The term "punctum pustulatum" originates from the "Compendium of Diseases Sources and Syndromes - Specific Syndromes of Eye Diseases - Pustular Cataract Syndrome."
Also known as theft of the needle, soil eruption, or soil ulcer.
Equivalent to the condition referred to in Western medicine as a staphylococcal abscess.
Pin prick is a common eye disease in daily life, which has not much harm to people but also has less impact.
What is a "sore"? The term "sore" originates from the "Compendium of Diseases Originating from the Eyes and Ears," specifically in the section "Diseases Related to the Eyes."
Also known as "stealing the needle," "earth boil," or "earth ulcer."
Equivalent to what is referred to in Western medicine as a stye.
It primarily manifests as a condition characterized by redness, swelling, and heat with pain at the margin or internally of the eyelid, presenting as small sores resembling millet kernels.
A pustule is a type of acute purulent inflammation located near the sebaceous gland or meibomian gland in the eyelash follicle.
There are two types of glands in the eyelid: one at the base of the eyelashes, called the sebaceous gland, which opens into the hair follicle.
Another type of gland embedded near the surface of the conjunctive membrane and buried in the eyelid is the meibomian gland, which opens at the margin of the eyelid. Acne is an acute pyogenic inflammation caused by these two types of glands. The bacteria that cause acne are mostly Staphylococcus aureus, so acne is typically pyogenic inflammation.
For minor cases, applying heat to the acupoint can promote pus formation. If the condition is mild, improvement can often be seen after applying heat. Additionally, Chloramphenicol eye drops can be used for treatment. For cases with excessive secretions, Liforin eye drops can be employed.
If the abscess persists for a long time, it is advisable to visit a hospital for incision and drainage.
Do not squeeze your nose with your hand. Otherwise, you will have many complications.
Pinhole symptoms: Pinhole is a very common ophthalmic disease in our daily life, which has no great danger to people but also has a certain impact.
Now, let's delve into the symptoms of a pin prick. A pin prick refers to staphylococcal ophthalmic inflammation, also known as acute punctate dermatitis.
For those located in the follicular area, it is termed an external staphylococcal pustule; for those involving the conjunctival sac, it is called an internal staphylococcal pustule.
Chinese medicine refers to it as "Tu Dan," colloquially known as "Needle Eye" or "Beaded Pearl."
The main symptoms are as follows: initially, slight itching and pain in the eyelid area; followed by slight redness and swelling near the lateral canthus of the eyelid, which subsequently develops into a localized firm nodule with tenderness, and the nodule is connected to the skin.
If the lesion is located at the inner corner of the eye, it will cause severe redness and pain, and may lead to the white part of the eyeball becoming swollen.
Some patients may also present with cervical or submandibular lymphadenopathy and tenderness, even accompanied by chills, fever, headache, and other systemic symptoms.
In mild cases, it may spontaneously resolve within several days; in severe cases, a yellowish-white pus-like nodule will appear at the lash line near the eyelashes within 3 to 5 days.
When the abscess ruptures, the pain decreases and the swelling subsides.
If it is located on the inner surface of the eyelid, there is a more severe redness and pain. There is often localized congestion in the eyelid, and yellowish pus points can be seen protruding, which may spontaneously rupture.
The etiology of pin prick is a localized, acute suppurative inflammation of the sebaceous or tarsal glands near the eyelash follicle.
This is a common eye condition among children.
Healthy human eyelids have the ability to defend against external pathogens. However, young children, being unaware and often crying, frequently rub their eyes with dirty hands, allowing bacteria to take advantage and invade.
The bacteria that cause styes are mostly Staphylococcus aureus, so styes are mostly suppurative inflammations.
In this section, we will provide a detailed introduction to the causes of styes: 1. Bacterial infection.
The meibomian glands are located deep within the eyelids but open at the eyelid margin. Bacteria, primarily staphylococci, can enter the sebaceous glands at the base of the eyelashes or the meibomian glands deep within the eyelids through these openings, leading to acute suppurative inflammation and the formation of a stye.
2. Decreased immunity.
The eyelids of a healthy person possess a strong defensive capability, enabling them to resist the invasion of external bacteria. However, when the body's resistance weakens (due to factors such as malnutrition, lack of sleep, or conditions like diabetes), it becomes more susceptible to illness.
3. Eye Diseases.
When suffering from blepharitis, trachoma, chronic conjunctivitis, or eye strain due to excessive use of the eyes, as well as having conditions such as myopia, hyperopia, or astigmatism, failure to promptly correct vision with glasses can also lead to the development of a stye (hordeolum).
4. Eye hygiene.
Neglecting eye hygiene, such as using unclean towels or handkerchiefs to wipe the eyes, can allow bacteria to invade the glands of the eyelids, potentially leading directly to the occurrence of a stye.
Can styes be contagious? A stye, medically known as a hordeolum, is an acute suppurative inflammation of the eyelid's sebaceous glands, often caused by a staphylococcal infection.
In healthy eyelids, the secretion and excretion of the glands are normal, making it difficult for bacteria to proliferate and cause inflammation within the glands.
However, if the gland's secretion is not smooth or if it comes into contact with unclean substances and becomes infected with bacteria, causing inflammation, a stye may develop.
The following situations are more likely to cause styes: excessive fatigue, emotional stress, leading to endocrine disorders, and poor excretion of sebaceous glands.
Oily skin type, with overactive sebaceous glands, prone to clogged pores.
Rubbing your eyes with unclean hands can easily lead to bacterial infection.
Since a stye is an acute inflammation, it presents with inflammatory symptoms such as redness, swelling, heat, and pain.
Generally speaking, a minor stye will heal within three to five days.
The treatment involves the topical application of antibiotic ointment, and warm compresses can help accelerate the fading of the stye.
If pus spots appear, they should be incised and drained.
If the infection symptoms are severe, oral antibiotics are required.
From this, it can be seen that a stye is not contagious.
How to Prevent Styes A stye is an acute purulent inflammation caused by bacterial infection of the eyelid gland tissue, with the most common causative bacterium being Staphylococcus aureus.
Styes develop rapidly and are characterized by localized redness, swelling, and pain at the base of the eyelashes. In the early stages, a hard nodule with tenderness may form. After a few days, the nodule softens, and a yellowish-white pus head becomes visible at the base of the eyelashes. The pus may spontaneously rupture and drain, leading to a rapid reduction in redness and swelling.
Patients with severe conditions may exhibit systemic fever and enlargement of the lymph nodes in the anterior part of the ear.
How should a pinprick be prevented? First, pay attention to eye hygiene, keep the eyes clean, and don't rub or touch your eyes with dirty hands or objects.
Secondly, make sure to rest adequately. It is advisable not to watch TV, use a computer, or do homework for too long, as this can lead to excessive fatigue and deprive your body of the necessary rest.
Simultaneously, actively treat the chronic inflammation of the eye. For recurrent cases of styes, it is important to check for refractive errors and if present, correct them promptly.
Finally, if you have blepharitis, conjunctivitis, or trachoma, it is important to seek timely treatment.
Patients with diabetes, multiple furuncles, pulmonary tuberculosis, tonsillitis, and other chronic diseases also need timely treatment.
