Widefield fundus photograph of a 37 year old showing a large, dome-shaped, intraocular mass involving the temporal retina. The lesion appears elevated and lacks surface pigmentation. Overlying retinal vessels are displaced and draped across the tumor surface, with surrounding retinal elevation noted. The appearance is suggestive of amelanotic variant of choroidal melanoma.

Fundus photograph of left eye showing Cytomegalovirus retinitis of a 40-year-old male with positive HIV history. He presented with CD4 cell count of 50 cells/mm3 and decreased vision of left eye. In the photograph we can see the three typical patterns in this retinitis: a hemorrhagic appearance in superior temporal arcade and between nasal arcades, granular pattern in superior temporal retina, and a “frosted branch” angiitis surrounding the retinal vessels in nasal and superior retina.

60-year-old white female presented with five days of acute vision loss in the right eye. She was seen initially by referring doctor after hours five days ago and diagnosed with a CRAO and sent to ED to be evaluated stroke team. Right ICA was 100% closed but completely bypassed. She called four days later c/o redness and eye pain; at this point prominent iris vessels were seen, and she was sent to us. Her background history includes a diagnosis of moyamoya (underwent bilateral cerebral artery bypass 2015); atorvastatin for hypercholesterolemia; ASA; no hx of HTN or heart disease. She had a scleral buckle repair OD in 2017 and later developed a thick ERM, which was repaired in 2018; on her previous visit her acuity was noted at 20/40. On presentation her visual acuity was HM OD and 20/15 OS. IOP was 8 OD and 10 OS. There were prominent iris vessels in the right eye, no cell or flare, and an IOL. The posterior segment exam showed diffuse retinal whitening with attenuated vessels and boxcarring; there was sparing retinal whitening in a central area of the macula that appeared to be supplied by a cilio-retina artery. The FA showed very slow filling of the retinal vessels; there was some early perfusion secondary to the cilio-retinal artery. At 7 minutes there was still significant areas of non-perfusion, as well as macular ischemia. Avastin was administered, and one week later, PRP was performed. On the day PRP was performed, the irregular iris vessels had regressed completely. She said that she had a "sliver" of vision centrally in that eye; her acuity was CF 2' and IOP 12.

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.

Video of the fundus of the left eye of a 14-year-old asymptomatic female, where a prepapillary vitreous opacity is observed. The opacity is attached to the origin of the retinal vessels in the optic nerve head, and is considered to be a remnant of the hyaloidal artery.

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.

Intraoperative fundus picture of right eye of a 18-year-old boy with complaints of DOV for the past 2 months. There were 12 intravitreal cysts in total with vitritis sclerosis retinal vessels and TRD. To note here, the largest cyst has a flimsy wall and no scolex (possibly ruptured) and the rest of the smaller cysts have a scolex and a taut wall.
