Ebola survivors can lose their eyesight
SEE ALSO :Congo Ebola spreading faster: WHOGiven that thousands of Ebola survivors reside in West Africa, the global community also learned about the high risk of health complications after acute Ebola virus disease. Research done so far has identified a range of complications. These include arthritis, abdominal pain, mental health as well as eye complications. We have done extensive investigation on how Ebola affects the vision of people who have survived the disease. So far we have established that an inflammatory disease of the eye develops in around 25% of survivors and the risk increases over time. To take our earlier patient care and research forward, we recently partnered with the Ministry of Health in the DRC and the World Health Organisation Global Outbreak and Alert Response Network to evaluate Ebola survivors in the DRC.

This led to a better understanding of how uveitis affected vision, and the development of treatment protocols for medical and surgical care. The insights we gained in West Africa directly informed the work we are doing with Ebola survivors it the DRC. Translating lessons In March this year ophthalmologists worked together to conduct an “Eye Care in Ebola Survivor” symposium for 10 ophthalmologists from multiple cities in DRC. The cities they came from included Bukavu, Butembo, Bunia, Goma, and Kinshasa. The training symposium provided a forum to discuss eye complications associated with Ebola, the current status of eye care in the DRC as well as ways of strengthening vision care in the region. We also discussed case presentations to learn to distinguish Ebola from other infectious diseases. After the training we screened more than 250 survivors for eye disease and treated their ailments. The eye problems we found included uveitis, retinal scarring, corneal disease and glaucoma. While some of these, such as uveitis and retinal scarring, have been associated with Ebola, others were non-specific. This emphasised the need for a range of ophthalmic care in the eastern DRC. Strikingly, nearly one-third of survivors requiring eye examinations were infants and children. This underscores the need for vision care services for paediatric patients. This is the earliest that an intervention has been put in place during an Ebola outbreak. The hope is that it will significantly reduce long term damage to people’s eyes. Continuing surveillance Although the Ebola outbreak in West Africa taught the global community about uveitis and the danger of vision impairment, translating these lessons into improved vision health remains an ongoing necessity in the DRC. A key component of survivor health includes counselling patients on the risk of uveitis and the symptoms they should be aware of so they can seek urgent eye care. Surveillance of eye disease in survivors remains critical – given the security concerns and instability, community mistrust, and funding gaps, the growing Ebola outbreak will require ongoing ophthalmic support.
