A recent study developed equations to estimate the probability of glaucomatous and non-glaucomatous optic neuropathy in patients with high myopia. The analysis included data from over 35,000 eyes.
Background
High myopia is associated with significant structural risks, including optic nerve damage. Understanding the probability of optic neuropathy in highly myopic patients is important for monitoring and management of ocular health.
Data Highlights
Condition
Prevalence
GLON
2.7%
NGON
0.3%
Key Findings
GLON was present in 2.7% of eyes, while NGON was found in 0.3%.
Most GLON cases had intraocular pressure of 21 mm Hg or below.
GLON probability increased with age and axial length.
In a non-Indian individual, GLON probability rose from 3.5% at age 30 to 60.2% at age 75 with an axial length of 28 mm.
NGON probability increased from 3.4% to 16.4% in the same age range and conditions.
Clinical Implications
Clinicians can utilize these equations to assess optic nerve risk in highly myopic patients.
Conclusion
The findings highlight the need for ongoing assessment of optic nerve risk in high myopia.
