    Comparison of Icare Pro Tonometry and Icare one Tonometry Measurements in Healthy Eyes
    (TURKISH OPHTHALMOLOGICAL SOC) Mayali, H; Sarigül, Ç; Kurt, E; Kayikçioglu, ÖR; Ilker, SS
    Objectives: To compare intraocular pressure (IOP) measurements obtained with the Icare Pro tonometer used in clinical practice and the Icare One self-tonometer. Materials and Methods: Fifty-two eyes of 52 healthy, right-handed individuals with no prior intraocular surgery or ocular trauma, structural ocular pathology, or systemic disease were evaluated. IOP was first measured using the Icare Pro tonometer. The participants were then told how to use the Icare One tonometer and asked to measure their own IOP The results were analyzed statistically using SPSS v.24. Results: Of the 52 healthy participants, 16 (30.7%) were male and 36 (69.3%) were female. Their mean age was 31.6 +/- 6.3 (23-47) years. Mean IOP measured with the Icare Pro was 17.10 +/- 6.2 (11.5-25.2) mmHg, and the mean self-measured IOP with Icare One was 14.01 +/- 3.4 (7-24) mmHg. When the two methods were compared using Levene's t-test, there was a significant mean difference of -3.08 +/- 0.6 (95% confidence interval: -4.39 -1.78; p<0.001). Conclusion: In this study, there was a significant difference between the IOP measurements we made using the Icare Pro and the participants' self-measured IOP using the Icare One, with the latter being relatively lower. This may be related to the fact that the participants were unfamiliar with using the Icare One. Although the Icare One is a promising tool for glaucoma patients to self-monitor their IOP, further studies are needed.

    Is pseudoexfoliation associated with sensorineural hearing loss?
    (RIYADH ARMED FORCES HOSPITAL) Ozturk, F; Kurt, E; Inan, UU; Derekoy, S; Ermis, SS; Asagidag, A
    Objective: To determine the possible relation between pseudoexfoliation (PSX) and sensorineural hearing loss. Methods: This study was carried out in Afyon Kocatepe University, Afyon, Turkey between July 2002 and June 2005. Sixty-three patients who were found to have ocular PSX on routine biomicroscopic examination, and 38 age-matched control subjects were evaluated for evidence of audiometric abnormality. The sum of pure-tone hearing threshold measured at 250-2000 Hz, 2000-6000 Hz, and 250-6000 Hz in each ear was compared with controls for the same frequencies. Results: The mean age of the patients was 68.4 +/- 10.3 years. All patients had PSX affecting at least one eye. Fifty (79.4%) patients with PM and 10 (26.3%) control subjects were found to have hearing loss (p=0.00, chi-square). From the 50 patients with PSX who had hearing loss, 34 patients had bilateral PSX, and 16 patients had unilateral PSX Twenty-nine patients had high frequency hearing loss, while 20 patients had hearing loss in all frequencies. Forty-eight patients with PSX and 7 controls had bilateral sensorineural hearing loss (p=0.030). Conclusion: Sensorineural hearing loss was seen more frequently in patients with PSX in comparison with age-matched control subjects.

    Evaluation of the Effect of Body Position on Intraocular Pressure Measured with Rebound Tonometer
    (TURKISH OPHTHALMOLOGICAL SOC) Mayali, H; Tekin, B; Kayikçioglu, ÖR; Kurt, E; Ilker, SS
    Objectives: It is important to determine variables that influence intraocular pressure (IOP) measurement. This study aimed to evaluate the effect of body position on IOP. Materials and Methods: The study included 52 right eyes of 52 patients who presented to the ophthalmology department of our hospital and had no ocular disease except refractive errors. IOP was measured with an Icare PRO tonometer while patients were in sitting, standing, and supine positions, with intervals of 10 minutes between the positions. Correlations between the results were evaluated using Spearman's correlation analysis and Wilcoxon tests. Results: Thirty-six of the 52 patients were female, 16 were male. Mean age was 31.65 +/- 6.30 (23-47) years. Mean IOP values in the sitting, standing, and lying positions were 17.76 +/- 3.41 (12.70-25.60) mmHg, 17.10 +/- 3.27 (11.50-25.20) mmHg, and 18.46 +/- 4.67 (10.50-29.40) mmHg, respectively. There were no statistically significant differences between measurements taken in the different positions (p=0.112, p=0.472, p=0.071). We observed that there was no relationship between age and body position (p>0.45, p>0.79, p>0.77) or between gender and position (p>0.59, p>0.69, p>0.54). Conclusion: Gender and age had no effect on IOP measured in different body positions. There were also no significant differences between IOP values measured in the different positions. Therefore, we believe the portable Icare PRO tonometer can be used for patients who are confined to bed and will provide IOP measurements that are concordant with values obtained while sitting.

    A multimodal ophthalmic analysis in patients with systemic sclerosis using ocular response analyzer, corneal topography and specular microscopy
    (SPRINGER) Mayali, H; Altinisik, M; Sencan, S; Pirildar, T; Kurt, E
    PurposeTo conduct a multimodal ophthalmic evaluation of systemic sclerosis (SSc) in patients using ocular response analyzer (ORA), Pentacam, and specular microscopy (SM).MethodsThirty-one SSc patients and a group of age- and sex-matched controls were enrolled in this cross-sectional study. Corneal hysteresis (CH), corneal resistance factor (CRF), corneal-compensated intraocular pressure (IOPcc), and Goldmann-correlated IOP (IOPg) were measured with ORA. Anterior chamber depth (ACD), central corneal thickness (CCT), and corneal volume (CV) measurements were obtained using Pentacam. Corneal endothelial cell density (ECD) and CCT were evaluated by SM.ResultsSSc patients had significantly lower CH, ACD, and ECD values compared to the control group (p=0.018;<0.001;<0.001, respectively). There was no significant difference regarding CRF, IOP, CV, or CCT measurements acquired by Pentacam and SM. Regarding CCT, SM and Pentacam showed relatively better agreement in SSc patients.ConclusionsMultimodal imaging can provide more comprehensive and useful information regarding the ocular involvement of systemic diseases. The multimodal evaluation in our study demonstrated that the pathologic effects of SSc may manifest as reductions in ACD, corneal elasticity, and ECD before there are any detectable changes in corneal thickness or IOP.
