ICD-11 code 1G01.0 refers to ocular myiasis, a rare condition caused by the invasion of fly larvae into the eye. Myiasis occurs when a fly lays eggs near or directly on a wound, which then hatch into larvae that feed on living or necrotic tissue. Ocular myiasis specifically involves the infestation of the eye or surrounding tissues by fly larvae.
Symptoms of ocular myiasis may include pain, redness, itching, and even visual disturbances. In severe cases, the larvae can cause damage to the eye, leading to vision impairment or loss. Diagnosis of ocular myiasis is typically made based on clinical symptoms and may be confirmed through the identification of larvae in the eye during an examination.
Treatment for ocular myiasis typically involves the removal of the larvae from the eye, either manually or through the use of medications to kill the larvae. In some cases, surgery may be necessary to prevent further damage to the eye. It is important to seek medical attention promptly if you suspect you have ocular myiasis to prevent complications and protect your vision.

#️⃣ Coding Considerations
The SNOMED CT code equivalent to the ICD-11 code 1G01.0, which represents Ocular myiasis, is 234412000. This code is used to specifically identify cases where larvae of flies infest the eye tissues or surrounding areas, leading to symptoms such as itching, redness, and even visual disturbances. By assigning a unique SNOMED CT code to Ocular myiasis, healthcare professionals can accurately record and track cases of this rare condition. This standardized coding system ensures that accurate and detailed information is consistently communicated among medical professionals and researchers. Utilizing SNOMED CT codes facilitates more efficient data analysis and research into rare diseases like Ocular myiasis, ultimately leading to improved diagnosis and treatment options for patients.
In the United States, ICD-11 is not yet in use. The U.S. is currently using ICD-10-CM (Clinical Modification), which has been adapted from the WHO’s ICD-10 to better suit the American healthcare system’s requirements for billing and clinical purposes. The Centers for Medicare and Medicaid Services (CMS) have not yet set a specific date for the transition to ICD-11.
The situation in Europe varies by country. Some European nations are considering the adoption of ICD-11 or are in various stages of planning and pilot studies. However, as with the U.S., full implementation may take several years due to similar requirements for system updates and training.
🔎 Symptoms
Ocular myiasis (1G01.0) presents with a range of symptoms that may vary depending on the severity of the infestation. Common signs of ocular myiasis include irritation, redness, tearing, and foreign body sensation in the affected eye. Patients may also report the presence of moving objects in their vision or a crawling sensation in the eye.
In more advanced cases, ocular myiasis may lead to swelling of the eyelid, discharge from the eye, and visual disturbances. Some individuals may experience pain, itching, and inflammation in the affected eye, which can worsen over time if left untreated. Severe cases of ocular myiasis can result in corneal damage, vision loss, and secondary bacterial infections.
It is important for individuals experiencing any of these symptoms to seek immediate medical attention from an ophthalmologist for proper diagnosis and treatment. Early detection and management of ocular myiasis are crucial in preventing complications and preserving vision. Prompt treatment typically involves removal of the larvae, administration of antibiotics, and supportive care to alleviate symptoms and promote healing.
🩺 Diagnosis
Diagnosis of ocular myiasis, coded as 1G01.0, typically involves a thorough clinical examination by an ophthalmologist. The presenting symptoms may include irritation, redness, foreign body sensation, and visual disturbances. The physician will evaluate the affected eye for any signs of infection or inflammation, as well as perform a detailed history to determine potential risk factors for myiasis, such as recent travel to endemic areas or exposure to contaminated environments.
Imaging studies, such as ocular ultrasound or computed tomography (CT) scan, may be performed to visualize any structural changes within the eye caused by the presence of larvae. In some cases, a slit-lamp examination may be used to identify the larvae directly within the eye. The identification of maggots in the eye confirms the diagnosis of ocular myiasis.
Laboratory tests, such as microscopy and culture of samples taken from the affected eye, may be conducted to identify the species of the larvae and determine the appropriate treatment. Additionally, blood tests for eosinophilia and serology for parasitic infections may be recommended to rule out other systemic conditions that may present with similar ocular symptoms. A multidisciplinary approach involving ophthalmologists, parasitologists, and infectious disease specialists may be necessary for the comprehensive diagnosis and management of ocular myiasis.
💊 Treatment & Recovery
Treatment for ocular myiasis typically involves removal of the larvae from the affected eye. This can be done through irrigation with saline solution or anesthetizing the eye to allow for manual removal. In cases where the larvae are deeply embedded, surgery may be necessary to extract them safely and effectively.
After the larvae have been removed, antibiotics or anti-parasitic medications may be prescribed to prevent infection and ensure complete eradication of any remaining larvae. These medications may be administered orally or via eye drops, depending on the severity of the infestation. Close monitoring by a healthcare professional is essential to track the progress of treatment and ensure the eye is healing properly.
Recovery from ocular myiasis depends on the extent of damage caused by the larvae and the effectiveness of treatment. In most cases, patients experience significant improvement in symptoms within a few days of treatment. However, follow-up appointments may be necessary to ensure the infestation has been fully resolved and no complications have arisen. It is important for patients to adhere to their prescribed treatment regimen and attend all follow-up appointments to promote a speedy recovery and prevent recurrence.
🌎 Prevalence & Risk
In the United States, the prevalence of 1G01.0 (Ocular myiasis) is relatively low compared to other regions. Due to sanitary living conditions and access to healthcare, cases of ocular myiasis are rare. However, occasional cases may still occur, particularly in rural or low-income areas where hygiene standards may be lower.
In Europe, the prevalence of ocular myiasis is also relatively low. Modern sanitation practices and healthcare systems help to prevent and treat cases of this condition effectively. Cases are sporadic and may be associated with travel to regions where myiasis is more common, such as tropical or subtropical areas.
In Asia, the prevalence of 1G01.0 (Ocular myiasis) may be higher compared to the United States and Europe. Factors such as warmer climates, poor sanitation, and living in close proximity to animals may increase the risk of myiasis in certain regions of Asia. However, the overall prevalence of ocular myiasis in Asia varies by country and specific geographic location within each country.
In Africa, the prevalence of ocular myiasis is relatively high compared to other regions. Factors such as poor sanitation, limited access to healthcare, and endemic regions of myiasis-causing insects contribute to the higher prevalence of this condition in certain parts of Africa. Efforts to improve hygiene practices and increase access to healthcare may help reduce the prevalence of ocular myiasis in these areas.
😷 Prevention
To prevent 1G01.0 (ocular myiasis), it is essential to take measures to avoid exposure to the primary causal factors of the disease. One of the primary factors contributing to ocular myiasis is poor hygiene and sanitation. Therefore, maintaining good personal hygiene, such as regularly washing hands and keeping living areas clean, can help reduce the risk of contracting this parasitic disease. Additionally, preventing contact with flies, which are vectors for the larvae responsible for ocular myiasis, can also be an effective preventive measure.
Furthermore, individuals living in regions with a high prevalence of ocular myiasis should take extra precautions to prevent the disease. This may include using insect repellents or wearing protective clothing to avoid fly bites. Additionally, keeping doors and windows screened can help prevent flies from entering living spaces and potentially transmitting the larvae responsible for ocular myiasis. Overall, taking these preventive measures can help reduce the risk of contracting this parasitic disease and protect individuals from the associated complications and discomfort.
