Objective: To investigate the various ocular findings associated with spina bifida. Material and Methods: This study is a retrospective study which included 122 patients (56 female patients and 66 male patients) with spina bifida who were referred to Ophthalmology Department for ophthalmologic evaluation between 2015 and 2017. All patients had shunt replacement surgery by Neurosurgery Department before the ophthalmic examinations. Results: Results of the Hirschberg and cover tests showed that 49 (40.5%) patients had strabismus and 72 (59.5%) patients did not have strabismus. The mean spherical equivalent refraction was +1±2.01 D in the right eyes and+1.12±1.97 D in the left eyes. The mean astigmatism was-1.04±0.92 D in the right eyes and-1.08±0.95 D in the left eyes. Hypermetropia was common (80%) among the patients with esotropia in the left eye, myopia was common (75%) among the patients with exotropia in the left eye. There was a statistically significant relationship between the spherical equivalent refraction of the left eye and strabismus type (X2=5.695; p=0.045). Funduscopic examination detected unilateral optic atrophy in three (2.5%) patients, bilateral optic atrophy in six (4.9%) patients, and bilateral papilledema in three (2.5%) patients. Strabismus was more common in patients with fundus abnormalities (n=8, 66.7%). Conclusions: Ocular findings such as strabismus and refractory error are very common in patients with spina bifida. Therefore, these patients should be followed up closely after birth for abnormal ocular findings by a team of ophthalmologists and neurosurgeons.

Amaç: Spina bifidalı hastalarda görülen çeşitli oftalmik bulguların sıklığını değerlendirmek Gereç ve Yöntemler: Bu çalışma 2015-2017 yılları arasında oftalmolojik muayene amaçlı Oftalmoloji Departmanı'na refere edilmiş 122 hastayı (56 kadın, 66 erkek) içeren retrospektif bir çalışmadır. Tüm hastalar oftalmolojik muayene öncesi Beyin ve Sinir Cerrahisi Departmanı tarafından şant replasmanı uygulanmış hastalardır. Bulgular: Hirschberg ve kapama testinde 49 (40.5%) hastada kayma saptanmış, 72 (%59,5) hastada kayma saptanmamıştır. Ortalama sferik ekivalan sağ gözlerde +1±2,01 D, sol gözlerde+1,12±1,97 D olarak saptanmıştır. Ortalama astigmatizma sağ gözlerde - 1,04±0,92 D, sol gözlerde -1,08±0,95 D olarak bulunmuştur. Sol gözlerde ezotropyası olan hastalarda hipermetropi (%80) oranı yüksekti, ekzotropyası olan hastalarda ise miyopi (%75) oranı yüksekti. Sol gözlerde sferik ekivalan refraksiyonu ve kayma tipi arasındaki ilişki istatistiksel olarak anlamlıydı (X2=5,695; p=0,045). Fundus incelemesinde 3 hastada (%2,5) tek taraflı optik atrofi, 6 (%4,9) hastada çift taraflı optik atrofi, 3 (%2,5) hastada çift taraflı papilödem saptanmıştır. Anormal fundus bulgusu olan hastalarda olmayanlara göre kayma daha sıktı (n=8, %66,7). Sonuç: Kayma, refraktif bozukluklar gibi göz bulguları spina bifidalı hastalarda oldukça sık görülmektedir. Bu hastalar anormal göz bulguları açısından doğumdan itibaren oftalmologlar ile beyin ve sinir cerrahlarından oluşan bir ekip tarafından yakından takip edilmelidir.
