ppV with subretinal injection of rtPA and intravitreal injection of gas was more effective than ppV with intravitreal injection of rtPA and gas in terms of complete displacement of submacular hemorrhage; however, it may be associated with a higher rate of postoperative complications. Functional improvement in the majority of patients suggests the absence of direct retinal toxicity of subretinally applied rtPA.
Foveal cyst, absent macular oedema, intraretinal hyperreflective lesions and foveal flattening were the most common OCT findings in patients with JRT type II. These may represent progressive loss of retinal tissue, possibly due to Müller cells degeneration, and provide additional diagnostic criteria for JRT.
A case of uncomplicated macular hole surgery including internal limiting membrane peeling and the application of platelet concentrate followed by a presumed subretinal dislocation of the platelets around the macular hole is presented. The exact localization of the deposits could be determined by optical coherence tomography and autofluorescence. During follow-up, the concentric ring formation disappeared, while visual acuity remained stable.
With the help of modern ultrasound examinations we have identified biometric changes in the anterior segment of vitrectomized eyes. We have also established a myopic shift of clinical refraction, which is most likely to be due to the increase in axial eye length and lenticular changes.
Despite the emergence of new approaches in the treatment of retinal vein thrombosis and post-thrombotic complications, namely, intravitreal pharmacotherapy and surgical treatment, laser photocoagulation continues to play a significant role in the management of patients with this pathology. Although the method of laser photocoagulation has been used for quite a long time, different views exist on its indications and execution in specific clinical situations. At that, not all opinions regarding the use of laser photocoagulation in thrombosis are based on convincing clinical studies. The aim of this work was to summarize current literature data on the use of laser photocoagulation in the integrated treatment of retinal vein occlusions and, also, to show which aspects of the treatment of thromboses can be considered well-established and reasonable and which remain a subject of debate.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
