![]() Other associated risks can include abnormal blood vessel growth beneath the retina, and changes in the vitreous cavity within the center of the eye. It is important for patients with high myopia to receive regular dilated eye exams, since this condition is associated with an increased lifetime risk of retinal holes or tears, which can lead to retinal detachment. Lastly, outdoor activity and limiting screen time is known to help reduce myopic progression. Other options include progressive lenses, multifocal contact lenses or bifocals. Orthokeratology (is when a contact lenses worn over night to change the shape of the CTL) is controversial. Low dose atropine has been shown to effectively slow myopia progression and axial length elongation. ![]() ![]() Because more people are developing high myopia, various methods of attempting to slow its progression have been developed. The prevalence of high myopia has been increasing over the last several decades. Parent Code: H44.2 - Degenerative myopia. This means that while there is no exact mapping between this ICD10 code H44.23 and a single ICD9 code, 360.21 is an approximate match for comparison and conversion purposes. High myopia generally begins in early childhood, and continued growth of the eye often means that the corrective lens prescription required to allow proper focus may not stabilize until the early adult years. This is the official approximate match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. Myopia can be corrected by wearing glasses, contact lenses, or refractive surgery. High myopia, also called pathologic myopia is generally defined as near-sightedness of -6.00 diopters or greater or an axial length >26.5mm. It occurs when the optical power of the eye is too high for the corresponding axial length of the eye, resulting in images of distant objects being focused in front of the retina.
