Methods: We retrospectively reviewed the clinical record of 62 patients who underwent external DCR for NLDO between November 2015 and November 2019 at CHU-IOTA in Mali. The preoperative clinical findings and the postoperative outcomes after a minimum follow up of 3 months were analyzed. Results: epiphora, discharges and canthal swelling were main symptoms of the 62 patients (68% women, 32% men), with the mean age of 47 years (10 - 76). Among them, 36 had chronic dacryocystitis, 12 had a traumatic NLDO and 8 followed a septal deviation. The majority (77%) were operated on under local anesthesia with sedation. Bicanalicular intubation was performed in 29% of patients. After postoperative follow up of at least 3 months, only 8 patients had persistent watering, thus a subjective functional success of 87%. Conclusion: In the nasolacrimal duct obstruction, most often secondary to chronic dacryocystitis, external dacryocystorhinostomy remains a technique of choice with very good success.展开更多

Optic nerve meningiomas are histologically benign tumors whose severity is linked to diagnostic and especially therapeutic difficulties. The Optic nerve meningioma is the second leading cause of optic nerve tumor after glioma. Observation: We report the case of a 49-year-old woman from South Asia, who consults an ophthalmology department for progressive visual loss in her right eye for about a year with her glasses and would like to renew her optical correction. Having no particular medical history apart from left unilateral blindness is known for approximately 15 years. Magnetic Resonance Imaging (IRM) cerebral found a tissue mass with a clear outline and polylobules on the left temporo-peduncular. Through this case, we describe the circumstances of discovery of the disease, the clinical characteristics, as well as our diagnostic approach. Conclusion: In the majority of cases, these are benign tumours, the circumstances of which are discovered in multiple ways. A mostly unilateral and non-improvable loss of visual acuity must attract our attention. Renewing glasses may be the reason for discovering the disease. Today Magnetic Resonance Imaging (IRM) remains an important and capital examination for the diagnosis and monitoring of this pathology.展开更多
