Disorders of the lacrimal functional unit are common in ophthalmological practice, with meibomian gland dysfunction, blepharitis, and dry eye forming a significant part of the general ophthalmologist's practice. The eyelid and its associated structures form a complex organ designed to protect the fragile corneal surface and improve visual acuity. This organ is subject to a number of disorders, including meibomian gland dysfunction, dry eye syndrome, anterior blepharitis, allergic and dermatological conditions, and disorders associated with contact lens use. Although commonly described separately, disorders of the lacrimal function unit are better considered as a group of interacting pathologies that have inflammatory mediators as a central feature. Eyelid hygiene, in the sense of routine cleansing and massage of the eyelids, is well accepted in the management of many disorders of the eyelid. However, a broader concept of eyelid health may be appropriate, in which eyelid cleansing is but a part of a more complete program of care that includes screening and risk assessment, patient education, and coaching. The ophthalmologist has an important role to play in helping patients persist with routine eyelid care that may be long-term or lifelong. A number of preparations exist to make routine eyelid care both more effective and more pleasant, and might also improve compliance. Several such preparations have been devised, and are being assessed in clinical studies, and appear to be effective and preferred by patients over traditional soap and water or baby shampoo.

    • "The ocular surface (OS) constituents (cornea, conjunctiva, eyelids, and tear film) and the lacrimal and accessory glands with the corresponding drainage system are essential for vision. When they fail in preserving the integrity of the ocular surface, tear film impairment and ocular surface pathologies appear as dry eyes (DEs) [1] [2] [3] [4]. This disorder usually affects elder people aged 50 years or more [5] [6] [7] particularly women, with an estimated 3.23 million American women experiencing DEs [8]. "

    ABSTRACT: The aim of this work is to investigate changes in the ocular surface (OS) and tear film (TF) by means of questionnaire-based subjective symptoms, TF break-up time, Schirmer test, and TF analysis in women working with computers and to analyze the effects of the oral supplementation with antioxidants/omega 3 fatty acids (A/ω3) in the OS outcomes. Women aged 40-65 years (n = 148) were recruited at the Administrative Offices of Valencia (Spain) and distributed into two age groups, 40-52 years (AGE1; n = 87) and 53-65 years (AGE2; n = 61), and then subdivided according to being (or not) computer users (CUG; NCUG) during the workday. Homogeneous subgroups were randomly assigned (or not) to the daily intake of three pills of A/ω3 for three months. At baseline and at the end of follow-up, personalized interviews and ocular examination were done. Reflex tear samples were collected from the inferior meniscus and processed for a multiplexed particle-based flow cytometry assay to measure proinflammatory molecules. Statistics were performed using the SPSS 15.0 program. The OS pathology was clinically evident in the AGE1-CUG (33%) versus the AGE2-CUG (64%) of women. Significantly higher interleukins-1β and -6 tear levels were found in the AGE1 versus the AGE2 women employees (P = 0.006 and P = 0.001, resp.), as well as in the CUG versus the NCUG (P = 0.001 and P = 0.000, resp.). Supplementation with A/ω3 positively influenced the OS pathology as manifested by the amelioration of the clinical signs/symptoms related to computer uses. Strategies involving a safe environment and oral micronutrient supplements may be managed within eye-care standards in older women.

    ABSTRACT: Radioactive iodine (RAI) therapy is preferred in the treatment of hyperthyroidism because of its effectiveness, noninvasiveness, and low costs. I has been detected in extrathyroidal tissues, such as in gastric mucosa, salivary glands, and lacrimal glands. To the best of our knowledge, there is no publication concerning the effects of RAI therapy for hyperthyroidism on tear production. In the present study, we evaluated whether or not the lacrimal glands are affected after RAI therapy when compared with pretreatment period. The Schirmer and tear break-up time (TBUT) tests were used to assess 32 eyes of 16 patients with conditions that were diagnosed as hyperthyroidism before and at 3 and 6 months after RAI treatment. In addition, pretreatment values of patients were compared with that of controls. It was evaluated whether or not a correlation exists between the results and the dose or iodine uptake values. There was no significant difference between pretreatment values of Schirmer and TBUT tests obtained in the patient group and those of the control group (P > 0.05). In the patient group, there was a significant difference between the posttreatment and pretreatment values (P < 0.05). There was a positive correlation between uptake values obtained at 24 hours and the values obtained by TBUT and Schirmer tests on both eyes at 3 and 6 months. At 6 months, the uptake value at 24 hours was 28.83 ± 60 for both eyes in patients with TBUT test values less than 10, whereas it was 39.25 ± 7.88 for the right eye and 39.00 ± 6.85 for the left eyes in patients with TBUT test values greater than 10. The difference was statistically significant (P < 0.05). In our study, we concluded that the decrease in mucin and aqueous production occurs due to affected lacrimal glands by RAI therapy; however, this effect is not dose dependent.

    ABSTRACT: The aim of this prospective study was to conduct histopathologic and lipidomic analyses of chalazia, in order to evaluate time-dependent changes in the lesion. Samples of surgically excised chalazia were collected over a period of 12 months from 10 patients (mean age 41 years; range, 23-58) with clinically diagnosed chalazia, who underwent scheduled surgery. The ages of chalazia varied from 2 to 28 weeks. To confirm the clinical diagnoses, the morphology of collected tissue samples was evaluated histologically after hematoxylin and eosin staining. The lipids from individual chalazia were analyzed by high-performance liquid chromatography-mass spectrometry and compared with authentic lipid standards and with the lipids of meibum collected from normal controls. We observed gradual, lesion age-dependent transformation of the lipidome of chalazia from an almost normal meibum-like composition to a very different kind of lipidome. A rapid initial increase in the free cholesterol content was followed by a gradual replacement of extremely long chain meibomian-type lipids with a mixture of shorter-chain cholesteryl esters of the C14-C18 family, triacylglycerols, ceramides, phospholipids and sphingomyelins. In addition, a rapid disappearance of wax esters and cholesteryl esters of (1-O)-acyl-omega-hydroxy fatty acids from the lipidome of aging chalazia was observed. Our results are indicative of dramatic, time-dependent changes in the lesion that may involve cholesterol as a trigger and/or a marker of subsequent degeneration of the meibomian lipidome. We hypothesize that early inhibition of these transformations may be useful in reversing the course of the disease.
