Unfortunately I did not see Dr. McElreath’s email until returning home, I was kept quite busy today! I shadowed the optometric technicians today and watched them go through their normal test protocols. They conduct vision tests both with and without corrections (contact lenses or glasses). They conduct color vision tests without the correction and the depth perception test with correction. They also, if the patient agrees to doing it, take retinal photographs which can allow the optometrist to diagnose the patient with diseases such as glaucoma and eye infections. These photos can also help diagnose diabetes and hypertension. I also watched the technicians go through their process of interviewing the patients. They ask about a variety of things ranging from family medical history to how old a prescription is. I also got to watch how the receptionists in the front checked patients in and out and how information about a given patient is communicated from a technician to the doctor and vice versa. — Viraj
