Combined pars plana vitrectomy (PPV) and phacoemulsification (phaco) versus PPV and deferred phaco for phakic patients with full-thickness macular hole (FTMH) and no significant cataract at baseline: 1-year outcomes of a randomized trial combined PPV/phaco vs PPV/deferred phaco for MH.

PURPOSE: To compare functional and anatomic outcomes of combined pars plana vitrectomy (PPV) and phacoemulsification (phaco) versus PPV and deferred phaco in patients with full-thickness macular hole (FTMH) and no significant cataract. METHODS: Thirty-four patients were randomized to group 1 (combined PPV/phaco) and 34 to group 2 (PPV/deferred phaco). Group 2 patients could undergo phaco any time after FTMH surgery if significant cataract developed. RESULTS: Sixty-five patients (33 group 1 and 32 group 2) completed the 12-month visit. Mean ± SEM logMAR best-corrected visual acuity (BCVA) was 0.92 ± 0.04 and 0.90 ± 0.04 at baseline and improved significantly to 0.60 ± 0.05 and 0.58 ± 0.05 at month 12 (p < 0.0001) in groups 1 and 2, respectively. There was no significant difference between the groups in mean BCVA at baseline or at month 12. Mean macular sensitivity (dB) was 18.22 ± 0.93 and 16.72 ± 0.93 at baseline and increased to 21.13 ± 0.86 and 21.07 ± 0.85 in groups 1 and 2, respectively (p < 0.05) with no significant difference between the groups (p = 0.449) at month 12. FTMH closure rate was 73% and 75% in groups 1 and 2, respectively (p = 0.834). CONCLUSION: Among patients with FTMH and no significant cataract at baseline, combined PPV/phaco was associated with similar BCVA, microperimetry, and FTMH closure outcomes at 1-year compared with PPV/deferred phaco.

Choroidal nevus and polypoidal vasculopathy: case series.

BACKGROUND: To report an association between choroidal nevus and polypoidal choroidal vasculopathy (PCV) in three patients. CASE PRESENTATION: We have encountered 3 isolated patients in our center presenting with subretinal exudation and a choroidal nevus that were thoroughly evaluated by slit lamp biomicroscopy, fundus photos, Fluorescein angiography (FA), indocyanine green angiography (ICG), B-scan ultrasound, and optical coherence tomography (SD-OCT-Heidelberg). The classic features of choroidal neovascularization seen on PVC were present in all 3 patients, all of whom had a substantial response to intravitreous antiangiogenic agent. OCT, Fluorescein and ICG Angiography, and Fundus autofluorescence (FAF) revealed similar findings in all cases. DISCUSSION AND CONCLUSIONS: We have identified a clinical pattern of PCV and choroidal nevus that can be diagnosed early using fluorescein angiography, ICG and OCT.

Multimodal assessment of patients with chronic central serous chorioretinopathy.

PURPOSE: To examine differences between fluorescein angiography (FA) and indocyanine green angiography (ICG) findings in patients with chronic central serous chorioretinopathy (CSC), comparing these with optical coherence tomography (OCT) findings. METHODS: Ten consecutive patients with chronic CSC (19 eyes; 7 men; mean age, 50.7 ± 8.4 years) underwent multimodal evaluation that included FA, ICG, and OCT (Spectralis HRA-OCT, Heidelberg Engineering, Heidelberg, Germany). Changes such as hyperfluorescence (caused by increased transmission of the normal choroidal fluorescence, staining, or "pooling") and hypofluorescence (caused by a blockage or vascular filling defect) were evaluated in the early (4 min), middle (4-8 min) and late (>8 min) angiography phases and compared to OCT findings. RESULTS: Bilateral disease was present in nine of the 10 patients. Areas of discontinuation or attenuation of the hyporeflective layer of the retinal pigment epithelium (RPE) on OCT were observed at the same locations as hyperfluorescent angiography window defects on FA and ICG within examination phases. In areas of serous or RPE detachment, the hyperfluorescence pattern was similar on FA and ICG. However, ICG demonstrated areas of hyperfluorescence secondary to choriocapillaris hyperpermeability, with no corresponding change on FA in 12 (70%) of the 19 eyes. This finding was more evident in the middle and late phases of the examinations and there was no evident change in retinal architecture on OCT in these hyperpermeable choroidal regions. CONCLUSION: In patients with chronic CSC, ICG may reveal choroidal abnormalities that are not evident on FA. This finding may help optimize the monitoring and treatment of CSC.

Structure-functional correlation using adaptive optics, OCT, and microperimetry in a case of occult macular dystrophy.

We report retinal functional and structural changes of a 40-year-old man diagnosed with occult macular dystrophy. Comprehensive ophthalmological evaluation was performed, followed by spectral-domain optical coherence tomography (SD-OC - Heidelberg) and image acquisition using an adaptive optics (AO) camera (RTX1, Imagine Eyes) for photoreceptor density analysis. Functional tests included full-field ERG (ERG) and multifocal electroretinography (mfERG) (Diagnosys, LLC) and microperimetry with scanning laser ophthalmoscope (SLO) fixation controlled (MAIA, CenterVUE). OCT revealed a line of discontinuity corresponding to cone outer-segment photoreceptors associated with a loss of cone density, highlighted by a dark blue spot on the AO co ne-density map on the fovea in both eyes. Loss of central sensitivity was revealed using microperimetry; ERG was within the normal range, although the mfERG showed a reduced central response amplitude.

RESUMO Relatamos exames de função e estrutura retiniana de paciente masculino, de 40 anos, com diagnóstico clínico de Distrofia Macular Oculta (DMO). Avaliação oftalmológica completa foi seguida por tomografia de Coerência Óptica (SD-OCT - Heidelberg) e exame com câmara de fundo de olho com tecnologia "Adaptive Optics" (AO - RTX1, Imagine Eyes) para análise da densidade de fotorreceptores. Os exames funcionais incluíram: Eletroretinografia de campo total (ERG) e multifocal (mfERG) (Diagnosys - LLC) e microperimetria com controle de fixação (MAIA - CenterVUE). Os exames revelam descontinuidade da camada de fotorreceptores na região central da fóvea em ambos os olhos pelo SD-OCT em associação com perda de densidade no mosaico cones, representado por mancha azulada no mapa do AO. Os exames de função apresentam diminuição da acuidade visual (20/80; 20/50), redução de sensibilidade central na microperimetria. Como esperado, o ERG está dentro da normalidade, mas há redução da amplitude das respostas centrais do mfERG em ambos os olhos.

Multimodal assessment of patients with chronic central serous chorioretinopathy / Avaliação multimodal em pacientes com coriorretinopatia serosa central crônica

ABSTRACT Purpose: To examine differences between fluorescein angiography (FA) and indocyanine green angiography (ICG) findings in patients with chronic central serous chorioretinopathy (CSC), comparing these with optical coherence tomography (OCT) findings. Methods: Ten consecutive patients with chronic CSC (19 eyes; 7 men; mean age, 50.7 ± 8.4 years) underwent multimodal evaluation that included FA, ICG, and OCT (Spectralis HRA-OCT, Heidelberg Engineering, Heidelberg, Germany).

RESUMO Objetivo: Descrever as diferenças de achados entre a angiofluoresceinografia (FA) e a angiografia digital com indocianina verde (ICG) em pacientes com coriorretinopatia serosa central crônica (CSC), incluindo imagens de tomografia de coerência óptica (OCT). Métodos: Série de casos em que 10 pacientes consecutivos com CSC crônica submetidos à avaliação multimodal, que incluiu FA, ICG e OCT (Spectralis HRA-OCT, Heidelberg Engineering, Heidelberg; Germany). Os pacientes foram avaliados quanto às mudanças como hiperfluorescências (causadas por aumento da transmissão da fluorescência coroidal normal, impregnação ou "pooling") e hipofluorescências (causadas pelo bloqueio ou defeito de enchimento vascular) nas fases precoce (4 minutos), intermediárias (4-8 minutos) e tardias (acima de 8 minutos) da angiografia e comparadas aos achados de OCT. Resultados: Sete dos 10 pacientes (19 olhos) eram homens, média (± DP) de idade dos pacientes foi de 50,7 ± 8,4 anos, e doença bilateral estava presente em nove dos 10 pacientes. Áreas de descontinuação ou atenuação da camada do epitélio pigmentado da retina (EPR), hiporreflectivas no OCT e hiperfluorescência por defeito em janela na FA e ICG ocorreram em locais coincidentes durante as mesmas fases do exame. Em áreas de descolamento seroso ou do EPR, o padrão de hiperfluorescência também foi semelhante em relação à FA e à ICG. No entanto, a ICG demonstrou áreas de hiperfluorescência secundária a hiperpermeabilidade coriocapilar sem mudança correspondente na FA em 12(70%) dos 19 olhos. Este achado da ICG ficou mais evidente nas fases precoces e intermediárias dos exames e não houve mudança evidente na arquitetura da retina no OCT nessas regiões de alteração de hiperpermeabilidade da coroide. Conclusão: Em pacientes com CSC crônica, a ICG pode revelar anormalidades da coróide não evidentes na FA. Esta informação pode ajudar a aperfeiçoar o moni to ramento e tratamento da CSC.
