The Diagnostic Accuracy of First-Year Ophthalmology Residents on Call: Considerations for Postgraduate Year 2 (PGY-2) Standardizations of Call Structure.

Background Ophthalmology is a unique specialty with limited exposure during medical school. To improve the transition to ophthalmology residency, the Accreditation Council for Graduate Medical Education (ACGME) announced in 2017 that all ophthalmology residency programs would move to a combined post-graduate year (PGY) 1 year with mandatory integration by 2023. Currently, there are no standardized guidelines from the American Board of Ophthalmology (ABO) or the Accreditation Council for Graduate Medical Education (ACGME) to address ophthalmology resident competence prior to becoming the primary contact for inpatient and emergency room (ER) consultations as a PGY-2. Novice residents may not be equipped to accurately diagnose vision or life-threatening ocular conditions. A balance between resident autonomy and supervision is required for proper training without increasing patient morbidity and mortality. Objective This study's objective is to examine the diagnostic accuracy of PGY-2 ophthalmology non-integrated residents on call to standardize supervision requirements (through buddy-call) prior to initiating indirectly supervised calls. Methods All inpatient and ER ophthalmology consults for the first seven weeks of the year evaluated by PGY-2 (junior) residents were supervised and graded as "correct" or "incorrect" by PGY-4 (senior) residents. Results One hundred forty-eight consults were seen over 30 call days over a period of seven weeks (4.93 consults per call). The percentage of correct diagnoses increased with each successive week (R2 = 0.9581; correlation = 0.979). The greatest percent increase of correctly diagnosed encounters was between weeks 2 and 3 (19.14%) correlating to call numbers 10-16 and 45-68 patient encounters. The mean percent accuracy surpassed 70% during weeks 3-4, and improvement continued to week 7. High-acuity diagnoses were identified consistently 100% of the time from week 5 onward. Conclusion Our analysis indicated that diagnostic accuracy was greater than 70% between weeks 3 and 4 with high-acuity diagnostic accuracy reaching 100% at week 5. It can be postulated that optimal direct senior resident supervision is needed for at least 3-5 weeks before transitioning to indirectly supervised calls by PGY-2 residents. This standardization would allow junior residents to acquire sufficient clinical experience to accurately make a diagnosis and prevent patient morbidity. Further research nationally is necessary prior to creating a standardized call structure for PGY-2 residents especially with the newly mandatory integrated ophthalmology residency programs.

Longitudinal Comparison of Orbital Volumes from Enucleated Eyes with Hydroxyapatite Orbital Implant in Unilateral Retinoblastoma Patients.

PURPOSE: To compare the orbital volume between enucleated and contralateral, uninvolved orbits over a 5-year period in patients with unilateral retinoblastoma who underwent enucleation with hydroxyapatite (HA) implant placement by a single surgeon. METHODS: A retrospective review was performed on the clinical records and radiographic images of unilateral retinoblastoma patients who underwent enucleation with primary HA implantation from 2003 to 2020 at a single institution. Bilateral orbital volume measurements were taken from the initial postoperative MRI scan and again at 1- and 5-years postenucleation. The main outcome measure was the longitudinal change in volume difference (∆𝑉). The implant size, age at enucleation, and sex were also evaluated. A linear mixed-effect model was used for analysis. RESULTS: A total of 124 patients (73 males) with HA implants following enucleation were included. Overall, the unaffected orbit trended toward having a greater volume compared with the enucleated orbit, but this was not statistically significant (ß = 0.003; p = 0.122). The mean age at enucleation was 2.4 years. The median time between enucleation and the initial, 1-year, and 5-year postoperative MRIs was 6 months, 17 months, and 55 months, respectively. There was no statistical correlation between age at enucleation, gender, implant size, or orbital volume at any time points (p > 0.05). CONCLUSIONS: Patients treated with enucleation and primary HA implant placement for unilateral retinoblastoma did not display significant asymmetry in orbital volume on 5-year postenucleation MRIs, suggesting that HA implants promote orbital growth comparable to a nonenucleated orbit in the pediatric population.

Pediatric Orbital Roof Fractures: A Ratio of Orbital Dimensions Correlated to Prevalence of Fracture.

Objective Orbital roof fractures are more likely to occur in younger children, specifically younger than 7 years. Cranium to face ratio decreases with age; however, there is no definition for measurement of the neurocranium or face. We propose using the length of the orbital roof as a measurement of the neurocranium and length of the orbital floor as a tool to estimate midface size. The purpose of this study is to test this measurement as a correlation rate of orbital roof fractures within the pediatric population. Design This is a retrospective study. Setting This study was done at the LeBonheur Children's Hospital. Participants Sixty-six patients with orbital roof fractures were identified and stratified by gender and age, specifically younger than 7 years and 7 years or older. Main Outcome Measures The main outcome measures were orbital roof length, floor length, and ratio thereof. Results Mean orbital roof length was 43.4 ± 3.06 and 45.1 ± 3.94 mm for patients <7 and ≥7 years, respectively ( p = 0.02). Mean orbital floor length was 41.3 ± 2.99 and 47.7 ± 4.19 for patients <7 and ≥7 years, respectively ( p < 0.00001). The mean roof to floor ratio (RTFR) for patients <7 years was 1.051 ± 0.039 and for patients ≥ 7 years was 0.947 ± 0.031 ( p < 0.00001). Conclusion As children age, the relative length of the orbital roof decreases when compared with the orbital floor. The RTFR was more than 1.0 in children younger than 7 years. These differences were statistically significant when compared with children 7 years and older. This measurement shift follows the differences noted in orbital fracture patterns during childhood.

Spontaneous orbital hemorrhage in a case of acute liver failure.

Purpose: To report an unusual case of spontaneous orbital hemorrhage in the setting of DIC and hepatic failure. Observations: A 33-year-old female presented to the Emergency Department (ED) with acute liver failure. During the first week of her hospital admission, she developed unilateral eyelid swelling and proptosis, prompting a consult to ophthalmology. Additional physical examination revealed significantly decreased visual acuity, extraocular muscle restriction, afferent pupillary defect, and increased intraocular pressure. Computed tomography (CT) and ultrasound confirmed the diagnosis of intraorbital hemorrhage. Aggressive management in the form of lateral canthotomy, cantholysis, and septolysis was unable to be performed due to the patient's multiple comorbidities outweighing the potential benefits. Conclusions and importance: This rare phenomenon is unique from previous existing literature in that the timing of the incident limited the therapeutic options for this patient, additional imaging in the form of ultrasound was utilized in the work-up, and to our knowledge this is the second case of spontaneous orbital hemorrhage as a complication of disseminated intravascular coagulation (DIC) caused by hepatic failure.

Long-acting opioid prescribing patterns of ophthalmic plastic surgeons in the medicare Part D database.

PURPOSE: To assess extended release/long acting (ER/LA) opioid prescribing patterns among ophthalmic plastic surgeons in the Centers for Medicare and Medicaid Services (CMS) Part D database. METHODS: A retrospective observational cohort study was conducted on oculoplastic surgeons in the CMS Part D database who prescribed ER/LA opioids from 2013 to 2017. American Society of Ophthalmic Plastics and Reconstructive Surgery (ASOPRS) and non-ASOPRS surgeons were analyzed as groups. Prescribers were also analyzed based on gender and practice experience. RESULTS: Oculoplastic surgeons (64 ASOPRS and 78 non-ASOPRS) were responsible for 1,177 ER/LA opioid prescriptions from 2013 to 2017. ASOPRS members accounted for 4.6% and non-ASOPRS members accounted for 7.5% of all ER/LA opioids prescribed by ophthalmologists over the study period (p= .02). The total number of ASOPRS and non-ASOPRS members prescribing ER/LA opioids decreased by 52% (p= .10) and 58% (p= .07) from 2013 to 2017 respectively. CONCLUSION: ER/LA opioids are indicated for treatment of chronic pain and may be appropriately prescribed by the oculoplastic surgeon in certain circumstances, however due to the higher risk of overdose injury, those circumstances must be defined and justified. While a relatively small number of oculoplastic surgeons (10.6% ASOPRS and 19.6% non-ASOPRS) prescribed ER/LA opioids from 2013 to 2017, non-ASOPRS oculoplastic surgeons wrote 23.5% more ER/LA opioid prescriptions over the study period. Over the 5-year study period there was a general decline in the prescribing of ER/LA opioids by oculoplastic surgeons. Reviewing the prescribing practices of oculoplastic specialists, regardless of professional affiliation, is necessary to understand the role of ER/LA opioids for all of ophthalmology.

Effect of Premature Tube Extrusion for Simple Congenital Nasolacrimal Duct Obstruction: A Comparison of Monocanalicular and Bicanalicular Intubation.

ABSTRACT: The objective of this article is to compare the incidence of premature dislocation of silicone tubes and the effect on treatment success between monocanalicular (MCI) and bicanalicular (BCI) intubation in pediatric patients with simple congenital nasolacrimal duct obstruction. Retrospective comparative case series of 108 eyes of 78 pediatric patients with simple congenital nasolacrimal duct obstruction who underwent probing with either BCI (n = 38 eyes) or MCI (n = 70 eyes) from 2017 to 2020. Premature tube extrusion was defined as any tube removed prior to the 3 month postoperative appointment. Success was defined as resolution of tearing 3 months post tube removal. Ages ranged from 10 months to 5.35 years (mean, 1.95 years; Standard deviation (SD), 0.91). Premature tube extrusion occurred in 15 eyes with BCI and 29 eyes with MCI. Success rates were not significantly different regardless of intubation type between the planned tube removal (90.6%) and the premature tube extrusion cohorts (84.1%), P = 0.89. There was no significant difference in treatment success between the planned tube removal (92.7% MCI, 87% BCI) and the premature tube extrusion cohorts (86.2% MCI, 80% BCI). Complications included 2 infections (1 MCI, 1 BCI) and 2 cases of tube related keratopathy (1 MCI, 1 BCI) that all resolved with tube removal. There were 2 BCI patients that presented to the emergency department for premature tube extrusion. Silicone intubation regardless of stent type is an effective treatment for simple congenital nasolacrimal duct obstruction. There was no significant difference in treatment success between tubes that extrude prematurely, and tubes removed at term based on type of intubation.

Opioid Prescribing Patterns of Optometrists in the Medicare Part D Database.

SIGNIFICANCE: This study aimed to determine the prescription rates and prescribing trends of opioids by optometrists in the Centers for Medicare & Medicaid Services (CMS) part D database from 2013 to 2017 and to assess opioid prescribing patterns of U.S. optometrists in the CMS part D database. METHODS: With internal review board approval, a retrospective observational cohort study was conducted on optometrists listed in the CMS part D database who prescribed opioids from 2013 to 2017. RESULTS: There was an average of 26,477 optometrists in the CMS database from 2013 to 2017, of which 5.9% prescribed opioids. Of those prescribing opioids, optometrists wrote an average of 5.9 opioid prescriptions per year. Those writing greater than 10 opioid prescriptions averaged 24.2 annually. Overall, of opioid prescribing optometrists, opioid prescriptions comprised 7% of prescriptions written per year. CONCLUSIONS: Most optometrists do not prescribe opioids, and the vast majority of those who do write few opioid prescriptions. The total number of optometrists prescribing opioids and the total number of opioid prescriptions declined from 2013 to 2017. Further investigation into the opioid prescribing practices by optometrists will help better understand specific pain needs, as opioid prescribing patterns may differ depending on patient population.

Total or subtotal replacement of tarsal plate by novel silicone plate for upper eyelid reconstruction in malignant tumors.

PURPOSE: : To evaluate the cost, safety, surgical outcome, and efficacy of modified Cutler-Beard eyelid reconstruction utilizing a novel silicone plate as a tarsal plate replacement in the repair of 60% to 100% eyelid defects following the excision of large malignant tumors. METHODS: : A prospective, noncomparative, interventional study of 30 eyes was done over 3 years. Fourteen patients were female, and 16 patients were male. In all the cases, a silicone plate, the synthetic, artificial tarsal plate, was utilized for a total or subtotal replacement of the tarsal plate. The created defect was measured in mm (length and width) and later expressed in percentage. Pre- and postoperative action of levator palpebrae superioris (LPS) was measured. Pre- and postoperative measurements of the margin-to-margin reflex distance (MRD1) were noted. RESULTS: : Preoperative LPS action was 1.23 ± 1.35 mm, whereas postoperative LPS actions at the end of 1 week and 18 months were 11. 8 ± 0.88 mm and 13.53 ± 0. 73 mm, respectively. Preoperative MRD1 was - 3.0 ± 1.144 mm, whereas postoperative MRD1 values at the end of 1 week and 18 months were 2.18 ± 0.27 mm and 4.16 mm ± 0.35, respectively. The mean created defect after the removal of the tumor was 87.3% ±11.10. The mean length of the silicone plate implanted in this study was 27.53 ± 2.48 mm. The follow-up period for the study participants was 18 months. CONCLUSION: : The synthetic novel silicone plate was successful as a tarsal plate replacement. A second surgical site for ear cartilage harvesting is avoided. Cadaver transfer of Achilles tendon carries the risk of transmission of communicable diseases, for example, hepatitis B and HIV. Silicone is an inert, nonreacting, and tissue-tested material, thus eliminating the possibility of graft rejection. This material is readily available and cost-effective. The novel silicone plate is considered to be the most promising alternative material as a tarsal replacement in the future generation.

Management of Eye Trauma for the Primary Care Physician.

Eye trauma is frequently seen by non-ophthalmology providers. This article elucidates a methodological approach to eye trauma. The first step is to address any life-threatening conditions. Then a focused history and exam is discussed, starting externally. Then, key history, physical, pathophysiology, and basic management of common, serious eye injuries are discussed: chemical injury, orbital fractures, open globe, traumatic hyphema, retinal detachment, traumatic optic neuropathy, and eyelid laceration. Finally, we highlight the practicality of telemedicine for areas where ophthalmology coverage is lacking.

Allergic Fungal Sinusitis: Ophthalmic Complications Due to the COVID-19 Pandemic and the Potential of Telemedicine.

We report a case of a 26-year-old female who initially presented to an outside optometrist with complaints of proptosis and decreased visual acuity. Magnetic resonance imaging (MRI) obtained at that time was concerning for allergic fungal sinusitis. Unfortunately, the patient's referral to ophthalmology was delayed due to the coronavirus disease 2019 (COVID-19) pandemic. On presentation to ophthalmology one year later, the patient had clinically deteriorated with significant visual and olfactory loss. She underwent emergent endoscopic sinus surgery by otolaryngology with histological analysis of the sinus debris confirming allergic fungal sinusitis. This is a unique case demonstrating the devastating impact that the COVID-19 pandemic had on patient care for an otherwise treatable condition. We propose the utilization of telemedicine networks as a way to prevent similar complications.

Postoperative Clinical Outcomes Using Standard Variables Following Levator-Mullerectomy Advancement Blepharoptosis Surgery.

ABSTRACT: The Muller muscle-conjunctival resection is a common technique used to treat blepharoptosis, but there is variability with the target surgical resection and expected postoperative outcomes measured by marginal reflex distance-1 (MRD1). A Levator-Mullerectomy is a novel surgical approach described by Morris et al to incorporate the levator palpebrae superioris in the same incision as the classic Muller muscle-conjunctival resection in the treatment of blepharoptosis. This a retrospective study of patients who underwent Levator-Mullerectomy for ptosis repair showing the clinical outcomes based on MRD1. Statistical analysis was performed using analysis of variance and a nonparametric Kruskal-Wallis test. One hundred-twelve eyes of 83 patients (29 bilateral cases) with a mean age 64.6 years (7-92 years) were included. The types and prevalence of blepharoptosis were involutional (83%), neurogenic (8.0%), traumatic (3.6%), apraxia (2.7%), and congenital (2.7%). There was no significant difference in clinical outcome based on type of blepharoptosis (P = 0.7). Target resection lengths of 8 mm, 10 mm, and 12 mm were compared with postoperative MRD1 change. The mean change in MRD 1 between 8 mm and 10 mm was found to be statistically significant (P = 0.001 for both) but was not statistically significant for the 12 mm resection (P = 0.8). In patients with blepharoptosis and a positive response to 2.5% phenylephrine can benefit from Levator-Mullerectomy with either an 8 mm or 10 mm resection. This novel surgical approach allows surgeons to produce a more predictable and consistent clinical outcome.

A Case of Orbital Granuloma Secondary to Dermal Filler Injection.

A foreign body granulomatous reaction is a rare complication of the subcutaneous injection of fillers. We describe a 57-year-old female that presented with a six-month history of a non-painful, right lower eyelid mass. She had a dermal filler in the zygomatic region several months before the onset of her symptoms. Anterior orbitotomy and pathology revealed multinuclear giant cells consistent with a hyaluronic acid-based filler. This case describes the clinical presentation, histopathologic features, and treatment of an orbital granuloma secondary to dermal filler injection. Our case was uncommon because the zygomatic filler migrated across the orbital septum. Additionally, transconjunctival orbitotomy was used instead of a hyaluronidase injection due to the inferior location of the granuloma.

Unilateral Abducens Nerve Palsy Following Perinatal Stroke of the Middle Cerebral Artery.

The authors describe a case of unilateral abducens nerve palsy following perinatal stroke of the middle cerebral artery. A 1-year-old boy presented with left eye esotropia but no other ocular abnormalities. The patient's history, examination, and diagnostic tests were consistent with abducens nerve palsy. He underwent left medial rectus recession of 5.5 mm and left lateral rectus resection of 7 mm followed by patching. At 15 months after surgery, primary gaze by prism alternate cover testing revealed a 4 prism diopter (PD) esophoria (small angle in left gaze with essentially no action of lateral rectus) and 2 PD right hyperphoria. Ophthalmologic management of abducens nerve palsy entails addressing neurological sequelae in a timely manner, treating the esotropia and strabismic amblyopia to optimize visual system development.

A Case of Non-Arteritic Anterior Ischemic Optic Neuropathy with COVID-19.

Non-arteritic ischemic optic neuropathy (NAION) is thought to be caused by loss of blood flow to the optic nerve which in turn causes an acute, unilateral and painless vision loss that affects older vasculopathic patients. We report a case of a 43-year-old Hispanic male with the classic presentation of NAION in the setting of a coronavirus disease 2019 (COVID-19) infection. It is well documented that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can cause hypoxemia and thrombophilia in patients, both of which may contribute to the development of NAION. It is uncertain whether the association of NAION and COVID-19 was causal or coincidental but the purpose of this case report is to argue that there is biological plausibility and to help shed light on potential ophthalmologic complications of COVID-19.

Essential skin shrinkage: cicatricial ectropion, a histopathologic evaluation and clinical analysis.

Purpose: To describe common risk factors in patients with Essential Skin Shrinkage (ESS) and identify corresponding histopathologic changes in lower eyelids.Methods: A case-control study was performed after an Internal Review Board approval was obtained. Consecutive patients who underwent surgical repair for ectropion with ESS of the lower eyelid were enrolled along with 10 control patients. Informed consent was obtained on all patients. Fitzpatrick skin type, history of sun exposure and non-melanoma skin cancer was obtained along with relevant physical exam findings. Skin samples obtained during surgical repair were evaluated by light microscopy for the extent of dermal actinic change. Statistical analysis was performed.Results: Sixteen study subjects and 10 control patients were enrolled. Subjects were found to be predominantly male, older than controls (p = 0.0011) and have Fitzpatrick skin type (FST) I or II while controls had type I, II or III (p = 0.0221). Hours of sun exposure reported by subjects ranged from 23,165 to greater than 125,000 h, versus 1,459 to 46,890 h in controls (p = 0.0002). Nine of 16 (56%) subjects had a history of skin cancer compared to only 3/10 controls (30%) (p = 0.2475). Histopathologic evaluation using the Fritschi scale for dermal actinic damage identified an average grade of 3.6 for subjects and 2.4 for controls (p = 0.0095).Conclusions: ESS is predominantly seen in male individuals with FST I or II and a history of extensive sun exposure. Histopathologic evaluation shows moderate to severe actinic damage. These individuals frequently have concomitant non-melanoma skin cancer.

Canthal V-plasty for Floppy Eyelid Surgery.

The purpose of this article is to present a modified approach to the reconstruction of the upper and lower eyelids in floppy eyelid syndrome. A retrospective chart review was performed on all floppy eyelid patients who underwent simultaneous tightening of the upper and lower eyelid with a lateral tarsal strip, using a V-shaped incision in the lateral canthus, at University of Tennessee Hamilton Eye Institute from 2011 to 2012. Preoperative symptoms, surgical outcomes, complication rates, and postoperative symptoms were recorded. Nine eyes of 7 patients who underwent surgical correction for symptomatic floppy eyelids were included. All patients noted improvement in symptoms postoperatively, after reduction in the laxity of the upper and lower eyelid. Postoperative complications included buried lashes in the lateral canthus in 1 eye and a pyogenic granuloma in the lateral canthus of 1 eye. An excellent cosmetic outcome was noted in 78% (7/9) of eyes. No patients reported dissatisfaction nor required secondary surgical correction. The lateral canthal "V" incision provides an additional approach in the successful management of floppy eyelid syndrome involving the upper and lower eyelids. The design of the incision allows for excellent exposure of the lateral canthus for shortening of the eyelids with tarsal strip fixation, and it preserves the lateral canthal skin and canthus architecture. Further, the "V" incision is easily continued into the eyelid crease for blepharoplasty and ptosis repair when necessary.

Orbital Pheochromocytoma Metastasis in 2 Patients With Known Pheochromocytoma.

Two patients with previously diagnosed pheochromocytoma presented with facial pain and ptosis. Imaging revealed orbital lesions. Both patients were referred for surgical evaluation of the orbital mass. Surgical excision was performed for both. Pathology confirmed metastatic pheochromocytoma. Pheochromocytomas commonly metastasize to bone, liver, and other tissues. Five cases of metastasis to orbital bone have been previously described. These 2 cases are unique in that the metastases were not hormonally active, presented soon after initial diagnosis, and were treated palliatively with surgical excision. Previous treatment of orbital bony metastasis used radiotherapy. These cases demonstrate that surgical resection is a viable treatment option in these situations. Orbital metastasis of pheochromocytomas should be considered with the appropriate clinical presentation. These are the first documented cases of intraorbital metastasis, separate from the bony walls. Previously, orbital bony wall metastases were treated with radiation. Surgical excision is a viable option for treatment of such metastases.Orbital involvement should be considered in patients with systemic disease presenting with new ocular findings.

Intravascular Papillary Endothelial Hyperplasia of the Orbit: A Case of Masson's Tumor.

Herein, we present a case of a 64-year-old male presenting with diplopia that was found to have a left orbital Masson's tumor. It is necessary to differentiate it from malignant angiosarcoma as complete excision is often curative. The following case emphasizes the modalities that can be used for diagnosis as well as the appropriate treatments.
