The patient presented 2 hours after sustaining a left eye injury caused by a stick. Visual acuity in the left eye was 0.2 without improvement upon correction, and intraocular pressure measured 15 mmHg. Examination of the anterior segment revealed ciliary conjunctival injection accompanied by patchy subconjunctival hemorrhage. The corneal surface remained smooth, and the anterior chamber was deep with hyphema characterized by blood-tinged aqueous humor predominantly settled inferiorly. The pupil was slightly irregular, approximately 3 mm in diameter, with a superotemporal notch; pupillary light reflex was intact. The lens appeared clear. Fundus examination showed well-defined optic disc margins with normal coloration and a cup-to-disc ratio of 0.2. Retinal arteries and veins were normally distributed with an artery-to-vein ratio of 2:3. At the posterior pole, the foveal reflex exhibited concentric ripple-like changes centered on the fovea, accompanied by localized pigment attenuation and reduced reflex intensity. Irregular reflectivity was noted in the superotemporal and inferotemporal nerve fiber layers.

Macular Coloboma found in a 28 year-old male patient, visual acuity was 20/60. Resulting due to fusion failure of the optic fissure, colobomas are commonly found in the infero-nasal quadrant. If the retina is involved, it is reduced to glial tissue with no underlying RPE or choroid. This appears as an area of whitening often with pigment deposition at the junction of the coloboma and normal retina. Findings were bilateral.

A 45-year-old male presented with diminished vision for one month. His Mantoux test was negative, but as steroids worsened the condition, quantiferon TB was advised and it returned positive. He was started on anti-tuberculosis treatment (ATT). Oral steroids were reintroduced after one week of ATT. Optic disc granulomas can arise from direct invasion of the optic nerve or may represent hypersensitivity reaction to tuberculous antigens. The pathogenesis involves infiltration of immune cells, leading to formation of a granulomatous structure that disrupts normal architecture and function of the optic disc. Steroids with ATT facilitated regression of granulomatous lesion.

This is a fundus picture of a young 42-year male who visited for a routine eye exam. His BCVA was 20/20 in both eyes. Anterior segment examination was normal. His left eye showed grey-black pigmentation at the infero-nasal margin of the optic disc. Fundus of the right eye was normal. The patient was diagnosed to have optic disc melanocytoma on multimodal imaging and was advised regular follow-up. Optic nerve melanocytoma is typically a benign tumor made up of melanocytes and melanin. It can grow, but rarely transforms into a malignancy. Patients with Optic Nerve Melanocytoma should be periodically examined for evidence of growth, loss of visual field and optic nerve compression.

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.

This is the fundus picture of right eye (RE) of a 4 years female child presented with outward deviation of right eye. Her parents also complained of diminution of vision in both eyes. On examination, her best corrected vision in RE was hand movements close to face and was 20/80 in LE. Posterior segment exam revealed presence of macular scar in RE and presence of dry retinal fold with dragging of retinal vessels. LE fundus revealed presence of nasal drag of optic disc. Parents gave history of untreated ROP as an infant. Retinopathy of Prematurity (ROP) is a Vaso proliferative disorder of Retina occurring in premature infants. Advances in neonatal care and ROP treatment has led these babies to live longer with this disease.
