The **myelinated nerve fibers of the optic disc** (also known as **medullated nerve fibers**) are retinal nerve fibers that retain their myelin sheath as they pass through the optic nerve head. Normally, retinal nerve fibers are unmyelinated to allow for light transparency, but in some cases, myelination extends anteriorly into the retina, appearing as a striking white, feathery patch on the optic disc or peripapillary retina. ### **Key Features:** 1. **Appearance:** - Dense, white, striated patches with feathery edges. - Typically located at the superior or inferior pole of the optic disc. - May obscure retinal vessels underneath. 2. **Clinical Significance:** - Usually **benign** and asymptomatic. - **Congenital** (present at birth or early childhood). - Rarely associated with **visual field defects** (e.g., scotomas corresponding to the area of myelination). - Occasionally linked with **high myopia** or **amblyopia** if extensive. 3. **Pathophysiology:** - Failure of oligodendrocytes or Schwann cells to stop myelination at the lamina cribrosa. - Normally, myelination stops at the optic nerve head, but in this condition, it extends into the retina. 4. **Diagnosis:** - **Fundoscopy:** Classic white, feathery appearance. - **Optical Coherence Tomography (OCT):** Shows thickened retinal nerve fiber layer (RNFL). - **Visual Field Testing:** May detect defects if large. 5. **Differential Diagnosis:** - Optic disc edema - Cotton wool spots - Retinoblastoma (rarely, but must be ruled out in children) 6. **Management:** - No treatment required if asymptomatic. - Monitor for amblyopia in children. - Rare cases with significant visual impairment may need further evaluation. ### **Fun Fact:** Myelinated nerve fibers are seen in **~0.5-1%** of the population and are usually an incidental finding.

Optic disc pits are rare congenital abnormalities of the optic nerve head. Colour fundus image of an asymptomatic 18-year old male shows an optic disc pit in the right eye (A, white arrow); a small, grey, oval shaped excavation in the temporal segment of the optic disc. These pits are usually unilateral (B shows normal colour fundus of left eye) and asymptomatic. Imaging with optical coherence tomography (C) shows the optic disc pit in cross section (white arrow) and normal macular structure. In some patients with the condition, fluid can accumulate underneath the macular (serous macular detachment).

This is the fundus fluorescein angiography (FFA) of the left eye of a 62-year-old diabetic patient with proliferative diabetic retinopathy and neovascularization of disc who bled from the disc while he was undergoing an FFA procedure. The bleed from the disc gives the appearance of a cannonball fired from a cannon hence the caption "Optic Nerve Head Cannonball".

A 32-year-old woman with a history of drug abuse was admitted due to acute manifestation of multiple infarcts, including acute stroke, splenic and renal infarcts, and multiple cutaneous hematomas. Due to decreased vision in her left eye the patient was referred for ophthalmic evaluation. On exam, visual acuity was 6/10 in the right eye and no light perception in her left eye. Ophthalmoscopic examination was normal in the right eye but showed pallor of the optic nerve head with attenuated retinal vessels in the left eye. Fluorescein angiography showed an oval area of hyperfluorescence from from non-perfusion involving the macular center with staining of overlying retinal capillaries.

Female patient, 37 years old, Caucasian, with complaint of low lateral stroke in abos the eyes. In the retinal mapping examination and retinography, important alterations in the optic nerve head suggestive of DRUSAS DE PAPILA were observed. After being confirmed in the Autofluorescence examination, we observed Autohyperfluorescence compatible with deposits of calcified hyaline material, as well as another complementary exam such as USG and OCT.
