RESUMO
BACKGROUND: Eyebrow tail ptosis is usually associated with dermatochalasis of the upper eyelid, and it is necessary to treat them together. For these associated procedures to be incorporated as a routine in upper eyelid surgeries, they should preferably be less invasive with consequent fewer complications. OBJECTIVE: We describe a minimally invasive technique for the correction of mild-to-moderate eyebrow tail ptosis corrected together with superior dermatochalasis through the blepharoplasty incision. METHODS: A phase 2 clinical trial was conducted from February 2020 to December 2021. A total of 50 patients underwent conventional upper blepharoplasty surgery associated with the proposed eyebrow lift technique: internal pexia in the periosteum, dissection, and posterior fixation of the orbicularis muscle to the arcus marginalis, removal of the lateral part of the orbicularis muscle, and loosening of the orbital retention ligament. Evaluation of the height of the eyebrow tail was performed with digital photography in the initial consultation and at 30-90 days postoperatively and analyzed with ImageJ software. RESULTS: Mean difference in brow height at 1-month and 3-month postoperative evaluations compared to the preoperative period was 3.45-3.33 mm, respectively. CONCLUSION: Our study demonstrated a minimally invasive surgical technique for the treatment of mild-to-moderate eyebrow ptosis with significant eyebrow tail lift results that remained stable during the study period.

PURPOSE: To develop an equation for estimating the vitreous chamber volume in pseudophakic patients based on the axial length of the eye. METHODS: A consecutive series of patients who underwent vitrectomy surgery for a macular hole or an epiretinal membrane were enrolled. The inclusion criteria were as follows: having pseudophakia, being older than 50 years, and having eyes with axial length ranging from 21 to 26 mm. Before the surgery, the axial length was measured using optical biometry. Pars plan vitrectomy was performed, and, after the fluid-air exchange, the vitreous chamber was filled with Brilliant Blue G (0.005%). The infused volume of each eye was recorded. Then, epiretinal membrane peeling or internal limiting membrane peeling and a new fluid-air exchange were performed. Main outcomes and measures were the vitreous chamber volume and axial length. RESULTS: The sample consisted of 112 patients. The mean [standard deviation (SD), range] age was 71 years (7, 53-90). Sixty-five individuals (58%) were women. In 58 (51.8%) patients, surgery was performed on the right eye. The mean (SD; range) axial length was 23.78 mm (0.93; 21.55-25.26), and the mean (SD; range) vitreous chamber volume was 4.96 mL (0.69; 3.60-6.40). Pearson's correlation coefficient (r = 0.950; p < 0.01) was positive, and the coefficient of determination (R2) was 0.902. The estimated regression equation was Y = 0.71X - 11.84, where Y was the vitreous chamber volume, X was the axial length of the eye, the linear coefficient for the straight line was - 11.83, and the angular coefficient was 0.71 (p < 0.01). CONCLUSION: These data suggest that the vitreous chamber volume is significantly correlated with the axial length and the former could probably be calculated using biometry. New studies with larger samples will be required to confirm these observations and will allow the development of an algorithm (perhaps non-linear) that includes extreme axial length values and that takes into account other factors such as the status of the lens and sex.

BACKGROUND: To investigate the effect of nicergoline on the rate of complete corneal ulcer reepithelialization (CCUR) in diabetic rats with diabetic keratopathy. METHODS: Forty-eight streptozotocin-induced diabetic rats were randomly divided into two groups. The experimental group (n = 24) received nicergoline (10 mg.kg- 1.day- 1), while the control group (n = 24) received a placebo. A corneal epithelial defect was induced using a corneal diamond burr, and defect area was compared at time points of 0, 12, 24, 48 and 72 h after the injury using image analysis software. The probability of CCUR within 72 h was assessed using the Kaplan-Meier survival analysis log-rank test. RESULTS: When compared, 4 of the 24 rats (17%) in the placebo group and 12 of the 24 rats (50%) in the nicergoline group were found to have CCUR within 72 h (log-rank = 0.027). Cox regression analysis found no effect of the covariates blood glucose (P = 0.601) or weight (P = 0.322) on the corneal reepithelialization (survival) curve. CONCLUSIONS: Nicergoline increased wound healing rates relative to placebo and may therefore be investigated as a treatment option in diabetic keratopathy.

PURPOSE: To compare the injection of small amounts of undiluted C3F8 with the traditional gas injection in vitrectomy for macular hole treatment. METHODS: This clinical trial included 26 individuals divided into two groups. Group 1 received an intravitreal injection of 0.9-1.0 mL of 100% C3F8, and Group 2 received 15-20 mL of 20% C3F8. RESULTS: The median intraocular gas duration was 31 days in Group 1 and 34 in Group 2. The median letter gains in corrected distance visual acuity for the 26th postoperative week were 20 letters in Group 1 and 12.5 in Group 2. The median intraocular pressure was normal in both groups. Primary anatomical success was 11/13 in both groups. CONCLUSIONS: The use of C3F8 gas in a small undiluted volume is an alternative that slightly reduces the duration of the gas without negatively affecting the anatomical and visual response.

HIV retinal microangiopathy is an important predictor for increased risk of mortality. Optical coherence tomography angiography (OCTA) can investigate microvascular changes resulting from retinal diseases. Study included 25 persons with HIV and 25 healthy persons. OCTA evaluated the vascularization of retinal layers, choriocapillary, and optic disk. HIV group had lower vessel flow density (VFD) in superficial plexus. No difference was observed in the deep plexus. VFD of the optic disk and peripapillary region showed no difference between the groups. HIV group showed a thinner retinal nerve fiber layer and smaller area of the optic disk rim. HIV infection is associated with VFD reduction in superficial retinal plexus, neural rim area reduction, and retinal nerve fiber layer thinning in individuals without microangiopathic alterations on fundus examination. Therefore, OCTA can find retinal changes before clinical evidence of retinopathy.
RESUMO
PURPOSE: This study aimed to describe the demographic and clinical characteristics of victims of fireworkrelated ocular trauma treated at the ophthalmologic emergency de partments of two reference centers in Pernambuco, Brazil, and to identify risk factors related to poor visual prognosis. METHODS: We retrospectively evaluated the medical records of patients admitted in emergency departments with a report of firework-related trauma between January 2012 and December 2018. Data collected included patient's age, sex, place of origin, month and year of the accident, ocular structures affected, characteristics of the injuries, and type of treatment that patients received. For patients who were followed for >30 days, the final visual acuity and patient's origin were analyzed. RESULTS: Three hundred and seventy eyes from 314 patients were included, of which 248 (79.0%) were male and 160 (51.0%) were from the metropolitan region of Recife. The mean patient age was 25.6 ± 18.8 years. In 56 (17.8%) patients, the ocular trauma was bilateral. A total of 152 (48.4%) cases occurred in June. The most affected sites were the eyelids in 91 (24.6%) eyes and ocular surface in 252 (68.1%). Surgical treatment was required in 87 (23.5%) eyes. After clinical and surgical management, 37 (10.0%) eyes presented final visual acuity of <20/400. Of these, 34 (91.9%) eyes were from patients from the countryside or from another state. Patients from the countryside presented higher risk of developing blindness after a firework trauma than those from the metropolitan area (odds ratio of 5.46). CONCLUSIONS: Victims of firework-related ocular trauma were mostly male, from the metropolitan region of Pernambuco state and mainly pediatric patients or economically active. Those coming from the countryside and other states had higher risk of developing blindness.

PURPOSE: To determine whether the axial length is associated with the education level in elderly patients with cataracts who were not exposed to electronic devices in the first two decades of life. METHODS: This cross-sectional study was conducted in elderly patients with cataracts in Campinas, Brazil. Patients were divided into 2 groups: Group 1 included those who completed, at most, elementary school (including the illiterate and those who partially or totally attended elementary school), which corresponded to 12 years of schooling; Group 2 included, at least, high school graduates (including those who completed high school and those who partially or fully attended university). The sample was selected randomly with stratification for sex and age. The main outcome was the axial length. RESULTS: The sample consisted of 472 elderly patients (236 per group) who underwent cataract surgery. There were 272 (57.6%) men and 200 (42.4%) women; the distribution was symmetrical between the two groups. The median age (IQR; range) was 66 (12; 50-89) years. The median axial length (IQR; range) was 22.82 (1.51; 20.34-28.71) mm in Group 1 and 23.32 (1.45; 20.51-31.34) mm in Group 2 (p<0.001). CONCLUSION: A greater axial length was associated with a higher level of education in elderly patients with cataracts, suggesting that myopization is related to an increase in activities requiring near-vision even before exposure to electronic devices.
RESUMO
Purpose: To compare the performance of nylon sutures to that of polyglactin sutures in pediatric patients undergoing cataract surgery. Setting: University of Campinas (UNICAMP), Campinas, São Paulo, Brazil Design: A prospective, randomized, partially masked, single-site clinical trial. (https://clinicaltrials.gov/ct2/show/NCT03812640). Methods: A total of 80 eyes from 80 patients who underwent pediatric cataract surgery were randomized into two groups in block sizes of four. Group A consisted of 41 patients whose surgical incisions were sutured with polyglactin 10-0 material. Group B consisted of 39 patients whose surgical incisions were sutured with nylon 10-0 material. The primary outcome was frequency of suture-related complications in each group. Secondary outcomes were the frequency with which suture removal was necessary. Results: The incidence of suture-related complications within 6 months of follow up was 0 out of 41 eyes (0.00%) in the polyglactin group and 17 out of 39 eyes (43.59%) in the nylon control group (p < 0.001). In all of the eyes with suture-related complications, the sutures were promptly removed. The most frequent complications were vascularization near the suture (17.95%) and loose sutures (17.95%). No ocular or systemic study-related adverse events were observed. Conclusions: Polyglactin sutures were found to be safe and effective for pediatric patients undergoing cataract surgery. Their lower rate of complications and reduced likelihood of removal (and the subsequent need for general anesthesia) make their use preferrable to that of nylon sutures. This study represents the first controlled randomized clinical trial to compare nylon sutures to polyglactin sutures in pediatric patients undergoing cataract surgery.

RESUMO
PURPOSE: To describe microvascular changes in the maculas of individuals with type 2 diabetes observed on optical coherence tomography angiography (OCTA) images. We compared the maculas of diabetic subjects without diabetic retinopathy with those of healthy subjects and correlated the findings with the clinical profiles of diabetic subjects. METHODS: One eye each of 30 patients with diabetes and 30 healthy individuals were examined. The patients with diabetes underwent funduscopy, retinography, and fluorescein angiography to rule out retinopathy. All subjects underwent optical coherence tomography angiography of a macular area (6×6 mm2), and the foveal and parafoveal vascular densities were analyzed in the superficial and deep retinal vascular plexus. The foveal and parafoveal thicknesses, foveal avascular zone of the superficial plexus, and choriocapillaris flow area were also examined. The optical coherence tomography angiography results were compared between the two study groups and correlated with the following parameters: visual acuity, time since diabetes diagnosis, glycemic control, lipid profile, and renal function of patients with diabetes. RESULTS: A minimal increase in the choriocapillaris flow area was observed in the patients with diabetes (mean area, 22.3 ± 4.6 mm2 in controls; 22.6 ± 3.9 mm2 in patients with diabetes) (p=0.017). No significant differences were observed between other optical coherence tomography angiography parameters analyzed in the two groups. Glycosylated hemoglobin and fasting blood glucose levels were significantly negatively correlated with the foveal vascular density of both plexuses; conversely, fasting blood glucose levels were positively correlated with the choriocapillaris flow area (p=0.034). The other clinical parameters were not correlated with the optical coherence tomography angiography findings. CONCLUSION: Optical coherence tomography angiography may not be the most appropriate tool for detecting preclinical changes in patients with diabetes, moreover, optical coherence tomography angiography; does not replace clinical examinations. Glycemic control should be the primary clinical parameter considered during retinopathy screening. Larger studies are necessary to confirm these findings.

PURPOSE: To investigate the association of the single-nucleotide polymorphism rs35934224 in the TXNRD2 gene with primary open-angle glaucoma in a Brazilian population. METHODS: This was a cross-sectional study conducted to verify the association between the rs35934224 TXNRD2 (thioredoxin reductase 2) and primary open-angle glaucoma in a population from the Northeast region of Brazil. A total of 184 individuals were enrolled, including 94 with primary open-angle glaucoma (45 men and 49 women) and 94 controls (40 men and 54 women) from the Recife Eye Institute. RESULTS: The mean age was 68.85 years for the patients with glaucoma and 68.55 years for the controls. Genomic DNA was isolated using commercially available kits, and single-nucleotide polymorphism was detected with real-time polymerase chain reaction using TaqMan probes. The studied population was in Hardy-Weinberg equilibrium. The CT genotype was associated with protection against primary open-angle glaucoma (p=0.022). CONCLUSION: Our data suggest an association between TXNRD2 gene polymorphism (rs35934224) with primary open-angle glaucoma in an admixed Brazilian po pulation. This is the first study to investigate this single-nucleo tide polymorphism in Latin American individuals with primary open-angle glaucoma.

Perfluorocarbon liquid has been widely used during vitreoretinal operations. Subretinal retention is a rare intraoperative complication, but even small quantities can damage the macular structure and function, and no standard treatment has been established. We encountered a 43-year-old woman who presented a retained subfoveal bubble after a vitreoretinal operation due to primary rhegmatogenous retinal detachment. Herein, we describe the procedure we used to remove the perfluorocarbon liquid without retinotomy using internal limiting membrane peeling.

PURPOSE: To evaluate vascular density in super-ficial and deep capillary plexuses of the retina, measured using optical coherence tomography angiography in patients with branch retinal vein occlusion. Affected eyes were compared with the contralateral eye of the same patient and both were compared with normal eyes. METHODS: A cross-sectional study including 16 previously untreated patients with branch retinal vein occlusion. Patients with poor quality examinations, bilateral disease, high refractive error, or any other retinal or choroidal disease were excluded. A total of 31 patients without eye disease were also selected as a comparison group. All participants underwent five optical coherence tomography angiographies, and only those with at least two good quality examinations were selected. The Kruskal-Wallis, Wilcoxon signed-rank, and Mann-Whitney U tests were used for the statistical analysis. RESULTS: Vascular density was lower in affected eyes compared with contralateral eyes: whole density (p=0.020 for capillary plexuses superficial; p=0.049 for deep capillary plexuses) and parafoveal density (p=0.020 for capillary plexuses superficial; p=0.011 for deep capillary plexuses). Vascular density was also lower in affected eyes compared with normal eyes: whole density (p<0.001 for capillary plexuses superficial and deep) and parafoveal density (p<0.001 for capillary plexuses superficial and deep). Whole density (p=0.001 for capillary plexuses superficial and deep) and parafoveal density (p=0.001 for capillary plexuses superficial; p<0.001 for deep capillary plexuses) were both lower in the contralateral eyes compared with normal eyes. Following adjustment for arterial hypertension, this difference was no longer observed. CONCLUSIONS: Vascular density in capillary plexuses and deep capillary plexuses was lower in the eyes affected by branch retinal vein occlusion. Furthermore, the lower vascular density noted in the contralateral eyes indicates that changes most likely occurred in these eyes prior to the appearance of any clinically detectable alterations, reflecting the early signs of hypertensive retinopathy.

ABSTRACT Purpose: To compare the injection of small amounts of undiluted C3F8 with the traditional gas injection in vitrectomy for macular hole treatment. Methods: This clinical trial included 26 individuals divided into two groups. Group 1 received an intravitreal injection of 0.9-1.0 mL of 100% C3F8, and Group 2 received 15-20 mL of 20% C3F8. Results: The median intraocular gas duration was 31 days in Group 1 and 34 in Group 2. The median letter gains in corrected distance visual acuity for the 26th postoperative week were 20 letters in Group 1 and 12.5 in Group 2. The median intraocular pressure was normal in both groups. Primary anatomical success was 11/13 in both groups. Conclusions: The use of C3F8 gas in a small undiluted volume is an alternative that slightly reduces the duration of the gas without negatively affecting the anatomical and visual response.
RESUMO
ABSTRACT Purpose: To compare the long-term ocular findings of children that were operated of congenital cataract before the age of two and that received an intraoperative intracameral triamcinolone injection or used postoperative oral prednisolone to modulate ocular inflammation. Methods: All patients who had previously participated in a clinical trial that analyzed the 1-year surgical outcomes of congenital cataract surgery utilizing intracameral triamcinolone (study group) or oral prednisolone (control group) were eligible to participate in this prospective cohort research. Patients' medical records were reviewed, and the children underwent a complete ophthalmologic exam on final follow-up. Biomicroscopic findings, intraocular pressure, central corneal thickness, the need for additional surgical interventions, and findings compatible with glaucoma were the primary end measures. Results: Twenty-six eyes (26 patients) were included (study group = 11 eyes; control group = 15 eyes). The mean follow--up was 8.2 ± 1.2 years and 8.1 ± 1.7 years in the study and control groups, respectively (p=0.82). All eyes presented a centered intraocular lens. There was no statistically significant difference between the groups with regards to the presence of posterior synechia (p=0.56), intraocular pressure (p=0.49), or central corneal thickness (p=0.21). None of the eyes fulfilled the glaucoma diagnostic criteria, presented secondary visual axis obscuration, or were reoperated. Conclusion: The long--term ocular findings of children that underwent congenital cataract surgery and received an intraoperative intracameral triamcinolone injection were similar to those that used postoperative oral prednisolone to modulate ocular inflammation. This suggests that intracameral triamcinolone may substitute oral prednisolone in congenital cataract surgery, facilitating the postoperative treatment regimen and compliance.
RESUMO Objetivo: Comparar os achados oculares em longo prazo de crianças que se submeteram à cirurgia de catarata congênita antes dos dois anos de idade e receberam uma injeção intracameral de triancinolona no intraoperatório ou usaram prednisolona oral no pós-operatório para modular a inflamação ocular. Métodos: Neste estudo prospectivo de coorte, todos os pacientes que participaram de um ensaio clínico anterior, que analisou os resultados cirúrgicos de 1 ano da cirurgia de catarata congênita usando triancinolona intracameral (Grupo de Estudo) ou prednisolona oral (Grupo Controle), eram elegíveis para participar. Os prontuários médicos dos pacientes foram revisados e as crianças foram submetidas a um exame oftalmológico completo no acompanhamento final. As principais medidas de desfecho foram: achados biomicroscópicos, pressão intraocular, espessura central da córnea, a necessidade de intervenções cirúrgicas adicionais e achados compatíveis com glaucoma. Resultados: Vinte e seis olhos (26 pacientes) foram incluídos (Grupo de Estudo = 11 olhos; Grupo de Controle = 15 olhos). O seguimento médio foi de 8,2 ± 1,2 anos e 8,1 ± 1,7 anos nos Grupos de Estudo e Controle, respectivamente (p=0,82). Todos os olhos apresentavam lente intraocular centrada. Não houve diferença estatisticamente significativa entre os grupos com relação à presença de sinéquia posterior (p=0,56), pressão intraocular (p=0,49) ou espessura central da córnea (p=0,21). Nenhum dos olhos preencheu os critérios diagnósticos para glaucoma, apresentou opacificação secundária do eixo visual ou foi reoperado. Conclusão: Os achados oculares em longo prazo de crianças que se submeteram à cirurgia de catarata congênita e receberam uma injeção intracameral de triancinolona no intraoperatório foram semelhantes aos que usaram prednisolona oral no pós-operatório para modular a inflamação ocular, sugerindo que a triancinolona intracameral pode substituir a prednisolona oral na cirurgia de catarata congênita, facilitando o tratamento pós-operatório e a adesão ao mesmo.

RESUMO Objetivos: Descrever as características demográficas e clínicas das vítimas de trauma ocular por fogos de artifício atendidas nas emergências oftalmológicas de dois centros de referência em Pernambuco e identificar fatores relacionados a mau prognóstico visual. Métodos: Avaliação retrospectiva dos prontuários de pacientes admitidos na emergência oftalmológica com história de trauma por fogos de artifício entre janeiro de 2012 e dezembro de 2018. A coleta de dados incluiu idade, gênero, procedência, mês e ano do acidente, estruturas oculares acometidas e características das lesões, além do tipo de tratamento a que os pacientes foram submetidos. Naqueles pacientes acompanhados por mais de 30 dias, analisou-se a acuidade visual final e a associação com sua procedência. Resultados: Foram incluídos 370 olhos de 314 pacientes. Destes, 248 (79,0%) vítimas eram do sexo masculino e 160 (51,0%) da região metropolitana do Recife, com uma média de idade de 25.6 ± 18.8 anos. Em 56 (17,8%) dos casos o trauma foi bilateral. No mês de junho ocorreu um total de 152 (48,4%) casos. Os sítios mais acometidos foram pálpebras em 91 (24,6%) olhos e superfície ocular em 252 (68,1%). O tratamento cirúrgico foi necessário em 87 (23,5%) olhos. Após manejo clínico-cirúrgico, 37 (10.0%) olhos desenvolveram visão pior do que 20/400. Destes, 34 (91,9%) olhos eram de pacientes do interior do estado de Pernambuco ou de outro estado. Os pacientes provenientes do interior do estado apresentaram maior chance de desenvolver cegueira quando comparados aos que eram provenientes da região metropolitana (Odds Ratio de 5,46). Conclusões: As vítimas de trauma ocular por fogos de artificio foram em sua maioria do sexo masculino, procedentes da região metropolitana do estado e das faixas etárias pediátrica e economicamente ativa. Aqueles provenientes do interior ou de outros estados apresentaram maior chance de desenvolver cegueira.
RESUMO
PURPOSE: To report the efficacy and safety of green laser photocoagulation for threshold retinopathy of prematurity (ROP). METHODS: We reviewed the clinical records of the neonates who had undergone green laser photocoagulation for threshold ROP at the Federal University of Pernambuco in Brazil between January 2004 and January 2006. All procedures were conducted with local anesthetic drops. The neonates were monitored throughout the procedure by a neonatologist. A frequency-doubled solid state laser, diode-pumped, with 532 nm wavelength was used. The presence of tunica vasculosa lentis or cataract were excluded before laser treatment. The following preoperative data were obtained for each patient: age, birth weight and the grade of ROP. Postoperative data included complications associated with the laser treatment, grade of ROP and evaluation whether further surgery was necessary due to failure of laser photocoagulation. RESULTS: Twenty-two neonates underwent photocoagulation with green laser for threshold ROP. A total of 31 eyes were included in the study. The mean gestational age was 30 +/- 3 weeks and the mean birth weight was 1120 +/- 490 g. Regression of the disease after laser therapy was observed in 30 eyes (96.7%). Despite treatment one eye presented stage 4A. Only 7 eyes required repetitive laser therapy. No adverse effects such as burning anterior segment tissues or bleeding in the anterior chamber occurred. No posterior segment side-effects were observed. Cataract formation was not observed at the last follow-up examination. CONCLUSIONS: Green laser photocoagulation remains an effective and safe alternative to red laser photocoagulation and to cryotherapy in the treatment of threshold ROP.

PURPOSE: To identify the frequency of ocular diseases among recipients of disability benefits in the metropolitan region of Recife, Brazil. METHODS: A review was performed of 217,221 cases of disability benefits granted between 2010 and 2015 by the executive managerial department of the Brazilian National Institute of Social Security (Instituto Nacional do Seguro Social [INSS]) in Recife, which encompasses 14 municipalities of the metropolitan region, including the capital. The frequencies of the identified cases of ocular morbidity were then determined according to their group in the International Classification of Diseases, 10th Revision (ICD-10), their cause, the age, sex, and income of the recipient, and the type and duration of the benefit. RESULTS: Of all disability benefits granted, 5,324 (2.5%) were due to ocular disease, the majority (91.1%) consisting of sick pay. Most of the beneficiaries (64.6%) were males, were 20 to 59 years of age, and 61.2% earned the minimum wage or less. The principal ocular diseases for which sick pay benefits were granted were cataract (24.5%), conjunctivitis (21.1%), and pterygium (8.8%). Blindness and low vision were the principal ocular diseases in cases of accident indemnity and disability retirement. CONCLUSIONS: The results highlight the magnitude of the problem of ocular diseases to the social security system, with serious economic and social losses, and emphasize the need for measures aimed at their prevention. Moreover, integration between the national departments of health and social security needs to be improved.

OBJECTIVE: To study the safety parameters associated with intracameral moxifloxacin application five weeks after cataract surgery. METHODS: The study was a prospective case series set in a private hospital in Recife, Pernambuco, Brazil. A consecutive sample of 1,016 cataract surgeries was evaluated. The inclusion criteria were patients with indications for cataract surgery, a minimum of 55 years of age, and no history of allergy to quinolones. Patients were prepared for surgery using a 5% povidone solution diluted as a topical antiseptic agent. The operative technique was phacoemulsification with intraocular lens implantation. A 0.3-mL syringe was partially filled with moxifloxacin and 150 µg/0.03 mL of moxifloxacin was administered through the surgical incision at the end of the surgery. Postoperatively, patients were prescribed: (1) 0.5% moxifloxacin eyedrops 5 times daily for 1 week, and (2) 1% prednisolone acetate eyedrops 5 times daily for 1 week, followed by 4 times daily for 1 week and, subsequently, 2 times daily for 3 weeks. The outcomes were incidence of acute endophthalmitis, mean changes from baseline to 5 postoperative weeks in corneal endothelial cell density, corrected distance visual acuity and intraocular pressure. RESULTS: The mean age was 67 ± 5 years, and 56.2% of the patients were female. There were no cases of endophthalmitis. The mean preoperative corrected distance visual acuity was 58 letters ± 10 (SD), and the mean postoperative corrected distance visual acuity was 80 letters ± 4 (SD). The mean change in corneal endothelial cell density was 249 cells/mm (-10.3%). There was almost no difference in intraocular pressure. No study-related adverse events were observed. CONCLUSION: The results suggest moxifloxacin is a safe option for intracameral use after cataract surgery.

ABSTRACT Purpose: To determine whether the axial length is associated with the education level in elderly patients with cataracts who were not exposed to electronic devices in the first two decades of life. Methods: This cross-sectional study was conducted in elderly patients with cataracts in Campinas, Brazil. Patients were divided into 2 groups: Group 1 included those who completed, at most, elementary school (including the illiterate and those who partially or totally attended elementary school), which corresponded to 12 years of schooling; Group 2 included, at least, high school graduates (including those who completed high school and those who partially or fully attended university). The sample was selected randomly with stratification for sex and age. The main outcome was the axial length. Results: The sample consisted of 472 elderly patients (236 per group) who underwent cataract surgery. There were 272 (57.6%) men and 200 (42.4%) women; the distribution was symmetrical between the two groups. The median age (IQR; range) was 66 (12; 50-89) years. The median axial length (IQR; range) was 22.82 (1.51; 20.34-28.71) mm in Group 1 and 23.32 (1.45; 20.51-31.34) mm in Group 2 (p<0.001). Conclusion: A greater axial length was associated with a higher level of education in elderly patients with cataracts, suggesting that myopization is related to an increase in activities requiring near-vision even before exposure to electronic devices.
RESUMO Objetivo: Determinar se o diâmetro axial está associado ao nível educacional em pacientes idosos com catarata que não foram expostos a dispositivos eletrônicos nas duas primeiras décadas de vida. Métodos: Este estudo transversal foi conduzido em pacientes idosos com catarata na cidade de Campinas, Brasil. Os Pacientes foram divididos em 2 grupos: no Grupo 1 foram incluídos aqueles que completaram, pelo menos, o ensino fundamental (incluindo analfabetos e aqueles com ensino fundamental completo ou incompleto), o que corresponde a 12 anos de escolaridade; no Grupo 2 foram incluídos indivíduos que, pelo menos, estudaram até o ensino médio (incluindo indivíduos com ensino médio completo e superior completo ou superior incompleto). A amostra foi selecionada aleatoriamente com estratificação por sexo e idade. O desfecho principal foi a medida do diâmetro axial. Resultados: A amostra foi constituída por 472 indivíduos que foram submetidos a cirurgia de catarata. Duzentos e trinta e seis indivíduos (50%) foram alocados no Grupo 1 e duzentos e trinta e seis indivíduos (50%) no Grupo 2. A mediana da idade (IIQ; intervalo) foi 66 (12; 50-89) anos. Duzentos e setenta e dois (57,6%) eram homens e duzentos (42,4%) mulheres, com distribuição simétrica entre os dois grupos. A mediana do diâmetro axial (IIQ; intervalo) foi 22,82 (1,51; 20,34-28,71) mm no Grupo 1 e 23,32 (1,45; 20,51-31,34) mm no Grupo 2 (p<0,001). Conclusão: Maiores medidas de diâmetro axial foram associadas a níveis educacionais mais elevados em pacientes idosos submetidos a cirurgia de catarata. Tal achado sugere que a miopização relacionada ao aumento de atividades que utilizam a visão de perto é fenômeno que ocorre antes mesmo da exposição a dispositivos eletrônicos.
RESUMO
PURPOSE: To determine the release profile of moxifloxacin encapsulated in liposomes in the aqueous humor as a controlled release system for intracameral application. METHODS: Liposomes containing moxifloxacin were obtained using the lipid film hydration method and were characterized by particle size and encapsulation efficiency. Female rabbits were used for the in vivo profile release study. Liposomes containing moxifloxacin was injected into the anterior chamber of the right eye of each animal. The rabbits were divided into five groups, and a sample of aqueous humor was collected 2, 4, 8, 24, and 48 h after administration of liposomes containing moxifloxacin administration. Moxifloxacin concentrations in the aqueous humor were analyzed using high-performance liquid chromatography. RESULTS: The average size of the liposomes containing moxifloxacin was 60.5 ± 0.72 nm with a particle size distribution of 0.307. The encapsulation efficiency of moxifloxacin in liposomes was 92.24 ± 0.24%. The results of an in vivo release study of liposomes containing moxifloxacin, showed that the maximum moxifloxacin concentration was achieved within the first 2 h after administration (5.27 ± 1.09 mg/mL) and was followed by a decrease in intracameral concentration (0.35 ± 0.05 mg/mL) until the 24 h mark. CONCLUSIONS: The in vivo experiments resulted in liposomes containing moxifloxacin that were homogenous in size and exhibited high drug encapsulation efficiency. The results indicate that liposomes containing moxifloxacin offers a satisfactory aqueous humor release profile after intracameral application.
