Sialidosis

Jul 10 2025 by Jessilla Phou

These are fundus photographs capturing an 18 year old male with Type 1 Sialidosis, a rare inherited lysosomal storage disorder caused by a deficiency in the neuraminidase 1 (Neu1) enzyme. Currently, there are fewer than 1,000 people in the USA who have this disorder. It is characterized by a cherry red spot in the macula which occurs when lipids accumulate in the retinal ganglion cells. This causes the macula to appear red as seen in these fundus images. The patient presented at our office with ataxia, depth perception issues, and slow reaction time. His visual acuity was 20/40, suggestive of early stage Sialidosis.

Pseudoduplication of the Optic Disc

Jul 9 2025 by Hrishikesh Naik, MS

A peripapillary colobomatous pseudo-duplication of the optic disc as seen in an asymptomatic 23 year old female with myopia referred for routine retinal periphery screening. Rest retinal exam was normal. Duplication of the optic disc can be classified as either true duplication or pseudoduplication, both of which are rare clinical conditions. Pseudodoubling of the optic disc is commonly caused by optic disc or peripapillary colobomas, characterized by a circumscribed, disc-like lesion with radiating vessels but only one normal optic nerve. A few cases have involved pathological myopia, moderate myopia, proliferative diabetic retinopathy and CHARGE syndrome. The lesion is often found inferior to the normal optic disc. The patient was advised regular follow ups.

Choroidal Melanoma (USG)

Jul 5 2025 by Gustavo Uriel Fonseca Aguirre

This B-mode transverse ultrasound scan reveals a mushroom-shaped choroidal tumor in the inferior nasal quadrant adjacent to the optic nerve head. The lesion appears solid with homogeneous internal reflectivity and is associated with minimal surrounding subretinal fluid and scleral excavation. It measures 6.54 mm in height × 7.52 mm in base diameter (transverse view) and extends 9.52 mm longitudinally. The vitreous contains abundant punctate opacities consistent with pigment dispersion. The retina and choroid remain attached elsewhere.
