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
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.
