Alzheimer’s disease and Parkinson’s disease are the most prevalent neurodegenerative disorders, with AD being diagnosed by memory impairment and PD being manifested by loss of motor function[1] . These diseases are found to be associated with the pathological changes in the retina. Patients with Alzheimer’s disease clinically present with weakening of retinal vasculature, thinning in the retinal nerve fiber layer, and the ganglion cellinner plexiform layer. A decrease in retinal perfusion density, vessel density, and choroidal vascularity index has been observed in patients with Parkinson’s disease. The time-consuming manual segmentation of the vasculature is now replaced with the use of advanced artificial intelligence (AI)-based models that aid in the vasculature segmentation and particularly in the decision making of ophthalmologists for the ultimate diagnosis[2,3] . This article aligns with the TITAN Guidelines on the need for transparency in AI use in healthcare[4] .  \nThe application of AI-powered oculomics, such as deep learning and machine learning, has enabled the prediction of multiple neurodegenerative diseases. These diagnostic measures from AI allow the initiation of early preventive measures that reduce morbidity and mortality[5] . The onset of more severe symptoms can also be avoided with medications in the early stages. Retina, being a valuable window into the brain, can reflect neurodegenerative processes. AD is associated with thinning of the retinal nerve fiber layer and reduced contrast sensitivity due to loss of dopaminergic retinal cells, which has been observed in PD. Asa rapidly emerging transformative technology, AI has the  \naDepartment of Medicine, King Edward Medical University, Lahore, Pakistan,  \nbDepartment of Medicine, Faisalabad Medical University, Faisalabad, Pakistan, cDepartment of Medicine, Jinnah Sindh Medical University, Karachi, Pakistan and dDepartment of Medicine, Sir Salimullah Medical College, Dhaka, Bangladesh Sponsorships or competing interests that may be relevant to content are disclosed at the end of this article.  \n*Corresponding author.
