EndMyopia Case Report Registry (v2.0)

An open, structured registry of 344 self-reported adult myopia-reduction case reports (363 cases indexed; 19 excluded from the adult analysis set), drawn from 423 first-person accounts published on endmyopia.org, 2013–2026.

Canonical version — cite this: DOI 10.5281/zenodo.21016339 (concept DOI, always resolves to the latest version). This Hugging Face copy mirrors that deposit; the Zenodo DOI is the citable record of reference.

What this is

A transparent, auditable index of individual adult cases reporting reduction in myopia (nearsightedness), each graded by how well it is corroborated. It exists so the individual-level data can be examined on its merits.

What it is not: a clinical trial, and not a population success rate. The cohort is self-selected and predominantly self-reported. It cannot establish how often the approach works; it documents that individual, measured reductions are on record, with the limitations stated up front.

Scope note: this registry covers the self-reported slice, people who published their own results, largely self-directed on the freely available method. It deliberately excludes the larger program-participant dataset, which is held separately. Treat these figures as a conservative floor rather than a program outcome rate.

Summary figures

Registry-wide (all 363 cases): 423 published reports, 554.3 D total documented reduction, 61 cases carrying a third-party or official-record signal, median rate 1.25 D/yr among cases with a ≥ 12-month window (n = 84).

Adult analysis set (n = 344):

Median starting myopia: −5.00 D (range −0.75 to −13.75; n = 282)
Median recorded reduction: −1.75 D (n = 257; maximum −12.75)
Externally corroborated (third-party exam or official record): 58 / 344 (17%)
Reduction rate, cases with a ≥ 12-month window: median 1.25 D/yr (IQR 0.63–2.00; n = 80)

Every figure above is reproducible from em-case-registry-v2.0.csv with one method: rate = delta_dpt / (timeline_months / 12), gated to windows of 12 months or more.

Verification classes (adult analysis set)

class	n
official record (e.g. driving-license vision record)	12
third-party exam reported	46
dated self-measurements	95
published report, no numbers	51
numbers, method unclear	140

Files

em-case-registry-v2.0.csv — the current registry (363 rows; excluded = True flags the 19 non-analysis rows)
em-case-registry-v2.0.json — same data, JSON records
em-case-registry-v1.0.csv / .json — the superseded v1.0 release, kept for reproducibility of the preprint

Version history

v1.0 (2026-06-10) — initial release from the 2013–2026 published-report archive: 466 reports, 289 cases, verification-classed and person-merged.
v2.0 (2026-07-09) — added 74 self-reported cases documented since v1.0 (three child cases excluded from the adult set, two duplicates merged). 423 reports, 363 cases, 344 in the adult analysis set. Headline figures were recomputed from the file, which moved several numbers off their v1 values; the third-party count changed partly by definition, from a stricter manual review in v1 to a reproducible verification-class count in v2.

Data dictionary

column	meaning
`case_id`	stable case identifier (EM-####)
`verification_class`	strength of corroboration (see table above)
`start_numbers` / `end_numbers`	refraction as stated in the source report
`start_dpt` / `end_dpt`	starting / latest myopia magnitude, diopters (worse-eye sphere)
`delta_dpt`	recorded reduction, diopters
`timeline_months`	reported time window
`timeline_basis`	how the window was derived
`rate_d_yr_12mo_plus`	annualized rate, populated only for ≥ 12-month windows
`member_status`	reporter's relationship to the program
`first_post` / `last_post`	dates of the source post(s)
`n_posts`	number of source posts consolidated into the case
`excluded` / `exclusion_reason`	analysis-exclusion flag + reason (child case / post-LASIK / pending verification)
`source_posts`	link(s) to the original published report(s)

Privacy

All cases derive from reports the participants published publicly. Direct given-name identifiers have been removed from this distribution; individuals may remain inferable from the cited source posts, which are retained for verification. Removal requests: jake@endmyopia.org.

Background

The eye regulates its own axial growth in response to optical defocus, and clinical myopia-control research shows that growth can be slowed in children. Sustained reversal of established adult myopia is not established in the controlled literature, but a flat "impossible" overstates what that literature supports. This registry organizes the otherwise scattered individual reports into one auditable resource, with the numbers and the limitations both on the table.
