Fakik ve Psödofakik Hastalarda Pars Plana Vitrektomi Sonrası Ön kamara Derinliği ve Santral Kornea Kalınlığı Değişiklikleri

Anterior Chamber Depth and Central Corneal Thickness Changes After Pars Plana Vitrectomy in Phakic and Psedophakic Patients

Özet

Amaç: Pars plana vitrektomi (PPV) sonrası ön kamara derinliği (ÖKD) ve santral kornea kalınlığı (SSK) değişikliklerini incelemek.Gereç ve yöntem: Endotamponat kullanılmadan, komplikasyonsuz, 23 gauge (G) PPV uygulanan toplam 64 kişinin 64 gözü çalışmaya dahil edildi. Grup I, 32 fakik hasta; Grup II, 32 psödofakik hastadan oluştu. Optik biyometri kullanarak ÖKD ve SKK değerleri ameliyat öncesi ile PPV ameliyatı sonrası 1. ve 6. aylarda ölçüldü.Bulgular: Grup I'de ortalama ÖKD ameliyat öncesi 2.82±0.41mm, ameliyat sonrası 1. ayda 2.72±0.37 mm; 6. ayda 2.61± 0.35 mm idi. Grup II'de ortalama ÖKD ameliyat öncesi 3.53±0.25 mm, ameliyat sonrası 1. ayda 3.51±0.31 mm; 6. ayda 3.39± 0.27 mm idi. Her iki grupda da ameliyat öncesine göre ameliyat sonrası 1.ay ve 6.ayda ÖKD değerinde anlamlı azalma vardı (p 0.05). Sonuç: Komplikasyonsuz, 23 G PPV sonrası 1. ay ve 6. ay ölçümlerinde, ameliyat öncesine göre, ÖKD'nin azaldığı ve SSK'nın anlamlı olarak değişmediği görüldü. Daha kesin sonuçlar için ileri çalışmalara ihtiyaç vardır.

Abstract

Purpose: To evaluate the changes in anterior chamber depth (ACD) and central corneal thickness (CCT) after pars plana vitrectomy (PPV).Materials and methods: A total of 64 eyes of 64 patients having 23 gauge (G) PPV without endotamponate were enrolled in this study. Group I consisted of 32 phakic patients and Group II consisted of 32 pseudophakic patients. By using an optical biometry approach, ACD and CCT values were measured preoperative as well as postoperative 1st and 6th months following uncomplicated PPV. Results: In Group I, mean preoperative ACD was 2.82±0.41mm, mean postoperative 1st month ACD was 2.72±0.37 mm; mean postoperative 6th month ACD was 2.61± 0.35 mm. In Group II, mean preoperative ACD was 3.53±0.25 mm, whereas the mean postoperative 1st month and 6th month ACD values were 3.51±0.31 mm and 3.39± 0.27 mm, respectively. In both groups; decrease in ACD measurements were signifi cant at postoperative 1st month and 6th months with respect to preoperative ACD (p<0.05). Group II had higher ACD values at each measurement time (p<0.05). In both groups, there was not a signifi cant change of CCT in preoperative, postoperative 1 and 6 months measurements (p>0.05). There was not a signifi cant CCT difference between two groups at each measurement time (p>0.05).Conclusion: ACD measurements decreased and CCT measurements did not change signifi cantly at the 1st and 6th months measurements with respect to the preoperative measurements. But further studies are required for more information.
