Introduction: Rosai-Dorfman disease (RDD) is a sinus histiocytosis with massive lymphadenopathy. This rare condition is a benign disease of unknown etiology. Bilateral orbital localization of RDD is rare., Observation: The authors report the case of a 6-year-old child who presented with bilateral orbital-palpebral masses associated with chronic cervical lymphadenopathy. There were no laboratory signs of inflammation. Serological and tuberculosis screening tests were negative. Histopathological examination of a lymph node biopsy established a diagnosis of Rosai-Dorfman disease. The patient underwent surgical excision of the orbital lesions followed by long-term corticosteroid therapy. A favorable course was observed, with no sign of recurrence after one year of follow-up., Conclusion: Rosai-Dorfman disease is very rare in its bilateral orbital presentation. Histopathological diagnosis remains challenging. In Africa, the presence of chronic oculo-palpebral tumor associated with or without cervical lymphadenopathy must raise the suspicion of Rosai-Dorfman disease after ruling out tuberculosis and lymphoma., (Copyright © 2024 Elsevier Masson SAS.

Objective: To describe the etiologies, clinical presentation and therapeutic management of neovascular glaucoma (NVG) in Senegalese patients., Patients and Methods: We retrospectively studied the records of patients followed for NVG between 1993 and 2016. We included eyes with Iridis rubeosis with or without ocular hypertension. We recorded age, sex, medical and ophthalmologic history, results of the eye examination, treatment modalities broken up into hospitalisation, procedural interventions and number of antiglaucoma medications prescribed. The data analysis was performed by epi-info 7., Results: Forty-eight eyes of 44 patients were included. The mean age was 59.7 years and sex ratio 2.1. Etiologies were type 2 diabetes in 31.8 % cases and central retinal vein occlusion in 16.6 % cases. All eyes were blind. Eye pain was present in 75 % of eyes, a limbal flush in 29.1 % of eyes and mydriasis in 31.25 % of eyes. Mean intraocular pressure was 49.7mmHg. Corneal edema occured in 54.1 % of eyes. Fundus examination showed proliferative retinopathy in 14.5 %. Treatment required hospitalisation for 43.75 % of patients. Therapeutic procedures were cyclocryoapplication for 31.25 % of eyes, retrobulbar xylo-alcohol injection for 14.5 % of eyes and panretinal laser photocoagulation (PRP) for 12.5 % eyes. Antiglaucoma preparations were used in dual therapy for 29 % of eyes, in triple therapy and quadruple therapy for 25 % of eyes each., Discussion: The etiologies are comparable to those described in the literature. The diagnosis was late and treatment limited by adverse economic conditions., Conclusion: NVG in Senegalese patients is an affection of men in their sixties. It is responsible for irreversible painful blindness for which treatment is difficult - thus the interest in prevention by strict monitoring and prompt treatment of any retinal ischemia., (Copyright © 2018 Elsevier Masson SAS.

Introduction: The aim of this work is to identify the main weapons causing eye injuries during the campaigns of the Senegalese army in the south of the country, as well as the prognosis of these traumas., Patients and Methods: This study is retrospective and concerns soldiers wounded by the weapons of war during the exercise of their mission within the Senegalese armed forces of 1991 in 2005. They are mainly soldiers affected in the south of the country during a war, clashes with the rebels or in Guinea-Bissau during operation Gabou in 1998. And they were evacuated to the ophthalmology department of the Principal Hospital in Dakar, which is a level 3., Results: Thirty-seven military all male, with an average age of 30.5 years. Forty-six eyes including 9 bilateral cases. The trauma agent is a burst of RPG7 shells in 62% of cases, mine explosion in 13.5%, offensive grenade 10.8%, assault rifle 5.7% and flame lance-roquette anti-char (LRAC) accounts for 8%. We noted a phthisis of the globe for 14 eyes (30.43%) and for 15 eyes (32.60%) a functional loss of the affected globe. Inability to fight was decided by 29 wounded soldiers (78.37% of the cases), sedentary employment in 27 cases (72.97%) and 10 cases (27.03%) of reformed soldiers., Discussion: In the conflict in southern Senegal, the RPG7 shell burst causes 62% of eye injuries. This RPG7 shell called "rebel weapon" is frequently used in conflicts in Africa. The prognosis of trauma with these types of weapons is severe., Conclusions: The combat goggles systematically integrated in the equipment of the Senegalese combatant, would be an invaluable contribution on the prevention of the traumatisms of the eye., (Copyright © 2016 Elsevier Masson SAS.

Introduction: The purpose of our study was to evaluate in the short and medium term, intraocular pressure results after selective laser trabeculoplasty in black patients with chronic open angle glaucoma or isolated ocular hypertension., Materials and Methods: We conducted a retrospective study with a mean 12.5-month follow-up in black patients who underwent SLT. Inclusion criteria were: an open iridocorneal angle greater than or equal to Schaeffer grade 3, data recorded and available on trabecular pigmentation, data on SLT parameters available, and intraocular pressure by Goldmann applanation tonometry recorded.A positive result was defined as a post-laser IntraOcular Pressure (IOP) less than 21 mmHg after 1-month follow-up. The main motivation was the reduction of number of eye drops used. Performed first was a treatment of the inferior 180° (3:00-9:00), possibly supplemented by a second session at 15 days or 1 month if a pressure decrease was noted after the first session. IOP results were evaluated prior to SLT, immediately following SLT and then depending on the drop in pressure. Statistical analysis was performed using the EPI.info 7 software., Results: A total of 69 eyes of 40 patients treated with SLT were identified. The mean IOP prior to SLT was 18.3 mmHg ± 4. Our results showed 90% of patients who positively responded to the treatment (10% failure) with a mean IOP decrease of 2.3 ± 1 mmHg, that is 13%, by the second week. The mean pressure decrease continued to 4.78 ± 1 mmHg for patients (30%) in the group treated for 360°, that is 27% in the same period of time. SLT permitted discontinuation of a prostaglandin in 60% (42 cases). Eyes on triple-drug therapy went from 23 before SLT to 5 following SLT (a 26% decline), eyes on two medications went from 32 to 16 (24% decline). In result association tests, only pigmentation of the angle and visual field stage had a statistically significant probability., Discussion: In our experience, SLT is indicated in black patients to potentiate less effective treatments, to reduce the number of drops in order to limit side effects, but also to avoid or delay monotherapy treatment-naïve, hypertensive eyes., Conclusion: In the short and medium term, SLT brought about an IOP decrease in 90% of black patients, and discontinuation of a prostaglandin in 60% of our patients. In addition, the iridocorneal angle in blacks appears to be less pigmented than previously thought, and a protocol systematically treating 360° seems to provide better results., (Copyright © 2014 Elsevier Masson SAS.
