Background: Periorbital fractional CO2 laser resurfacing has been employed for facial rejuvenation purposes. However, to the best of our knowledge, no study has objectively assessed periorbital neoformation and remodeling of local cutaneous collagen, in a split-face model, from skin samples obtained during upper blepharoplasty.Objectives: The authors sought to objectively evaluate neoformation and remodeling of local cutaneous collagen after periorbital skin fractional CO2 laser resurfacing.Methods: Sixteen female patients presenting with dermatochalasis and periorbital rhytids were evaluated in a prospective and comparative study. All patients underwent unilateral periorbital fractional CO2 laser resurfacing 30 days before upper blepharoplasty. Quantification of types I and III collagen from laser-treated and untreated eyelid skin samples obtained during upper blepharoplasty was assessed with histochemical analysis (Picrosirius Red staining). Laser resurfacing treatment was applied to the untreated side immediately after the upper blepharoplasty. Two blinded, independent physicians evaluated clinical improvement in pretreatment and 1- and 6-month posttreatment digital images.Results: Histochemical analysis showed significantly higher intensity in collagen types I (treated: 158.7 ± 5.3, untreated: 139.2 ± 5.0; P < 0.0001) and III (treated: 105.1 ± 7.7, untreated: 104.1 ± 7.1; P < 0.0001) in the fractional CO2 laser treatment samples; a greater difference was detected in collagen type I. A significant improvement in periorbital rhytidosis was observed 1 month after laser resurfacing (23%); a greater improvement in the periorbital region was observed 6 months after laser resurfacing and upper blepharoplasty (43.67%).Conclusions: Periorbital fractional CO2 laser resurfacing was an effective method to improve palpebral skin, with histochemical evidence of increase in collagen types I and III.Level Of Evidence:4: [ABSTRACT FROM AUTHOR]

Sarcoidosis is a chronic multisystemic disease of unknown aetiology, characterised by non-caseating granulomas. Ocular involvement rate ranges from 30% to 60% among individuals with sarcoidosis, and can vary widely, making the diagnosis a challenge to the ophthalmologist. Cutaneous manifestations occur in about 22% of sarcoidosis cases, but eyelid involvement is rare. Eyelid swelling and nodules are the most frequent forms of eyelid involvement, but other findings have been reported. The joint analysis of clinical history, ancillary exams and compatible biopsy is needed for the diagnosis, as well as the exclusion of other possible conditions. This review aims to describe the different forms of presentations, the clinical reasoning and treatment options for ocular, eyelid and orbital sarcoidosis. [ABSTRACT FROM AUTHOR]

Background: Volume loss and muscular hyperactivity are two major components of the aging process that contribute to the formation of the folds and wrinkles. Tear trough deformity is one of the most difficult depressions to correct surgically. Objective: The authors evaluate the results of periorbital filling with hyaluronic acid (HA) in a small series of patients. Methods: Between June 2008 and December 2009, 25 patients were treated with HA to correct tear trough deformities. The HA was administered into the preperiosteal tissues with a serial puncture technique and approximately 0.1 mL was injected at each pass. Each patient's before and after photographs were reviewed by three surgeons; to objectively assess the outcomes, a quantitative scale was used to grade the pre- and postinjection results. The significance of subjective aesthetic evaluation of the photographs was evaluated with the Mann-Whitney U-test. Differences were regarded as significant if probabilities were less than 0.05. Results: The mean (SD) volume per side needed to achieve correction was 0.54 (0.27) mL on the right and 0.61 (0.30) mL on the left. Complications included some degree of bruising, erythema, and local swelling. Most patients (88%) had cosmetic improvement according to the independent evaluation. Conclusions: All patients were very satisfied with their results. During the course of the study, the authors determined that the ideal candidates for this treatment are young, with thick skin and a definite hollow. [ABSTRACT FROM AUTHOR]

Prolapsed orbital fat has rarely been described and is often confused with other conjunctival tumours, such as dermolipoma. We describe the clinical features and treatment of 15 patients with prolapsed orbital fat. We report here our experience in 15 consecutive patients who presented to the Vision Institute of Federal University of São Paulo, Brazil, between July 2004 and December 2007. Age, sex, presenting complaint, physical findings, associated local and systemic diseases, type of treatment, and complications were recorded. Ten patients were men, and ages ranged from 44–86 (mean 68). Eleven patients presented with unilateral disease. Thirteen had superotemporal prolapse, and two atypical superonasal prolapse. Two gave a history of trauma. All patients had the prolapsed fat excised for cosmetic reasons. There were no complications. Orbital fat prolapse is usually superotemporal, mainly in men, and is easily differentiated from other lesions, such as prolapsed lacrimal gland. Excision is always indicated, usually for cosmetic reasons. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this study was to analyze prospectively fifty patients submitted to lower eyelid blepharoplasty at the Federal University of São Paulo, between April 2005 and May 2007., Methods: Fifty patients were assigned to interventions into two surgical groups by using random allocation. The Surgical Group1 (control group) was composed of 25 patients who were submitted to conservatively standard fat-resection lower eyelid blepharoplasty, and routine lateral canthal support. The Surgical Group 2 (experimental group) was represented by 25 patients submitted to lower eyelid blepharoplasty with periorbital fat mobilization and arcus marginalis redrape, and routine lateral canthal support. The self-esteem of all patients was compared with those in 25 age-matched volunteers from the general population. The parameters of the Rosenberg Self-Esteem Scale were determined preoperatively and at 6-month interval postoperatively. Standardized photographs obtained before and after surgery were evaluated by three independent observers., Results: The median follow-up was 395 days (range 364 to 547 days). The mean age was 48.8 years, the population's gender was predominantly female (96%). Analysis of preoperative and postoperative photographs showed that 96% patients achieved significant improvement. Self-esteem scores improved from baseline preoperative mean levels of 5.1 (Standard Deviation = 4.1) to a mean level of 3.6 (Standard Deviation = 3.5) at 6 months post-surgery (p=0.001). No patients had orbital hematoma, blepharitis, lagophthalmos or ectropion., Conclusions: The authors concluded that both procedures are safe and effective with low complication rates, and marked improvement in self-esteem was observed in patients at 6-month follow-up.

Purpose: To analyze the ocular wavefront aberrations in patients with facial dystonia treated with botulinum toxin A., Methods: Patients with benign essential blepharospasm and hemifacial spasm in activity underwent slit lamp examination and bilateral wavefront analysis under pharmacologic mydriasis using Alcon LADARvision wavefront aberrometry system. After that, all patients were treated with botulinum toxin A injections performed by the same ophthalmologist. After one month, the wavefront analysis was performed in the same way and by the same examiner. The main outcome measure was the change in ocular wavefront aberrations. Paired T-test was used to compare pre and post-injection numeric wavefront values., Results: From a total of 11 patients enrolled in this study, 6 (54.5%) had essential blepharospasm and 5 (45.5%) had hemifacial spasm. The fellow eyes of patients with hemifacial spasm were not included, totalizing 17 eyes with spasm. Eight patients were female (72.7%) and three were male (27.3%), the male:female ratio was 1:2.6. The age ranged from 50 to 72 years old with a mean of 65.9 ± 8.2 years. The mean of high order root mean square (RMS) wavefront aberrations was 0.68 before and 0.63 one month after the treatment (p=0.01). Before the treatment, the mean of spherical aberration was 0.23 and decreased to 0.17 one month after the treatment (p=0.01). There was no significant difference in the other higher-order aberrations before and after the treatment (p>0.05)., Conclusion: The treatment with botulium toxin may decrease spherical aberrations in patients with facial dystonia.

Objective: To evaluate the results of fifty patients undergoing transcutaneous lower eyelid blepharoplasty., Methods: We conducted a prospective, randomised, controlled trial between April 2005 and May 2007. Patients were randomly divided into two groups: Group 1 consisted of 25 surgical patients undergoing traditional lower blepharoplasty and routine lateral canthopexy; Group 2 consisted of 25 patients undergoing lower blepharoplasty with fat bags transposition and routine lateral canthopexy. We used the Rosenberg Self-Esteem Scale UNIFESP / EPM to assess patients' self-esteem. We also requested the participation of three independent surgeons, who examined the pre and postoperative photographs and quantified the results with the aid of a topographic scale., Results: The mean age was 48.8 years, predominantly females (96%). The analysis of photographs showed a 96% significant improvement. Self-esteem scores improved from a preoperative average of 5.1 (SD = 4.1) to a mean of 3.6 (SD = 3.5) six months after the operation (p = 0.001)., Conclusion: Both procedures are safe and effective with low complication rates, causing improvement of self-esteem assessed six months after the operation.

Background: Volume loss and muscular hyperactivity are two major components of the aging process that contribute to the formation of the folds and wrinkles. Tear trough deformity is one of the most difficult depressions to correct surgically., Purpose: The aim of this study was to evaluate the results of ten patients submitted to periorbital filling with hyaluronic acid gel filler., Methods: Between June and August, 2008, 10 patients have had their tears troughs treated with hyaluronic acid gel filler. The filler was introduced by a serial puncture technique and approximately 0.1 ml was injected at each pass. The filler was placed in the pre-periosteal tissue. Patients photographs before and after the procedure were reviewed to assess the outcomes., Results: The mean volume per side needed to achieve correction was on the right side 0.61 ml (SD=0.25) and on the left side 0.65 ml (SD=0.26). The most common complications were bruising, erythema, local swelling, and pain at the injection site. The effect of treatment lasted up to 12 months., Conclusions: This pilot study showed that the treatment of tear trough deformity with hyaluronic acid gel filler was feasible, predictable and effective. All patients were very satisfied with their results.

Purpose: To analyze the influence of botulinum toxin on the lacrimal function of patients with facial dystonias., Methods: Patients with the diagnosis of hemifacial spasm or benign essential blepharospasm were evaluated and invited to answer the Ocular Surface Index Disease (OSID) questionnaire. All patients underwent Schirmer I and basal tests; break-up time (BUT) test and lacrimal clearance evaluation. On the following day, the patients were treated with botulinum toxin. The Ocular Surface Index Disease questionnaire and all the initial tests were reapplied 30 days after the treatment by the same examiner., Results: Twenty-six patients were enrolled in this study, 15 (57.7%) with hemifacial spasm and 11 (42.3%) with benign essential blepharospasm. The mean age of patients with hemifacial spasm was 70.9 ± 13.3 years and the male:female ratio was 1:1.5. In the group of patients with benign essential blepharospasm, the mean age was 68.9 ± 8.4 years with a female preponderance (90.0%). After the treatment, the Ocular Surface Index Disease score, Schirmer I and basal tests score decreased in both groups. The mean of Break-up time test increased significantly in both groups. The lacrimal clearance evaluation showed a greater number of eyes that achieved a complete drainage of the tears after the treatment in both groups., Conclusion: The treatment with botulinum toxin improved dry eye symptoms in patients with facial dystonia. Despite of the aqueous portion of tear have decreased, blink modifications improved the tear stability and drainage.
