Increased levels of vascular endothelial growth factor in the aqueous humor of patients with diabetic retinopathy.

Purpose: This study aims to investigate the levels of aqueous vascular endothelial growth factor (VEGF) in diabetic patient groups in comparison to normal subjects, and to correlate elevated VEGF with the severity of diabetic retinopathy (DR).

Materials And Methods: Aqueous samples were obtained from 78 eyes of 74 patients undergoing intraocular surgery and they were examined by the enzyme-linked immunosorbent assay. Color photographs, optical coherence tomography scans, and fluorescein angiography were used to evaluate patients preoperatively.

Bilateral choroidal metastases presenting as acute glaucoma crisis.

We report a case of bilateral choroidal metastasis presenting with acute unilateral glaucoma. Primary tumor was found in the lung and choroidal masses in both eyes. Anterior segment neovascularization causing intraocular pressure elevation was the only presenting sign of metastatic choroidal tumor.

Exacerbation of central serous chorioretinopathy following intravitreal triamcinolone injection.

Background: This report describes a case of central serous chorioretinopathy following intravitreal triamcinolone acetonide injection.

Methods: A 42-year-old man presented with a 4-month history of decreased visual acuity (0.4) in his left eye.

Development of ocular hypertension and persistent glaucoma after intravitreal injection of triamcinolone.

Purpose: This study evaluates intraocular pressure (IOP) elevation secondary to intravitreal injection of triamcinolone acetonide (IVTA) and discusses its management.

Methods: The records of 175 patients who underwent IVTA treatment and regular eye examinations in the period 2003-2006 were reviewed. One hundred and twenty-two of these patients were included in the study, of which 147 eyes that received IVTA (4 mg/0.
