Significant Reduction of Radiation Exposure Using Specific Settings of the O-Arm for Percutaneous Cementoplasty in Accordance With the ALARA Principle.

Background: Three-dimensional (3D) navigation has become routinely used in spine surgery, allowing more accurate and safe procedures. However, radiation exposure related to the use of imaging is an unresolved issue, and information about it is relatively scarce. The "as low as reasonably achievable" (ALARA) principle aims to reduce the radiation exposure for the patients as low as possible.

Simultaneous Management of Retinal Detachment and Aphakia with Pars Plana Vitrectomy, Silicone Oil Tamponade and Retropupillary Iris-Claw Intraocular Lens Implantation in These Cases.

Background: Marfan Syndrome is an autosomal dominant disease with multiple ocular abnormalities including ectopia lentis and a high incidence of rhegmatogenous retinal detachment (RRD). The management of RRD may be challenging in cases of aphakic patients with Marfan.

Purpose: To report on the management of four cases of simultaneous RRD and aphakia with vitrectomy, silicone oil tamponade, and retropupillary iris-claw intraocular lens (IOL) implantation in patients with Marfan that have been operated at the Jules-Gonin Eye Hospital between 2019 and 2020.

Crystals deposits in the anterior and posterior lens cortex in Bietti corneo-retinal dystrophy.

Background: Whereas crystals deposit in the retina, the cornea and limbus in Bietty corneo-retinal dystrophy (BCD) is now well established and documented, only two published cases report their findings in the lens and no cases deep in the lens cortex.

Material And Methods: Four consecutive adult patients from three different unrelated families presenting lens crystals associated with advanced genetically confirmed BCD were enrolled with advanced disease and long follow up (>12 years). Demographics, visual acuity, slit lamp biomicroscopy, lens and posterior pole photography, optical coherence tomography (OCT), autofluorescence, and screening for CYP4V2 type of mutation were performed.

Awareness and practices regarding eye diseases among patients with diabetes: a cross sectional analysis of the CoDiab-VD cohort.

Background: The increasing prevalence of diabetes is leading to a rise of eye diseases, augmenting the risk of sight-threatening complications. The aim of this study was to evaluate prevalence, awareness and practices regarding eye diseases among patients with diabetes in the canton of Vaud, Switzerland.

Methods: A cohort of 323 patients with diabetes completed a self-administered questionnaire assessing prevalence, awareness and practices regarding eye diseases, besides health status and quality of care measures.

Intraocular Metastases--A Review.

Intraocular metastases almost invariably arise in the uveal tract, mostly in the posterior choroid. They are the most common type of intraocular malignancy and often the first sign of tumor dissemination. Choroidal metastases generally appear as a creamy white or pale yellow mass associated with subretinal fluid and may be multifocal and bilateral.

Incidence and Surgical Management of Simultaneous Bilateral Retinal Detachment.

Background: Simultaneous bilateral retinal detachment (RD) is very rare and its incidence has not been very well characterised.

Material And Methods: Retrospective review of RD cases treated at the Jules Gonin Eye Hospital between 1999 and 2010.

Results: Over the 11 year period, 10 patients (20 eyes) with simultaneous bilateral RD were identified (average incidence among RD= 0.

Intravitreal ranibizumab in the treatment of predominantly hemorrhagic lesions in exudative age-related macular degeneration.

Background: Submacular hemorrhage is a manifestation of neovascular age-related macular degeneration (AMD) that has a very poor natural history leading to severe visual loss. We have evaluated the safety and efficacy of intravitreal ranibizumab in the treatment of predominantly hemorrhagic AMD.

Patients And Methods: A retrospective study of patients with predominantly hemorrhagic AMD treated with intravitreal ranibizumab at the Jules Gonin Eye Hospital between December 2006 and December 2008 was undertaken.

Altered vision during motion: an unusual symptom of cerebellar dysfunction, quantifiable by a simple clinical test.

Purpose: To report a series of patients with cerebellar dysfunction and altered vision during motion, and to quantify their visual impairment in motion with a simple clinical test.

Methods: Twenty consecutive patients suffering from cerebellar dysfunction and altered vision during motion were examined between 1994 and 2007. A control group consisted of 20 age- and sex-matched healthy people.

Retinal pigment epithelium tears after intravitreal injection of ranibizumab for predominantly classic neovascular membranes secondary to age-related macular degeneration.

Purpose: Retinal pigment epithelium (RPE) tear is an extremely rare complication in patients with classic neovascular membranes without RPE detachment. We evaluate their incidence and functional outcome following treatment with intravitreal ranibizumab.

Methods: Observational study of 72 consecutive patients (74 eyes) treated at Jules Gonin University Eye Hospital, Lausanne, with intravitreal ranibizumab 0.

Ultrastructural changes of the internal limiting membrane removed during indocyanine green assisted peeling versus conventional surgery for idiopathic macular epiretinal membrane.

Purpose: To evaluate the histologic features of cellular retinal fragments on the internal limiting membrane (ILM) removed during idiopathic macular epiretinal membrane (MEM) peeling surgery with and without the aid of indocyanine green (ICG) diluted in 5% glucose.

Methods: ILM specimens removed from 88 eyes during idiopathic MEM surgery between 1995 and 2003 were reviewed retrospectively. Histologic analysis focused on the presence and characteristics of retinal fragments on the retinal surface of the ILM.

Differential diagnosis of leukocoria and strabismus, first presenting signs of retinoblastoma.

Leukocoria in infants is always a danger signal as retinoblastoma, a malignant retinal tumor, is responsible for half of the cases in this age group. More common signs should also be considered suspicious until proved otherwise, such as strabismus, the second most frequent sign of retinoblastoma. Less frequent manifestations are inflammatory conditions resistant to treatment, hypopyon, orbital cellulitis, hyphema or heterochromia.

Diagnosis and current management of retinoblastoma.

Retinoblastoma represents the prototypic model for inherited cancers. The RB1 gene was the first tumor suppressor gene to be identified. It represents the most frequent primary eye cancer in children under 15 years old, habitually occurring in infancy, even in utero, but can be observed in older children or young adults.

Blood-brain barrier disruption associated with topiramate-induced angle-closure glaucoma of acute onset.

Background: Topiramate (Topamax(R)) is an anti-epileptic drug of the sulfamate group used secondarily for bipolar disease.

History And Signs: One week after initiation of topiramate treatment for a bipolar disorder, a 57-year-old man presented with blurred vision. Clinical examination revealed a bilateral conjunctivitis, areflexic mydriasis, severe anterior chamber shallowing, with a myopic shift and vitritis.

Peripapillary choroidal neovascularization associated with melanocytoma of the optic disc: a clinicopathologic case report.

Background: Melanocytoma of the optic disc is a benign melanocytic tumor that rarely causes visual impairment. We report a case of a melanocytoma of the optic disc with a decreased vision related to a peripapillary choroidal neovascular membrane (PCNVM) that was successfully treated by submacular surgery.

Methods: A 45-year-old southern European patient had a melanocytoma of the optic disc in his left eye with vision of 20/100.

Purpose: To describe a previously unreported association between phakomatosis pigmentovascularis (PPV) IIa and primary choroidal melanoma.

Design: Case series.

Participants: Three patients with PPV type IIa and choroidal melanoma.
