Abstract

Purpose: To compare the intraocular pressure (IOP) lowering effect and adverse effects of 0.5% timolol-2% dorzolamid (TD) and 0.5% timolol-0.2% brimonidine (TB) fixedcombination in patients with primary open-angle glaucoma (POAG) or ocular hypertension (OH). Mateials and Methods: Forty-four eyes of 22 patients followed with the diagnosis of PAAG or OH and treated at least 6 months with only TD were enrolled to this study. The mean of the last three IOP measurements recorded when patients were using TD was calculated. After a month of washout period without topical therapy, the baseline IOP was measured. Then TB treatment was started 2 times daily. Follow-up visits were scheduled at 2nd and 4th weeks. IOP was measured and adverse effects were observed in these visits. Ocular discomfort with topical use of TB and TD was evaluated using a scale. Results: Mean IOP measurement were 16.62±2.50 with TD, 15.46±2.52 with TB and 23.20±1.79 mmHg after washout period. TB fixed combination significantly reduced IOP (p<0.0001). A low statistically significant difference was observed between the mean IOP measurements obtained with TD and TB (p=0.04). Ocular discomfort scores were 2.00±0.55 with TD and 1.20±0.41 with TB (p<0.001). The side effects observed during the use of TB were conjunctival hyperemia in 3 patients, oral dryness in 5 patients and temporary blurred vision in1 patient. Conclusion: In this study, we observed that the fixed combination of TB has significantly reduced IOP as good as TD, in patients with PAOG or OH. Also, TB was topically well tolerated with less ocular discomfort than TD.

Özet

Amaç: Primer açık açılı glokomlu (PAAG) ve oküler hipertansiyonlu (OH) hastalarda topikal olarak kullanılan timolol (%0.5)-dorzolamid (%2) (TD) ile timolol (%0.5)-brimonidin (%0.2) (TB) sabit kombinasyonlarının göz içi basıncını (GİB) düşürücü etkinliklerini ve yan etkilerini karşılaştırmak. Gereç ve Yöntem: Glokom birimimizde PAAG ve OH tanısı ile takip edilen, en az altı aydan beri sadece TD kullanan 22 hastanın 44 gözü çalışmaya dahil edildi. TD kullanırken alınan son üç GİB ölçümlerinin ortalaması kaydedildi. İlaçsız bir aylık takipten sonra, bazal GİB ölçümleri alındı. Günde iki kez TB tedavisine geçilen hastalar iki hafta ve dört hafta sonunda yan etkiler ve GİB açısından değerlendirildiler. Bir eşel kullanılarak TD kullanılırken ve TB'nin damlatılma sırasında gözde yarattığı lokal rahatsızlık da değerlendirildi. Bulgular: Hastaların ortalama GİB 'ları TD kullanırken 16.62±2.50, ilaçsız dönem sonunda 23.20±1.79 ve TB kullanırken 15.46±2.52 mmHg olarak saptandı. İstatistiksel olarak TB' nin GİB' nı anlamlı olarak düşürdüğü (p< 0.0001), TB ve TD' nin GİB ‘nı düşürücü etkinlikleri arasında istatistiksel olarak düşük derecede anlamlı bir fark olduğu görüldü (p= 0.04). İlaçların gözde yarattığı lokal rahatsızlık hissi skorlaması; TD kullanırken 2.00±0.55, TB kullanırken ise 1.20±0.41 olarak ölçüldü (p<0.001). TB'e bağlı olarak üç hastada konjonktival hiperemi, beş hastada ağız kuruluğu ve bir hastada da geçici görme bulanıklığı ortaya çıktı. Sonuç: Çalışmamızda TB sabit kombinasyonunun, PAAG ve OH hastalarında TD kadar anlamlı düzeyde GİB düşüşü sağladığını tespit ettik. Ayrıca TB, damlatma esnasında TD' ye göre daha az rahatsızlık hissi vermektedir.
