ABSTRACT
ABSTRACT

Purpose:

Optic coherence tomography (OCT) evaluation of the choroid, retina, and retinal nerve fiber layer after uncomplicated yttrium-aluminum-garnet (YAG) laser capsulotomy.

Methods:

OCT analysis of retinal and choroidal structures was performed in 28 eyes of 28 patients following routine examinations before and 24 h, 72 h, 2 weeks, 4 weeks, and 12 weeks after YAG laser capsulotomy. Data were analyzed using the SPSS software.

Results:

Data collected before YAG capsulotomy and at the above mentioned follow-up visits are summarized as follows. Mean central subfoveal choroidal thickness before YAG capsulotomy was 275.85 ± 74.78 µm; it was 278.46 ± 83.46 µm, 283.39 ± 82.84 µm, 280.00 ± 77.16 µm, 278.37 ± 76.95 µm, and 278.67 ± 76.20 µm after YAG capsulotomy, respectively. Central macular thickness was 272.14 ± 25.76 µm before YAG capsulotomy; it was 266.53 ± 26.47 µm, 269.14 ± 27.20 µm, 272.17 ± 26.97 µm, 270.91 ± 26.79 µm, and 273 ± 26.63 µm after YAG capsulotomy, respectively. Mean retinal nerve fiber layer thickness before YAG was 99.89 ± 7.61 µm; it was 98.50 ± 8.62 µm, 98.14 ± 8.69 µm, 99.60 ± 8.39 µm, 99.60 ± 8.39 µm, and 99.60 ± 8.35 µm after YAG capsulotomy, respectively. No observed change was statistically significant. No significant changes were observed with regard to mean intraocular pressure.

Conclusions:

After YAG laser capsulotomy, no statistically significant changes were found in choroidal, retinal, and optical nerve fiber layer thicknesses, although slight thickness changes in these structures were observed, particularly during the first days.
RESUMO
RESUMO

Objetivo:

Avaliação da coroide, retina e a camada de fibras nervosas da retina por meio de tomografia de coerência óptica (OCT) após capsulotomia por YAG laser não complicada.

Método:

Vinte e oito olhos de 28 pacientes foram incluídos neste estudo. Estruturas da retina e coroide foram analisados usando ACT nos exames de rotina antes da capsulotomia posterior por YAG laser e 24 horas, 72 horas, 2 semanas, 4 semanas e 12 semanas após YAG. Os resultados foram avaliados através do programa SPSS.

Resultados:

Os resultados deste estudo, pré YAG e às visitas de acompanhamento acima, podem ser resumidos da seguinte forma. A espessura média de coroide subfoveal central antes do YAG foi 275,85 ± 74,78 m; após YAG foi 278,46 ± 83,46 µm, 283,39 ± 82,84 µm, 280,00 ± 77,16 µm, 278,37 ± 76,95 µm, e 278,67 ± 76,20 µm, respectivamente. A espessura macular central foi 272,14 ± 25,76 mm antes YAG; e 266,53 ± 26,47 µm, 269,14 ± 27,20 µm, 272,17 ± 26,97 µm, 270,91 ± 26,79 µm, e 273 ± 26,63 µm, respectivamente. Espessura média da camada de fibras nervosas da retina antes do YAG foi 99,89 ± 7,61 mm; e 98,50 ± 8,62 µm, 98,14 ± 8,69 µm, 99,60 ± 8,39 µm, de 99,60 ± 8,39 µm, 99,60 ± 8,35 µm, respectivamente. Nenhuma das alterações observadas foram estatisticamente significativas. As médias da pressão intraocular, também não mostraram alterações significativas.

Conclusões:

Não houve mudanças significativas foram encontradas na coroide, camada de fibras nervosas da retina espessuras e ópticos, após a capsulotomia por YAG laser, embora houvesse, especialmente nos primeiros dias, discretas alterações de espessura nas estruturas mencionadas.
