Patient Review Highlights
In order to see clearly, the eyes need to be constantly lubricated. This function is performed by small glands located in the eyelids known as meibomian glands. These glands secrete oil onto the surface of the cornea through tiny openings on them. Malfunctioning of this gland can create an excessive amount of oil.
When oil accumulates on the eyelids, it encourages the bacteria present in the eye and the skin around it to multiply leading to inflammation. This condition is known as meibomianitis. Adults are at a higher risk of suffering from this condition as compared to children.
Some of the factors that could trigger meibomianitis are:
- Allergic reactions
- Fluctuation of hormones associated with puberty and adolescence
- Acne and other skin conditions
- Lice or mites on the eyelashes
- Unsanitary contact lens solution
- Contaminated eye makeup
- Certain medications such as isotretinoin for acne that increases bacteria on the eyelids
- However, in some cases, a clear trigger factor may not be identifiable.
Some of the characteristic symptoms of this disease are:
- Dry eyes
- Constant watering from the eyes
- Inflammation and reddening of the eyelids
- Burning sensation in the eyes
- Flaking of skin around the infected eye
- Heightened sensitivity to light
- Excessive blinking
- Crusting of eyelashes
- Blurred vision
- Frequent formation of sties
- Loss of eyelashes or abnormal growth of eyelashes
Regular cleaning of the eyes with warm water and abstaining from the use of contact lenses and eye makeup can help reduce irritation and manage the inflammation. Additionally, the doctor may also prescribe antibiotics or steroids in the form of pills, eye creams or drops. Artificial tears may also be recommended to patients exhibiting dry eye symptoms.
Are you losing your sight day by day? Does it make difficult to see you at night? Is this the onset of Blindness? Get to know about Retinitis Pigmentosa with these tips.
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.
We are surrounded by light from everywhere on all sides. Wherever we go, there is some source of light, be it natural or man made. However, exposure to bright light in excess can cause strain to your eyes and if this is continued your vision quality might decrease.
Here are some ways you can adjust light in order to lessen eye stress and to increase your visibility:
Make adjustments in your workplace:
According to studies, it has been shown that half of people who work in front of computer screens every day suffer from eye strain. Not only the computer, but the entire lighting around your workstation may also be causing damage.
- Reduce the brightness of interior lights. Many offices have bright, fancy interior lighting. Use of light bulbs and fluorescents should be lessened.
- In case of the presence of a window right behind or in front of your work desk, more strain is imposed upon your eyes because of the reflections on the screen. You should change the place or use dark, thick curtains or coat the glasses with anti-reflective material in order to reduce the glare.
- The blue light emitted from the computer causes a great amount of eye strain. You should adjust the brightness and keep it as low as possible.
Improve your home lighting:
For people who spend a lot of time at home working, adjustments should be made to the lighting in order to reduce eye strain.
- Avoid reading in a dim light room. This can give you headaches and produce eye strain. Any kind of activity where a lot of focus is required in dim or poorly lighted environments causes damage and strain to the eyes.
- Use desk lamps, reading lamps, under cabinet lights in the kitchen and other types of lights everywhere you work.
- If you work in a place for more than an hour, a nearby light would make it less stressful for the eyes.
For people with low vision:
- For people with less power of vision, proper lighting is a must. A 60-year old man would need to double the amount of light to carry out any activity which a man of 30 years would require.
- People having disorders such as macular degeneration, glaucoma and similar vision disorders need advanced lighting and should consult a doctor for ideas on improving their home lighting.
The presence of proper lighting improves our concentration, our ability to read, and we can differentiate between colors better. Therefore, always opt for the best lighting to avoid giving stress to your eyes. If you wish to discuss about any specific problem, you can consult an ophthalmologist.
I an facing problem of viewing objects which are far. This has started from last 2 weeks? I don't want to wear spectacle Is there any other way of curing my eyes?
I have been facing with sudden blurry eyes followed with minor head ache. This does not happen all the time or everyday. If I can recollect, have been having such difficulties may be 5 to 6 times in total from last 2 months. Consulted an eye specialist and I was told that my eye sight was all normal. Please advice and hope this isn't a major issue and requires medical attention. Thank you.
Macular Degeneration is an age-related macular degeneration incurable eye disease, which might result in blurred vision or no vision in the centre of the vision field, which might lead to visual distortions, reduced central vision, decreased intensity of the colours and can make it difficult for the patient to recognize faces, read, drive and to perform other activities.
Types of Macular Degeneration
1. Dry Macular Degeneration: It is characterized by the presence of drusen and thinning of macula because of a breakdown or thinning of the layer of retinal pigment epithelial cells in the macula.
2. Wet macular degeneration: In this type of AMD, there is an excessive growth of blood vessels, which causes bleeding, leakage, as well as scaring under the retina, which results in a rapid and severe loss of the central vision and might become permanent if not treated.
Causes of Age-related Macular Degeneration:
This is caused due to a problem related to the part of eye known as Macula, which is a spot at the centre of the retina of the eye. The focus point of the incoming ray of light is on Macula, which is responsible for see the things direct in front of us, especially reading and writing.
- Age: As the age increases, the probability of developing Age-related Macular Degeneration also increases significantly. The degree of the macular degeneration might vary person to person, but ageing is a major cause of suffering from age-related macular degeneration.
- Smoking: Smoking increases the chances of developing the disease in comparison to someone who does not smoke. The longer you have smoked, the more are the chances of developing it.
- Family History: The risk of developing the Age-related Macular Degeneration increases if it runs in your family, i.e. if your parents and siblings are suffering from it, then your chances of developing it are quite high as compared to the ones who do not have any family history.
- Obesity: The obese people have the higher chances of developing Age-related Macular Degeneration.
- Alcohol: Higher alcohol consumption also puts you at the risk of AMD, which is why one should always take alcohol in limited quantity only.
- Sunlight: As going out in sunlight without sunscreen is harmful to your skin, the same is harmful to your eyes for longer duration, and one should always wear UV-absorbing sunglasses to protect his eyes from AMD.
- Ethnicity: The white and Chinese are more prone to developing AMD as compared to the black people.
- Cardiovascular disease: The persons who have suffered diseases that affect the heart and other blood vessel are at higher risk of macular degeneration.
Treatment of Age-related Macular Degeneration
1. Anti-VEGF Drugs: The dry macular degeneration cannot be cured while the wet macular degeneration can be stabilized and maintained with a number of medical treatments to be injected into the eye, such as Lucentis, Avastin and Eylea. These are not long procedures and continued monitoring of the vision to maintain or improve the vision.
2. Laser photocoagulation: It consists of a concentrated beam of high energy thermal light that is directed towards the retina to obliterate and seal leaking blood vessels. If you wish to discuss about any specific problem, you can consult an ophthalmologist.
While spectacles are a fashion statement for some people, for others they are an uncomfortable necessity. Though contact lenses may be a little more aesthetically pleasing they too can be quite uncomfortable and cannot be worn throughout the day. Thankfully, there is a third way to correct vision. Laser surgery or LASIK, it is a popular refractive procedure that can correct common vision problems, such as nearsightedness, farsightedness and astigmatism. This procedure aims at reshaping the cornea so that light entering the eyes can be focused onto the retina for the person to have a clearer vision.
Laser surgery is pain-free and quick in most cases. Usually, it does not take more than 15 minutes to correct vision in both eyes. The results of this surgery can be seen in as little as 24 hours.
The first step of laser surgery to correct vision is to create a thin, circular flap in the cornea. This is then folded back to access the stroma or underlying cornea. An excimer laser is then used to remove some of the corneal tissue. For people suffering from nearsightedness, the cornea is flattened while for people suffering from farsightedness, the cornea is made steeper. In cases of astigmatism, an irregular cornea is smoothened. Once the correct gradient has been achieved the corneal flap is put back into place and the cornea is allowed to heal naturally. There are no stitches or bandages required in a laser eye surgery. You may feel a temporary burning or itching sensation in your eyes immediately after the procedure. It is important not to rub your eyes or place any pressure on them. Your vision may also be cloudy or blurred for the first few hours. A doctor will usually advise you to rest for a few days after the surgery so that your cornea can heal properly. In a few days, your eyesight should stabilize, though, in a few rare cases, it may take a little longer. You should also avoid any form of strenuous exercising for a few days after the surgery.
Though LASIK surgery has a very high success rate, there are very rare occasions where spectacles may still be needed even after the surgery. Thus LASIK is a choice of treatment for many who seek freedom from glasses. If you wish to discuss about any specific problem, you can consult an ophthalmologist.
One of the most cutting edge eye procedures which has been very successful in practice and has been loved by millions of patients is LASIK. LASIK is a form of eye surgery performed with the help of a precise laser and is very effective in correcting nearsightedness, farsightedness as well as astigmatism (imperfections with the shape of the cornea). With any such procedure, there are bound to be myths which arise out of misconceptions. Some of those myths as well as the advantages of LASIK have ben enumerated below:
Myth # 1 – Lasik can only be performed up to a certain age
Many people think that LASIK cannot be performed on people of advanced age. This is a misconception as LASIK has been performed on people above 90 as well. There are some considerations however, such as the health of the person and the condition of the eyes. If there are no medical objections, then LASIK can be performed regardless of the age of the person. Doctors also tend to wait till young adulthood (around 18-20 years of age) before performing LASIK. However, LASIK procedures have been performed on young children with severe vision problems as well.
Myth # 2 – The technology behind LASIK is too new and thus not yet perfected
This is yet another commonly propagated myth about LASIK. The technology for this procedure has been around for quite some time and has ben performed with increasing regularity since the 1980s. There have been multiple long term studies done on people who underwent LASIK surgery and almost all of them have had favorable results both in the short term as well as the long term. It is a properly established field and means of treatment within ophthalmology and is subject to the same stringent standards testing as other treatments within the field of medicine.
Myth # 3 – LASIK can cause many complications such as dry eyes and night glares
Any surgical procedure has a certain chance of complications occurring. However, LASIK tends to have very low occurrences of complications. What many people tend to confuse complications with is the normal healing procedure. Dry eyes and night glares usually occur after the first few weeks of the procedure and is part of the healing process of the body. It usually tends to go way with the first few months itself.
Myth # 4 – Contact lenses are better than LASIK
While contact lenses do serve a purpose in correcting vision, they can often contribute to eye infections as well as irritations and headaches. Also contact lenses need to be changed every few weeks or so. LASIK surgery eliminates all of these hassles and you can have perfectly clear vision without having to worry about all the problems that contact lenses bring with them.
Myth # 5 – The LASIK procedure is painful
No other myth is farther from the truth. In this procedure, the surgeon creates a thin flap like structure out of the tissue within the cornea with the help of a laser. This layer is then used to reshape the cornea and thus correct vision problems. Antiseptic and numbing eye drops are used when performing this surgery which results in minimal discomfort that only stays during the initial stages. If you wish to discuss about any specific problem, you can consult an ophthalmologist and ask a free question.
