The Frequency of Intraocular Pressure Elevation, Incidence of Secondary Glaucoma, and Surgical Treatment With Postoperative Complications in Pediatric and Adult Patients With Uveitis.

Purpose To determine the etiology and anatomic localization of uveitis, the frequency of intraocular pressure (IOP) elevation, and the type of secondary glaucoma and to assess the medical, surgical, and postoperative complications in adult and pediatric patients with acute or chronic uveitis. Methods A total of 307 eyes of 186 patients who were followed up in the Uvea-Behçet Unit of the Ophthalmology Department, Erciyes University, Turkey, were included in the study. Demographic, ocular, and systemic data were recorded; ophthalmological examinations were performed; and recurrences and complications of uveitis were identified. The eyes with IOP over 22 mmHg, types of secondary glaucoma, their etiologies, efficiency of medical and surgical treatments, and complications were recorded. Results The mean age was 33 ± 12 years (range: 6-65). Of the 186 patients, diagnoses were as follows: idiopathic uveitis in 84 (45.2%), Behçet disease in 65 (34.9%), ankylosing spondylitis in eight (4.3%), juvenile idiopathic arthritis in five (2.7%), herpetic keratouveitis in three (1.6%), Fuchs iridocyclitis in three (1.6%), Vogt-Koyanagi-Harada syndrome in three (1.6%), tuberculosis uveitis in three (1.6%), Crohn disease in three (1.6%), ocular toxoplasmosis in two (1.1%), multiple sclerosis in two (1.1%), Lyme disease in two (1.1%), rheumatoid arthritis in two (1.1%) and tubulointerstitial nephritis in one patient (0.5%). Secondary glaucoma was detected in 67 (21.9%) of 307 eyes, which developed in 13.7% and 26.8% of the eyes with acute and chronic uveitis, respectively. Of 67 eyes, it was open-angle glaucoma in 58 (86.5%), angle-closure glaucoma in six (9.0%), and neovascular glaucoma in three (4.5%). Control of IOP was achieved by medical therapy in 53 eyes (79.1%) and by surgery in 12 eyes (17.9%), whereas evisceration was required in two eyes (3.0%). Laser iridotomy was performed in four eyes (33.4%), trabeculectomy with mitomycin-C (MMC) in six eyes (50.0%), laser iridotomy plus trabeculectomy with MMC in one eye (8.3%), and express mini shunt implantation in one eye (8.3%). After surgery, IOP was controlled without anti-glaucomatous agents in six eyes (50%) and with anti-glaucomatous agents in the remaining six eyes (50.0%). Conclusion Secondary glaucoma is one of the most important complications of uveitis and may result in severe visual impairment. Early diagnosis and appropriate treatment can prevent these potential complications.

Effect of adalimumab on choroidal thickness and choroidal vascularity index in eyes with non-infectious uveitis using enhanced-depth imaging optical coherence tomography.

OBJECTIVE: To evaluate the effect of adalimumab (ADA) on choroidal thickness (ChT) and choroidal vascularity index (CVI) in eyes with non-infectious uveitis (NIU). METHODS: Thirty-seven eyes with NIU including Behçet disease (BD), sarcoidosis, ankylosing spondylitis (AS), juvenile idiopathic arthritis and idiopathic arthritis, 38 eyes of non-uveitic (NU) patients including BD, AS and rheumatoid arthritis, and 40 healthy control eyes were included. ADA was used for anti-TNF-naive adult (80 mg) or paediatric (40 mg) patients with refractory NIU, then 40 mg every 2-week (20 mg in children<30 kg) with controls at weeks 1, 4, 12, and 24. Images were used to measure central, nasal, and temporal ChT, and the luminal area (LA), stromal area, and total choroidal area (TCA) were analysed using enhanced-depth imaging optical coherence tomography (EDI-OCT) by ImageJ software. The CVI was then calculated as the ratio of LA to TCA. RESULTS: Mean ages were similar between the groups. Mean (SE) subfoveal ChT measurements for each location were also similar (for each, p > 0.05). However, calculated CVI values in eyes with NIU (0.63 ± 0.007) were significantly (p < 0.001) lower than NU eyes (0.66 ± 0.006) and controls (0.70 ± 0.007) (p < 0.001). Moreover, CVI was significantly lower in NU eyes compared to controls (p < 0.001). There were no significant CVI changes between the consecutive visits after ADA therapy in eyes with NIU (for each, p > 0.05). CONCLUSIONS: Decreased CVI in NIU and NU eyes indicates that systemic inflammation affects the choroidal vasculature and perfusion both in the presence and absence of ocular involvement. Although CVI may be used as a possible novel tool in monitoring ocular involvement and progression of NIU, CVI does not seem to be a biomarker for treatment monitoring in NIU.

Role of the brain-sparing effect on retinopathy of prematurity in newborns with fetal growth restriction.

INTRODUCTION: This study aimed to investigate the role of the brain-sparing effect (BSE) on retinopathy of prematurity (ROP) in fetal growth restriction (FGR). METHODS: In this retrospective study, 127 pregnant women were divided into two groups considering the cerebroplacental ratio (CPR): FGR with abnormal CPR group (n = 74) and the appropriate for gestational age with normal Doppler group (n = 53). CPR was computed using the pulsatility index (PI) and resistance index (RI) to quantitate the waveforms [middle cerebral artery (MCA) PI/umbilical artery (UA) PI and MCA RI/UA RI: a result <1 was taken into account as abnormal]. ROP screening results of newborns were recorded from electronic files. RESULTS: After adjusting for co-variants, BSE was not related to ROP (adjusted odds ratio [aOR], 1.06; 95% confidence interval [CI], 0.23-4.95). Gestational age at delivery <30 weeks (aOR, 2.55; 95% CI, 1.04-6.93) and birth weight <1500 g (aOR, 5.15; 95% CI, 1.15-25.2) were independently associated with ROP. Preeclampsia, emergency cesarean section birth, or 48 h completion after the first steroid administration were not associated with ROP. CONCLUSIONS: Gestational age at delivery <30 weeks and birth weight <1500 g are independent risk factors for ROP in FGR whereas the BSE is not a risk factor.

Automated evaluation of parapapillary choroidal microvasculature in crowded optic discs: a controlled, optical coherence tomography angiography study.

AIM: To compare superficial and deep vascular properties of optic discs between crowded discs and controls using optical coherence tomography angiography (OCT-A). METHODS: Thirty patients with crowded discs, and 47 control subjects were enrolled in the study. One eye of each individual was included and OCT-A scans of optic discs were obtained in a 4.5×4.5 mm2 rectangular area. Radial peripapillary capillary (RPC) density, peripapillary retinal nerve fiber layer (pRNFL) thickness, cup volume, rim area, disc area, cup-to-disc (c/d) area ratio, and vertical c/d ratio were obtained automatically using device software. Automated parapapillary choroidal microvasculature (PPCMv) density was calculated using MATLAB software. When the vertical c/d ratio of the optic disc was absent or small cup, it was considered as a crowded disc. RESULTS: The mean signal strength index of OCT-A images was similar between the crowded discs and control eyes (P=0.740). There was no difference in pRNFL between the two groups (P=0.102). There were no differences in RPC density in whole image (P=0.826) and peripapillary region (P=0.923), but inside disc RPC density was higher in crowded optic discs (P=0.003). The PPCMv density in the inner-hemisuperior region was also lower in crowded discs (P=0.026). The pRNFL thickness was positively correlated with peripapillary RPC density (r=0.498, P<0.001). The inside disc RPC density was negatively correlated with c/d area ratio (r=-0.341, P=0.002). CONCLUSION: The higher inside disc RPC density and lower inner-hemisuperior PPCMv density are found in eyes with crowded optic discs.

Efficacy and Safety of Adalimumab in Patients with Behçet Uveitis: A Systematic Review and Meta-Analysis.

PURPOSE: To examine the long-term efficacy and safety of adalimumab (ADA) in patients with Behçet uveitis (BU). METHODS: A systematic review and meta-analysis of observational studies was performed. Pooled results are presented as mean difference or standardized mean difference (std diff) and 95% confidence intervals (CI). Visual acuity (VA), intraocular inflammation grade, central macular thickness, corticosteroid (CS) sparing effect and adverse events were evaluated. RESULTS: Ten studies were included finally for quantitative and qualitative synthesis. ADA therapy resulted in 0.124 (95%CI: 0.084, 0.165) logMAR improvement in VA. In addition, ADA therapy resulted in decreased grade of intraocular inflammation [std diff, -1.187 (95%CI: -1.508, -0.866)] and macular thickness [std diff, -0.564 (95%CI: -0.843, -0.286)] and caused a decrease in CS dosage [std diff, -1.809 (95%CI: -2.420, -1.198)]. The pooled rate of overall adverse events for ADA in 301 patients was 8.5% (95%CI: 0.039, 0.177). CONCLUSION: ADA is an efficient therapy that improves VA and controls intraocular inflammation, macular edema and retinal vasculitis. As the disease exposure time increased, improvement in VA was less. The safety and CS-sparing effect of ADA were demonstrated with few adverse effects. The results provided evidence that ADA can be used safely and efficiently as the first-line drug in patients with BU.

Efficacy and Safety of Different Types of Intraocular Pressure-Lowering Surgeries in Patients with Primary Angle Closure (PAC) or PAC Glaucoma: Systematic Review and Network Meta-Analysis of Randomized Clinical Trials.

OBJECTIVE: To compare the intraocular pressure (IOP)-lowering effect of different types of surgery available in the literature using a network meta-analysis (NMA) based on a systematic review. METHODS: PubMed and the Cochrane database were searched. Randomized clinical trials involving surgical interventions for high IOP for PAC (primary angle closure) or PACG (primary angle closure glaucoma) were included. Descriptive statistics and outcomes were extracted. Bayesian NMA was performed to compare the IOP-lowering effect and the change in the number of antiglaucoma drugs required between baseline and endpoint, as well as success rates. RESULTS: This NMA included 21 articles with 1237 eyes with PAC or PACG. Interventions were characterised as phacoemulsification (phaco), trabeculectomy, goniosynechialysis (GSL) with viscoelastic or blunt device, goniosurgery (GS) (trabeculotomy or goniotomy), micro-bypass stent (Istent®), endocyclophotocoagulation (ECPL) or various combinations of these procedures. Phaco+GSL [-1.73 (95%CrI: -3.53 to -0.13)] and phaco+GSL+GS [-3.92 (95%CrI: -6.91 to -1.31)] provided better IOP lowering effects than phaco alone. Phaco+trabeculectomy [-3.11 (95%CrI: -5.82 to -0.44)] was inferior to phaco+GSL+GS. Phaco+trabeculectomy [-0.45 (95%CrI: -0.81 to -0.13)] provided a better outcome in terms of reducing the need for antiglaucoma drug compared to phaco alone. There were no differences between the other surgeries in terms of reduction of antiglaucoma drug number and IOP lowering effect. Success rates were similar for all surgical procedures. CONCLUSIONS: Phaco+GSL+GS showed the most promising results for lowering IOP. Phaco+trabeculectomy resulted in a significant reduction in the number of antiglaucoma drugs compared to phaco alone.

Parapapillary choroidal microvasculature in retrobulbar optic neuritis: An optical coherence tomography angiography study.

PURPOSE: To compare superficial and deep vascular characteristics of the optic disc in retrobulbar optic neuritis using optical coherence tomography angiography (OCT-A). METHODS: Nineteen patients with unilateral non-infectious retrobulbar neuritis were included in the study. The contralateral eyes of each patient were served as controls. OCT-A scans of the optic discs were performed in a 4.5 × 4.5 mm rectangular area, while macular OCT-A scans were performed in a 6 × 6 mm rectangular area. Various parameters, including radial peripapillary capillary (RPC) density, peripapillary retinal nerve fibre layer (pRNFL) thickness, cup volume, rim area, disc area, cup-to-disc (c/d) area ratio, and vertical and horizontal c/d ratios were automatically obtained using the instrument software. The density for superficial capillary plexus (SCP) and deep capillary plexus (DCP) were assessed using macular OCT-A. Parapapillary choroidal microvascular (PPCMv) density was calculated using MATLAB software. RESULTS: Parafoveal inferior, perifoveal total and inferior SCP densities were significantly decreased in eyes with optic neuritis when compared with contralateral control eyes in OCT-A measurements (respectively, p = 0.027, p = 0.041, p = 0.045). The axial lengths, (p = 0.72), vertical and horizontal cup-disc ratios, and disc area, cup-disc areas, cup volumes, and pRNFL thicknesses between the groups were similar (for each, p>0.05). CONCLUSIONS: This study demonstrated for the first time that patients with retrobulbar optic neuritis had decreased SCP densities, though it did not cause any changes in PPCMv density.

Evaluation of histologic, antiapoptotic and antioxidant effects of melatonin against the acute ocular toxicity of Cisplatin.

This study aimed to investigate the protective effect of melatonin against the acute toxicity of cisplatin in ocular tissues. The eyes of 40 rats were divided into 4 groups: Control group (10 rats), Melatonin (Mel) group (10 rats), Cisplatin (Cis) group (10 rats), Melatonin (Mel) + Cisplatin (Cis) group (10 rats). Retina, cornea, and ciliary body tissues were examined after hematoxylin-eosin staining of sections obtained from the eyes and were scored for disorganization and degeneration. Apoptotic cells were counted for the retina, cornea, and ciliary body with the TUNEL (Terminal deoxynucleotidyl transferase dUTP nick end labeling) method. The total antioxidant status (TAS) / total oxidant status (TOS) of homogenized eye tissues were measured. While apoptotic cells were found to increase in the cornea of the Cisplatin (Cis) group, no difference was found regarding the retina and ciliary body cell count. An increased number of apoptotic cells in the cornea of the Cis group was found while there was a decrease in the group where Cisplatin and Melatonin were administered together (Mel+Cis group). There was no statistically significant difference amongst groups for TOS or TAS. Melatonin had a partial protective effect against histological damage.

Choroidal vascularity index and submacular choroidal thickness in patients with Behçet disease assessed with enhanced-depth OCT.

PURPOSE: To investigate changes in the choroid using the choroidal vascularity index (CVI) and choroidal thickness (ChT) in patients with ocular (OBD) and non-ocular Behçet disease (non-ocular BD). METHODS: Sixty-eight OBD patients, 40 non-ocular BD patients, and 40 healthy control subjects were included. ChT was measured using optical coherence tomography (OCT) in enhanced-depth imaging (EDI) mode (EDI-OCT; sub-foveal ChT at 1000 µm, nasal ChT at 1000 µm temporal ChT). The CVI value (%) was calculated by dividing the luminal area by the sub-foveal total choroidal area. RESULTS: The mean sub-foveal ChT (297 ± 68 µm), nasal ChT (261 ± 66 µm), and temporal ChT (272 ± 68 µm) in eyes with OBD and the mean sub-foveal ChT (286 ± 31 µm), nasal ChT (266 ± 29 µm), and temporal ChT (269 ± 32 µm) in eyes with non-ocular BD were significantly decreased compared with those regions in healthy control subjects (333 ± 69, 301 ± 75, and 312 ± 70 µm, respectively). Additional subgroup analysis was performed for active OBD, inactive OBD, non-ocular BD, and the control group, and in pairwise comparisons, the CVI value was significantly decreased in both active (64.3 ± 3.1) and inactive OBD groups (64.2 ± 4.5) compared with healthy control subjects (67.2 ± 3.6; p = 0.026 and p < 0.001, respectively). There was no significant difference between non-ocular BD (65.9 ± 3.4) and control subjects (67.2 ± 3.6) for CVI measurements (p > 0.05). CONCLUSIONS: Decreased CVI values in OBD suggest that uveitis affects the choroidal vasculature and that perfusion is affected by uveitis, whereas systemic inflammation in non-ocular BD does not affect them. In addition, the choroid in uveitis is affected by the chronicity of the disease rather than disease activity. ChT measurements and CVI values may be a novel and robust prognosticating biomarker to evaluate choroidal vasculature and to monitor disease progression in OBD patients because EDI-OCT is a non-invasive imaging modality. However, CVI does not seem to be a biomarker for monitoring of disease activity or treatment efficacy.

A novel terminologic "naming-meshing" system using anterior chamber sedimentation for early diagnosis and prompt treatment of ocular or systemic diseases: is it hypopyon or pseudohypopyon?

A novel, algorithmic "naming-meshing" system was introduced for the distinction of hypopyon from pseudohypopyon to make an early diagnosis and prompt treatment of anterior chamber collection standardized to encompass all sediment characteristics. For this reason, a literature review of "hypopyon" and "pseudohypopyon" was conducted in MEDLINE/PubMed, Scopus, and Web of Science from 1966 to May 15, 2023. Two issues were clarified: 1) which strategies should the ophthalmologist follow when asked to evaluate an eye with anterior chamber sedimentation to distinguish hypopyon from pseudohypopyon, and 2) in which systemic disorders should a non-ophthalmologist order a prompt ophthalmic consultation to distinguish pseudohypopyon from hypopyon. Pathognomonic characteristics of the sediment were examined; scleral show (warm/cold), location (corneal/anterior chamber/capsular/posterior), visibility (macro/micro/occult-angle), orientation (horizontal/vertical/oblique), number (single/double), shape (convex/triangular/pyramidal/ring/lumpy/inverse), and color (white/yellow/pink/brown/black). Associated findings were then assessed; acute/chronic, spontaneous/provoked, unilateral/bilateral, inflammatory/non-inflammatory, suppurative (non-sterile)/non-suppurative (sterile), granulomatous/non-granulomatous, recurrent/non-recurrent, shifting/non-shifting, and transient/persistent. The type of precipitation was named (naming) and matched (meshing) to a potential list of etiologies (inflammatory, infective, therapeutic, masquerades). Given that (pseudo)hypopyon predominantly afflicts younger patients in their most productive years, clinicians supervising such patients should be aware of all sediment characteristics. The ophthalmologist should never ask non-ophthalmologists to run the full battery of tests in a patient with (pseudo)hypopyon, and rather indicate which type of collection is present, what its pathognomonic feature is, and what the most likely diagnoses to be excluded are.

Adalimumab rapidly controls both anterior and posterior inflammation in patients with ocular Behçet syndrome and non-infectious uveitis refractory to conventional therapy: a prospective, 6-month follow-up investigation.

PURPOSE: To evaluate the efficacy and safety of adalimumab (ADA, Humira®) for treatment of non-infectious uveitis (NIU) refractory to conventional medications. METHODS: Anti-tumor necrosis factor-α naive patients with NIU unresponsive to conventional immunosuppressive treatment were treated with ADA. Most cases with NIU were related to ocular Behçet syndrome. Adult cases used 80 mg ADA subcutaneously on day 0, 40 mg in the first week, and then 40 mg every 2-week, while this was 20 mg in children. Evaluations were performed pre-treatment and at weeks 2, 8, and 24. The study endpoints were best-corrected visual acuity (BCVA, LogMAR) improvement, anterior chamber (AC) cell grade, vitreous cell and haze grades, decrease in macular thickness and edema, prednisolone dose, immunosuppressive dose, and adverse reactions. RESULTS: Thirty-eight eyes (19 right, 19 left) of 24 patients (14 female, 10 male) with (ocular Behçet syndrome) OBS (n = 27 eyes/18 patients) and NIU (n = 11 eyes/6 patients) were included. Mean age was 29.0 ± 14.1 years (range, 5-49) and follow-up time was 24 weeks. After ADA, BCVA increased (p < 0.001), and improvements in AC cell grade (p < 0.001), vitreous cell grade (p < 0.001), and vitreal haze grade (p < 0.001) were achieved at the final visit. Mean macular thickness decreased from 243.5 to 235.5 µm (p < 0.001). Such a rapid control of both anterior and posterior uveitis was observed in all eyes as early as the second week without relapses during follow-up. No ocular or systemic complications emerged during treatment. CONCLUSIONS: ADA is effective and well-tolerated in pediatric and adolescent patients with NIU including OBS refractory to traditional medications and demonstrated corticosteroid- and immunosuppressive-sparing effects with no major side effects.

The Incidence of Optic Cracks or Fractures During a Foldable AcrySof or Acriva BB Acrylic Monofocal Intraocular Lens Implantation via the Manual Monarch Injector System With the Cartridge in Phacoemulsification Surgery.

PURPOSE: To evaluate the incidence of optic cracks and/or fractures during foldable acrylic intraocular lens (IOL) implantation via the manual Monarch delivery system with the cartridge and to determine factors that help to avoid such complications. METHODS: Small-incision phacoemulsification surgery was performed in 702 eyes with visually significant cataract formation. A foldable acrylic soft IOL (AcrySofâ MA60BM/MA30BA, Alcon, Fort Worth, TX, USA) or a single-piece acrylic soft IOL (Acriva BBâ, VSY Biotechnology, Amsterdam, The Netherlands) was inserted in all eyes using a cartridge and viscoelastic agents (sodium hyaluronate, Healon®, Advanced Medical Optics, Santa Ana, CA, USA). RESULTS: Postoperative central, paracentral, or peripheral optic cracks or fractures were encountered in a total of six of 702 eyes (0.85%). Four of six lenses (0.57%) had optic cracks within the IOL substance, whereas two of 702 cases (0.28%) had full-thickness IOL fractures in the substance in multiple locations. Three of the four lenses with optic cracks were noted to be handled by tying forceps during the cartridge insertion, and one of them was the complication of holding forceps. Two IOLs with full-thickness optic fractures were encountered during the insertion of the IOLs in the capsular bag as a result of direct trauma to the lens optic by the plunger of the injector system overriding the lens optic during cartridge passage. None of the patients suffered from glare or other visual disturbances postoperatively, and, therefore, none of the six eyes required lens replacement. CONCLUSION: The unintentional extensive pressure effect of the forceps during the holding process of the IOL or the direct trauma to the lens optic by the plunger of injector systems may cause optic cracks or fractures. Physicians should continue to monitor the eyes postoperatively regularly and must determine the benefits and risks to be derived from lens replacement, if such patients complain of significant glare, image degradation, and visual disturbances. We recommend the use of preloaded lenses, which have their own delivery systems and cartridges, to minimize the risk of such complications.

Comparison of the Rate of Posterior Capsule Opacification Following Combined Treatment With Topical Dexamethasone 0.1% Plus Ketorolac 0.5% Eye Drops Versus Dexamethasone 0.1% Alone: A Two-Year, Randomized Clinical Investigation.

Background and aim The use of non-steroidal anti-inflammatory drugs in animals decreases the incidence of posterior capsular opacification (PCO) following cataract surgery. We evaluated the rate of PCO in patients with cataract surgery and foldable "in the bag" posterior chamber intraocular lens (PC-IOL) implantation treated with combined dexamethasone 0.1% plus ketorolac tromethamine 0.5% versus dexamethasone 0.1% alone. Materials and methods A total of 114 eyes of 101 patients underwent uneventful corneal small-incision phacoemulsification with primary implantation of a foldable acrylic PC-IOL (AcrySof®, Alcon, Fort Worth, USA). Postoperatively for four weeks, group 1 eyes were treated with dexamethasone 0.1% plus ketorolac tromethamine 0.5% ophthalmic solutions four times daily for each whereas group 2 eyes were treated with dexamethasone 0.1% alone. Other regiments were the same for each group. Patients were evaluated between one- and four-year following surgery. The frequency and timing of severe PCO following surgery that needed Nd:YAG laser posterior capsulotomy were recorded and evaluated. Results The mean (SEM) age of group 1 (n = 54) and group 2 (n = 60) at operation was similar (62.8 ± 2.2 vs. 60.6 ± 1.7 years, respectively). Eighty-eight patients had unilateral cataract and 13 cases had bilateral disease. Overall, the mean follow-up duration was 24.7 months postoperatively (range, 15-48). Clinically significant PCO that finally needed Nd:YAG laser application developed in two eyes (3.7%) in group 1 and in four eyes (6.6%) in group 2, and the difference was not statistically significant (p>0.05). The mean month at capsulotomy was 26.5 in group 1 and 24.3 months in group 2 eyes (p>0.05). Conclusions Topical instillation of ketorolac ophthalmic solution in the immediate period after phacoemulsification and PC-IOL implantation did not seem to influence the incidence of PCO formation two years after cataract surgery.

Top 50 Most-Cited Publications on Blepharoplasty Surgery Between 2015 and 2022: From a Current Altmetric Perspective of Research Impact.

Background Blepharoplasty is one of the most-performed esthetic operations, and social media platforms have become an influential tool for distributing scientific information. Because the internet has gained popularity among medical experts and surgeons to connect with the public, we aimed to evaluate the altmetric-bibliometric analysis of the top 50 most-cited articles on blepharoplasty surgery between 2015 and 2022 and assess correlations with various metrics. Methods "Blepharoplasty" was searched using the WoS database, and the altmetric score was obtained. Co-authors, keywords, country of authors, and cited journal network map analysis were created using VOSviewer for the 485 publications retrieved. The articles' focus was examined quantitatively and the most prolific parameters were identified. Results The most research was performed by the USA, the most productive institution was the "University of California System," and the most prolific author was "Wonn CH." The number of citations ranged from 37 to 9, and altmetric attention scores ranged from 54 to 0. The most articles and citations peaked in 2021. Altmetric and Twitter scores were moderately correlated with journal metrics but there were no correlations with citation counts. Conclusion The first comprehensive altmetric analysis on blepharoplasty surgery offers new guidelines for upcoming articles by demonstrating the recent investigation trends, prolific parameters, and zones with potential for the public's attention and education, providing valuable data regarding the distribution of scientific knowledge in social media platforms and to the general public. A social network may be used to increase the visibility of scientific articles apart from creating brands and markets.

Success rate of external, endonasal, and transcanalicular laser DCR with or without silicone stent intubation for NLD obstruction: a network meta-analysis of randomized controlled trials.

PURPOSE: To define and compare the effectiveness of external dacryocystorhinostomy (EX-DCR), endonasal (EN-DCR), and transcanalicular laser-assisted (TL-DCR) with or without silicone stent (S) intubation. METHODS: Studies were retrieved from PubMed, Scopus, and WoS. Frequentist and Bayesian network meta-analyses were performed and pooled estimations were expressed as risk ratio (RR). We included all original investigations of prospective, randomized controlled trials comparing success rate for any two of the following six surgical procedures: standard EX-DCR with or without S, cold EN-DCR with or without S, and TL-DCR with or without S. The primary outcome measure was the objective success rate. RESULTS: Thirty-two studies with 3277 cases were included in the final quantitative analysis. TL-DCR with S was inferior to EN-DCR with S (RR: 1.20; 95% CI: 1.05-1.37), EX-DCR with S (RR: 1.17 95% CI: 1.05-1.29), EN-DCR without S (RR: 1.18; 95% CI: 1.03-1.35), and EX-DCR without S (RR: 1.15; 95%CI: 1.05-1.26) in frequentist statistics. No other statistical difference was found between other surgeries. When we excluded studies with additional interventions (nasal and revision surgery) for sensitivity analysis, 23 studies with 2468 cases were included to analysis. The success rates of TL-DCR with S and EN-DCR without S became similar (RR: 1.14 95% CI: 0.99-1.30) but there was no change in other outcomes. Similar results were found in Bayesian statistics. The surface under the cumulative ranking curve was higher for EN-DCR with S (0.75), whereas it was higher for EX-DCR with S (0.56) after sensitivity analysis. CONCLUSION: Between endoscopic and external and transcanalicular laser without S procedures, there is no statistical difference. The rank probability showed that EN-DCR with S was a more appropriate surgical option when patients with nasal disease were included, whereas EX-DCR with S was a more appropriate surgical option when patients with nasal disease were excluded from the analysis.

Modified external revision-DCR in previous failed endonasal, transcanalicular or external-DCR: technical strategy and teaching Pearls for success.

Objective: To report perioperative findings of patients with multiple failed-dacryocystorhinostomy (DCR) and to determine the success rate of revision external (rEx-DCR) performed by a modified technique. Methods: Thirty-one eyes of 31 patients (19 women, 12 men) with recurrent dacryocystitis or epiphora following at least one previous failed-DCR were assessed regarding the time from initial surgery to recurrence and revision surgery, type of primary surgery (endoscopic, transcanalicular, Ex-DCR), recurrence number, stent usage and the success rate. Relief of epiphora and positive dye test were established as functional and anatomical successes, respectively. Results: The mean age was 43.0 years (8-78), with a mean follow-up period of 21.4 months (6-46). The mean reoperation number was 1.4 (1-5). The mean time from initial surgery to recurrence was 15.2 months (1-55) and to rEx-DCR, 19.8 months (4-65). Untouched medial canthal ligament was observed in 28 (90.3%), improper rhinostomy location in 26 (83.8%), inadequate osteotomy size in 25 (80.6%), single-anterior-flap-only in 5 (16.1%), membranous ostial scar formation in four (12.5%) and no flap in three (9.6%) patients. The success rate was 93.5%, which was lower than our primary modified Ex-DCR (99.1%). Conclusions: The most common reasons for recurrence were small and unsuitable osteotomy locations with intact medial canthal ligaments. "Double-mucosal flap" approach with an anterior sacco-mucosal complex suspension increases the functional success rate, and stent implantation is not obligatory if canalicular problems or small/ atrophic sacs do not exist. The knowledge of technical strategy and teaching pearls improves the success rates of primary and revision surgeries. Abbreviations: DCR = dacryocystorhinostomy, Ex-DCR = external DCR, EE-DCR = endoscopic endonasal DCR, TC-LA-DCR = transcanalicular laser-assisted DCR.

One-step repair of a large congenital upper eyelid coloboma using a bilamellar graft in an infant: a case report and literature review.

Large congenital lid colobomas are traditionally repaired using 1- or 2-step vascularized flap-graft combinations. However, visual axis occlusion for weeks is a severe problem in small children and recent reports suggest that the flap pedicle does not contribute to blood perfusion. A "one-step" substitute for large lid defects has recently been reported in animals and humans, demonstrating the viability of a bilamellar autograft alone. We present an alternative "one-step" reconstructive approach in a 6-month-old infant who had a centrally-located large upper eyelid defect resulting from a congenital coloboma. The free full-thickness bilamellar autograft was harvested from the contralateral upper eyelid. The follow-up time was 48 months. Cosmetic and functional results were good, the bilamellar graft survived, and there was no graft ischemia, necrosis, or rejection. The boy developed madarosis, lid notching, and mild contour irregularity but needed no reoperation since the parent was satisfied with the surgical result. A free bilamellar eyelid autograft seems to be an outstanding alternative to both "conventional 2-step" and "modern 1-step" options for the reconstruction of large colobomatous eyelid openings, especially in young infants who cannot tolerate visual axis blockage. It is an easy, practical, fast, and effective technique that also saves cost in health care.

Top 50 most-cited articles on SMILE surgery between 2010 and 2022: a correlation comparison between conventional bibliometrics and current altmetrics of research impact.

PURPOSE: To conduct a bibliometric and altmetric analysis of the top 50 most-cited articles on small incision lenticule extraction (SMILE) surgery and assess its correlations with other metrics. METHODS: The terms "small incision lenticule extraction" or "SMILE" were searched in the title, abstract, and keywords using Web of Science database. The retrieved articles (n = 927, between 2010 and 2022) were analyzed in-depth using altmetric attention scores (AAS), and traditional metrics (citation numbers of articles, impact factor of journals, and other citation-based metrics). A correlation statistics was performed with metrics. The articles' focus was examined quantitatively and the most prolific parameters were identified. Authorship network and country statistics also was examined. RESULTS: Citation numbers were between 491 and 45. AASs were between 26 and 0. The altmetric score correlated moderately with citation number (r = 0.44, P = 0.001) and annual mean citations (r = 0.49, P < 0.001), but correlated weakly with impact factor (r = 0.28, P = 0.045), and immediacy index (r = 0.32, P = 0.022). The most articles published from China and the most articles were published in 2014. Modern SMILE surgery was mostly compared to the older LASIK procedure. The highest authorship number of links belonged to Zhou XT. CONCLUSION: The first bibliometric and altmetric analysis of SMILE research provides novel directions for future work by showing the current research trends, prolific parameters, and zones with potential for the public's attention, providing useful information about the dissemination of scientific knowledge on SMILE in social media and to the general public.

Macular optical coherence tomography angiography analysis in diabetes mellitus patients with a history of Covid-19.

PURPOSE: There is evidence of decreased vessel density in optical coherence tomography angiography (OCTA) after Covid-19. We aimed to investigate whether the outcome of retinal vasculopathy would be worse if patients with diabetes mellitus (DM) were infected with coronavirus using OCTA to assess retinal vessels. METHODS: One eye of each subject was included in the study. Diabetic patients without retinopathy and non-diabetic controls were divided into four groups according to their Covid-19 history: group 1=DM(-)Covid-19(-); group 2=DM(+)Covid-19(-); group 3=DM(-)Covid-19(+); and group 4=DM(+)Covid-19(+). All Covid-19 patients were not hospitalised. Macular OCTA scans were performed in a 6 × 6 mm area. RESULTS: Diabetes had no effect on the area of the foveal avascular zone (FAZ), but Covid-19 caused an increase in FAZ area. Diabetes and Covid-19 had an effect on both the superficial capillary plexus (SCP) and the deep capillary plexus (DCP) in the fovea. Eta squared (ƞ2) is a measure of effect size. The effect size of Covid-19 (ƞ2=0.180) was found to be greater than that of diabetes (ƞ2=0.158) on the SCP, whereas the effect size of diabetes (ƞ2=0.159) was found to be greater than that of Covid-19 (ƞ2=0.091) on the DCP. CONCLUSIONS: The percentage of vessel density was lower in the fovea and the FAZ area was enlarged in the diabetic patients who recovered from Covid-19. In diabetic patients Covid-19 may lead to deterioration of vascular metrics.
