Wet Age-Related Macular Degeneration (ARMD)


Introduction 

Age-related macular degeneration (ARMD) is a leading cause of vision loss among older adults. The condition is characterized by the gradual deterioration of the macula, a small area of the retina responsible for central vision. There are two main types of ARMD: dry and wet. Wet ARMD, also known as exudative ARMD, is less common but more severe than dry ARMD, and is caused by the growth of abnormal blood vessels under the retina, which can leak fluid and blood and cause damage to the macula.

Symptoms 

Wet ARMD typically progresses more rapidly than dry ARMD and can cause significant vision loss in a short period of time. Symptoms of wet ARMD include sudden loss of central vision, distorted vision, difficulty reading, recognizing faces, or performing other tasks that require fine vision, and a rapid progression of blind spots in central vision.

Risk Factors 

The most significant risk factor for developing wet ARMD is age. Other risk factors include a family history of the condition, smoking, high blood pressure, and exposure to UV light. Individuals with dry ARMD are also at an increased risk of developing wet ARMD.

Diagnosis 

A comprehensive eye exam is typically used to diagnose wet ARMD. This exam may include tests such as a visual acuity test, a dilated eye exam, and a fluorescein angiography.

Treatment 

While there is currently no cure for wet ARMD, there are several treatment options available to slow the progression of the condition and preserve vision. These include:

  • Anti-VEGF therapy: This involves injecting a medication into the eye that blocks the growth of abnormal blood vessels.
  • Photodynamic therapy: This involves injecting a light-sensitive dye into the bloodstream, followed by shining a special light into the eye to destroy abnormal blood vessels.
  • Laser therapy: This involves using a laser to destroy abnormal blood vessels and reduce the risk of bleeding.

Prognosis 

The prognosis for wet ARMD varies depending on the severity of the condition, the individual's age and overall health, and the effectiveness of treatment. With early detection and prompt treatment, many individuals with wet ARMD are able to preserve their vision. However, in some cases, the condition may progress rapidly and cause severe vision loss.

Conclusion 

Wet age-related macular degeneration (ARMD) is a severe form of the condition that can cause significant vision loss in a short period of time. While there is currently no cure, there are several treatment options available to slow the progression of the condition and preserve vision. Individuals at risk for wet ARMD should have regular eye exams and take steps to reduce their risk factors. Early detection and prompt treatment are key to preserving vision in individuals with wet ARMD.

Mosquito eyes

 Mosquitoes, like many other insects, have compound eyes. Compound eyes are made up of numerous individual photoreceptor units called ommatidia. Each ommatidium consists of a lens, a cornea, a crystalline cone, and a light-sensitive receptor cell.  Mosquito compound eyes are typically large in proportion to their body size and are positioned on the sides of their head. They have a spherical shape and provide mosquitoes with a wide field of vision, allowing them to detect movement in different directions.  The compound eyes of mosquitoes are designed primarily for detecting changes in light intensity and movement rather than forming detailed images. Each ommatidium captures a small part of the overall image, and the mosquito's brain processes the input from multiple ommatidia to form a composite picture of its surroundings. Mosquitoes are attracted to certain stimuli such as heat, carbon dioxide, and chemicals in human sweat, which help them locate potential hosts for blood meals. T

Contact lens parameters

 Contact lenses are medical devices that are worn directly on the cornea of the eye to correct vision or for cosmetic purposes. There are various parameters associated with contact lenses that are important for fitting and prescribing the right lenses for individuals. Here are some common parameters: 1. Power (Refraction): Contact lenses are available in different powers to correct nearsightedness (myopia), farsightedness (hyperopia), astigmatism, and presbyopia. The power is measured in diopters (D) and can be positive (+) or negative (-) depending on the type of vision correction needed. 2. Base Curve (BC): The base curve determines the curvature of the contact lens. It is typically measured in millimeters (mm) and represents the curvature of the inner surface of the lens. The base curve is chosen to match the curvature of the cornea for proper fit and comfort. 3. Diameter (DIA): The diameter of a contact lens is the measurement across the lens from edge to edge. It is usually measur

Base Curve of contact Lens

The base curve of a contact lens refers to the curvature of the back surface of the lens. It is measured in millimeters and is one of the main characteristics of a contact lens. The base curve is important because it determines how well the lens will fit on the eye. A lens with a base curve that is too flat may not conform to the shape of the eye and may cause discomfort or irritation. On the other hand, a lens with a base curve that is too steep may be difficult to insert and remove and may cause lens dislocation or other problems. To find the right base curve for a contact lens, an optometrist will measure the curvature of the eye using a tool called a keratometer. This instrument measures the curvature of the front surface of the eye (the cornea) and helps the optometrist determine the appropriate base curve for the lens. In addition to the base curve, other factors that can affect the fit and comfort of a contact lens include the diameter of the lens and the material o
