Keeler Allpupil II Wired BIO — Used Binocular Indirect Ophthalmoscope

The Keeler Allpupil II Wired Binocular Indirect Ophthalmoscope is Keeler’s purpose-built solution for examination through both dilated and undilated pupils. Its patented all-pupil optical system uses a single control to shift aperture position, allowing the examiner to find a clear path through even a 2mm pupil — eliminating the need to reschedule patients who cannot be dilated or who experience dilation contraindications. With 2,000 lux of illumination and a built-in IR/UV barrier, the Allpupil II delivers sharp, high-contrast fundus images across the full peripheral field.

The clinical significance of pupil size in fundus examination is well established. Research comparing diagnostic outcomes with and without dilation demonstrates that examination capability through smaller pupils directly impacts pathology detection rates — see Amos JF et al., J Am Optom Assoc, 1990 (PMID 2319090).

Why Practices Choose the Keeler Allpupil II Wired BIO

• All-pupil optical design — single control moves the aperture to work through any pupil size, dilated or undilated, without changing lenses or attachments
• 2,000 lux illumination, dimmable to 2% — wide dynamic range lets the examiner protect photosensitive patients while maintaining full field brightness when needed
• Built-in IR and UV filtration — protects patient retinal tissue during prolonged or repeated examination sessions
• Lightweight at 520g — padded headband with 47–75mm IPD range accommodates a full range of clinicians comfortably
• High-contrast optics — neutral xenon/halogen light source delivers natural tissue color rendering for accurate lesion assessment
• Wired design — consistent, uninterrupted power from the transformer; no battery management required
• Wide-angle diffuser included — delivers uniform illumination for full peripheral retinal views

Clinical Applications

The Allpupil II’s ability to examine through small pupils makes it especially useful in settings where dilation is not always practical or possible:

• Emergency retinal evaluation when dilation is contraindicated (e.g., head trauma, narrow-angle glaucoma risk)
• Pediatric and ROP screening where pupil dilation response may be limited
• Diabetic retinopathy surveillance in high-volume primary care settings
• Retinal detachment detection and peripheral tear surveillance
• Vitreoretinal surgical planning and intraoperative use
• General peripheral fundus examination in busy clinics requiring fast patient throughput

Who This Is For

The Keeler Allpupil II Wired BIO is a strong fit for:

• General ophthalmologists and optometrists who frequently encounter patients unable to tolerate full dilation
• Emergency and urgent care eye clinics where dilation may be contraindicated
• Pediatric ophthalmologists performing ROP screening and general fundus surveillance
• High-volume retinal practices looking for a reliable wired BIO at a lower price point than wireless alternatives
• Residency and fellowship programs equipping multiple exam lanes with a versatile teaching BIO
