INTRODUCTION: Hereditary optic neuropathies (HON) often begin in adulthood. However, some of them can have an early onset. These may have specific clinical features and natural histories.
PATIENTS AND METHODS: Retrospective study of HON patients with onset before the age of 14 years seen in a referral center. In addition to the age of onset, we evaluated the genetic etiology, visual acuity at 15 years, last best corrected visual acuity, optic disc appearance, visual field and extra-ophthalmological manifestations.
RESULTS: Forty-four patients (16 women) were included; i.e. 27.8% of all patients followed for HON. The mean age of onset was 8.5±3.3 years, with an onset earlier than 3 years in 5 patients. An etiology was not found in 8 patients. Of the remaining 36 patients, 12 had Leber's hereditary optic neuropathy (LHON), 11 had dominant optic atrophy, 12 had WS/WS-like syndrome, 2 had recessive optic atrophy and 1 had spastic paraplegia type 7. For 78 eyes of 40 patients (mean age 26.9±14.5 years), the mean last visual acuity was 0.80±0.33 LogMAR, with differences according to genetic forms. Visual acuity was less than or equal to counting fingers for 7 eyes (29.1%) of 4 WS/WS-like patients and one LHON patient.
CONCLUSION: Early onset NOH are not unusual. Their visual prognosis is as severe as adult onset NOH, with variations depending on the underlying genetic causes.
