ABSTRACT Purpose: To compare 0.5 mg and 0.625 mg of bevacizumab for treating aggressive posterior retinopathy of prematurity (AP-ROP). Methods: The medical records of patients with AP-ROP who were administered intravitreal bevacizumab (IVB) as a primary treatment at a university clinic were evaluated retrospectively. Five eyes of three patients (Group 1) who received 0.625 mg/0.025 ml IVB and 10 eyes of another five patients (Group 2) who received 0.5 mg/0.02 ml IVB were evaluated. Laser photocoagulation was used as additional treatment after relapses. Anatomic results and complications were evaluated in both groups. Results: We evaluated 15 eyes of eight patients (four girls and four boys) with a flat demarcation line at posterior zone 2 and plus disease or stage-3 disease in this study. The mean gestational age of the three babies in Group 1 was 26 ± 1 weeks and the mean birth weight was 835.33 ± 48.01 g. The corresponding values were 25.2 ± 1.6 weeks and 724 ± 139.03 g, respectively, for the five babies in Group 2. Retinal vascularization was completed at a mean postmenstrual duration of 53.6 ± 1.5 weeks without additional treatment in the five eyes in Group 1. Laser photocoagulation for relapse was administered to five of the 10 eyes in Group 2. Retinal vascularization was completed at a mean postmenstrual duration of 47.6 ± 1.5 weeks in the remaining five eyes. None of the patients developed complications such as cataract, glaucoma, retinal tear, retinal or vitreous hemorrhage, or retinal detachment. Conclusion: Although lower IVB doses in the treatment of AP-ROP are expected to be safer in terms of local and systemic side effects in premature infants, these patients may require additional treatment with IVB or laser photocoagulation.
RESUMO Objetivo: Comparar doses de 0,5 mg e 0,625 mg de bevacizumab no tratamento da retinopatia da prematuridade posterior agressiva (ROP-PA). Métodos: os registros médicos de pacientes com ROP-PA que receberam bevacizumab intravítreo (IVB) como tratamento primário em uma clínica universitária foram avaliados retrospectivamente. Houve 5 olhos de 3 casos (Grupo 1) que receberam 0,625 mg/0,025 ml de IVB e 10 olhos de outros 5 casos (Grupo 2) que receberam 0,5 mg/0,02 ml de IVB. A fotocoagulação com laser foi utilizada como tratamento adicional para casos de recidiva. Os resultados e complicações anatômicas foram avaliados em ambos os grupos. Resultados: Incluímos os 15 olhos de 8 pacientes (4 meninas e 4 meninos) com linha de demarcação plana na zona posterior 2 e doença "plus" (dilatação e tortuosidade vascular) neste estudo. A idade gestacional média dos três bebês no Grupo 1 foi de 26 ± 1 semana e o peso médio ao nascer foi de 835,33 ± 48,01 g, enquanto esses valores foram de 25,2 ± 1,6 semanas e 724 ± 139,03 g, respectivamente, para os cinco bebês do Grupo 2. A vascularização da retina foi completada com uma duração média pós-menstrual de 53,6 ± 1,5 semanas sem tratamento adicional nos cinco olhos no Grupo 1. A fotocoagulação a laser foi administrada devido à recaída em 5 dos 10 olhos do Grupo 2. A vascularização da retina foi completada em média de 47,6 ± 1,5 semanas do período pós-menstrual nos cinco olhos restantes. Nenhum dos casos desenvolveu complicações, como catarata, glaucoma, rasgo da retina, hemorragia retiniana ou vítrea ou descolamento da retina. Conclusão: Embora as doses mais baixas de IVB no tratamento de ROP-PA sejam mais seguras em termos de efeitos colaterais locais e sistêmicos em prematuros, esses pacientes podem precisar de tratamento adicional com IVB ou fotocoagulação a laser.

ABSTRACT Purpose: To evaluate the retinal vascularization process after intravitreal ranibizumab was administered to infants with aggressive posterior retinopathy of prematurity (AP-ROP). Methods: Twenty-six eyes of 13 infants with AP-ROP who received 0.25 mg intravitreal ranibizumab were retrospectively investigated. The patients were evaluated at weekly follow-up visits, and the findings were analyzed after retinal vascularization was complete. Results: The results showed regression in the AP-ROP of all the patients within the first 48-72 h. Average time for complete vascularization of the nasal quadrant (zone II) was postmenstrual week 45 (range 41-56), and vascularization of the temporal quadrant (zone III) was completed in the postmenstrual week 56 (range 50-65). Reactivation was observed in seven patients, on average at postmenstrual week 42; two of these patients underwent additional treatment. Two patients presented with avascular areas in the peripheral retina despite being 1 year old. Conclusion: These results showed that retinal vascularization following intravitreal ranibizumab was completed after a delay in patients with AP-ROP. Further studies are necessary to evaluate when and how vascularization occurs after intravitreal anti-vascular endothelial growth factor treatments.
RESUMO Objetivo: Avaliar o processo de vascularização da retina após injeção intravítrea de ranibizumab aplicada em crianças com retinopatia da prematuridade posterior agressiva (AP-ROP). Métodos: Vinte e seis olhos de 13 crianças com AP-ROP que receberam 0,25 mg de ranibizumab intravítreo foram investigados retrospectivamente. Os resultados foram avaliados após a completa vascularização da retina, observada em acompanhamentos semanais. Resultados: Verificou-se que houve regressão na AP-ROP de todos os pacientes durante as primeiras 48 a 72 horas. Na média, a vascularização do quadrante nasal (zona II) foi concluída na semana 45 pós-menstrual (variação 41-56), enquanto a vascularização do quadrante temporal (zona III) foi concluída na semana 56 pós-menstrual (variação 50-65). Sete pacientes (7/13) apresentaram reativação, que aconteceram em média a 42,14 semanas pós-menstruais, dois pacientes receberam tratamento adicional. Dois pacientes apresentaram áreas avasculares na retina periférica apesar de terem um ano de idade. Conclusões: O presente estudo mostrou que a vascularização da retina após a injeção intravítrea de ranibizumab foi concluída com atraso na AP-ROP. Ensaios clínicos randomizados são necessários para avaliar quando e como a vascularização acontece após tratamentos com injeções intravítreas de anti-VEGF.

ABSTRACT Purpose: To compare the efficacy of intravitreal ranibizumab and bevacizumab treatment for type 1 retinopathy of prematurity (ROP). Methods: 36 eyes of 20 patients with type 1 ROP who received anti-vascular endothelial growth factor (anti-VEGF) intravitreal injections between August 2011 and February 2013 were retrospectively evaluated. Fifteen eyes of 8 patients received 0.25 mg ranibizumab (group 1), and 21 eyes of 12 patients received 0.625 mg bevacizumab (group 2). Eyes were examined by indirect ophthalmoscopy on the first day, third day, first week, and first month and as required after injections. Laser photocoagulation was performed in cases with progression of ROP. Results: The mean gestation time was 26.2 ± 2.7 weeks in group 1 patients and 27.1 ± 2.5 weeks in group 2 patients. No statistical difference in the time of gestation was observed between the two groups. The mean follow-up period was 20 ± 4.5 months. Laser photocoagulation was performed in 6 of 15 eyes from group 1 and 2 of 21 eyes from group 2. No eyes developed retinal detachment during the follow-up period. Conclusion: Ranibizumab and bevacizumab showed an efficacy in the treatment of type 1 ROP. The incidence of disease relapse was higher in eyes which received ranibizumab. Further randomized, controlled clinical trials are required to compare the efficacy of ranibizumab and bevacizumab.
RESUMO Objetivo: Comparar a eficácia de ranibizumab e bevacizumab intravítreos no tratamento da retinopatia da prematuridade (ROP) tipo 1. Método: Foram avaliados retrospectivamente 36 olhos de 20 pacientes com retinopatia da prematuridade tipo 1 que receberam injeções intravítreas anti fator de crescimento endotelial vascular (anti VEGF) entre agosto de 2011 e fevereiro 2013. Quinze olhos de 8 pacientes receberam 0,25 mg ranibizumab (grupo 1) e 21 olhos de 12 pacientes receberam 0,625 mg bevacizumab (grupo 2). Os olhos foram examinados por oftalmoscopia indireta no primeiro dia, terceiro dia, primeira semana, e primeiro mês e conforme necessário após a injeção. Fotocoagulação com laser foi realizada quando foi detectada progressão da retinopatia da prematuridade. Resultados: Média do tempo de gestação para os pacientes do grupo 1 foi de 26,2 ± 2,7 semanas, enquanto para o grupo 2 foi de 27,1 ± 2,5 semanas. Não houve diferença estatística em relação ao tempo de gestação entre os grupos. A média de acompanhamento foi de 20 ± 4,5 meses. Fotocoagulação a laser foi realizada a 6 dos 15 olhos do grupo 1 e 2 dos 21 olhos do grupo 2. Nenhum dos olhos desenvolveu descolamento de retina no período de acompanhamento. Conclusão: O ranibizumab e bevacizumab são eficazes no tratamento da retinopatia da prematuridade tipo 1. Incidência de progressão foi maior nos olhos que receberam ranibizumab. Ensaios clínicos controlados futuros são necessários para comparar esses dois medicamentos.

ABSTRACTPurpose:To evaluate 2-year outcomes following intravitreal bevacizumab (IVB) as monotherapy for aggressive posterior retinopathy of prematurity (APROP).Methods:Medical records of 40 infants were retrospectively reviewed. Group I included infants who had received IVB injections for APROP. Group II included infants who underwent laser treatment for APROP. Anatomic and refractive outcomes and the presence of anisometropia and strabismus were assessed at follow-up examinations.Results:Group I included 48 eyes of 25 infants (11 males) with a mean gestational age (GA) of 26.40 ± 1.82 weeks and a mean birth weight (BW) of 901.40 ± 304.60 g. Group II included 30 eyes of 15 infants (6 males) with a mean GA of 27.30 ± 1.82 weeks and a mean BW of 941.00 ± 282.48 g. GA, BW, and gender distributions were similar between groups (P=0.187, P=0.685, and P=1.000, respectively). Refractive errors were significantly less myopic in group I (0.42 ± 3.42 D) than in group II (-6.66 ± 4.96 D) at 2 years (P=0.001). Significantly higher rates of anisometropia and strabismus were observed in group II than in group I (P=0.009 and P=0.036, respectively).Conclusions:The study demonstrated that IVB monotherapy can be useful in the treatment of APROP. The decreased incidence of early unfavorable refractive and functional outcomes in the IVB group compared with the laser group showed a potential benefit for patients treated with IVB, and this needs to be better evaluated in future prospective studies.
RESUMOObjetivo:Avaliar a evolução de 2 anos em crianças que receberam bevacizumab intravítreo (IVB) como monoterapia para retinopatia da prematuridade posterior agressiva (APROP).Métodos:Arquivos médicos de 40 crianças foram revisados retrospectivamente. Grupo I incluiu as crianças que tiveram injeções IVB para APROP. Grupo II foi composto por crianças que se submeteram a tratamento a laser para APROP. Os resultados anatômicos e refracionais, presença de anisometropia e estrabismo foram avaliados durante exames de acompanhamento.Resultados:Grupo I incluiu 48 olhos de 25 crianças (11 do sexo masculino) com média de idade gestacional (GA) de 26,40 ± 1,82 semanas, e média de peso ao nascimento (BW) de 901,40 ± 304,60 g. Grupo II incluiu 30 olhos de 15 crianças (6 do sexo masculino) com GA de 27,30 ± 1,82 semanas e BW de 941,00 ± 282,48 g. GA, BW e distribuição por sexo foram semelhantes entre os grupos (p=0,187, p=0,685, p=1,000, respectivamente). Nenhuma anormalidade anatômica foi observada em ambos os grupos. Erro refrativo foi significativamente menos míope no grupo I (0,42 ± 3,42 D) do que o grupo II (-6,66 ± 4,96 D) em exames aos 2 anos (p=0,001). Houve significativamente maior taxa de anisometropia e estrabismo no grupo II em relação ao grupo I (p=0,009, p=0,036, respectivamente).Conclusões:O estudo demonstrou que a monoterapia IVB pode ser útil no tratamento de APROP. A diminuição da incidência de resultados refracionais e funcionais desfavoráveis precoces no grupo IVB em comparação com o grupo do laser mostraram um benefício potencial para os pacientes tratados com IVB, e isto tem de ser melhor avaliado em estudos prospectivos no futuro.

This study was conducted to describe the incidence, risk factors, and current treatment status of retinopathy of prematurity (ROP) in very-low-birth-weight (VLBW) infants registered in the Korean Neonatal Network database. Medical records of 2,009 VLBW infants born between January 2013 and June 2014 who underwent examination by an ophthalmologist were reviewed. The total incidence of ROP was 34.1%. Of the patients, 11.6% showed ROP stage > or = 3 and 11.5% received treatment of VLBW. Among all infants who received treatment of ROP, 63.6% underwent operation only; 16.9%, anti-vascular endothelial growth factor (anti-VEGF) treatment only; and 19.5%, both operation and anti-VEGF treatment. The mean gestational age (GA) and birth weight (BW) were significantly lower and the prevalence rates of respiratory distress syndrome, patent ductus arteriosus (PDA), invasive ventilator duration, and sepsis were significantly higher in the VLBW infants with ROP than in those without ROP. In the multivariable logistic regression analysis, PDA (odd ratio [OR], 2.1; 95% confidence interval [CI], 1.11-3.79) and invasive ventilator duration (OR, 1.0; 95% CI, 1.00-1.02) were significant risk factors of ROP and ROP stage > or = 3. In conclusion, the high incidence of ROP is associated with low GA and BW, and attempt to reduce the aforementioned risk factors could reduce the incidence of ROP stage > or = 3 in VLBW infants.

Comunicamos los resultados oftalmológicos en una serie de niños tratados con bevacizumab intravítreo con retinopatía del prematuro (RDP) en etapa umbral. Se evaluaron doce recién nacidos pretérmino de muy bajo peso (RNMBP) que recibieron bevacizumab intravítreo como monoterapia en el tratamiento de la retinopatía del prematuro en etapa umbral y que presentaban contraindicación para la terapia estándar con fotocoagulación con láser. Se realizaron controles oftalmológicos y se evaluó la respuesta al tratamiento, reintervenciones y complicaciones. La edad gestacional de estos pacientes fue 26,3 ± 1,8 semanas y el peso de nacimiento de 845 ± 153 g. Hubo buena respuesta en ocho casos, mientras que cuatro pacientes requirieron reintervención con fotocoagulación con láser. No se detectaron complicaciones inmediatas y no hubo pacientes fallecidos.
Ophthalmological outcomes in a series of children with retinopathy of prematurity (ROP) in the threshold stage treated with intravitreal bevacizumab are reported. Twelve very low birth weight (VLBW) preterm infants who were administered intravitreal bevacizumab as monotherapy for retinopathy of prematurity in the threshold stage and in whom standard laser photocoagulation therapy was contraindicated were evaluated. Ophthalmological examinations were carried out and response to treatment, second interventions, and complications were evaluated. The gestational age of these patients was 26.3 ± 1.8 weeks and their birth weight was 845 ± 153 g. A good response was observed in eight cases, while four patients required to be reintervened with laser photocoagulation. No immediate complications were detected and there were no deaths.

Introducción: El tratamiento estándar de la Retinopatía del Prematuro (RDP) en etapa umbral es la fotocoagulación con láser (FCL). Recientemente se ha utilizado el bevacizumab, un inhibidor del factor de crecimiento del endotelio vascular (VEGF) con resultados alentadores. Objetivo: Comunicar el resultado del tratamiento con bevacizumab en Recién Nacidos (RN) prematuros con retinopatía en etapa umbral. Pacientes y Método: Se analizaron los RN pretérmino de muy bajo peso (RNMBP) que recibieron bevacizumab, en monoterapia o asociado a FCL, como tratamiento de la RDP en etapa umbral. Se evaluó respuesta al tratamiento, reintervenciones y complicaciones. Resultados: Se analizaron 17 RNMBP con promedio de edad gestacional 26,4 +/- 1,7 sem y peso de nacimiento de 850 +/- 141 g. Los 6 pacientes tratados con bevacizumab en asociación a FCL no requirieron reintervención. De los 11 neonatos que sólo recibieron bevacizumab, el 36,3 por ciento necesitó posteriormente tratamiento con FCL. Conclusiones: El bevacizumab sería una terapia efectiva en el tratamiento de la RDP umbral. En nuestra experiencia presentó ventajas respecto a la FCL, al ser realizado sin necesidad de traslado del RN ni de uso de anestesia general. No observamos complicaciones a corto plazo con el uso de bevacizumab en los pacientes tratados.
Introduction: Standard treatment of threshold Retinopathy of Prematurity (ROP) is laser photocoagulation (LPC). Recently, bevacizumab, a vascular endothelial growth factor (VEGF) inhibitor has been used with positive results. Objective: To communicate the response to treatment with bevacizumab in premature newborns with threshold retinopathy. Patients and Method: Very low birth weight (VLBW) infants that received bevacizumab, in monotherapy or associated with LPC, as treatment for threshold ROP, were analyzed. Response to treatment, reinterventions and complications were evaluated. Results: 17 VLBW infants were analyzed with mean gestational age 26.4 +/- 1.7 weeks and mean birth weight 850 +/- 141 g. All 6 patients treated with bevacizumab in association with LPC did not require reintervention. Of the 11 neonates that only received bevacizumab, 36.3 percent needed further treatment. Conclusions: Bevacizumab could be an effective therapy for treatment of threshold ROP. In our experience it presented advantages compared with LPC, since therapy can be carried out without transferring the patient and with no use of general anesthetics. No short term complications were observed with the use of bevacizumab in treated patients.

La retinopatía del prematuro es una vasculopatía retinal proliferativa, en la que la vascularización normal de la retina se ve interrumpida por el nacimiento precoz, lo que provoca que áreas de retina isquémica produzcan factores vasoproliferativos que determinan neovascularización y sus consecuencias (desprendimiento de retina). En la medida que ha existido un notable desarrollo de unidades de cuidado neonatal, el número de prematuros que logra sobrevivir a esta condición es mayor, lo que implica un incremento de la incidencia de retinopatía asociada. Este estudio retrospectivo analiza a los recién nacidos prematuros nacidos en el Hospital San Juan de Dios entre los años 2000 y 2001, de 116 pacientes atendidos se consideraron sólo una población de 84 con registros completos, obteniéndose una prevalencia de retinopatía de 14,3 por ciento. Entre los factores de riesgo detectados se aprecia el peso de nacimiento (promedio 991 g vs 1.258 g), edad gestacional (promedio 27,8 vs 31 sem), tiempo de oxígenoterapia (promedio 28 vs 7,8 días), uso de dopamina y surfactante pulmonar. No hubo diferencias significativas en el tipo de oxígenoterapia usada, uso de corticoides o de antimicrobianos prenatales ni tampoco en relación al puntaje Apgar. Estos resultados demuestran que nuestra realidad en términos de factores de riesgo no difiere mayormente de la situación mundial, lo que nos impone nuevos desafíos para mejorar la detección y el tratamiento de la retinopatía del prematuro, disminuyendo el número de niños ciegos en nuestro país
