A Case of Serious Eye Injury Caused by a Mistaken Injection of Methylrosaniline Chloride During Vitreous Surgery
Previous studies have reported that although methylrosaniline chloride (MRC), also known as “gentian violet,” was once used to treat Candida and as a skin disinfectant, its use in the clinical setting has diminished due to the development of antibiotic drugs.1,2 In recent years, MRC has reportedly been used for marking skin during surgery and for staining lesions in endoscopy;3,4 howev er, it is rarely used for intraocular surgery. Here we report the case of a patient in whom serious eye disorders immediately developed following highly concentrated MRC being mistakenly injected into the (Source: Ophthalmic Surgery, Las...

Full-Term Neonatal Ophthalmic Screening in China: A Review of 4-Year Outcomes
Preschool children with vision problems rarely actively complain about their visual impairment, which, if not treated, may become progressively worse. Therefore, effective eye screening programs and examinations to identify ocular disorders in young children are important. Eye examinations and testing for visual acuity (VA) in children are not usually performed until around 3 years of age in China. The majority of ocular health issues can be revealed by screening and subjective VA tests as soon as the children are old enough to cooperate with such tests. However, some ocular disorders may (Source: Ophthalmic Surgery, Laser...

Chorioretinal Perfusion in Persistent Placoid Maculopathy
Persistent placoid maculopathy (PPM) is a rare clinical entity, first reported by Golchet et al. in 2007.1 PPM was described with the presence of well-defined, plaque-like lesions involving the macula that spared the peripapillary zone with a characteristic appearance on fluorescein angiography (FA) and indocyanine green angiography (ICGA).Although PPM has been described with clinical features resembling those of other maculopathies, including serpiginous choroiditis, relentless placoid chorioretinitis, and acute posterior multifocal placoid pigment epitheliopathy,2 –4 the etiology of this (Source: Ophthalmic Surgery, La...

Failed Pneumatic Retinopexy for Rhegmatogenous Retinal Detachment Repair in Ocular Albinism: Clues to the Role of Melanin in Retinal Pigment Epithelium Pump Function
We report a case of failed PR for RRD repair in a patient with OA that highlights some of the basic concepts of RPE pump illustrated in other studies of OA.A 54-year-old white (Source: Ophthalmic Surgery, Lasers and Imaging : the Official Journal of the International Society for Imaging in the Eye)

Optical Coherence Tomography in Patients With the Subretinal Implant Retina Implant Alpha IMS
Retinal implants attempt to partially restore very low vision in legally blind patients with end-stage hereditary retinal dystrophies whose visual function is reduced to perception of light or less.1In advanced stages of hereditary retinal dystrophies, such as retinitis pigmentosa, a profound loss of photoreceptors occurs.2 The neural mechanisms proximal to the photoreceptors, specifically the bipolar cells and ganglion cells, however, may be sufficiently preserved to convey information to the brain. This condition is utilized in retinal prosthetic devices attempting to partially restore (Source: Ophthalmic Surgery, Lasers...

Choroidal Thickness Change in Patients With Diabetic Macular Edema
Diabetic macular edema (DME) is a leading cause of visual impairment in individuals of working age.1 The pathogenesis of DME has long been attributed to retinal vascular hyperpermeability that is seen on fluorescein angiography. Clinical and experimental findings suggested that choroidal vasculopathy in diabetes may play a role in the pathogenesis of diabetic retinopathy.2,3Various choroidal abnormalities, including loss of the choriocapillaris, increased tortuosity, narrowing and dilation of vessels, and sinus-like structure formation between choroidal lobules, have been reported in previous (Source: Ophthalmic Surgery, L...

Whether to Ignore the Macular Hole in a Uveitic Patient: A Discussion of the Pros and Cons of Elective Macular Surgery in a Challenging Population
Howard F. Fine, Practical Retina Co-EditorOften, surgery in a patient with uveitis is deferred as long as possible to avoid inflammatory complications. The difficulty typically lies not in the technical aspects of the procedure, but often in the perioperative management to avoid recurrences of and complications from uveitis.However, modern vitreoretinal surgery has evolved to employ minimally invasive approaches that incur only minimal postoperative inflammation in routine cases. Because of these advances, the risk-benefit ratio has changed over time for these complex cases.The literature on (Source: Ophthalmic Surgery, La...

Non-Mydriatic Ultra-Widefield Imaging Compared With Single-Field Imaging in the Evaluation of Peripheral Retinal Pathology
Retinal imaging is an important adjunct to the diagnosis, management, and monitoring of various posterior segment conditions. Traditionally, single-field fundus photography is used to evaluate and monitor diseases primarily involving the posterior pole, such as macular degeneration, glaucoma, and optic neuropathy, among others. It effectively captures the posterior pole, including the macula and optic nerve, covering a 20 ° to 50° field of view. It is also routinely used for the diagnosis, treatment, and monitoring of posterior segment conditions that may extend beyond the posterior pole, such (Source: Ophthalmic Surgery...

Characteristics of the Choriocapillaris Layer in Optical Coherence Tomography Angiography of Acute Central Serous Chorioretinopathy
Central serous chorioretinopathy (CSC) is a chorioretinal disease. Diffuse or focal dysfunction of the retinal pigment epithelium (RPE) is led by increased permeability from the choriocapillaris, which in turn causes a detachment of the neurosensory retina.1 –6 Albrecht first discovered this disease in 1866, known as central recurrent retinitis. Subsequently, the name underwent a series of changes, before finally being denoted as “central serous chorioretinopathy” by Gass et al. in 1967.1Nowadays, a large number of people, especially the middle-aged, suffer from this vision threat. Since the (Source: Ophthalmic Surge...

Outer Retinal Changes on Spectral-Domain Optical Coherence Tomography Pre- and Post-Silicone Oil Removal
Vision loss associated with intraocular silicone oil (SiO) tamponade may be the result of various factors, such as optic neuropathy and retinal toxicity, although the exact pathophysiology remains unclear.1 –5 Histopathologic studies have correlated the presence of SiO droplets within ocular tissues, including the iris, retina, trabecular meshwork, ciliary body, and epiretinal membranes (ERMs), with associated localized inflammation.6,7 Additionally, anterior segment pathology such as glaucoma, catar act, and keratopathy are known complications of prolonged SiO tamponade.8–10The risk for (Source: Ophthalmic Surgery, La...

A Frag Bag for Efficient Removal of Dislocated Nuclear Material
Posterior dislocation of the entire crystalline lens or nuclear fragments into the vitreous cavity may occur as a complication of cataract surgery, closed globe injury, connective tissue disorders, or other systemic conditions. Pars plana vitrectomy with phacofragmentation is a commonly utilized technique for removal of lens material from the vitreous cavity.1 However, the enlargement of one or more sclerotomies to accommodate the 20-gauge phacofragmatome in the era of smaller-gauge vitreous surgery may increase the risk of postoperative hypotony, vitreous incarceration, retinal detachment, (Source: Ophthalmic Surgery, Las...

Positive Visual Phenomena Following Implantation of the Argus II Retinal Prosthesis
The Argus II Retinal Prosthesis System (Second Sight Medical Products, Sylmar, CA) is the only U.S. Food and Drug Administration-approved implantable to date to restore vision in blind patients with retinitis pigmentosa (RP).1,2 The device consists of a spectacle-mounted camera that records the environment images and transfers light stimuli to a video processing unit that converts the light to pulsatile electronic signals forming a brightness map. The electronic signals are transferred to an array of 60 electrodes fixated to the surface of the retina in the macula. The surviving inner retinal (Source: Ophthalmic Surgery, L...
