Öğe Outcomes of Unilateral Inferior Oblique Myectomy Surgery in Inferior Oblique Overaction Due to Superior Oblique Palsy(Turkish Ophthalmological Soc, 2016) Yumusak, Erhan; Yolcu, Umit; Kucukevcilioglu, Murat; Diner, Oktay; Mutlu, Fatih MehmetObjectives: To present the outcomes of unilateral inferior oblique myectomy performed in patients with inferior oblique overaction due to superior oblique palsy. Materials and Methods: Twenty-seven eyes of 27 patients that underwent inferior oblique myectomy surgery for superior oblique palsy between 2002 and 2008 were included. Inferior oblique overaction scores (between 0-4) at preoperative, early postoperative (within 1 week after surgery) and late postoperative (earliest 6 months) visits were reviewed. Results: There were 12 male and 15 female patients. Eighteen were operated on the right eye, and 9 were operated on the left eye. The mean age was 15.62 +/- 13.31 years, and the mean follow-up was 17 +/- 11.28 months (range, 6-60 months). Patients who had horizontal component and V-pattern deviation were excluded. Preoperative and early postoperative inferior oblique overaction scores were 2.55 +/- 0.75 and 0.14 +/- 0.36, respectively, and the difference was statistically significant (p<0.01). This improvement was maintained up to the late postoperative period. Conclusion: Due to its promising short-term and long-term results, inferior oblique myectomy can be the first choice of surgery for inferior oblique overaction due to superior oblique palsy.Öğe Retinopathy of prematurity, diagnosis and standardization of the evaluation(Gazi Eye Foundation, 2015) Yumusak, Erhan; Mutlu, Fatih Mehmet; Sarica, Umit; Ogurel, ReyhanRetinopathy of prematurity (ROP) has been one of the issues about which the specialists have most argued but not compromised to that extent since its first definition. Restricted examination area of the eyes of the premature babies and difficulty of performing examination, and difficulty in achieving sufficient pupil dilatation have precluded the standardization of diagnosis and treatment. Plus disease, defined in 1980 has been used as an important indicator in the diagnosis and treatment of ROP. With a later revision, concepts such as preplus or threshold have been defined, and changes in posterior pole have gained much more importance. Desire of the ROP specialists in using technology towards the diagnosis of plus disease and consensus about the diagnosis has significantly increased in the last 10 years. In this article it was aimed to review the up-to-date studies about the diagnosis and treatment of ROP and plus disease.Öğe An Unusual Cause of Pseudopapillary Oedema: Hyperphosphatemic Hyperostosis Syndrome(Taylor & Francis Inc, 2016) Yumusak, Erhan; Mutlu, Fatih Mehmet; Gok, FaysalFor the first time, we report hyperphosphatemic hyperostosis syndrome as a cause for pseudopapillary oedema in a pediatric case. Clinical findings are presented and discussed with tomographic evaluation (optical coherence tomography and Heidelberg retinal tomography) of optic discs, visual-evoked potentials, and visual fields.Öğe Üst Oblik Paralizisine Bağlı Alt Oblik Aşırı Fonksiyonunda Tek Taraflı Alt Oblik Miyektomi Sonuçları(2016) Yumuşak, Mehmet Erhan; Yolcu, Ümit; Küçükevcilioğlu, Murat; Diner, Oktay; Mutlu, Fatih MehmetAmaç: Üst oblik paralizisine bağlı alt oblik aşırı fonksiyonu olgularında uyguladığımız tek taraflı alt oblik miyektomi sonuçlarını sunmaktır.Gereç ve Yöntem: 2002-2008 yılları arasında üst oblik paralizisine bağlı tek taraflı alt oblik miyektomi yapılan 27 hastanın 27 gözü çalışmaya dahil edildi. Hastaların ameliyat öncesi, ameliyat sonrası erken dönem (bir hafta içinde) ve ameliyat sonrası geç dönem (en erken 6. ayda) alt oblik aşırı fonksiyonu değerleri (0-4 arası) incelendi.Bulgular: On iki erkek, 15 kadın hasta mevcuttu. Çalışmada hastaların 18'i sağ 9'u ise sol gözünden ameliyat edildi. Yaş ortalaması 15,62±13,31 yıl ve ortalama takip süresi 17±11,28 ay (aralık: 6-60 ay) olarak bulundu. Horizontal komponent ve V patern deviyasyon olan olgular çalışma dışında bırakıldı. Ameliyat öncesi ve ameliyat sonrası erken dönem ortalama alt oblik aşırı fonksiyonu değerleri sırasıyla 2,55±0,75 ve 0,14±0,36 idi ve fark istatistiksel olarak anlamlıydı (p<0,01). Bu düzelmenin geç dönemde de korunduğu gözlendi.Sonuç: Gerek erken, gerekse geç dönem sonuçları açısından yüz güldürücü olması sebebiyle özellikle üst oblik paralizisine bağlı alt oblik aşırı fonksiyonlu olgularda alt oblik miyektomi ilk seçenek cerrahi yöntem olarak tercih edilebilir
