Cataloged from PDF version of thesis. Includes bibliographical references (pages 68-77). Eye exams via a slit lamp are critical in screening for conditions such as cataracts, corneal opacities and pterygia early on to avert vision loss. The slit lamp, however, is a purely qualitative optical device that is bulky, expensive, can cause eye discomfort due to light sensitivity. It also requires a trained physician to operate, making it unsuitable for large-scale screening in resource-constrained settings. In this thesis, we propose a spectrum of portable anterior segment imaging solutions that can be operated by minimally trained health workers. On one end, we present a smartphone attachment with minimal optics and no electronic components beyond what is present in the smartphone itself to examine and image the anterior segment of the eye. This cost-effective, easily scalable solution would help extend the reach of anterior segment examination to extremely resource constrained settings, such as mass-screening camps, mobile ophthalmology clinics, war zones etc. On the other end, we propose purely solid-state instrumentation that employs programmable illumination and light steering optics to simulate the motion of a slit on the eye, thereby exhibiting functionality similar to that of a slit lamp with no moving parts. Finally, we discuss potential deployment strategies for two implementations of this technology in the specific cases of two contrasting healthcare systems in India. by Shantanu Sinha.
