Purpose: To assess the clinical efficacy and safety of T2769, a new preservative-free eye drop combining hyaluronic acid (HA), trehalose and N-acetyl-aspartyl-glutamic acid (NAAGA), in dry eye patients., Patients and Methods: This was a multicenter, non-comparative, open-label study. After a run-in period with NaCl 0.9% solution, 62 patients with moderate-to-severe dry eye disease (DED) were included and treated with T2769, 3 to 6 times/day for 42 days. The primary efficacy endpoint was the change in global ocular symptomatology assessed on a visual analog scale between Day 1 (D1) and D42. Other efficacy endpoints included ocular surface disease index (OSDI), soothing sensation, individual dry eye symptoms, conjunctival hyperemia, global ocular staining, tear break-up time, Schirmer test, and global efficacy assessed by the investigator. Safety was assessed throughout the study., Results: A marked reduction in ocular symptomatology was observed from D1 to D42 with a mean change of -55.9±23.1mm (P<0.001). This was accompanied by a mean change in OSDI score from baseline of -44.6±15.9 (P<0.001) and a substantial soothing sensation in 82.3% of patients. Clinically significant improvements were observed for all ocular symptoms (mainly burning/irritation, stinging/pain, feeling of ocular dryness, foreign body sensation, itching/pruritus). Conjunctival hyperemia significantly decreased in 96.8% of patients (56.5% displayed no conjunctival hyperemia at D42 versus 0% at baseline). All signs and symptoms improved by D14 and further improved at D42. Investigators assessed the ocular efficacy of T2769 as very satisfactory or satisfactory for 91.9% of patients at D42. T2769 was well tolerated, with no ocular adverse events and only a few ocular symptoms upon instillation., Conclusion: Management of moderate-to-severe DED patients with the new formulation T2769, combining NAAGA to HA and trehalose, led to rapid and significant improvements in dry eye signs and symptoms with good tolerability., (Copyright © 2024.

An 18-year-old female patient was referred with complaints of tearing and redness in the left eye for 3 months after a mild ocular trauma with a turkey feather. She was treated with topical antibiotics and corticosteroids with no improvement. Slit-lamp examination of the left eye showed a vascularized lesion with a polypoidal appearance due to multiple contiguous micronodules on the temporal and inferior bulbar conjunctiva. Results of the anterior and posterior segment examination were unremarkable in both eyes. A biopsy specimen of the conjunctival mass showed multiple tuberculoid granulomas composed of epithelioid histiocytes with associated Langhan's type multinucleate giant cells and a necrotic nodule surrounded by histiocytes and giant cells. The Mantoux test was positive with induration of 15mm. The patient was prescribed antituberculosis therapy. Three months after treatment initiation, the conjunctival lesions had resolved. Mycobacterium tuberculosis should be considered in cases of unilateral chronic recalcitrant conjunctivitis. Biopsy of a conjunctival mass is of utmost importance to establish a definite diagnosis., (Copyright © 2022 Elsevier Masson SAS. All rights reserved.)

Purpose: To describe clinical features, relevant imaging findings, disease course, and response to treatment in 9 patients (18 eyes) with idiopathic retinal vasculitis, aneurysms, and neuroretinitis (IRVAN) syndrome., Methods: Retrospective review of the charts of nine patients (18 eyes) diagnosed with IRVAN syndrome at Fattouma Bourguiba University Hospital, Monastir, Tunisia, from January 1, 2011 to January 1, 2022., Results: Nine patients were included with bilateral involvement in all cases. Mean initial best-corrected visual acuity (VA) was 20/32 (range, 20/1600-20/20). Clinical findings at presentation included vitreous cells (10 eyes, 55.6%), peripapillary exudates (12 eyes, 66.7%), partial or complete macular star (11 eyes, 61.1%), and vascular sheathing (11 eyes, 61.1%). Fluorescein angiography showed arteriolar aneurysms (18 eyes, 100%), areas of peripheral capillary non-perfusion (16 eyes, 88.9%), and retinal neovascularization (6 eyes, 33.3%). Optical coherence tomography showed macular edema in 5 eyes (27.8%). Optical coherence tomography angiography of the optic disc demonstrated papillary aneurysms in 4 eyes of 2 patients. Indocyanine green angiography showed retinal arteriolar aneurysmal dilatations in 4 eyes of 2 patients. Ten eyes (55.6%) had stage 2 disease, 6 eyes (33.3%) had stage 3, and 2 eyes (11.1%) had stage 1. Treatment modalities included peripheral photocoagulation (16 eyes, 88.9%), intravitreal bevacizumab (4 eyes, 22.2%), and intravitreal triamcinolone acetonide (1 eye, 5.6%). Mean final best-corrected VA was 20/32 (range, 20/600-20/20). Ocular complications included vitreous hemorrhage in 3 eyes (16.7%), branch retinal artery occlusion in 2 eyes (11.1%) and submacular fibrosis in 3 eyes (16.7%)., Conclusion: IRVAN syndrome should be highly suspected in patients with peripapillary exudates associated with vascular sheathing and vitreous cells. Multimodal imaging confirms the diagnosis by showing retinal macroaneurysms. Early treatment of macular edema and/or peripheral retinal non-perfusion is mandatory to improve prognosis., (Copyright © 2022 Elsevier Masson SAS. All rights reserved.)

Purpose: We report the case of a patient presenting with a one-sided orbital metastasis from a cutaneous melanoma, and analyze clinical features, diagnostic difficulties and prognosis of such metastasis., Case Report: We report the case of a woman aged 70 years, who presented with a right one-sided proptosis associated to a decrease of the vision. The clinical features were: visual acuity at 2/10, an axile proptosis and a papillary sectorial temporal atrophy. The computed tomography (CT) disclosed an intraorbital mass with double tonality, rounded and well limited driving back the optic nerve and erasing the limits of the lateral rectus muscle. The orbital magnetic resonance imaging (MRI) showed an intra-conal fusiform mass with an heterogeneous signal in T1 and T2, heightening intensely and heterogeneously after the injection of Gadolinium. Otherwise, the patient presented with an associated respiratory failure, and thoracic CT has disclosed diffuse metastases. It was then noted that a cutaneous melanoma of the left foot had been operated ten years before. The patient died during the following month., Discussion: The cutaneous melanoma is a rare cause of orbital metastasis. The diagnosis is often easy, when a primitive tumor is known, but it remains uncertain for a long time., Conclusion: Orbital metastases from cutaneous melanoma are rare, generally occurring at the late stage of the disease with a life expectancy not passing one year.

Introduction: Vitreous hemorrhage is a frequent complication of proliferated diabetic retinopathy. Vitrectomy has vastly improved its prognosis. The purpose of this study was to evaluate the use of silicone oil in vitreal surgery in this indication., Methods: We present a retrospective study of 15 eyes that underwent vitrectomy and silicone oil injection for vitreal hemorrhage complicating proliferative diabetic retinopathy. For each patient, we noted the clinical and echographic features, the surgical procedure, and the postoperative outcome after a mean period of 20 months., Results: The indications for silicone injection were recurrent vitreal hemorrhage (seven eyes), aggressive fibrovascular proliferations (five eyes), and iatrogenic retinal breaks (three eyes). Anatomic success was noted in ten cases. Four patients had a hemorrhage reoccurrence after silicone oil removal and one patient developed neovascular glaucoma. Silicone cataract (seven eyes) and emulsification of silicone (one eye) were noted., Discussion: The use of silicone oil in vitreal surgery for complicated proliferated diabetic retinopathy contributes a hemostatic and plugging effect, but it still has a number of disadvantages such as the need to remove it and its own side effects. It can be beneficial in cases of rubeosis or recurrent hemorrhage. However, it is essentially indicated in recurrent hemorrhage in monophthalmos patients.

Fibromatosis of the breast is an uncommon benign disease that mimics carcinoma clinically as well as radiographically. Its microscopic diagnosis among spindle cell tumors is fundamental, especially on frozen sections. We report two cases of mammary fibromatosis observed in young woman (26 and 31 years old). The two were clinically and mammographically suspect. Diagnosis was made on frozen sections and confirmed on paraffin embedded specimen. The lesions are characterized by spindle cell proliferation of variable cellularity and collagenization. Few mitotic figures were present in one case. Several lesions must be considered in the differential diagnosis of mammary fibromatosis. Wide local excision is recommended for initial therapy, but local recurrence is frequent. In our cases, In spite of apparently complete excision, one patient relapsed.
