Intraocular pressure rise following pars plana vitrectomy

Objective & Hypothesis:Purpose: In this study,we evaluated the frequency of intraocular pressure (IOP) rise following pars plana vitrectomy(PPV), the mechanisms and its relationship with the applied surgical procedure.

📊

Key Findings & Data:Materials and Methods: Seventysix eyes of 76 patiens, which had PPV between June 2001 and August 2002 were evaluated prospectively for the IOP rise mechanisms and factors that affect this rise.

💡

Conclusion & Impact:Lensectomy and silicone oil tamponade are more effective on IOP rise, by various mechanisms.

Abstract

Purpose: In this study,we evaluated the frequency of intraocular pressure (IOP) rise following pars plana vitrectomy(PPV), the mechanisms and its relationship with the applied surgical procedure. Materials and Methods: Seventysix eyes of 76 patiens, which had PPV between June 2001 and August 2002 were evaluated prospectively for the IOP rise mechanisms and factors that affect this rise. Results: Mean IOP was 12.19 ± 5.53 preoperatively, 20.34 ± 12.20 on the postoperative 1 st day, 14.62 ± 7.05 on the postoperative 1 st month and 14.51 ± 6.41 on the postoperative 6th month. The difference between the IOP on the postoperative 1 st day,1 st month,and 6th month was found to be statistically significant. Statistically significant relationship between phakia and open angle glaucoma development was also detected. Also the relation of lensectomy and silicone oil tamponade with pupillary blockage glaucoma was statistically significant. Conclusion: Following vitrectomy, IOP rise can be seen. Lensectomy and silicone oil tamponade are more effective on IOP rise, by various mechanisms.

Özet

Amaç: Bu çalışmada Pars Plana Vitrektomi(PPV) sonrası göz içi basınç(GİB) artış sıklığı, mekanizmaları ve uygulanan cerrahi yöntemle ilişkisi değerlendirilmeye çalışılmıştır. Gereç ve Yöntem: Haziran 2001 ile Ağustos 2002 tarihleri arasında, hastanemizin 2.Göz kliniğinde PPV uygulanan 76 hastanın 76 gözü prospektif olarak GİB artış mekanizmaları ve bu artışı etkileyen faktörler açısından değerlendirildi. Bulgular: Hastaların cerrahi girişim öncesi GİB'ı ortalama 12.19 ± 5.53, cerrahi girişim sonrası 1. günde GİB'ı ortalama 20.34 ± 12.20, cerrahi girişim sonrası 1. ay GİB'ı ortalama 14.62 ± 7.05 ve 6.ay GİB'ı ortalama 14.51 ± 6.41 olup cerrahi girişim öncesi GİB'ı ile cerrahi girişim sonrası 1.gün, 1.ay ve 6.ay GİB'ı arasındaki fark istatistiksel olarak anlamlı bulundu. Fakik olma ile açık açılı glokom gelişmesi; lensektomi yapılması ve silikon tamponad kullanılması ile pupil bloğu glokomu gelişmesi arasında istatistiksel olarak anlamlı derecede bir ilişki saptanmıştır. Sonuç: Vitrektomi sonrası GİB artışı görülebilmektedir. Lensektomi yapılması ve silikon tamponad kullanılması çeşitli mekanizmalar aracılığıyla GİB artışı üzerinde daha etkili olmaktadır.
