ABSTRACT
ABSTRACT

Purpose:

Beta-thalassemia minor, a common hereditary blood disorder in Mediterranean countries such as Turkey, is associated with insulin resistance. Insulin resistance, in turn, can be associated with excessively high intraocular pressure and, therefore, intraocular pressure-induced blindness. This study aimed to investigate the intraocular pressure in subjects with beta-thalassemia minor.

Methods:

We conducted a cross-sectional study comprising of 203 subjects divided into two groups beta-thalassemia minor (103) and healthy (100).Hemoglobin electrophoresis was performed and complete blood count, blood pressures, serum fasting glucose and insulin levels were measured. All subjects underwent ophthalmological examinations including intraocular pressure measurements.

Results:

Intraocular pressure in the subjects with beta-thalassemia minor was significantly lower than that in healthy subjects (p=0.007). Additionally, intraocular pressure was inversely correlated with hemoglobin A2 levels (p=0.001, r=-0.320). Serum insulin and systolic blood pressure were significantly higher in subjects with beta-thalassemia minor (p=0.03, p=0.009, respectively).

Conclusion:

Subjects with beta-thalassemia minor had lower intraocular pressure than healthy controls, suggesting beta-thalassemia minor may actually protect against high intraocular pressure.
RESUMO
RESUMO

Objetivo:

Beta-talassemia menor é uma doença hereditária comum no sangue em países mediterrâneos como a Turquia e está associada à resistência à insulina. A resistência à insulina por sua vez, pode estar associada à pressão intraocular excessivamente alta e, portanto à cegueira induzida pela pressão intraocular. Este estudo teve como objetivo investigar a pressão intraocular em indivíduos com beta-talassemia menor.

Métodos:

Foi realizado um estudo transversal compreendendo 203 indivíduos divididos em 2 grupos beta-talassemia menor (103) e saudável (100). Eletroforese de hemoglobina foi realizada e hemograma completo, pressão arterial, glicemia em jejum e níveis de insulina medidos. Todos os indivíduos foram submetidos foram submetidos a exames oftalmológicos, incluindo medidas de pressão intraocular.

Resultados:

A pressão intraocular nos indivíduos com beta-talassemia menor foi significativamente menor do que em indivíduos saudáveis (p=0,007). Além disso, a pressão intraocular foi inversamente correlacionada com os níveis de hemoglobina A2 (p=0,001, r=-0,320). Insulina sérica e pressão arterial sistólica foram significativamente maiores em indivíduos com beta-talassemia menor (p=0,03, p=0,009, respectivamente).

Conclusão:

Os indivíduos com beta-talassemia menor tiveram pressão intraocular menor do que os controles saudáveis, sugerindo que a beta-talassemia menor pode, na verdade, proteger contra a alta pressão intraocular.
