ABSTRACT
Objective: This study aims to investigate the aging-related
change of the oculomotor tests (saccad, smooth pursuit and optokinetic),
which have an important place in the evaluation of the
central vestibular system, and to compare these tests by age groups.
Material and Methods: Saccade test, smooth pursuit test and optokinetic
test results of 90 (30 young individuals aged 18-45 as individuals
group 1, 30 adult individuals aged 46-65 as group 2 and 30 elderly individuals
aged 66 and older as group 3) who applied to the otorhinolaryngology
outpatient clinic between September 2017-December 2018
were evaluated retrospectively. The results of the saccade test, smooth
pursuit test and optokinetic test applied to these individuals were compared
according to the groups. Results: Elderly individuals had worse
saccade and smooth pursuit functions than young and adult individuals
(p<0.05). Saccade test accuracy value, smooth pursuit test gain and
asymmetry values were observed to decrease after 65 years (p<0.05).
Optokinetic test gain value was observed to decrease after age 45
(p<0.05). The 1. group had the best latency value and latency value was
significantly longer with aging (p<0.05). Conclusion: Ages of individuals
are an important factor for oculomotor tests. While young individuals
have the best oculomotor test scores, the scores of the tests
worsen with aging.

ÖZET
Amaç: Santral vestibüler sistemin değerlendirilmesinde önemli
bir yeri olan okülomotor testlerin (sakkad, smooth pursuit ve optokinetik)
yaşlanmayla olan değişimini araştırmak ve bu testleri yaş gruplarına
göre karşılaştırmaktır. Gereçler ve Yöntemler: Eylül
2017-Aralık 2018 tarihleri arasında kulak burun boğaz polikliniğine
başvuran 90 bireyin (yaş aralığı 18-45 yıl olan 30 genç birey 1. grup
olarak, yaş aralığı 46-65 yıl olan 30 yetişkin birey 2. grup olarak ve
yaşları 66 yaş ve üzeri olan 30 yaşlı birey 3. grup olarak) sakkad testi,
smooth pursuit testi ve optokinetik testi sonuçları retrospektif olarak
değerlendirildi. Bu bireylere uygulanan sakkad testi, smooth pursuit
testi ve optokinetik testi sonuçları gruplara göre karşılaştırıldı. Bulgular:
Yaşlı bireyler, genç ve yetişkin bireylere göre daha kötü sakkad ve
smooth pursuit işlevlerine sahiptir (p<0,05). Sakkad testi doğruluk değerinin,
smooth pursuit testi kazanç ve asimetri değerinin 65 yaşından
sonra azaldığı izlendi (p<0,05). Optokinetik test kazanç değerinin ise 45
yaşından sonra azaldığı izlendi (p<0,05). Sakkad testi latans değerine
ise en iyi 1. grup sahipti ve latansın yaşlanmayla birlikte anlamlı şekilde
uzadığı izlendi (p<0,05). Sonuç: Bireylerin yaşları okülomotor
testler için önemli bir faktördür. En iyi okülomotor test skorlarına genç
bireyler sahipken, yaşlanmayla birlikte testlerin skorları da kötüleşmektedir.
