As trade and industrial digitalization advance, artificial intelligence (AI), an essential force in the new wave of technological revolution, is increasingly embedded in the bilateral agenda, steering collaboration beyond efficiencydriven “digital coordination” toward more structured and systemic“intelligent co-development.”Building on five decades of mutual trust since the establishment of diplomatic ties, this cooperation not only addresses the practical needs of industrial upgrading and governance transformation but offers a valuable reference for ASEAN countries exploring replicable pathways in the era of digital transformation.展开更多

Coloboma can affect the adnexa and/or the eyeball. We report the iconography of two cases of ocular colobomas and one case of eyelids coloboma at the IOTA CHU. Case 1: This was a 32-year-old patient who consulted for decreased visual acuity in the left eye. The clinical examination found visual acuity of 10/10 in the right eye and hand movement in the left eye. Biomicroscopic examination revealed an iris and chorioretinal coloboma encompassing the papilla. Case 2: This was a 3-year-old child. Who consulted for eyelid malformation since birth. On ophthalmological examination, there was a bilateral coloboma of the inner half of the upper eyelid, associated with an underlying symblepharon and left eye corneal dystrophy. Our course of action consisted of a release of the symblepharon followed by a blepharoplasty which allowed a good anatomical and functional restitution. Case 3: This was a 15-year-old patient who consulted for bilateral visual acuity loss measured by counting fingers at 1m in the right eye and counting fingers at 3m in the left eye. The biomicroscopic examination found a bilateral papillary coloboma associated with a bilateral progressive cataract, an old detachment of the left retina. The etiological assessment was unremarkable. Conclusion: Coloboma is a congenital condition that can affect all parts of the eye. We reported three cases of colobomas, one palpebral, one iris and chorioretinal, and finally, one papillary associated with other ocular pathologies.展开更多
