OpenVision 0.1.0 (pre-release)

Pre-release. Not for real patient data until an eye-care professional has reviewed it (that review is what 1.0 will mean). Try it with made-up patients.

Install (Windows 10/11, 64-bit)

1. Download OpenVision-Setup.exe below (under Assets).
2. Run it and approve the administrator prompt. The installer is not code-signed yet, so Windows SmartScreen may say "Windows protected your PC": click More info, then Run anyway.
3. Read and accept the data safety notice and the Terms of Use.
4. Open OpenVision. The first screen creates your administrator account and then offers to download your diagnosis codes (ICD-10-CM or WHO ICD-11).

Your data stays on this computer in C:\ProgramData\OpenVision. OpenVision does not encrypt its database yet, so turn on BitLocker and keep backups. Updates are offered automatically from this page, with a backup taken first.

Check your download (optional): the SHA-256 fingerprint of OpenVision-Setup.exe is
668d53e2a62fadd637a8f58a67f9457c02a469ef77eb3ab7fdae70e74200db8c
(also in SHA256SUMS.txt). In PowerShell, Get-FileHash .\OpenVision-Setup.exe should print the same value.

The first release. Everything below is new.

Exam

• Sections: HPI (three complaints, elements, chronic problems from history), review of systems, vision
  (acuity, Amsler), IOP / pupils / confrontation fields, refraction (current glasses, manifest,
  cycloplegic, autorefraction, contact lens, transpose), external, slit lamp, fundus, neuro (motility,
  alternate cover test, color, stereo, NPC, amplitudes).
• Shorthand bar (Alt+K, e.g. das; rc:1+ inj), normal defaults, copy between eyes, per-provider quick
  picks, prior visits with copy forward, undo, autosave, keyboard section switching.
• Drawings: own canvas for touch and pen, versioned autosave, prior drawings.
• Impression and plan builder from exam findings and history, with orders and next visit; diagnosis codes
  from ICD-10-CM (FY2027) or WHO ICD-11 (2026-01), chosen per practice.
• Billing aid only: visit and test code suggestions with their reasons, modifiers and justifiers, printed for
  the practice's own billing system; OpenVision never bills. US code suggestions can be switched off.
• Exam locking while someone edits, final electronic signing with dated addenda.

Records and output

• Patients and visits; explicit allergy states (not recorded, no known allergies, listed); past eye and
  medical history, surgeries, medications, family and social history.
• Documents and images per patient and exam area; visual-acuity history; glaucoma flow sheet with IOP
  targets.
• Printable exam reports (one or many visits), spectacle and contact-lens Rx, PDF, CSV and
  FHIR R4 export (impression and plan as Conditions); every print and export is audit-logged.

Access and safety

• Sign-in with roles (admin, provider, technician), automatic logoff after inactivity, an append-only audit
  log of sign-ins, settings changes and chart views, emergency admin reset from the computer.

Languages and code sets

• Six interface languages: English, and drafts awaiting native review in Spanish, French, Chinese
  (Simplified), Hindi and Arabic (right-to-left layout).
• Code sets are downloaded by the practice (or imported offline), checked against pinned releases; WHO
  ICD-11 titles can be added in Spanish, French, Chinese, Arabic and other languages WHO publishes.

Windows desktop app

• Installer for Windows (Electron): runs without a browser, server inside the app on 127.0.0.1 only,
  data in C:\ProgramData\OpenVision restricted to the OpenVision Users group, automatic updates from
  GitHub Releases with a database backup first, Save-as-PDF, warning when the drive is not encrypted
  (BitLocker). Installers are not code-signed yet.
• Terms of Use, Privacy Policy and a data safety notice, accepted in the installer and at first-run setup.

Found in external review and fixed before release

• A signed exam is now final in the database too: triggers refuse changes to its findings, drawings, plan,
  orders, chosen codes and visit documents.
• The server checks the signature and edit lock after a request arrives, inside the same transaction as the
  change, so a slow save cannot land after signing; a provider or technician change and its audit entry are
  saved together.
• Past-history items are never overwritten or erased: each edit or delete keeps the earlier version, and a
  deleted item is only hidden.
• Signing stores the patient history as shown in the exam; a signed report prints that history, labelled with
  the signing date.
• Every print is in the audit log as well as the print log, and the print log cannot be edited or deleted.
• Installing a newer version by hand backs up the database before upgrading it; if the backup fails, nothing
  is changed and the app does not start.
• Empty past-history categories on the report say "Not recorded", never "None".
• Signing first saves everything still open on the page and stops if anything could not be saved; plan items
  and orders save one request at a time, so the last change is the one kept.
• The installer resets old permissions on the data folder and stops if it cannot protect it.
• Old unfinished downloads in the data folder are deleted when the app starts.
• Choosing "Wait" when closing with changes still saving now really cancels the exit or restart.
• CSV and FHIR exports carry the signature and addenda, with a signed visit's allergies as recorded at
  signing; printed prescriptions and opened or downloaded documents are in the audit log, which now has
  readable labels.
• The glaucoma flow sheet's default IOP target comes from the visit's provider, not whoever is viewing, and
  says whose it is.
• Transpose refuses a blank sphere (type PLANO for zero) or a blank or invalid axis instead of guessing.
• A temporary password blocks everything except changing it, signing out and the session check.

Known limits

• The database is not encrypted by OpenVision (planned); use BitLocker.
• Desktop menus are in English only; the Terms, Privacy Policy and notice are in English only.
