BACKGROUND: Purtscher or Purtscher-like retinopathy is diagnosed by retinal hemorrhages and areas of retinal whitening on fundus examination, as well as a reduction in visual acuity due to microvascular occlusion of the precapillary retinal arterioles. We describe novel optical coherence tomography (OCT) findings of internal limiting membrane (ILM) separation and posterior hyperreflective dots in a case of Purtscher-like retinopathy in this report. METHODS: A 33-year-old man with acute pancreatitis and alcohol-induced liver disease presented to the retina department complaining of four days of painless vision loss in both eyes...

BACKGROUND: Laser skin resurfacing is a popular cosmetic procedure for noninvasive skin rejuvenation. Since health insurance plans often do not cover these types of procedures, patients often pay out of pocket. Consequently, there is an incentive to go abroad, where prices are more affordable. However, practitioners in destination countries may lack rigorous training on laser safety, regulatory oversight, or licensing, especially on devices used for "cosmetic" procedures. In certain cases, this can lead to tragic outcomes, especially when underqualified practitioners operate medical-grade laser devices...

PURPOSE: Choroideremia is an X-linked inherited retinal degeneration involving the choriocapillaris, retinal pigment epithelium, and photoreceptors. Adaptive optics scanning light ophthalmoscopy allows visualization of retinal structure at the level of individual cells and is well poised to provide insight into the pathophysiologic mechanisms underpinning the retinal degeneration in choroideremia. METHODS: Foveal adaptive optics scanning light ophthalmoscopy images of 102 eyes of 54 individuals with choroideremia were analyzed...

BACKGROUND AND OBJECTIVE: Epiretinal membrane (ERM) formation, a common complication following pars plana vitrectomy (PPV) for primary rhegmatogenous retinal detachment (RRD) repair, is associated with vision loss and metamorphopsias. Although laser retinopexy is generally associated with ERM formation, the correlation between the extent of laser treatment and ERM formation during PPV is not well established. The aim of this study was to identify risk factors associated with ERM formation including extend of endolaser retinopexy after PPV for primary RRD...

A 48-year-old male with oculocutaneous albinism (OCA) presented with bilateral diminution of vision. Ocular examination revealed bilateral central corneal thinning, scarring with ectasia, depigmented irides, transillumination defects, and pseudophakia. Examination of the right eye also revealed a hyperoleon, emulsified silicon oil in the vitreous cavity, and an attached retina, while the left eye had a total rhegmatogenous retinal detachment (RRD). This case describes a unique set of challenges (the presence of an ectatic scarred cornea and a hypopigmented fundus) and sodium fluorescein dye as an adjunct in the surgical management of a complex RRD...

A 54-year-old man presented to the ophthalmic emergency department of our center with eye pain and blurred vision in his right eye following a workplace accident. Examination revealed a penetrating corneal injury with the presence of an intraocular foreign body (IOFB) involving the corneoscleral limbus, perforating the cornea, iris, anterior lens capsule, and lens. Immediate surgical intervention was carried out with the extraction of the IOFB, identified as an 8 mm mussel shell fragment, and the removal of the resulting traumatic cataract...

PURPOSE: To demonstrate a novel surgical technique that is a low-cost alternative to commercial implants for macular buckling in high myopia. METHODS: A silicon encircling band serves as the anchor. A second silicon circling band is employed, with a 10mm silicon strip to widen the posterior scleral indentation. This band is inserted posteriorly the lateral and inferior rectus muscles and pushed behind the globe, orienting it in a superior-temporal to inferio-nasal position with the silicone strip directly under the macula...

PURPOSE: To report a technique consisting of inverted internal limiting membrane (ILM) flap coverage with autologous blood after air-fluid exchange and silicone oil tamponade in treating extensive retinal detachment (RD) secondary to a myopic macular hole (MH). METHODS: Retrospective case series. The technique was applied in 18 eyes with MH-RD extending beyond the equator with a minimum follow-up of 6 months. The procedures for pars plan vitrectomy (PPV) included the following:1) the ILM was peeled to the superior and inferior arcade margins, and except for the ILM in the temporal region, was hinged toward the edge of the MH...

Retinal necrosis is a severe condition that threatens visual function. It is caused by viruses that are known to cause acute retinal necrosis (ARN) and progressive outer retinal necrosis (PORN), which are called necrotizing herpetic retinopathies (NHR). ARN causes severe intraocular inflammation, including anterior chamber intravitreal cells, keratic precipitate, vitreous opacity, and retinal vasculitis, whereas intraocular inflammation in PORN is considered mild or virtually absent. In addition, PORN is a disease that manifests in immunosuppressive patients, such as those with acquired immunodeficiency syndrome...

INTRODUCTION: We present two cases of vitreous hemorrhage after micropulse cyclophotocoagulation one of which had concurrent hyphema. To the best of our knowledge, these are the first cases of vitreous hemorrhage due to micropulse CPC in the United States. CASE DESCRIPTION: The first case is an 82-year-old woman with bilateral severe primary open angle glaucoma. BCVA in the right eye was 20/25, and 10-2 Humphrey visual field showed severe peripheral defects. The patient underwent MPCPC of the right eye and at one week, a settled 2 mm hyphema and vitreous hemorrhage confirmed by B-scan were noted...

Retinal detachment (RD) occurs when the neurosensory retina, the neurovascular tissue responsible for phototransduction, is separated from the underlying retinal pigment epithelium (RPE). Given the importance of the RPE for optimal retinal function, RD invariably leads to decreased vision. There are three main types of RD: rhegmatogenous, tractional and exudative (also termed serous) RD. In rhegmatogenous RD, one or more retinal breaks enable vitreous fluid to enter the subretinal space and separate the neurosensory retina from the RPE...

Even though subconjunctival injections are used in clinics, their quantitative pharmacokinetics has not been studied systematically. For this purpose, we evaluated the ocular and plasma pharmacokinetics of subconjunctival dexamethasone in rabbits. Intravenous injection was also given to enable a better understanding of the systemic pharmacokinetics. Dexamethasone concentrations in plasma (after subconjunctival and intravenous injections) and four ocular tissues (iris-ciliary body, aqueous humour, neural retina and vitreous) were analysed using LC-MS/MS...
