    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.

    Keratoplasty indications and outcomes: The experience of a tertiary health center in Southeastern of Turkey
    (2019) Balsak, Selahattin; Yildiz Ekinci, Dilbade
    Aim: The study aims to report the indications of keratoplasty surgeries and our surgical outcomes performed in our hospital that provides tertiary health care.Materials and Methods: This retrospective study was conducted analyzing the files of the patients undergone keratoplasty for optical, therapeutic and tectonic purposes between 2014-2018. The patients' age, gender, indication for keratoplasty, preoperative and postoperative best-corrected visual acuity and surgical technique preferred, whether graft rejection developed or not during postoperative follow-ups, treatments administered to the patients developed rejection and follow-up periods were recorded.Results: The study included 200 eyes of 174 patients undergone keratoplasty. Of the eyes 180 (90%), 13 (6.5%) and 7 (3.5%) received corneal transplantation for optical purpose, for tectonic/therapeutic purpose and for cosmetic purpose respectively. The mean follow-up period was 21.7±6.2 months (range 6-48 months). Of the eyes 78 (39%), 40 (20%), 25 (12.5%), 19 (9.5%), 16 (8%), 11 (5.5%), and 9 (4.5%) were operated due to infectious/non-infectious corneal scar, pseudophakic/aphakic bullous keratopathy, graft failure/rejection, corneal dystrophy, keratoconus, keratitis/abscess and spontaneous corneal perforation respectively. Forty (20%) of the eyes developed allograft reaction. At the end of the study period, 50 (25%) eyes could not maintain graft transparency. The most common causes of inability to maintain graft transparency were endothelial failure and allograft reaction.Conclusion: Keratoplasty is an important and effective surgical method that increases visual acuity in blindness conditions caused by corneal diseases.Keywords: Cornea; graft survival; keratoplasty.
