    An Analysis of Morphometric Qualities of Bulbus Oculi in Cataract Patients: A Comparative Biometric Study
    (Wiley, 2016) Atesoglu, Sibel; Senol, Deniz; Balsak, Selahattin; Alakus, Mehmet Fuat; Ozbag, Davut; Dag, Umut
    Cataract is considered to be the primary reason for curable blindness that is caused by progressive loss of lens transparency and affects millions of people around the world. This study aims to analyze the changes in morphometric qualities of bulbus oculi (BO) as well as its morphometric measurements such as anterior chamber depth (ACD), lens thickness (LT), vitreous length (VL), axial length (AL), etc. depending on age and gender in cataract patients through comparison with healthy eyes. 200 eyes with cataract were separately analyzed in five different categories of ages for males and females at the ages of 40-89. Biometric measurements of a total of 128 eyes (64 males and 64 females) were used as the control group. The study revealed a strong negative relation between age and ACD and a strong positive relation between age and LT in males and females for healthy eyes and eyes with cataract (P<0.05). No significant relation was found for VL and AL in either gender (P>0.05). A significant decrease was observed in ACD with aging while a positive correlation with age was detected in LT. We believe that the data obtained from this study will serve as a guide for BO interventions, diagnose and treatment stages and training of physician assistants. Anat Rec, 299:1308-1312, 2016.

    Impact of vitamin D supplementation on the ocular surface in patients with vitamin d deficiency
    (2020) Alakus, Mehmet Fuat; Oncul, Hasan; Yilmaz Oncul, Fatma; Dag, Umut; Arac, Esref
    Aim: The aim of this study was to determine the effect of vitamin D (vit D) supplementation on the ocular surface parameters in patients with vit D deficiency.Material and Methods: In total, 63 patients with serum vit D deficiency were included. Patients were treated with an oral dose of 300.000 IU cholecalciferol. The ocular surface disease index (OSDI) questionnaire, fluorescein tears breakup time (FBUT), Oxford score, and Schirmer’s 1 test were performed for all patients. The data was obtained initially and at 4, 8, and 12 weeks after vit D supplementation.Results: Forty-nine of the patients were female and 14 were male. The mean age was 30.8±9.7 (18–58) years. All 63 patients came to the first follow-up, 57 patients came to the second follow-up, and 48 patients came to the third follow-up. The OSDI and Oxford scores yielded statistically significant decreases, while Schirmer’s 1 test and FBUT values showed a statistically significant increase after treatment with vit D. A positive correlation was observed between vit D values and FBUT and Schirmer’s 1 values; there was a negative correlation between OSDI values (r=0.286 and p0.001, r=0.219 and p=0.032, r = -0.357 and p0.001, respectively). The dry eye findings improved significantly after vit D supplementation in all cases. Conclusion: During clinical follow-up, it is important to evaluate serum vit D levels in patients with dry eye syndrome (DES). Increasing their vit D levels will help clinicians to treat DES quickly and effectively.
