If your patient is a unilateral myope, sometimes the myopic eye is the easier one to manage! This case study explores the options to appropriately diagnose, track and manage the non-myopic eye in a unilateral myope – where the non-myopic eye seems to be progressing faster than the myopic eye treated with orthokeratology.
Most clinicians are aware of myopia risk factors such as family history and visual environment, but how about axial length? This article explores how we can use the current axial length value, change in axial length, axial length growth charts, and another metric, the axial-length-to-corneal-radius (AL/CR ratio), to predict risk of a child developing myopia.
What amount of axial length growth be expected in myopes versus emmetropes, and how can you tell if your myopia control treatment is working? This important clinical reference provides all this information and more on axial growth in younger and older children, emmetropes and myopes, and even data on typical myopia stabilization.
The Erasmus Medical Group in the Netherlands set out four steps in their myopia management protocol: providing visual environment advice, identifying high-risk myopes by axial length and treating them with atropine 0.5%, managing other myopes with optical treatments or lower-concentration atropine, and ceasing treatment in the late teens once axial length is stable. The described use of axial length percentile growth charts for diagnosis, choice of treatment, monitoring and cessation is a world-first.
Axial length typically increases in children, and myopia control aims to slow this excessive growth. Can axial length regression or reduction be possible in myopia control? In this case study, an 8-year-old appears to show a large reduction in axial length. We investigate possible causes and provide clinical guidance on measurement accuracy.
