12. Inflammatory eye diseases

Signs of diseases of the eyelids are very characteristic. Patients are often concerned about itching and burning in the eyelids, eye fatigue, and there may be a change in the shape and size of the palpebral fissure, the position of the ciliary edge of the eyelids, etc. The pathology of the eyelids, unlike diseases of the eyeball, is quite easy to determine already with an external examination. Since the symptoms of inflammation of the soft tissues of the eye and the optical structures themselves are not long in coming.

A sharp swelling and hyperemia of the eyelids may indicate the presence of gonoblenorrhea (in children), diphtheria, as well as an abscess of the eyelids, acute meibomitis, barley. Edema, especially in the outer part of the upper eyelid, is noted in cases of inflammation of the lacrimal gland. Pronounced "cold" edema can be with allergic conditions.

When examining the edge of the eyelids, attention is paid to the features of eyelash growth, the presence of skin changes at their base, the condition of the excretory ducts of the meibomian glands. To clarify the diagnosis, carefully examine the eyelids and their position under side lighting and palpation. During the examination, attention is paid to the presence of skin lesions, which can be the entrance gate for infection.

1. Abscess of the century (abscessus palpebrae). On examination, hyperemia of the skin of the eyelids is determined, palpation reveals induration (edema, infiltration) and tissue tension, their soreness.

In addition, the pre-auricular lymph nodes may be enlarged and painful. If, along with all these signs, there is local softening and fluctuation, then opening the abscess (incision) is advisable. In the absence of fluctuations, the administration of antibiotics in the form of injections around the abscess and oral administration of antibiotics or sulfonamides and UHF therapy are indicated.

2. Meibomite (meibomitis, hordeolum internum).

If, when examining a patient, there is limited infiltration in the eyelid area, the eyelid is painful on palpation, and when everted through the conjunctiva, a translucent yellowish focus in the cartilage is visible, then the diagnosis of meibomitis is undoubted acute purulent inflammation of the meibomian gland. Severely leaking meibomitis can lead to the formation of an extensive abscess of the eyelid.

Treatment. Warming procedures, UHF therapy, disinfectants.

3. Chalazion is a tumor-like, limited, somewhat protruding formation, dense to the touch, painful, soldered to cartilage. It usually occurs after acute inflammation of the eyelid (meibomitis) and in some cases gradually increases.

Treatment of chalazion (hailstones) consists in absorbable drug therapy. However, most often it is ineffective, and then surgical removal of the hailstone in the capsule through an incision in the conjunctiva of the eyelid and cartilage is indicated, followed by treatment of the chalazion bed with an iodine solution.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

Helicopter with muscle drive 12.11.2011

Students at the University of Maryland (USA) built a muscle helicopter, hoping to win the Sikorsky Prize. It is 250 thousand dollars, proposed in 1980 and will be issued to someone who, due to muscle strength, will come off the ground by a helicopter three meters (counting from the lowest part of the structure) and hang at this height within a square with a side of 10 meters at least 60 seconds.

So far, the highest achievement of the device is lifting a few centimeters in the gym and hanging in the air for 12,4 seconds. The helicopter has four screws, is built from the lightest materials and weighs 95,25 kilograms together with the pilot.

The pilot - student Judy Wexler, an experienced cyclist, worked with her hands and feet, developing a power of about one horsepower.
