Anophthalmia Anophthalmia Definition. Anophthalmia, also referred to as Anophthalmos, is a congenital defect that leads to absence of the eyes in a newborn. It is a very rare condition characterized by the lack of the ocular tissue and the globe of the eye. This defect can occur both unilaterally (affecting one eye) and bilaterally (involving both eyes).

Developmental venous anomaly Developmental venous anomaly. Dr Henry Knipe ◉ and Dr Donna D'Souza et al. Developmental venous anomaly (DVA) , also known as cerebral venous angioma, is a congenital malformation of veins which drain normal brain.They were thought to be rare before cross-sectional imaging but are now recognised as being the most common cerebral vascular malformation, accounting for ~55% of all such lesions.WI is the preferred sequence in venous anomalies and proved to have better detectability of venous structures than conventional T2*-weighted imaging. Signals on SWI are not compromised by low-velocity venous flow. Therefore, SWI has successfully demonstrated low-flow vascular formations such as DVA.

- The beginning of the optic nerve in the retina is called the optic nerve head or optic disc. Since there are no photoreceptors (cones and rods) in the optic nerve head, this area of the retina cannot respond to light stimulation.As a result, it is known as the blind spot, and everybody has one in each eye.ptic atrophy of the optic disc (visible to an eye doctor looking inside the eye) is the result of degeneration of the nerve fibers of the optic nerve and optic tract. It can be congenital (usually hereditary) or acquired.

- ABSTRACT - Three cases of an unusual congenital anomaly of the spinal column, anterior sacral. meningocele, are reported. A brief review of the literature and discussion are presented. Anterior sacral meningocele is an unusual. anomaly consisting of a spinal fluid-filled sac in. the pelvis which communicates via a narrow. neck with the spinal subarachnoid space. This. sac is composed of outer dural tissue and inner. arachnoid membrane. Herniation of the dura.

- Video Endoscopic Sequence 1 of 1. Ectopic opening of the common bile duct (CBD) into The Duodenal Bulb. Small hole of which bile emerges at anterior wall of duodenal bulb. The GI tract is an extremely rare congenital anomaly. The clinical implications and frequency of this anomaly are not clearly known. Although an ectopic opening of the CBD is rare, it may be associated with severe pancreaticobiliary disorders.

- Congenital disorder, also known as congenital disease, birth defect or anomaly, is a condition existing at or before birth regardless of cause. Of these diseases, those characterized by structural deformities are termed congenital anomalies and involve defects in a developing fetus. Birth defects vary widely in cause and symptoms. Any substance that causes birth defects is known as a teratogen.

Septo optic dysplasia Septo-Optic Dysplasia is defined by three characteristics: underdevelopment of the optic nerve (visual impairment), abnormal formation of structures along the midline of the brain (abnormal brain development), and pituitary hypoplasia (deficiency of essential hormones). Common symptoms reported by people with Septo Optic Dysplasia.

The Differential Diagnosis of an Optic Nerve Disorder In cases of true optic disc edema, it should be determined if disc. swelling and optic nerve dysfunction are unilateral or bilateral. The most common causes of unilateral optic disc edema are. nonarteritic anterior ischemic optic neuropathy (AION), optic. neuritis (termed papillitis when disc swelling is present), and.

Congenital Nystagmus (Infantile Nystagmus) Congenital nystagmus (also known as infantile nystagmus) is a clinical sign that may take many different forms. Involuntary, rhythmic eye movements are characteristic, as they are in acquired nystagmus. Waveform, amplitude, and frequency can vary with changes in focal distance, direction of gaze, and under monocular or binocular viewing conditions.

Background Optic atrophy is the final common morphologic endpoint of any disease process that causes axon degeneration in the retinogeniculate pathway. Clinically, optic atrophy manifests as changes in the color and the structure of the optic disc associated with variable degrees of visual dysfunction. Optic atrophy is actually a misnomer; in the strict histologic definition, atrophy refers to involution of a structure resulting from prolonged disuse.

Collie Eye Defect in Dogs Collie Eye Anomaly in Dogs. Collie eye anomaly, also referred to as collie eye defect, is an inherited congenital condition. The chromosomes that determine the development of the eyes are mutated, so that the choroid (the collection of blood vessels that absorb scattered light and nourish the retina) is underdeveloped.

Birth defect Congenital disorder, also known as congenital disease, birth defect or anomaly, is a condition existing at or before birth regardless of cause. Of these diseases, those characterized by structural deformities are termed congenital anomalies and involve defects in a developing fetus.bout 3% of newborns have a major physical anomaly, meaning a physical anomaly that has cosmetic or functional significance. Physical congenital abnormalities are the leading cause of infant mortality in the United States, accounting for more than 20% of all infant deaths.

Congenital spinal canal stenosis By Michael Perry, M.D. Congenital spinal canal stenosis describes the narrowing of the spinal canal due to a birth defect. Although most spinal stenosis is a result of degeneration brought on by the aging process, some people inherit traits at birth that lead to congenital spinal canal stenosis. These inherited traits can be extreme, such as severe lordosis or kyphosis (spinal curvature) through scoliosis or dwarfism (achondroplasia).
