Abstrakt: Clinical Relevance: Myopia prevention and anti-myopia treatment is of great importance in South East Asia.
Background: To evaluate the prevalence and related factors of myopic retinopathy in Vietnam.
Methods: A cross-sectional study was conducted on 168 eyes of 88 patients with high myopia presenting to the Refraction Department of Vietnam National Eye Hospital. Inclusion criteria were high myopia (≤-6.00D with cycloplegic retinoscopy). Consecutive presenting patients recruited between January 2020 and August 2020 consented to participate.
Results: Participant age range was 12-47 years. Peripapillary atrophy was present in 70.2% of participants, most commonly atrophy of one-quarter of the disc (38.7%). Central retinal changes were present in 66.1% of participants, subclassified as tessellated fundus in 60.7%, diffuse chorioretinal atrophy in 4.2% and patchy chorioretinal atrophy in 1.2%. Peripheral retinal lesions were present in 43.5% of participants, consisting of white-without-pressure in 32.1%, lattice degeneration in 16.1%, snail track degeneration in 4.2% and microcystoid degeneration in 1.2%. Myopia ≤-8.00D and axial length ≥26.5 mm were associated with additional risk of posterior ocular complications. Furthermore, age ≥19 years increased risk of central myopic retinopathy and ≥10 years since initial myopia diagnosis increased the risk of peripapillary atrophy and central retinal changes. Other factors such as the age of onset of myopia and family myopia history did not appear to alter the risk of peripheral retina damage.
Conclusions: Retinal disorders were common in Vietnamese people with high myopia. Within the current cohort with high myopia, myopia ≤-8.00D and axial length ≥26.5 mm were associated with a significant further elevation of risk.
