![]() After that, infantile retinal hemorrhages are commonly associated with abusive head trauma however, they can occur with other conditions that cause increased intracranial pressure or intracranial hemorrhage, such as accidental trauma or asphyxiation, cerebral venous thrombosis, stroke, and encephalitis. Sub-RPE hemorrhage is located between the retinal pigment epithelium and Bruch membrane. Subhyaloid hemorrhages are located between the internal limiting membrane and the posterior hyaloid membrane. Practical Pointsīirth-related hemorrhages are typically gone by age 1 month. Dot and blot hemorrhages are located in the Outer plexiform layer - Inner nuclear layer (OPL-INL)complex. Severe hemorrhages can cause permanent visual loss. Retinal hemorrhages usually resolve on their own within weeks of diagnosis. Retinal hemorrhages can be seen on MR SWI imaging 2. Usually blood accumulates in the outer plexiform or inner nuclear layers, or more easily seen at. They have been described as dot/blot, boat-shaped, flame-shaped, or splinter-shaped. Dot and Blot Hemorrhage Hemorrhages lie deeper in the retina. Retinal hemorrhages can appear to the ophthalmologist in various shapes depending on the layer(s) of the retina affected. Retinal hemorrhages are usually found in the setting of an acute infantile neurologic problem, such as seizure, lethargy, suspected or known head trauma. The only well-known incidence of infantile retinal hemorrhage comes from neonatal studies, where, in a recent study, 20% of full-term newborns were found to have retinal hemorrhages 1. Another common term used is 'fundus hemorrhage'. It is possible that interferon beta 1a retinopathy is more common than previously reported, as it may be asymptomatic with patients having peripheral retinal hemorrhages.Retinal hemorrhages that are associated with intracranial hemorrhage, usually subarachnoid hemorrhage, are referred to as ' Terson syndrome', as described by Terson in 1900 (he actually described the association between vitreous hemorrhage and intracranial hemorrhage). ![]() The capillary network in the posterior retina is found in two layers a superficial one in the nerve fibre layer and a deeper on within the inner nuclear layer. of eyes 74, 65) resolved within 4 weeks, whereas four babies (8 eyes, 7.4) progressed to ROP were treated with laser. Intraretinal haemorrhages may be ‘dot’ or’ blot’ shaped (termed ‘dot/blot haemorrhages’) or flame shaped depending upon their depth within the retina. She was found to have peripheral dot and blot hemorrhages with no cotton wool spots. Flame-shaped hemorrhages were more common than dot and blot ones. It is possible that interferon beta 1a retinopathy is more common than previously reported, as it may be asymptomatic with patients having peripheral retinal hemorrhages.ĪB - We present a case of retinopathy found incidentally in an asymptomatic patient receiving treatment with interferon beta 1a for multiple sclerosis. She was found to have peripheral dot and blot hemorrhages with no cotton wool spots. N2 - We present a case of retinopathy found incidentally in an asymptomatic patient receiving treatment with interferon beta 1a for multiple sclerosis. T1 - Asymptomatic peripheral retinal hemorrhages as a manifestation of interferon beta 1a retinopathy ![]()
