Management of an ophthalmology department during COVID-19 pandemic in Milan, Italy.

PURPOSE: Spreading from China, COVID-19 pandemic reached Italy, the first massively involved western nation. At the beginning of March, 2020 in Northern Italy a complete lockdown of activities was imposed. Access to all healthcare providers, was halted for patients with elective problems. We present the management experience of the Humanitas Clinical and Research Center Ophthalmology Department in Rozzano, Milan, Italy, during the lockdown. METHODS: Containment measures were taken to reduce viral transmission and identify infected patients. All planned visits were canceled but for those not deferrable. Social distancing was introduced reducing number of visits per hour. Minor surgery for progressive pathologies was continued. As the lockdown prolonged, we reorganized patient care. All canceled cases were evaluated by electronic medical records analysis and telephonic triage, to identify, recall, and visit patients at risk of vision loss. RESULTS: From March 9, to April 30, 2020 we performed a total of 930 visits and 612 exams. Some visits (n = 698) and exams (n = 160) were deemed as necessary for continuity of care and performed as planned. Among the remaining 1283 canceled appointments, after evaluation 144 visits and 32 instrumental exams were classified as urgent and rapidly rescheduled. Performed surgical activities were limited to corneal collagen cross linking (n = 39) and intravitreal injections (n = 91), compared to 34 and 94, respectively, in the same period of 2019. CONCLUSION: In-office activities deemed not deferrable were performed safely. The recall service was highly appreciated by all patients. No patient or staff member reported symptoms of COVID-19.

Epiphora and unrecognized paranasal sinuses pathology.

PURPOSE: to report five patients all presenting with persistent unilateral epiphora as a sign of unexpected and rare lesions causing Secondary Acquired Nasolacrimal Duct Obstruction (SANDO) and the risks associated to an incomplete diagnostic work-up. OBSERVATIONS: the cases presented are: (1) Fungus ball, (2) Pyogenic granuloma, (3) Sinonasal inverted papilloma (4) Sinonasal inverted papilloma with synchronous squamous cell carcinoma, (5) Squamous cell carcinoma of the lacrimal sac. CONCLUSIONS AND IMPORTANCE: masses are uncommon but not a rare cause of nasolacrimal duct obstruction. Surgical teams performing large numbers of dacryocystorhinostomies should be aware of such pathology and perform a systematic multidisciplinary approach.

Autologous fat graft in irradiated orbit postenucleation for retinoblastoma.

Autologous fat grafting has been extensively and successfully adopted in a number of pathologic conditions in regenerative surgery especially on irradiated fields in order to improve pain symptoms and tissue trophism promoting scar release. In the present study, we report our experience with autologous fat grafting for the treatment of postirradiation fibrosis and pain on three consecutive patients undergoing orbital enucleation for locally advanced retinoblastoma (RB) and subsequent radiotherapy. We selected three consecutive patients who underwent orbital enucleation for locally advanced RB and subsequent local radiotherapy showing severe reduction in orbital volume and eyelid length and retraction due to fibrosis, spontaneous local pain exacerbated after digital pressure with no possibility to place an ocular implant. They underwent autologous fat grafting in the orbital cavity and results were evaluated by clinical examination at 5 and 14 days, and 1, 3, 6 months, and 1 year after surgery. A significant release of scar retraction, reduction of fibrosis and orbital rim contraction together with an important improvement of pain symptoms was observed in all patients. The local changes observed enabled an ease placement of an ocular prosthetic implant (implant). No local or systemic complication occurred. Fat grafting is a promising treatment for patients showing radiotherapy related complication in the orbital area and it should be adopted by all oculoplastic surgeon in order to improve pain syndrome creating the ideal local conditions for the placement of an ocular prosthetic implant.

Paraneoplastic syndrome--unresponsive systemic hypertension and fever as expression of primitive ciliary body carcinoma in a blind painful eye: a case report.

BACKGROUND: The purpose of this study was to present a case of paraneoplastic systemic hypertension and fever in an undiagnosed primary ciliary body carcinoma arising in a painful blind eye. CASE PRESENTATION: A 37-year-old white man with a history of blindness since childhood was enucleated for neovascular glaucoma because of intractable pain in his right eye. A histopathological examination revealed a ciliary body carcinoma. One year later, an invasive recurrence of his orbit and ethmoid was detected and a debulking procedure was performed. He had untreatable fever and multidrug-resistant systemic hypertension for 3 months before the neoplasm diagnosis. He recovered from fever and systemic hypertension only after tumor excision and relapsed 1 year later when synchronous tumor dissemination was shown through a computed tomography scan. Tumor metastases, despite surgery and chemotherapy, caused his death. CONCLUSIONS: Paraneoplastic symptoms such as fever and hypertension may be due to unrecognized ocular malignancy. This case report intends to emphasize the importance of histopathological examination of an enucleated phthisical painful blind eye.

Orbital exenteration: our experience.

INTRODUCTION: We reviewed our experience of the multidisciplinary collaboration between ophthalmologists, head and neck surgeons, neurosurgeons, radiologists and oncologists in the management of extensive tumors treated by orbital exenteration at the Humanitas Research Institute, Milan, Italy, over the past 10 years. METHODS: This is a retrospective cohort study of all patients who underwent orbital exenteration between March 2005 and August 2014 at the Humanitas Research Institute. The 10-year cohort of exenterated patients was identified through operating room notes using the clinical code set of the International Classification of Diseases, 10th revision (ICD-10). RESULTS: A total of 26 patients were identified, including 19 (73.1%) males. The median age was 65.5 years (range 37-87). Eighteen (69.2%) patients had major skin cancers extending to the orbit. Patients were divided into 2 cohorts: cohort 1 comprising patients with sinus or craniofacial cancers requiring orbital exenteration, and cohort 2 comprising patients with advanced periorbital skin cancers. The two cohorts were well matched for sex, age at surgery, degree of invasion, extension of surgical removal, necessity of adjuvant radiotherapy, reconstruction processes, and rehabilitation. CONCLUSIONS: In our experience patients never died of the primary lesion but because of the occurrence of other problems. So we encourage local surgical radicality.

Secondary orbital and intraocular lymphoma treated with immunochemotherapy.

PURPOSE: To assess ocular and orbital structure by ocular echography and magnetic resonance imaging, fluoroangiography, indocyanine green angiography, and optical coherence tomography before and after therapy with rituximab (Mabthera) and chlorambucil in a patient with concurrent intraorbital and intraocular lymphoma and diplopia. METHODS: A 69-year-old man referred blurred vision and proptosis in his left eye associated with diplopia. Best-corrected visual acuity was 0.3 logarithm of the minimum angle of resolution in the left eye and 0.02 logarithm of the minimum angle of resolution in the right eye. Ocular echography and magnetic resonance imaging revealed the presence of concurrent orbital and intraocular tumor, and a B-cell lymphocytic lymphoma was diagnosed by incisional biopsy. The patient was treated with the oral alkylating agent chlorambucil and with intravenous infusions of the monoclonal anti-CD20 antibody rituximab (Mabthera) and evaluated with visual acuity, echography, fluoroangiography, indocyanine green angiography, and magnetic resonance imaging. RESULTS: After combined immunochemotherapy with rituximab/chlorambucil, the patient showed in the left eye a significant improvement of visual acuity (0.1 logarithm of the minimum angle of resolution) and a disappearance of diplopia at the end of follow-up. CONCLUSION: In this case report, combined systemic therapy with chlorambucil and rituximab was effective to reduce and control orbital and intraocular lymphoma.

Evaluation of intraorbital injection of rituximab for treatment of primary ocular adnexal lymphoma: a pilot study.

An interventional pilot study to assess the tolerability and activity of the intralesional injection of rituximab, a chimeric mAb that targets the CD20 antigen, in patients with orbital B-cell lymphoma. Five patients received four intralesional injections (one injection a week) of rituximab together with ropivicaine 2%. Side-effects and tumor response were assessed after each injection and during the follow-up (20 months). Two patients obtained complete remission of the intraorbital lesion. Two patients showed incomplete response after induction therapy and received planned escalating rituximab doses, obtaining regression of subjective symptoms. One patient did not achieve tumor regression after the first injection and underwent systemic treatment. This small exploratory study suggests that intralesional rituximab is a well-tolerated treatment for patients with primary ocular adnexal lymphoma. These preliminary findings suggest that intralesional rituximab is a well-tolerated strategy in anterior intraorbital lesion localization of lymphoma.

Mydriasis induced by sub-Tenon's ropivacaine injection in patients undergoing strabismus surgery.

PURPOSE: To investigate the effects of sub-Tenon's capsule ropivacaine injection on pupillary diameter in strabismus surgery. METHODS: A total of 16 patients were randomly assigned to 2 groups. The ropivacaine group (R) received sub-Tenon's ropivacaine 1% (2.5-3 mL) injections. In the control group (C), general anesthesia was induced and a saline solution (2.5-3 mL) was injected in the sub-Tenon's capsule. Pupillary diameter was measured at baseline and 2 and 5 minutes from the injections. The effects of the injections were expressed as a ratio of final (5 minutes) versus basal diameter. RESULTS: A significant mydriasis occurred in the ropivacaine group when compared with the control group (Group R vs Group C ratio = 2.32, p < 0.0001) or with unoperated fellow eye (R vs unoperated eye ratio = 2.29, p < 0.0001). CONCLUSIONS: Ropivacaine in the sub-Tenon's capsule induces a mydriasis probably related to a pharmacological ciliary ganglion block.

Surgical treatment of obstruction of the nasolacrimal ducts in patients with anatomical endonasal variants.

The presence of anatomical endonasal variants (concha bullosa, nasal septal deviation, or hypertrophic turbinates) may cause more complications in patients with epiphora who have external dacryocystorhinostomy (DCR). The purpose of this study was to assess the results of surgical placement of a stent in 28 patients. They were randomised into two groups and had either DCR or placement of a Song's polyurethane stent. They were followed up for 18 months. Twenty-six patients had a good result. The success rate was 13/14 for those who had DCR and 13/14 for those who had a stent. Operating time was significantly less for placing a stent (mean (SD) 15 (2) minutes) compared with 40 (3) minutes for DCR (p <0.01). Placement of a polyurethane stent is an effective and short procedure for nasolacrimal obstruction, which is suitable for patients with unusual intranasal conditions.
