Generated by Google Gemini Pro 3.0. The main prompts were:

• check the claims in the manually updated wikitext, detect close paraphrasing: [text]
• create wikitext code for claim verification section

Intro and theories of eye growth

• Claim: Peripheral blur is a major factor in myopia progression, and animal studies (like the rhesus monkey foveal ablation study) show peripheral regions guide emmetropization independently.
• Status: Confirmed. The source explicitly notes that peripheral hyperopic blur is a risk factor and that rhesus monkeys still experienced refractive changes after their foveae were ablated, proving the peripheral retina's role (page 71).
• Claim: Blur triggers chemical mediators (dopamine, retinoic acid, nitric oxide) that alter the scleral extracellular matrix and cause the eye to elongate.
• Status: Confirmed. The source identifies these exact biochemical compounds and their role in modulating the choroid and scleral extracellular matrix to cause ocular growth (page 72).

Optical devices and management

• Claim: Single-vision lenses shift the peripheral focal point further behind the retina, worsening with higher prescriptions.
• Status: Confirmed. The text states that single vision lenses increase hyperopic defocus at the periphery, and the magnitude increases alongside the amount of myopia correction (page 73).
• Claim: Progressive lenses showed only about a 0.20 diopter difference over three years, which is statistically significant but clinically modest.
• Status: Confirmed. The source notes a change of 0.20 diopters over a 3-year period that is statistically significant but clinically insignificant (page 73).
• Claim: DIMS (Hoya) and HALT (Essilor) designs use lenslets around a central clear zone and demonstrate roughly 60% efficacy.
• Status: Confirmed. The source describes the DIMS central optical zone surrounded by multiple segments and the Stellest central vision area with radiating aspheric lenslets, confirming both have an effectivity of about 60% (pages 73-74).
• Claim: Orthokeratology flattens the center and steepens the mid-periphery, reducing progression by about 50%.
• Status: Confirmed. The text verifies the lenses flatten the central cornea, steepen the mid-peripheral cornea, and result in an overall myopia progression decrease of around 50% (page 75).
• Claim: Soft lenses range from about 25% to over 70% efficacy.
• Status: Confirmed. The source explicitly states the reduction in myopia progression varies from 25% to over 70% (pages 75-76).
