Item Choroidal Thickness in Ocular Sarcoidosis during Quiescent Phase Using Enhanced Depth Imaging Optical Coherence Tomography(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-6987-2021Purpose: 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.Item 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-5967-2021Purpose: 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.Item 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-5967-2021Purpose 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.Item Characteristics of uveitic glaucoma in Turkish patients(2020) Tekeli, Oya; Elgin, Ufuk; Takmaz, Tamer; Eksioglu, Umit; Bas, Zeynep; Yarangumeli, Alper; Karakurt, Ahmet; Evren Kemer, Ozlem; Mumcuoglu, Tarkan; Aktas, Zeynep; Akman, Ahmet; Bayer, Atilla; 32799547Purpose: To evaluate the prevalence of uveitic glaucoma (UG) in the Turkish population and investigate the primary underlying diseases. Methods: This multicenter, cross-sectional, prospective study included patients who presented to the glaucoma units of 10 tertiary ophthalmology departments in Ankara, Turkey from 15th March to 16th May 2015 and fulfilled the criteria of UG. Patients were inspected for age, sex, medical history, best corrected visual acuity, biomicroscopic findings, intraocular pressure values, and visual field results. Results: During the study period, 4604 eyes of 2541 patients with glaucoma were screened and 145 eyes of 104 patients (4.1%) were identified as having UG. One hundred and thirty-four eyes (92.4%) had open-angle glaucoma and 11 eyes (7.6%) had closed-angle glaucoma. The mean patient age was 47 +/- 16 (6-90) years. Idiopathic uveitis (54 eyes), Behcet's disease (26 eyes), Fuchs heterochromic cyclitis (21 eyes), Herpes Simplex virus infectious uveitis (14 eyes), and ankylosing spondylitis (six eyes) were the leading types of uveitis associated with glaucoma. Acute anterior uveitis was the most common type of uveitis diagnosed in 72 patients (105 eyes), whereas 21 patients (27 eyes) had panuveitis, eight patients (nine eyes) had intermediate uveitis, and three patients (four eyes) had posterior uveitis. The need for surgical intervention was 37.2% among all cases and the most common surgery was trabeculectomy in 45 eyes. Conclusion: UG is a vision-threatening complication commonly seen in patients with uveitis. This study demonstrates the epidemiological features and underlying etiologies of UG in the Turkish population. The most common primary causes of UG were Behcet's disease and Fuchs heterochromic cyclitis.
