PURPOSE: Contrast sensitivity function (CSF) declines with age. When unassociated with cataracts, this is hypothesized to be due to macular ganglion cell complex (GCC) thinning. However, other studies found associations with increased vitreous echodensity and posterior vitreous detachment (PVD). We investigate the relationship between CSF, vitreous echodensity, PVD, and GCC thickness as related to age in the same subjects. METHODS: Age, CSF (Weber index: %W), vitreous echodensity (quantitative ultrasonography [QUS]), lens status (phakia or pseudophakia), best-corrected visual acuity (BCVA), and GCC thickness (SD-OCT) were evaluated in 57 eyes of 57 subjects with (n = 32, mean age = 62 years) and without (n = 25, mean age = 44 years) PVD (P < 0...

PURPOSE: To examine frequency and associations of retinal hemorrhages. METHODS: The population-based Beijing Eye Study included 3,468 individuals. Monoscopic fundus photographs were examined for hemorrhages. RESULTS: Retinal hemorrhages were detected in 515 eyes (429 individuals) (prevalence: 7.6%; 95% confidence interval [CI]: 7.0-8.0 per eye; 12.7%; 95% CI: 11.7-13.7 per person). Higher prevalence of retinal hemorrhages was correlated (multivariate analysis) with higher systolic blood pressure (P < 0...

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...

Purpose: To describe a patient with acute central retinal artery occlusion (CRAO) during vitrectomy surgery and the possible role of vitrectomy in acute CRAO management. Observations: 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...

PURPOSE: To describe the relationship between the vitreous and the neovascularization of the disc (NVD) using swept source optical coherence tomography (SS-OCT) and OCT angiography (OCTA). STUDY DESIGN: Retrospective. METHODS: We examined 17 eyes of 11 consecutive patients diagnosed as NVD associated with proliferative diabetic retinopathy (PDR). The location of the NVD feeder or collector vessels were examined by using RTVue XR Avanti. To determine the condition of the posterior vitreous detachment (PVD) and the proliferative tissue of the NVD, we performed 12 mm horizontal and vertical scans through the disc using SS-OCT...

PURPOSE: Our aim is to present in this online supplementa ry video (see an easy new surgical technique using blue dye to dissect the posterior hyaloid when performing pars plana vitrectomy. PROCEDURES: Dual-Blue stain is injected in vitreous cavity just after central vitrectomy is performed. The distribution of the blue stain will allow us to know if there is a posterior vitreous detachment or not ("blue lake fashion" or "blue jelly fashion," respectively) and as an excellent visualization of the vitreous fibers is accomplished, dissection of the posterior hyaloid can be performed without difficulty...

Retinal detachment is an ophthalmologic emergency that requires immediate medical attention as it can potentially lead to permanent vision loss. The gold standard for diagnosing retinal detachment is dilated funduscopic exam. However, when this exam is not feasible such as in an emergency room setting or if visualization of the posterior portion of the eye is not possible due to vitreous hemorrhage or dense cataracts, ocular ultrasound provides a readily available and effective alternative. We present the sonographic appearance of chronic retinal detachment in a 24-year-old female with a longstanding history of poorly controlled type 1 diabetes who could not undergo dilated funduscopic exam due to intra-ocular hemorrhage...

BACKGROUND: Cataract formation or acceleration can occur after intraocular surgery, especially following vitrectomy, a surgical technique for removing the vitreous that is used in the treatment of many disorders that affect the posterior segment of the eye. The underlying problem that led to vitrectomy may limit the benefit from removal of the cataractous lens. OBJECTIVES: To evaluate the effectiveness and safety of surgery versus no surgery for postvitrectomy cataract with respect to visual acuity, quality of life, and other outcomes...

The incidence of rhegmatogenous retinal detachment in the European population is approximately 10 cases per 100,000 inhabitants per year and reaches a peak in the 6th and 7th decades of life, mostly in atemporal association with posterior vitreous body detachment. Known risk factors include myopia and higher axial length of the eye, male gender, previous trauma and vitreoretinal degeneration or dystrophy. In recent years, an increase in the risk of rhegmatogenous retinal detachment following cataract surgery was also found, especially after capsule rupture and vitreous body loss...

OBJECTIVES: We describe a case of acute bilateral posterior vitreous detachment (PVD) in a 71-year-old female, which developed during a course of electroconvulsive therapy (ECT) for treatment-resistant depression. The risks and benefits of continuing ECT were assessed and the patient completed the full course of 16 ECT treatments without further ophthalmic complications. CONCLUSIONS: As the incidence of PVD increases with age, and ECT is used more frequently in elderly people with depression, we recommend paying attention to ophthalmic symptoms as part of the routine clinical monitoring of ECT side effects...

INTRODUCTION: In the absence of sufficient capsular support, scleral fixation of the intraocular lens is an interesting alternative. The goal is to evaluate this implantation technique when traditional implantation is impossible. PATIENTS AND METHODS: This is an observational, retrospective, monocentric study at the Amiens university medical center between August 2013 and March 2016. Patients all underwent scleral fixation of a three-piece implant without suturing of the haptics, after posterior vitrectomy...

BACKGROUND: Osteogenesis imperfecta (OI) is a rare primarily autosomal dominant condition in which the connective tissues of bones, ligaments and sclerae do not form properly. Typically, mutations in COL1A1 and COL1A2 genes lead to the defective formation or quantity of type I collagen, the principle matrix in these tissues. Molecular genetic studies have now elucidated multiple genetic subtypes of the disorder but little literature exists on the risk of retinal tears and detachments in OI...

Dome-shaped macula (DSM) is an entity recently described as a convex anterior protrusion of the macular area within a posterior myopic staphyloma. Specific complications were associated with DSM, like serous retinal detachment (SRD). We describe a woman presenting with a decreased vision at 20/50. SD-OCT scans were performed, showing a macular bulge. SRD was present and an epiretinal membrane could also be observed. Fluorescein angiography and indocyanin green angiography did not show any leakage nor choroidal neovascularization...
