📌 3 Key Takeaways

🎯
Objective & Hypothesis:Aim: To analyze changes in corneal biomechanical properties during the whole course of menstrual cycle Material and Method: Corneal hysteresis (CH), corneal resistance factor (CRF), Goldmann-correlated and corneal-compensated intraocular pressures (IOPg, IOPcc) of right eyes of 19 healthy women were measured by Reichert Ocular Response Analyzer every other day.
📊
Key Findings & Data:Results: Mean CH displayed peaks at 11th and 19th days, which closely paralleled bimodal nature of plasma estrogen.
💡
Conclusion & Impact:Further experimental and clinical studies are needed to analyze the mechanism of these changes and their clinical significance

Abstract

Aim: To analyze changes in corneal biomechanical properties during the whole course of menstrual cycle Material and Method: Corneal hysteresis (CH), corneal resistance factor (CRF), Goldmann-correlated and corneal-compensated intraocular pressures (IOPg, IOPcc) of right eyes of 19 healthy women were measured by Reichert Ocular Response Analyzer every other day. Results: Mean CH displayed peaks at 11th and 19th days, which closely paralleled bimodal nature of plasma estrogen. Mean CRF increased progressively during menstrual cycle. Mean IOPg and IOPcc decreased coincident with peaks in plasma estrogen levels. Conclusions: The observed changes in corneal biomechanical properties could be secondary to hormonal influences. Further experimental and clinical studies are needed to analyze the mechanism of these changes and their clinical significance

Özet

Amaç: Tüm menstruasyon siklusu boyunca korneanın biyomekanik özelliklerinin değişimlerini incelemek. Gereç ve Yöntem: Ondokuz sağlıklı kadın olguda kornea histerezisi (KH), kornea direnç faktörü (KDF), Goldmann-korele ve kornea-kompanzasyonlu göz içi basınçları (sırasıyla GİBg, GİBkk), bir menstruasyon siklusu boyunca Reichert Ocular Response Analyzer ile gün aşırı olarak ölçüldü. Bulgular: Ortalama KH, östrojenin bimodal seyrine uygun olarak 11. ve 19. günlerde zirve değerine ulaştı. Ortalama KDF menstruasyon siklusu boyunca ilerleyici olarak arttı. Ortalama GİBg ve GİBkk, tahmini plazma östrojen seviyesi zirvelerine denk gelecek şekilde azaldı. Sonuç: Korneanın biyomekanik özelliklerinde gözlenen değişiklikler, hormonal etkilere sekonder olabilir. Bu değişikliklerin mekanizmasını ve klinik önemlerini incelemek için daha ileri deneysel ve klinik çalışmalara ihtiyaç vardır
