This image serial demonstrates a patient with simple ectopia lentis. Anterior segment photographs in the upper panel demonstrate nasally subluxated crystalline lenses. Widefield fundus photography shows a "pseudo-buckle" which is the result of an optical effect due to the lens subluxation (artifactual image enlargement). Also note the juvenile macular reflex in this young patient. Ectopia lentis can present isolated ("simple") or in combination with various systemic defects (Marfan's syndrome, Weil-Marchesani syndrome or Ehlers-Danlos syndrome to name a few). Isolated ectopia lentis can be hereditary and causative genes have been identified as ADAMTSL4 located on chromosome 4 and FBN1 gene located on chromosome 15. Defects in the genes cause weakness in the zonular fibers which can lead to lens dislocation. Lastly, various ocular disorders such as Aniridia, Axenfeld-Rieger, Pseudoexfoliation or Trauma may also result in lens dislocation or subluxation.

Sep 7 2022 by JEFFERSON R SOUSA, Tecg.º (Biomedical Systems Technology)

A 63-year-old male patient underwent vitreoretinal surgery with the use of perfluorocarbon. From a technological point of view, extended-field retinography presents many points of focus variation due to the difficulty of establishing a diffuse focus, as it is a recent post-operative case. In OCT Fundus Enface, although it has a low resolution, it is extremely important for documenting the presence of perfluor. Best seen in structural OCT.

Optical coherence tomography and ultra-wide field fundus photograph of a 51 year old male with idiopathic choroidal neovascularization affecting his right eye. The patient had no symptoms at the time of the appointment and his vision was Dcc20/20-2 OU. The physcian stated that there wasn't active exudation on the exam or ocular imaging and based on the clinical findings, he has recommended we defer any treatments.

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).
