Eye Flashes - Know Why It Is Experienced!

Eye Flashes - Know Why It Is Experienced!

Eye flashes or photopsia can be caused by many conditions. Although flashes are harmless, they might indicate some serious eye issue which needs to be addressed immediately. Medical attention should be taken when flashes cause loss of vision and also small spots seem to float from one side to the other, thereby hindering the vision


Migraines and very severe recurrent form of headaches which last for few hours to many days can cause visual symptoms. The light flashes look like zigzag lines, geometric patterns and sparkles when they occur with a migraine. Flashes might affect one eye or both and occur in the peripheral area of the vision. Light flashes sometimes also occur due to an ophthalmic migraine, migraine without a headache.

Posterior Vitreous Detachment

The jelly-like substance or the vitreous fluid fill the center of the eye and also gives it shape, is attached to the retina. With age and over time there is shrinking of the vitreous and it begins to detach from the retina. This is known as posterior vitreous detachment. In this, the vitreous tugs or pulls on the retina, while the retina gets detached and stimulates it thus causing flashes to occur.

There is no known treatment for posterior vitreous detachment, through regular monitoring of the eye through eye checkups are helpful. Symptoms of this are similar to those of retinal detachment (condition in which there is permanent vision loss).

Retinal Detachment or Tear

Eye flashes and floaters may cause retinal detatchment. Retinal tear and detachment also cause light flashes in the eye. This needs to be treated promptly. In the case of permanent vision loss, there is a detachment of retina at the back of the eye, especially if the detachment takes place over the macula which is the main focus of the vision on the retina. When the retina detaches from the eye, it loses the main source of nutrients. As there are photosensitive cells in the retina which are responsible for vision, the results of the retinal tear are severe.

Retinal damage occurs after trauma or as a complication from diabetes or posterior vitreous detachment. Vitreous gel tends to seep under the retina from the small crevices and holes formed by the retinal thinning. This, in turn, raises the sections and disconnects it from the eye. This can be corrected by laser treatment, cryopexy or eye surgery.

Other Causes:

A trauma like a hard blow on the head can lead the person to experience flashes of light. Also, some medications can lead to toxic levels, like Digitalis can cause flashes of light. The symptoms of eye flashes also occur with macular degeneration, which is an age-related disease and in this, the vision reduces gradually.

Amblyopia or Lazy Eye - All You Should Know!

Amblyopia or Lazy Eye - All You Should Know!

Amblyopia is commonly known as 'Lazy Eye'. It is a vision development disorder, which affects eyes and the brain during infancy and childhood. It signifies that the eye does not achieve a normal visual acuity even with refractive correction in form of glasses or contact lens. During normal visual development, the eye and brain learns to 'see' and develop binocularity, that is the ability to perceive depth (Stereoacuity). This occurs in the first 3 to 8 years of life.

Each eye transmits a clear and identical image from retina to the brain, which fuses the two images into a single image with 3 dimensions ( adding depth). When the image is formed on the retina of two eyes is too dissimilar, the brain cannot fuse the two images and suppresses the more blurred image. As a result, the worse eye does not learn to 'see' and becomes 'lazy'. This condition is seen in 1-4% of population.

The common causes for dissimilar images or Amblyopia are:

1. Misalignment of the eyes or squint: It is the primary reason for Amblyopia is misalignment of the eyes. In case, both your eyes are not aimed in the same direction, the image captured by each eye is different , resulting in diplopia. The brain will see from the dominant eye and suppress image from the other eye. Over a prolonged period of time, the eye dissociates from the visual cortex of the brain.

2. Refractive Amblyopia:

  • Unequal refractive error in both eye. When the eye power of both eyes differ by more than 1.5D of spherical equivalent, which results in dissimilar images between the two eyes. As a result, the visual development in restricted in the worse eye.
  • High refractive error or astigmatism in both eyes, since there is a blurred image in both eyes, the normal vision development does not occur in either eyes resulting in bilateral lazy eyes.

3. Cloudiness in visual system or visual deprivation Amblyopia: Any kind of obstruction or cloudiness in the normal visual axis of the eye tissues can lead to Amblyopia. Disorder of any kind, which blocks a clear image from being focused blocks the formation of a clear image on your retina. Commonly due to congenital or developmental cataracts or corneal opacities or prolonged closure of one eye in early childhood( drooping of one eyelid, eyelid swelling, patching of one eye).

Treatment for Amblyopia: For treatment of Amblyopia, a child must be compelled to utilize his affected, weaker eye. This can be done by correction of causative factor such as, treating refractive error with glasses, surgical correction of misalignment of eyes followed by patching and vision therapy, cataract surgery.

Patching or occlusion of the good eye: This is done to force the brain to pay attention to visual input from the worse eye. This allows nerve connections between affected eye and brain to develop due to, which the eye 'learns to see'. Eye drops such as atropine are also used for blurring the vision of the good eye. Some form of vision therapy may also be required to train both eyes to see together and develop some degree of depth perception.

To be effective, treatment should be implement as early as possible , within the period of normal visual development best within first 8 years of life. Some visual gain has been seen in selected patients up to age of 14 to 18 years. This also highlights the importance of a comprehensive eye examination as a routine in young children.

Dry Eyes - What Causes It?

Dry Eyes - What Causes It?

Dry eyes are a common phenomenon that develops when the tears do not provide sufficient moisture to your eyes. This may also be the result of inadequate production of tears by the tear ducts. This condition cannot be cured permanently; however, treatments usually help.

Signs and symptoms of dry eyes:

1. A scratchy, burning and a stinging sensation in the eyes
2. Mucous surrounding the eyes
3. Sensitivity to light
4. Redness of the eyes
5. A feeling that something is stuck in the eyes
6. Problems in wearing contact lenses
7. Vision problems, especially while driving at night
8. Watery eyes caused due to the irritation that stems from dry eyes
9. Blurred vision

What are the causes?

1. Tears are a mix of fatty oils, water and mucus. This combination safeguards your eyes from any sort of infection in addition to keeping your ocular surface (the cornea surface) clear and smooth. Your eyes dry up if the tear ducts do not produce enough tears; medically, this condition is termed ‘keratoconjunctivitis sicca’. It can occur due to:

  • Age
  • Certain medical complications such as Sjogren’s Syndrome (a medical condition marked by dry eyes and a dry mouth) arthritis, diabetes, thyroid disorders and deficiency of Vitamin A among a few others
  • Side effects of certain medications such as anti-depressants, acne medications, birth control medications and medicines to control high blood pressure
  • Laser eye surgery or damage caused to the tear gland due to exposure to radiation or inflammation

2. Increased drying up or evaporation of the tears caused due to exposure to various kinds of smoke, dry air or wind, less of blinking while focusing on any particular activity or an object and eyelid problems such as in-turning of the eyelids (entropion) and out-turning of the eyelids (ectropion) can contribute to this irritating condition.

3. Imbalance in any of the layers constituting a tear film (made of oil, mucus and water) might lead to this condition.

4. Dry eyes can be the result of computer working or computer vision syndrome. Professionals working on computers should get tear measurement time to time to know it. This processs will ensure early detection and treatment if diagnosed positive. Hence, it will prevent loss of vision.

Preventive measures:

Avoid unnecessary using or staring on Computer, Laptop or Smartphones, which is now a very common practice. Don't allow kids to spend time watching smartphones. Now kids, adolescent are coming with dry eye, who are mostly watching, playing games on smartphone or computer.

Eye Examination - Why To Not Miss It?

Eye Examination - Why To Not Miss It?

Sight is one of our most important senses. To ensure that your vision is not compromised, regular eye examinations are essential. This is regardless of age and overall health because the only way to diagnose conditions in the eye in the early stages is with a comprehensive eye exam. By arresting them in the early stages, many eye disorders can be easily controlled and treated.

During a routine eye examination, the doctor will look into a number of aspects of your eye's health. An eye examination can also indicate serious health issues like diabetes, macular degeneration and glaucoma. Every person above the age of 40 should go for routine checkups to nullify the chances of issues like glaucoma, presbyopia, difficult near vision, etc. These checkups are really mandatory for people who feel sleepy after some work or have a headache while reading.

Some of the conditions an eye doctor looks for during an eye exam are:

Refractive error
If you already have a prescription this will be checked. In other cases, the strength of the eye muscles is checked for nearsightedness, farsightedness and astigmatism which can be corrected with Lasik surgery, spectacles or lenses. The earlier a refractive error is corrected, the lower are its chances of increasing. When it comes to children, they often do not realize signs of vision deterioration and hence, an eye examination becomes essential.

This is a condition where one eye has a much higher refractive error than the other or where the eyes are misaligned. If this is not treated in time, amblyopia can stunt vision in the affected eye and result in blindness.

Crossed or turned eyes are termed as cases of strabismus. This is caused by the misalignment of the eyes and can cause problems with depth perception. This can lead to amblyopia and eventual blindness if not treated in time.

Focusing and communicative problems between the eyes
An eye examination can also determine problems with focusing on objects. With children, this can be a sign of underdeveloped focusing skills while in adults it can be a symptom of presbyopia or age-related diminished focusing ability. Your doctor will also check how well your eyes work together. If they do not work in tandem, it can cause headaches, eye strains and problems with reading.

By looking at the blood vessels and retina of the eyes, doctors can detect signs of high blood pressure, cholesterol etc. Leaks in the blood vessels or bleeding in the eyes can also be a sign of diabetes or swelling of the macula.

Age-related conditions
As with the rest of the body, the eye tissues and muscles also degenerate with time. Cataract is one of the most common age-related issues that affect the eyes.

Color vision problem: 
Detecting this problem is very necesssary, esspecially in case of children. Every student must go for regular eye checkups to avoid such problems and eventually opt for the desired professsional career.
