ABSTRACT
ABSTRACT

Purpose:

Polycystic ovary syndrome (PCOS) is an endocrine disease characterized by chronic anovulation and hyperandrogenism. Hormonal changes can affect tear function. This study evaluates tear function and impact of hyperandrogenism on it in PCOS patients.

Methods:

Fifty patients with PCOS and thirty control volunteers were examined for tear break-up time, Schirmer-I and tear osmolarity. Also, serum levels of total testosterone, FSH, LH and AMH were determined in venous blood samples in the early follicular phase. PCOS patients were divided into two groups by plasma total testosterone level Group A with normal (≤0.513 ng/ml;n=27), Group B with higher hormone level (>0.513 ng/ml;n=23). Healthy control group indicated as Group C (n=30).

Results:

LH, total testosterone levels were higher in the PCOS group than in the control group (p=0.012; p=0.025). Mean values of tear break-up time and Schirmer-I were different between groups and especially Group A and C were near to each other differing from B (p>0.05). Tear osmolarity results were higher in Group B, compared to A and C (p=0.049; p=0.033). No significant difference detected in tear osmolarity value means of Group A and C (p=0.107). AMH levels were higher in Group B, compared to A and C (p=0.002; p=0.001). AMH levels in Group A were higher than that of C (p=0.002). Positive correlation between levels of total testosterone and AMH was detected in all PCOS patients (n=50;Pearson's r=0.579; p<0.001).

Conclusion:

Tear function can be affected in PCOS patients with hyperandrogenism. Tear osmolarity is the most sensitive and objective assessment method for ocular surface changes in PCOS.
RESUMO
RESUMO

Objetivo:

A síndrome do ovário policístico (SOP) é uma doença endócrina caracterizada por anovulação crônica e hiperandrogenismo. As alterações hormonais podem afetar a função cardíaca. Este estudo avalia a função lacrimal e o impacto do hiperandrogenismo sobre ela em pacientes com SOP.

Métodos:

Cinquenta pacientes com SOP e trinta voluntárias de controle foram examinadas para tempo de ruptura lacrimal, Schirmer-I e osmolaridade lacrimal. Além disso, os níveis séricos de testosterona total, FSH, LH e HAM foram determinados em amostras de sangue venoso na fase folicular precoce.As pacientes com SOP foram divididas em dois grupos por nível de testosterona plasmática total Grupo A com nível normal (≤0.513 ng/ml; n = 27), Grupo B com nível superior de hormônio (> 0,513 ng/ml; n = 23). Grupo de controle saudável indicado como Grupo C (n = 30).

Resultados:

Os níveis de LH e testosterona total foram maiores no grupo com SOP do que no grupo controle (p = 0,012; p = 0,025). Os valores médios de tempo de ruptura lacrimal e Schirmer-I foram diferentes entre os grupos, e especialmente os Grupos A e C estavam próximos um do outro, diferente do B (p > 0,05). Os resultados de osmolaridade lacrimal foram maiores no Grupo B, em comparação com A e C (p = 0,049; p = 0,033). Não houve diferença significativa detectada em valor médio de osmolaridade lacrimal nos Grupos A e C (p = 0,107). Os níveis de HAM foram maiores no Grupo B, em comparação com A e C (p = 0,002; p = 0,001). Os níveis de AMH no Grupo A foram superiores aos de C (p = 0,002). Uma correlação positiva entre os níveis de testosterona total e AMH foi detectada em todas as pacientes com SOP (n = 50; Pearson's r = 0,579; p < 0,001).

Conclusão:

a função lacrimal pode ser afetada em pacientes com SOP com hiperandrogenismo. A osmolaridade lacrimal é o método de avaliação mais sensível e objetivo para alterações da superfície ocular em SOP.
