What actually is Retinitis Pigmentosa?
Retinitis Pigmentosa (RP) refers to a group of diseases, which causes a slow, but progressive vision loss. It is a genetic disorder that affects the ability to respond to light.This inherited disease causes a slow loss of vision, beginning with decreased night vision and loss of peripheral (side) vision and eventually results in blindness.
Causes: Retinitis pigmentosa is often hereditary (runs in families). If you or your partner has retinitis pigmentosa, there may be up to a 50 percent chance that you will pass it on to your children. Ask an ophthalmologist about genetic counseling if you are planning to have children.
- Slow loss of vision
- Beginning of decreased night vision
- Loss of peripheral vision
- Difficulty in identifying colours
Diagnosis: If you have poor night vision or a loss of side vision or if there is a history of retinitis pigmentosa in your family, your ophthalmologist will conduct a comprehensive eye exam to determine if you have retinitis pigmentosa. Your ophthalmologist will dilate your eyes to look at the back of them for signs of disease.
Treatment: Currently there is no known cure for retinitis pigmentosa. However, research has shown that vitamin A palmitate may slow the progression of certain forms of RP. Your ophthalmologist can advise you about the risks and benefits of vitamin A palmitate and how much you can safely take. Taking too much vitamin A palmitate can be toxic, and evidence of vitamin A palmitate effect on RP progression is not substantial.
Another recommendation for slowing vision loss from RP is to wear sunglasses to protect your retina from harmful ultraviolet (UV) light.
Retinal prosthesis is also an important area of exploration because the prosthesis, a man-made device intended to replace a damaged body part, can be designed to take over the function of the lost photoreceptors by electrically stimulating the remaining healthy cells of the retina.
Anything that enters the eye from outside and causes inflammation or irritation, or even an abrasion, among varied other problems, can be termed as a foreign body. This foreign body usually ends up having an effect on the conjunctiva or the cornea. While the cornea is the outer layer that protects the eye, the conjunctiva is the membrane that covers the white portion of the eye. Here are a few ways for understanding and treating the entry of foreign objects into the eye.
Symptoms: To begin with, one must understand the symptoms so as to recognise the problem. A feeling of pressure or discomfort will be experienced by the patient, who will feel as though something is preventing him or her from shutting the eye properly. At the same time, too much tear formation and pain in the eyes will also point at the entry of the foreign object while redness and bloodshot eyes are also a common sight at such instances. The patient may be forced to blink at more than the normal rate, while glares of light will create pain and discomfort.
Causes: There are many kinds of foreign objects that can enter the eyes including fine substances like saw dust, dirt, grime, dust, sand and even the dust of cosmetics. Also, eye lashes, dried mucus, shards of glass and metal particles may enter the eyes and create an emergency situation. When the wind sweeps debris up, it may fall into a person’s eyes and settle there.
Prompt Action: As soon as you feel like something has entered your eye and does not seem to be leaving it even after continuous blinking, then you will need to see a doctor in the Emergency Unit of your hospital. Do not rub your eyes at all, as the foreign object may cause cuts inside and lead to bleeding and other complications. You must take special care to notice whether or not the object in the eye is sharp and is preventing you from shutting your eye properly, in which case immediate medical intervention and diagnosis will be required.
Treating the Foreign Object: With the aim of removing this object, the doctor may administer anaesthetic drops before using a fluorescein dye to find out what kind of object has entered. A moist cotton swab will be used for removal and an antibiotic ointment will be prescribed for any cuts. Acetaminophen can treat the pain while a CT scan can investigate any intraocular object.
You can also use a wet cloth to rinse and remove the object at home, but blurry vision and pain must be taken to an ophthalmologist immediately. In case you have a concern or query you can always consult an expert & get answers to your questions!
In today’s world, most of the work that you do, is on your computer. With an increasingly digitized world, computers can’t be replaced. Though they have made your work easier, they do come with certain disadvantages as well. The rays emitted by a computer screen can be harmful to your eyes, if exposed for an extended duration.
It is important that you take certain precautionary measures to protect your eyes:
1. Wash your eyes: Wash your eyes on a regular basis; it facilitates cooling and relaxation of the eyes. Make it a routine to wash your eyes at least 5 to 6 times in a day.
2. Get computer glasses: Use computer glasses to protect your eyes as they help to minimize the effect of radiation from the screen. If you work for long hours in front of the computer, then you should consider getting a pair of computer glasses.
3. The position of your screen: The screen should ideally be positioned at an arm’s length and the viewing angle of the monitor should be around 35 degrees. Make sure you position your chair accordingly, keeping these tips in mind.
4. Eye exercise: You should exercise your eyes to reduce the strain and relax your eyes. Follow the 20-20 rule wherein after working on your computer for 20 minutes, you redirect your gaze to an object that is around 20 feet away. This helps your eye muscles to relax and thus, improves your eye health.
5. Don’t work at a stretch: Take breaks in between your work sessions to reduce fatigue in your eyes. Constantly staring at a screen for an extended amount of time can cause problems in your eye. Take 2 minute breaks for every 30 minutes you spend working on your computer. This helps to reduce the strain on your eyes also helps to release tension in the muscles of the neck and back.
6. Blink more than usual: Blinking moistens your eyes and causes tear production which does not allow the eye to suffer from dryness. It also prevents eye irritation and helps in clearing out dirt from the eyes.
Eye fatigue is a condition where the eyes are constantly tired and in some amount of pain as well. The other symptoms of this condition can also include swelling, burning and itching. Other ailments and conditions in the body like computer vision syndrome and others can cause this condition as a side effect and it should be referred to an ophthalmologist at the earliest for treatment. So what else do we know about tired eyes or eye fatigue? Here are our list!
Causes: Usually, this condition may be caused by activities that require the constant movement and focus of the eyes for tasks like reading, writing, focusing on the glare and flicker found in computer screens or on smartphones, and more. Also, driving for a long time and exposing the eyes to too much sunlight can lead to this condition. Video games and handheld devices may also lead to the same. Also, the presence of more serious ailments in the body as well as computer vision syndrome that hits roughly 50 to 60% of workers who use computer screens on a daily basis and for long hours, can lead to this condition. Lack of sleep and a poor diet that does not have plenty of nutrients can also cause this condition and other related symptoms.
Symptoms: There are many symptoms of this condition including redness, itching, burning, swelling, watery eyes and much more, which will leave the eyes feeling tired. Also, blurred or cloudy vision may be experienced by patients for whom this condition has become more severe. The patient will also end up facing difficulty when it comes to focusing or driving for long periods of time, and headaches may take over after a few hours of reading or computer screen times. Also, related symptoms include acute pain and dull aches in the neck and shoulders which can trickle down to the upper back region.
Treatment: The best treatment for this condition is with the help of lifestyle changes like cutting down your working hours and taking frequent breaks. Also, you could place your computer screen at least 20 to 26 inches away from your face while you are working so that your eyes are at a more comfortable distance and do not get affected too easily. You must also try and limit your screen time in terms of hand held device usage. A doctor may also carry out an eye exam and prescribe artificial tear inducers or bifocal lenses to deal with the problem.
Persistent eye fatigue must be checked by an ophthalmologist who will arrive at a proper diagnosis and treatment. In case you have a concern or query you can always consult an expert & get answers to your questions!
Redness, itchiness and watery eyes are common symptoms of eye allergies. Pollen, mold, dust and pet dander are common allergens that trigger such allergies. Other triggers include adverse reactions to cosmetics and eye medication such as eye drops. Being allergic to certain food items rarely causes eye conditions such as itchiness or excessive tearing. When the surface of the eye is exposed to allergens, it releases histamines. This causes itchiness and makes the eye red and watery.
However, sometimes these can also be symptoms of a larger problem. Itchiness in the eyes and excessive tearing can also be a symptom of conjunctivitis or caused by eye disorders like dry eyes and blepharitis. Ironically,dry eyes is the most notorious factor amongst the above. Watery eyes could also be caused by clogged tear ducts or eyelids that turn inwards or outwards.
If your eye feels itchy or is persistently watery, you must consult an eye doctor. To correctly diagnose the condition and recognize the symptoms triggering it, he will conduct a thorough eye exam and discuss your medical history and lifestyle. If the condition is triggered by an allergy you might also require blood tests for allergies. This will decide your course of treatment. A few tips that could help are:
The best way to keep your eyes healthy is to limit their exposure to factors that could irritate it. Avoid going outdoors during the pollen season especially if it is windy. Wearing wraparound sunglasses can also help create a barrier between your eyes and the allergens. Within the house, ensure that your air filters in the air conditioner are cleaned regularly.
Switch to spectacles or consider lasik surgery if you wear contacts regularly and often suffer from eye allergies. Alternatively you could switch to daily disposable lenses to avoid the buildup of airborne allergens on the surface of the lenses.
Non prescriptions eye drops that help lubricate the eyes are easily available over the counter and can help relieve itchiness. This can also keep your eyes from drying out and thus prevent watery eyes.
The histamines released by the body on contact with an allergen dilute blood vessels and make then abnormally permeable. Antihistamines reduce these reactions by not allowing the histamines to attach themselves to cells in the body. Antihistamines can take a while to react and can make you feel drowsy. Hence it is advisable not to take them when operating heavy machinery or driving.
