Purpose: To estimate the prevalence of non-infectious corneal diseases in the city of Baku.

Material and Methods: We retrospectively reviewed databases of the outpatient polyclinics of the city of Baku in which the activities of ophthalmological departments were coordinated by the Acad. Zarifa Aliyeva National Ophthalmology Centre. Non-infectious corneal diseases were diagnosed on the basis of the clinical guidelines established by, and with involvement of specialists and equipment from the Acad. Zarifa Aliyeva National Ophthalmology Centre.

Results: The most common clinical form was foreign body (54.0 ± 1.5 0⁄0000), followed by traumatic corneal erosion (47.7 ± 1.4 0⁄0000) and keratoconus (24.6±1.0 0⁄0000); chemical and thermal burns were less common (6.1 ± 0.5 0⁄0000). The age group of 0-9 years had the least prevalence (63.1 ± 4.3 per 100,000) and the age group of 101-9 years, a more than twice higher prevalence (120.9 ± 7.0 0⁄0000 per 100,000) of total non-infectious corneal diseases. The next two age groups had statistically increased prevalences of these diseases, 152.1 ± 6.1 and 262.5 ±9.2 0⁄0000, respectively.

Conclusion: Estimated prevalence of non-infectious corneal diseases at a population level was 166.9 ± 2.7 0⁄0000, with the most common clinical form being foreign body (54.0 ± 1.5 0⁄0000), followed by traumatic corneal erosion (47.7 ± 1.4 0⁄0000), keratoconus (24.8 ±1.0 0⁄0000), and corneal dystrophy and degeneration (16.1 ± 0.8 0⁄0000). The age group of 60-69 years had the highest prevalence of total non-infectious corneal diseases (275.9 ± 12.6 0⁄0000), and foreign body prevalence was highest in the age group of 40-49 years (117.6 ± 6.2 0⁄0000), the prevalence of corneal dystrophy and degeneration was highest in the age group of 70-79 years (93.2 ± 12.0 0⁄0000), and the prevalence of traumatic corneal erosion was highest in the age group of 60-69 years (130.6 ± 8.7 0⁄0000).
