Methods: In this cross-sectional study, the number of sections per slide for paraffin-embedded blocks for 100 randomly selected cases where GCA was suspected and those for negative temporal artery biopsies (TABs) were compared with the number of cross-sections per specimen for eight positive-TABs. All aforementioned examinations were conducted at our center from 2012 to 2016.
Purpose: This study evaluates the outcomes of ruthenium-106 (Ru-106) plaque brachytherapy for vasoproliferative tumors (VPTs) of the ocular fundus in a single referral ocular oncology center.
Methods: The clinical charts of all patients diagnosed with VPT who underwent plaque radiotherapy from 2002 to 2017 were reviewed. Clinical features, types of treatment, outcomes and complications were evaluated.
Purpose: To assess the use of temporal artery biopsy (TAB) in diagnosing giant cell arteritis (GCA) and to evaluate patients' clinical and laboratory characteristics.
Methods: We conducted a retrospective chart review of patients with suspected GCA who underwent TAB and had complete workup in a tertiary center in Iran between 2008 and 2017. The 2016 American College of Rheumatology (ACR) revised criteria for early diagnosis of GCA were used for each patient for inclusion in this study.
Purpose: To investigate the effects of fasting on intraocular pressure (IOP), central corneal thickness (CCT), radial peripapillary capillary (RPC) density and retinal nerve fiber layer (RNFL) thickness during Islamic fasting month of Ramadan.
Methods: Twenty-seven healthy fasting volunteers were enrolled. All subjects underwent full ophthalmic examination and optical coherence tomography angiography (OCTA) of both eyes.
To evaluate the safety of subconjunctival injection of doxycycline in rabbit eyes. Eight white New Zealand rabbits were selected. Different concentrations of 250 micrograms (μg), 500 μg, 1000 μg, and 2000 μg in 0.
