목적 : To evaluate the effect of optic disc torsion on the progression of glaucoma in young myopic subjects.
방법 : The study included twenty young myopic glaucomatous appearing patients (age range, 20–50 years) with unilateral torsional eyes who were followed for more than 2years. The disc torsion was estimated on red-free RNFL photographs and defined as the degree more than 15’. A comparison was performed between torsional eyes and contralateral normal eyes in terms of rates of change of VF. Clinical factors associated with rapid VF progression were also investigated.
결과 : Mean F/U duration was 3.91±1.38 year. The mean degree of optic disc torsion was 18.10±2.65’ in the torsional eyes and 8.15±3.56’ in the contralateral normal eyes. Initial VF MD value in the torsional eyes(-3.11±4.77) was significantly lower than that of the normal contralateral eyes(-1.85±3.57). However, the torsional eyes and contralateral normal eyes did not differ significantly in the mean progression rate of VF MD value (0.01±0.29 and -0.05±0.30). A Cox proportional hazard model revealed that thin inferior RNFL thickness was significantly associated with disease progression.
결론 : The severity of Visual field defect in young myopic eyes with optic disc torsion was significantly greater than that of contralateral eyes without optic disc torsion. However, the optic disc torsion was not associated with glaucoma progression.
