INVESTIGATIONS of FUNDUS BY LASERS

 Laser treatment is a common method used for the diagnosis and management of various eye conditions that affect the retina, the light-sensitive layer of tissue at the back of the eye. There are several different types of laser treatments that can be used to investigate the fundus, or the interior surface of the eye, including laser photocoagulation, laser photodynamic therapy, and laser therapy for age-related macular degeneration.

Laser photocoagulation is a widely used treatment for diabetic retinopathy, a condition in which high blood sugar levels damage the blood vessels in the retina. The procedure uses a laser to seal off leaking blood vessels and to reduce the risk of bleeding. The laser burns small spots on the retina, which causes the abnormal blood vessels to shrink and stop leaking. This treatment can prevent the progression of diabetic retinopathy and reduce the risk of vision loss.

Laser photodynamic therapy is a treatment that uses a laser in combination with a photosensitizing drug to treat neovascular age-related macular degeneration (AMD), a condition that causes the formation of new blood vessels in the retina that can lead to vision loss. The drug is injected into the bloodstream and is absorbed by the abnormal blood vessels. The laser is then used to activate the drug, which causes the blood vessels to shrink and stop leaking.

Another laser treatment that is used for age-related macular degeneration is called laser therapy. The procedure uses a laser to create a small burn on the retina, which can help to stop the growth of new blood vessels and reduce the risk of vision loss.

It's important to note that laser treatment is not a substitute for a comprehensive eye exam. An eye exam should be done regularly to detect and treat any eye problem as soon as possible. Additionally, it's important to have a clear understanding of the risks and benefits of laser treatment from a medical professional before undergoing the procedure.

In conclusion, Laser treatment is a common method used for the diagnosis and management of various eye conditions that affect the retina. There are several different types of laser treatments that can be used to investigate the fundus, including laser photocoagulation, laser photodynamic therapy, and laser therapy for age-related macular degeneration. These treatments can prevent the progression of diabetic retinopathy and reduce the risk of vision loss in some cases. However, it is important to have a clear understanding of the risks and benefits of laser treatment from a medical professional before undergoing the procedure, in conjunction with regular comprehensive eye exams to detect and treat eye problems as soon as possible.

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
