Drance Hemorrhages!

𝘖𝘱𝘵𝘪𝘤 𝘋𝘪𝘴𝘤 𝘏𝘦𝘮𝘰𝘳𝘳𝘩𝘢𝘨𝘦𝘴⁣ ● Splinter or flame-shaped hemorrhages ● Perpendicular to the optic disc margin⁣ ● Classically, these hemorrhages are located in the prelaminar optic disc, cross the peripapillary zone, and extend into the adjacent superficial retinal nerve fiber layer⁣ ● Disc hemorrhages are a risk factor for progression of glaucoma⁣ ● Most common in normal tension glaucoma⁣ ● Associated with notching of the neuroretinal rim or retinal nerve fibre layer defects⁣

𝐏𝐚𝐭𝐡𝐨𝐠𝐞𝐧𝐞𝐬𝐢𝐬: ⁣ 𝘔𝘦𝘤𝘩𝘢𝘯𝘪𝘤𝘢𝘭 𝘛𝘩𝘦𝘰𝘳𝘺:⁣ .⁣ ● Disc hemorrhages result from mechanical shearing at the lamina cribrosa or because of damage to the capillary network at the border of retinal nerve fibre layer defect enlargement.⁣ ● Primary insult is neurodegenerative, and the hemorrhage is a secondary event resulting from tissue damage.⁣ 𝘝𝘢𝘴𝘤𝘶𝘭𝘢𝘳 𝘛𝘩𝘦𝘰𝘳𝘺:⁣ ● Ischemic microinfarction in the optic nerve head or break down of the blood-retinal barrier.⁣ 𝘓𝘰𝘤𝘢𝘵𝘪𝘰𝘯:⁣ Disc hemorrhages associated with glaucoma are found mostly in the inferotemporal and superotemporal regions of the optic disc⁣ 𝘚𝘺𝘴𝘵𝘦𝘮𝘪𝘤 𝘢𝘴𝘴𝘰𝘤𝘪𝘢𝘵𝘪𝘰𝘯𝘴:⁣ ● Hypertension⁣ ● Vascular disease⁣ ● Migraine⁣ ● Diabetes⁣ ● Aspirin use⁣ ● Smoking⁣ ● Exfoliation syndrome etc.⁣ 𝘛𝘳𝘦𝘢𝘵𝘮𝘦𝘯𝘵:⁣ A disc hemorrhage does not need to be treated but its presence may signal the need for better control of intraocular pressure in glaucomatous eyes.⁣ Image from Rajan Eye Care Hospital #ophthalmology #ophthal #doctor #health #medical #vision #education #optometry #medicalstudent #optometrist #medicine #eye #ophtho #ophthalmologist #ophthalmo #med #medicaleducation #ophthalmologyresident #ophthalmologyresidency #glaucoma #opticdisc #opticdischemorrhage #disc #retina
