RESUMO

PURPOSE: To describe surgical variations of the hatchet flap and a large series of patients in which this procedure was used for eyelid and midfacial reconstruction. METHODS: A retrospective review was performed on patients treated with a hatchet flap between March 2016 and March 2023. Patient demographics, defect characteristics, surgical techniques, and outcomes were investigated. RESULTS: The hatchet flap was used to repair 70 defects in 69 patients, aged 41.6 to 90.0 years (mean, 66.1). Defects measured 0.6 to 23.6 cm 2 (mean, 4.8) and resulted from Mohs surgery (n = 62), exenteration (n = 2), benign lesion excision (n = 3), or cicatricial ectropion/fistula repair (n = 3). The flap tail was managed with 3 techniques: V-Y plasty (n = 26), transposition (n = 34), and excision (n = 10). Ancillary procedures were often used during reconstructions (skin grafts: 29; double hatchet flap: 2; additional skin flaps: 26; tarsoconjunctival flaps: 6; and other grafts: 7). Small distal eschars healed in 7 flaps without necrosis. Four patients with subcutaneous thickening improved after steroid injections. Mild hatchet flap contracture may have contributed to postoperative cicatricial ectropion in 1 patient. There were no other flap related complications. CONCLUSIONS: In selected patients, the hatchet flap is a versatile technique to mobilize vascularized tissue into eyelid/midfacial defects resulting from the excision of lesions or treatment of cicatricial ectropion/fistulas. Individuals without laxity in the plane perpendicular to the flap base may not be good candidates for this procedure. The hatchet flap can be modified by advancing, transposing, or excising the flap tail. Reconstruction is often combined with other flaps/grafts. Few complications were associated with the hatchet flap.

RESUMO

PURPOSE: Acquired melanocytic nevi are common eyelid lesions; however, their clinical presentation is not well documented. METHODS: In this retrospective study, clinical records were reviewed in patients evaluated between 2005 and 2022. RESULTS: Eyelid margin nevi (n = 150) were more commonly excised in female (78%) and Caucasian (86%) patients. Change in appearance/size were frequent presenting complaints, and 17% experienced ocular symptoms. Referring diagnosis included other benign lesions (11.3%), and concern for malignancy (16.7%). Many individuals (38.7%) noted their lesion for ≤5 years. Nevi were distributed across the 4 margins (9% peripunctal), and 88% had a regular base. Visible pigmentation was more common in non-Caucasians (95.2%) than Caucasians (41.1%). Lashes grew through 60.7% of nevi and were often misdirected.Nevi were treated with superficial excision and cauterization. Histologic subtypes included: dermal (86.6%), compound (9.4%), blue (2.7%), junctional (0.7%), lentiginous dysplastic (0.7%). An irregular base (p=0.042) and pigmentation (p=0.056) were more common in compound than dermal nevi. Lash line quality and appearance were improved in the majority of patients returning for follow-up, although postoperative trichiasis, marginal erythema, and residual pigmentation were observed. CONCLUSIONS: Melanocytic nevi commonly involve the eyelid margins and have a variety of presentations and appearances. Existing nevi can change, and new lesions appear throughout adulthood. Stable, benign appearing nevi can be observed. Shave excision provides a diagnosis and improved appearance for symptomatic or suspicious lesions, with few serious complications. Malignant transformation is rare, although evidence for recurrence warrants further evaluation.

RESUMO

Metabolic reprogramming has been shown to occur in uveal melanoma (UM), the most common intraocular tumor in adults. Mechanisms driving metabolic reprogramming in UM are poorly understood. Elucidation of these mechanisms could inform development of new therapeutic strategies for metastatic UM, which has poor prognosis because existing therapies are ineffective. Here, we determined whether metabolic reprogramming is driven by constitutively active mutant α-subunits of the heterotrimeric G proteins Gq or G11 (Gq/11), the oncogenic drivers in ∼90% of UM patients. Using PET-computed tomography imaging, microphysiometry, and GC/MS, we found that inhibition of oncogenic Gq/11 with the small molecule FR900359 (FR) attenuated glucose uptake by UM cells in vivo and in vitro, blunted glycolysis and mitochondrial respiration in UM cell lines and tumor cells isolated from patients, and reduced levels of several glycolytic and tricarboxylic acid cycle intermediates. FR acutely inhibited glycolysis and respiration and chronically attenuated expression of genes in both metabolic processes. UM therefore differs from other melanomas that exhibit a classic Warburg effect. Metabolic reprogramming in UM cell lines and patient samples involved protein kinase C and extracellular signal-regulated protein kinase 1/2 signaling downstream of oncogenic Gq/11. Chronic administration of FR upregulated expression of genes involved in metabolite scavenging and redox homeostasis, potentially as an adaptive mechanism explaining why FR does not efficiently kill UM tumor cells or regress UM tumor xenografts. These results establish that oncogenic Gq/11 signaling is a crucial driver of metabolic reprogramming in UM and lay a foundation for studies aimed at targeting metabolic reprogramming for therapeutic development.

RESUMO

PURPOSE: The angular vein extends between the supraorbital and supratrochlear veins superiorly and the facial vein inferiorly. Rarely, this vessel can be involved by infections, vascular malformations, or benign tumors. In this study, we report both our experience and the published literature on angular vein disorders. METHODS: A retrospective study was performed on patients seen between 2008 and 2022. The medical literature was searched for reports of conditions affecting the angular vein. RESULTS: During the study period, we encountered 5 patients with angular vein disorders. Information from these patients was combined with 18 published cases. Among the 23 patients, the diagnosis was confused with lacrimal drainage abnormalities in 52%, and 57% underwent imaging. "Swelling" or a palpable, moveable mass were frequent findings. Pain or tenderness was experienced by 43.5% of patients. Five patients were observed, and 2 infections were treated with antibiotics. The remaining 16 lesions were successfully treated with excision (n = 15) or cauterization (n = 1), without complications. Final diagnosis included 14 vascular malformations (isolated varix: 7, thrombosis: 6, cavernous venous malformation: 1), 7 vascular tumors (intravenous pyogenic granulomas: 6, intravascular papillary endothelial hyperplasia: 1) and thrombophlebitis (n = 2). CONCLUSIONS: Disorders of the angular vein are uncommon and frequently misdiagnosed as lacrimal abnormalities. While these lesions can frequently be identified on clinical findings, imaging can be helpful in some cases. Patients with suspected thrombophlebitis require urgent antibiotic therapy. Minimally symptomatic angular vein lesions can be observed. Surgical excision is effective in treating the different vascular malformations and tumors affecting this structure.

RESUMO

PURPOSE: This retrospective study was performed to examine surgical results of five different techniques for lower eyelid margin reconstruction after Mohs surgery: primary closure, semicircular flap, dermal matrix graft, sliding tarsal flap, and tarsoconjunctival flap. METHODS: Medical records were reviewed in 178 patients undergoing surgery between 2005 and 2020. Outcomes were evaluated (photographic review) by three oculoplastic observers masked to procedure type, both with and without knowledge of the eyelid defect. RESULTS: All patients achieved a good-excellent functional result and 90.4% were asymptomatic after surgery. Tarsoconjunctival flaps were associated with greater need for subsequent interventions (p < .001) and anterior lamellar deformities (p < .001). Semicircular flaps had a higher incidence of lateral canthal deformity (p < .001), but less eyelash disruption than other flap/graft techniques (p < .001). Mean cosmetic ratings (defect masked) were similar for dermal matrix grafts, semicircular, and sliding tarsal flaps; with each grading higher than tarsoconjunctival flaps (p ≤ .05). Among patients with 9-15 mm wide defects, results were better for semicircular and sliding tarsalflaps, than dermal matrix grafts (p ≤ .005) and tarsoconjunctival flaps (p ≤ .02). CONCLUSIONS: All patients achieved a good-excellent functional result and 87.1% a good-excellent cosmetic result. The semicircular flap was effective for repairing medium sized wounds that could not be closed primarily, creating a continuous lash line, although with a higher incidence of lateral canthal deformities. The sliding tarsal flap was effective for shallow wounds of varying widths. The single-staged dermal matrix graft provided similar results as the tarsoconjunctival flap. Subsequent interventions were more frequent after the tarsoconjunctival flap than other methods.

RESUMO

PURPOSE: While Wendell Hughes popularized the tarsoconjunctival flap for lower eyelid reconstruction, most modern procedures are derived from the technique described by Köllner in 1911. This study reviews the history, techniques, and outcomes of a large series of patients treated with a modified Köllner flap. METHODS: In this observational cohort study, medical records and photographs were reviewed in patients undergoing surgery between 2005 and 2020. Patient demographics, complications, secondary interventions, and outcomes were evaluated. RESULTS: Marginal defect size ranged from 12 to 41 mm among the 140 study patients. Ancillary procedures included lower eyelid conjunctival flaps (n = 64) and septal orbicularis flaps (n = 68). The anterior lamella was reconstructed with skin grafts (n = 86), flaps (n = 10), or combined flaps/grafts (n = 44). Pedicle division was performed 23 to 84 days after primary repair. Subsequent interventions included steroid injection (n = 10), cryotherapy (n = 10), marginal erythema treatment (n = 9), and upper eyelid retraction repair (n = 6). Tearing (6.5%) and dryness (10%) were the most common postoperative symptoms, with most patients (78.6%) being asymptomatic. A good-excellent functional outcome was achieved in 94.3% and cosmetic outcome in 85.0% of cases. Defects <30 mm in width (P = 0.0001), defects not involving a canthus (P = 0.0158), and upper eyelid skin graft donor sites (P = 0.0001) were associated with better outcomes. CONCLUSIONS: The Köllner tarsoconjunctival flap is an effective technique to repair moderate-large lower eyelid defects, with the majority of patients achieving good-excellent cosmetic and functional outcomes. Factors associated with a poorer result include marginal eyelid defects ≥30 mm in width, defects involving a canthus, and non-upper eyelid skin graft donor sites. Most patients are asymptomatic after surgery.

RESUMO

PURPOSE: Psychogenic ptosis is a rare ophthalmic manifestation of conversion disorder. The aim of this study was to describe the clinical parameters, etiology, psychological, and clinical aspects of psychogenic ptosis. METHODS: A retrospective case series was conducted of patients with psychogenic ptosis seen between 1990 to 2020. Medical records were reviewed for patient demographics, including psychiatric history, clinical findings, diagnostic studies, treatment, and resolution rates. A literature review was performed to identify cases of psychogenic ptosis previously published between 1990 and 2020. RESULTS: Six female patients (aged 14-60 years) were diagnosed with unilateral psychogenic ptosis. Physical trauma preceded the onset of ptosis in all cases. Imaging studies had been previously obtained in all patients, none of who were correctly diagnosed at time of referral. Associated signs included concurrent brow ptosis, orbicularis oculi spasm, squint on upgaze, and variable levator function and eyelid margin measurements. Four patients had preexisting psychological conditions. Patients were primarily managed with reassurance. CONCLUSIONS: Psychogenic ptosis is an often delayed or misdiagnosed condition, resulting in unnecessary referrals and imaging. Psychogenic ptosis should be considered in patients with atypical findings of ptosis including ipsilateral brow depression, orbicularis oculi spasm, squint on upgaze, and variable eyelid measurements. A prior history of minor trauma and female sex were common in this series. Our experience suggests that psychogenic ptosis can often be treated with reassurance, leading to partial or complete resolution. Given the number of patients with comorbid psychiatric conditions, the authors recommend a low threshold for psychiatric or psychological evaluation.

RESUMO

PURPOSE: The presence of eyebrow elevation in anophthalmic patients has been used as evidence to support a proprioceptive stimulus for frontalis innervation. In this study, we examined the frequency of brow elevation before and after enucleation and reviewed additional clinical findings to determine if any were associated with eyebrow position. METHODS: A retrospective study was performed on 134 anophthalmic patients. Demographics, measurements, and photographs were reviewed. Reference photographs were used to subjectively grade brow position and sulcus depth. RESULTS: Preoperative eyebrow elevation was present in 56.2% of patients without blepharospasm from a painful eye, of who 62% had chronic visual loss. Ipsilateral ptosis (p = 0.008), deep superior sulcus (p < 0.001), and right-sided pathology (p = 0.045) were more common in patients with brow elevation. Symmetrically elevated brows were more frequent before right than left enucleation (p = 0.05). Brow position remained stable after 61.9% of procedures. While often mild, postoperative brow elevation was seen in 31.0% of patients without preoperative elevation. Deepening of the superior sulcus was more common in patients with new relative brow elevation (p = 0.031). Anophthalmic ptosis and right-left surgical side were not associated with new postoperative brow elevation. CONCLUSIONS: Eyebrow elevation was often present prior to enucleation and associated with an increased occurrence of ptosis, superior sulcus deepening, and right-sided pathology. Intact vision was not needed to maintain an elevated brow. Superior sulcus deepening, but not ptosis, was more common in patients developing new postoperative brow elevation. The findings support both proprioceptive and compensatory mechanisms for eyebrow elevation.

RESUMO

A 72-year-old man with history of chronic lymphocytic lymphoma presented with a tender, ulcerated cutaneous eyelid lesion. Excisional biopsy revealed a diagnosis of eosinophilic dermatosis of malignancy. This rare paraneoplastic eruption is associated with hematologic malignancies and characterized histopathologically by lymphocytic infiltration accompanied by numerous eosinophils. To our knowledge, eosinophilic dermatosis of malignancy involving the eyelid has not been previously reported.

RESUMO

PURPOSE: To compare the use of sizing implants versus intraoperative volume measurements for individualization of enucleation implant size, and to identify preoperative factors affecting the choice of implant. METHODS: In this retrospective observational cohort study, 2 implant sizing methods were compared using clinical records and photographs in 139 patients who underwent enucleation between 2007 and 2016. RESULTS: There was no difference in mean implant (p = 0.6562) or prosthetic (p = 0.1990) enophthalmos between the 2 methods, or when comparing patients with and without conjunctival-Tenons fibrosis. The incidence and severity of superior sulcus deformity was similar between the methods (p = 0.6394). Preoperative phthisis (p < 0.0001) and intraoperative conjunctival-Tenons fibrosis (p = 0.0010) were more common in the sizing implant group. Among all study patients, mean implant size was larger in males (21.3 mm, n = 80) than females (20.7 mm, n = 59) (p = 0.0027). Implants >20 mm were more frequently inserted in patients with a wider Hertel exophthalmometry base (80% of males >95 mm; 77% of females >97 mm). Approximately 21.0% of patients demonstrated ≥8 mm of implant enophthalmos, suggesting an undersized implant. The authors estimate that 11% of patients could have received a sphere larger than 22 mm. CONCLUSIONS: Individualization of enucleation implant size can reduce the incidence of anophthalmic socket syndrome. The empirical use of sizing implants provided similar results as intraoperative volumetric measurements, when evaluated by postoperative superior sulcus depth and prosthetic or implant enophthalmos. Preoperative exophthalmometry may facilitate selection of implant size. Preexisting conjunctival-Tenon fascial fibrosis often did not limit implant size and was not associated with a higher prevalence of wound breakdown or implant exposure.

RESUMO

PURPOSE: To describe the incidence of anophthalmic ptosis, identify clinical factors associated with its development, and evaluate the effects of enucleation on eyelid mechanics. METHODS: In this observational cohort study, measurements and photographs were reviewed in 139 patients who underwent enucleation between 2007 and 2016. Patient demographics, pre- and postoperative eyelid measurements, and exophthalmometry were used to assess the incidence of ptosis and effects of surgery on eyelid function. RESULTS: Preoperative ptosis was common and more often present in patients with enophthalmos (p = 0.0305) or reactive blepharospasm (p < 0.0001). The incidence of new-onset ptosis and improvement of preexisting ptosis following enucleation were similar (40%). Surgical repair was performed in 7% of patients with ptosis. Contralateral levator function declined with age and was positively correlated with exophthalmometry (p < 0.0001). Anophthalmic levator function was greater with increased anterior projection of the implant (p < 0.0001) and prosthesis (p < 0.0001). Patients with larger implants had improved levator function, with (p = 0.0065) and without (p = 0.0007) the prosthesis. Superior sulcus deepening was associated with decreased levator activity, but not margin-reflex distance. CONCLUSIONS: Preoperative ptosis was common, and often related to reactive blepharospasm or enophthalmos. Levator function declined with age, and correlated to greater anterior projection of the implant and prosthesis following enucleation. The surgeon can counsel patients regarding the similar likelihood (40%) of preoperative ptosis improving and new ptosis developing after enucleation. The primary factor the surgeon can modify to improve postoperative eyelid function is to maximize implant size, which is associated with greater levator activity.

RESUMO

Purpose: To report the clinical outcomes of porcine acellular dermal matrix implants sandwiched between skin and conjunctival flaps for lower eyelid reconstruction following Mohs surgery. Methods: A retrospective review was performed on patients with lower eyelid defects following Mohs surgery treated using a porcine acellular dermal matrix sandwich graft from 2013 to 2018. Patient demographics, defect size and characteristics, and collagen matrix implant dimensions were evaluated. Postoperative course and complications were also reviewed. Results: The dermal matrix sandwich graft was performed in 13 cases (12 patients). Average horizontal marginal defect width was 11.7 mm (range: 6-16 mm). Mean width of the implanted dermal matrix was 7.7 mm (range: 5-9 mm). There were no instances of infection or graft failure. The reconstructed lid had an excellent marginal contour in 11 cases (84.6%), while 2 had minimal irregularities. All patients had an excellent thickness of the reconstructed margin. One patient (7.7%) required cauterization of overgrown marginal conjunctiva after surgery. Two patients (15.4%) experienced symptomatic trichiasis, requiring electrolysis (n = 1) and epilation (n = 1). Conclusions: The dermal matrix sandwich graft is an effective method for marginal defect repair when the remaining conjunctiva and skin are sufficient to develop the necessary flaps. While the resolution of edema and erythema may take several months, an excellent final result is achieved in the majority of cases. Complications are mild, relatively uncommon, and similar to those encountered in other reconstructive procedures. This single-stage, tissue-sparing technique preserves the capability of performing future tarsoconjunctival flaps or lateral canthal procedures, should the need arise.

RESUMO

PURPOSE: This study was performed to characterize the frequency, causes, and possible risk factors of operating room (OR) fires experienced by members of the American Society of Ophthalmic Plastic and Reconstructive Surgery. METHODS: An online questionnaire was distributed to American Society of Ophthalmic Plastic and Reconstructive Surgery members, collecting data on surgical fires experienced by respondents throughout their careers. In addition, the questionnaire investigated viewpoints on OR fire safety, current practice patterns with oxygen delivery and surgical device usage, and management of patients referred after previous surgical fire exposure. RESULTS: There were 258 participants in the survey. Eighty-three surgeons (32.2%) experienced at least 1 surgical fire in their careers. Most OR fires occurred during monitored sedation cases with oxygen delivered by nasal cannula underneath drapes completely covering the head and use of a monopolar or battery-operated device. Patient hair and skin were the most common fuel sources, and most of the injuries were limited to singing of facial hair. Regarding current practice patterns, monopolar, bipolar, and battery-powered disposable devices were the most frequently used electrosurgery and electrocautery tools. Patients seen after an OR fire with another surgeon generally experienced more severe burns requiring hospitalization and subsequent procedures. CONCLUSIONS: Many oculoplastic surgeons have experienced OR fires during their careers. Certain surgical and anesthetic techniques, particularly the delivery of supplemental oxygen underneath surgical drapes and the use of monopolar electrosurgery and battery-powered electrocautery, may be associated with increased fire risk. While most of the reported OR fires did not result in significant patient injury, caution must be taken to prevent these potentially devastating events.

RESUMO

PURPOSE: The purpose of this study is to report the surgical technique and functional outcomes of the hatchet flap with transposed nasal inset for midfacial defect repairs. METHODS: An Institutional Review Board-approved, retrospective review was performed to identify patients treated using the hatchet flap with transposed nasal inset. Patient demographics, disease etiology, defect characteristics, and postoperative complications were collected from preoperative and follow-up visits. RESULTS: The hatchet flap with transposed nasal inset was performed in 5 patients between March 2016 and April 2017. Two patients developed mild transient ischemia of the nasal inset flap tip without necrosis. A suture granuloma was removed in 1 patient. No additional surgical procedures were required after the nasal inset cheek flap. CONCLUSIONS: The hatchet flap with transposed nasal inset is an effective procedure to address defects involving the upper cheek, lower eyelid, and medial canthus. Incorporation of the nasal inset helps prevent distortion of the ala and facilitates closure of the flap donor site. This technique may be employed in certain patients as an acceptable alternative to more extensive Mustardé or paramedian forehead flaps.

RESUMO

PURPOSE: To evaluate the frequency of protective lens wear by anophthalmic patients and identify factors that influence compliance. METHODS: An IRB approved descriptive retrospective chart review of patients undergoing surgery with the senior author (PLC) with an anophthalmic orbit and one remaining sighted eye. Results were tabulated and analyzed using age, indication for procedure, duration of visual symptoms, safety glasses wear, number of postoperative visits, and evidence of new trauma to the remaining eye. All patients underwent counseling on the importance of protective lens wear preoperatively and each subsequent visit. RESULTS: Etiologies for loss of the eye in the 132 study patients included trauma (33.3%), blind painful eye (33.3%), congenital disorders (14.4%), adult-onset malignancy (14.4%), and retinoblastoma (4.5%). At the final visit, protective lenses were worn in the following patterns: full-time (55.3%), frequently (11.4%), occasional (6%), and never (28.8%). The regular use of protective eyewear at last visit was more common in patients wearing glasses at presentation (79.7%), than in those who did not (32.9%; p ≤ 0.001). Increased number of office encounters correlated with more frequent use of protective eyewear (p ≤ 0.01). Patient age (p = 0.95), indication for surgery (p = 0.97), and duration of visual loss (p = 0.85) were not predictive of safety glasses wear. Three patients had evidence of subsequent ocular trauma to the remaining eye, with 2 having resultant decrease in acuity; none of these 3 patients wore safety glasses full-time. CONCLUSIONS: A significant number of anopthalmic patients were not wearing protective lenses at presentation. Overall compliance was poor; but repeated education on the importance of safety glasses appears to improve compliance. Educating referring providers and primary care physicians about the importance of early and repeated counseling is vital to increasing compliance.

RESUMO

PURPOSE: Allergic dermatitis is a common but often misdiagnosed condition that can present with a variety of findings including inflammation, eyelid malposition, and tearing. This study was performed to identify likely etiologies, along with presenting findings and treatment strategies for allergic dermatitis. METHODS: A retrospective review of clinical records was performed of patients diagnosed with allergic dermatitis in academic oculoplastics practices from 2002 to 2014. Initial consultation included review of medications and cosmeceuticals. Suspected allergens were discontinued and an ophthalmic steroid was applied. Persistent allergic dermatitis led to further medication changes or formal allergy testing in an effort to identify the causative agent. RESULTS: Sixty-one patients were identified; average age was 66 years old (range: 33-94), and 45 of the patients were women (74%). Average follow up was 7 months (range: 1-60 months). Reasons for referral included epiphora (31.2%), ectropion (24.6%), blepharitis/dermatitis (18.0%), and "droopy" eyelid (14.8%). Presenting symptoms included irritation (77.1%) and tearing (50.8%). Average duration of symptoms was 16.5 months (range: 2 days-8 years). The 3 most common etiologies were eye drops (54.2%), creams/lotions (24.6%), and cosmetics (13.1%). Rubbing/manipulation was also thought to be a significant factor in 30% of the patients. Overall, the initial treatment regimen led to at least partial resolution in 88% of patients and 66% experienced complete resolution. Patients resistant to therapy were referred for patch testing. At follow up, 98% of patients had improvement in their symptoms and 90% of patients had complete resolution of their symptoms. CONCLUSIONS: Allergic eyelid dermatitis is commonly related to eye drops and topical cosmetics or skin care products. Identification and elimination of causative agents is the mainstay of management. Topical corticosteroids often facilitate resolution of the associated inflammation. Therapy resistant patients may benefit from formal allergy testing.

RESUMO

We investigated operative course and post-operative findings of patients undergoing primary enucleation for uveal melanoma versus those requiring secondary enucleation after brachytherapy. A retrospective chart review was performed with IRB approval on patients receiving treatment for uveal melanoma. Patients with enucleation as initial treatment and patients enucleated after plaque brachytherapy were analyzed for demographic data, operative course, and post-enucleation outcome. Further cause analysis for secondary enucleations was investigated. No significant difference was seen in age, laterality, or gender between the primarily enucleated (n = 54) and secondarily enucleated (n = 34) groups. Greater difficulty with surgery was noted in 28/32 (87.5%) of secondary enucleations compared to 1/54 (1.8%) of primary enucleations (p < 0.0001). Operative time was >2 hours in 3/51 (6%) of primary enucleations (vs. 8 of 32, 25%, p = 0.02). Average implant size was similar in the 2 groups (20.6 mm), however 2/34 (6%) of secondary enucleations required dermis fat grafting. Post-enucleation anophthalmic ptosis occurred after 8/49 (16%) of primary cases (vs. 13/30, 43%, p = 0.02) and prosthetic enophthalmos after none (0%) of primary cases (vs. 5/30, 17%, p = 0.006). Class 2 gene expression profile was found in 6/8 (60%) of eyes enucleated for treatment failure. Secondary enucleation performed after plaque brachytherapy was technically more difficult, and had more anophthalmic socket and eyelid complications compared to primary enucleation for uveal melanoma. Primary enucleation may avoid additional surgery and morbidity in a subset of patients with contraindications to plaque brachytherapy.

RESUMO

Patient safety focused on a reduction in both procedural and diagnostic error is the number one concern of the United States healthcare system in the 21st century. The American Board of Ophthalmology has a longstanding interest in patient safety, and in 2015, teamed with the American Academy of Ophthalmology to convene all ophthalmology subspecialties and other prominent national organizations to address patient safety in ophthalmology. This article reviews the topic and highlights concerns for ophthalmologists.

RESUMO

PURPOSE: To report results in patients undergoing lower eyelid reconstruction following Mohs surgery using a combination of surgical techniques, the rhomboid skin flap and a sliding tarsal flap. METHODS: An IRB approved, retrospective case series of patients undergoing surgery between April 2007 and October 2014. Outcomes include establishment of a functional eyelid, quality of postoperative eyelid margin contour, and postoperative complications. RESULTS: During the study period, sliding tarsal flaps were used to repair marginal lower eyelid defects in 32 patients. Coexisting anterior lamellar defects were repaired with a modified rhomboid skin flap in 24 patients, a full thickness skin graft in 4 patients, and combined skin graft and rhomboid flaps in 4 patients. The average width of the marginal defects was 11.3 mm (range: 7-19 mm). Reconstruction resulted in a functional lower eyelid in all patients, the majority having an excellent cosmetic result (n = 20). Minimal contour abnormalities were present in 9 patients, while 3 patients developed a noticeable notch following surgery. Patients repaired with a rhomboid flap were more likely to have isolated postoperative misdirected lashes (5/24) than those repaired using a skin graft with or without a flap (0/8). CONCLUSION: Combined sliding tarsal and modified rhomboid skin flaps are an effective method of repairing superficial defects of the lower eyelid margin. This tissue-preserving technique maintains the ability to perform subsequent upper eyelid tarsoconjunctival flaps and lateral canthal procedures should a future need arise. Isolated misdirected lashes and minor contour abnormalities are the most common complications of the procedure.

RESUMO

PURPOSE: To present the various orbital soft-tissue changes that can result from the use of topical prostaglandin analogs. METHODS: A case series of patients seen in a referral oculoplastic practice with presumed prostaglandin orbitopathy. RESULTS: Thirty-five patients were found to have a variety of disorders, including deepening of the superior sulci (24/35), hypertrichosis (32/35), periocular erythema (24/35), and meibomian gland dysfunction (18/35). Marginal eyelid thinning with posterior migration of the lash line was commonly present (34/35). Increased eyelid margin tension with horizontal eyelid shortening (32/35) was often associated with lateral canthal deformity or displacement (15/35). Lower eyelid retraction (18/35) seemed to contribute to ptosis in some patients, secondary to apparent tethering at the lateral canthus. Functional conditions resulting from the above structural abnormalities included tractional ptosis (n = 4), cicatricial entropion (n = 3), cicatricial ectropion (n = 2), trichiasis (n = 2), eyelid subluxation (n = 1), and chalazia (n = 1). CONCLUSIONS: While topical prostaglandin analogs are well-tolerated by many patients with glaucoma, some individuals using these medications develop structural changes of the orbital soft tissue resulting in a variety of cosmetic and functional eyelid disorders. The eyelid margins can thin, causing posterior migration of the lashes. Increased horizontal tension of the eyelids may result in acquired blepharophimosis and upper or lower eyelid malposition. These orbital changes may be partially reversible in some patients. When possible, it is reasonable to withhold the prostaglandin and allow a period of observation before proceeding with surgical correction.
