Summary
Inflammatory cells in the anterior vitreous (vitritis) were found in some pediatric retinal degenerations, like Bardet-Biedl syndrome, but not others, such as congenital stationary night blindness. This suggests inflammation may accompany progressive vision loss in certain subtypes.
Area of Science:
- Ophthalmology
- Genetics
- Immunology
Background:
- Pediatric retinal degenerations are a diverse group of inherited disorders.
- Inflammation, or vitritis, has been anecdotally observed in some cases but not systematically studied in pediatric retinal degenerations.
- Understanding the role of inflammation in these conditions is crucial for diagnosis and potential treatment.
Purpose of the Study:
- To investigate the association between inflammatory cells in the anterior vitreous and specific types of pediatric retinal degenerations.
- To determine if the presence of vitritis correlates with disease progression or specific genetic diagnoses.
Main Methods:
- Retrospective chart review of pediatric patients with suspected retinal degeneration.
- Slit-lamp examination of anterior vitreous (SLAV) for cell grading and counting.
- Correlation of cell presence with clinical and molecular genetic diagnoses, and visual acuity.
Main Results:
- Of 68 patients with SLAV data, 32.4% showed inflammatory cells (1+ or greater).
- Vitritis was frequently observed in Bardet-Biedl syndrome (BBS) and Leber congenital amaurosis (LCA).
- Inflammatory cells were absent in congenital stationary night blindness (CSNB) and blue cone monochromacy.
Conclusions:
- A subset of pediatric retinal degenerations exhibit vitritis, suggesting inflammation is a feature of specific disease subtypes.
- The presence or absence of vitritis may help differentiate between progressive (e.g., BBS) and stable (e.g., CSNB) retinal degenerations.
- Slit-lamp examination of the anterior vitreous may aid in the clinical diagnosis of pediatric retinal degenerations and identify potential targets for anti-inflammatory therapies.

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...

At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...
