Ophthalmology Toolbox

A pocket toolbox for ophthalmology. Eight clinical screening and reference tools in one native iOS app — built for ophthalmologists, optometrists, residents, and medical students.

Designed for the bedside, the clinic, and the corridor. Every tool is one tap away from the Home Screen.

WHAT'S INSIDE

• Eye Drops Guide - a mini-handbook A searchable medication reference covering drug names, classes, forms, concentrations, doses, safety profiles, drug interactions, and more.

• VA Conversion Table Meter, Feet, and decimal acuities side-by-side. Convert at a glance.

• Retina Viewer Smartphone fundus photography using a 20D lens. Live camera with zoom, capture photos or video, save to Photos.

• Nine-Gaze Camera Guide the patient through the nine cardinal gaze positions. The app auto-stitches each frame into a single 3×3 motility montage, ready to save.

• Ishihara Test 24-plate color vision screening with a built-in 1–15 scoring table and a protan/deutan classification breakdown. An evidence-appraisal section cites validation studies for digital Ishihara screening — with links to the original papers.

• IPD Measurement Measure interpupillary distance via the TrueDepth front camera.

• Amsler Grid On-screen central vision testing for macular monitoring.

• Cobalt Blue Screen Blue illumination for fluorescein when a cobalt blue light source isn't available — a workaround for low-resource and emergency settings.

DESIGNED FOR CLINICIANS

Each tool is built around the way clinicians actually work: short workflows, contextual help sheets with the technique and limitations spelled out, and no marketing fluff. Home Screen quick actions surface the most-used tools — VA Conversion, Search Medications, Cobalt Blue Screen — in one long-press.

A NOTE ON SCOPE

Ophthalmology Toolbox is a clinical reference and screening companion. It is not a substitute for slit-lamp examination, formal perimetry, or standard ophthalmic equipment when those are available. The Cobalt Blue Screen and digital Ishihara test are best treated as bedside workarounds, with printed plates or proper equipment used to confirm significant findings.

JUST THE BEGINNING The toolbox is still growing. More clinical utilities and mini-handbooks for common conditions — workups, differentials, examinations — are queued for upcoming releases. If something's missing from your workflow, send a note: the next update might add it.
