Patient Understanding of Diabetic Retinopathy Limited

Patient understanding of diabeticretinopathy is rather limited according to a recent study exploring patients’ knowledge of the risk factors, cause and controllability of their own diabetic retinopathy. The study revealed considerable misunderstanding, gaps in knowledge and potentially damaging beliefs about the cause and treatment of diabeticretinopathy.

Focus groups and interviews were conducted with 57 patients with diabetic retinopathy (DR), nearly half of whom had severe proliferative DR-a serious complication. Most of these patients had also undergone laser treatment. At the conclusion of the study, patients were found to have had a reasonable understanding of the basic risk factors for DR, such as diabetes control, but they were less clear about specific risk factors such as blood pressure and lipid control. Most patients attributed their DR either to poor diabetes control or to failings of the health care system, rather than having a basic understanding of the small blood vessel disease including circulatory and oxygen deprivation that results from the damaged blood vessels in the retina. Some patients believed that their DR was a result of health aspects beyond their control or environmental factors, whereas others were unsure about the cause.

Improving patients' understanding of the major risk factors for DR as well as helping them have a better understanding of the causes of diabetic retinopathy and being able to grasp expectations of realistic outcomes of laser treatment may improve patients' coping mechanisms, adaption to disease and ocular outcomes.

Dry Eye Common after Cataract Surgery

Developing a dry eye after cataract surgery is actually pretty common especially since the incidence of mild to moderate dry eye in a cataract aged population prior to cataract surgery-and exacerbated by cataract surgery makes dry eye a rather frequent complaint among this group.

According to the Prospective Health Assessment of Cataract Patients Ocular Surface (PHACO) Study some 60-75% of a cataract aged population had a meaningful deficiency in their tear film testing. Further, although cataract surgery is quite friendly to the cornea, it does require and incision which has the potential to temporarily interrupt corneal nerves responsible for reflex tearing and tear film integrity as well. This along with some of the solutions used during the cataract procedure can indeed result in a dry eye. The symptoms one might experience could include fluctuations of vision, dryness, grittiness, tearing, burning and a general tiredness as well as an overall sandy feeling. 

The good news is that for the vast majority of patients with dry eye there are potentially helpful treatment options that include specialized artificial tear lubricants and solutions, tiny punctal plugs to help you retain tears and prescription medication that stimulates production of your own tears. In addition there are more technological approaches such as lasers and other methods to treating underlying blepharitis, eyelid gland problems or eyelid inflammation that can contribute to dry eye as well.

Eye Health Problem Concerns at High Altitude

High altitude activities sometimes pose a bit of concern to those who might be at risk for certain eye problems such as corneal swelling problems and angle closure glaucoma. Have you ever been concerned about your eye health at high altitude? Sometimes patients who spend a great deal of time in high altitudes-skiing, mountain climbing or even just touring-are concerned about the effects on their eyes, especially if they have some other eye problems or diseases related to hypoxia or not enough oxygen.

Researchers from the Tübingen High Altitude Ophthalmology (THAO) reporting in the journal Investigative Ophthalmology & Visual Science examined the effect of high altitude on the cornea and on the drainage angle of the eye-a key anatomical landmark for predicting narrow angle glaucoma risk. Using the advanced imaging technique of Optical Coherence Tomography (OCT) they studied corneal thickness changes and the depth and shape of the “anterior chamber angle” to determine the effects of high altitude. In normal healthy eyes, they found that a significant degree of reversible corneal swelling occurred with increasing altitude but no effect was noted on the size or shape of the eye fluid drainage angle. Since the corneal swelling was reversible it was not damaging. However, for patients with corneal dystrophy problems such as Fuchs Dystrophy, any endothelial dystrophy or compromise there may be some delay in the deswelling of the cornea. For patients who might be at risk for narrow angle glaucoma, the researchers reported that no change in angle depth or shape occurred at the higher altitudes-and thus there was no increase in angle closure glaucoma risk.

July 4th Fireworks Eye Safety Precautions

Taking some common precautions this July 4^th regarding fireworks eye safety can go a long way to preventing eye injury and potentially catastrophic vision loss. To enjoy the fireworks this July 4^th, it’s best to leave their use and display to professionals. Eye safety is pretty critical with fireworks displays as we know that eye injuries are the second most frequent injury we see from emergency room each July 4^th weekend. The best defense against kids suffering severe eye injuries and burns is to not let kids play with any fireworks. Do not purchase, use or store fireworks of any type. Protect yourself, your family and your friends by avoiding home use of fireworks and attend only authorized public fireworks displays conducted by licensed operators, but be aware that even professional displays can be dangerous.

If an eye accident does occur, there are a few things you should know:

·         Do not rub the eye.

·         Do not attempt to rinse out the eye. This can be even more damaging than rubbing.

·         Do not apply pressure to the eye itself-but protecting the eye from further contact with any item, including the person’s hand.

·         Do not stop for medicine! Over-the-counter pain relievers will not do much to relieve pain. Aspirin (should never be given to children) and ibuprofen can thin the blood, increasing bleeding. Take the person to the emergency room at once.

·         Do not apply ointments or drops. They may not be sterile and may make the area around the eye slippery and harder for the doctor to examine.

Once you are seen in the emergency room please feel free to have them call Northwest Indiana Eye &Laser Center at 866-522-3937 as we always have an eye doctor “on call” to provide consultation and continued care for you.
