Abstract
BACKGROUND: Mitochondrial disease often manifests with ophthalmologic signs and symptoms. Due to the important role of mitochondria in aerobic metabolism, the eyes are among the more preferentially involved organs. The clinical diagnosis of mitochondrial disease can be facilitated by an improved knowledge of the types and magnitude of their various manifestations. The aim of this study was to describe the ophthalmological manifestations of patients with mitochondrial diseases that are currently not well elucidated. METHODS: From a database of patients with verified primary mitochondrial disease (n = 81) who had visited our institution we identified 74 patients who had ophthalmologic examinations. Demographic, clinical, and ophthalmologic data were collected. Institutional review board approval was obtained. RESULTS: A total of 74 patients were identified with Leigh disease, MELAS, MERRF, CPEO, Pearson/Kearns-Sayre syndrome, as well as other mtDNA point mutations, deletions, depletions, and mutations. Overall, 26 of the 74 patients (35%) had one or more ophthalmological abnormalities. Retinal pigmentary changes were present in 12/74 (16%) of patients. Partial or total optic atrophy (OA) was noted in 8/74 (10%) of patients. Decreased extra-ocular movement (EOM) was noted in 6/74 (8%) of patients. Other ophthalmological findings included macular atrophy (2/74), macular dystrophy (1/74), and visual field defects (1/74). CONCLUSIONS: Over one-third of our cohort of patients with mitochondrial disorders had ophthalmological manifestations, some of which affected vision significantly. Eye examinations are critical in patients with mitochondrial disease so that complete assessments of the effects of the underlying mutations are uncovered and the appropriate counseling and care are given.
