Tratamento cirúrgico da ptose palpebral moderada e grave: análise de resultados / Surgical treatment of moderate and severe ptosis: analysis of results

Introdução: A ptose palpebral é uma afecção comum na prática clínica na qual uma perfeita avaliação torna-se mandatória. Definimos ptose quando a margem palpebral encontra-se abaixo de 2 mm da junção córneo escleral e pode ser classificada em leve, moderada e grave. Existem inúmeras técnicas de reparo e a escolha dependerá da classificação da função do músculo levantador. Métodos: Foram analisados de forma prospectiva, no período de março de 2013 a maio de 2015, quatorze (n = 14) pacientes submetidos ao tratamento cirúrgico de ptose palpebral moderada e grave (n = 21). Inúmeros fatores foram estudados, tais como grau de ptose e função do músculo elevador da pálpebra, tipo de técnica de reparo, complicações imediatas e tardias, etc. Resultados: Quatorze pacientes foram opera-dos, totalizando 21 pálpebras, sendo que, 85% foram de etiologia adquirida e 15% congênita. Com relação ao grau de ptose, 64,3% (n = 9) foram moderadas e 35,7% (n = 5) graves. No que tange à função do músculo levantador, encontramos função boa 28,5% (n = 4), moderada 28,5% (n = 4) e pobre 43% (n = 6). Em relação às com-plicações, 2 casos de hiperemia conjutival e um caso de edema. Obtivemos um alto índice de satisfação com 85,7% (n = 12), com baixas taxas de complicações. Conclusão: A ptose palpebral é uma enfermidade comum na prática clínica e exige por parte do cirurgião um perfeito conhecimento anatômico da delicada estrutura palpebral e também de sua fisiopatologia. Uma perfeita avaliação desse paciente torna-se mandatória para o emprego do tratamento mais adequado.

Introduction: Eyelid ptosis is a common condition in clinical practice for which a complete evaluation is mandatory. Ptosis is defined when the eyelid margin is 2 mm below the corneoscleral junction and can be classified as mild, moderate, and severe. There are numerous repair techniques, and the choice will depend on the classification of the function of the levator muscle. Methods: We evaluated prospectively, from March 2013 to May 2015, 14 patients who underwent surgical treatment of moderate and severe ptosis (n = 21). Several factors were studied, such as degree of ptosis and function of the eyelid levator muscle, type of repair technique, and immediate and late complications. Results: Fourteen patients (21 eyelids) underwent operation. The etiology was acquired in 85% of the cases and congenital in 15%. With respect to the degree of ptosis, 64.3% (n = 9) of the cases were moderate and 35.7% (n = 5) were severe. With respect to the muscle function of the levator, good, moderate, and poor functions were observed in 28.5% (n = 4), 28.5% (n = 4), and 43% (n = 6) of the cases, respectively. With regard to complications, 2 cases of conjunctival hyperemia and one case of edema were observed. We obtained a high satisfaction rate of 85.7% (n = 12), with low complication rates. Conclusion: Eyelid ptosis is a common presentation in clinical practice and requires on the part of the surgeon a detailed anatomical knowledge of the delicate structure of the eyelid and its pathophysiology. A complete evaluation of these patients is mandatory for the employment of the most appropriate treatment.

Investigating the Short-term Effect of Eyelid Massage on Corneal Topography.

PURPOSE: The aim of this study was to evaluate the short-term effect of eyelid massage, after the use of warm compresses, on corneal topography. METHODS: Corneal topography was evaluated on 20 subjects (mean age, 47.0 [SD ±17.3] years) using the Oculus Keratograph (Oculus, Wetzlar, Germany). Corneal eccentricity (Epsilon) was compared between topography measurements before eyelid warming (using warm compresses) (T1), after eyelid warming (T2), directly after eyelid massage (T3), and 30 minutes after eyelid massage (T4). Differences in corneal eccentricity between the enrolment measurement (T1) and consecutive measurements (T1-4) were analyzed. The contralateral eye-treated by warm compresses, but not by eyelid massage-was the control. Visual acuity (decimal), bulbar conjunctival hyperemia, and corneal staining (Cornea and Contact Lens Research Unit grading scale) were evaluated at T1 and T4 to assess clinical safety. RESULTS: No significant differences were found between consecutive eccentricity measurements overall and with the central radii (repeated-measures analysis of variance, P > .238 (massaged eyelid: Epsilon T1: 0.48 [95% confidence interval, ±0.07], T2: 0.49 [±0.05], T3: 0.49 [±0.06], T4: 0.48 [±0.06]; horizontal radii T1: 7.76 [±0.13] mm, T2: 7.74 [±0.13] mm, T3: 7.75 [±0.13] mm, T4: 7.76 [±0.13] mm; vertical radii T1: 7.56 [±0.12] mm, T2: 7.55 [±0.10] mm, T3: 7.54 [±0.10] mm, T4: 7.58 [±0.11] mm). Decimal visual acuity significantly improved at the end of the study (massaged eyelid: T1: 1.1 [±0.1]; T4: 1.3 [±0.1]; P < .032). No significant differences were detected between the consecutive evaluation of corneal staining (Wilcoxon test; P > .285). Redness was not significantly different between time points (repeated-measures analysis of variance; P = .187) in the colateral eyes. Hyperemia was significantly reduced in the massaged eyes (T1: 2.0 grade units [±0.3]; T4: 1.9 [±0.3]; P = .021). CONCLUSIONS: Eyelid warming followed by eyelid massage appears to be a safe procedure, without any clinically relevant short-term effects on the cornea.

Surgical rehabilitation of paralytic lagophthalmus by platinum chain lid loading: focusing on patient benefit and health-related quality of life.

OBJECTIVE: To evaluate patient benefit and health-related quality of life after lid loading with platinum chains in adult patients with facial palsy. STUDY DESIGN: Retrospective data collection. SETTING: Germany's largest university clinic for otorhinolaryngology, head and neck surgery. SUBJECTS AND METHODS: Thirty-five patients received validated questionnaires determining the effects of the operation on the patients' health-related quality of life (Glasgow Benefit Inventory). Scores can range from -100 (maximal adverse effect), through 0 (no effect), to 100 (maximal positive effect). Furthermore, satisfaction, complaints, and complications regarding the platinum chain implant were inquired. RESULTS: Twenty-two patients (63 %) returned a valid questionnaire. The mean follow-up time was 31.5 months. A complete coverage of the cornea was achieved in 95% of the patients after the first operation and in the remaining patients after a revision with implantation of a heavier weight. Complete symmetry to the nonaffected eye was perceived by 64%. Recurrent conjunctivitis was complained preoperatively by 18% and postoperatively only by a single patient. In 2 patients, a mild pseudoptosis was found postoperatively, and a single patient complained about blurred vision. The median total Glasgow Benefit Inventory score was 27.8 (p < 0.001). The health-related quality of life was raised in 91% of the patients; 87% were fully satisfied with the functional result, and 91% with the aesthetical result. 100% would again decide in favor of platinum chain lid loading. CONCLUSION: Platinum chain lid loading in facial palsy patients can significantly increase patients' health-related quality of life and leads to a high rate of patient satisfaction.

Scleral contact lens management of bilateral exposure and neurotrophic keratopathy.

We report an interesting case of therapeutic scleral lens management of bilateral exposure and neurotrophic keratopathy resulting from bilateral cranial nerve (CN) palsies including V, VI and VII, which caused lagophthalmos and anaesthetic corneas. Subsequent development of severe exposure keratitis with vascularisation and keratinisation of the inferior cornea was previously treated with intensive ocular lubrication, botulinum toxin injections to the upper eyelid levator muscle, temporary tarsorrhophies, bilateral amniotic membrane grafts, punctal plugs, lid taping, gold eyelid weights and soft bandage contact lenses. Corneal integrity was re-established but visual acuity remained significantly compromised by corneal vascularisation, scarring and keratin deposits. Visions on presentation to the contact lens department were R 1.90 logMAR, L 1.86 logMAR. Therapeutic, high Dk, non-fenestrated, saline filled, scleral lenses were fitted. Daily wear of these lenses have protected and hydrated the cornea, enabling corneal surface recovery whilst retaining visual and social function. The visual acuities 6 months post-scleral fitting with lenses in situ are R 0.90 logMAR and L logMAR 0.70.

External lid loading for the temporary treatment of paresis of the M. orbicularis oculi: a case report.

This clinical note re-introduces external lid loading with the help of a lead weight for the temporary treatment of lagophthalmos. Although simple and effective, the technique is rarely used. Instead of wearing a monoculus, the patient uses an individually tailored lead weight (0.8-mm thickness, 1.0-2.0g) stuck on the lid to enable its closure. Spontaneous ptosis indicates a too-heavy weight. With the musculus (M.) levator palpebrae intact, lid lifting is possible. The effect is gravity dependent; therefore, the patient has to wear the monoculus at night. To minimize the risk for lead intoxication, the surface of the weight is varnished. In the case of persistent M. orbicularis oculi paresis, internal lid loading can follow. Since 1997, a total of 152 lagophthalmos cases have been treated. All patients could close the lid immediately. Almost half the patients had to readjust the weight several times per day because of hooded eyelids. Compliance was high, and partial or complete restoration of M. orbicularis oculi function occurred in 60% of cases. In some subjects, restoration of the M. orbicularis oculi was faster than for the M. orbicularis orbis. External lid loading for the temporary treatment of lagophthalmos is simple and effective. Compared with a monoculus, vision is unimpaired and the aesthetic is more appropriate for most patients. Faster restoration of the M. orbicularis oculi hints at a potentially facilitatory effect of the weight.

[Efficient correction of posttraumatic lower lid retraction].

The paper describes pathogenesis of posttraumatic or postoperative lower lid retraction and selective approach for its correction. Temporary lid retraction caused by edema, massive hematoma or scar tissue traction should be managed conservatively by means of modern physiotherapy and cosmetic techniques. Permanent retraction requires combination of several surgical methods: free grafts and local tissue reconstruction, pedicle flap, canthopexy, canthoplasty, miopexy, lower lid support with grafts and implants. Each method addresses certain aspects of the deformation.

Lente de contato escleral na reabilitação ocular de pacientes com síndrome de Stevens-Johnson / Scleral contact lens for ocular rehabilitation in patients with Stevens-Johnson syndrome

OBJETIVO: Avaliar a eficácia do uso das lentes de contato esclerais no manejo das sequelas oculares de pacientes portadores de síndrome de Stevens-Johnson. MÉTODOS: Foram avaliados, retrospectivamente, pacientes com sequelas oculares da síndrome de Stevens-Johnson que iniciaram o uso de lente de contato escleral. Os pacientes foram submetidos a avaliação subjetiva dos sintomas através de um questionário; exame oftalmológico (medida da acuidade visual, biomicroscopia, coloração da superfície ocular com colírio de fluoresceína, teste de Schirmer). RESULTADOS: Dez olhos de 7 pacientes foram analisados. A acuidade visual dos pacientes variou de movimentos de mão a 20/25. Todos os pacientes apresentavam algum grau de opacidade corneal e simbléfaro leve. A lente de contato escleral foi adaptada com sucesso em 90 por cento dos olhos. Em todos estes casos os pacientes referiram melhora dos sintomas e da visão. Com relação aos achados biomicroscópicos observou-se melhora da hiperemia conjuntival e da ceratite, e diminuição da secreção mucosa em 90 por cento dos olhos. CONCLUSÕES: Foi possível uma adaptação bem sucedida da lente de contato escleral em grande parte dos pacientes, com melhora dos sintomas e da acuidade visual provavelmente consequentes à melhora da regularização da superfície ocular. As lentes de contato esclerais representam uma importante e acessível alternativa para a redução da limitação ocasionada pelos danos sequelares da síndrome de Stevens-Johnson.

PURPOSE: To evaluate the efficacy of scleral contact lenses use on the management of ocular sequelae from Stevens-Johnson syndrome patients. METHODS: In a retrospective study, patients who suffered sequelae of Stevens-Johnson syndrome and started the use of scleral contact lenses were followed. Patients were submitted to an evaluation of symptoms through a questionnaire; ophthalmologic exam (visual acuity measurement, biomicroscopy, ocular surface staining with fluorescein drops, Schirmer test). RESULTS: Ten eyes of seven patients were analyzed. Visual acuity varied from hand movements to 20/25. All patients presented some degree of corneal opacity and slight symblepharon. In patients whose adaptation to scleral contact lenses was successful (90 percent), they all refered improvement of symptoms and sight. As for the biomicroscopic findings it was observed an improvement of conjunctival hyperemia and keratitis and a reduction of the mucous secretion in 90 percent the cases. CONCLUSIONS: A successful adaptation to scleral contact lenses was feasible on most patients, with relief of symptoms and better visual acuity, probably due to regularization of the surface. Scleral contact lenses represent an important and accessible alternative to reduce the limitations inferred by the damages from Stevens-Johnson syndrome.

The therapeutic and optical application of a rigid gas permeable semi-limbal diameter contact lens.

PURPOSE: To evaluate the therapeutic and optical application of a semi-limbal diameter (S-LIM) rigid gas permeable (RGP) contact lens. METHOD: A retrospective non-comparative case series of 14 consecutive patients (22 eyes) who were referred to one senior optometrist for the fitting of S-LIM contact lenses at Moorfields Eye Hospital. The cases comprised of 11 patients (17 eyes) with keratoconus, 1 patient (2 eyes) post-surgical ectasia from previous LASIK, 1 (1 eye) post-graft patient, and 1 patient (2 eyes) who required corneal protection secondary to lagophthalmos. These patients had failed previously with other lens designs because of lens intolerance, unstable vision, chronic 3 and 9 o'clock corneal staining, and inadequate corneal protection for the patient with lagophthalmos. A conventional method of using diagnostic lenses with fluorescein assessment was adopted in fitting the S-LIM lenses. RESULTS: The median duration of problems encountered with previous lenses was 4 years (range 0.5-10 years). The median visual acuity with the S-LIM lens was 6/9 (range 6/5-6/24). A median of 1 diagnostic lens (range 1-3 lenses) was required to achieve a satisfactory fit. At the last recorded follow-up, 10 patients (14 eyes) had no clinically observable problem and were wearing their lenses with a median wearing time of 8h per day (range 1-18 h). The median duration of follow up was 6 months (range 2-18 months). One patient (1 eye) abandoned lens wear because of satisfactory unaided vision. CONCLUSION: The use of a semi-limbal diameter lens can be an effective modality in patients with intolerance to other lens designs. However, lens modification from the standard design and the use of ocula lubricants are often required to optimise lens fit and to enhance tolerance.

Increase of frequency in deep brain stimulation relieves apraxia of eyelid opening in patients with Parkinson's disease: case report.

OBJECTIVE: Deep brain stimulation (DBS) of the subthalamic nucleus is an effective treatment in advanced stages of Parkinson's disease. However, approximately 5% of patients might develop apraxia of eyelid opening after DBS of the subthalamic nucleus. We provide data on a new noninvasive treatment approach to this adverse event. CLINICAL PRESENTATION: We report 2 patients who acquired apraxia of eyelid opening after DBS. This adverse event was relieved by changing the stimulation parameters. INTERVENTION: The stimulation frequency was increased from 100 Hz to 180 Hz in 1 patient and 160 Hz in the other, resulting in a total relief of symptoms. CONCLUSION: Increasing stimulation frequency may be beneficial in apraxia of eyelid opening acquired after DBS of the subthalamic nucleus.

Customized gold weight eyelid implantation in paralytic lagophthalmos.

UNLABELLED: Gold eyelid implantation is widely considered the procedure of choice to reanimate the upper eyelid in paralytic lagophthalmos. Commercially supplied implants are not readily available in all places and are sometimes cumbersome to import. OBJECTIVE: We aimed to devise a method whereby every surgeon performing gold eyelid implantation could have easy and quick access to the implant. Furthermore, we aimed to develop a means of creating an implant of the exact weight required for complete eyelid closure. STUDY DESIGN AND SETTING: A prospective study was performed from 1997 to 2005 in a tertiary research hospital, involving 50 subjects requiring gold upper eyelid implantation and using the technique in question. RESULTS: Only patients with a minimum follow up of one year were included in the study group. Symptoms improved in 96 per cent of subjects, who were able to dispense with eyedrops and eye ointments. Visual acuity improved in 92 per cent of patients. There were two extrusions amongst the early cases. CONCLUSION AND SIGNIFICANCE: Customized gold eyelid implantation offers an alternative in regions where commercial implants are not easily obtained.

Electrical stimulation of the paralyzed orbicularis oculi in rabbit.

Dysfunction of the seventh cranial nerve often results in facial paralysis and loss of the ability to blink the eye, which can lead to corneal scarring, diminished vision, and potential loss of the eye. This study investigated the potential of electrical stimulation of the orbicularis oculi muscle as a means of restoring blink function. An animal model of orbicularis paralysis was created by sectioning the seventh cranial nerve in rabbit. Twenty paralyzed and five normal rabbits were acutely implanted with a subcutaneous stimulating electrode near the margin of the upper eyelid. Biphasic current controlled stimulation pulses were delivered between implanted contacts at the medial and lateral edges of the eyelid. Strength-duration curves for lid twitch threshold were generated, and quantitative measurements of lid closure were made for systematically varied parameters including pulse amplitude, pulse width, number of pulses delivered, and duration of paralysis prior to stimulation. Normal rabbits achieved a greater degree of lid closure due to electrical stimulation than rabbits that had been surgically paralyzed. Of rabbits that had been paralyzed, those demonstrating evidence of at least partial reinnervation achieved a greater degree of lid closure than those demonstrating persistent denervation. Trains of 10 ms biphasic pulses delivered at 50 Hz were found to be the most effective means of eliciting lid closure for the range of parameters tested.

[Histopathology after implantation of lid weights]. / Histopathologie nach Implantation von Lidgewichten.

BACKGROUND: Various implants are used to treat lagophthalmos in facial paralysis. The implantation of gold or platinum eyelid weights (lid loading) is being used increasingly. Histological changes have not yet been systematically examined in the implant capsule during explantation of the eyelid weight. MATERIAL AND METHODS: Of 26 explanted implants, 18 implants in 17 patients were followed-up using light microscopy from 1997 to 2004. We semi-quantitatively evaluated the density of the inflammatory infiltrate and recorded the occurrence of foreign bodies in the tissue. The inflammatory infiltrate was also immunohistochemically examined to characterize cellular composition. RESULTS: In the semi-quantitative examination of inflammatory infiltration density, 60% of the gold implants showed a moderately dense or dense inflammatory infiltrate, while there was moderately dense infiltration in only 12.5% of the platinum implants. The immunohistochemical examination revealed a mixed lymphocytic inflammatory infiltrate which tended to a preponderance of B lymphocytes (humoral response). This is typical of unspecific chronic inflammation. CONCLUSIONS: Both gold and platinum are suitable for treating lagophthalmos, however, platinum has a higher density and better biocompatibility than gold.

Early versus late gold weight implantation for rehabilitation of the paralyzed eyelid.

OBJECTIVES/HYPOTHESIS: The purpose of this study is to evaluate the outcomes and complications associated with early gold weight implantation for management of the paralyzed eyelid. STUDY DESIGN: A retrospective review of clinical charts was conducted to analyze results and complications in patients who underwent gold weight implantation within 30 days of onset of facial nerve paralysis and to compare these outcomes with those of patients who received gold weights after a traditional waiting period. METHODS: The charts of 67 patients who underwent gold weight implantation during the time period of this study were reviewed. Patients were categorized into "early" or "late" groups based on whether gold weights were implanted before or after 30 days following onset of facial nerve paralysis. Etiology of facial nerve paralysis, degree of paralysis, timing of surgery, and outcomes of the procedure, including degree of lid closure and complication rates, were compared between the two groups. RESULTS: Of the 67 patients, 49.3% underwent gold weight implantation within 30 days of onset of paralysis and 50.7% received gold weights after 30 days. A total of 89.2% of all patients who underwent implantation in this study achieved satisfactory lid closure after the initial procedure. Both early and late implantation groups had statistically similar lid closure and complication rates. CONCLUSIONS: Implantation of gold weights within 30 days of paralysis is as effective for the management of paralytic lagophthalmos as delayed implantation and is not associated with higher complication rates. Early implantation of gold weights should be considered in all patients with paralytic lagophthalmos.

Temporal galeal fascia cover of custom-made gold lid weights for correction of paralytic lagophthalmos: long-term evaluation of an improved technique.

BACKGROUND: Chronic paralytic lagophthalmos is a condition that is often conservatively treated with ophthalmic ointments and eye drops, but usually requires definitive surgical correction. PURPOSE: An effective modification of the gold lid loading technique is described, which we have found to be the simplest and most reliable method for lid reanimation. MATERIAL: After empiric evaluations with lead fisherman's weights 'glued' to the eyelid, a custom-made gold lid weight is made by a jeweller on the basis of the tarsal dimensions of the individual patient, and then sutured to the tarsus under local anaesthesia and covered with a fine sheet of temporal galea. Other ancillary procedures (lower lid suspension, lateral tarsal strip, lateral tarsoplasty) are added as required. METHODS: Between 1990 and 1996, 27 patients underwent this type of surgery, of whom 24 were re-evaluated after a mean follow-up period of 73.2 months (range 36-96 months), 14 of these for a minimum of 5 years. RESULTS: None of the gold weights was extruded, all 24 patients experienced marked improvement of their dry-eye symptoms and expressed a high degree of satisfaction. Six patients underwent further minor surgery (lateral McLaughlin tarsorrhaphy) in order to improve relative underaction. Two patients had ptosis (less than 2 mm of asymmetry) of the affected side but refused further correction. CONCLUSION: The use of custom-made gold lid weights and a protective galeal layer is a simple, reliable and successful means for permanently rehabilitating paralysed eyelids.

[Rehabilitation of the eye in patients with facial paralyses: indications and results of gold weight implantation]. / Rehabilitation des Auges bei Patienten mit Fazialisparalysen: Indikationen und Resultate von Gold-Gewicht-Implantaten.

BACKGROUND: Upper-lid gold weight insertions in patients with long-standing facial palsy allow closure of the eye through an increased gravitational pull on the relaxed eyelid and complete opening without restriction of the peripheral visual field. MATERIALS AND METHODS: Between 1990 and 1995, 45 patients underwent eyelid rehabilitation for facial nerve paralysis at the New York Eye & Ear Infirmary. Their charts and outcomes were reviewed retrospectively. Twelve patients were followed prospectively at the University Hospital Zurich since December 1995. RESULTS: One gold weight extruded twice in one patient. Delayed infections 1-3 months after surgery occurred in 6.6% and could be treated without removal of the gold weight. Tarsorrhaphies were necessary in 11%. Overall one third of all patients had their gold weight removed during this 5-year observation period. They all had return of their facial movements and did not require further lid loading. All prospectively evaluated patients had a marked improvement of their dry eye symptoms and a better quality of life. CONCLUSION: The analysis of 57 patients indicates, that gold weight insertions are a simple, reliable, reversible and successful technique for early rehabilitation of the paralyzed eyelid, often combined with lower lid shortening procedures. We favor early implantation in patients with severe facial nerve injury, concomitant Vth nerve palsy, inadequate patient compliance, in patients with one eye only or with disturbing dry eye symptoms.

[New methods for the treatment of loss of eyelid closure in reversible facial paralysis]. / Neue Methoden zur Behandlung des fehlenden Lidschlusses bei reversibler Fazialisparese.

BACKGROUND: For prophylaxis or therapy of lagophthalmic keratopathy ointment application or hour glass dressing is indicated. The hour glass dressing has the disadvantage of a continuous visual impairment by steaming up of the moisture chamber. The main problem for the patients is the strong subjective feeling of physical handicap. A therapeutic alternative is the gravity dependent lidloading, which is known as gold implantation in cases of irreversible lagophthalmos. METHODS AND PATIENTS: By lead weights of 0.8 to 2.0 g, which are fixed to the upper lid by a foil glueing on both sides (Tesafix) or in allergic patients by an adhesive layer, well tolerated by the skin (Combihesive), the lidclosure can become restored without impairment of lid-opening. In a controlled study the described method was first tested on 10 normal persons and than applied to 22 patients with lagophthalmos. Meanwhile the new method was applied to 32 further patients. RESULTS: The "liddynamic" procedure is effective and well tolerated; it is more accepted, especially during the day, because of better visual function and better cosmetics. The hour glass dressing, is still of importance in serious cases of keratopathy during the night. CONCLUSION: "lidloading" with lead weights, which are glued by an adhesive layer to the upper lid, can be recommended as a new method in cases of reversible lagophthalmos or as a preparing step before a gold implantation.

Treatment of lagophthalmos of the eye with a custom prosthesis.

Inability to close the eyelids (lagophthalmos) is a major problem for patients with facial paralysis. Various treatment modalities and combinations can be used to restore function and esthetics. Lid loading is an effective method of treatment and can be further enhanced by custom fabrication of the prosthesis. The dentist functions as an integral part of the treatment team, working with the plastic surgeon and ophthalmologist to achieve the most functional and esthetic result.
