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.展开更多

In Gabon, 10% of the population is affected by this condition, highlighting the need to actively understand and manage it. Ocular complications of diabetes, including diabetic retinopathy, glaucoma, and cataracts, have a devastating impact on patients quality of life and represent a crucial issue for healthcare systems. Methodology: This study conducted in Libreville from February 9, 2022, to April 15, 2022, was cross-sectional, longitudinal, and descriptive, with prospective data collection. Participants were diabetic patients regularly followed in the endocrinology department of CHUL, who were referred for a comprehensive ophthalmological examination at CHUO. Sampling was exhaustive, with strict inclusion criteria aimed at ensuring the representativeness of the study population. Results: The mean age of participants was 57.5 ± 13.2 years with a male-to-female ratio of 0.8. Personal histories were dominated by hypertension, while family histories were dominated by diabetes. Ocular complications of diabetes included refractive disorders (78.9%), cataracts (31.7%), glaucoma (78.9%), and diabetic retinopathy (13.7%). These ocular complications had a significant impact on participants’ quality of life, leading to impaired vision (78.9%), difficulties in carrying out daily activities (62.2%), the need for caregiver assistance (50.3%), high levels of stress and anxiety (68.9%), regular medication intake (71.4%), adherence to a specific diet (55.9%), and frequent blood glucose monitoring (74.5%). Conclusion: This study highlights the major impact of diabetic ocular complications on patients’ quality of life.展开更多

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 complication and maintenance of visual stability in the right eye. The prognosis seemed favorable. Conclusion: Congenital optic disc anomalies in children exhibit great clinical variability and require an individualized diagnostic and therapeutic approach.展开更多

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.展开更多
