[Profile of neovascular glaucoma in Senegalese patients]. / Profil du glaucome néovasculaire chez les patients sénégalais.

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.

[Etiology and prognosis of the eye traumas by war weapons in the Senegalese army]. / Étiologies et pronostic des traumatismes oculaires par armes de guerre dans l'armée sénégalaise.

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.

[Selective laser trabeculoplasty (SLT): our experience in African blacks]. / La trabéculoplastie au laser sélectif (TLS) : notre expérience chez le noir africain.

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.

[Epidemiological and clinical characteristics of primary ocular cancers in blacks: our experience with 111 cases]. / Aspects épidémiologiques et cliniques des cancers oculaires primitifs du mélanoderme : notre expérience à propos de 111 cas.

INTRODUCTION: In this work, the authors aim to study clinical and epidemiological characteristics of ocular and orbital primary cancers in sub-Saharan African. PATIENTS AND METHODS: This is a retrospective study over a period of 21 years, from 1984 to 2004, including all cases of ocular cancer, histologically proven after surgery of the globe or the orbit. For each patient, we studied the following parameters: age, sex, reason(s) for consultation, the affected eye, and histological result of the operative specimen. These data were collected by studying the departmental surgical registry, patient medical records and the tumor registry of the anatomicopathology laboratory of a tertiary care hospital in sub-Saharan Africa. RESULTS: We collected data on 111 black patients, among whom 15 cases (13.5%) presented with bilateral involvement, for a total of 126 eyes. The sex ratio was 1.17. Presenting signs showed a predominance of leukocoria (30.2%) followed by proptosis (21.7%) and in third place, protruding conjunctival mass (10.8%). Retinoblastoma was found most frequently, representing 66.6% of the oculo-orbital tumors and 95.45% of the tumors of the globe; followed by epidermoid carcinoma, representing 15.08% of cases. Malignant melanoma was third most common, representing 4.76%, with 83% arising in the anterior uvea and 7% in the choroid. Basal cell carcinoma and rhabdomyosarcoma follow in fourth place. Basal cell carcinoma constituted half (50%) of the eyelid tumors. Rhabdomyosarcoma was the most common orbital tumor in our series (57%). Next were lymphomas with conjunctival localization (2.38%), acute leukemia with orbital localization (1.59%) and rare tumors, palpebral dermatofibrosarcoma (0.79%), an orbital angiosarcoma (0.79%), a glioblastoma of the globe (0.79%) and a malignant solitary fibrous tumor of the orbit (0.79%). CONCLUSION: Ocular and orbital primary cancers in blacks remain tumors of the young, equally distributed between the sexes. Retinoblastoma is the most frequent, followed by epidermoid carcinoma. The globe is the preferential localization of these cancers.

[Central corneal thickness in Senegalese melanoderms with primary open angle glaucoma]. / Épaisseur cornéenne centrale chez le mélanoderme sénégalais atteint de glaucome primitif à angle ouvert.

PURPOSE: To measure the central corneal thickness (CCT) in Senegalese melanoderms with primary open angle glaucoma (POAG) and to determine its effect on visual impairment, intraocular pressure, optic nerve and perimetric damage. PATIENTS AND METHODS: We studied retrospectively the records of patients followed for POAG between May and July 2012. We recorded CCT measured by ultrasonic pachymetry and results of the first clinical examinations, including best-corrected visual acuity (CVA), intraocular pressure (IOP) by Goldmann tonometry, cup-to-disc ratio (C/D), and visual fields by automated perimetry according to the classification of Hodapp. RESULTS: Two hundred and thirty-four eyes of 117 patients were enrolled. Mean age was 56.53 ± 11.29 years and gender ratio was 2.77. Mean CCT was 525.40 ± 39.63 µm for all eyes, right and left (P=0.734). Women had a mean CCT of 521.20 ± 36.20 µm and men 526.91 ± 40.79 µm (P=0.332). Corneas were thinner in patients over 50 years (P=0.0047), in eyes having a CVA<3/10 (P=0.01) or a C/D ≥ 0.8 (P=0.043). CCT had no correlation with frequency of ocular hypertension (P=0.16) or advanced visual field defect (P=0.33). CONCLUSION: CCT of glaucomatous Senegalese is independent of laterality and sex, but decreased with age. A thin cornea is a risk for visual loss and optic cup enlargement, thus the importance of systematic measurement of CCT.

[Orbital mycetoma: a case report]. / Mycétome orbitaire : à propos d'un cas.

INTRODUCTION: Mycetomas are pathological processes through which exogenous fungal or actinomycotic etiological agents produce grains. These etiological agents live in the soil and plants of endemic areas. They are introduced traumatically, primarily into the foot. The orbital location is rare. OBSERVATION: We report the case of a 17-year-old student admitted for progressive left proptosis over 2 years, following penetrating trauma by a fork in a rural setting. Examination revealed a heterogenous orbital mass with multiple fistulae, producing pus and black grains, and suggested, due to the color of the grains, a diagnosis of fungal mycetoma. MRI revealed a destructive process at the level of the lamina papracea of the ethmoid and the orbital floor. Anatomopathological examination confirmed the fungal nature of the infection, while culture in Sabouraud's medium was inconclusive. The outcome was favorable after exenteration and debridementof the ipsilateral maxillary sinus and nasal cavities, along with 4 months of ketoconazole. No recurrence has been observed for 14 months after surgery. DISCUSSION: Mycetomas are endemic to northwest Africa. Most frequently located in the foot, they are seldom seen in the orbit. The color of the grains provides a clue as to the etiology. Black-grain mycetomas are always fungal and are treated surgically--essentially like cancer--as the persistence of a single grain will cause a recurrence. CONCLUSION: The orbital location of a mycetoma is rare. In the present case report, the concept of port of entry, the clinical appearance, and the color of the grains guided the diagnosis. The histological examination of the surgical specimen confirmed the diagnosis.
