ABSTRACT

ABSTRACT Purpose: To evaluate the effectiveness of intravitreal aflibercept treatment for macular edema with and without serous retinal detachment due to branch retinal vein occlusion. Methods: Thirty-seven eyes with branch retinal vein occlusion treated with intravitreal aflibercept injection for macular edema were evaluated retrospectively. The patients were divided into two groups according to whether they showed serous retinal detachment on spectral domain optical coherence tomography. Pro re nata regimen was applied after 1 dose of intravitreal aflibercept injection. After the initial injection, control treatments were administered at months 1, 2, 3, 6, and 12. The best-corrected visual acuity and central macular thickness were measured. Results: Fifteen patients had serous retinal detachment, and 22 with macular edema only (non-serous retinal detachment). The central macular thickness was significantly greater in the group with than in the group without serous retinal detachment (811.73 ± 220.68 µm and 667.90 ± 220.68 µm, respectively, p=0.04). The difference between the groups disappeared from the third month. The central macular thickness was similar between the two groups at the last control treatment (407.27 ± 99.08 µm and 376.66 ± 74.71 µm, p=0.66). The best-corrected visual acuity increased significantly in both groups. No significant difference was found between the two groups in terms of the best-corrected visual acuities at baseline and the final control. Conclusion: The intravitreal aflibercept treatment was highly effective in improving best-corrected visual acuity and central macular thickness in patients with branch retinal vein occlusion-induced macular edema independent of serous retinal detachment.


RESUMO Objetivo: Avaliar a eficácia do tratamento com aflibercepte intravítreo para edema macular devido à oclusão de um ramo da veia retiniana, com e sem descolamento seroso da retina. Métodos: Foram analisados retrospectivamente 37 olhos com oclusão de um ramo da veia retiniana, tratados com injeção intravítrea de aflibercepte para edema macular. Os pacientes foram divididos em dois grupos, de acordo com a presença ou ausência de um descolamento seroso de retina na tomografia de coerência óptica (SD-OCT). Um regime pro re nata foi seguido após 1 injeção intravítrea de aflibercepte. Após a injeção, foram realizadas consultas de acompanhamento nos meses 1, 2, 3, 6 e 12. Foram medidas a melhor acuidade visual corrigida e a espessura macular central. Resultados: Houve 15 pacientes com descolamento seroso de retina e 22 pacientes com apenas edema macular (descolamento não seroso de retina). A espessura macular central foi significativamente maior no grupo com descolamento seroso de retina do que no grupo com descolamento não seroso de retina (respectivamente, 811,73 ± 220,68 µm e 667,90 ± 220,68 µm; p=0,04). A diferença desapareceu a partir do terceiro mês. A espessura macular central foi semelhante nos dois grupos na última consulta (407,27 ± 99,08 µm e 376,66 ± 74,71 µm, p=0,66). A melhor acuidade visual corrigida aumentou significativamente em ambos os grupos. Não houve diferença entre os dois grupos quanto à melhor acuidade visual corrigida inicial e final. Conclusão: O tratamento com aflibercepte intravítreo foi altamente eficaz em melhorar a acuidade visual corrigida e a espessura macular central no edema macular induzido pela oclusão de um ramo da veia retiniana, independentemente da presença ou não de um descolamento seroso da retina.

ABSTRACT

ABSTRACT Purpose: To investigate the effects of epiretinal membrane formation on the clinical outcomes of intravitreal dexamethasone implantation for macular edema secondary to branch retinal vein occlusion. Methods: This retrospective interventional case series includes the treatment of naive patients with macular edema secondary to non-ischemic branch retinal vein occlusion who underwent intravitreal dexamethasone implantation. The patients were divided into two groups as follows: Group 1 (n=25), comprised of patients with macular edema secondary to branch retinal vein occlusion without epiretinal membrane, and Group 2 (n=16), comprised of patients with macular edema secondary to branch retinal vein occlusion with an epiretinal membrane. Corrected visual acuity, central macular thickness, and central macular volume values were measured before and after treatment. The clinical outcomes of the groups were compared. Results: Mean age and male-to-female ratio were similar between the two groups (p>0.05, for both). The baseline and final corrected visual acuity values, central macular thickness, and central macular volumes of the groups were similar (p>0.05, for all). All the parameters were significantly improved after intravitreal dexamethasone implantation treatment (p<0.001, for all). The changes in central macular thickness and volume were also similar (p>0.05, for both). The mean number of intravitreal dexamethasone implantations was 2.1 ± 1.0 (range, 1-4) in Group 1 and 3.0 ± 1.2 (range, 1-5) in Group 2 (p=0.043). Conclusion: Epiretinal membrane formation had no effects on the baseline and final clinical parameters, including corrected visual acuity and central macular thickness and volume. The only parameter affected by the presence of epiretinal membrane formation is the number of intravitreal dexamethasone implantations, a greater number of which is needed for macular edema secondary to branch retinal vein occlusion with an epiretinal membrane.


RESUMO Objetivo: Investigar os efeitos da formação de uma membrana epirretiniana nos resultados clínicos da implantação intravítrea de dexametasona para edema macular secundário à oclusão de um ramo da veia retiniana. Métodos: Esta série retrospectiva de casos intervencionais inclui o tratamento de indivíduos com edema macular secundário à oclusão não isquêmica de um ramo da veia retiniana, sem tratamento prévio e que foram submetidos a implantação intravítrea de dexametasona. Os indivíduos foram divididos em dois grupos: Grupo 1 (n=25), composto por indivíduos com edema macular secundário à oclusão de um ramo da veia retiniana sem a presença de uma membrana epirretiniana, e Grupo 2 (n=16), composto por indivíduos com edema macular secundário à oclusão de um ramo da veia retiniana com a presença de uma membrana epirretiniana. Os valores da acuidade visual corrigida, espessura macular central e volume macular central foram obtidos antes e após o tratamento. Os resultados clínicos dos grupos foram comparados. Resultados: A média de idade e a proporção entre homens e mulheres foram semelhantes nos dois grupos (p>0,05 para ambos os valores). Os valores iniciais e finais da acuidade visual corrigida, espessura macular central e volume macular central foram semelhantes nos dois grupos (p>0,05 para todos os valores). Todos os parâmetros melhoraram significativamente após o tratamento com implante de dexametasona intravítrea (p<0,001 para todos os parâmetros) e as alterações na espessura macular central e no volume macular central também foram semelhantes (p>0,05 para ambos os valores). O número médio de implantações intravítreas de dexametasona foi 2,1 ± 1,0 (faixa de 1-4) no Grupo 1 e 3,0 ± 1,2 (faixa de 1-5) no Grupo 2 (p=0,043). Conclusão: A formação de uma membrana epirretiniana não tem efeitos sobre os parâmetros clínicos iniciais e finais, incluindo a acuidade visual corrigida, a espessura macular central e o volume macular central. O único parâmetro afetado pela formação de uma membrana epirretiniana é o número de implantações intravítreas de dexametasona, sendo necessário um número maior de implantações em casos de edema macular secundário à oclusão de um ramo da veia retiniana com a presença de uma membrana epirretiniana.

ABSTRACT

ABSTRACT Purpose: To evaluate vascular density in super­ficial 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.


RESUMO Objetivo: Avaliar a densidade vascular do plexo capilar superficial e profundo da retina, usando angiografia por tomografia de coerência óptica em pacientes com oclusão de ramo da veia central da retina, comparando o olho afetado com o contralateral do mesmo paciente e ambos com olhos normais. Métodos: Estudo transversal. Incluídos dezesseis pacientes com oclusão de ramo da veia central da retina sem tratamento prévio. Pacientes com exames de baixa qualidade, altas ametropias, outras patologias de retina ou coróide foram excluídos. Para comparação, trinta e um pacientes sem doença ocular foram selecionados. Todos foram submetidos a cinco exames angiografia por tomografia de coerência óptica, apenas aqueles com pelo menos dois exames de boa qualidade permaneceram no estudo. Os testes Kruskal-Wallis, Wilcoxon, e Mann-Whitney foram utilizados. Resultados: Densidades vasculares mais baixas do plexo capilar superficial e plexo capilar profundo foram observadas quando olhos com oclusão de ramo da veia central da retina foram comparados com os contralaterais: densidade total (p=0,02 para plexo capilar superficial, p=0,049 para plexo capilar profundo), densidade parafoveal (p=0,02 para plexo capilar superficial, p=0,011 para plexo capilar profundo). Comparando olhos acometidos com olhos normais, também foram observadas densidades vasculares mais baixas de plexo capilar superficial e plexo capilar profundo: densidade total (ambos com p<0,001) e densidade parafoveal (ambos com p<0,001). Quando os olhos contralaterais foram comparados aos normais, tanto a densidade total do plexo capilar superficial e plexo capilar profundo (ambos com p=0,001) quanto a densidade parafoveal (plexo capilar superficial com p=0,001, plexo capilar profundo com p<0,001) foram menores. Ao se realizar uma subanálise, minimizando o fator hipertensão arterial, esta diferença não se manteve. Conclusões: Densidades vasculares mais baixas do plexo capilar superficial e do plexo capilar profundo foram observadas em olhos com oclusão de ramo da veia central da retina. Além disso, a presença de densidades vasculares mais baixas nos olhos contralaterais mostra que já existem altera­ções nesses olhos antes das alterações clínicas, devido a al­terações inicias da retinopatia hipertensiva.

ABSTRACT

ABSTRACT Purpose: To investigate retinal microvasculature changes in patients treated with anti-VEGF for macular edema secondary to branch retinal vein occlusion. Methods: We examined 38 eyes of 19 patients for the study. We measured superficial and deep capillary plexus vessel densities (%), foveal avascular zone areas (mm2), and central macular thicknesses. Results: Parafoveal superficial and deep capillary plexus values were significantly lower in eyes with branch retinal vein occlusion than in fellow eyes (p<0.001). We found a significant increase in parafoveal deep capillary plexus values after the anti-VEGF treatment (p=0.032). The mean foveal avascular zone was larger in eyes with branch retinal vein occlusion than in control eyes (p<0.001). The mean central macular thickness was significantly higher in eyes with branch retinal vein occlusion than in controls, and we observed a significant decrease in central macular thickness after anti-VEGF treatment (<0.001). In addition, the cystic structures in the deep capillary plexus regressed. Conclusion: Optical coherence tomography angiography enables qualitative and quantitative evaluations during follow-up of patients treated for branch retinal vein occlusion.


RESUMO Objetivo: Investigar as alterações na microvascu latura da retina em pacientes tratados com anti-VEGF para ede ma macular secundário à oclusão de ramo da veia retiniana. Métodos: Foram examinados 38 olhos de 19 pacientes para o estudo. Medimos as densidades dos vasos do plexo capilar superficial e profunda (%), áreas da zona avascular foveal (mm2) e espessura macular central. Resultados: Os valores do plexo capilar superficial e profundo parafoveal foram significativamente menores nos olhos com oclusão de ramo da veia retiniana do que nos outros olhos (p<0,001). Encontramos um aumento significativo nos valores de plexo capilar profundo parafoveal após o tratamento com anti-VEGF (p=0,032). A zona avascular foveal média foi maior nos olhos com oclusão de ramo da veia retiniana do que nos olhos controle (p<0,001). A espessura macular central média foi significativamente maior nos olhos com oclusão de ramo da veia retiniana do que nos controles, e observamos uma diminuição significativa na espessura macular central após o tratamento com anti-VEGF (< 0,001). Além disso, as estruturas císticas no plexo capilar profundo regrediram. Conclusão: A angiotomografia de coerência óptica permite avaliações qualitativas e quantitativas durante o acompanhamento de pacientes tratados por oclusão de ramo da veia retiniana.

ABSTRACT

Resumo Objetivo: O tratamento com anti-angiogêncios é uma das modalidades mais utilizadas em patologias relacionadas ao edema macular. A injeção intravítrea de um inibidor do VEGF-A tem alta efetividade, porém está relacionada com efeitos adversos, como o aumento da pressão intraocular. O objetivo deste estudo foi avaliar a variação da pressão intraocular (PIO) em pacientes que se submeteram a injeções intravítreas de ranibizumabe, a variação de acordo com facia e com história de injeções prévias. Métodos: Este foi um estudo um estu-do observacional transversal. Foram incluídos todos os pacientes submetidos a injeções intravítreas com diagnóstico de degeneração macular relacionada à idade exsudativa, oclusão de veia central da retina com edema macular, ou edema macular diabético. A pressão intraocular foi aferida antes da injeção, imediatamente após e 30 minutos após a injeção com tonômetro portátil. Resultados Foram realizadas 143 injeções intravítreas, restando para a análise 96 injeções realizadas em 55 participantes. A comparação entre a PIO antes e 30 minutos após a injeção intravítrea mostrou-se estatisticamente significativa com PIO final maior que a inicial (p<0,0001) em pacientes com edema macular diabético. Pacientes fácicos e afácicos não mostraram diferenças significativas com relação a variação da PIO. Quando analisados apenas os participantes que haviam recebido injeções prévias, não foi encontrado uma variação significativa. Conclusão: Concluímos neste estudo que existe uma diferença significativa entre a pressão intraocular antes e 30 minutos após a injeção intravítrea de ranibizumabe em pacientes com edema macular diabético, mos-trando que esse período de tempo não foi suficiente para a regressão da PIO ao valor pré-injeção. Não encontramos diferenças significativas entre outros grupos, comparação entre fácicos e afácicos, nem em pacientes que haviam recebido injeções prévias.


Abstract Objective: Treatment with anti-angiogenic drugs is one of the most widely used modalities of treatment of macular edema related conditions. Intravitreal injection of a VEGF-A inhibitor is highly effective, but is related to adverse effects such as increased intraocular pressure. The objective of this study was to evaluate intraocular pressure (IOP) variation in patients who underwent intravitreal injections of ranibizumab, variation according to phakic/aphakic and history of previous injections. Methods: This was a cross-sectional observational study. All patients submitted to intravitreal injections with diagnosis of exudative age-related macular degeneration, retinal central vein occlusion with macular ede-ma, or diabetic macular edema were included. The IOP was measured before the injection, immediately after and 30 minutes after the injection with a portable tonometer. Results: 143 intravitreal injections were performed, with 96 injec-tions performed in 55 participants. The comparison between IOP before and 30 minutes after intravitreal injection showed to be statistically significant with higher than initial IOP (p <0.0001) in patients with diabetic macular edema. Phakic and aphakic patients did not show significant differences regarding IOP variation. When only those participants who had received previous injections were analyzed, no significant variation was found. Conclusion: We conclude in this study that there is a significant difference between intraocular pressure before and 30 minutes after intravitreal injection of ranibizumab in patients with diabetic macular edema, showing that this period of time was not sufficient for regression of IOP at the pre-injection value . We did not find significant differences between other groups, comparing phakic and aphakic patients, nor in patients who had received previous injections.

ABSTRACT

ABSTRACT Purpose: The objective of this study was to evaluate subfoveal choroidal thickness (SFCT) using enhanced depth imaging optical coherence tomography (EDI-OCT) in patients with naïve branch retinal vein occlusion (BRVO) before and after intravitreal dexamethasone implant (Ozurdex®) injection. Methods: Thirty-nine patients with unilateral BRVO and 35 healthy subjects were included in this prospective study. Choroidal thickness was evaluated by EDI-OCT at baseline and 1 month after dexamethasone implant. Results: The mean SFCT measured in 39 patients with BRVO was 299.41 ± 55.86 µm, significantly greater than that in contralateral eyes (283.76 ± 57.44 µm; p=0.009) and control eyes (276.14 ± 39.06 µm; p=0.044). The mean SFCT after the treatment was 279.64 ± 50.96 µm, significantly thinner than that before intravitreal dexamethasone therapy (p=0.004). Conclusions: SFCT in treatment-naive BRVO eyes was significantly greater than that in contralateral eyes and healthy eyes and decreased significantly after intravitreal dexamethasone implantation.


RESUMO Objetivo: O objetivo deste estudo foi avaliar a espessura da coróide (SFCT) usando imagens de tomografia de coerência óptica com profundidade aprimorada (EDI-OCT) no tratamento de pacientes com oclusão primária de ramo da veia central da retina (BRVO) antes e após o implante de dexametasona intravítrea (Ozurdex®). Métodos: Trinta e nove pacientes com BRVO unilateral e 35 indivíduos saudáveis foram incluídos neste estudo prospectivo. Espessura da coróide foi avaliada por EDI-OCT na antes e um mês após o tratamento. Resultados: A média da SFCT medida em 39 pacientes com BRVO foi 299,41 ± 55,86 µm, o que foi significativamente maior do que a dos olhos contralaterias (283,76 ± 57,44 µm) e dos olhos controle (276,14 ± 39,06 µm) (p=0,009 e p=0,044, respectivamente). A média da SFCT após o tratamento foi 279,64 ± 50,96 µm, o que foi significativamente menor do que antes do mesmo (p=0,004). Conclusões: A SFCT do tratamento de olhos com BRVO primária foi significativamente maior do que a dos olhos contralaterais e dos olhos saudáveis, e diminuiu significativamente após o implante intravítreo de dexametasona.

ABSTRACT

PURPOSE: To compare pain scores of patients during intravitreal 27-gauge bevacizumab and 30-gauge ranibizumab injection procedures. METHODS: Seventy eyes of 70 patients who had not previously undergone intravitreal anti-vascular endothelial growth factor therapy were included in this study. Thirty-five patients received ranibizumab and 35 patients received bevacizumab. The diagnoses of the patients were: 27 age related macular degeneration, 15 diabetic macular edema, 9 diabetic vitreous hemorrhage, 6 central retinal vein occlusion, 11 branch retinal vein occlusion and 2 central serous chorioretinopathy. Bevacizumab (1.25 mg/0.05 mL) was injected into the vitreous cavity using a 27-gauge needle, and ranibizumab (0.5 mg/0.05 mL) was injected with 30-gauge needle. Patients were asked just after the injection to rate their perceived pain during the injection using the visual analogue scale (VAS) of 0 (no pain) to 10 (unbearable/worst pain). The average of these scores was used as the primary outcome. RESULTS: The VAS pain scores in the ranibizumab and bevacizumab groups were 1.06 +/- 0.91 (range, 0 to 3) and 1.94 +/- 1.55 (range, 0 to 7), respectively, a significant difference (p = 0.005). Patients or =65 years of age in both the ranibizumab and bevacizumab groups were then compared. For patients or =65 years, there was not a significant difference in the average VAS pain scores between groups (p = 0.238). Female and male patients in both ranibizumab and bevacizumab groups were also compared. For female patients, there was a significant difference in the average VAS pain scores between groups (p = 0.016), although not for male patients (p = 0.078). CONCLUSIONS: Thirty-gauge intravitreal injection is more comfortable than 27-gauge injection. Injection of bevacizumab with 30-gauge needle syringes may be more tolerable for patients.

ABSTRACT

This case describes the reversal of early central retinal vein occlusion (CRVO) with disc swelling after intravitreal dexamethasone implant (Ozurdex) injection. A 44-year-old female presented with sudden-onset intermittent blurred vision in her left eye. Fundus examination revealed multiple retinal hemorrhages without macular edema (ME). Two weeks later, an increased number of retinal hemorrhages with severe disc swelling were noted with still no sign of ME. An intravitreal dexamethasone implant was injected. Five days later, there were improvements in disc swelling and retinal hemorrhage. One month later, her subjective visual symptoms were completely improved, and fundus examination revealed marked improvement along with almost complete resolution of disc swelling. Intravitreal dexamethasone implant injection may potentially change the natural course of CRVO progression and its various subsequent complications.
