Unravelling the Complex Anatomy of the Tear Trough and Lower Eyelid Folds: A Review of Cadaveric Studies in the Literature.

The lower eyelid tear trough deformity is a common cosmetic concern which is the result of multiple anatomic changes in the lower eyelid, usually resulting from age. A sound understanding of the underlying anatomy is vital to inform surgeons about the ideal treatment options for rejuvenation of this region and to minimize the risk of complications. Cadaveric studies provide unique insight into underlying anatomic changes.

Videographic Analysis of Blink Dynamics following Upper Eyelid Blepharoplasty and Its Association with Dry Eye.

Unlabelled: This study was undertaken to characterize the effects of upper eyelid blepharoplasty on blink dynamics and to evaluate the hypothesis that changes in blink dynamics following blepharoplasty are associated with postoperative dry eye.

Methods: The voluntary blink of 14 eyes of 7 patients with dermatochalasis undergoing upper eyelid blepharoplasty was recorded with a high-speed camera preoperatively and 6-8 months postoperatively, alongside a group of 11 controls. The images were analyzed for palpebral aperture, blink duration, and maximum velocity during opening and closing phases.

Does strabismus surgery improve quality and mood, and what factors influence this?

AimsTo establish the impact of adult strabismus surgery on clinical and psychosocial well-being and determine who experiences the greatest benefit from surgery and how one could intervene to improve quality of life post-surgery.MethodsA longitudinal study, with measurements taken pre-surgery and at 3 and 6 months post-surgery. All participants completed the AS-20 a disease specific quality of life scale, along with measures of mood, strabismus and appearance-related beliefs and cognitions and perceived social support.

Analysis of blink dynamics in patients with blepharoptosis.

Owing to the rapid movements of the human upper eyelid, a high-speed camera was used to record and characterize voluntary blinking and the blink dynamics of blepharoptosis patients were compared to a control group. Twenty-six blepharoptosis patients prior to surgery and 45 control subjects were studied and the vertical height of the palpebral aperture (PA) was measured manually at 2 ms intervals during each blink cycle. The PA and blinking speed were plotted with respect to time and a predictive model was generated.

The Mechanics of Brow-Suspension Ptosis Repair: A Comparative Study of Fox Pentagon and Crawford Triangle Techniques.

Purpose: To perform quantitative analysis of the most commonly used brow-suspension configurations.

Methods: The inflection positions for Fox pentagon and Crawford triangle configurations were marked on 49 healthy volunteers (male and female) and photographs taken in 3 states: "normal," "closed," and "raised." The skin marks were measured vectorially with respect to the medial canthus, and displacement changes were evaluated for "normal-to-closed" ("blinking") and from "closed-to-raised" ("eye-opening") states.

What do patients with strabismus expect post surgery? The development and validation of a questionnaire.

Aims: To develop and validate a short questionnaire to assess patients' expectations about outcomes post strabismus surgery.

Methods: Questionnaire items were extracted from previous literature and reviewed by a multidisciplinary team. A cross-sectional study was then undertaken with 220 adult patients due to undergo strabismus surgery.

Microstructure and mechanical properties of synthetic brow-suspension materials.

Levator palpebrae superioris (LPS) is a muscle responsible for lifting the upper eyelid and its malfunction leads to a condition called "ptosis", resulting in disfigurement and visual impairment. Severe ptosis is generally treated with "brow-suspension" surgery, whereby the eyelid is cross-connected to the mobile tissues above the eyebrow using a cord-like material, either natural (e.g.

A review of the medical treatment of pediatric glaucomas at Moorfields Eye Hospital.

Purpose: To report on the medical treatments used for pediatric glaucomas.

Patients And Methods: A retrospective case series consisting of reviewing the medical notes of pediatric glaucoma patients under the care of the Glaucoma Service at Moorfields Eye Hospital NHS Foundation Trust. The medical notes of 200 patients were selected.
