RESUMO
Charles Bonnet syndrome(CBS)refers to hallucinations resulting from visual pathway damage in individuals without neuropsychiatric disorders. CBS patients typically have insight into the unreality of their hallucinations, and the disorder may be episodic, periodic, or chronic. The condition's prevalence varies from 0.4% to 30% due to the absence of agreed diagnostic criteria for CBS and some patients' reluctance to acknowledge hallucinations. Massive studies have demonstrated an association between CBS and ocular diseases, such as age-related macular degeneration and glaucoma. Additionally, there have been reports of CBS occurring after ophthalmic surgery or medication. Therefore, clinicians should be vigilant in diagnosing CBS promptly and reassuring patients. There is a lack of literature on CBS in ophthalmology, and further research is needed to explore its pathogenesis and diagnostic and therapeutic options. This article reviews some of the studies related to CBS in recent years.
RESUMO
@#Retinitis pigmentosa(RP)was known as pigmentation retinitis even. RP is a group of hereditary eye diseases that cause irreversible visual impairment due to progressive loss of function of retinal pigment epithelial cells and progressive apoptosis of photoreceptors. Because of its heterogeneity in phenotype and heredity and complex pathogenesis, there is currently no single effective treatment. This article mainly elaborates on the progress in the treatment of retinitis pigmentosa in recent years.
