    The evaluation of the relationship between scleral and conjunctival thickness with age in a healthy Turkish population
    (2020) Kaya, Huseyin; Akkaya, Hasan Samed; Yilmaz, Ugur
    Aim: To evaluate the relationship between scleral and conjunctival thickness with age in normal subjectsMaterial and Methods: One hundred five normal subjects were evaluated in this study. Scleral thickness (ST) and conjunctival thickness( CT) were measured by Spectralis Anterior Segment Module Optical Coherence Tomography (AS-OCT). ST and CT were measured at a distance of 1,000, 2,000, 3,000, 4,000 and 5,000 microns from temporal scleral spur. The mean sclera (STmean) and conjunctival (CTmean) thickness were obtained by the mean of the sclera and conjunctival thickness at 5 points. The axial length (AL) was evaluated by using AL-Scan Optical Biometer(Nidek co.,ltd.). SPSS 21 was used for statistical analysis. Results: There was no significant difference between males and females according to ST, CT and AL values (p>0.05). There was a significant positive correlation between age and ST values at 2000, 3000, 4000, and 5000 micron apart from temporal scleral spur (r=0.237 p=0.015, r=0.241 p=0.013, r=0.276 p=0.004, r=0.202 p=0.039 respectively). There was a significant negative correlation between age and CT values at 3000, 4000 and, 5000 micron apart from temporal scleral spur(r= -0.222 p=0.023, r= -0.288 p=0.003,r= -0.350 p0.001). There was a significant positive correlation between age and STmean and, a negative between age and CTmean (r=0.289 p=0.003, r= -0.251 p=0.010) .Conclusion: According to this study ST positively and CT negatively correlated with age significantly.

    Inverstigation of corneal and lens densitometry in eyes of patients with primary myelofibrosis
    (2021) Yilmaz, Ugur; Akgun, Gulsum; Akbay, Burak
    Aim: To investigate the corneal-lens densitometry and endothelial cells of Primary myelofibrosis patients.Materials and Methods: We evaluated 49 eyes of 49 primary myelofibrosis patients on follow up in hematology clinic and compared to 46 eyes of 46 age and sex-matched control group . The Scheimpflug images of 90–270 degrees by Pentacam HR (Oculus Optikgeräte GmbH, Wetzlar, Germany) were used for measurement. After pupil dilatation, the corneal apex was marked by pentacam automatically and the diameter of central 6 mm around marked point was analyzed. PNS (Pentacam Nuclear Staging) software was used for densitometric analysis of the lens from a cylindrical region in the nucleus center. Specular Microscope CEM-530 (Nidek, Japan) was used for endothelial cell analysis. Results: There was no statistically significant difference between groups for age and gender(Table1). Corneal density and corneal volume were higher in the patient group but it was not statistically significant (respectively p=0.390, p=0.078). Lens density was found as statistically significantly higher in the patient group compared to the control group(p0.001). For the corneal endothelial analysis by specular microscopy, there was no statistically significant difference for cell density, the coefficient of variant and endothelial hexagonality (respectively, p=0.546, 0.671, 0.103).Conclusion: Primary myelofibrosis does not affect corneal densitometry and corneal endothelial cells. However, there is a higher lens densitometric measurement in Primary myelofibrosis compared to the control healthy group.

    Investigation of the cause, anatomical localization of perforations and demographic characteristics in patients with perforating eye injuries
    (2020) Kaya, Huseyin; Yilmaz, Ugur
    Aim: To investigate the clinical features of open globe injuries treated in our clinic.Material and Methods: 65 eyes of 65 patients who were operated for open globe injury between 2016-2018 in Pamukkale University ophthalmology clinic were retrospectively analyzed. File records; age, sex, injury with which eye was affected, the cause and type of injury, biomicroscopic examination findings were recorded. The type of injury was classified as corneal, scleral and cornea-scleral according to localization.Results: 65 eyes of 65 patients were included in this retrospective study. 65 of 30 eyes were right eye and 35 eyes were left eye. The mean age of the patients was 41.33 ± 23.52 years. 15 (23.0%) of the patients were under the age of 18 and 50 (67%) were adults. 23 (35.4%) women and 42 (64.6%) men were included in the study. The causes of eye trauma are shown in Table 1. 35 (53.8%) of the injuries were classified as blunt and 30 (46.2%) were classified as penetrating injuries.Conclusion: Open globe injuries, which is one of the most important causes of preventable blindness, is an important public health problem, we think that necessary precautions should be taken and public awareness should be taken in this direction.
