High myopia is frequently associated with retinal degenerative changes (such as myopic foveoschisis, macular hole and its related retinal detachment, and choroidal neovascularization) which are the major causes of visual loss in high myopic eyes. Optical coherence tomography may help us to understand the macular lesions in high myopia. Peeling of internal limiting membrane and removal of posterior vitreous cortex at an appropriate time, are believed to facilitate restoring the retinal flexibility and resolution of myopic foveoschisis, and promote the macular hole closure and retinal reattachment. Anti-angiogenesis treatment combined with photodynamic therapy and (or) corticosteroid therapy are the future options to treat myopic choroidal neovascularization. Correctly understanding and mastering the methods and timing of diagnosis and treatment of high myopia-related macular degeneration, and taking targeted interventions to enable patients to be rational and effective treated, are the keys to further reduce the damage of visual function in patients with high myopia.

The molecular weight of matrix metalloproteinase (MMP)-9 is the largest in MMP family which comes mainly from macrophage and neutrophil.MMP-9 is considered to be involved in the occurrence and metastasis of colorectal cancer.It also provides a new way for colorectal cancer in clinical prevention and treatment.

Stickler syndrome is a hereditary connective tissue disorder, characterized in ocular manifestations by high myopia and vitreous abnormalities. The progression of the disease can lead to giant retinal tear and rhegmatogenous retinal detachment, making it the most common cause of inherited pediatric retinal detachment. Surgical intervention is the primary treatment for retinal detachment associated with Stickler syndrome. However, there are currently no evidence-based management strategies. Patients typically require multiple surgeries, with low reattachment rates and high recurrence rates, emphasizing the importance of prophylactic treatment. Current prophylactic measures include scleral bucking, laser photocoagulation and retinal cryotherapy, but their absolute benefits remain insufficiently supported. This review summarizes recent advances in the prophylaxis and treatment of retinal detachment in Stickler syndrome, aiming to provide new insights and essential references for the prevention and treatment for such conditions.
