AI Article Synopsis

  • Neonatal protein C deficiency can lead to severe conditions like purpura fulminans and has a generally poor prognosis, especially regarding vision.
  • In a study of 38 survivors with biallelic PROC variants, a significant number suffered from severe visual impairments: 23 were totally blind, and only one had normal vision.
  • Prenatal intervention is crucial to enhance visual outcomes, as ocular lesions often present early in these cases, affecting the eyes before other organs.

Article Abstract

Neonatal protein C (PC) deficiency, which presents with purpura fulminans or hemorrhagic infarction, has a poor prognosis. In a sporadic case of prenatal-onset purpura fulminans, preemptive intervention saved the patient but not her vision. Among 38 survivors from 47 cases with ocular lesions and biallelic PROC variants, 23 had total blindness and eight had unilateral blindness. Only one had intact vision. Prenatal-onset ocular lesions occurred in 11 cases (29% [corneal opacities, n = 7; bilateral persistent hyperplastic primary vitreous, n = 1; both, n = 3]). The eyes are the first organ affected by heritable severe PC deficiency. Prenatal intervention is needed to improve visual outcomes.

Background: Alport syndrome (AS) is a multifaceted condition that primarily affects the basement membranes of the kidneys, ears, and eyes. AS is considered the second most common cause of hereditary renal failure, exhibiting varied clinical manifestations across different lifespans. The aim of this study is to investigate the clinical features and genetic profile of AS and to elucidate the genotype-phenotype correlation of AS.

The protozoan Toxoplasma gondii is a ubiquitous and highly prevalent parasite that can theoretically infect all warm-blooded vertebrates. In humans, toxoplasmosis causes infections in both immunodeficient and immunocompetent patients, congenital toxoplasmosis, and ocular lesions. These manifestations have different degrees of severity.

Article Synopsis
  • PAH can cause serious ocular conditions like CRVO and CilRAO due to high blood pressure in the lungs affecting blood flow to the eyes.
  • A 13-year-old girl with a history of heart surgery experienced sudden vision loss, with tests revealing both CRVO and CilRAO, along with signs of severe PAH.
  • Treatment with Bosentan and traditional Chinese medicine led to significant vision improvement, highlighting the importance of addressing cardiovascular issues to prevent eye complications and the need for a comprehensive approach in such complex cases.

Neurofibromatosis type 1 (NF1) is an autosomal dominant genetic multisystem phakomatosis that can affect the skin, bones, and nervous system. NF1 typically presents with skin lesions, including freckles, café-au-lait macules, plexiform neurofibromas, and bony dysplasia, and is usually accompanied by a family history of the disorder. Ocular manifestations vary, but iris Lisch nodules and optic nerve gliomas are the most common features.

Conjunctival malignant melanoma is extremely rare, with no standard of care established at moment. Here we report a 65-year-old woman, as a hepatitis B virus (HBV) carrier, who presented concurrently a liver mass and lower bulbar conjunctival pigmented lesions in the right eye. Needle liver biopsy and excisional conjunctival biopsy showed hepatocellular carcinoma and conjunctival malignant melanoma , respectively.
