Modular lens adapters for mobile anterior and posterior segment ophthalmoscopy

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, and
• wherein 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.
