ABSTRACT

OBJECTIVES: To determine the rate of myopia progression in children fit with a commercially available extended depth of focus (center distance) multifocal soft contact lens with attributes theoretically expected to slow the progression of myopia. METHODS: A retrospective case series analysis of 32 patients (ages 6-19 years, mean 10.98±2.95) from 10 practice locations was performed. At initial presentation, 44% wore spectacles, 37.5% spherical soft contact lenses, 15.6% a different soft multifocal contact lens, and 3% orthokeratology lenses. All participants showed progression of at least -0.50 diopter with current corrections and were fit with an extended depth of focus (center distance) multifocal soft contact lens (NaturalVue Multifocal 1 Day Contact Lenses; Visioneering Technologies, Inc., Alpharetta, GA). Follow-up time was 6 to 25 months (mean: 10.94±4.76). RESULTS: Reductions in the annualized rate of myopic progression from -0.85 D per year ±0.43 D to -0.04 D per year ±0.18 D (P<0.00000) OD, -0.90 D per year ±0.57 D to -0.03 D per year ±0.17 D (P<0.00000) OS were observed. These data represent a reduction of 95.4% OD and 96.25% OS. Approximately 98.4% of the children showed reduction of annualized myopic progression; 91% showed a decrease of 70% or greater. Overall, 81.25% showed complete halting of myopic progression, including 6.25% demonstrating myopic regression. CONCLUSIONS: This unique extended depth of focus (center distance) daily disposable multifocal contact lens was effective in slowing myopic progression in these children. These findings add to the growing evidence that center distance multifocal soft contact lenses may slow the progression of myopia.

ABSTRACT

Objective To assess the additive value of prenatal chromosomal microarray analysis (CMA) for all indications and the likelihood of detecting pathologic copy number variations (CNVs) based on specific indications. Methods A retrospective analysis was performed on amniocentesis and chorionic villi sampling results obtained between 2010 and 2014 in a single institution. A total of 3,314 consecutive patients undergoing invasive genetic testing for different indications were offered CMA in addition to standard karyotype. The prevalence of pathologic CNVs was compared between patients with low-risk indications and those with high-risk indications. Likewise, the prevalence of pathologic CNVs among patients with different sonographic abnormalities was calculated and compared with the low-risk group. Chi-square and Fisher exact tests were used for statistical analysis. Results The prevalence of pathologic CNVs was significantly higher in patients with high-risk indications and specifically those with sonographic abnormalities, compared with the low-risk group (2.8 and 5.9% vs. 0.4%, respectively; all p < 0.05). Conclusion Prenatal CMA detected clinically relevant CNVs in fetuses with a normal karyotype. Major structural malformations and nuchal translucency (NT) ≥ 3.0 mm are associated with the highest risk for a CMA abnormality. Nevertheless, the prevalence of pathologic CNVs in the low-risk population was high enough (1:250) to consider genetic counseling in this group.
