RESUMO
Objetivo:
Investigar a associação entre glaucoma primário de ângulo aberto (GP AA) e hipotireoidismo.
Métodos:
No primeiro estudo, 15 pacientes com hipotireoidismo primário que não estavam recebendo complementação hormonal foram investigados quanto à presença de GPA A. No segundo estudo, 65 pacientes com GPAA foram investigados quanto à ocorrência de hipotireoidismo através da dosagem de TSH.
Resultados:
Nenhum dos 15 pacientes com hipotireoidismo apresentou dados compatíveis com o diagnóstico de GPA A, e o nível médio da pressão intraocular nesses pacientes foi de 15,8 ± 2,3 mmHg, variando entre 11 e 21 mmHg. Apenas um (1,5%) entre os 65 pacientes glaucomatosos apresentou hipotireoidismo subclínico, diagnosticado graças aos níveis elevados de TSH.
Conclusão:
Os achados deste estudo não confirmam a hipótese de uma associação entre hipotireoidismo e GPAA.

SUMMARY
Purpose:
To investigate the association between primary open-angle glaucoma (POAG) and hypothyroidism.
Methods:
In the first study, 15 patients with hypothyroidism were analyzed to verify the presence of POAG. In the second study, a TSH assay was employed as a screening test to determine the incidence of hypothyroidism in 65 patients with POAG.
Results:
None of the 15 patients with hypothyroidism had clinical findings compatible with POAG, and the mean intraocular pressure measurements were 15.8 ± 2.3 mmHg (range 11 to 21 mmHg). Only one (1.5%) of the 65 POAG patients showed abnormal TSH levels, and was diagnosed as having subclinical hypothyroidsm.
Conclusion:
These findings do not support the existence of a positive correlation between hypothyroidism and POAG.
Key words:
