Insights
Cornea and lens pathologies are leading causes of childhood blindness in Burundi. Many cases lack identified causes, highlighting the need for enhanced public health and pediatric eye care services.
Area of Science:
- Ophthalmology
- Public Health
- Pediatrics
Background:
- Childhood blindness and severe visual impairment pose significant challenges in low-resource settings.
- Understanding the specific etiological factors is crucial for effective intervention and service planning.
Purpose of the Study:
- To identify the causes of childhood blindness and severe visual impairment among students in schools for the blind in Burundi.
- To inform the planning and development of essential eye care services for children in the country.
Main Methods:
- A comprehensive eye examination was conducted on pupils attending three schools for the blind in Burundi.
- Data collection utilized a modified World Health Organization/Prevention of Blindness and Visual Impairment (WHO/PBL) eye examination record form.
- Analysis focused on visual impairment that occurred before the age of 16 years.
Main Results:
- 117 pupils with visual impairment before age 16 were examined, with 109 (93.2%) classified as blind or severely visually impaired.
- The primary anatomical causes were cornea pathology/phthisis (23.9%), lens pathology (18.3%), uveal lesions (14.7%), and optic nerve lesions (11.9%).
- The underlying etiology of visual loss remained unknown in a significant majority of cases (74.3%). Poor surgical outcomes were noted for lens-related blindness.
Conclusions:
- Identified causes underscore the need for sustained public health strategies and specialized pediatric ophthalmology services in Burundi.
- The study highlights the importance of community-based programs for early identification and referral of children with visual impairments.
- Addressing unknown etiologies and improving surgical outcomes are critical for managing childhood blindness effectively.
Purpose:
To determine the causes of childhood blindness and severe visual impairment in pupils attending schools for the blind in Burundi in order to assist planning for services in the country.
Materials And Methods:
All pupils attending three schools for the blind in Burundi were examined. A modified WHO/PBL eye examination record form for children with blindness and low vision was used to record the findings. Data was analyzed for those who became blind or severely visually impaired before the age of 16 years.
Results:
Overall, 117 pupils who became visually impaired before 16 years of age were examined. Of these, 109 (93.2%) were blind or severely visually impaired. The major anatomical cause of blindness or severe visual impairment was cornea pathology/phthisis (23.9%), followed by lens pathology (18.3%), uveal lesions (14.7%) and optic nerve lesions (11.9%). In the majority of pupils with blindness or severe visual impairment, the underlying etiology of visual loss was unknown (74.3%). More than half of the pupils with lens related blindness had not had surgery; among those who had surgery, outcomes were generally poor.
Conclusion:
The causes identified indicate the importance of continuing preventive public health strategies, as well as the development of specialist pediatric ophthalmic services in the management of childhood blindness in Burundi. The geographic distribution of pupils at the schools for the blind indicates a need for community-based programs to identify and refer children in need of services.

Photoreceptors
The retina is composed of several layers and contains specialized cells called photoreceptors. The photoreceptors (rods and cones) change their membrane potential when stimulated by light energy. There are two types of photoreceptors—rods and cones—which differ in the shape of their outer...
