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.

Purpose: To evaluate outcomes of resident-performed cataract surgeries in different training levels in a retrospective case series. Patients and Methods: A total of 730 surgeries performed by residents were evaluated into three groups: surgeries performed during residents' first semester of training in phacoemulsification (Level 1 – L1), surgeries performed during the second semester (Level 2 – L2), and surgeries performed during the third semester (Level 3 – L3). The primary outcome was the incidence of intraoperative complications in each group. Secondary outcomes were the comparisons between initial and final corrected distance visual acuity (CDVA), intraocular pressure (IOP), endothelial cell density (ECD), and central corneal thickness (CCT) in each group. Descriptive statistical analyses were employed in the presentation of the results using central tendency and variance measurements. Results: The rate of complications within six weeks of follow-up was 24 out of 102 eyes (23.53%) in the L1 group, 63 out of 301 eyes (20.93%) in the L2 group, and 37 out of 327 (11.31%) in the L3 group (p=0.001). Posterior capsule rupture (PCR) was the most frequent intercurrence observed in all three semesters: it occurred in 12.7% of the surgeries in the first semester (13/102), 16.9% of surgeries in the second semester (51/301), and 9.5% of surgeries in the third semester (31/327). There was no significant difference in CDVA (p=0.298), ECD (p=0.067), IOP (p=0.217), or CCT (p=0.807) between the groups. Conclusion: When measured by rates of complications and by the aforementioned parameters, surgical competency was found to improve as surgical experience and frequency increased. Therefore, this study identified some patterns of skill development that can be applied to teaching strategies and better assist surgeons in training. [ABSTRACT FROM AUTHOR]

The purpose of this study was to measure the extent to which complications relating to cataract surgery are a cause of visual impairment in a population aged 50 and over from the city of Campinas, São Paulo State, Brazil. An assessment of cataract surgery services was conducted using random cluster sampling, with the sample composed of 60 clusters of 40 people aged 50 years or older. Of the selected sample of 2,400 subjects, 92.67% were examined. Of these 2,224 examined subjects, 75 (3.37%) presented bilateral visual impairment and 164 unilateral, while a total of 314 (7.06%) eyes presented visual impairment. 352 eyes had undergone cataract surgery. The causes of visual impairment after surgery were concurrent eye disease (56%), surgical complications (28.8%) and refractive errors (15.2%). Cataract surgery complications represented the 5th most important cause of visual impairment. The other main causes were cataract, posterior segment disorders, diabetic retinopathy and glaucoma. These results suggest cataract surgery complications are a major cause of visual impairment in this population. Their prevention and treatment must be part of public health care policies. Objetivou-se avaliar a relevância das complicações de facectomias como causa de baixa acuidade visual na população > 50 anos em Campinas, São Paulo, Brasil. Uma avaliação dos serviços de cirurgia de catarata foi conduzida utilizando amostragem aleatória de agrupamentos populacionais, sendo composta por 60 agrupamentos de 40 pessoas > 50 anos. Na amostra de 2.400 indivíduos, 92,67% foram examinados. Dos 2.224 examinados, 75 (3,37%) apresentaram baixa acuidade visual bilateral, 164, unilateral. e um total de 314 (7,06%) olhos apresentou baixa acuidade visual. Trezentos e cinqüenta e dois olhos tinham sido submetidos a facectomias. As causas de baixa acuidade visual pós-cirurgia foram doenças oculares concomitantes (56%), complicações cirúrgicas (28,8%) e erros refrativos (15,2%). Complicações de cirurgias de catarata foram a quinta causa mais importante de baixa acuidade visual. Outras causas principais foram catarata, doenças oculares do segmento posterior, retinopatia diabética e glaucoma. Estes resultados sugerem que complicações de cirurgias de catarata é uma importante causa de baixa acuidade visual na população em estudo. Sua prevenção e tratamento precisam fazer parte das políticas de saúde pública.

Incidence of preoperative rise in blood pressure (BP) in cataract surgery among hypertensive and normotensive patients. Objective: To study the incidence of preoperative rise in BP in cataract surgery among normotensive individuals and hypertensive patients with historic good BP control in a population without other major chronic diseases. Settings: Ophthalmology Service of a University Hospital. Materials and Methods: A prospective study with 822 patients older than 40 years of age, with cataract surgery indication, and without major chronic diseases other than hypertension. The patients were divided in two groups: hypertensive and normotensive. Preoperative data, physical exams and medical adverse events were recorded in an evaluation questionnaire. Results: The sample included 427 normotensive (52%) and 395 hypertensive patients (48%). The two groups had similar proportions of operations that were cancelled and not subsequently rescheduled, 2% (eight patients) in each group. The incidence of preoperative rise in BP was 3.7% in the normotensive group and 10.9% in the hypertensive group (P < 0.001). Conclusion: Hypertensive patients with historic good BP control and without other major co-morbidities present a larger incidence of preoperative rise in BP than normotensive individuals in cataract surgery.

Orientadores: Rodrigo Pessoa Cavalcanti Lira, Carlos Eduardo Leite Arieta Dissertação (mestrado) - Universidade Estadual de Campinas, Faculdade de Ciências Médicas Resumo: Introdução: Os Antiinflamatórios tópicos são utilizados comumente no tratamento da inflamação ocular e do edema macular cistóide relacionado a cirurgia de catarata. Tem sido sugerido o uso de antiinflamatórios antes da cirurgia, para conseguir uma melhor midriase intraoperatória. Foi relatado que quando midriase e maior do que 6 mm, a incidência de ruptura da cápsula posterior e reduzido pela metade. O objetivo deste estudo original foi comparar o efeito do uso pré-operatório do acetato de prednisolona, do cetorolaco de trometamina, do nepafenaco e de um placebo, na manutenção da midriase intra-operatória da cirurgia de catarata. Objetivo: Comparar o efeito do uso pré-operatório dos antiinflamatórios tópicos acetato de prednisolona 1%, nepafenaco 0.1% e cetorolaco de trometamina 0.4%, alem de um placebo, na manutenção da midriase intraoperatoria durante a cirurgia de catarata. Desenho: Ensaio clinico aleatorizado, mascarado, realizado em um único centro. Métodos: E um estudo composto por 140 pacientes submetidos a cirurgia de facoemulsificação de catarata. Os pacientes (35 voluntários por grupo) foram aleatorizados para receber o placebo (carboximetilcelulose de sódio 0,5%), acetato de prednisolona 1%, cetorolaco de trometamina 0,4% e o nepafenaco 0,1%. Os colírios eram administrados 3 vezes ao dia e iniciados 48 horas antes da cirurgia.. A medida do tamanho da pupila foi realizada pelo cirurgião usando um compasso nos seguintes momentos: antes da secção da córnea e ao final da cirurgia. O desfecho primário foi avaliar a eficácia de cada medicamento em inibir a miose intraoperatoria (pupilas > 6mm, no final da cirurgia). O desfecho secundário foi obter pupilas > 6mm no inicio da cirurgia. Resultados: O numero de pacientes no grupo da prednisolona (29/35), no grupo do nepafenaco (31/35) e no grupo do cetorolaco (30/35) com diâmetro pupilar > 6 mm foi maior do que no grupo placebo em relação a manutenção da midriase intraoperatoria (19/35 - P =. 003). Não houve diferença estatística entre o grupo da prednisolona, do nepafenaco e do cetorolaco na manutenção da midriase intraoperatória (P =. 791). Não houve complicações durante a cirurgia ou efeitos adversos relacionados com o uso pré-operatório do colírio. Conclusão: O uso pré-operatório da prednisolona, do cetorolaco e do nepafenaco foi eficaz na manutenção midriase intraoperatória quando comparado com o placebo Abstract: Introduction: Topical anti-inflammatory drugs are commonly used in the management of ocular inflammation and cystoid macular edema related to cataract surgery. It has been suggested the use of anti-inflammatory drugs before surgery, to achieve better intraoperative mydriasis. It was reported that, when mydriasis is greater than 6 mm, the incidence of posterior capsule rupture is reduced by half. The objective of the original study was to compare the effect of preoperative use of topical anti-inflammatory prednisolone acetate, ketorolac tromethamine, nepafenac and placebo, in the maintenance of intraoperative mydriasis in cataract surgery. Purpose: To compare the effects of preoperative use of topical anti-inflammatory prednisolone acetate, ketorolac tromethamine, nepafenac and placebo, on the maintenance of intraoperative mydriasis during cataract surgery. Design: Randomized clinical trial, single-center and masked. Methods: This study comprised 140 patients scheduled for cataract surgery. Patients (35 in each group) were randomized to receive placebo, prednisolone acetate, ketorolac tromethamine 0.4 % or nepafenac. These eye drops were administered three times daily for the two days prior to surgery. The pupillary diameters were measured by the surgeon using a compass prior to the corneal section and at the end of surgery. The primary outcome was the number of patients with pupil > 6 mm at the end of the surgery; the secondary outcome was the number of patients with pupil > 6 mm at the beginning of the surgery. Results: All the patients achieved pupil > 6 mm at the beginning of the surgery. The number of patients in the prednisolone (29/35), nepafenac (31/35) and ketorolac (30/35) groups with pupil > 6 mm was greater than in the placebo group in the maintenance of intraoperative mydriasis (19/35 - P =.003 - Table 2). There was no statistical difference among the prednisolone, nepafenac and ketorolac groups in the maintenance of intraoperative mydriasis (P =.791). There were no complications during surgery or related to the preoperative use of the eye drops. Conclusion: Preoperative use of ketorolac, prednisolone and nepafenac was effective in maintaining intraoperative mydriasis when compared with placebo Mestrado Oftalmologia Mestre em Ciências Médicas
