AI Article Synopsis

  • The study examines how different genotypes of Leber hereditary optic neuropathy (LHON) affect visual prognosis.
  • A systematic review of ten studies revealed significant differences in visual outcomes between the three primary mutations of LHON.
  • Despite variations in prognosis, factors like age of onset and sex ratio showed no significant differences among the genotypes.

Article Abstract

Aim: To analyze the influences of different genotypes (, and ) of Leber hereditary optic neuropathy (LHON) on visual prognosis.

Methods: After a systematic literature search, all relevant studies evaluating the association between the three primary mutations of LHON and visual prognosis were included. All statistical tests were calculated with Revman 5.2 and STATA 12.0.

Results: Ten independent studies were included finally. A significant association between the three primary mutations and prognostic vision over 0.3 were found in versus [odds ratio (OR)=0.10, 95% confidence interval (CI)=0.05-0.17, <0.001], versus (OR=0.18, 95%CI=0.09-0.37, <0.001) and versus (OR=2.45, 95%CI=1.10-5.48, <0.05). In addition, obtained by pairwise comparison, the vision during onset, age of onset and sex ratio of these three kinds of patients, have no statistical significance (>0.05).

Conclusion: From pairwise comparison, we conclude that these three different genotypes of LHON are related to patients' visual prognosis. The patients might have a best prognostic vision, second, and worst. And there is little relation between the three different genotypes and patients' vision, age of onset and sex ratio.

Inherited retinal diseases (IRDs) are a clinically and genetically diverse group of progressive degenerative disorders that can result in severe visual impairment or complete blindness. Despite their predominantly monogenic inheritance patterns, the genetic complexity of over 300 identified disease-causing genes presents a significant challenge in correlating clinical phenotypes with genotypes. Achieving a molecular diagnosis is crucial for providing patients with definitive diagnostic clarity and facilitating access to emerging gene-based therapies and ongoing clinical trials.

Article Synopsis
  • Inherited retinal dystrophies (IRDs) are a significant cause of blindness or severe visual impairment in children, with varying symptoms and genetic associations.
  • The study analyzed data from 309 pediatric patients to determine the clinical and genetic profiles of IRDs, finding distinct patterns in preschoolers versus school-aged children.
  • Preschoolers exhibited symptoms like nystagmus and established genetic variants linked to isolated and syndromic forms of IRDs, while school-aged children largely showed declining visual acuity and a higher prevalence of cone-dominated diseases.
