“…Two case series reported the application of three-dimensional-FA-guided PPV in addressing PDR and retinal vein occlusion. 29,30 Employing a high-resolution 3D visualization system, surgeons can obtain real-time information on blood flow within the retina and closely examine the peripheral retina, a task that has been challenging with standard FA approaches in outpatient settings. A key benefit of this approach is the immediate access to angiographic data during surgery, a feature not feasible with traditional surgical techniques.…”

“…29 Additionally, when retinal vein occlusion is incidentally discovered during PPV for vitreous hemorrhage, it can be difficult to decide the extent of photocoagulation needed and to fully remove FVPM during surgery. 30 This difficulty arises from the complications inherent in accurately determining the size and orientation of neovascularization and predicting its adhesion to the vitreoretinal interface, particularly in eyes with incomplete posterior vitreous detachment. 3D-FA can help address these issues by verifying the size and location of neovascularization in real time during surgery.…”

Three-Dimensional (3D) heads-up visualization systems have significantly advanced vitreoretinal surgery, providing enhanced detail and improved ergonomics. This review discusses the application of 3D systems in vitreoretinal surgery, their use in various procedures, their combination with other imaging modalities, and the role of this technology in medical education and telementoring. Furthermore, the review highlights the benefits of 3D systems, such as improved ergonomics, reduced phototoxicity, enhanced depth of field, and the use of color filters. Potential challenges, including the learning curve and additional costs, are also addressed. The review concludes by exploring promising future applications, including teleophthalmology for remote assistance and specialist availability expansion, virtual reality integration for global clinical education, and the combination of remotely roboticguided surgery with artificial intelligence for precise, efficient surgical procedures. This comprehensive review offers insights into the current state and future potential of 3D heads-up visualization systems in vitreoretinal surgery, underscoring the transformative impact of this technology on ophthalmology.

“…Finally, vitrectomy is done in severe cases where removal of the vitreous body and its surrounding membrane would stop the bleeding permanently. This procedure is done as a last resort when a cause is not identified, bleeding has not stopped, and vision has not improved as in cases of sickle cell retinopathy and retinal vein occlusion [15,16]. Surgical intervention is also used in syndromic patients, with Terson's or Ehlers-Danlos, who develop unremitting vitreous bleeding [17,18].…”

The retinal vessels may become susceptible to damage due to retinal tear, retinal detachment, sickle cell insult, aneurysms, macular degeneration, trauma, and veinous occlusion. These conditions could cause retinal bleeding, also known as vitreous hemorrhage. PubMed database was used for articles selection, papers were obtained and reviewed. PubMed database was used for articles selection, and the following keys terms: vitreous hemorrhage, pathophysiology, risk factors, clinical features, diagnosis, and management. The vascular insult occurs in the surrounding potential space around the vitreous. This insult is a result of traumatic injury to the retina or the vessels or ischemic condition of the vessels due to an abnormal vessel formation. Immediate diagnosis and management of the bleeding are needed, especially in cases with deteriorating vision and continued bleeding. Management options include watchful waiting, laser therapy, cryotherapy, antivascular growth injections, and vitrectomy. Vitreous hemorrhage is a medical emergency that could lead to severe and permanent visual loss if not diagnosed and managed fastidiously. The disease may often resolve on its own and vision is restored, however, medical and surgical therapy might be urgently required in selected cases.

“…RME is the main cause of severe visual impairment in patients with RVO [10] . Currently, the primary treatments for patients with RVO are vitreous injection, laser photocoagulation, and vitrectomy [11][12][13] . Intravitreal injection of anti-vascular endothelial growth factor (VEGF) drugs can significantly improve visual acuity loss caused by RME [14] , and laser photocoagulation is often performed in patients with intraocular neovascularization [15] .…”

AIM: To develop an artificial intelligence (AI) diagnosis model based on deep learning (DL) algorithm to diagnose different types of retinal vein occlusion (RVO) by recognizing color fundus photographs (CFPs). METHODS: Totally 914 CFPs of healthy people and patients with RVO were collected as experimental data sets, and used to train, verify and test the diagnostic model of RVO. All the images were divided into four categories [normal, central retinal vein occlusion (CRVO), branch retinal vein occlusion (BRVO), and macular retinal vein occlusion (MRVO)] by three fundus disease experts. Swin Transformer was used to build the RVO diagnosis model, and different types of RVO diagnosis experiments were conducted. The model's performance was compared to that of the experts. RESULTS: The accuracy of the model in the diagnosis of normal, CRVO, BRVO, and MRVO reached 1.000, 0.978, 0.957, and 0.978; the specificity reached 1.000, 0.986, 0.982, and 0.976; the sensitivity reached 1.000, 0.955, 0.917, and 1.000; the F1-Sore reached 1.000, 0.955 0.943, and 0.887 respectively. In addition, the area under curve of normal, CRVO, BRVO, and MRVO diagnosed by the diagnostic model were 1.000, 0.900, 0.959 and 0.970, respectively. The diagnostic results were highly consistent with those of fundus disease experts, and the diagnostic performance was superior. CONCLUSION: The diagnostic model developed in this study can well diagnose different types of RVO, effectively relieve the work pressure of clinicians, and provide help for the follow-up clinical diagnosis and treatment of RVO patients.
