Childhood blindness in Uzbekistan

Area of Science:

• Ophthalmology
• Public Health
• Pediatrics

Background:

• Childhood blindness presents a significant public health challenge globally.
• Understanding the specific causes of vision impairment in children is essential for targeted interventions.
• Uzbekistan's demographic and healthcare landscape necessitates a focused study on pediatric visual health.

Purpose of the Study:

• To determine the underlying causes of childhood blindness in Uzbekistan.
• To evaluate the current and future requirements for pediatric ophthalmic services in the country.
• To inform strategies for the prevention and management of visual impairment in Uzbek children.

Main Methods:

• A comprehensive eye examination was conducted on 671 children across seven schools for the visually impaired in Uzbekistan.
• The World Health Organization/Prevention Of Blindness (WHO/PBL) childhood blindness proforma was utilized for data collection.
• Study sites were strategically selected to ensure representative coverage of Uzbekistan's population centers.

Main Results:

• A substantial majority of examined children (75.4%) presented with blindness or severe visual impairment (visual acuity <6/60).
• The leading causes of blindness were cataract-related (35%), retinal dystrophies (24%), and microphthalmos (23%).
• Glaucoma was identified as a cause in approximately 5% of avoidable blindness cases.

Conclusions:

• Unoperated cataracts represent the most common preventable cause of childhood blindness in Uzbekistan.
• The high prevalence of retinal dystrophies may be linked to consanguineous marriage practices.
• Microphthalmos is a significant finding requiring further investigation and comparison with international data.
