Neovascular Glaucoma: Etiology, Diagnosis and Prognosis
Seminars in Ophthalmology, 24, 113–121, 2009 Copyright C Informa Healthcare USA, Inc. ISSN: 0882-0538 print / 1744-5205 online DOI: 10.1080/08820530902800801 Neovascular Glaucoma: Etiology, Diagnosis and Prognosis Tarek A. Shazly Mark A. Latina Department of Ophthalmology, Department of Ophthalmology, Massachusetts Eye and Ear Massachusetts Eye and Ear Infirmary, Boston, MA, USA, and Infirmary, Boston, MA, USA and Department of Ophthalmology, Department of Ophthalmology, Tufts Assiut University Hospital, Assiut, University School of Medicine, Egypt Boston, MA, USA ABSTRACT Neovascular glaucoma (NVG) is a severe form of glaucoma with devastating visual outcome at- tributed to new blood vessels obstructing aqueous humor outflow, usually secondary to widespread posterior segment ischemia. Invasion of the anterior chamber by a fibrovascular membrane ini- tially obstructs aqueous outflow in an open-angle fashion and later contracts to produce secondary synechial angle-closure glaucoma. The full blown picture of NVG is characteristized by iris neovas- cularization, a closed anterior chamber angle, and extremely high intraocular pressure (IOP) with severe ocular pain and usually poor vision.

MIOTICS in CATARACT SURGERY by Harold Beasley, MD
MIOTICS IN CATARACT SURGERY BY Harold Beasley, MD PROMPT MIOSIS OF the pupil after delivery of the lens in round pupil cataract surgery is recommended to protect the vitreous face, to prevent iris incarceration, and to facilitate the postplacement of corneoscleral sutures.1 It has been postulated that miosis also prevents the formation of peripheral anterior synechia, but this has not been demonstrated experimentally.2 An ideal miotic should produce prompt pupillary constriction and for a duration of 12 to 24 hours. It should also be nonirritating to anterior chamber structures. Acetylcholine ( 1.0 per cent)37 and a weak solution of carbachol (0.01 per cent) ,8 as well as pilocarpine, have been found to be satisfactory for this purpose. The purposes of this study were (1) to evaluate the effectiveness of miotics in preventing peripheral anterior synechia and in preserving the integrity of the vitreous face; and (2) to compare the effectiveness of acetylcholine 1 per cent and carbachol 0.01 per cent as miotics in round pupil cataract surgery. PROCEDURE This study compared three experimental treatments in a double blind procedure in which the code was left unbroken until all the data were accumulated. Selected patients were gonioscoped prior to surgery and only patients with grades Im or iv angles were chosen for this study. All patients were predosed with 2 per cent homatropine and 10 per cent phenylephrine. Prior to the injection of the test solution the pupillary diameters were measured before the section was made and immediately after lens extraction. Measurements were then made at two minutes and at five minutes after the intracameral instillation of 0.4- to 0.5-cc of the test solutions. -
Fibroblast Growth Factor-2 Drives and Maintains Progressive Corneal Neovascularization Following HSV-1 Infection
ARTICLES Fibroblast growth factor-2 drives and maintains progressive corneal neovascularization following HSV-1 infection HR Gurung1, MM Carr2, K Bryant2, AJ Chucair-Elliott2 and DJJ Carr1,2 Herpes simplex virus type 1 (HSV-1) infection of the cornea induces vascular endothelial growth factor A (VEGF-A)- dependent lymphangiogenesis that continues to develop well beyond the resolution of infection. Inflammatory leukocytes infiltrate the cornea and have been implicated to be essential for corneal neovascularization, an important clinically relevant manifestation of stromal keratitis. Here we report that cornea infiltrating leukocytes including neutrophils and T cells do not have a significant role in corneal neovascularization past virus clearance. Antibody- mediated depletion of these cells did not impact lymphatic or blood vessel genesis. Multiple pro-angiogenic factors including IL-6, angiopoietin-2, hepatocyte growth factor, fibroblast growth factor-2 (FGF-2), VEGF-A, and matrix metalloproteinase-9 were expressed within the cornea following virus clearance. A single bolus of dexamethasone at day 10 post infection (pi) resulted in suppression of blood vessel genesis and regression of lymphatic vessels at day 21 pi compared to control-treated mice. Whereas IL-6 neutralization had a modest impact on hemangiogenesis (days 14–21 pi) and lymphangiogenesis (day 21 pi) in a time-dependent fashion, neutralization of FGF-2 had a more pronounced effect on the suppression of neovascularization (blood and lymphatic vessels) in a time-dependent, leukocyte- independent manner. Furthermore, FGF-2 neutralization suppressed the expression of all pro-angiogenic factors measured and preserved visual acuity. INTRODUCTION corneal neovascularization is topical administration of steroid The cornea is an immune privileged tissue and its transparency is or non-steroid anti-inflammatory drugs, unwarranted side critical for optimal visual acuity. -
Ocular Complications of Endocarditis
7 Ocular Complications of Endocarditis Ozlem Sahin Middle East Technical University Health Sciences Department of Ophthalmology, Ankara Turkey 1. Introduction Cardiac complications are the most common complications in patients with infective endocarditis, and they can be related to significant mortality and morbidity. (1) Extra- cardiac manifestations along with their historical descriptions such as splinter hemorrhages, emboli, Osler’s nodes, Janeway and Bowman lesions of the eye, Roth’s spots, patechiae and clubbing generally result from thromboemboli or septic emboli. (2) Inflammatory complications may occur as a result of septic emboli, and these include endogenous (metastatic) endophthalmitis, focal abscess, and vasculitis. (3) In this chapter we mainly focus on the endogenous endophthalmitis arising as a complication of infective endocarditis. Endogenous (metastatic) endophthalmitis is an inflammatory condition of the intraocular structures including the aqueous, iris, lens, ciliary body, vitreous, choroid and retina. (4-6) It results from the hematogenous spread of organisms from a distant source of infection, most commonly infective endocarditis, gastrointestinal tract and urinary tract infections and wound infections. (7-9) Other sources of infection have included pharyngitis, pneumonia, septic arthritis and meningitis. (10,11) Compared with endophthalmitis following trauma or surgery, endogenous endophthalmitis is relatively rare, accounting 2-8% of all reported endophthalmitis cases. (5) However, endogenous endophthalmitis carries with it the danger of bilateral infection in 15-25% of cases. (6,12) 2. Epidemiology Endogenous endophthalmitis has been reported to occur at any age and no sexual predilection. (13) However, in the recent years the mean age of endogenous endophthalmitis has shifted to 65 years possibly because of the reduction in the incidence of rheumatic heart disease. -

Hyphema. Part I. Pathophysiologic Considerations Abstract Hemorrhage in the anterior chamber of the eye, or hyphema, results from a breakdown of the blood-ocular barrier (BOB) and is frequently associated with inflammation of the iris, ciliary body, or retina. Hyphema can also occur by retrograde blood flow into the anterior chamber via the aqueous humor drainage pathways without BOB breakdown. Hyphema attributable to blunt or perforating ocular trauma is more common than that resulting from endogenous causes. When trauma has been eliminated as a possible cause, it is prudent to assume that every animal with hyphema has a serious systemic disease until proven otherwise.

Clinical Practice Guidelines: Care of the Patient with Anterior Uveitis
OPTOMETRY: OPTOMETRIC CLINICAL THE PRIMARY EYE CARE PROFESSION PRACTICE GUIDELINE Doctors of optometry are independent primary health care providers who examine, diagnose, treat, and manage diseases and disorders of the visual system, the eye, and associated structures as well as diagnose related systemic conditions. Optometrists provide more than two-thirds of the primary eye care services in the United States. They are more widely distributed geographically than other eye care providers and are readily accessible for the delivery of eye and vision care services. There are approximately 32,000 full-time equivalent doctors of optometry currently in practice in the United States. Optometrists practice in more than 7,000 communities across the United States, serving as the sole primary eye care provider in more than 4,300 communities. Care of the Patient with The mission of the profession of optometry is to fulfill the vision and eye Anterior Uveitis care needs of the public through clinical care, research, and education, all of which enhance the quality of life.

Observation of Optic Disc Neovascularization Using OCT
www.nature.com/scientificreports OPEN Observation of optic disc neovascularization using OCT angiography in proliferative Received: 13 December 2017 Accepted: 16 February 2018 diabetic retinopathy after Published: xx xx xxxx intravitreal conbercept injections Xiao Zhang1, Chan Wu1, Li-jia Zhou2 & Rong-ping Dai1 This study reports the short-term efcacy and safety of intravitreal conbercept injections for neovascularization at the disc (NVD) in patients with proliferative diabetic retinopathy (PDR). Conbercept is a recombinant fusion protein with a high afnity for all isoforms of vascular endothelial growth factor (VEGF)-A, placental growth factor and VEGF-B. A prospective case series study was conducted in 15 patients (15 eyes). Patients had complete ocular examinations and received a 0.5 mg intravitreal conbercept injection followed by supplemental pan-retinal photocoagulation (PRP). Optical coherence tomography angiography (OCTA) was performed before and after treatment. Before treatment, the mean NVD area was 1.05 ± 0.33 mm2, and it decreased to 0.56 ± 0.17 mm2 after an interval of 7.5 d (p = 0.000). One eye required vitrectomy during follow-up. Recurrent NVD was observed in 2 eyes, which resolved after repeated injections. The remaining 12 eyes were stable over a mean follow-up period of 8.3 months. The mean area of the NVD in 14 patients without vitrectomy was 0.22 ± 0.11 mm2 (p = 0.000) at the last visit. Intravitreal conbercept injections combined with intensive PRP are an efective and safe treatment for PDR with NVD. Quantitative information on NVD can be obtained with OCTA, which may be clinically useful in evaluating the therapeutic efect. -
