Abstract
<p><em>Chronic inhalation of organic solvents causes retinal toxicity such as decreased color vision and contrast sensitivity because organic solvents cause damage to photoreceptor function, changes in cortical or retinal neurotransmitter systems such as glutamate, dopamine and acetylcholine and changes in function in parvo, magno and coniocellular cells.</em><em> </em><strong><em>Method</em></strong><em>: The sample of this study consisted of 45 gas station operators who were divided into 3 groups, namely those who worked 1 year</em><em>-</em><em>5 years, 5 years</em><em>-</em><em>10 years and </em><em>&gt;</em><em>10 years. All subjects underwent </em><em>q</em><em>uantitative color vision examination by calculating the value of the color confusion index (CCI) using Fansworth D15. Contrast sensitivity examination is by determining the log contrast sensitivity value using the Pelli-Robson test.</em><em> </em><strong><em>Results</em></strong><em>: CCI values&gt; 1.00 and log contrast sensitivity values &lt;1.65 were found in officers who worked for </em><em>&gt;</em><em>10 years by 12 subjects (80%). Statistically there is a significant relationship between the duration of work with the decrease in color vision and contrast sensitivity (P Value 0,000).</em><em> </em><strong><em>Conclusion</em></strong><em>: There is a significant relationship between the duration of exposure to organic solvents with a decrease in color vision and contrast sensitivity in operator officers who work </em><em>&gt;</em><em>10 years.</em></p>
Highlights
Chronic inhalation of organic solvents causes retinal toxicity such as decreased color vision and contrast sensitivity because organic solvents cause damage to photoreceptor function, changes in cortical or retinal neurotransmitter systems such as glutamate, dopamine and acetylcholine and changes in function in parvo, magno and coniocellular cells
Pada tabel 5.2 dapat dilihat bahwa 15 subyek (100%) petugas operator SPBU yang bekerja selama [1,2,3,4,5] tahun memiliki penglihatan warna normal dengan nilai color confusion index (CCI) 1,00
Lima belas subyek (100%) petugas operator SPBU yang bekerja selama [5,6,7,8,9,10] tahun memiliki penglihatan warna normal dengan nilai CCI 1,00
Summary
Cara ukur : Mengukur lamanya paparan dengan menghitung lama bekerja petugas operator di SPBU. Hasil ukur: Pengelompokan berdasarkan lamanya bekerja sebagai petugas operator di SPBU. Cara ukur : Subjek diminta menyusun kembali 15 cap tersebut sesuai dengan spektrum warnanya, hasil ini di presentasikan sebagai color confusion index, Nilai CCI dihitung dengan membagi total color vision score dari tiap individu yang merupakan jumlah perbedaan warna menggunakan total color difference score (TCDS), kemudian dibandingkan dengan nilai reference. Bila subjek bisa menyusun Fansworth D15 sesuai dengan spektrum warna yang sudah disesuaikan maka nilai CCI adalah 1.0. Bila subjek melakukan kesalahan penempatan cap atau susunan cap membentuk pola seperti protan, deutan atau tritan, maka nilai CCI akan lebih besar dari 1.0. Semakin lama bekerja sebagai petugas operator SPBU maka semakin lama terpapar dengan organic solvent sehingga akan terjadi penurunan penglihatan warna dan sensitivitas kontras
