Effect of cataract surgery on postoperative macular edema in patients with diabetic macular edema

Abstract

Aim: The aim of this study is to investigate the changes and effect of hemoglobin A_1c in patients with diabetic macular edema following cataract surgery.

 Material and Methods: This retrospective clinical study included 30 eyes of 30 patients with diabetic macular edema who underwent phacoemulsification cataract surgery. Ophthalmological examination and optical coherence tomography evaluation of macula were performed at firstweek and first and third months.

 Results: Compared to baseline, best corrected visual acuity improved significantly at first and third month’s visits (P ˂ 0.05). In terms of foveal thickness, it was increased significantly at first and third months (P ˂ 0.05) and decreased by the end of first month. There was a positive correlation between hemoglobin A_1c levels and foveal thickness (P = 0.030, r =0.38).

 Conclusion: Patients with diabetic macular edema and cataract seem to benefit from phacoemulsification surgery. They should be followed for postoperative macular edema with optical coherence tomography, particularly during the first six month.

 Key words: Diabetic macula edema, phacoemulsification, optical coherence tomography

 

Diabetik makula ödemi olan hastalarda katarakt cerrahisinin postoperatif makula ödemine etkisi

Abstract

Amaç: Diyabetik makula ödemi olan hastalarda katarakt cerrahisi sonrası makula ödemindeki değişikliklerin ve hemoglobin A_1C  (HbA_1C) ile ilişkisinin incelenmesi.

Gereç ve Yöntemler: Bu retrospektif klinik çalışma diyabetik makula ödemi olan ve komplikasyonsuz fakoemülsifikasyon ameliyatı uygulanan 30 hastanın 30 gözünü kapsamaktadır. Olgulara operasyon öncesi ve sonrası 1. hafta 1. ay ve 3. aylarda oftalmolojik muayene yapıldı ve optik koherens tomografi (OKT) yardımıyla santral foveal kalınlık ölçümü yapıldı.

Bulgular: Başlangıç değerlerine göre en iyi düzeltilmiş görme keskinliği bakımından 1. ve 3. ay değerleri artma gösterdi ve bu farklılık istatistiksel olarak anlamlıydı (P ˂ 0.05). Foveal kalınlık bakımından da 1. ay ve 3. ay değerleri başlangıca göre istatistiksel olarak anlamlı derecede yüksek bulundu. Ancak 1 aydan sonra artma eğilimi azaldı. HbA_1C ile ilk ay foveal kalınlık arasında anlamlı pozitif bir korelasyon bulundu. (P =  0.030,  r = 0 .38)

Sonuçlar: Diyabetik makula ödemi ve kataraktı olan hastalar fakoemülsifikasyonla katarakt cerrahisinden fayda görmektedir. Katarakt cerrahisi sonrası makula ödemi açısından özellikle ilk 6 ay OKT ile düzenli takip yapılmalıdır.
