In vivo confocal microscopy (IVCM) has been used in clinical settings for more than 25 years, and is noninvasive, rapid and easily repeatable technique to investigate ocular surface disorders. It enables morphological and quantitative analysis of ocular surface microstructure. [1-3] As the technology advances, new IVCM machine, Heidelberg Retinal Tomograph with Rostock Corneal Module (HRT-RCM), was developed. Hardware and software modifications and acquisition techniques continue to expand the applications of the HRT-RCM for quantitative in vivo corneal imaging at the cellular level. The new software can access the corneal nerve more accurate. Here the investigators proposed this Institutional Review Board (IRB) to collect healthy persons and cases of different systematic diseases as well as etiologies of ocular surface diseases.

Ocular Surface Dry Eye Microbiome

Dry Eyes

The investigators seek to characterize the identity of all microorganisms residing on the eye's surface (conjunctiva) in healthy eyes and those with dry eye syndrome, using a combination of analyses. Dry eye disease is thought to have an inflammatory basis and in the vast majority of cases the cause of the chronic inflammatory condition is unknown.

Optical Coherence Tomography of Ocular Structures in Epiphora and Dry Eye Syndrome.

Dry Eye SyndromeEpiphora1 more

The primary aim of the study is to investigate whether optical coherence tomography (OCT) may be a useful tool for investigating the in-vivo histology of ocular structures in patients with tear film pathology. In epiphora the investigators will image the proximal lacrimal system. In dry eye syndrome the investigators will image the lacrimal gland and also the buccal mucosa. The secondary aim of the study is to investigate the appearance of the normal cornea and conjunctiva under OCT imaging.
