Smartphone-based handheld ophthalmic examination devices

Abstract

Various examples of methods, systems and devices are provided for ophthalmic examination. In one example, a handheld system includes an optical imaging assembly coupled to a user device that includes a camera aligned with optics of the optical imaging assembly. The user device can obtain ocular imaging data of at least a portion of an eye via the optics of the optical imaging assembly and provide ophthalmic evaluation results based at least in part upon the ocular imaging data. In another example, a method includes receiving ocular imaging data of at least a portion of an eye; analyzing the ocular imaging data to determine at least one ophthalmic characteristic of the eye; and determining a condition based at least in part upon the at least one ophthalmic characteristic.

Therefore, at least the following is claimed: 
     
         1 . A handheld ophthalmic examination system, comprising:
 an optical imaging assembly coupled to a user device; and   the user device comprising a camera aligned with optics of the optical imaging assembly, the user device configured to:
 obtain ocular imaging data of at least a portion of an eye via the optics of the optical imaging assembly, and 
 provide ophthalmic evaluation results based at least in part upon the ocular imaging data.
