  • 12 Retina Gabriele K
    299 12 Retina Gabriele K. Lang and Gerhard K. Lang 12.1 Basic Knowledge The retina is the innermost of three successive layers of the globe. It comprises two parts: ❖ A photoreceptive part (pars optica retinae), comprising the first nine of the 10 layers listed below. ❖ A nonreceptive part (pars caeca retinae) forming the epithelium of the cil- iary body and iris. The pars optica retinae merges with the pars ceca retinae at the ora serrata. Embryology: The retina develops from a diverticulum of the forebrain (proen- cephalon). Optic vesicles develop which then invaginate to form a double- walled bowl, the optic cup. The outer wall becomes the pigment epithelium, and the inner wall later differentiates into the nine layers of the retina. The retina remains linked to the forebrain throughout life through a structure known as the retinohypothalamic tract. Thickness of the retina (Fig. 12.1) Layers of the retina: Moving inward along the path of incident light, the individual layers of the retina are as follows (Fig. 12.2): 1. Inner limiting membrane (glial cell fibers separating the retina from the vitreous body). 2. Layer of optic nerve fibers (axons of the third neuron). 3. Layer of ganglion cells (cell nuclei of the multipolar ganglion cells of the third neuron; “data acquisition system”). 4. Inner plexiform layer (synapses between the axons of the second neuron and dendrites of the third neuron). 5. Inner nuclear layer (cell nuclei of the bipolar nerve cells of the second neuron, horizontal cells, and amacrine cells). 6. Outer plexiform layer (synapses between the axons of the first neuron and dendrites of the second neuron).

Lima10, Marta Figueroa11, Michel Farah10 and Giovanna Chico1 Abstract Purpose: To report the incidence and clinical features of patients that experienced un-explained visual loss following silicone oil (SO) removal. Methods: Multicenter retrospective study of patients that underwent SO removal during 2000–2012. Visual loss of 2 lines was considered signifcant. ≥ Results: A total of 324 eyes of 324 patients underwent SO removal during the study period. Forty two (13%) eyes sufered a signifcant visual loss following SO removal. Twenty three (7.1%) of these eyes lost vision secondary to known causes. In the remaining 19 (5.9%) eyes, the loss of vision was not explained by any other pathology. Eleven of these 19 patients (57.9%) were male. The mean age of this group was 49.2 16.4 years. Eyes that had an un-explained visual loss had a mean IOP while the eye was flled with SO of 19.6 6.9 mm± Hg. The length of time that the eye was flled with SO was 14.8 4.4 months. In comparison, eyes that± did not experience visual loss had a mean IOP of 14 7.3 mm Hg (p < 0.0002)± and a mean tamponade duration of 9.3 10.9 months (p < 0.0001).

  • Endogenous Brucella Endophthalmitis: a Case Report
    Saudi Journal of Ophthalmology (2017) xxx, xxx–xxx Case Report Endogenous Brucella endophthalmitis: A case report ⇑ Merih Oray a, ; Zafer Cebeci a; Nur Kir a; Banu Turgut Ozturk b; Lutfiye Oksuz c; Ilknur Tugal-Tutkun a Abstract Brucellosis may be associated with a wide range of ophthalmic manifestations including endophthalmitis, which is a sight- threatening condition that needs to be rapidly recognized and treated to avoid permanent visual loss. A 26-year-old female with a 6-month history of vision loss in the left eye was treated with high dose systemic corticosteroids and azathioprine with an initial misdiagnosis elsewhere. A dense vitreous haze with opacities at the posterior hyaloid and a wide area of retinochoroiditis led to the diagnosis of endogenous endophthalmitis at presentation to us. The vitreous sample and blood cultures demonstrated growth of Brucella melitensis. She received 6 months of systemic antibiotherapy, which resulted in resolution of inflammation; however, visual acuity remained poor due to irreversible damage. Infectious etiology, including brucellosis in endemic countries, has to be considered in the differential diagnosis before administering immunomodulatory therapy in patients with panuveitis of unknown origin.

  • Morphological Aspect of Tapetum Lucidum at Some Domestic Animals
    Bulletin UASVM, Veterinary Medicine 65(2)/2008 pISSN 1843-5270; eISSN 1843-5378 MORPHOLOGICAL ASPECT OF TAPETUM LUCIDUM AT SOME DOMESTIC ANIMALS Donis ă Alina, A. Muste, F.Beteg, Roxana Briciu University of Angronomical Sciences and Veterinary Medicine Calea M ănăş tur 3-5 Cluj-Napoca [email protected] Keywords: animal ophthalmology, eye fundus, tapetum lucidum. Abstract: The ocular microanatomy of a nocturnal and a diurnal eye are very different, with compromises needed in the arrhythmic eye. Anatomic differences in light gathering are found in the organization of the retina and the optical system. The presence of a tapetum lucidum influences the light. The tapetum lucidum represents a remarkable example of neural cell and tissue specialization as an adaptation to a dim light environment and, despite these differences, all tapetal variants act to increase retinal sensitivity by reflecting light back through the photoreceptor layer. This study propose an eye fundus examination, in animals of different species: cattles, sheep, pigs, dogs cats and rabbits, to determine the presence or absence of tapetum lucidum, and his characteristics by species to species, age and even breed. Our observation were made between 2005 - 2007 at the surgery pathology clinic from FMV Cluj, on 31 subjects from different species like horses, dogs and cats (25 animals). MATERIAL AND METHOD Our observation were made between 2005 - 2007 at the surgery pathology clinic from FMV Cluj, on 30 subjects from different species like cattles, sheep, pigs, dogs cats and rabbits.The animals were halt and the examination was made with minimal tranquilization.

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.

  • Cranial Nerve Palsy
    Cranial Nerve Palsy What is a cranial nerve? Cranial nerves are nerves that lead directly from the brain to parts of our head, face, and trunk. There are 12 pairs of cranial nerves and some are involved in special senses (sight, smell, hearing, taste, feeling) while others control muscles and glands. Which cranial nerves pertain to the eyes? The second cranial nerve is called the optic nerve. It sends visual information from the eye to the brain. The third cranial nerve is called the oculomotor nerve. It is involved with eye movement, eyelid movement, and the function of the pupil and lens inside the eye. The fourth cranial nerve is called the trochlear nerve and the sixth cranial nerve is called the abducens nerve. They each innervate an eye muscle involved in eye movement. The fifth cranial nerve is called the trigeminal nerve. It provides facial touch sensation (including sensation on the eye). What is a cranial nerve palsy? A palsy is a lack of function of a nerve. A cranial nerve palsy may cause a complete or partial weakness or paralysis of the areas served by the affected nerve. In the case of a cranial nerve that has multiple functions (such as the oculomotor nerve), it is possible for a palsy to affect all of the various functions or only some of the functions of that nerve. What are some causes of a cranial nerve palsy? A cranial nerve palsy can occur due to a variety of causes. It can be congenital (present at birth), traumatic, or due to blood vessel disease (hypertension, diabetes, strokes, aneurysms, etc).
