What is Eye Palsy? Ophthalmoplegia, also known as eye palsy is the weakness or paralysis of the eye muscles. It affects the movement of an eye and the six muscles that hold the eye in the place.       Patient affected by  Eye Palsy Photo Credit: Health Jade There are 2 types of Ophthalmoplegia:  Chronic progressive external ophthalmoplegia  Internuclear ophthalmoplegia   Chronic progressive external ophthalmoplegia Chronic progressive external ophthalmoplegia typically begins with drooping eyelids and difficulty controlling the muscles that help in eye coordination. It typically appears in adults between the ages of 18 to 40 years. Internuclear Ophthalmoplegia  Photo Credit: Internal Medicine Made Easy Internuclear ophthalmoplegia leads to double or blurred vision. It is caused by nerve damage to the nerve fibers that coordinate lateral eye movement.   What causes eye paralysis? Ophthalmoplegia can be congenital (by...

Pink eye Pink eye is also known as conjunctivitis, is an infectious and common eye condition that affects about 2 million people annually. If you or your child have pinkish-red, itchy, and crusty eyes, call an optometrist or make an appointment immediately. Pink Eye Photo Credit: Medical News Today Pink eye occurs when a thin membrane of tissue called the conjunctiva is infected. This is what causes the small blood vessels in the conjunctiva to be more visible. When these small blood vessels are inflamed, the whites of your eyes appear reddish or pink.   What Causes Pink Eye?   Diagramatic representation of Pink eye (Conjunctivitis) Photo Credit: Eye doctors in NYC Pink eye is extremely contagious caused by a viral or bacterial infection. If you develop symptoms from an upper respiratory infection like sneezing, coughing, or a sore throat, it can be due to viral conjunctivitis. Environmental irritants like cosmetics, smog, and chlorine can also cause inflammation...

Dryness in the eye, burning sensation leads to a mild decrease in vision and sometimes excessive tearing which is often excaberated by smoke, wind, heat, low humidity or prolonged use of mobile phones or computers is something you face?  And is it causing an immense problem to your day-to-day lifestyle? You might be having something called as a Dry eye syndrome. The above-mentioned problems are the most common symptoms of dry eye syndrome. So what is a Dry eye syndrome?  There lies a  tear film superficial to our cornea this tear film comprises three different layers namely a  lipid layer on the top, an aqueous layer in the middle, and a mucus layer in the bottom just above the cornea.  The  lipid layer prevents quick evaporation of the tear and it is secreted by the Meibomian glands  The  aqueous layer  contains electrolytes for the nourishment of the cornea and is secreted by the lacrimal glands, Glands of Krause  and Wolfring  T...

  What is Keratoconus? Keratoconus often referred to as KC, is a genetic eye condition in which the cornea thins with time and weakens, causing the development of a cone-like bulge and optical irregularity of the cornea.  Normal eye Vs Keratoconus Photo Credit : R esearch gate The middle part of the cornea, made up of protein and water is known as collagen.  Collagen is round in shape and helps to keep the cornea strong and flexible. It focuses on light to help us see clearly.  What Causes Keratoconus? Blurred vision while driving Photo Credit: Shutter stock According to a report by Hopkins medicine "Keratoconus" occurs in approximately one in 2000 individuals, typically beginning in puberty and progressing into the mid-30s.  It is believed that the predisposition to develop Keratoconus is present at birth.  Common research in Keratoconus is the loss of collagen in the cornea.   This can be caused by some imbalance between production and destruction of...

  The eyepatch that pirates used to wear, was that a fashion statement or was it to make up for a missing eye? In movies and storybooks  we are always forced to visualize pirates  wearing  eyepatches But why did they  wear them let us  learn A  human eye takes several minutes to become used to dark surroundings we call it dark adaptation and it takes more time to get used to dark if you are coming from a bright light condition(The complexities of The Pupil and the photoreceptors in the retina are responsible for this).  It is estimated that intelligent pirates soon observed this and patched  their  other  eye so that when they are on the surface  of the ship ie.,  bright light conditions and suppose there is an attack by an enemy  pirate and they have to quickly retreat to the deck ie., Dark environment,  they immediately shift the patch  to another eye thereby reducing the time of dark adaptation significa...

LASIK eye surgery is the best known and most commonly performed laser refractive surgery to correct vision problems. Laser-assisted in situ keratomileusis (LASIK) can be an alternative to glasses or contact lenses. During LASIK surgery, a special type of cutting laser is used to precisely change the shape of the dome-shaped clear tissue at the front of your eye (cornea) to improve vision. In eyes with normal vision, the cornea bends (refracts) light precisely onto the retina at the back of the eye. But with nearsightedness (myopia), farsightedness (hyperopia) or astigmatism, the light is bent incorrectly, resulting in blurred vision. Glasses or contact lenses can correct vision, but reshaping the cornea itself also will provide the necessary refraction. Why is it done? As the most commonly performed eye surgery to treat myopia (nearsightedness), hyperopia (farsightedness), and astigmatism, thousands of people have LASIK each year. And yet, many people sti...

Childrens are different from adults as they have a different ocular surface a different configuration and slightly different physiology which is needed to be analyzed during contact lens fitting. The second most parameter is that children do not allow/ cooperate well with the practitioner unlike the adults so contact lenses trials to assess the best fit cannot be conducted this makes fitting contact lenses in children a bit difficult. But this fact does not stop optometrists from fitting contact lenses in children Here are some instances when your optometrist  would prescribe contact lenses in children below the age of 5 years: High myopia (high minus power)   Moderate to high hyperopia ( high plus power)   Moderate to high anisometropia ( a large difference between the refractive powers of the two eyes)   Amblyopia ( unilateral for bilateral vision loss since childhood due to stimulus deprivation or various other causes)   Nystagmus ( Rhythmic  oscillatio...
