RESUMO

Objective In this study, we aimed to evaluate the choroidal thickness in patients with unilateral strabismic amblyopia by using spectral domain-enhanced depth imaging-optical coherence tomography (SD-EDI-OCT) (Heidelberg Engineering GmbH, Heidelberg, Germany). Methods Twenty-five children with strabismic amblyopia and 20 age- and sex-matched healthy controls were included in this study. Seven sections were obtained, each comprising 25 repetitive images from each section at 200-micron intervals, and measurements were taken from nine different points at vertical and horizontal lines (1 and 3 mm from the subfoveal, superior, inferior, temporal, and nasal regions), centered on the fovea, using SD-EDI-OCT. Choroidal thickness values were obtained by measuring the distance between the basal border of the retinal pigment epithelium and the choroidoscleral border. The Mann-Whitney U test was used to compare choroidal thickness between the amblyopic and the control groups. Results The mean age of children with amblyopia and that of controls were 8.4 ±2.7 and 9.9 ±3.3 years, respectively (p=0.120). The mean subfoveal choroidal thickness was 372.8 ±78.9 µm in amblyopic eyes and 372.4 ±79.3 µm in the fellow eyes, both of which were thicker than the control eyes (310.9 ±76.3 µm; p<0.05 for each). Similarly, the mean values for the choroidal thickness of the amblyopic children at 1 mm nasal (320 ±86 µm), 1 mm superior (363 ±70 µm), and 3 mm superior (336 ±62 µm) were also significantly thicker than those of the corresponding control eyes (p<0.05 for each). There was a negative correlation between the subfoveal choroidal thickness and axial length (r=-0.332, p=0.005). There were no correlations between the choroidal thickness, age, and visual acuity. Conclusions The choroidal thicknesses of strabismic and fellow eyes were similar in patients with strabismic amblyopia. However, the choroidal thickness of both eyes in strabismic children was significantly thicker than those of the healthy controls. Emmetropization may be defective in both eyes of strabismic amblyopic patients.

RESUMO

PURPOSE: Behçet's disease (BD) is an autoimmune chronic systemic inflammatory disease characterized by a versatile clinical spectrum. Growth arrest specific protein 6 (GAS6)/soluble AXL (sAXL) signaling pathway draws attention in the resolution of inflammation, and its deficiency is associated with chronic inflammatory, autoimmune diseases, as well as clearance of apoptotic cells by phagocytes - efferocytosis. In this study, it was aimed to investigate whether GAS6/sAXL, interleukin (IL)-10, nitric oxide (NO), and BCL-2 levels were associated with inflammation and efferocytosis contributes to the pathogenesis of BD. METHODS: A total of 37 Behçet patients with ocular involvement and 30 healthy control subjects were included in this study. GAS6, sAXL, IL-10, NO, and BCL-2 levels were quantified using enzyme-linked immunosorbent assay (ELISA) method. RESULTS: Serum GAS6, sAXL, IL-10, NO, and BCL-2 levels were significantly lower in patients with BD compared to the controls (P < 0.005, P < 0.001, P < 0.001, P < 0.001, and P < 0.001, respectively). In correlation analysis, research parameters decreased in patients with BD was significantly correlated with each other: GAS6-IL-10 (r = 0.585, P < 0.001), GAS6-BCL-2 (r = 0.541, P < 0.001), sAXL-BCL-2 (r = 0.696, P < 0.001), IL-10-NO (r = 0.717, P < 0.001), IL-10-BCL-2 (r = 0.759, P < 0.001), and NO-BCL-2 (r = 0.541, P < 0.001). CONCLUSION: In conclusion, decreased serum BCL-2 level may be an indicator of increased apoptosis in these patients and decreased levels of GAS6/sAXL, IL-10, and NO may indicate insufficient clearance of apoptotic bodies released as a result of increased apoptosis in BD patients.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

OBJECTIVE: To evaluate optic nerve head changes in patients with thyroid orbitopathy (TO) and investigate the effects of intravenous methylprednisolone (IV MTP) on these changes. METHODS: Eighty-two eyes of 41 patients with TO with and without dysthyroid optic neuropathy (DON) and 40 eyes of 40 healthy control subjects were included in the study. Lamina cribrosa thickness (LCT) and depth (LCD) measurements, peripapillary retinal nerve fibre layer thickness (RNFLT), and radial peripapillary capillary vascular density were measured using optical coherence tomography and optical coherence tomography angiography. Visual field examination and proptosis were evaluated. Patients with DON and active non-DON received IV MTP for 12 weeks, and the effect of this treatment was evaluated. RESULTS: Peripapillary vascular density decreased in patients with DON compared with the other groups (p < 0.001 for all); there was no difference in the total, superior hemi-sector, and inferior hemi-sector of the RNFLT between the groups. LCT was decreased in the TO group (p < 0.001). After IV MTP treatment, the LCT and best-corrected visual acuity were increased. Thyroid-stimulating hormone receptor antibody levels, intraocular pressure, the superior hemi-sector of the RNFLT, and proptosis were decreased compared with the control subjects (p = 0.012, p = 0.008, p = 0.043, and p < 0.001, respectively). CONCLUSIONS: The RNFLT may not always increase in DON. Lamina cribrosa morphology may change in patients with TO. IV MTP therapy has a positive effect on the LCT but not on radial peripapillary capillary vascular density or LCD.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

Purpose: To report our initial experience in patients with primary pterygium surgery who had a transparent intrastromal corneal lenticule as a free graft obtained during small incision lenticule extraction (SMILE) surgery. Observations: This study enrolled five eyes of 5 patients with pterygium who were surgically treated with single or double free lenticule that was sutured to the defective area of the nasal corneosclera immediately following pterygium excision. All cases with pterygium were primary, and topical mitomycin C was not used at the time of surgery. The mean age of the patients was 51.0 years and 2 of the 5 eyes belonged to male subjects. The patients were followed up for an average of six months. During the follow-up period, the lenticule grafts demonstrated no sign of rejection and were intact in all cases. All patients recovered well with no complications or recurrences at six months postoperatively. Conclusions and Importance: This report suggests that transparent corneal lenticules obtained during SMILE laser surgery may be used as an alternative novel graft source for the surgical treatment of patients with primary pterygium. It appears to be a safe, easy, cost- and time-effective reliable method.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.
