    Fellow-eye asymmetry on optical coherence tomography angiography and thickness parameters in unilateral pseudoexfoliation syndrome
    (2022) Pasaoglu, Isil; Ozturker, Zeynep Kayaarasi; Celik, Selcen; Ocak, Bulut; Yasar, Tekin; 34852056
    Purpose: To investigate inter- eye retinal vessel density and thickness asymmetry in unilateral pseudoexfoliation syndrome and understand its use for the early detection of glaucoma. Methods: Thirty patients with unilateral pseudoexfoliation syndrome were enrolled in our study. Optical coherence tomography angiography macular scans were used measure the retinal vessel density, and optical coherence tomography scans were used to assess the thickness parameters of the peripapillary retinal nerve fiber layer and the macular ganglion cell complex. Inter-eye asymmetry was determined by taking the absolute value of the difference in the vessel density and thickness parameters between the pseudoexfoliation syndrome eye and fellow eye. Results: The mean patient age was 64.20 +/- 7.05 y in the study group. Inter-eye asymmetry in the peripapillary retinal nerve fiber layer thickness and macular ganglion cell complex measurements were significant in the study group (p=0.03 and p=0.001, respectively). The vessel density of the macular superficial inner region was significantly lower in eyes with pseudoexfoliation syndrome than in fellow eyes (p=0.035). However, there was no inter-eye asymmetry in the central and full region macular superficial vessel density of eyes with pseudoexfoliation syndrome and fellow eyes (p>0.05). Conclusions: Retinal vessel density can be evaluated using optical coherence tomography angiography measurements. There was inter-eye asymmetry in the inner region macular superficial vessel density, peripapillary retinal nerve fiber layer, and macular ganglion cell complex thickness of the unilateral pseudoexfoliation syndrome eyes and fellow eyes. Further studies on a larger number of subjects might provide more clarity regarding the relationship between the inter-eye asymmetry of the retinal vessel density and thickness parameters with early detection of glaucomatous damage.

    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; 32799547
    Purpose: 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.
