Dr Ashish Markan on Instagram: "Schirmer test is a simple eye examination that measures tear production using a small strip of filter paper placed inside the lower eyelid for five minutes. It helps diagnose dry eye syndrome (keratoconjunctivitis sicca) or excessive watering by indicating if the lacrimal glands are producing enough tears to keep the eye moist. #eyedoctor #yourretinadoctor #retinaspecialist #eyehealth #eyehealthtips #dryeye #dryeyerelief #dryeeyetest"
