Background: Age-related macular degeneration (AMD) is a leading cause of visual loss among the elderly. A key cell type involved in AMD, the retinal pigment epithelium, expresses a G protein-coupled receptor that, in response to its ligand, L-DOPA, up-regulates pigment epithelia-derived factor, while down-regulating vascular endothelial growth factor. In this study we investigated the potential relationship between L-DOPA and AMD.

Patients with records of trabeculectomy and/or tube shunt procedures were identified, and all cases of "definite" (ie, properly coded) and "suspected" (possibly miscoded) postoperative suprachoroidal hemorrhage occurring within 3 months of their glaucoma filtration procedures were captured along with the surgical interventions used for this condition.

Chronic granulomatous disease (CGD) is a rare primary immunodeficiency disease that has been reported to present with various chorioretinal findings, predominantly in men. We report a case of a 17-year-old girl with a known diagnosis of CGD referred to the ophthalmology clinic for evaluation of an inflamed pingueculum. Upon clinical examination and ophthalmic imaging, high-quality montage fundus photographs demonstrated a wide array of bilaterally asymmetric chorioretinal findings known to be characteristic of the ophthalmic manifestations of CGD, including chorioretinitis and focal subretinal granuloma.
