ICD-11 code 1F6A.0 refers to onchocerciasis of the eye, a parasitic infection caused by the nematode Onchocerca volvulus. This disease is commonly known as river blindness due to its association with areas where the black fly vector breeds near fast-flowing rivers. Onchocerciasis primarily affects the eyes, leading to inflammation, itching, and ultimately vision loss if left untreated.
The symptoms of onchocerciasis of the eye include severe itching, redness, and sensitivity to light. The parasite causes damage to the optic nerve and can lead to visual impairment or blindness if not treated promptly. Onchocerciasis is a major cause of preventable blindness in endemic regions, particularly in sub-Saharan Africa.
Treatment for onchocerciasis of the eye typically involves the use of antiparasitic medications, such as ivermectin, to kill the adult worms. In some cases, surgical intervention may be necessary to remove the nodules formed by the parasite underneath the skin. Public health programs focused on controlling the black fly population and interrupting transmission of the parasite have been successful in reducing the burden of onchocerciasis in affected communities.

#️⃣ Coding Considerations
The SNOMED CT code equivalent to the ICD-11 code 1F6A.0 for Onchocerciasis of the eye is 239448005. This code specifically identifies cases of Onchocerciasis affecting the eye region within the standardized SNOMED CT system. SNOMED CT is a comprehensive clinical terminology that provides a standardized way to represent and capture patient information within electronic health records, allowing for better interoperability and communication between healthcare providers. By using SNOMED CT codes, healthcare professionals can accurately document the diagnosis and treatment of Onchocerciasis of the eye in a standardized manner that is easily understood across different healthcare settings. This helps to improve the quality of care for patients with this condition by ensuring consistent and accurate data capture and sharing.
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
Symptoms of 1F6A.0, or Onchocerciasis of the eye, typically manifest in the form of itching and irritation of the eyes. Affected individuals may experience redness and inflammation of the conjunctiva, along with tearing and sensitivity to light. These symptoms may progress to the formation of nodules on the eyelids and the development of pterygium, a growth of tissue on the cornea.
In more severe cases of Onchocerciasis of the eye, individuals may suffer from visual impairment and even blindness. This can occur due to damage to the optic nerve caused by the presence of the Onchocerca volvulus worm in the eye tissues. Visual acuity may be diminished, and individuals may experience blurry vision, difficulty focusing, and other visual disturbances.
In addition to eye-related symptoms, Onchocerciasis can also lead to skin manifestations, such as severe itching, rashes, and skin discoloration. These cutaneous symptoms are the result of the presence of microfilariae in the skin, which can cause inflammatory reactions and immune responses. The combination of eye and skin symptoms can significantly impact the quality of life of individuals affected by Onchocerciasis of the eye.
🩺 Diagnosis
Diagnosis of 1F6A.0, also known as Onchocerciasis of the eye, typically involves a combination of clinical evaluation, imaging studies, and laboratory tests.
One of the primary methods used in diagnosing Onchocerciasis of the eye is through a detailed clinical examination by a healthcare provider. This may involve assessing the visual acuity, examining the eyes for signs of inflammation or damage, and looking for the presence of characteristic lesions caused by the parasitic worm Onchocerca volvulus.
Imaging studies, such as ultrasound or optical coherence tomography (OCT), may also be used to visualize the structures of the eye affected by Onchocerciasis. These imaging techniques can help identify any abnormal changes in the eye caused by the presence of the parasitic worms.
Laboratory tests, such as skin biopsies or blood tests, may be performed to confirm the presence of Onchocerciasis infection. Skin biopsies can be used to detect the presence of microfilariae (larval forms of the parasitic worm) in the skin, while blood tests can help identify antibodies or antigens specific to Onchocerca volvulus. These tests can provide additional confirmation of the diagnosis and help guide treatment decisions.
💊 Treatment & Recovery
Treatment for 1F6A.0, also known as Onchocerciasis of the eye, typically involves the use of antiparasitic medications. The most commonly prescribed medication for this condition is ivermectin, which is known to effectively kill the adult worms responsible for the infection. In some cases, additional medications such as doxycycline may be prescribed to target the bacteria that live symbiotically with the parasites.
In more severe cases of Onchocerciasis of the eye, surgery may be necessary to remove the adult worms or to relieve pressure on the eye caused by inflammation. Surgical interventions may include procedures to remove nodules or cysts that have formed in the eye or to repair damage to structures such as the cornea or retina. These procedures should be performed by experienced ophthalmologists specialized in the treatment of parasitic infections.
Recovery from Onchocerciasis of the eye depends on the severity of the infection and the effectiveness of the chosen treatment. In cases where the infection is caught early and treated promptly, patients may experience a full recovery with little to no long-term effects on their vision. However, in cases where the infection has caused significant damage to the eye, recovery may be slower and may require ongoing monitoring and treatment to manage complications such as glaucoma or cataracts. Regular follow-up appointments with an ophthalmologist are essential to track the progress of treatment and ensure optimal outcomes for patients with Onchocerciasis of the eye.
🌎 Prevalence & Risk
In the United States, onchocerciasis of the eye, also known as river blindness, is extremely rare. This is due to successful public health efforts to control the disease and prevent its spread. Cases of onchocerciasis in the U.S. are usually limited to individuals who have traveled to endemic regions.
In Europe, onchocerciasis of the eye is also rare. The disease is more commonly found in areas with a tropical climate that support the black fly vector responsible for transmitting the parasite. However, sporadic cases of onchocerciasis may occur in individuals who have traveled to endemic regions and returned to Europe.
In Asia, onchocerciasis of the eye is predominantly found in countries such as Yemen, Sudan, and Ethiopia. The prevalence of the disease in these regions is higher due to a combination of factors, including poverty, lack of access to healthcare, and limited resources for disease control programs. Efforts are being made to control and eliminate onchocerciasis in affected Asian countries.
In Africa, onchocerciasis of the eye is most prevalent, particularly in sub-Saharan regions. It is estimated that over 99% of the worldwide cases of onchocerciasis occur in Africa. The disease is endemic in many countries on the continent, with millions of individuals at risk of infection. Control programs, such as mass distribution of medication and vector control efforts, are ongoing in Africa to reduce the burden of onchocerciasis.
😷 Prevention
Onchocerciasis, commonly known as river blindness, is a parasitic disease caused by the filarial worm Onchocerca volvulus. The disease is transmitted to humans through the bites of blackflies of the genus Simulium. The larvae of the worm mature into adult worms, which release microfilariae that migrate to the skin and eyes, causing severe itching, skin lesions, and ultimately blindness if left untreated.
Preventing onchocerciasis primarily involves controlling the blackfly populations that transmit the disease. This can be achieved through vector control measures such as larviciding, insecticide spraying, and environmental modifications to eliminate breeding sites. Additionally, mass drug administration programs with the drug ivermectin have been successful in reducing transmission of the parasite and preventing the development of eye disease in endemic areas.
Community education and awareness play a crucial role in preventing onchocerciasis of the eye. Educating at-risk populations on the importance of avoiding blackfly bites, maintaining personal hygiene, and seeking early treatment for symptoms can help reduce the spread of the disease. Health education campaigns can also promote the importance of regular screening and treatment to prevent blindness and other complications associated with onchocerciasis. By implementing a combination of vector control measures, mass drug administration programs, and community education efforts, the burden of onchocerciasis of the eye can be significantly reduced.
🦠 Similar Diseases
In the realm of diseases similar to 1F6A.0, or Onchocerciasis of the eye, one comparable condition is pterygium (H11.0). Pterygium is a growth of pink, fleshy tissue on the conjunctiva lining the inner corner of the eye. While not directly caused by parasitic infection like Onchocerciasis, pterygium can also affect vision and may require surgical removal in severe cases.
Another disease akin to Onchocerciasis is glaucoma (H40.9). Glaucoma is a group of eye conditions that damage the optic nerve, often due to elevated intraocular pressure. Though distinct in etiology from Onchocerciasis, glaucoma can also lead to vision loss if left untreated. Regular eye exams are crucial in detecting glaucoma early and preventing irreversible damage.
Lastly, trachoma (A71.9) is a disease with similarities to Onchocerciasis in its impact on vision and ocular health. Trachoma is caused by the bacterium Chlamydia trachomatis and can lead to scarring of the eyelids, cornea, and eventual blindness if left untreated. Like Onchocerciasis, trachoma disproportionately affects populations in developing countries with limited access to healthcare and sanitation.
