ABSTRACT
ABSTRACT

Purpose:

To investigate the effect of pseudoex foliation syndrome on choroidal thickness as compared with healthy individuals and subjects with primary open-angle glaucoma.

Methods:

This prospective, randomized study included 30 primary open angle glaucoma patients and 30 pseudoexfoliation glaucoma patients with similar demographic characteristics and 30 eyes of 30 healthy individuals comprised the control group. Regular optic nerve and macular images were obtained using a Cirrus HD spectral domain optical coherence tomography instrument, along with macular choroidal thickness measurements with enhanced depth imaging mode.

Results:

Age, sex, and axial length values were similar among the three groups (p>0.05). The primary open angle glaucoma and pseudoexfoliation glaucoma groups had comparable levels of glaucomatous damage. The mean subfoveal choroidal thickness values in the primary open angle glaucoma, pseudoexfoliation glaucoma, and control groups were 271.80 ± 19.96 μm, 241.43 ± 32.47 μm, and 268.03 ± 24.50 μm, respectively. The pseudoexfoliation glaucoma group had the lowest choroidal thickness values of the three groups (p values pseudoexfoliation-control 0.001; pseudoexfoliation-primary open angle glaucoma <0.001, primary open angle glaucoma-control 0.516, independent samples t-test).

Conclusion:

The macular choroid was thinner in patients with pseudoexfoliation glaucoma, as compared with both healthy individuals and open-angle glaucoma patients with similar degrees of glaucomatous damage.
RESUMO
RESUMO

Objetivo:

Investigar o efeito do glaucoma pseudoexfoliativo sobre a espessura da coroide em comparação com indivíduos saudáveis e com glaucoma primário de ângulo aberto.

Métodos:

Este estudo prospectivo e randomizado incluiu 30 pacientes com glaucoma primário de ângulo aberto e 30 com glaucoma pseudoexfoliativo, com características demográficas semelhantes e 30 olhos de 30 indivíduos saudáveis compuseram o grupo controle. Imagens da área macular e do nervo óptico foram obtidas usando um tomógrafo por coerência óptica no domínio espectral do modelo Cirrus HD, juntamente com medições da espessura da coroide na área macular através do modo de imagem de profundidade realçada.

Resultados:

Os valores de idade, sexo e comprimento axial foram semelhantes nos três grupos (p>0,05). Os grupos de glaucoma primário de ângulo aberto e de glaucoma pseudoexfoliativo tinham níveis comparáveis de lesões glaucomatosas. Os valores médios da espessura subfoveal da coroide nos grupos do glaucoma primário de ângulo aberto, glaucoma pseudoexfoliativo e de controle foram 271,80 ± 19,96 μm, 241,43 ± 32,47 μm e 268,03 ± 24,50 μm, respectivamente. O grupo glaucoma pseudoexfoliativo apresentou os menores valores de espessura de coroide dos três grupos (valores de p pseudoexfoliativo-controle 0,001; pseudoexfoliativo-glaucoma primário de ângulo aberto <0,001, controle de glaucoma primário de ângulo aberto 0,516; teste de t de amostras independentes).

Conclusão:

A coroide na área macular era mais fina em pacientes com glaucoma pseudoexfoliativo, quando comparada com indivíduos saudáveis e pacientes com glaucoma de ângulo aberto com graus similares de lesão glaucomatosa.
