Modular lens adapters for mobile anterior and posterior segment ophthalmoscopy
First Claim
1. A modular lens adapter system for mobile anterior and posterior segment ophthalmoscopy, comprising:
- (a) a variable intensity light source;
(b) an ophthalmoscopy lens adapter for imaging the posterior segment of an eye,wherein the ophthalmoscopy lens adapter comprises a telescoping arm with a first end and a second end, wherein the first end the telescoping arm comprises a lens mount configured to removably mount an ophthalmoscopy lens and fold relative to the telescoping arm, and wherein on the second end the telescoping arm comprises a mobile imaging device mount configured to removably mount a mobile imaging device comprising a phone, smartphone, or tablet computing device,wherein the telescoping arm can be oriented to position the ophthalmoscopy lens at various distances with respect to a lens of the mobile imaging device,wherein the ophthalmoscopy lens adapter is configured such that the ophthalmoscopy lens is coaxially aligned with the lens of the mobile imaging device, andwherein the variable intensity light source is configured to be coaxially aligned with the lens of the mobile imaging device; and
(c) a macro lens adapter comprising a lens mount configured to mount a macro lens for imaging the anterior segment of the eye, wherein the macro lens adapter is configured to be removably engaged with the mobile imaging device, wherein the variable intensity light source is configured to be coaxially aligned with the macro lens, and wherein the macro lens adapter is configured such that the macro lens is coaxially aligned with the lens of the mobile imaging device.

Abstract
A modular lens adapter system or kit is provided for mobile anterior and posterior segment ophthalmoscopy. Equipped with various lens adapter modules, respective lenses and a mobile imaging device, a user is provided with tools for various mobile ophthalmoscopy imaging applications. Eye care practitioners can use their existing lenses to customize the modular lens adapter system in a cost-effective way, which allows for mobile and remote capture, viewing, and utilization of clinical images. The various modules are also adaptable to nearly any type of phone or tablet regardless of its dimensions or presence of a protective case. The invention also addresses the need for fewer, smaller, less expensive, and easier to use ophthalmic imaging equipment, which is further important in enabling a broad base of users.
