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.
Age-Related Macular degeneration is the number one cause of vision loss facing 10 million Americans today. Which is more than cataracts and glaucoma combined. Currently, this disease affects many people living in Beverly Hills, Los Angeles, and throughout Southern California. The disease is caused by deterioration of the central part of the retina. This area, called the macula, lies at the back of the eye and records the images we see. These images are sent through the optic nerve to then be interpreted by the brain. Although this disease is currently incurable there are ways to slow its effects.
Those highest at risk for age-related macular degeneration are over the age of 55, smokers, or those with a family history of AMD. In order to slow the effects of AMD, it is advised to avoid smoking and live a healthy lifestyle. AMD by itself does not lead to complete blindness, with no ability to see. However, the loss of central vision in AMD can interfere with simple everyday activities, such as the ability to see faces, drive, read, write, or do close work, such as cooking or fixing things around the house. It is possible to lower the risk of AMD or slow its progression by eating healthy, exercising, and protecting your eyes from ultraviolet light. For more information about AMD visit your local ophthalmologist.
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.
LASIK is FDA approved for people 18 years and beyond. Many young adults are encouraged to wait until their mid-20s when their prescription is more stable. When it comes down to it, eye surgeons perform laser eye surgery on patients at both ends of the age spectrum. Many young active adults start to notice that many of their friends and classmates are talking about the benefits of LASIK. A laser vision correction procedure can give young people high performance vision without the hassle of eye glasses and contacts. This is combined with the cost savings benefit by avoiding a lifetime of expense for glasses, contacts and solutions.
There is no reason a younger patient should not have the opportunity to see more clearly without having to wear corrective lenses. There are no concrete guidelines on refractive surgery for the younger generation. So, if you are considering LASIK Surgery in your 20’s and 30’s? The first step is to discuss your options with your physician and get a complete annual comprehensive eye exam.

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
Custom LASIK is a laser vision correction procedure that helps your LASIK surgeon further customizes the correction to your individual eyes. LASIK surgeons are able to focus on the quantity as well as the quality of your vision. Custom LASIK surgery, also known as wavefront LASIK or wavefront-guided LASIK, uses 3-dimensional measurements of how your eye processes images to guide the laser in re-shaping the front part of the eye or cornea. With custom LASIK, your eye’s ability to focus light rays is measured, and a 3-D map used in wavefront technology is created that determines irregularities in the way your eye processes images. Information contained in the map guides the laser in customizing the treatment to reshape your eye’s corneal surface so that these irregularities can be corrected. The process for determining a custom LASIK treatment begins with an eye examination and the use of a wavefront device to transmit a safe ray of light into your eye. The light is then reflected back off the retina, out through the pupils and into the device, where the reflected wave of light is received and arranged into a unique pattern that captures your aberrations. All of these visual irregularities are then displayed as a 3-D map, referred to as a wavefront map. This information is then electronically transferred to the laser in wavefront-guided systems, and computer-matched to the eye’s position, enabling the surgeon to customize the LASIK procedure laser treatment to your unique visual requirements. Standard prescriptions for glasses, contacts or traditional LASIK procedures can correct ordinary vision defects such as myopia, hyperopia, and astigmatism. But other irregularities associated with the eye’s optical system could not be addressed until the advent of wavefront and related technology used in custom LASIK.
