Article Abstract

The intricate interaction network necessary for essential physiological functions underscores the interdependence among eukaryotic cells. Mitochondria-Associated Endoplasmic Reticulum Membranes (MAMs), specialized junctions between mitochondria and the ER, were recently discovered. These junctions participate in various cellular processes, including calcium level regulation, lipid metabolism, mitochondrial integrity maintenance, autophagy, and inflammatory responses via modulating the structure and molecular composition of various cellular components. Therefore, MAMs contribute to the pathophysiology of numerous ocular disorders, including Diabetic Retinopathy (DR), Age-related Macular Degeneration (AMD) and glaucoma. In addition to providing a concise overview of the architectural and functional aspects of MAMs, this review explores the key pathogenetic pathways involving MAMs in the development of several ocular disorders.

Background: Stickler syndrome (STL) is a group of related connective tissue disorders characterized by heterogeneous clinical presentations with varying degrees of orofacial, ocular, skeletal, and auditory abnormalities. However, this condition is difficult to diagnose on the basis of clinical features because of phenotypic variability. Thus, expanding the variant spectrum of this disease will aid in achieving a firm definitive diagnosis of STL.
