Abstract

Aim: The assesment of changes in stereopsis with age Material and Methods: One hundred and sixty subjects aged between 20 and 79 years with no ocular disease were divided into 6 groups by age. Ages of the groups were between 20-29 in l[h group, 30-39 in 2nd group, 40-49 in 3th group, 50-59 in 4th group, 60-69 in 5th group, 70-79 in (5th group. All had corrected visual acuity of at least 0.8 monocularly. Stereoacuity was evaluated by Randot test in contour and randomdot patern. Results: Mean age was 46.17±5.52 years. The results of test showed reduction of stereopsis with increasing age (p<0.05). Mean stereoacuity obtouch contour stereogram was 56.6 arc of second in the first group; 67.5 arcsec in second group; 128.3 arcsec in third group; 140.4 arcsec in fourth group; 194.5 arc-sec in fifth group; 505.62 arcsec in sixth group. Mean randomdot patern stereoacuity was 281.25 arc of second in the first group, 362.5 arcsec in second group, 377.9 arcsec in third group, 377.9 arcsec in fourth group, 414.06 arcsec in fifth group, 468.75 arcsec in sixth group. When contour stereogram values were analysed statistically, stereoacuity in 6A group was increased significantly compared to others (p&#8212; 0.001). There was no statistically significant difference in randomdot stereoacuity among groups (p>0.05). Conclusion: Stereoacuity declined slowly until seventh decade, statistically significant drop was seen in seventh decade. We tought that it might be related to decrease of cerebral function with aging.

Özet

Amaç: Değişik yaş gruplarındaki bireylerde stereopsis keskinliklerinin değerlendirilmesi Gereç ve Yöntem: Ocak-Ağuslos 2005 arasında göz polikliniğine başvuran, yaşlan 20-79 arasında değişen 160 hasta çalışma kapsamına alındı. Tüm hastalara ayrıntılı göz muayenesi yapıldı. Düzeltilmiş görme keskinliği monoküler en az 0.8 olan olgular çalışma kapsamına alındı. Stereokeskinlik Randot stereotest ile randomdot ve kontür paternde değerlendirildi. Hastalar yaş gruplarına göre 6 gruba ayrıldı. 1. grup 20-29. 2. grup 30-39.3. grup 40-49. 4. grup 50-59.5. grup 60-69.6. grup 70-79 yaşlar arası olarak belirlendi. Bulgular: Hastaların yaş ortalaması 46.17±5.52 yıl idi. 1. grupta kontür stereogram değeri ortalama 56.66 ark/saniye, 2.grupta 67.5 ark/saniye, 3.grupta 128.37 ark/saniye, 4. grupta 140.4 ark/saniye, 5.grupta 194.5 ark/saniye, ö.grupta 505.62 ark/saniye idi. 1. grupta randomdot stereopsis değeri ortalama 281.25 ark/saniye, 2.grupta362.5 ark/saniye, 3.grupta 377.9 ark/saniye, 4.grupta 377.9 ark/saniye, 5.grupta 414.06 ark/saniye, 6. grupta 468.75 ark/saniye idi. Yaş gruplarındaki kontür stereogram değerleri istatistiksel olarak analiz edildiğinde 6. grupta diğer gruplara göre anlamlı olarak daha yüksek olduğu saptandı(p= 0.001). Grupların randomdot stereopsis değerleri arasında ise istatistiksel olarak anlamlı fark bulunamadı(p> 0:05). Sonuç: Çalışmamızda 7. dekada kadar stereopsis düzeyinde yavaş bir azalma gözlenirken, yedinci dekadda anlamlı düşüş saptanmıştır. Biz bu durumun yaşlanma ile birlikte serebral fonksiyonların azalmasına bağlı olduğunu düşünmekteyiz.
