Kearns-Sayre syndrome (KSS) belongs to the group of neuromuscular disorders known as mitochondrial encephalomyopathies. It has characteristic syndromal features, which include: chronic progressive external ophthalmoplegia, bilateral atypical pigmentary retinopathy, and cardiac conduction abnormalities. So far, only a single case has been reported where a patient with KSS had a normal retina. Herein, we report this extremely rare variant of KSS, which not only presented later than the normal age of presentation, but also had minimal pigmentary retinopathy.

Syndromic Retinitis Pigmentosa.

Retinitis pigmentosa (RP) is a progressive inherited retinal dystrophy, characterized by the degeneration of photoreceptors, presenting as a rod-cone dystrophy. Approximately 20-30% of patients with RP also exhibit extra-ocular manifestations in the context of a syndrome. This manuscript discusses the broad spectrum of syndromes associated with RP, pathogenic mechanisms, clinical manifestations, differential diagnoses, clinical management approaches, and future perspectives.

Anti-VEGF therapy for proliferative diabetic retinopathy in Kearns-Sayre syndrome.

Save Sight Institute Faculty of Medicine and Health, University of Sydney, Sydney, Australia.

Purpose: Multiple mitochondrial syndromes, such as Kearns-Sayre, involve the concurrence of diabetes mellitus and inherited pigmentary retinopathy. It is rare, however, for proliferative disease to develop in these patients as existing inner retinal dysfunction is thought to be protective.

Methods: To our knowledge this is the first description of proliferative diabetic retinopathy (PDR) in Kearns-Sayre syndrome.

Primary mitochondrial disease (MD) is a group of rare genetic diseases reported to have a prevalence of 1:5000 and is currently without a cure. This group of diseases includes mitochondrial encephalopathy, lactic acidosis, and stroke-like episodes (MELAS), maternally inherited diabetes and deafness (MIDD), Leber's hereditary optic neuropathy (LHON), Leigh syndrome (LS), Kearns-Sayre syndrome (KSS), and myoclonic epilepsy and ragged-red fiber disease (MERRF). Additionally, secondary mitochondrial dysfunction has been implicated in the most common current causes of mortality and morbidity, including cardiovascular disease (CVD) and cancer.

Article Synopsis
  • The study assessed the link between inherited mitochondrial dysfunction and neuromuscular junction (NMJ) remodeling in patients with mitochondrial disorders, analyzing muscle biopsies from 15 patients and 10 controls.
  • Results showed that patients with mitochondrial disorders had significantly more remodeled and neoformed NMJ endplates, with a trend towards increased Schwann cell extensions, indicating NMJ alterations even without muscle weakness.
  • The findings suggest that mitochondrial disorders may lead to NMJ remodeling as a primary issue, separate from structural muscle damage, though the exact mechanisms and clinical indicators warrant further investigation.
