A 27-year-old male patient, medically free, presented with unilateral left optic disc swelling. BCVA=1.0(OU), color vision, and contrast sensitivity were normal (OU) with no RAPD in the left eye. SS-OCT: showed left optic disc elevation with hyporeflective mass lesion (Fig-1 B). Enface OCT: showed left peripapillary hyperreflective ovoid mass lesions(Fig-2 D, Fig-3 F), FAF: showed left superonasal hyperautofluorescent drusenoid lesions. Orbital MRI with contrast was requested to exclude any optic nerve compressive lesions like (tumors: like mengioma or inflammatory lesions like granuloma (sarcoidosis). the result of orbital MRI was normal.

27-year-old male, medically free, presented with left unilateral optic disc swelling. BCVA=1.0(OU), color vision, and contrast sensitivity were normal (OU)with no RAPD in the left eye. Swept Source OCT: showed elevated left optic disc with hyporeflective mass (Fig-1 B). Enface OCT: Showed left peripapillary multiple ovoid mass lesions(drusen) (Fig-2 d, Fig3 F). FAF: of the left eye showed superonasal hyper autofluorescent drusenoid lesions)(Fig3 E). Orbital MRI with contrast was requested to exclude any compressive lesions like tumors(menigioma)or inflammatory lesions like granuloma(sarcoid granuloma). orbital MRI result was normal.

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.

27-year-old male, medically free, routine fundus examination showed left optic dic swelling, BCVA =1.0(OU), color vision, and contrast sensitivity were normal with no RAPD (OU). SS-OCT of the left optic disc showed a hyporeflective mass. Enface OCT shadogram showed peripapillary ovoid structures (drusen).FAF: showed drusenoid autofluorescence in the superonasal part only. Orbital MRI with contrast was requested to exclude any optic nerve tumor and it was normal.
