The retinal Schiff base is a chromophore of significant biological relevance, as it is responsible for capturing sunlight in rhodopsins, which are photoactive proteins found in various living organisms. Additionally, this chromophore is subjected to various mechanical forces in different proteins, which alter its structure and, consequently, its properties. To thoroughly understand the mechanical response limits of the retinal excitation energy, a simple first-order formalism has been developed to quantify the chromophore's optimal mechanical response to applied external forces (on the order of tens of pN).

Retin Cases Brief Rep
January 2025
Department of Ophthalmology, American University of Beirut, Beirut, Lebanon.
Purpose: To report a successful case of vision restoration and macular reperfusion following branch retinal artery occlusion (BRAO) using pars plana vitrectomy with undermining the artery off the retinal bed.
Methods: This case report involves a 75-year-old patient who was diagnosed immediately with BRAO following cardiac catheterization procedure. An embolus at the superior retinal artery bifurcation was noted.

Subretinal injection of gene products is the only treatment option for inherited retinal diseases. However, this procedure induces localized high multiaxial deformations, potentially causing irreversible tissue damage due to retinal overstretching and tearing. Comprehensive characterization of retinal mechanical behavior is essential for performing safe injections.
