摘要

Purpose

To describe trends in childhood certificate of visual impairment (CVI) registrations over a 10-year period (2010–2019) at Alder Hey Eye Clinic, a tertiary centre serving Merseyside and parts of Wales, and to compare findings with a previously published cohort (1997–2006).

Methods

We retrospectively reviewed records of children registered as sight impaired (SI) or severely sight impaired (SSI) between 2010 and 2019, extracting demographic and clinical data. We conducted a comparative analysis against the published report describing the 1997–2006 registered cohort.

Results

384 children were certified between 2010 and 2019, representing a 50% increase from 256 in 1997–2006. The median age at registration was 73.9 months (IQR 13–106), comparable to the earlier cohort (76 months, range 1–192). Gender distribution remained stable (57.8% vs. 58.2% male, P = 0.9). The proportion of White British children declined (80% vs. 94%, P < 0.05). Certification as SI increased from 48% to 62.8% (P < 0.05). The new cohort showed wide variation in visual acuity (VA) (median 1.0 logMAR, IQR 0.9–3.4). 52% had VA of 1.0 logMAR or worse, whereas 15% had VA ≤ 0.4 logMAR but qualified due to visual field or higher-order deficits. Of the earlier cohort, 47% had VA of 1.0 logMAR or worse. Cerebral visual impairment increased from 27% to 33.9% (P = 0.06), while other causes remained stable.

Conclusions

The number of registered children increased, particularly among those with milder impairment. Cerebral visual impairment and optic atrophy were leading causes of registration between 2010 and 2019, mirroring national trends.
