A retina checkup to the cat, boji by smartphone

Animals suffer from eye problems that are similar to those which affect humans. These problems include cataracts, glaucoma, dry eye, corneal ulceration, tumors of the eye, eyelid defects, inflammation of the eye and surrounding tissues, retinal degeneration, and many others. Owners may notice a loss of vision, a change in the appearance of the eye, discharge, pain, or a combination of these symptoms. Most cases seen by a veterinary ophthalmologist are referred by a general practice veterinarian. This individual is in the best position to provide an initial examination and determine if a referral to a specialist is indicated.

Vision in general is complex and involves many environmental and anatomic factors.

Cat’s eyes function quite similarly to our human eyes but they have differences due to their anatomy that make their vision slightly different in some aspects.

The previous concept is the cornerstone for building a smartphone fundoscope for animals like dogs, cats, and horses.

What’s a smartphone fundoscope?

A device that turns any smartphone into a fundus camera.. a whole retina checkup for the animal can be fulfilled by only a smartphone.

Animals’ vision always depends on many factors like the condition of the cornea, lens, and retina…

cornea and lens lesions are always checked by portable slit-lamp while the retina is mostly missed due to the difficulty of its examination. also the lack of an indirect ophthalmoscope and that hustle of bringing in the animal and setting it for examination.

Retina Checkup is now more possible than ever. easier than ever.

the smartphone fundoscope offers portability, low cost, and the best practice for ophthalmology vets.

let’s explain more;


The device requires only attaching the smartphone to it, is less than 100gm weight, is 20cm long & no wires at all.

Lowest Cost

That concept of turning the smartphone into a fundus camera has been developed to replace indirect ophthalmoscope hustle and save 70% of the budget!

the device uses smartphone gear and turns it into a 4k camera that visualizes the retina on the smartphone screen. record the whole exam in video mode.

Best Practice

Capturing images of the retina and recording the whole exam of the retina, the device adds great value to the exam. allowing the Vet. to explain the condition more perfectly to the animal owner.

offer the best way to follow up a retina: capture it.. wait for the treatment to do its magic.. capture it again. compare both retina images.

How smartphone fundoscope works ?!

The device consists of a light source, 22D lens, and attachment ring for the smartphone…
Once the phone is attached, the light source will be turned on automatically.
