    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.

    Microperimetry, Humphrey field analyzer, and optical coherence tomography in detecting glaucoma: a comparative performance study
    (2022) Akar, Serpil; Tekeli, Oya; Ozturker, Zeynep Kayaarasi; 35023012
    Purpose To evaluate and compare the diagnostic performance of microperimetry (MP), visual field (VF) 10-2 and 24-2 tests, and spectral-domain optical coherence tomography (SD-OCT) in primary open-angle glaucoma (POAG). Methods The study consisted of 35 POAG and 42 control eyes were enrolled in this prospective study. Eligible participants were >= 50 years old. VF assessments were carried out using the Humphrey field analyzer (HFA) and Macular Integrity Assessment. Optic nerve head (ONH), retinal nerve fiber layer thickness (RNFLT), and ganglion cell inner-plexiform-layer thickness (GCIPLT) were measured by SD-OCT. Areas under the receiver operating characteristic curves (AUC) and sensitivities at 95% specificity were calculated for each parameter. Results HFA 24-2 had the largest AUC value among the functional parameters to differentiate POAG from control eyes [AUC: 0.950 (0.906-0.994), sensitivity at 95%:60]. HFA 24-2 showed a significantly better performance than the 10-2 test (p = 0.036). Among the SD-OCT structural parameters, minimum GCIPLT had the largest AUC value to differentiate POAG from control eyes [AUC: 0.952 (0.905-0.999), sensitivity at 95%:80]. In comparison of the functional and structural parameters, HFA 24-2 showed a significantly better performance than the 10-2 test (p = 0.036). In macular parameters, minimum GCPLT performed significantly better than HFA 10-2 (p = 0.015) in detecting POAG. There was no statistically significant difference between the comparative diagnostic performance of the RNFL, ONH, HFA, and MP (p > 0.05 for all comparisons). Conclusion The structural and functional test results revealed that GCIPLT measurements had the highest diagnostic performance in detecting POAG. HFA 24-2 test performed better than 10-2 test in distinguishing glaucoma from healthy eyes. MP showed a similar performance with HFA 10-2 and may be considered a complementary diagnostic tool.
