Latar belakang: Pterygium adalah penyakit pada mata yang sering dijumpai di daerah khatulistiwa terutama oleh pajanan ultraviolet, penyebab pterygium antara lain macam-macam zat iritan, faktor genetik, alergi, kekeringan pada mata, faktor angiogenik, dan infeksi papilomavirus. Pada perusahaan X banyak ditemukan kasus pterygium 5.3% pada observasi awal oleh Dinas Kesehatan.Metode: Penelitian ini menggunakan metode potong lintang. Sampel diambil secara purposive berdasarkan ruangan dengan pajanan debu tertinggi. Pengumpulan data dilakukan dengan wawancara langsung pada pekerja dan pemeriksaan pada mata.Hasil: Prevalensi pterygium akibat pajanan zat iritan debu kertas 68.2% dari 85 pekerja di rewinder enam dan sekitarnya. Riwayat merokok merupakan faktor yang bermakna (p-0.01).Kesimpulan: Debu kertas belum dapat dibuktikan signifikansinya secara statistik dengan kejadian pterygium, sementara perbandingan dengan studi-studi yang relevan menunjukkan bahwa prevalensi pterygium dengan pajanan debu kertas lebih tinggi dibandingkan dengan pajanan UV.

Background: Pterygium is an abnormal process in which the conjunctiva (a membrane that covers the white of the eye) grows into the cornea and most commonly found at the equator, due to prolong exposure to ultraviolet and infrared radiation from sunlight. Other environmental irritants identified were genetic factor, allergy, dry eyes, angiogenic factor, and papilloma virus infection. In the factory "X" Karawang, 5.3% pterygium cases were found as reported by the government reevaluation visit.

Method: The study was a cross-sectional. Sample collected using purposive method and had been exposed to high paper dust. Conducting interview, filling out questionnaires and eye examination, collected data.

Results: The Prevalence of identified pterygium was 68.2% from 85 workers at rewinder 6. Meanwhile smoking habit was the significant factor (r 0.O1).

Conclusion: Paper dust has not yet proven to be significant related to pterygium while descriptive comparison among several studies reported that the prevalence of pterygium was much higher related to paper dust (68.2%) compared to UV.
