Optic Disc Drusen in Differential Diagnosis of Optic Neuritis Optik Nörit Ayrıcı Tanısında Optik Disk Druzeni
DO I:10.4274/tnd.56514 Images in Clinical Neurology Optic Disc Drusen in Differential Diagnosis of Optic Neuritis Optik Nörit Ayrıcı Tanısında Optik Disk Druzeni Erkingül Shugaiv1, Elif Aksoy Güzeller2, Sait Alim2 1Tokat State Hospital, Clinic of Neurology, Tokat, Turkey 2Tokat State Hospital, Clinic of Diases Eye, Tokat, Turkey Optic disc drusen is a condition where a hyaline-like calcific object is accumulated on the optical nerve ending, often bilaterally (1). Its prevalence in the general population is 0.34-3.7%. It can be confused with optic papillitis since it blurs the papillary border at the bottom of the eye. Drusens can be seen as opacity in B-scan ultrasonography and computerized tomography (2). Optic disc drusens present with slowly progressing visual field defects. The 21-year-old patient who complained of blurry vision on both eyes did not have a history of disease. Her vision was blurry for the past 10 days, especially on the left side. There was no history of eyeball pain, headache, infection or trauma. Her vision was 0.2 on the right and 0.1 on the left side. The papillary borders were undefined on both sides in the examination of the base of Figure 1. Optic disc drusen on both sides: Discs are protruded due the eyes (Figure 1). Due to the slow clinical decline over 10 days, to the drusen and their borders are not clearly defined. cranial and spinal magnetic resonance imaging was conducted in order to address any possible demyelinating disease but did not produce any remarkable findings. After this, cranial and orbital tomography was conducted with the pre-diagnosis of optic disc drusen. -

Understanding Corneal Blindness
Understanding Corneal Blindness The cornea copes very well with minor injuries or abrasions. If the highly sensitive cornea is scratched, healthy cells slide over quickly and patch the injury before infection occurs and vision is affected. If the scratch penetrates the cornea more deeply, however, the healing process will take longer, at times resulting in greater pain, blurred vision, tearing, redness, and extreme sensitivity to light. These symptoms require professional treatment. Deeper scratches can also cause corneal scarring, resulting in a haze on the cornea that can greatly impair vision. In this case, a corneal transplant may be needed. Corneal Diseases and Disorders that May Require a Transplant Corneal Infections. Sometimes the cornea is damaged after a foreign object has penetrated the tissue, such as from a poke in the eye. At other times, bacteria or fungi from a contaminated contact lens can pass into the cornea. Situations like these can cause painful inflammation and corneal infections called keratitis. These infections can reduce visual clarity, produce corneal discharges, and perhaps erode the cornea. Corneal infections can also lead to corneal scarring, which can impair vision and may require a corneal transplant. Fuchs' Dystrophy. Fuchs' Dystrophy occurs when endothelial cells gradually deteriorate without any apparent reason. As more endothelial cells are lost over the years, the endothelium becomes less efficient at pumping water out of the stroma (the middle layers of the cornea). This causes the cornea to swell and distort vision. Eventually, the epithelium also takes on water, resulting in pain and severe visual impairment. Epithelial swelling damages vision by changing the cornea's normal curvature, and causing a sightimpairing haze to appear in the tissue. -

At its core, SOD is a disorder resulting from improper embryological development of mid-line brain structures. To date, there is no comprehensive understanding of the etiology of SOD. Currently, SOD is diagnosed based on the presence of at least two of the following three factors: (i) optic nerve hypoplasia (ii) improper pituitary gland development and endocrine dysfunction and (iii) mid-line brain defects, including agenesis of the septum pellucidum and/or corpus callosum. A literature review of existing research on the disorder was conducted. The medical history and genetic data of 6 patients diagnosed with SOD were reviewed to find damaging variants. -
