Abstract

Objectives: This study aimed to investigate the incidence of pterygium in a particular district of Istanbul, its association with age, and gender, and the severity of the disease. Methods: All patients aged ≥ 30 years referred to our outpatient clinics between January 2009 and December 2009 were included in this retrospective study. Age, gender, anterior segment photos, and findings of biomicroscopic eye examination were evaluated. Results: The incidence of pterygium for all age groups was 2.91% (male 1.75%, female 3.67%) with an increasing incidence with age. A significant difference was detected in its incidence favoring female patients in 40-49, and 70-79, and male patients in ≥ 80 age groups, respectively. In addition, pterygium was seen in one (75.4%) or both eyes (24.6%) preferring right or left eye in 50.7%, and 49.3% of the patients, respectively. Pterygium was in nasal or temporal region in 98%, and 2% of the patients, respectively. The disease state in 59.9% of the patients was consistent with Stage 2 pterygium. The distance of pterygium from limbus was observed greatest in 60-69, and at a minimum in 40-49 age groups. No relationship was found between eye colour and development of pterygium. Conclusion: The incidence of pterygium increases with age. Incidence of pterygium differs between genders but without any significant difference. Its occurrence in one or both eyes and in right and left eyes was not influenced by gender of the patients. A statistically significant impact of eye colour of the patient on the development of pterygium was not disclosed. J Clin Exp Invest 2013; 4 (4): 436-442

Abstract

Amaç: Bu çalışma, İstanbul ilinde belirli bir bölgedeki pterjiyum insidansını, yaş, cinsiyet ve hastalık şiddetini araştırmayı amaçladı. Yöntemler: Bu retrospektif çalışmada, polikliniğimize Ocak 2009 ve Aralık 2009 tarihleri arasında başvuran 30 yaş ve üzerindeki tüm hastalar dâhil edildi. Hastaların yaş, cinsiyet, ön segment fotoğrafları, biomikroskopik göz muayenesi bulguları değerlendirildi. Bulgular: Pterjiyumun tüm yaş grupları için prevelansının %2,91 (erkeklerde %1,75, kadınlarda %3,67) olduğu; yaş arttıkça pterjiyum görülme sıklığının arttığı, 40-49 yaş grubunda ve 70-79 yaş grubunda bayanlar lehine, 80 ve üstü yaş grubunda ise erkekler lehine anlamlı bir prevelans farkı mevcut olduğu ortaya konuldu. Ayrıca, pterjiyum %75,4 hastada tek tarafta, %24,6 hastada ise çift tarafta; %50,7 hastada sağ gözde, %49,3 hastada sol gözde görüldü. Pterjiyum, hastaların %98\'inde nazal bölgede iken %2\'sinde temporal bölgede idi. Hastaların %59,9\' u Evre 2 pterjiyum ile uyumlu idi. Hastanın göz rengi ile pterjiyum gelişmesi arasında bir ilişki yoktu. Sonuç: Pterjiyum gelişme riski yaş ilerledikçe yükselmektedir. Pterjiyum prevelansı cinsiyet açısından farklılık gösterse de, bu fark anlamlı düzeyde değildir. Pterjiyumun tek ya da çift gözde görülme ile sağ ya da sol gözde görülmenin cinsiyetten etkilenmediği ortaya konulmuştur. Hastanın göz renginin pterjiyum gelişimi üzerine anlamlı bir etkisinin olmadığı izlendi.
