The primary function of the lacrimal system is to produce and drain the tear film from the surface of the eye. The tear film is composed of three integrated layers: the aqueous, mucus, and lipid layers. The aqueous layer is produced by the orbital lacrimal gland and gland of the third eyelid and secreted onto the ocular surface through ductules that traverse the conjunctiva. The mucus layer is ...
PURPOSE To discuss the importance of ocular surface management in corneal transplantation, especially in limbal transplantation. METHODS Since the corneal epithelium is not completely recovered after corneal transplantation, meticulous attention should be paid to the ocular surface to prevent infection and rejection, which are the major causes of corneal transplantation failure. Preoperative ...
OBJECTIVE To examine whether women with premature ovarian failure (POF) have abnormal findings in ocular surface or tear parameters and whether they report symptoms of ocular discomfort compared with age-matched controls. METHODS Sixty-five patients with POF and 36 age-matched healthy controls were examined for signs and symptoms of dry eye. The Ocular Surface Disease Index questionnaire and ...
Purpose Pain sensitivity has been identified as a factor that affects how individuals answer dry eye questionnaires, but it is unknown how it affects ocular discomfort. This study used the time that individuals could refrain from blinking as an indicator of ocular discomfort and set out to determine whether it was related to pain sensitivity, while adjusting for ocular surface conditions. Met...
BACKGROUND The objective of this study was to determine the prevalence of symptoms of ocular surface disease and its relationship with associated risk factors in students from the University of Monterrey using Ocular Surface Disease (OSDI) questionnaire. METHODS A cross-sectional survey was conducted between October and December 2014 to assess the prevalence and risk factors for ocular surfac...
The surface of the eye is an extraordinary and vital component of vision. The smooth, wet surface of the cornea is the major refractive surface of the visual system, which, along with corneal transparency, enables light to proceed through the lens and onto the retina for photoreceptor activation. The presence of the smooth, wet refractive ocular surface required for vision comes, however, at a ...
OBJECTIVE The international criteria for primary Sjögren's Syndrome (SS I) diagnosis (Vitali et al. 2002) include the Schirmer test I and vital dye staining as tests for ocular surface involvement, but diagnosis can be reached also when the item for ocular signs is not satisfied. The purpose of our study was to evaluate the ocular surface in patients with Sjögren's Syndrome, non-Sjögren's autoi...
PURPOSE To assess the change in ocular surface temperature between healthy phakic and pseudophakic patients. METHODS We included patients with no history of ocular disease other than cataract. Patients were divided into three groups: clear lens, cataract, and pseudophakic. All patients had two ocular surface digital thermal scans. An average of five surface points was used as the mean ocular ...
