Peri-orbital Masson's tumor: a case report and literature review.

Masson tumor is a benign vascular lesion characterized by an intravascular papillary endothelial hyperplasia. Peri orbital locations are rare. We report a case of Masson tumor localized in the upper internal angle of the left orbit revealed by progressive ocular proptosis. Orbital computed tomography (CT) scan and magnetic resonance imaging (MRI) showed a vascular mass in the left internal canthus mimicking an arterioveinous malformation. The patient underwent total removal of the lesion with a favorable postoperative follow up. Histological examination found an intravascular papillary endothelial hyperplasia without atypical features corresponding to Masson tumor. A thorough literature review of Masson tumor is presented with a discussion of clinical findings and management.

Acute Vision Loss and Conjunctival Hemorrhage as Telltale Symptoms of PIMS-TS.

There is a global concern about children presenting with inflammatory syndrome with variable clinical features during the ongoing COVID-19 pandemic. This paper reports the first pediatric case of bilateral serous retinal detachment and conjunctival hemorrhage as a revealing pattern of the pediatric inflammatory multisystem syndrome temporally associated with SARS-CoV-2 (PIMS-TS). Despite the severity of multisystemic involvement, the management with steroids was very successful. Complete remission was obtained within 3 months of acute onset.

Third Cranial Nerve Palsy Presenting with Unilateral Diplopia and Strabismus in a 24-Year-Old Woman with COVID-19.

BACKGROUND Coronavirus disease (COVID 19) is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and is the causative agent of a serious disease that is of great global public health concern. Palsy of the third cranial nerve is very rare in patients with confirmed 2019 novel coronavirus disease (COVID-19). We describe the case of a patient with an incomplete palsy of the left third cranial nerve sparing the pupils in the context of SARS-CoV-2 virus infection. CASE REPORT We report the case of a 24-year-old woman with confirmed COVID-19, which presented with acute onset of diplopia and strabismus of the left eye that occurred 3 days after the start of general symptoms. The patient had no significant medical history. Based on detailed ophthalmic and neurological examination, acute painless incomplete palsy of the third cranial nerve was suspected. Oculo-cerebral magnetic resonance angiography was unremarkable. Blood tests revealed mild normocytic regenerative anemia. According to the Moroccan recommendations, chloroquine and azithromycin were started. After what, a quick improvement of exotropia and diplopia was observed, and complete recovery was obtained by the sixth day of treatment. No adverse effects of the treatment were noted. CONCLUSIONS Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can cause neurological complications such as cranial nerve palsy. The pathological mechanism remains unclear. Full recovery of the ocular motricity is possible, and prognosis depends on the severity of the respiratory illness.

Intrastromal injection of voriconazole as a therapeutic of fungal hypopyon: a case report.

We describe the case of a 7-year-old child, victim of ocular trauma causing a corneal wound that was sutured urgently. The child has been regularly monitored in our department. Few months later, he consults for a painful red eye evolving within two weeks. The use of voriconazole as an intracameral injection has shown its superiority in treating fungal endophtalmitis. Further studies should be underwent to learn more about better injection strategies and so as to consider better its benefits and side effects.

[Treatment of retinal detachment of the pseudophak: vitrectomy without episcleral indentation versus ab externo surgery]. / Le traitement du décollement de rétine du pseudophaque: vitrectomie sans indentation épisclérale VERSUS Chirurgie Ab externo.

Several factors predispose to the occurrence of rhegmatogenous retinal detachment, including cataract surgery, myopia, and degenerative lesions of the peripheral retina as well as eye trauma. This study aims to compare the anatomical and functional outcome of the two surgical techniques (AB interno vs AB externo) in our Hospital. We conducted a descriptive, retrospective study in the Department of Ophthalmology at the University Hospital Mohamed VI in Marrakech, over a period of 3 years, ranging from January 2013 to December 2015. During the study period we compared two groups of people: the first group undergoing surgery by an external approach (cryoapplication of the dehiscences with episcleral indentation) while the second undergoing surgery by endo-ocular approach. Group A or AB externo group included 26 eyes (26 patients) while Group B or vitrectomy with internal tamponade group included 22 eyes (22 patients). In the AB externo group, the average age was 54.92 years against 51.64 years in the AB interno group, with a slight predominance of males in both groups. After the first surgery, retinal reapplication was obtained in both groups with no significant difference, (about 80.76% in Group A versus 81.82% of the second group). In both groups failure was caused advanced vitreoretinal proliferation (4 cases), de novo breaks (3 cases) and breaks which had not been detected on first examinations (2 cases). All these cases underwent reoperation by AB interno approach: patients of group A underwent complete vitrectomy with revision of the indentation +/- internal limiting membrane peeling with internal gas tamponade while patients of group B underwent complementary vitrectomy with dissection of proliferative vitreoretinopathy (PVR) and an internal tamponade with silicone oil. After a mean follow-up period of 12 months, there was no significant difference in visual acuity between the 2 groups, with more than one third of the patients who had regained visual acuity between 1/10 and 5/10 (about 34,61% in AB externo group and 36,36% in AB interno group). Given the technological advances in vitrectomy, the current trend is the endo-ocular surgery however ab-externo surgery is mainly used in the treatment of retinal detachment with visible breaks which can be easily treated with indentation without advanced vitreoretineal proliferation (PVR A-B).

Central retinal vein occlusion in a patient on hemodialysis secondary to antiphospholipid syndrome: Case report.

Central retinal vein occlusion (CRVO) is one of the most common retinal vascular disease. Macular edema associated is responsible of the major decrease in visual acuity. The main causes often implicated are high blood pressure and diabetes. Other etiologies should be sought including CRVO secondary to antiphospholipid syndrome (APS). This rare etiology is associated with a poor prognosis when late diagnosed. Owing to the high associated mortality, early diagnosis and prompt treatment are necessary. We describe a case of APS complicated by a catastrophic antiphospholipid syndrome in a patient who presented a decrease visual acuity.

[Corneal transplantation: study carried out at the Department of Ophthalmology, University Hospital Center Mohammed VI, Marrakech]. / Greffe de cornée: expérience du service d'ophtalmologie au CHU Mohammed VI de Marrakech, Maroc.

Penetrating keratoplasty is one of the most common tissue grafts and organ transplantations. The aim of our study was to report our experience in corneal transplantation. A prospective study of 195 patients who underwent corneal transplantation over the period from August 2009 to August 2015. Mean follow-up was 21 months. The indications for transplantation were keratoconus 33,8%, trauma-related sequelae 10,7%, bullous keratopathy 19,5%, hereditary dystrophies 10,7% and herpes keratitis 9,2%. Initial visual acuity was less than 1/10 in 90% of the cases. We observed corneal graft rejection in 19 eyes (14 were recoverables), 33 ocular hypertonia, 20 cataracts, 2 without significant pathological history. Corneal transplantation appears as a surgical intervention giving good anatomical and functional results. The results should not obscure a close and regular post operative monitoring to screen for possible complications, especially graft rejection.
