Objective To evaluate different methods in determ ining the postoperative changes of anatomical structures in macular diseases. Methods Thirty-one eyes of 31 cases of macular diseases, were studied among them there were 15 eyes with idiopathic macular hole (IMH),and the others included 8 eyes with macular epiretinal membranes(ERMs), 4 eyes with age relate d macular degeneration(AMD) and 4 eyes with idiopathic submacular neovasculariza tions(SRNV). All cases were examined with retinoscope or retinogra phy, fundus fluorescein angiography (FFA) and optical coherence tomography (OCT ) pre-and postoperatively. Results Funduscopy showed that all of the 15 IMHs were closed after operation, but OCT showed th at among them 2 affected eyes still had partial retinal detachment at the macular hole edge in one quadrant and the sensory layer in macular area became thinner in 1 affected eye. FFA revealed damage of retinal pigment epithelium (RPE) in 5 cases. As for the ERMs and SRNV, funduscopy could n ot identify wether they were completely removed or not after operation. FFA ind icated that SRNV and SRNV were completely removed and the damage of RPE.OCT discovere d that the ERMs and SRNV were completely removed and the sensory layer became th inner in 3 eyes. Conclusion The combination of funduscopy , FFA and OCT can get the whole view of macular diseases and their postopera tive anatomical evaluation. (Chin J Ocul Fundus Dis, 2001,17:33-36)
The threshold micropulse laser is widely used in clinical practice as a safe, non-invasive laser for avariety of macular diseases. Compared with the conventional laser therapy, the subthreshold micropulse laser is selectively absorbed by the RPE and therefore it does not cause retinal damage. To explore the therapeutic mechanism and the safety, development of threshold micropulse laser in the treatment of various common macular diseases, and further clarify its indications and advantages, which are helpful for its wider clinical application.
The macula is a critical anatomical structure for primates to acquire high-resolution spatial and color vision, with macula lesions posing a significant threat to patients' visual function and quality of life. Non-human primate (NHP) are the only mammals with a macular structure that is closest to that of humans, thus offering substantial value in the study of macular diseases. Currently, various methods, including spontaneous occurrence, gene editing, drug-induced, light-induced, and mechanical injury, can be employed to screen and establish NHP models for investigating conditions such as oculocutaneous albinism, achromatopsia, retinitis pigmentosa, age-related macular degeneration, and certain rare ocular syndromes. When constructing NHP models, due consideration should be given to other animal models to facilitate complementary research across different model systems. Additionally, leveraging the advantages of NHP and establishing genetically controlled NHP strains is a goal to strive for to achieve sustainable utilization of these resources in research.
