2. Retinal detachment after acute posterior vitreous detachment resulting from posterior chamber phakic intraocular lens implantation. (PubMed)

Retinal detachment after acute posterior vitreous detachment resulting from posterior chamber phakic intraocular lens implantation. A 39-year-old woman presented with an early posterior vitreous detachment (PVD) after the implantation of an Implantable Collamer Lens phakic intraocular lens (pIOL). The patient detected PVD, noticing metamorphopsia early after surgery; it was confirmed with optical coherence tomography 5 days postoperatively. She was examined by a retinal expert, and no retinal (...) tears were found. However, 15 days postoperatively, the patient had a retinal tear; 38 days later, a retinal detachment (RD) occurred despite treatment with argon laser photocoagulation. Prompt treatment and adequate patient cooperation achieved a final good uncorrected distance visual acuity (20/20). To our knowledge, this is the first description of the whole sequence involving early PVD leading to RD after pIOL implantation. This case highlights the importance of a fundus examination before

3. Central retinal artery occlusion during vitrectomy: Immediate retinal revascularization following induction of posterior vitreous detachment (PubMed)

Central retinal artery occlusion during vitrectomy: Immediate retinal revascularization following induction of posterior vitreous detachment To describe a patient with acute central retinal artery occlusion (CRAO) during vitrectomy surgery and the possible role of vitrectomy in acute CRAO management.An 84-year-old man presented with broad vitreomacular traction and epiretinal membrane in the right eye. Preoperative assessment clearly showed normal retinal vasculature. On starting vitrectomy (...) , complete CRAO with marked segmentation of all retinal vessels was noted. Vitrectomy was performed in the usual manner and once the posterior hyaloid detached from the disc, immediate complete revascularization of the retinal vessels was noted. The patient had a complete visual recovery.Immediate vitrectomy with induction of posterior vitreous detachment may have a role in selected cases of acute CRAO, particularly if performed within a short window.

12. Posterior Vitreous Detachment and the Posterior Hyaloid Membrane. (PubMed)

Posterior Vitreous Detachment and the Posterior Hyaloid Membrane. Despite posterior vitreous detachment being a common ocular event affecting most individuals in an aging population, there is little consensus regarding its precise anatomic definition. We investigated the morphologic appearance and molecular composition of the posterior hyaloid membrane to determine whether the structure clinically observed enveloping the posterior vitreous surface after posterior vitreous detachment is a true (...) basement membrane and to postulate its origin. Understanding the relationship between the vitreous (in both its attached and detached state) and the internal limiting membrane of the retina is essential to understanding the cause of rhegmatogenous retinal detachment and vitreoretinal interface disorders, as well as potential future prophylactic and treatment strategies.Clinicohistologic correlation study.Thirty-six human donor globes.Vitreous bodies identified to have posterior vitreous detachment were

13. Posterior Vitreous Detachment as Observed by Wide-Angle OCT Imaging. (PubMed)

Posterior Vitreous Detachment as Observed by Wide-Angle OCT Imaging. Posterior vitreous detachment (PVD) plays an important role in vitreoretinal interface disorders. Historically, observations of PVD using OCT have been limited to the macular region. The purpose of this study is to image the wide-angle vitreoretinal interface after PVD in normal subjects using montaged OCT images.An observational cross-sectional study.A total of 144 healthy eyes of 98 normal subjects aged 21 to 95 years (51.4 (...) to the periphery (12 eyes, mean age 67.9±8.4 years); stage 3, peripapillary PVD with persistent vitreopapillary adhesion alone (7 eyes, mean age 70.9±11.9 years); stage 4, complete PVD (35 eyes, mean age 75.1±10.1 years). All stage 1 PVDs (100%) were observed in the paramacular to peripheral region where the vitreous gel adheres directly to the cortical vitreous and retinal surface. After progression to stage 2 PVD, the area of PVD extends posteriorly to the perifovea and anteriorly to the periphery

14. Posterior Vitreous Detachment Precipitated by Yoga (PubMed)

Posterior Vitreous Detachment Precipitated by Yoga Yoga has recently been touted as a means to improve physical and mental well-being. However, no form of exercise is without its risks. A 32-year-old Chinese female with moderate myopia complained of right eye sudden onset of floaters and mild blurring of vision after the head-down posture. The visual acuity was 6/12 in the right eye and 6/9 in the left eye. A right eye fundus examination showed posterior vitreous detachment, with a small blood (...) clot located at the inferior margin of the optic disc. The patient was diagnosed with right eye vitreous hemorrhage secondary to acute posterior vitreous detachment and was managed conservatively. Acute changes in posture, especially between an upright and a head-down position, may cause acute posterior vitreous detachment. As yoga practitioners may be required to assume this head-down position, myopic patients should be warned of the possible ocular complications of this exercise.
