Abstract

Objective: To investigate the decrease of contrast sensitivity in non proliferative diabetic retinopathy (NPDR) of type 2 DM. Method : This study was an observational study with cross sectional approach. The samples were 37 diabetes mellitus patients, which is 20 males and 17 female. The other group was normal people, which is contained by 15 males and 22 females. Their ages ranging from 40 to 50 years old. Both groups performed by four times contrast sensitivity test using Cambridge Low Contrast Sensitivity Chart, the result then summarized and the score matched with the conversion table. Those scores then tested using Mann-Whitney U statistical test. Result : From non-parametric statistical test we found p=0,001 or p< 0,05, which means there is significant contrast sensitivity differences between diabetes mellitus patients group and normal people group. The mean of contrast sensitivity on diabetes mellitus group was 217,00±65,703 and on normal people was 431,35±50,34.Conclusion : There were some decreased of contrast sensitivity on diabetes mellitus patients (NPDR of type 2 DM) than on normal people. Key words : Non Proliferative Diabetic Retinopathy (NPDR) of type 2 DM, contrast sensitivity. Tuj uan : - Mengetahui penurunan contrast sensitivity pada retinopati diabetik non proliferative (NPDR) DM tipe 2 Metode : Merupakan penelitian observasional dengan pengambilan data cross sectional. Jumlah sampel penderita diabetes mellitus 37, jumlah sampel yang diperoleh terdiri dari 20 orang laki-laki dan 17 orang perempuan. Pada sampel orang normal, berhasil didapat 15 sampel laki-laki dan 22 sampel perempuan. Umur kelompok diabetes mellitus maupun orang normal antara 40 sampai 50 tahun. Kedua kelompok tersebut kemudian diperiksa contrast sensitivity dengan menggunakan Cambridge Low Contrast Sensitivity Chart sebanyak 4x kemudian hasilnya dijumlahkan dan dicocokan nilainya berdasarkan tabel konversi yang sudah ada. Nilai tersebut kernudian diuji statistikidengan uji Mann-Whitney U. Hasil : ' Uji statistik non parametrik dcngan menggunakan uji Mann-Whitncy U, didapatkan p=0,001 atau p<0,05, yang berarti terdapat perbedaan yang signifikan contra•t •ensitivity antara kelornpok penderita diabetes mellitus dan kelompok non diabetes mellitus (orang normal). Rerata contrastsensitivity pada kelompok diabetes mellitus 217.00±65.703, sedangkan pada kelompok non diabetes mellitus (orang normal). 431.35±50.34. Kesimpulan : Pada penderita diabetes mellitus (NPDR DM tipe 2) terjadi penurunan contrast sensitivity dibanding orang normal
