Tujuan: menilai prevalensi katarak terinduksi radiasi, serta menghubungkannya
dengan dosis paparan radiasi dan penggunaan perlengkapan proteksi radiasi.
Metode: Studi potong lintang dan studi kasus-kontrol. Seratus delapan puluh subyek
berpartisipasi dalam penelitian. Prevalensi katarak terinduksi radiasi dinilai
menggunakan analisis Scheimpflug pada alat Pentacam®-Oculus. Dosis paparan
radiasi kumulatif dan penggunaan perlengkapan proteksi radiasi pada subyek
diidentifikasi melalui kuesioner dan personal dosimeter.
Hasil: Prevalensi katarak terinduksi radiasi sebanyak 16.7%. Median dosis radiasi
kumulatif berdasarkan kuesioner menunjukkan median 0,8 (0.1- 35.6) Gy. Hubungan
korelasi positif didapatkan antara dosis radiasi kumulatif dengan densitas lensa (R
Spearman= 0.64). Sebanyak 83.9% subyek menggunakan tabir pada 71-100% masa
kerjanya, tetapi mayoritas subyek penelitian (40.6%), tidak menggunakan kacamata
pelindung. Peningkatan risiko katarak terinduksi radiasi meningkat secara bermakna
seiring dengan kepatuhan penggunaan proteksi radiasi yang kurang. Subyek dengan
proteksi tabir radiasi 31-50% dari masa kerjanya meningkatkan risiko katarak 10.80
kali lipat (IK 95% 1.05-111.49, p=0.044). Sementara itu, kelompok proteksi tabir
radiasi 51-70% meningkatkan risiko katarak 8.64 kali lipat (p=0.001). Subyek yang
tidak memakai kacamata pelindung memiliki OR 164.3 (IK 95% 19.81-1363)
dibandingkan dengan kelompok pengguna kacamata pelindung.
Kesimpulan: Katarak terinduksi radiasi pada pekerja radiasi bidang kardiologi
intervensi tergantung pada dosis paparan radiasi dan penggunaan proteksi radiasi.
Oleh karena itu, kepatuhan pekerja radiasi perlu ditingkatkan sesuai ketentuan
proteksi radiasi.
Objectives: to determine the prevalence of radiation-induced cataract and correlate
with radiation exposure dose and radiation protection use among radiation workers of
interventional cardiology.
Methods: A cross-sectional and retrospective case-control study. One hundred and
eighty subjects were included. Prevalence of radiation-induced cataract was assessed
using Scheimpflug analysis on the Pentacam®-Oculus. Individual cumulative
radiation exposure dose and radiation protection use of subjects were identified from
questionnaire and personal dosimeter.
Results: The prevalence of radiation-induced cataract was 16.7%. Median cumulative
radiation dose was 0.8 (0.1-35.6) Gy. A positive correlation was found between
cumulative radiation dose and lens density (RSpearman=0.64). This study showed that
83.9% of subjects used ceiling-suspended shield in 71-100% of their working period,
however the majority of subjects (40.6%) did not wear protective eyewear.
Statistically significant increasing risk of cataract was found along with unresponsive
use of radiation protection. The subjects using ceiling-suspended shield in 31-50% of
their working period were increasing their cataract risk by 10.80 times (95% CI 1.05-
111.49, p=0.044). Meanwhile, the subjects using protective eyewear in 51-70% of
their working period were increasing their cataract risk by 8.64 times (p=0.001).
Subjects who did not wear protective eyewear had an OR 164.3 (95% CI 19.81-1363)
compared to those who wore protective eyewear.
Conclusion: Radiation-induced cataract among radiation workers of interventional
cardiology was depend on radiation exposure dose and radiation protection.
Therefore, the compliance of radiation safety recommendation should be improved.
