Age-Related Macular Disease, or AMD, is an acquired ocular disorder that occurs in people over sixty years of age. It is the leading cause of vision loss in the US. This eye disease affects the central part of the retina, known as the macula, and destroys it through retinal detachment. The macula is responsible for providing a sharp and clear central vision that is required for reading, writing, and other visually demanding activities such as driving, stitching, etc. The risk of AMD increases with age.

Our eyes are integral to our body, allowing us to view the world around us. Imagine being able to touch, smell, hear, and feel everything but not see, like a car with dead headlights driving down a highway. The dark isolation of vision loss can be quite horrifying!
This fantastic process happens when the optic nerve creates an image through the cornea and displays it on the retina (a light-sensitive layer of tissue that acts like a screen). Retinal detachment, or RD, is a medical condition where the retina peels off from the surrounding tissue.
Color vision deficiency, or color blindness, is the inability to distinguish certain shades of colors. In highly severe cases, people can’t see the concerned colors at all, though very few people are completely color blind (who can see things only as black, white, and shades of gray).
Color blindness occurs when there is damage or loss of cones, which are the photoreceptors in the retina, making color vision possible. If the cones lack one or more light-sensitive pigments, the color perception will be deficient, making it difficult to see one or more of the three primary colors.
Cataracts occur when there is a clouding of the clear lens, located directly behind the iris leading to clouded and misty vision. This mostly occurs in older people, but it may develop in infants and kids too. Some people can even be born with a cataract.
Let’s understand more about childhood cataracts.

There are a number of people suffering from glaucoma. Unfortunately there is no cure for this eye disease, but the good news is that it can be controlled through medication. The glaucoma treatment primarily focuses on lowering the IOP (intraocular pressure) to a level that doesn’t cause optic nerve damage. Elevated IOP damages the optic nerve significantly, which is why containing the pressure is critical. The pressure to be achieved is known as the ‘target pressure’ or ‘goal pressure.’ This varies from one person to the other, and it may change during the course of treatment.
The ophthalmologist will study your glaucoma symptoms and prescribe the medication accordingly to lower the pressure on your eye. In the recent years, there has been an increase in the choices for topical treatment of glaucoma – prostaglandin analogs and prostamides being two of them. A prostaglandin analog medication is a preferred choice of many doctors for treating any kind of glaucoma, including congenital glaucoma.
These medicines increase the outflow of aqueous humor, thus lowering the intraocular pressure. Aqueous humor is a fluid that the eye continually makes and is crucial for proper functioning of eye. These medications should be taken once a day.
These medications comprises of:
Though most medications, including eye-drops, are safe to use – some may have side-effects. People may experience the following symptoms as side-effects:
It is advised that people with a history of eye problems such as uveitis, history of retinal swelling or ocular herpes infection use these medications with caution. If you suffer or have suffered from any kind of eye ailments, discuss with your doctor before proceeding with any kind of treatment for glaucoma treatment. It is important that you take your glaucoma medications regularly as prescribed for them to show the desired results.
Before you start taking any medication that your ophthalmologist prescribes, you should understand certain things.
How will these medications react with the medication of a different treatment you might be on. It is of utmost importance that your doctors know about the different medications that are prescribed to you. Include the non-prescription medications as well. This will help them in planning the appropriate treatment plan for you, without any risk of threatening medical problems or side effects.
If you or a loved one is suffering from glaucoma, then it is advisable to visit a doctor immediately to control the condition before it worsens any further. Even if you don’t have glaucoma right now but your family has a history of this ailment, you should get regular check-ups to detect it in the early stages. Once you are on medications, you have to be disciplined about taking them without fail. Request an appointment with InSight Vision Center and get a consultation today.
When the shape of the eye prevents the light rays from focusing directly on the retina and rather focuses on the front or back of the retina, refractive error occurs. Factors such as the length of the eyeball, aging of the lens, and change in the shape of the cornea contribute to refractive errors.
