    (2014) Gungor, Sirel Gur; Akkoyun, Imren; Reyhan, Nihan Haberal; Yesilirmak, Nilufer; Yilmaz, Gursel; https://orcid.org/0000-0001-6178-8362; https://orcid.org/0000-0002-2860-7424; https://orcid.org/0000-0001-9852-9911; https://orcid.org/0000-0002-8632-2873; https://orcid.org/0000-0002-2589-7294; 24912003; AAD-5967-2021; AAK-7713-2021; AAK-4587-2021; AAD-7299-2020; AAK-6987-2021
    Purpose: To evaluate the choroidal thickness in patients with ocular sarcoidosis during quiescent phase using enhanced depth imaging optical coherence tomography (EDI-OCT) and comparing it with normal subjects. Method: Eighteen eyes of 9 patients with ocular sarcoidosis (8 women, 1 man, mean age: 59.12 +/- 18.49 years) were enrolled in this study. Their subfoveal choroidal thickness was measured using EDI-OCT in the quiescent phase of uveitis, and compared with the age-, sex-, and spherical equivalent-matched normal subjects (6 women, 3 men, mean age: 59.6 +/- 14.22 years). Results: The mean subfoveal choroidal thickness was 281.76 +/- 88.1 mm in patients with sarcoidosis and 342.32 +/- 71.02 mm in controls. Significant differences were found at points between nasal 1500 mm and temporal 1000 mm to the fovea between patients and control group (p = 0.002, at fovea). Conclusions: Patients with ocular sarcoidosis had thinner choroids in the quiescent phases when compared to normal subjects.

    Circumferential Ciliary Body Cysts Presenting as Acute Pigment Dispersion and Ocular Hypertension
    (2018) Sezenoz, Almila Sarigul; Gungor, Sirel Gur; Kiratli, Hayyam; Akman, Ahmet; 0000-0002-7030-5454; 0000-0001-6178-8362; 0000-0003-2100-4740; 28914584; AAJ-4860-2021; AAD-5967-2021
    Purpose: To report a case of circumferential neuroepithelial cyst of the ciliary body presenting with pigment dispersion (PD) and ocular hypertension. Case report: 48-year-old female patient presented with a complaint of pain in the left eye. On examination, visual acuity of the left eye was 0.9, and the intraocular pressure was 48 mmHg. Biomicroscopic anterior segment examination of the left eye revealed 4+ pigmented cells in the anterior chamber. Active PD from the pupillary region at 11 o'clock was noticed at the time of the examination. Ultrasound biomicroscopy demonstrated 360o cystic lesions of the ciliary body in the left eye. The patient was diagnosed as neuroepithelial cyst of the ciliary body. Conclusion: Our case is unique as it is the first case of circumferential neuroepithelial ciliary body cyst presenting with acute PD and ocular hypertension.

    Quantitative Evaluation of Macular Vessel Density Measurement by Optical Coherence Tomography Angiography in Patients with Inactive Ocular Sarcoidosis
    (2023) Gungor, Sirel Gur; Sezenoz, Almila Sarigul; Adwan, Noor; Gokgoz, Gulsah; Aksoy, Mustafa; Karadas, Mustafa; Colak, Meric; 0000-0001-6178-8362; 35404733; AAD-5967-2021
    Purpose To evaluate the macular vessel density (VD) in inactive ocular sarcoidosis (OS) and investigate the relationship between VD and both disease duration and visual acuity (VA). Methods This cross-sectional study was performed at a tertiary hospital. The macular VDs of patients with OS were obtained using optical coherence tomography angiography and compared with healthy subjects. Results Deep whole image macular VD (WI-MVD), parafoveal, and perifoveal VDs were lower in OS group (p = .01, p = .01, p = .02, respectively). Negative correlation between disease duration and both superficial and deep WI-MVD, parafoveal, and perifoveal VDs was obtained (for all p < .05). There was a positive correlation between VA and superficial VD (p < .001, r = 0.848 for WI-MVD). Conclusion OS affects deep VD significantly. Changes in superficial VD affect VA more. Disease duration is an important factor affecting macular VD.
