Ocular involvement in rheumatic diseases

Rheumatic diseases are associated with a significant decline in quality of life, which is not only related to the progression of the underlying disease but also to the development of coexisting conditions. One of the possible complications in this group of diseases is ocular involvement. Impaired vision is strongly associated with a significant decline in quality of life and can also exacerbate problems related to physical functioning. Consequently, it can lead to serious complications in the treatment of the underlying disease. Additionally, from a clinical point of view, it is also important to note that ocular diseases may precede the occurrence of inflammatory joint and spinal diseases, as well as organ involvement in systemic connective tissue disorders. Therefore, paying attention to ocular symptoms can help in early diagnosis and thus improve patient prognosis. For the aforementioned reasons, ocular diseases should be carefully considered in routine rheumatologic practice.

New Frontiers of Corneal Gene Therapy

Corneal diseases are among the most prevalent causes of blindness worldwide. The transparency and clarity of the cornea are guaranteed by a delicate physiological, anatomic, and functional balance. For this reason, all the disorders, including those of genetic origin, that compromise this state of harmony can lead to opacity and eventually vision loss. Many corneal disorders have a genetic etiology, and some are associated with rather rare and complex syndromes. Conventional treatments, such as corneal transplantation, are often ineffective, and to date, many of these disorders are still incurable. Gene therapy carries the promise of being a potential cure for many of these diseases, with solutions and strategies that did not seem possible until a few years ago. With its potential to treat genetic disease by means of deletion, replacement, or editing of a defective gene, the challenge can also be extended to corneal disorders in order to achieve long-term, if not definitive, relief. The aim of this paper is to review the state of the art of the different gene therapy approaches as potential treatments for corneal diseases and the future perspectives for the development of personalized gene-based medicine.
