Purpose: The purpose of this study was to compare autoregulation of retinal arteriolar and venular blood flow in patients with glaucoma, glaucoma suspect participants, and control participants using erythrocyte mediated velocimetry.
Methods: This prospective cohort pilot study included 7 eyes of 5 participants with glaucoma, 15 eyes of 8 glaucoma suspect participants, and 11 eyes of 6 control participants. Mean erythrocyte velocity in retinal arterioles and venules was measured using erythrocyte mediated velocimetry at room air and after oxygen supplementation.
Introduction: The dexamethasone (DEX) implant is an FDA approved treatment for diabetic macular edema, non-infectious posterior uveitis, and macular edema secondary to branch or central retinal vein occlusions. We describe a case of anterior chamber (AC) migration of a DEX implant in a patient with a history of congenital glaucoma and perform a review of the literature on this particular complication, summarizing the common risk factors, subsequent complications, and management options.
Case Description: A 46-year-old female with a history of congenital glaucoma, status post cataract extraction with insertion of intraocular lens, pars plana vitrectomy, and Baerveldt tube implant in the left eye was referred for post-operative cystoid macular edema (CME).
Article Synopsis
- Changes in retinal blood flow could play a role in glaucoma and similar eye diseases.
- Erythrocyte mediated velocimetry (EMV) is a new technique that uses indocyanine green dye to measure the speed of erythrocytes in the retinal microvasculature.
- The study involved 23 sessions showing the average erythrocyte speeds in arteries (7.17 mm/s) and veins (6.05 mm/s), with low variability in the measurements, suggesting EMV could be a reliable method for studying blood flow in the retina.
Purpose: Nonmedical out-of-pocket cost to both patients and their companions of office visits for routine glaucoma care has not been extensively studied in the United States. We evaluate potential key predictors of patient expenditures that are critical to assessing the cost-effectiveness of glaucoma health care delivery.
Materials And Methods: In total, 300 patients responded to the survey in 3 clinics in 2 clinical practice settings.
Purpose: To identify characteristics of ophthalmologists and practices who refer glaucoma patients to low vision services (LVS).
Materials And Methods: An online survey was distributed to members of the American Glaucoma Society. The survey queried demographics of responders and their clinical practices, criteria and barriers to referral to LVS.
