Introduction: Peripheral facial palsy (PFP) is a frequent reason for ENT consultations. It is a common complication of human immunodeficiency virus (HIV) infection. The aim of this study was to describe the diagnostic and therapeutic aspects and to establish the correlation between PFP and HIV in our context. Patients and Method: This was a retrospective descriptive study conducted in the ENT and CFS department of the HIAOBO, covering the medical records of patients hospitalized for taking a PFP on HIV terrain from January 1, 2016 to December 31, 2020. Results: The study involved 17 patients, 10 men (59%) and 7 women (41%), a sex ratio of 1.4. The average age was 39 years with the extremes of 11 and 69 years. Shopkeepers reported 9 cases (53%). The reason for consultation was facial asymmetry in 11 cases (100%). The delay in consultation during the first week was 82.4%. Clinical signs were unilateral facial asymmetry, the opening of the palpebral fissure and lacrimation. All patients received medical treatment for PFP and HIV. Evolution was favorable, with complete recovery and no sequelae in 82.4% of cases. Surgery was performed in one case. Conclusion: PFPs are common in HIV infection. Diagnosis is clinical and management is multidisciplinary. Progression depends on the length of time taken to treat the disease.

We report the clinical observation of an HIV-positive/AIDS patient with bilateral macular hemorrhage, which resulted in the identification of severe thrombocytopenia. Thrombocytopenia is a common hematologic anomaly during HIV infection. Its frequency increases with the decrease in CD4 T lymphocytes and the passage to the AIDS stage. Its pathophysiology in this context is complex and multifactorial. Hemorrhagic complications usually appear for platelets less than 50,000/mm3 and this risk is greater at a rate of less than 20,000/mm3. Retinal hemorrhages may go unnoticed, only macular localization results in clinical expression. OCT is of paramount importance in accurate topographic diagnosis of macular hemorrhages by locating their seats which can be pre, intra or under retinal. Management requires the balance of infectious and hematologic factors. Ophthalmic surgical treatments should be considered in a second step.

Introduction: Leukocoria, a whitish pupillary reflection, is a common warning sign of various pediatric ocular pathologies, including Persistent hyperplastic primary vitreous (PHVP). This case report describes the observation of a 3-year-old child with melanoderma, presenting with a white spot in the left eye since birth. Observation: Uncorrected distance visual acuity was 2/10 in the right eye and hand movements were perceived at 2 meters in the left eye. Examination of the anterior segment in the left eye revealed leukocoria and microphthalmia. The fundus examination was normal in the right eye but revealed a white mass extending from the center of the optic disc towards the temporal region in the left eye. Ocular imaging, including ocular ultrasound and optical coherence tomography, confirmed the diagnosis of PHVP, illustrated by a residual white mass at the center of the optic disc in the left eye. Conclusion: PHVP should be considered in the presence of leukocoria in a child, with urgent exclusion of retinoblastoma. This observation underscores the importance of early diagnosis for appropriate management. .

Introduction: Congenital optic disc anomalies in children refer to structural variations of the optic nerve head present from birth. These deformations involve the size, shape, color, and vessels of the optic disc. Although often asymptomatic, these anomalies can impact the visual development of the child, underscoring the importance of a thorough fundus examination for early detection and appropriate medical follow-up. We present two cases of congenital optic disc anomalies in children, illustrating the diagnostic challenges and complexity of their management. Case 1: A 3-year-old girl presented with a white spot in her left eye present since birth. Uncorrected distance visual acuity was 2/10 in the right eye, while she could perceive hand movements at 2 meters with the left eye. Normal examination in the right eye showed leukocoria, microphthalmia, and a white mass at the center of the optic disc on fundus examination in the left eye. Ocular imaging, including ultrasound and optical coherence tomography (OCT), confirmed the diagnosis of persistent hyperplastic primary vitreous (PHPV) in its mixed form in the left eye. Management included prescribing full optical correction and functional rehabilitation, without resorting to surgery. The course was marked by persistent amblyopia leading to a poor prognosis. Case 2: A 7-year-old girl consulted for vision disturbance in her right eye. Visual acuity was finger counting at 2 meters in the right eye and 10/10 in the left eye. Anterior segment examination revealed no abnormalities in both eyes. However, fundus examination highlighted a large funnel-shaped excavation associated with central glial proliferation, wheel spoke vessels, and neuroretinal ring atrophy in the right eye. Optical coherence tomography (OCT) of the right eye confirmed the diagnosis of isolated unilateral Morning Glory syndrome. Management included full optical correction and orthoptic rehabilitation. The course was marked by the absence of ocular com

Introduction: Diabetes represents a major public health challenge, affecting over 463 million people according to the World Health Organization (WHO). Among its complications, diabetic retinopathy stands out as the leading cause of blindness in industrialized countries. Physical activity is now recognized as a cornerstone of diabetes management, and its impact on diabetic retinopathy is of growing interest. Observation: Mr. A.E, a 54-year-old man, presents with progressive deterioration of his vision. Family history of diabetes and hypertension is noted. He engages in one hour of physical activity daily, including treadmill running and indoor cycling. Despite recent optical correction, his visual acuity remains at 3/10 unimproved. Ocular imaging, notably fluorescein retinal angiography and optical coherence tomography, reveals proliferative diabetic retinopathy with bilateral macular edema. Blood tests, performed after physical activity, show normal values of blood glucose and HbA1c, delaying the initiation of treatment and promoting the progression of retinopathy. Despite appropriate management, no significant improvement in visual function is observed during follow-up. Conclusion: The management of diabetic retinopathy requires an approach integrating physical activity. A better understanding of the interaction between physical activity and diabetic retinopathy is needed to optimize prevention and treatment strategies.

Introduction: Morning Glory Syndrome (MGS) is a rare anomaly of the optic nerve characterized by a flower-shaped excavation in the optic disc. This anatomical peculiarity is of growing interest due to its impact on vision and the therapeutic challenges it presents. Despite research advances, gaps persist, requiring thorough exploration to better understand this rare condition. We present the case of a young girl. Observation: A 7-year-old girl presented with persistent deterioration of vision in the right eye since birth. Visual acuity was counting fingers at 2 meters in the right eye and 10/10 in the left eye. Biomicroscopy was normal in both eyes, and fundus examination revealed a funnel-shaped excavation at the optic disc of the right eye, associated with central glial proliferation, thin blood vessels in a radial distribution, and atrophy of the neuroretinal rim. Additional tests confirmed the diagnosis of isolated unilateral Morning Glory Syndrome in the right eye. Combined treatment included appropriate optical correction and functional rehabilitation. Regular ophthalmological follow-up over a one-year period was established to monitor visual acuity evolution, optic disc stability, and detect any potential complications. The reserved prognosis was marked by the absence of ocular complications and maintenance of initial visual acuity in the right eye. Conclusion: The positive response to management underscores the importance of an integrated approach, early diagnosis, therapeutic adherence, and personalized strategies.
