Stroke Warning: Retinal Artery Blockage!

Retinal Artery Blockage May Warn of Impending Stroke A certain retinal vessel disease may be a warning of an impending stroke! When an artery or vein in the retina becomes blocked or “occluded” it can be a sign of more serious health issues that need to be looked-quickly! A central retinal artery occlusion (CRAO) is a disease of the eye where the flow of blood through the central retinal artery is blocked. Patients suffering from a central artery occlusion experience a sudden, severe, painless loss of vision in one eye. While there can be several different causes of the blockage, most often a central retinal artery occlusion is caused by unhealthy carotid arteries which supply the head and neck with oxygen. Unhealthy carotid arteries are those that have atherosclerosis, are narrowed and filled with a waxy fatty substance that forms plaques that can break off and end up in the retinal circulation.

Glaucoma: Pregnancy, Labor & Eye Pressure

Pregnancy, Labor & Eye Pressure: What You Need to Know!
What could pregnancy, labor and your eye pressure have to do with one another?  For the clear majority of “new moms to be” the thought of their upcoming labor can cause them to voice concerns about their physical as well as emotional wellbeing. Typically, your obstetrician will be a sound source of information about what to expect in terms of pain, discomfort and how they will help you manage the physical discomfort and stress of labor. From time to time we have a patient who is pregnant and who has a family history of glaucoma or is perhaps “ocular hypertensive,” meaning that they have had a high intraocular pressure (IOP) measurement as part of their annual routine eye exam who shares their concern about the physical stress of labor and if there is any chance of eye and optic nerve damage during delivery. Fortunately, recent data from a study we reviewed in the Journal of Glaucoma showed us that eye pressure and blood flow into the optic nerve during the various stages of vaginal labor are not changed and there is no increased risk to those who have a family history of glaucoma or high eye pressure. Mom’s to be can put this fear to rest!

If you are pregnant and have a family history of glaucoma or have been told that you at risk for glaucoma due to a high eye pressure, please be reassured that labor and delivery will not expose you to greater risk. It is important however to continue your regular eye exams-even during pregnancy-and especially if you experience any changes in your vision or general eye health!
