    The Role of Heredity and the Prevalence of Strabismus in Families with Accommodative, Partial Accommodative, and Infantile Esotropia
    (2020) Eroglu, Fatma Corak; Oto, Sibel; Sahin, Feride Iffet; Terzi, Yunus; Kaya, Ozge Ozer; Tekindal, Mustafa Agah; 0000-0003-0171-4200; 0000-0001-7308-9673; 0000-0001-5612-9696; 32631000; AAJ-4668-2021; AAC-7232-2020; B-4372-2018
    Objectives: To investigate the prevalence of strabismus in families of a proband with accommodative, partial accommodative, or infantile esotropia, and to evaluate the mode of inheritance and the role of consanguineous marriages in this prevalence. Materials and Methods: Families of probands with comitant strabismus were invited to participate in the study. The family members of 139 subjects with accommodative, 55 with partial accommodative, and 21 with infantile esotropia agreed to participate. Detailed family trees were constructed. The first- and second-degree relatives were invited for a complete ophthalmological examination, and 518 individuals from 168 families were evaluated. The role of consanguinity, the presence of tropia, phoria (>= 8 PD), microtropia, and hypermetropia (>= 3.00 D) among first- and second-degree relatives were analyzed. Results: A non-Mendelian pattern was found in 49 families (23%), an autosomal dominant pattern in 39 families (18%), and an autosomal recessive pattern in 6 families (3%). The prevalence of consanguineous marriages among parents of probands was 18.1%, 22.6%, and 14.3% in the accommodative, partial accommodative, and infantile esotropia groups, respectively (p=0.652). The prevalence of strabismus in first-degree relatives was 58.9%, 45.5%, and 38.1%, respectively (p=0.07). The prevalence of microtropia in probands' siblings was significantly higher in the accommodative esotropia group (p=0.034). Conclusion: Sporadic cases and non-Mendelian inheritance were more frequent than autosomal recessive inheritance. Autosomal recessive inheritance was found not to be frequent in consanguineous marriages. The prevalence of strabismus and microtropia was significantly higher in families of esotropia cases than in the general population.

    Evaluation of choroidal and retinal thickness measurements in adult hemodialysis patients using spectral-domain optical coherence tomography
    (2016) Kal, Ali; Kal, Oznur; Eroglu, Fatma Corak; Omer, Ozlem; Kucukdonmez, Cem; Yilmaz, Gursel; 0000-0002-2589-7294; 0000-0003-3003-0756; 27626146; AAK-6987-2021; D-5308-2015
    Purpose: To assess the effect of hemodialysis on retinal and choroidal thicknesses using spectral-domain optical coherence tomography (SD-OCT). Methods: In this prospective interventional study, 25 hemodialysis patients (17 male, 8 female) were enrolled. All participants underwent high-speed, high-resolution SD-OCT (lambda=840 mm; 26.000 A-scans/s; 5 mu m resolution) before and after hemodialysis. Choroidal thickness was measured perpendicularly from the outer edge of the retinal pigment epithelium to the choroid-sclera boundary at the fovea and at five additional points: 500 mu m and 1000 mu m nasal to the fovea and 500 mu m, 1000 mu m, and 1500 mu m temporal to the fovea. Two masked physicians performed the measurements. Choroidal and retinal thicknesses before and after hemodialysis were compared. Results: The median choroidal thicknesses before and after hemodialysis were 182 mu m (range, 103-374 mu m) and 161 mu m (range, 90-353 mu m), respectively (P<0.001). The median retinal thicknesses were 246 mu m (range, 179-296 mu m) before and 248 mu m (range, 141-299 mu m) after hemodialysis (P>0.05). Systolic arterial pressure, diastolic arterial pressure, mean arterial pressure, heart rate, and ocular perfusion pressure significantly decreased after hemodialysis (P<0.001). Intraocular pressure did not vary significantly (P=0.540). Conclusion: Hemodialysis seems to cause a significant decrease in choroidal thickness, whereas it has no effect on retinal thickness. This significant decrease in choroidal thickness might be due to the extensive fluid absorption in hemodialysis, which could result in decreased ocular blood flow.
