Late effects on the eye of conformation radiotherapy for carcinoma of the paranasal sinuses and nasal cavity

K Morita and Y Kawabe

Sixty patients with carcinoma of the paranasal sinuses and nasal cavity were treated with conformation radiotherapy technique (an improved moving-field technique). Only 28 were suitable for long-term follow-up with regard to eye complications. All patients receiving more than 5,800 rads in 6 weeks (1,700 reu in cumulative-radiation-effect dose) had strong panophthalmia with corneal ulceration within 2 years of radiotherapy. Of 21 eyes receiving 800--1,700 reu (2,800--5,400 rads in 6 weeks), 18 experienced visual disturbance from radiation cataracts and 3 equivocal changes at postirradiation intervals of 5 years. No patient receiving less than 800 reu (2,800 rads in 6 weeks) showed such complications.
