Pellucid definition5/25/2023 A significant number of patients were from higher socioeconomic status (93.74%) and from the urban region (45.08%). The majority (30.23%) of the patients were between 31 and 40 years of age. The mean age of the patients was 37.91 ± 13.19 years. The majority of patients were males (70.13%) with the bilateral affliction (77.1%). The prevalence rates were 0.004% in children (age <16 years) and 0.03% in adults. Overall, 559 (0.02%) new patients were diagnosed with PMD. The data were collected using an electronic medical record system. Patients with a clinical diagnosis of PMD in at least one eye were included as cases. This cross-sectional hospital-based study included 2,470,793 new patients presenting between September 2012 and September 2020 (~8 years period). Disease affecting the CSP can cause symptoms either by mass effect or by disturbance of the emotional and behavioral functions of the limbic system.The aim of this study was to describe the clinical profile and demographic distribution of pellucid marginal corneal degeneration (PMD) in patients presenting to a multitier ophthalmology hospital network in India. SP is an important part of the limbic system, with prominent connections to both the medial and the basolateral limbic circuit. Laterally - Leaflets of the septum pellucidum. Inferiorly - Anterior commissure and the rostrum of the corpus callosum and Posteriorly - Anterior limb and pillars of the fornix Medially - Virtual space with the contralateral septum Laterally - Medial wall of frontal horns of lateral ventricles Posteroinferiorly - Corpus and columns of the fornix Superiorly - Inferior surface of the body of the corpus callosumĪntero-inferiorly - Superior surface of the genu of the corpus callosum Both are not parts of the ventricular system as they have a different embryological origin and lack a lining with ependymal or choroid plexus cells. CSP and CV were respectively and incorrectly called the fifth and sixth ventricles in the past. Sometimes, it may connect to a more posterior cavity called cavum vergae (CV), but separates from each other by an arbitrary vertical plane formed by the columns of the fornix. It contains a filtrate of cerebrospinal fluid transferred from the ventricles through the septal laminae, and it does not communicate with the subarachnoid space. The cavum septum pellucidum (CSP) is a potential cavity between the membranous leaves of the septum pellucidum, separated by at least 1 mm, and is considered a normal anatomical variation. It extends between the anterior portion of the corpus callosum, and the body of the fornix and its width varies from 1.5 to 3.0 mm The septum pellucidum (meaning translucent wall in Latin - SP), also known as the ventricle of Sylvius, is a thin, triangular double membrane separating the frontal horns of the right and left lateral ventricles of the brain. This activity reviews the cause and presentation of cavum septum pellucidum and stresses the importance of an interprofessional team in its management. It extends between the anterior portion of the corpus callosum and the body of the fornix, and its width varies from 1.5 to 3.0 mm.
