Multipurpose Conical Orbital Implant in Evisceration
Ophthalmic Plastic and Reconstructive Surgery Vol. 21, No. 5, pp 376–378 ©2005 The American Society of Ophthalmic Plastic and Reconstructive Surgery, Inc. Multipurpose Conical Orbital Implant in Evisceration Harry Marshak, M.D., and Steven C. Dresner, M.D. Doheny Eye Institute, Keck School of Medicine, University of Southern California, Los Angeles, California, U.S.A. Purpose: To evaluate the safety and efficacy of the porous polyethylene multipurpose conical orbital implant for use in evisceration. Methods: A retrospective review of 31 eyes that underwent evisceration and received the multipurpose conical orbital implant. The orbits were evaluated at 1 week, 1 month, and 6 months after final prosthetic fitting for implant exposure, superior sulcus deformity, and prosthetic motility. Results: There were no cases of extrusion, migration, or infection. All patients had a good cosmetic result after final prosthetic fitting. Prosthetic motility was good in all patients. Exposure developed in one eye (3%) and a superior sulcus deformity developed in one eye (3%). Conclusions: Placement of an multipurpose conical orbital implant in conjunction with evisceration is a safe and effective treatment for blind painful eye that achieves good motility and a good cosmetic result. visceration has proved to be effective for the treat- forms anteriorly to the sclera to be closed over it, without Ement of blind painful eye from phthisis bulbi or crowding the fornices, and extends posteriorly through endophthalmitis.

Corneal Abrasion
Corneal Abrasion What is a corneal abrasion? A corneal abrasion is a scratch on the surface of the clear part of the eye (cornea). It is most commonly due to trauma/injury. What are the symptoms of a corneal abrasion? Pain which can be severe Foreign body sensation Blurred vision Sensitivity to light Tearing (watering eyes) Redness What is the treatment of a corneal abrasion? Eye medication: Antibiotic drops or ointment used 3-4 times a day to prevent infection Dilating drops to decrease pain if you have a large corneal abrasion (this relieves spasm of the internal eye muscles. Please note that it will blur vision-particularly with reading.This effect may last for a few days after drop has been ceased.) Additional pain relief: Oral paracetamol, paracetamol and codeine Ice packs (place over injured eye: eyelids closed, ice pack covered in soft cloth) Sunglasses out of doors While an anaesthetic eye drop relieves immediate pain and allows the doctor to examine your eye, these drops cannot be used at home since they interfere with the natural healing of the cornea. What are the possible complications of a corneal abrasion? Infection Blurred vision from scarring Recurrent erosion syndrome: recurrent irritation from a poorly healed abrasion is most common after trauma from a sharp object such as a fingernail or paper. Corneal Abrasion Page 1 of 2 Things to remember: Most corneal abrasions heal within 3-4 days with pain improving each day until it has healed completely Do not rub your eye after the injury Do not touch your eye with cotton buds or tweezers Do not wear contact lenses until the eye has healed fully Seek medical attention if there is persistent or worsening discomfort, redness or decreased vision. -

Protocols for Injuries to the Eye Corneal Abrasion I
PROTOCOLS FOR INJURIES TO THE EYE CORNEAL ABRASION I. BACKGROUND A corneal abrasion is usually caused by a foreign body or other object striking the eye. This results in a disruption of the corneal epithelium. II. DIAGNOSTIC CRITERIA A. Pertinent History and Physical Findings Patients complain of pain and blurred vision. Photophobia may also be present. Symptoms may not occur for several hours following an injury. B. Appropriate Diagnostic Tests and Examinations Comprehensive examination by an ophthalmologist to rule out a foreign body under the lids, embedded in the cornea or sclera, or penetrating into the eye. The comprehensive examination should include a determination of visual acuity, a slit lamp examination and a dilated fundus examination when indicated. III. TREATMENT A. Outpatient Treatment Topical antibiotics, cycloplegics, and pressure patch at the discretion of the physician. Analgesics may be indicated for severe pain. B. Duration of Treatment May require daily visits until cornea sufficiently healed, usually within twenty-four to seventy-two hours but may be longer with more extensive injuries. In uncomplicated cases, return to work anticipated within one to two days. The duration of disability may be longer if significant iritis is present. IV. ANTICIPATED OUTCOME Full recovery. CORNEAL FOREIGN BODY I. BACKGROUND A corneal foreign body most often occurs when striking metal on metal or striking stone. Auto body workers and machinists are the greatest risk for a corneal foreign body. Hot metal may perforate the cornea and enter the eye. Foreign bodies may be contaminated and pose a risk for corneal ulcers. II. DIAGNOSTIC CRITERIA A. Pertinent History and Physical Findings The onset of pain occurs either immediately after the injury or within the first twenty-four hours. -

Treatment of Congenital Ptosis
13 Review Article Page 1 of 13 Treatment of congenital ptosis Vladimir Kratky1,2^ 1Department of Ophthalmology, Queen’s University, Kingston, Canada; 21st Medical Faculty, Charles University, Prague, Czech Republic Correspondence to: Vladimir Kratky, BSc, MD, FRCSC, DABO. Associate Professor of Ophthalmology, Director of Ophthalmic Plastic and Orbital Surgery, Oculoplastics Fellowship Director, Queen’s University, Kingston, Canada; 1st Medical Faculty, Charles University, Prague, Czech Republic. Email: [email protected]. Abstract: Congenital ptosis is an abnormally low position of the upper eyelid, with respect to the visual axis in the primary gaze. It can be present at birth or manifest itself during the first year of life and can be bilateral or unilateral. Additionally, it may be an isolated finding or part of a constellation of signs of a specific syndrome or systemic associations. Depending on how much it interferes with the visual axis, it may be considered as a functional or a cosmetic condition. In childhood, functional ptosis can lead to deprivation amblyopia and astigmatism and needs to be treated. However, even mild ptosis with normal vision can lead to psychosocial problems and correction is also advised, albeit on a less urgent basis. Although, patching and glasses can be prescribed to treat the amblyopia, the mainstay of management is surgical. There are several types of surgical procedure available depending on the severity and etiology of the droopy eyelid. The first part of this paper will review the different categories of congenital ptosis, including more common associated syndromes. The latter part will briefly cover the different surgical approaches, with emphasis on how to choose the correct condition. -
The Simplified Trachoma Grading System, Amended Anthony W Solomon,A Amir B Kello,B Mathieu Bangert,A Sheila K West,C Hugh R Taylor,D Rabebe Tekeraoie & Allen Fosterf
PolicyPolicy & practice & practice The simplified trachoma grading system, amended Anthony W Solomon,a Amir B Kello,b Mathieu Bangert,a Sheila K West,c Hugh R Taylor,d Rabebe Tekeraoie & Allen Fosterf Abstract A simplified grading system for trachoma was published by the World Health Organization (WHO) in 1987. Intended for use by non-specialist personnel working at community level, the system includes five signs, each of which can be present or absent in any eye: (i) trachomatous trichiasis; (ii) corneal opacity; (iii) trachomatous inflammation—follicular; (iv) trachomatous inflammation—intense; and (v) trachomatous scarring. Though neither perfectly sensitive nor perfectly specific for trachoma, these signs have been essential tools for identifying populations that need interventions to eliminate trachoma as a public health problem. In 2018, at WHO’s 4th global scientific meeting on trachoma, the definition of one of the signs, trachomatous trichiasis, was amended to exclude trichiasis that affects only the lower eyelid. This paper presents the amended system, updates its presentation, offers notes on its use and identifies areas of ongoing debate.

Corneal Ulcers in Cats
Corneal Ulcers in Cats 803-808-7387 www.gracepets.com The cornea is the clear, shiny membrane that makes up the surface of the eyeball. It is much like a clear window. To understand a corneal ulcer, you must first understand how the cornea is constructed. The cornea is comprised of three layers. The most superficial or outermost layer is the epithelium. This layer is comprised of many, very thin layers of cells, similar to an onion’s skin. Below the epithelium is the stroma and the deepest layer is Descemet's membrane. Because all of these layers are clear, it is not possible to see them without special stains and a microscope. Erosion through a few layers of the epithelium is called a corneal erosion or corneal abrasion. A corneal ulcer is an erosion through the entire epithelium and down into the stroma. If the erosion goes through the epithelium and stroma to the level of Descemet's membrane, a descemetocele exists. If Descemet's membrane ruptures, the liquid inside the eyeball leaks out and the eye collapses. What causes corneal ulcers? There are several causes for corneal ulcers in cats. The most common is trauma. An ulcer may result from blunt trauma, such as a cat rubbing its eye on a carpet, or due to a laceration, such as a cat-claw scratch. The second most common cause is chemical burn of the cornea. This may happen when irritating shampoo or dip gets in the eye. Less common causes of corneal ulcers include bacterial infections, viral infections, and other diseases.
