What is High Blood Pressure?
High blood pressure, also known as hypertension, can affect your body and eyes in many ways. It is important to know what your blood pressure is and to maintain good control of it.
"Five Stars - My husband and I have been Dr Kim’s patient for over 17 years. She is a compassionate, knowledgeable, detailed oriented doctor with excellent bedside manner. She had saved my husband’s vision from macular degeneration. We all love her and will be her faithful patients forever."- Anonymous / Vitals / Jul 19, 2018
"For the last three years I've been treated by the Retina Consultants of Houston at the Sugar Land location and have been extremely satisfied with the very professional, courteous staff and Dr. Chen. When at the office in the waiting rooms I've spoken with numerous other patients who have all had the same comments of satisfaction. My observations have always been that the staff and doctors work hard to keep patients waiting time at a minimum, while maintaining the excellent quality of care. I would not go any where else."- S.R. / Google / Jun 22, 2018
"Dr. Brown is an excellent surgeon. If you want the best, you have to make a sacrifice. I have been a patient of Dr. Brown, for decades, and I would recommend him to anyone. I would be completely blind if not for Dr. Brown, and God, the Most Holy of Holy."- M.S. / Healthgrades / May 16, 2018
"My left retina had tear in it and I had no clue of what was happening, but was referred to the Retina Consultants of Houston and was blessed with meeting Dr. Wykoff. He repaired my eye while explaining everything in detail and helping me to feel comfortable. Less than a year later my right eye did the same thing but a little worse. Nowadays, I will only let Dr. Wykoff work on me. I am seeing great today and at 58 have zero floaters, etc. This Doctor is the best."- C.P. / Google / Mar 16, 2018

Changes In Your Retina
Changes that can occur in your retina from high blood pressure include:
• Edema and swelling of your retina
• Exudation (fluid leakage) and buildup of protein and lipids in the retina
• Small infarctions of the retina (tissue death due to inadequate blood supply), also known as “cotton wool spots”
• Arteriosclerosis: arteriolar narrowing, artery-vein crossing changes (also known as “AV nicking”), changes in the color of arterioles and in advanced cases, sclerosis (abnormal hardening) of the blood vessels
• Optic nerve swelling and blurred vision
Severe cases of hypertension may result in blockages of the retinal veins or arteries. These blockages of circulation (called occlusions), can cause severe loss of vision or even blindness.
Plan Your Procedure
Inside Your Eyes
Your ophthalmologist or retina specialist can directly see your retinal blood vessels through a comprehensive, dilated eye exam. The appearance of these vessels and your retina are excellent markers of the overall health of your body’s blood vessel system. In fact, the retina is the only place in the body where your physician can directly see your blood vessels. The retina is one of the organs most sensitive to sustained hypertension. Subjected to high blood pressure over time, the retinal blood vessels can become damaged and leak. Contact the doctors at Retina Consultants Houston and schedule your exam today.
