What is Retinitis Pigmentosa?
Retinitis Pigmentosa is a genetic disorder that affects the cells within the retina. These photoreceptor cells produce essential proteins that are required in order to see. Photoreceptor cells are responsible for color visualization, clarity of vision, and vision in the central visual field. These cells are found in retinal tissue and functions as a visual phototransduction i.e., it converts light into electrical signals for the stimulation of biological processes of the visual system. This genetic mutation sometimes makes these photoreceptor cells unable to produce this protein or create a protein that is unusable. This results in degeneration of the rods and cones in your eye. Photoreceptor cells consist mainly of three types, rods, cones and ganglion cells. Rods and cones are acting in contributing visual information to the eye for the representation of the visual sight. Retinitis Pigmentosa is rare and is estimated to affect about 1 in 4000 individuals.
What are the symptoms?
The early stage of RP is indicated by degeneration of the photoreceptor rod cells which results in decreased electrical signals for visualization, loss of night vision, gradual loss of peripheral or side vision, loss of central vision, problems in color vision and can eventually lead to blindness after several years. Sensitivity to bright light, sight difficulty in darkness and vision loss are commonly seen in patients affected by Retinitis pigmentosa.
What can you do?
If you are experiencing any of these symptoms it is advised to make an appointment with our physicians; Dr. James Khodabakhsh or Dr. John Hofbauer at Beverly Hills Institute of Ophthalmology. Next, it is necessary to get a diagnosis. This can be done through Electroretinogram (ERG) testing, visual field testing, or genetic testing. If diagnosed with Retinitis Pigmentosa there are many services available to those experiencing vision loss, these services help maintain independence.
LASIK is a great option for many athletes. The inconvenience of glasses or contacts can be eliminated through LASIK surgery. Without these annoyances, athletes can focus on the game.
One consideration that many athletes may have when looking into LASIK surgery is, how long until I can return to my sport?
While it depends on the type of surgery you had, and how severe your eye condition was prior to surgery, there are a few basic rules we suggest for all patients to follow. For the first 48 to 72 hours, we request that a patient shouldn’t rub their eyes or do anything that puts pressure on them. We also recommend avoiding anything that causes sweat to enter the eye.
After 72 hours, light exercise is allowed such as going to the gym, playing tennis or golf, but all with caution. As for more active sports, patients are normally allowed to play again after a little more than a month.
Damage to the eye after LASIK can result from pressure, trauma, or contaminants. This is why recovery is essential in helping reduce the risk of infection or damage to the corneal flap.
For athletes, having to deal with glasses in a contact sport is out of the question and the sweat and dirt of other sports make contacts extremely difficult. Of the professional athletes who have had LASIK surgery, professional male and female golfers of all ages make up a large percentage but other famous athletes have as well.
If you are looking to improve your game and overall enjoyment of your favorite sport, consider LASIK surgery. From the recreational weekend warrior to a professional athlete, many sports enthusiasts can benefit from a LASIK procedure.
Consider scheduling a meeting with Dr. James Khodabakhsh or Dr. John Hofbauer to see if LASIK is right for you.
Improving your vision and protecting your eyesight starts with the food on your plate. Nutrients such as omega-3 fatty acids, lutein, zinc, and vitamins C and E may enhance your chances to ward off age-related vision problems such as macular degeneration (AMD) and cataracts.
Regularly eating these foods can help lead to good eye health:
♣ Green, leafy vegetables such as spinach, kale, and collards
♣ Salmon, tuna, and other oily fish
♣ Eggs, nuts, beans, and other non-meat protein sources
♣ Oranges and other citrus fruits or juices
♣ Oysters and pork
Another good food is carrots as the food contains vitamin A needed for good vision. Another benefit to eating a well-balanced diet also helps you maintain a healthy weight, which makes you less likely to get obesity-related diseases as type 2 diabetes. Diabetes is the leading cause of blindness in adults.
To create a healthy diet, it is just as important to look at what to leave out of your daily diet. Caffeinated beverages such as coffee, soft drinks, regular tea and any caffeinated herb tea. Sugar is important to consume only in moderation and instead satisfy your sweet tooth by eating fruits which provide natural sugars that the body can easily deal with.
Good nutrition is important for healthy vision, but can’t stand on its own. A truly healthy lifestyle involves a healthy diet as well as providing exercise, fresh air with ample rest and sleep.
Dry eye syndrome is a common cause of eye irritation, mainly affecting older people. Artificial tears, gels and soothing ointments usually ease symptoms. Dry eye syndrome or simply dry eyes occurs when there is a problem with the tear film that normally keeps the eye moist and lubricated.
Dry eye syndrome can affect anyone, but it becomes more common with increasing age. Dry eyes affect about 15 to 35 in every 100 people or possibly as many as a third of older people and women are affected much more often than men. One of the big contributing factors with the aging process is that people tend to make fewer tears, as they get older. In particular, some women notice dry eyes developing after menopause. Another cause is having a low blink rate, often combined with opening your eyes wider than normal due to spending a long time looking at a computer or watching television.
The symptoms of dry eyes include eyes feeling gritty or burning and slight blurring of vision from time to time. Also, a person may feel discomfort when looking at bright lights and if a contact lens wearer can start to find wearing them causes discomfort.
A BHIO physician can usually diagnose dry eyes from the symptoms and perform a test to confirm the diagnosis of dry eyes. The treatment for dry eyes is usually eye drops and gels. These are good at relieving the symptoms. More information is available at Beverly Hills Institute of Ophthalmology or www.90210eyes.com
