E-mail: [email protected] KKEYEY WWORDS:ORDS: Adverse drug reaction, central serous retinopathy, corticosteroids Introduction Figure 1: Hyperfl uorescence at site of the leakage Central serous chorioretinopathy (CSR) is a well-established clinical entity known to occur in individuals with type A personality. Its incidence is 9.9 per 100000 for men and 1.7 for women.[1] Systemic corticosteroid therapy triggers this condition.[2] The prevalence of steroid-induced CSR is less than 10%.[3] We report here a case of CSR due to oral prednisolone therapy. Case Report A 24- year -old man with left sided facial palsy was prescribed tablet prednisolone 60 mg per day for five days. Three days after initiation of prednisolone, the patient reported seeing black spots in his vision in the right eye. Primary investigations (perimetry and fundus examination) revealed central scotoma in the right eye. Fluorescein angiography showed an early spot of hyperfluorescence at the site of leakage with expansion into the area of serous detachment [Figure 1]. Based on these observations, the patient was diagnosed as a Discussion case of central serous retinopathy. The dose of prednisolone was gradually reduced after the appearance of ADR. It was reduced There are various causes of CSR, including stress, type A to 40 mg for seven days and then it was stopped. Ketorolac eye personality and treatment with corticosteroids.

The time course of the onset of ADR and response to dechallenge suggests the probability of prednisolone as the causal drug.

The vast majority of these are preventable.2 Open globe injuries are injuries where the cornea and/or sclera are breached and there is a full-thickness wound of the eye wall.3 It can be further delineated into globe rupture from blunt trauma and lacerations from sharp objects. When a large blunt object impacts onto the eye, there is an instant increase in intraocular pressure and the eye wall yields at its weakest point leading to tissue prolapse.4 Open globe lacerations are caused by sharp objects or projectiles and subdivided into either penetrating or perforating injuries.

The cornea makes up the anterior por- tion of the globe and provides multiple functions for vision: it is transparent (despite originating from surface ectoderm), thereby allowing for clear vision; it acts as the major refractive (bending of light) surface of the globe; and it provides a protective barrier between the globe and the environment The cornea consists of 4 layers in domestic species, being approximately 0.45–0.55 mm thick in the normal dog.

Emergency Medicine, Polk County Fire Rescue, Bartow, USA Corresponding author: Rohan Mangal, [email protected] Abstract The authors present a case of globe rupture from a fall in an elderly patient. This patient had her intraocular contents protruding and experienced complete vision loss in her right eye. The emergency management and downstream surgical care is discussed, as well as the use of the Ocular Trauma Score to predict prognosis. Our patient had an Ocular Trauma Score of 1, considering right retinal detachment and perforating injury. Categories: Emergency Medicine, Ophthalmology Keywords: emergency medicine, ophthalmology, trauma, globe rupture Introduction Amongst serious eye injuries, 40% are attributable to penetrating and perforating injury [1]. Globe rupture occurs when the structure of the cornea or sclera is disrupted, usually due to trauma. Symptoms of globe rupture include eye deformity, eye pain, and vision loss. Sometimes, if blunt force directly impacts the eye, the sclera may rupture due to intraocular pressure. Globe injuries are relatively uncommon, with an incidence of 3.5 per 100,000 eye injuries [2].

  • Ocular Emergencies Brady Beale, VMD, DACVO (Ophthalmology) University of Pennsylvania School of Veterinary Medicine
    Ocular Emergencies Brady Beale, VMD, DACVO (Ophthalmology) University of Pennsylvania School of Veterinary Medicine From acute loss of vision to sudden pain, redness, and clouding of the eye, patients present to the emergency room for a variety of underlying causes. Uncovering the diagnosis can be difficult, but a thorough history coupled with basic ophthalmic tests and equipment can facilitate reaching an accurate conclusion. Obtaining a relevant ocular history uncovers how rapidly the clinical signs appeared, whether vision differs depending on lighting conditions, and whether an owner is currently administering any medications that might alter the diagnostic test results. When possible, the exam should begin with eliciting a menace response, pupillary light reflexes (PLR), dazzle reflexes, and palpebral reflex followed by a Schirmer tear test, fluorescein stain and tonometry. Evaluation of the eye should include the lids, conjunctiva, cornea, anterior chamber and lens, using diffuse light or a slit lamp. In small animals, the fundic exam is preferably performed with an indirect light source and hand held lens. While the sudden red, cloudy, squinting eye could represent glaucoma, corneal ulcer, lens luxation or sudden keratoconjunctivitis sicca, performing the eye exam in a routine, systematic fashion will help reveal the underlying cause. GLAUCOMA Glaucoma describes an increase in intraocular pressure that leads to vision loss. The elevated pressure disturbs the axoplasmic flow in the optic nerve and damages the inner retinal layers (retinal ganglion cells and nerve fiber layers) as well as the outer retinal layers (outer nuclear layers and the rods and cones). This damage leads to loss of vision and pain with sustained high intraocular pressures.
