and previous ocular surgery, except for previous or concomitant uneventful lens extraction among patients who underwent VR surgery, was equal to 0.03 for every 100 people, with a confidence interval (CI) between 0.02% and 0.004% (I2 = 27.77, z: 9.11, p = 0.25). CONCLUSIONS: Despite postsurgical SO being a rare entity, it is a sight-threatening disease. VR surgery should be viewed as a possible inciting event for SO and considered when counseling patients undergoing VR surgery.

Postoperative complications after successful primary rhegmatogenous retinal detachment repair.

BACKGROUND: To evaluate the incidence and risk factors for cystoid macular edema (CME) and epiretinal membrane (ERM) development after surgery for primary rhegmatogenous retinal detachment (RRD). METHODS: Retrospective observational cohort study involving 62 consecutive patients with primary RRD who underwent RRD repair with either scleral buckling (SB) or pars plana vitrectomy (PPV). SB was used in young phakic patients without posterior vitreous detachment (PVD), high myopic patients, and RRD associated with either anterior or inferior retinal tears. PPV was preferred over SB in pseudophakic patients or those with media opacity and posterior breaks that precluded the SB approach. After surgery, the macular changes, including CME and ERM development, were evaluated 3 and 6 months postoperatively. Phacoemulsification and intraocular lens (IOL) implantation were performed in phakic patients where media opacity or lens bulging did not allow the surgeon to perform surgical maneuvers. The inner limiting membrane (ILM) peeling was randomly performed in the macula-off and the macula-on RRD "pending foveal detachment" subgroup. RESULTS: Sixty-two eyes affected by RRD who underwent SB or PPV were enrolled. CME occurred in 33.3% of the PPV group regardless of the ERM formation. No CME cases were found in the SB group. Macula-off RRD increased the risk of CME by odds ratio (OR) = 4.3 times compared to macula-on RRD regardless of the surgical procedure (p = 0.04). Macula-off status increased the risk of CME of OR = 1.73 times compared to macula-on in the PPV subgroup (p = 0.4). Combined cataract surgery and PPV increased the risk of CME by OR = 3.3 times (p = 0.16) compared to PPV alone, and ILM peeling increased the risk of postoperative CME by OR = 1.8 times (p = 0.37). ERM occurred in 28% of patients who did not undergo ILM peeling, and 29.42% of those who underwent ILM peeling developed ERM (p = 0.6). CONCLUSIONS: The risk of postoperative CME was higher in patients with macula-off than in macula-on RRD and in those with macula-off RRD who underwent PPV. The SB would be advisable in patients with RRD sparing the macula. Furthermore, despite having several advantages, the combined phacoemulsification plus IOL implantation and PPV highly increased the risk of postoperative CME.

Comparison of novel digital microscope using integrated intraoperative OCT with Ngenuity 3D visualization system in phacoemulsification.

OBJECTIVE: To compare surgical efficiency, visual and physical comfort, and safety profile of the ARTEVO 800 Digital Microscope (Carl Zeiss Meditec AG, Jena, Germany) and the Ngenuity 3D Visualization System (Alcon Laboratories Inc, Fort Worth, TX) in cataract surgery. DESIGN: Cross-sectional study. PARTICIPANTS: One hundred consecutive phacoemulsification cataract surgeries performed by five surgeons from June 1, 2020, to November 1, 2020. METHODS: For each case, the surgeons answered a 2-section questionnaire (before and after intervention) to collect data on cataract severity or grade, surgical risk, chosen three-dimensional (3D) visualization system, surgical complications, and the visual or physical discomfort experienced during the procedure. RESULTS: Each of the 5 surgeons performed 20 surgeries (N = 100) using either the ARTEVO 800 Digital Microscope (N = 50) or the Ngenuity Visualization System (N = 50). Mean duration of the surgical procedure was 17.07 ± 4.80 minutes, and none of the surgeons ever switched to the classical microscope. In addition, 40% of surgeries were considered at low risk, 30% at intermediate risk, and 30% at high risk. The Zoom, Focus, and XY commands were used 1-3 times, respectively, during 76 (p = 0.34), 73 (p = 0.49), and 76 (p = 0.64) interventions. Surgical uncertainty and operative fluency were similar using both systems (p = 0.53 and p = 0.19). We observed 14 intraoperative complications, 9 using Ngenuity and 5 using the ARTEVO 800. Surgeon's visual comfort (p = 0.79), colour or brightness perception (p = 0.82), and visual impairment (p = 0.62) during surgery were similar for both systems. Headache, backache, and other musculoskeletal problems were reported, respectively, after 14 (p = 0.79), 11 (p = 0.99), and 8 (p = 0.44) procedures. CONCLUSION: Both the Ngenuity 3D Visualization System (Alcon Laboratories Inc) and the ARTEVO 800 Digital Microscope (Carl Zeiss Meditec AG) provided comparable operative speed and overall surgical comfort during cataract surgery.

Efficacy of the intracamerally administered mydriatics for cataract surgery in patients with primary open-angle glaucoma.

PURPOSE: To compare Mydrane®, mydriatic eye drops, and Mydriasert® in terms of pupil site stability, surgical time, visual field, and anterior chamber configuration modifications among patients with primary open-angle glaucoma (POAG) during cataract extraction surgery. METHODS: Retrospective analysis of sixty patients with POAG and cataract who underwent elective cataract extraction. All patients underwent routine ophthalmic examinations, including automatic visual field examination, anterior chamber configuration, specular microscopy, and arterial blood pressure measurement prior to surgery, and 24 h and 30 days postoperatively. All cataract surgeries were video-recorded and all measurements were performed using a media player. Patients divided into groups 1, 2, and 3 (n = 20 in each group) received topical mydriatic eye drops, Mydriasert®, and an intracameral injection of Mydrane®, respectively, immediately after the first incision. RESULTS: The mean change in pupil size from just before capsulorhexis to the end of surgery was 0.43 ± 0.09, 0.42 ± 0.08, and 0.36 ± 0.02 mm in groups 1, 2, and 3, respectively. The mean surgery duration was similar among all the groups. The baseline main cell density slightly decreased at 24 h and remained stable for 30 days postoperatively. The mean deviation and pattern standard deviation remained stable at 1 month after surgery. At 24 h after surgery, the nasal irido-corneal angle, temporal-iridocorneal angle, and anterior chamber depth increased compared with the baseline, remaining stable for 30 days after surgery. CONCLUSIONS: Mydrane® produced adequate and stable mydriasis as effectively as produced by Mydriasert® and topical eye drops.

NEW ARTIFICIAL INTELLIGENCE ANALYSIS FOR PREDICTION OF LONG-TERM VISUAL IMPROVEMENT AFTER EPIRETINAL MEMBRANE SURGERY.

PURPOSE: To predict improvement of best-corrected visual acuity (BCVA) 1 year after pars plana vitrectomy for epiretinal membrane (ERM) using artificial intelligence methods on optical coherence tomography B-scan images. METHODS: Four hundred and eleven (411) patients with Stage II ERM were divided in a group improvement (IM) (≥15 ETDRS letters of VA recovery) and a group no improvement (N-IM) (<15 letters) according to 1-year VA improvement after 25-G pars plana vitrectomy with internal limiting membrane peeling. Primary outcome was the creation of a deep learning classifier (DLC) based on optical coherence tomography B-scan images for prediction. Secondary outcome was assessment of the influence of various clinical and imaging predictors on BCVA improvement. Inception-ResNet-V2 was trained using standard augmentation techniques. Testing was performed on an external data set. For secondary outcome, B-scan acquisitions were analyzed by graders both before and after fibrillary change processing enhancement. RESULTS: The overall performance of the DLC showed a sensitivity of 87.3% and a specificity of 86.2%. Regression analysis showed a difference in preoperative images prevalence of ectopic inner foveal layer, foveal detachment, ellipsoid zone interruption, cotton wool sign, unprocessed fibrillary changes (odds ratio = 2.75 [confidence interval: 2.49-2.96]), and processed fibrillary changes (odds ratio = 5.42 [confidence interval: 4.81-6.08]), whereas preoperative BCVA and central macular thickness did not differ between groups. CONCLUSION: The DLC showed high performances in predicting 1-year visual outcome in ERM surgery patients. Fibrillary changes should also be considered as relevant predictors.

Is the visual impairment a risk factor for frailty in older adults? A systematic review and meta-analysis of 10-year clinical studies.

BACKGROUND: Frailty is linked to poor health outcomes later in life. Recent research suggests that visual loss is a possible modifiable risk factor for frailty. AIMS: To analyze the relationship between visual impairment (VI) and frailty and investigate whether it can increase the risk of frailty in older adults. METHODS: We performed a systematic review and meta-analysis of cohort studies following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We systematically searched PubMed, Embase, and Scopus databases for relevant studies published between 2012 and 2022 that clearly described VI and frailty measurement methods. Cross-sectional and longitudinal studies that examined the associations between VI and the existence of frailty in adults aged 65 years or older were synthesized. Meta-analyses were conducted using the measurement of risk and a 95% confidence interval for each study. Quality assessment using the Newcastle-Ottawa Scale (NOS), risk of bias, heterogeneity, and sensitivity analyses were also conducted. RESULTS: Our search identified 1074 manuscripts published in the English language between 1 January 2012 and 9 June 2022. After studies screening, seventeen articles, including 22,192 participants and 3624 cases of frailty, were selected. A random-effect meta-analysis demonstrated a significant association between visual impairment and the risk of frailty (OR 2.13; 95% CI 1.67-2.72). The quality rating of the cross-sectional studies averaged 8.33 (95% CI 7.77-8.89) of the maximum score on the NOS. CONCLUSIONS: Visual impairment increases the risk of frailty in later life and should be accurately assessed in frail older adults.
