Laceração de canalículo lacrimal em centro de referência do centro-oeste paulista / Lacrimal canaliculus laceration in a reference center in the Center-West of the state of São Paulo

RESUMO Objetivo: Descrever as características clínico-epidemiológicas, técnicas cirúrgicas e resultado do tratamento das lacerações canaliculares operadas em nosso serviço. Métodos: Estudo retrospectivo, realizado de janeiro de 2012 a junho de 2020, considerando-se as lesões de canalículo lacrimal operadas em um serviço de referência. Dados demográficos, características das lesões, detalhes das cirurgias e resultado do tratamento foram obtidos de prontuários eletrônicos e analisados estatisticamente. Resultados: Foram incluídos 26 portadores de lesões canaliculares, com idade entre 2 e 71 anos, sendo 73,1% homens. A lesão acometia o canalículo superior em 53,9%; 80,8% pacientes procuraram pelo serviço nas primeiras 24 horas, e 46,2% tiveram a cirurgia realizada entre 24 e 72 horas após o traumatismo. Todos os pacientes tiveram intubação mono ou bicanalicular, e o tempo transcorrido entre a cirurgia e a retirada do silicone, variou de zero a 183 dias. Após a cirurgia, 21 pacientes (80,8%; p<0,05) não apresentaram complicações, 2 (7,7%) evoluíram com obstrução canalicular, 2 (7,7%) com granuloma e 1 (3,8%) com ectrópio de ponto lacrimal. Conclusão: As lesões de canalículo encontradas em nossa prática são mais comuns em crianças ou homens jovens, acometem mais o canalículo superior e as nossas condutas levam a sucesso no tratamento na maior parte dos casos. As grandes controvérsias no assunto persistem, como o tipo e o tempo de permanência do tubo de silicone na via lacrimal. Somente estudos com grandes amostras podem consolidar esses conceitos.

ABSTRACT Objective: To describe the clinical and epidemiological characteristics, surgical techniques, and results of the canalicular laceration treatment at our service. Methods: A retrospective study was carried out from January 2012 to June 2020, considering canalicular injuries operated at a reference center. Demographic data, lesion characteristics, surgical details, and treatment outcomes were obtained from electronic medical records and were statistically analyzed. Results: Twenty-six cases of people with canalicular lesions aged between 2 to 71 years old were included, of whom 73.1% were men. The superior canaliculus was affected in 53.9%; 80.8% of patients searched for care within the first 24 hours, and 46.2% had the surgery performed between 24-72 hours after trauma. All patients had mono or bicanalicular intubation and the time elapsed between surgery and silicone removal ranged from 0 to 183 days. After surgery, 21 patients (80.8%, p<0.05) did not present any complications, two (7.7%) evolved with canalicular obstruction, two (7.7%) with granuloma, and one (3.8 %) with lacrimal puncta ectropion. Conclusion: In our practice, canalicular injuries are more common in children or young men, affecting mainly the superior canaliculus, and treatment success using our approach can be achieved in most of the cases. However, great controversies remain on the subject, such as type of intubation and when to remove the silicone tube from the lacrimal pathway. Larger series are required to consolidate controversial concepts.

Amniotic membrane transplantation in ocular surface diseases / Transplante de membrana amniótica em doenças da superfície ocular

Abstract Objective: To evaluate the clinical effectiveness of amniotic membrane transplantation for ocular surface reconstruction. Methods: Prospective study including 23 eyes of 21 patients who underwent amniotic membrane transplantation at Hospital de Clínicas da Universidade Federal do Paraná (HC-UFPR) and at Cirurgia e Diagnose em Oftalmologia do Paraná (CDOP) clinic, located in Curitiba, PR, Brazil, from may 2015 to july 2019. The amniotic membrane was collected from elective and term cesarean delivery, and conserved in preservation medium and glycerol 1:1, stored at -80° Celsius. The membrane was fixed on the ocular surface with 10-0 nylon, 8-0 vicryl, biological glue or a combination of these materials. Results: The ocular surface reconstruction was successful in 22 eyes (95.6%). Failure was observed only in 1 case (bullous keratopathy) in which the condition was maintained postoperatively. Patients' age ranged from 11-82 years, with a mean age of 37.4 years. There was a higher incidence in males (66.6%). A difference was perceived in the distribution of the affected eye (which was greater in the right eye - 65.2%). As for the previous ophthalmic surgery history, 12 of the 23 eyes had a positive history (52.2%). It was observed that all patients who had preoperative visual acuity assessed showed improvement or maintenance of corrected visual acuity. In the postoperative period, complications associated with the underlying disease were observed, although not particularly related to the amniotic membrane transplantation. There were not any cases of postoperative infection. Conclusions: There was an improvement in the general state of the ocular surface in almost all of the cases in which the transplant was performed. Therefore, the amniotic membrane can be considered a good alternative for reconstructing the ocular surface, as a single or supporting treatment.

Resumo Objetivo: Avaliar a eficácia clínica do transplante de membrana amniótica na reconstrução da superfície ocular. Métodos: Estudo prospectivo incluiu 23 olhos de 21 pacientes que realizaram transplante de membrana amniótica no Hospital de Clínicas da Universidade Federal do Paraná (UFPR) e na clínica de Cirurgia e Diagnose em Oftalmologia do Paraná (CDOP), localizados em Curitiba, PR, Brasil, no período de maio de 2015 a julho de 2019. A membrana amniótica foi captada a partir de parto cesárea eletivo e a termo, conservada em meio de preservação e glicerol 1:1 e armazenada a -80° Celsius. A membrana foi fixada na superfície ocular com fio nylon 10-0 ou vicryl 8-0 e/ou cola biológica. Resultados: A idade dos pacientes variou de 11-82 anos, com média de 37,4 anos. Houve maior incidência no sexo masculino (66,6%). Ocorreu diferença na distribuição do olho acometido (maior no olho direito - 65,2%). Quanto à história de cirurgia oftalmológica prévia, 12 dos 23 olhos tinham história positiva (52,2%). Observamos que nos pacientes em que foi possível a avaliação da acuidade visual pré-operatória, todos apresentaram melhora ou manutenção da acuidade visual. No pós-operatório foi observado complicações associadas à doença de base e não propriamente ao transplante de membrana amniótica. Não foram registrados casos de infecção pós-operatória. Conclusão: Houve melhora do estado geral da superfície ocular em quase totalidade dos casos em que o transplante foi realizado. Portanto, a membrana amniótica pode ser considerada uma boa alternativa para reconstrução da superfície ocular, como tratamento único ou coadjuvante.

Combined transscleral fixation of an artificial iris prosthesis with an intraocular lens / Combinação de fixação transescleral de prótese de íris artificial com lente intraocular

ABSTRACT Post-traumatic aniridia combined with aphakia may be seen after globe injury. Aside from esthetic aspects, partial or total loss of the iris tissue may also be related to various degrees of glare and photophobia. Such patients suffer from severe visual impairment secondary to aphakia. Herein we describe a novel surgical technique for the management of an aphakic eye with traumatic aniridia for a patient who underwent transscleral fixation of a custom-tailored artificial iris prosthesis combined with a rigid intraocular lens (IOL). Tight suturing of the IOL haptic eyelets on the silicone iris prosthesis and fixation of such a complex to the scleral wall may provide excellent cosmetic and functional outcomes in aphakic eyes with aniridia.

RESUMO Aniridia pós-traumática combinada com afacia pode ser observada após lesões do globo ocular. Além do ponto de vista estético, a perda parcial ou total do tecido da íris também pode estar relacionada com vários graus de ofuscamento e fotofobia. Estes pacientes sofrem de deficiência visual grave secundária a afacia. Relata-se uma técnica cirúrgica inovadora para tratamento de um olho com afacia associada à aniridia traumática que foi submetido à fixação transescleral de uma prótese de íris artificial feita sob medida combinada com uma lente intraocular rígida (IOL). A sutura das alças da IOL sobre a prótese iriana de silicone, e a fixação desse complexo na parede escleral podem proporcionar excelente resultado estético e funcional em olhos afácicos com aniridia.

Traumatismo accidental con estallido del globo ocular / Accidental trauma with eyeball popping-up

Paciente masculino de 27 años de edad, trabajador agrícola, que fue ingresado en el Hospital Militar Central "Dr. Carlos J. Finlay" por haber sufrido una herida penetrante por arma de fuego, producida por la impulsión retrógrada del percutor al disparar una escopeta artesanal de cacería, que provocó estallido del globo ocular izquierdo, fractura de la pared externa de la órbita y heridas palpebrales. Se retiró el cuerpo extraño, se completó la evisceración del ojo izquierdo, se recolocó el fragmento fracturado de la órbita en posición anatómica, se regularizaron los tejidos blandos intra y periorbitarios, preparando la cavidad orbitaria para la colocación posterior de la prótesis; y se realizó la hemostasia, la exploración de la cavidad neoformada por el cuerpo extraño en los tejidos blandos de la región fronto-temporal y la plastia palpebral. Se logró con éxito la reconstrucción palpebral y con posterioridad, la rehabilitación con fines estéticos mediante prótesis ocular.

A 27 year-old male farmer patient was admitted to "Dr. Carlos J. Finlay" Central Military Hospital suffering a penetrating gunshot wound, caused by the retrograde hammer when shooting a handmade hunting shotgun. This injured caused his left eyeball burst, fracture of the outer wall of the orbit and eyelid injuries. Foreign matter was removed. His left eye evisceration was completed. The fractured orbit fragment was repositioned in anatomical position. Intra and periorbital soft tissues were regularized, preparing the orbital cavity for the subsequent placement of prosthesis; and hemostasis was performed, as well as exploration the newly formed cavity by foreign matter in the soft tissues of the frontal-temporal region and eyelid plasty. Eyelid reconstruction and further rehabilitation for aesthetic purposes by ocular prosthesis was successfully achieved.

Direct cyclopexy surgery for post-traumatic cyclodialysis with persistent hypotony: ultrasound biomicroscopic evaluation / Ciclopexia direta em ciclodiálise pós-traumática com hipotonia ocular persistente -acompanhamento por biomicroscopia ultrassônica (UBM)

Cyclodialysis is a relatively rare condition usually caused by ocular injury; however, it can also be caused iatrogenically during intraocular surgery. Hypotony maculopathy is the most important complication and the primary reason for visual loss. Clinical diagnosis using gonioscopy may be difficult, and ultrasound biomicroscopy (UBM) can be an alternative. There are different kinds of treatments, and the optimal one remains controversial. Here we describe a case of traumatic cyclodialysis with persistent ocular hypotony treated by direct cyclopexy, as illustrated by UBM performed before and after surgery.

Ciclodiálise é uma condição relativamente rara, geralmente devido a um trauma ocular, mas também pode ser causada iatrogenicamente como consequência de cirurgia intraocular. A maculopatia hipotônica é a complicação mais importante e a principal razão para a perda visual nessa situação. O diagnóstico clínico por gonioscopia pode ser difícil e a biomicroscopia ultrassônica (UBM) pode ser uma alternativa. Existem diferentes tipos de tratamentos e algumas controvérsias sobre a melhor opção. Neste relato, nós descrevemos um caso de ciclodiálise traumática com hipotonia ocular persistente tratado por cyclopexia direta avaliado por UBM antes e depois da cirurgia.

Introduction of Lens-angle Reconstruction Surgery in Rabbit Eyes

PURPOSE: In this study, we examined the stability of the lens-angle supporter (LAS) for accommodation restoration by comparing intraocular lens (IOL) location, after-cataract and ciliary body damage after cataract surgery in rabbits. METHODS: Eight rabbits were divided into experimental and control groups of four rabbits each. Phacoemulsification and irrigation and aspiration were performed in all rabbits. This was followed by an LAS and IOL insertion in the four experimental rabbits. In the four control rabbits, only an IOL insertion was performed. Six months after the surgery, the location of the IOL, the conditions of the lens capsule and ciliary body were evaluated using a slitl-amp examination and Miyake-Apple view. RESULTS: For the experimental group, the ultrasound biomicroscope results showed normal LAS and IOL positioning in all four cases. According to the slitlamp examination and Miyake-Apple view, the IOL was positioned at the center, with less after-cataract and damage to the ciliary body. For the control group, ultrasound biomicroscope results indicated a higher IOL position than normal, as well as a single case of IOL decentering. According to the slit-lamp examination and Miyake-Apple view, the IOL was decentered with more severe after-cataract and ciliary body damage. CONCLUSIONS: The LAS has the potential to maintain a stable IOL position while producing less after-cataract when used in lens-angle reconstruction for correction of presbyopia. Moreover, LAS implantation incurs less damage to the ciliary body.

OBJETIVO: Avaliar os resultados anatômicos e visuais de pacientes com catarata traumática atendidos no Hospital de Olhos do Paraná, apresentando ou não alterações oculares associadas e que foram submetidos ao tratamento cirúrgico, além de traçar o perfil analisando tipo de trauma, relação entre ocupação e trauma, relação entre tipo de trauma e prognóstico visual, correlacionando acuidade visual (AV) pré e pós-operatória. MÉTODOS: Após minuciosa avaliação oftalmológica foram coletados os seguintes dados: sexo, idade, ocupação, tipo de trauma, AV pré e pós-tratamento, alterações oculares associadas e dos pacientes que foram submetidos à cirurgia as complicações pós-operatórias mais frequentes. RESULTADOS: Foram atendidos 45 pacientes com catarata traumática. Destes, 25 submeteram-se à cirurgia. A maioria dos pacientes era do sexo masculino (88%), sofreu trauma contuso (52%) e apresentou idade média de 43,16 anos, atingindo uma faixa etária economicamente ativa. Estes traumas foram classificados como: laboral (14), recreacional, doméstico e automobilístico. Subluxação de cristalino foi a alteração ocular associada mais observada. Vinte e dois pacientes (88%) apresentaram visão inicial ≥ 20/400, entre os submetidos à cirurgia, 64% apresentaram melhor acuidade visual corrigida pela tabela de Snellen (MAVC) ≤ 20/40. Opacidade cápsula posterior foi a complicação pós-operatória mais frequente. CONCLUSÃO: O perfil dos pacientes atendidos, no HOP, com catarata traumática é, na grande maioria, homens com idade média de 43 anos, vítimas de trauma contuso ocorridos quando desenvolviam atividades laborais, expostos ao risco de acidente sem equipamentos de proteção, atingindo principalmente agricultores, pedreiros e serralheiros. Esses, após o tratamento cirúrgico apresentaram melhora significativa da visão.

OBJECTIVE: To evaluate the anatomic and the visual results of patients with traumatic cataract who sought care in Hospital de Olhos do Paraná (HOP), that were subjected to surgical treatment in this service. To describe their epidemiological and clinical aspects, and to analyze the post operative functional results. METHODS: There were included in the study all patients subjected to a surgical treatment and the following characteristics were analyzed: sex, age, pre and postoperative visual acuity, mechanism of trauma, associated ocular alterations and most frequent postoperative complications. RESULTS: Forty five patients were treated with clinical diagnosis of traumatic cataract during the study period. From the total, 25 were submitted the surgical treatment. The majority of patients were male (88%), a history of blunt trauma could be ascertained (52%) middle age 43±16 years reaching an economically active group. Manual laborers were the most frequent (14), followed by recreational accidents, home accidents and automobilistic accidents. Traumatic subluxation lens were the most frequent ocular alterations associated. Twenty two patients (88%) presented pre-operative visual acuity ≥ 20/400. Among the patients that were submitted to cataract surgery, 64% showed better visual acuity corrected by table of Snellen ≤ 20/40. Cause of poor post operative visual acuity posterior capsule opacity CONCLUSION: In this study, the majority of patients were male, with mean age of 43±16 years and victims of blunt trauma during their job without equipments of protection, reaching principally farmers, masons and locksmiths. It was observed a clear improvement of postoperative visual acuity among these patients.

Outcome of in-the-bag implanted square-edge polymethyl methacrylate intraocular lenses with and without primary posterior capsulotomy in pediatric traumatic cataract.

Purpose: To study the outcome of in-the-bag implanted square-edge polymethyl methacrylate (PMMA) intraocular lenses (IOL) with and without primary posterior capsulotomy in pediatric traumatic cataract. Materials and Methods: The study was undertaken in a tertiary care center. Thirty eyes of 30 children ranging in age from 4 to 16 years with traumatic cataract which underwent cataract extraction with capsular bag implantation of IOL were prospectively evaluated. Group A included 15 eyes of 15 children where primary posterior capsulotomy (PPC) and anterior vitrectomy with capsular bag implantation of square-edge PMMA IOL (Aurolab SQ3602, Madurai, Tamil Nadu, India) was performed. Group B comprised 15 eyes of 15 children in which the posterior capsule was left intact. Postoperative visual acuity, visual axis opacification (VAO) and possible complications were analyzed. Results: Best corrected visual acuity (BCVA) of 20/40 or better was achieved in 12 of 15 eyes in both groups. Amblyopia was the cause of no improvement in visual acuity in the remaining eyes. Visual axis opacification was significantly high in Group B as compared to Group A (P=0.001). Postoperative fibrinous uveitis occurred in most of the eyes in both groups. Pupillary capture was observed in one eye in each group. Conclusion: Primary posterior capsulotomy and anterior vitrectomy with capsular bag implantation of square-edge PMMA significantly helps to maintain a clear visual axis in children with traumatic cataract.

Fístula liquórica traumática com luxação de globo ocular: relato de caso / Management of globe luxation followed by traumatic liquoric fistula: case report

This report describes the only case in the literature of globe luxation due to traumatic cerebrospinal fluid fistula to the orbit caused by fire gun with ocular globe maintenance. E.N., female, white, 7 months, admitted with left orbitocranial injury by fire gun. Ocular globe luxation was detected with complete ocular motility restriction and absence of pupillary reflex in the left orbit. Computed tomography showed fracture of the medial orbital wall; bone fragments near the apex of the orbit and a stretched optic nerve. Surgical exploration was performed, showing liquor fistula through the ethmoid-sphenoid wall that was blocked with sponge (Gelfoam®) plus organic glue in the left orbit posterior wall, with immediate resolution of the proptosis and ocular integrity maintenance. Although controversial, maintenance of the ocular globe instead of enucleation was performed due to the integrity of the globe in this case. Despite the blindness, we considered the result to the proposed treatment excellent, once the maintenance of the ocular globe provides a good appearance and will contribute to an adequate facial bone development.

O presente estudo apresenta o único caso de luxação de globo ocular devido fístula liquórica traumática em vítima de trauma órbito-cerebral por projétil de arma de fogo com a preservação do globo ocular. E.N., feminino, branca, 7 meses, admitida com ferimento por projétil de arma de fogo em região órbito-craniana esquerda. Apresentava luxação de globo ocular esquerdo com restrição completa da motilidade ocular e reflexo fotomotor ausente à esquerda. À tomografia: fraturas da parede medial da órbita; fragmentos ósseos próximos ao ápice da órbita. Realizou-se exploração cirúrgica, evidenciando-se fístula liquórica através de fratura etmoido-esfenoidal a qual foi tamponada com esponja (Gelfoam®) e cola orgânica na parte posterior da parede medial da órbita esquerda, com regressão imediata da luxação do globo ocular, sendo o mesmo mantido íntegro. Embora controversa na literatura, optou-se pela preservação do globo ocular à enucleação, visto que o mesmo estava íntegro. Apesar da cegueira, consideramos um excelente resultado ao tratamento proposto, tendo em vista que a preservação do globo ocular provém uma boa aparência, favorecendo também o desenvolvimento ósseo da face.
