to present in contact lens wearers than non-contact lens wearers (P = 0.03). Decreased FTBUT was associated with increased LWE length and width (P < 0.005 and P = 0.01, respectively), although only a small effect size was noted. Presence of LIPCOF was linked with a 0.25-grade increase in LWE width (P = 0.01). Only LWE width was associated with greater symptoms in contact lens wearers.LWE was associated with decreased tear-film stability, contact lens wear, lid anatomy, and LIPCOF.

There has been interest in determining whether lid wiper epitheliopathy (LWE) plays a key role in causing ocular discomfort. Conflicting reports have made it difficult to discern whether LWE is more prevalent in certain populations, what characteristics are associated with its severity, and what its role is in symptomology. This cross-sectional study on a large and diverse population attempts to answer

3. Evidence-Based Medicine: A Graded Approach to Lower Lid Blepharoplasty. (PubMed)

Evidence-Based Medicine: A Graded Approach to Lower Lid Blepharoplasty. After studying this article, the participant should be able to: 1. Define the anatomy of the lower eyelid tarsoligamentous framework and the related periorbital retaining ligaments, and cite their surgical relevance. 2. Perform a systematic functional and aesthetic evaluation of the lower eyelid focusing on the lid-cheek junction, and clinical tests that predict the need for lateral canthal tightening. 3. Enumerate (...) the different approaches to lower eyelid rejuvenation and discuss their merits/limitations. 4. Describe surgical strategies to blend the lid-cheek junction and tighten the lateral canthal retinaculum.Modern lower lid blepharoplasty requires a thorough understanding of periorbital anatomy, age-related changes of the lid-cheek junction, and the variables controlling lower lid tone and position. The surgical strategies are best used in a graded fashion. The patient with isolated lower lid bags may be treated

4. The Six-Step Lower Blepharoplasty: Using Fractionated Fat to Enhance Blending of the Lid-Cheek Junction. (PubMed)

The Six-Step Lower Blepharoplasty: Using Fractionated Fat to Enhance Blending of the Lid-Cheek Junction. Lower lid blepharoplasty is one of the most complex procedures performed by plastic surgeons and may cause significant long-term sequelae, including inadequate aesthetic outcomes if not performed with a thorough understanding of anatomy and proper technique. The authors' practice is consistently evolving to deliver the highest quality results for their patients. The purpose of this article (...) is to introduce an additional sixth step to the lower lid blepharoplasty procedure involving the targeted injection of fractionated fat to better blend the lid-cheek junction. This added step will enhance overall facial rejuvenation, is reproducible, and will provide patients with exceptional outcomes.

5. Impression Cytology of the Lid Wiper Area (PubMed)

Impression Cytology of the Lid Wiper Area Few reports on the cellular anatomy of the lid wiper (LW) area of the inner eyelid exist and only one report makes use of cytological methods. The optimization of a method of collecting, staining and imaging cells from the LW region using impression cytology (IC) is described in this study. Cells are collected from the inner surface of the upper eyelid of human subjects using hydrophilic polytetrafluoroethylene (PTFE) membranes, and stained (...) morphologies and metabolic activity in the LW area. To our knowledge, this is the first time this selection of fluorescent dyes was used to image LW IC membranes. This protocol will be effective in future studies to reveal undocumented details of the LW area, such as assessing cellular particularities of contact lens wearers or patients with dry eye or lid wiper epitheliopathy.

6. Usefulness of Titanized Polypropylene Mesh and an Anchor System for Correction of Lower Lid Retraction (PubMed)

Usefulness of Titanized Polypropylene Mesh and an Anchor System for Correction of Lower Lid Retraction Because of the lower eyelid's free edge anatomy, it is difficult to preserve its contours after reconstruction. We recently attempted a new operative procedure to treat 2 cases of lower lid retraction by using a titanized polypropylene mesh and an anchor system. As the lower lid skin is elevated laterally in an oblique upward direction, the location of the mesh insertion is decided

9. Modified transconjunctival lower lid approach for orbital fractures in East Asian patients: the lateral paracanthal incision revisited. (PubMed)

Modified transconjunctival lower lid approach for orbital fractures in East Asian patients: the lateral paracanthal incision revisited. Optimal repair of an orbital fracture requires adequate exposure into the orbit. The transconjunctival approach with lateral canthotomy is a valid option in East Asian patients, who are especially sensitive to the appearance of an external skin scar, although one must also recognize the potential complications associated with eyelid aperture mechanics (...) is an alternative approach to the orbital wall. The decoupling of the lower eyelid through the lateral portion of the tarsal plate provides excellent exposure of the orbital floor and provides a reliable and consistent landmark by which the anatomy of the eyelid can be restored. The aesthetic and functional outcomes are excellent.Therapeutic, IV.

Upper eyelid overhang and the resultant tired facies have led patients to seek correction for the last century. Understanding the dynamic anatomy of the upper eyelid (...) heaviness of the upper lid often present in those with no fold. Previous Next: Etiology The etiology of upper eyelid deformity is related intimately to the anatomy of the area (for more information, see ). Weakening of connective tissues, loss of skin elasticity, and the effects of gravity over time all contribute to the development of dermachalasis. Loss or lowering of the palpebral crease is caused by failure of the skin-adhering bands of the levator aponeurosis to cause folding of the skin
