The usefulness of OCT as a diagnostic tool to differentiate Parkinson-s disease (PD) from other tremor diseases, remains unknown. We aimed to evaluate morphological changes of the retina in patients with PD, essential tremor (ET), essential tremor-Parkinson-s disease (ET-PD) using OCT. Forty-two eyes of 21 patients with PD, 24 eyes of 12 patients with ET, 24 eyes of 12 patients with ET-PD and 44 eyes of 22 age-matched healthy controls were included in the study. All participants underwent detailed neurological and ophthalmological examination. Measurements in all quadrants of macula and retinal nerve fiber layer (RNFL) thickness using OCT were recorded. There was no significant difference among the groups regarding age, sex. The average RNFL thickness was thinner in PD patients than that of ET (p = 0.032). The RNFL thickness in superior quadrant was lower in PD group compared with the ET and control group (p = 0.001, p = 0.016). Significant differences were observed in most of the macular thickness parameters excluding foveolar and foveal thickness (p = 0.865, 0.394). Correlations were found among several OCT parameters and disease duration or severity in all patient groups (p > 0.05). Retinal alterations were found in PD patients compared to ET. However, no significant retinal changes were detected by OCT in patients with ET and ET-PD compared to controls. According to our data, retinal assessments by OCT do not seem to be satisfactory for differentiation of these disorders.Publication Metadata only Retinal sensitivity improvement after intravitreal triamcinolone acetonide injection for macular edema secondary to branch retinal vein occlusion(2013-01-01) SENTURK, Fevzi; OZDEMIR, Hakan; KARACORLU, Murat; KARACORLU, Serra Arf; Uysal, Omer; ÖZDEMİR, MEHMET HAKAN; UYSAL, ÖMERPurpose: To evaluate the effect of intravitreal triamcinolone acetonide (IVTA) on retinal sensitivity in cases of macular edema(ME) secondary to branch retinal vein occlusion (BRVO). Materials and Methods: Total of 14 eyes of 14 cases of BRVO were included in this prospective study. In each eye, at baseline and 1, 3, and 6 months after IVTA injection, logMAR visual acuity, central 4 degrees retinal sensitivity by MP-1 microperimetry, and optical coherence tomography foveal thickness were assessed. Results: Cases ages ranged from 60 to 79 years (mean 68 +/- 8 years). At 1, 3, and 6 months, the logMAR visual acuity had increased from 0.71 +/- 0.21 to 0.42 +/- 0.21, 0.46 +/- 0.30, and 0.46 +/- 0.27; the mean foveal thickness had decreased from 540 +/- 88 mu m to 254 +/- 51 mu m, 288 +/- 84 mu m, and 280 +/- 91 mu m; and the mean retinal sensitivity had increased from 4.7 +/- 2.5 dB to 7.9 +/- 2.7 dB, 8.2 +/- 3.6 dB, and 8.3 +/- 4.6 dB, respectively. Conclusion: In eyes with ME secondary to BRVO, IVTA injections result in a significant increase in not only the visual acuity but also the central 4 degrees retinal sensitivity in 6 months follow-up.Publication Metadata only Incidence and factors associated with complications of sutured and sutureless cataract surgery following pars plana vitrectomy at a tertiary referral centre in Turkey(2016-09-01) HOCAOGLU, Mumin; KARACORLU, Murat; MUSLUBAS, Isil Sayman; OZDEMIR, Hakan; ARF, Serra; Uysal, Omer; ÖZDEMİR, MEHMET HAKAN; UYSAL, ÖMERAims To evaluate the incidence of and factors contributing to intraoperative and postoperative complications of eyes with previous pars plana vitrectomy (PPV) undergoing phacoemulsification and intraocular lens (IOL) implantation for cataract.Publication Metadata only Ultrasound findings in eyes with stage 5 retinopathy of prematurity(2015-11-01) I, Sayman Muslubas; Karacorlu, M; Hocaoglu, M; Yamanel, C; Arf , S; ÖZDEMİR, MEHMET HAKAN; Uysal, O; ÖZDEMİR, MEHMET HAKAN; UYSAL, ÖMERPublication Metadata only Macular function after intravitreal triamcinolone acetonide injection for diabetic macular oedema(2010-08-01T00:00:00Z) KARACORLU, Murat; OZDEMIR, Hakan; SENTURK, Fevzi; KARACORLU, Serra Arf; Uysal, Omer; ÖZDEMİR, MEHMET HAKAN; UYSAL, ÖMERPurpose:
