Melanocytoma of the eyelid: Case report and introduction of new nomenclature.

Purpose: The term melanocytoma was recently proposed for intermediate-stage melanocytic lesions with specific histopathologic and molecular genetic features. Prior studies have demonstrated a heightened potential for these intermediate lesions to spread to regional lymph nodes, with decreased likelihood for distant spread, when compared to melanomas. Observations: Herein we present a case of a 28-year-old male who presented with a recurrent right lower eyelid margin combined cutaneous and palpebral conjunctival pigmented lesion, ultimately classified as a melanocytoma, to highlight this new nomenclature, characteristic histopathologic and genetic findings, and prognostic implications. Conclusions: Ophthalmologists should be aware of this new cutaneous histopathologic classification system and apply to the periorbital region to improve melanocytic lesion management and surveillance.

Delayed orbital floor implant complications: Case report and review of the literature.

Purpose: Foreign body reaction to non-absorbable alloplastic orbital implants utilized for bony reconstruction are infrequently documented in the literature. We present the workup and surgical management of a giant cystic mass encapsulating a patient's alloplastic orbital implant, which was ultimately deemed to be a result of foreign body reaction. Observations: A 41-year-old male patient with distant history of a right orbital floor fracture had undergone repair with the placement of a nylon foil implant. The patient presented twenty years later with progressive ipsilateral globe proptosis and was found to have a giant inferior orbital cyst. Surgical exploration and removal of the implant and capsule were performed. Histopathology confirmed a delayed foreign body reaction around the patient's alloplastic implant. Conclusions: Alloplastic implants may result foreign body reaction and cyst encapsulation as a delayed complication.

Post-Operative Endonasal Debridement May Improve Outcomes of Endoscopic Dacryocystorhinostomy.

Background: Endoscopic dacryocystorhinostomy (endoDCR) has proven to be an effective minimally invasive surgical procedure for treatment of nasolacrimal duct obstruction. Post-surgical endonasal debridement has not yet been independently assessed for its impact on functional success. Methods: A retrospective review was performed of all patients who underwent endoDCR by an experienced oculofacial plastic surgeon over 7 years (2012-2019). Post-operative intranasal debridement was not routinely performed from March 2012 to February 2016. From March 2016 to June 2019, all patients underwent routine ipsilateral intranasal debridement at post-operative week 2. Surgical success was determined based upon subjective assessment of epiphora resolution at the patient's final post-operative visit. Results: A total of 69 patients (88 surgeries) were included. Thirty-five patients had standard post-operative follow-up without debridement, whereas 34 underwent endonasal debridement at post-operative week 2. Demographics and follow-up were similar between the 2 groups. Functional success was achieved in 84.1% of patients without debridement, and in 97.7% with debridement (P = .058). Conclusion: This review demonstrates a trend toward improvement in the rate of surgical success of endoDCR when routine endonasal debridement was instituted 2 weeks following surgery. We believe that removal of nasal crusts, clots, and residual absorbable gelatin sponge at the osteotomy site improves tear outflow and reduces cicatricial healing enhancing patency of the surgically derived lacrimal-nasal fistula. We advocate for postoperative debridement in the perioperative management of endoDCR patients to optimize successful outcomes.

Fungal Endophthalmitis Masquerading as Sympathetic Ophthalmia.

PURPOSE: To describe the ocular pathology of a patient with fungal endophthalmitis with features mimicking sympathetic ophthalmia. METHODS: Review of medical records and histopathology of a single patient. RESULTS: A 72-year-old male who sustained penetrating injury to the left eye with an agave plant presented to our clinic 16 months after the initial injury. Prior to presentation, the patient had developed endophthalmitis and had undergone anterior chamber washout, vitrectomy, and intravitreal steroids, antibiotics, antifungals, and anti-vascular endothelial growth factor (VEGF) therapy. At presentation, the patient had a blind, painful eye and subsequently underwent enucleation. Histopathology demonstrated granulomatous inflammation with multinucleated giant cells in the iris and Dalen Fuchs nodules with CD68 positive epithelioid histiocytes associated with the retinal pigment epithelium (RPE) sparing the choriocapillaris. These findings were initially attributed to sympathetic ophthalmia. The fellow eye did not have any signs of inflammation, and additional fungal PAS stains were positive for filamentous fungal elements, leading to a diagnosis of fungal endophthalmitis. CONCLUSIONS: Fungal endophthalmitis may develop histopathologic features that are similar to those seen in sympathetic ophthalmia. Recognition of the overlap between the histopathologic features of these diseases may reduce the possibility of misdiagnosis and unnecessary treatment of the fellow eye.

Giant Lacrimal Gland Cyst in a Pediatric Patient: Case Report and Review of the Literature.

Lacrimal gland cysts are rare clinical entities in the pediatric population. Herein is described a 6-year-old male patient presenting with progressive left upper lid ptosis, found to have a large ipsilateral superotemporal orbital mass. Diagnosis of a giant lacrimal gland cyst was confirmed excisional biopsy. Despite the resolution of mechanical blepharoptosis, the patient maintained visual acuity limitation due to suspected deprivation amblyopia. The pathophysiology and clinical manifestations of lacrimal gland cysts in the pediatric population are reviewed to emphasize the importance of expedited identification and management in this patient cohort.

Cutaneous angiosarcoma presenting as bilateral periorbital edema.

A 66-year-old man presented with chronic bilateral periorbital edema with associated yellowish hue, scattered violaceous smooth macules and contracture of the forehead. He had undergone dental surgery 3 months prior to symptom onset. Laboratory workup for common causes of eyelid edema was unremarkable and MRI of the orbits was unrevealing. The patient did not respond to oral corticosteroids or antibiotics. Punch biopsies were obtained which revealed atypical lymphatic endothelial cells consistent with a diagnosis of cutaneous angiosarcoma.The patient was deemed not to be a surgical candidate and underwent 3 cycles of immunotherapy with limited response. He declined further treatment and transitioned to hospice care. Although cutaneous angiosarcoma uncommonly involves the periorbital region, it should be considered in the differential diagnosis of eyelid edema as early recognition and treatment are critical to prevent rapid intradermal spread and metastases.

5-Fluorouracil With Microneedling Modulates Wound Healing in a Murine Model: An Immunohistochemical Analysis of Mechanism and Dose Efficacy.

PURPOSE: The purpose of this study is to assess the dose-dependent immunohistopathological effects of intradermal microneedle-delivered 5-fluorouracil (5-FU) for postincisional wound healing in a murine model. METHODS: A prospective experimental study was performed. Twelve hairless mice were randomized into 4 treatment groups for postincisional wound treatment: microneedling with topical saline, or microneeding with topically-applied 5-FU at concentrations of 25 mg/ml, 50 mg/ml, or 100 mg/ml. Two surgical wounds were created on each animal. Combination wound treatments were performed on postoperative days 14 and 28, and cutaneous biopsies were obtained on day 56. Specimens were analyzed by a dermatopathologist, blinded to the treatment group, for collagen thickness, lymphocytic infiltration, histiocytic response, sub-epidermal basement membrane zone thickness, and myofibroblast density. RESULTS: Histopathologic evaluation showed increased collagen thickness, lymphocyte infiltration, and granuloma density in the groups undergoing microneedling treatment with 5-FU, compared to saline. Immunohistochemical analysis revealed a trend toward thicker basement membranes with higher concentrations of 5-FU used, reaching statistical significance between controls and those treated with 100 mg/ml 5-FU ( p = 0.0493). A trend toward decreasing myofibroblast density with increasing doses of 5-FU was noted. No postincisional or treatment complications were observed. CONCLUSIONS: Our results demonstrate that microneedling is an effective topical subepithelial drug delivery system, and further suggest a beneficial dose-dependent immunomodulatory effect of 5-FU on intermediate wound healing when used in combination with microneedling. We recommend a 5-FU dose at the mid-range 50 mg/ml concentration to simultaneously maximize efficacy and minimize complication risk.

Oculoplastic fellow education during the COVID-19 crisis.

PURPOSE: In March 2020, the American Society of Ophthalmic Plastic and Reconstructive Surgery (ASOPRS) advised the suspension of all non-emergent oculofacial patient care, imparting unprecedented interruptions in fellowship training. METHODS: ASOPRS fellows and program directors were asked to complete an anonymous survey regarding their perceived impact of the COVID-19 crisis. RESULTS: Forty ASOPRS fellows (70.2%) participated, including 20 first-year and 20 second-year trainees, from all country regions. During the social distancing restrictions, 100% of fellows continued to participate in surgical procedures, including orbital biopsy (77.5%), abscess drainage (55.0%), fracture repair (45.6%), eyelid lesion excision (70.0%) and temporal artery biopsy (57.5%). ASOPRS fellows evaluated patients, including in emergency room (84.6%) and inpatient hospital (76.9%) settings, wearing surgical (85.0%) or N-95 (40.0%) masks, gloves (80.0%) and eye protection (62.5%).Most ASOPRS fellows (87.5%) participated in virtual interinstitutional education sessions and indicated a desire to continue this curriculum. Fellows also used available time for research (85.0%), independent study (77.5%), personal health (70.0%) and social interaction (60.0%).ASOPRS fellows reported COVID-19 restrictions to have a mild (72.5%) to moderate (27.5%) impact on their overall training, and most (75.0%) felt their surgical confidence to decline. Fellowship program directors also asserted a mild (72.2%), moderate (19.4%) or significant (5.6%) impact on subspecialty training, and 94.4% predict adverse effects on graduation case logs. CONCLUSIONS: During the COVID-19 restrictions most ASOPRS fellows participated in emergent clinical activities and novel telemedicine curriculum. Most fellows and program directors expressed concern regarding a negative impact on overall subspecialty education and surgical confidence.

Autologous Fat Transfer Harvest-site Complications: Incidence, Risk Factors, and Management.

PURPOSE: Autologous fat transfer is an effective tool for volume restoration to the aging face. Although numerous reports exist regarding injection site complications, there is limited data on donor-site morbidity in the cosmetic surgery literature. METHODS: This study is a large-scale retrospective review to determine incidence of fat harvest-site complications, identify risk factors, and describe management strategies. Records of all patients who underwent autologous fat harvesting and facial grafting at a single oculofacial plastic surgery practice from 2010 to 2019 were reviewed. Patient demographics and clinical data were collected and assessed. A statistical analysis was performed using a two-tailed T-test with p values of <0.05 considered significant. RESULTS: Four-hundred sixteen patients were followed for an average of 6.2 months postoperatively. There was an overall 5.5% harvest-site complication rate. There was no correlation of harvest-site complications with gender (p = 0.249) or age (p = 0.881). Harvest location did not significantly correlate with complication rate. The most common complications were contour irregularities, prolonged induration, and prolonged erythema. Low body mass index was associated with higher complication rate (p = 0.003), even when excluding those patients with contour irregularities (p = 0.001). Various treatment modalities were used to manage donor-site morbidity with consistent improvement. CONCLUSIONS: Autologous fat transfer used for facial volume augmentation has low donor-site morbidity. Minor harvest-site complications occur more commonly in patients with low body mass index, irrespective of age, gender, or fat source.

Simultaneous presentation of orbital mantle cell lymphoma and endocrine mucin-producing sweat gland carcinoma.

Mantle cell lymphoma is a rare malignancy to present in the orbit, comprising only 1-5% adnexal lymphomas. Endocrine mucin-producing sweat gland carcinoma (EMPSGC) is an equally uncommon adnexal tumor of sweat gland origin that may present on the eyelid. Herein we present a case of a 77-year old man with no previous cancer history who presented with painless progressive left globe proptosis and an enlarging left upper lid margin lesion, ultimately determined upon biopsy to be simultaneous orbital mantle cell lymphoma with systemic involvement and isolated eyelid EMPSGC. The pathogenesis, clinical manifestation, and management for each rare disease entity are reviewed and concept of collision tumors is discussed.

Consideration of Nasal Contour in Endoscopic Forehead Rejuvenation.

Purpose: Preliminary studies have suggested an improvement in nasal aesthetics after endoscopic forehead lifting. We aimed to assess subjective and objective changes in nasal contour after minimally invasive forehead rejuvenation. Methods: We performed a retrospective review of patients who underwent endoscopic forehead lifting by four surgeons at a single surgery center from 2004 to 2018. All patients had subperiosteal blunt release of soft tissues overlying the radix. Changes in nasal contour were assessed on pre- and postoperative patient photos by four independent judges using the Global Aesthetic Improvement Scale. Objective changes in nasal length and length-to-base ratio were measured on patient photographs using ImageJ software. Measurements were further compared by demographic variables of age and gender. Results: In total, 326 patients met inclusion criteria. Summative judging results revealed 79.4% of patients with clinical improvement in nasal contour (11.1% very much improved, 25.6% much improved, and 42.6% improved), 20.1% with no change and 0.6% with worsening. There was a statistically significant increase in average nasal length (2.17 mm, p < 0.0001) and length-to-base ratio (0.03, p < 0.0001) postoperatively. Stratification of patients by age and gender did not reveal a significant difference in degree of nasal proportion change. Conclusions: There is a noteworthy subjective and quantitative improvement in nasal contour and length after endoscopic forehead lifting. This change restores ideal facial proportions and may serve as a useful counseling point when offering this surgery to patients.

Wound Dehiscence Following Upper Blepharoplasty: A Review of 2,376 Cases.

PURPOSE: There have been limited studies evaluating specifically the incidence of wound dehiscence following isolated upper blepharoplasty. This is a large-scale upper blepharoplasty review to evaluate the rate of wound dehiscence, to assess risk factors, and to analyze management outcomes. METHODS: A retrospective review was performed of all patients who underwent upper blepharoplasty at a single surgery center. All incisions were closed using either 6-0 fast-absorbing plain gut or polypropylene suture in a running fashion, with an additional interrupted suture near the lateral wound edge. Incidence of wound dehiscence was determined and further assessed by patient age (≤67 or >67 years), gender, preexisting medical conditions, smoking history, and suture type. RESULTS: A total of 1,190 patients (2,376 eyelids) met inclusion criteria. In total, there were 34 instances (1.4%) of wound dehiscence in 32 patients at an average 9 days (range, 0-30 days) following surgery. Evaluation of wound dehiscence rates by demographic factors revealed male gender to be a significant predictor of wound dehiscence (p = 0.0062). Age, hypertension, heart disease, and diabetes were not predictors of wound dehiscence. Lifetime smoking history increased risk for wound dehiscence (p < 0.0001). Use of fast-absorbing plain gut suture was also significantly associated with dehiscence, when compared with polypropylene (p = 0.0025). Multivariate analysis revealed male gender and fast-absorbing plain gut suture to be independent risk factors for wound dehiscence. Seventeen eyelids with wound separation were observed for second-intention healing, 1 underwent delayed scar revision. Fourteen eyelids were repaired primarily using suture and 3 with cyanoacrylate surgical skin adhesive. All patients reported satisfaction with their final outcome, and objective final healing was deemed satisfactory. CONCLUSIONS: Wound dehiscence following isolated upper blepharoplasty is rare and associated with male gender and fast-absorbing plain gut suture. Patients with wound separation may be successfully managed with individualized care.

Atypical acute presentation of an optic nerve sheath meningioma.

PURPOSE: Primary optic nerve sheath meningiomas (ONSM) are benign lesions that typically present with findings of painless proptosis (59%), optic nerve pallor (55%), and decreased peripheral vision (35%). Herein we share an atypical case of a patient who presented acutely with periorbital pain and optic nerve head edema, and was ultimately determined to have a low-grade optic nerve meningioma. OBSERVATIONS: A 36-year-old healthy woman presented with acute onset of left periorbital discomfort. She was found to have intact visual acuity, full peripheral vision, and ipsilateral optic nerve edema. MRI imaging revealed a large intraconal mass partially encircling the left optic nerve. Incisional biopsy revealed a diagnosis of meningioma, WHO grade 1. CONCLUSIONS: Low-grade optic nerve sheath meningiomas may uncommonly present with acute pain and optic nerve head swelling, and absence of classic disease features.

Acute post-partum vision loss due to pilocytic astrocytoma.

PURPOSE: We report an unusual case of a thirty-three-year-old woman who presented with acute unilateral vision loss following pregnancy and was ultimately discovered to have a pilocytic astrocytoma of the optic nerve. OBSERVATIONS: A thirty-three-year-old previously healthy female presented one month following Caesarean section with unilateral vision loss. She was found to have significantly decreased visual acuity, an afferent pupil deficit, proptosis, optic nerve edema and choroidal folds. Imaging revealed a large lesion of the optic nerve. Biopsy was performed and pathologic analysis revealed a pilocytic astrocytoma, WHO grade 1. The patient opted for close observation without further management and demonstrated mild improvement in visual function. CONCLUSIONS/IMPORTANCE: Optic pathway gliomas (OPG) most commonly present in the pediatric patient population with painless proptosis, slowly progressive vision loss, and clinical findings of chronic optic neuropathy.( Farazdaghi et al., 2019 Sep) 1 Acute presentations of this disease in adulthood are rare. This case demonstrates a rare case of acute optic nerve glioma presentation during the post-partum period.
