As an eye clinic with Ophthalmologists we care many eye-conditions professionally and with extreme care
Keratoconus is the
gradual thinning and outward bulging of the cornea into a cone shape. This progressive
eye condition usually affects both eyes by thinning the corneas from that of a normal
rounded dome-shape into one that has a cone-shaped bulge. The cornea is the clear,
central part of the surface of the eye. In those patients with keratoconus, the
cone-shaped cornea deflects light and causes distorted vision.
Causes Of Keratoconus :
Genetics, A collagen deficiency, Overexposure to ultraviolet rays from the sun, Excessive eye-rubbing, Allergies, An injury to the eye, Diseases of the eye
Symptoms Of Keratoconus :
Keratoconus often begins to develop in the teen years to the early 20s, although it can develop at any age. Changes in the shape of the cornea occur gradually, usually over several years. In most patients with keratoconus, both eyes eventually become affected.
Keratoconus can be difficult to detect because it usually develops very slowly. Signs and symptoms of keratoconus may include:
Distorted and blurry vision, Increased nearsightedness, or myopia, Astigmatism, Double vision, Halos around bright lights, Frequent changes in eyeglass prescription, Inability to wear contact lenses, Headaches due to eye strain, Glare, Light sensitivity
Treatment For Keratoconus
In the early stages of keratoconus, glasses or soft contact lenses may help to correct the nearsightedness and associated astigmatism. As the condition progresses and the cornea becomes thinner, more advanced treatment is required.
also known as age-related macular degeneration (AMD) is a common condition in older
adults and the leading cause of vision loss and blindness in people over the age of 65.
Macular degeneration affects the macula, the part of the retina responsible for the
crisp, detailed vision needed for reading or driving. As we age, the tissue in the eye
responsible for central vision slowly begins to deteriorate which can significantly
affect a patient’s quality of life.
Patients with macular degeneration may notice gradual changes to their vision, including shadowy areas in the central vision, or fuzzy and distorted vision. These areas grow larger as the disease progresses, and can eventually turn into blind spots. Patients may also have difficulty seeing color and fine details.
If the disease progresses to the wet form, patients may also see straight lines as wavy. With wet macular degeneration, central vision loss can occur rapidly, sometimes in as little as a few days or weeks.
Causes And Risk Factors
Many cases of macular degeneration are a result of aging and the natural deterioration of the eye tissue that is needed for clear vision. This disease can also be related to a genetic factor in patients who have a gene variant known as complement factor H. Nearly half of the blinding cases of macular degeneration are linked to this genetic deficiency.
While there is no cure for macular degeneration, there are several treatment options available to help patients manage this condition and preserve their vision. The best treatment option for each patient depends on the severity and type of the condition, as well as how much, if any, permanent vision loss has occurred.
The macula is a small
spot in the center of the retina that focuses light at a sharp point and allows us to
see objects in detail. This is especially useful for reading, driving and other everyday
activities that require clear vision. A macular hole often develops as part of the
natural aging process, when the vitreous gel thins and separates from the macula. This
can pull on the macula and cause a hole to form. Macular holes can also develop from
injury, inflammation, retinal detachment or other eye diseases.
In its early stages, a macular hole may cause a small blurry or distorted area in the center of vision. As the hole grows over time, central vision progressively worsens, and peripheral vision may also be affected. There are three different stages of macular holes, including foveal detachments, partial-thickness holes and full-thickness holes. Each stage can progress to the next if left untreated.
Most macular holes can be successfully treated through vitrectomy, a surgical procedure to remove the vitreous gel and stop it from pulling on the retina. The doctor then inserts a mixture of air and gas into the area to keep its shape. Vitrectomy is performed on an outpatient basis under local anesthesia and is considered a safe and effective treatment for a macular hole.
