Pathologic myopia study

Pathologic myopia study

The Taiwan Journal of Ophthalmology reported on a pathologic myopia (PM) study of choroidal neovascularization (CNV), testing the BCVA (best corrected visual acuity) of 55 PM sufferers against a controlled group of non-CNV people with normal vision.

The average age of the combined CNV group and the non-CNV group was 39.7 years old.  However, the average age of the CNV sufferers was 44.0 +/- 22.9 years old, indicating that “ageing is the major factor” in pathologic myopia (PM).

Anti-VEGF (anti-vascular endothelial growth factor) treatment was given to 21 of the CNV sufferers while the other 34 non-CNV people were the control group and no treatment was given them.  The treatment of the CNV sufferers after over three months of follow up observations resulted in improvement in BCVA or best corrected visual acuity, or more accurately, improvement in unaided vision or vision without correction.

[Master Chen Says]  This is a good example illustrating the argument that the term BCVA is an inaccurate label, and that the argument for the more correct description should be unaided vision and vision without correction.
