“…5 Windham ve arkadaşları 11 ise, görme keskinliği, kontrast duyarlılık ve stereopsis düzeyi yüksek olan yaşlıların olmayanlara göre günlük işleri yapmadaki beceri ve yaşam kalitelerinin yüksek olduğunu saptamışlardır. Ülkemizden yapılan 160 hastayı kapsayan bir çalışmada ise 12 grupları arasında anlamlı olabilecek stereopsis değişikliği saptamadık (Tablo1 18 şizofreni hastalarında stereopsis düzeyinde anlamlı bir azalma olduğunu rapor etmiştik. Alzheimer hastalarında da yaşla bağlantısı olmaksızın stereopsisin etkilendiği bildirilmiştir.…”

“…19 Bu hastalarda görme keskinliği tam olsa bile stereopsisin azaldığı gözlemlenmiş, özellikle büyük retina ganglion hücrelerinin hasar gördüğü ve stereopsisteki azalmanın buna bağlı olabileceği bildirilmiştir. 12,20 Refraksiyonun stereopsis üzerine etkisi konusunda çok çalışma olmamakla birlikte anizometropinin stereopsiste az miktarda da olsa azalmaya sebep olduğu bildirilmiştir. 6 Bundan hareketle biz olguları refraksiyon kusurlarına göre kategorilere ayırdık ve stereopsis düzeylerini birbiriyle kıyasladık.…”

Amaç: Refraksiyon kusurları ve yaşın stereopsis üzerine olan etkilerini araştırmak. Ge reç ve Yön tem: Çalışmaya, gözlerinde refraksiyon kusuru dışında herhangi bir patoloji olmayan, görme keskinlikleri tam; randomize olarak şeçilmiş 1488 olgu dahil edildi. Olgular 10 -19 (Grup 2, n=258), 20 -29 (Grup 2, n=264), 30 -39 (Grup 3, n=246), 40-49 (Grup 4, n=246), 50 -59 (Grup 5, n=246) ve 60 ila üzeri (Grup 6, n=228) olmak üzere yaşlarına göre 6 gruba ayrıldı. Ayrıca her grup kendi içerisinde miyop (a), miyopik astigmatizma (b), hipermetropi (c), hipermetropik astigmatizma (d), emetrop (e) olmak üzere beşe ayrıldı. Olguların refraksiyon kusurları düzeltildikten sonra polarize gözlükle 16 inç (405 mm) mesafeden Titmus testi uygulandı. Olguların stereopsis düzeyleri titmus test üzerindeki "Halka testi" kullanılarak değerlendirildi. Sum maryPur po se: To investigate the effects of age and refractive errors on stereopsis. Ma te ri al and Met hod: The present study included 1488 cases which were randomly selected, had full vision and no eye pathology except refractive errors. The patients were divided into six groups according to their age: 10-19 (Group 1, n=258), 20-29 (Group 2, n=264), 30-39 (Group 3, n=246), 40-49 (Group 4, n=246), 50-59 (Group 5, n=246), and 60 years and over (Group 6, n=228). Additionally, each group was divided according to refractive errors: myopia (a), myopic astigmatism (b), hyperopia (c), hyperopic astigmatism (d), emetropia (e). Titmus test was applied to all cases from 16 inches (405 mm) distance with polarized glasses after correcting the refractive errors. Stereoacuity was evaluated using the Titmus circle test. Re sults: Mean stereoacuity was 41.1±3.2 arc\s in group 1, 45.3±24.6 arc\s in group 2, 42.6±5.0 arc\s in group 3, 44.1±10.7 arc\s in group 4, 45.8±24.8 arc\s in group 5, and 41.3±3.4 arc\s in group 6. Mean stereoacuity was found to be 45.4±24.2 arc\s in myopia, 41.3±4.2 arc\s in myopic astigmatism, 45.3±21.4 arc\s in hyperopia, 41.4±3.6 arc\s in hyperopic astigmatism, and 41.9±4.4 arc\s in emetropia in the refractive error groups. No statistically significant differences were detected in evaluation between age groups, refraction groups according to age and refraction groups. Dis cus si on: No significant effects of age and refractive errors on stereoacuity were found in our study. (Turk J Ophthalmol 2011; 41: 372-5)

Strabismus surgery may be responsible for some restrictions in ocular motility that may cause new problems after surgery. Most of the time these restrictions present as a complex motility problem after surgery that requires further treatment. There may be various reasons that cause motility restriction following strabismus surgery. Those are excessive shortening or inadvertent capture of extraocular muscles, transposition procedures and, the most challenging problem, postoperative scar tissue-adhesion formation. In this review the potential reasons for postoperative restrictive problems, preventive measures and finally the treatment options for such problems are overviewed.

Purpose: To examine the outcome of the use of donor sclera as spacer material in complicated cases of strabismus surgery. Methods: A retrospective cohort study on patients with complicated thyroidassociated ophthalmopathy (TAO) (n = 42) or congenital strabismus (n = 75). Patients underwent strabismus surgery during 1994-2014. The surgical results were evaluated in terms of the reduction in the angle of deviation, the need for reoperation, complications and patient satisfaction. Results: The majority of the TAO patients underwent surgery for vertical strabismus (n = 25). The vertical angle of deviation in the primary position was significantly reduced from a median of 23 prism dioptres (PD) to 2 PD (n = 35, p < 0.001). The horizontal angle of deviation in primary position for TAO patients with esotropia was significantly reduced, from a median of 35 PD to 2 PD (n = 17, p < 0.001). The majority of the congenital cases had horizontal strabismus (esotropia = 29, exotropia = 27). The angle of deviation in esotropia was reduced from a median of 29 PD to 8 PD (n = 36, p < 0.001) and in exotropia from 30 PD to 10 PD (n = 34, p < 0.001). Most of the patients were satisfied with the outcome of surgery, and only 12% required re-operation within 2 years. Conclusion: This is the first clinical study on the use of donor sclera as spacer material in complicated cases of strabismus surgery. The surgical results were good in terms of the reduction in the angle of deviation, the need for re-operation, complications and patient satisfaction, supporting the use of donor sclera for strabismus surgery.
