Clinical Presentation & Protocol
Patient Usually Complains Of
Patient presents with a progressive history of chronic progressive external ophthalmoplegia (CPEO) and pigmentary retinopathy. Onset of symptoms occurred before age 20. Reports associated systemic manifestations including muscle weakness, exercise intolerance, and syncopal episodes suggestive of cardiac conduction defects. No prior history of ataxia or sensorineural hearing loss noted.
Clinical Examination Findings
Physical examination reveals bilateral ptosis and restricted extraocular movements in all gazes. Fundoscopic exam confirms salt-and-pepper pigmentary retinopathy. Neurological assessment demonstrates proximal muscle weakness and gait instability. Cardiovascular exam reveals bradycardia or irregular rhythm; ECG confirms high-grade AV block or bundle branch block. Laboratory findings show elevated CSF protein (>100 mg/dL).
Treatment Protocol
Management requires multidisciplinary approach. Immediate cardiology referral for prophylactic pacemaker implantation due to high risk of sudden cardiac death from heart block. Regular ophthalmological monitoring for retinal degeneration. Supportive therapy includes Coenzyme Q10 and vitamin supplementation. Physical therapy for muscle weakness and regular screening for endocrinopathies.
