초록
목적: 얼렌증후군 환자에게서 색조렌즈를 통한 난독 증상의 개선 여부를 알아보았다. 대상과 방법: 난독증을 호소하는 환자에게 설문조사를 시행하여 2.13점 이상이면서 다른 안과적 이상소견이 없는 25명을 대상으로, 색조렌즈 착용 전후 분당 읽기/쓰기 속도를 측정하였다. 본인에게 적합한 색조렌즈를 선택하여 최소 두 달 이상 착용한 후 최종 만족도를 설문 조사하였다. 결과: 8명(32%)은 청색계열을, 4명(16%)은 회색계열의 색조렌즈를 선택하였다. 난독증 설문조사의 평균 점수는 2.72점이었다. 읽기속도는 색조렌즈 착용 전후 평균 분당 82.72자에서 101.84로, 통계학적으로 유의한 개선이 있었지만(p=0.019), 쓰기속도는 유의한 차이가 없었다. 색조렌즈 착용 두 달 후 종합적인 만족도는 3.6점이었고, 읽기 편함에 대한 주관적인 만족도가 가장 높았고(4.08점), 쓰기 편함에 대한 만족도가 가장 낮았다(2.92점). 결론: 난독증상이 있는 일부 환자들에서는 색조렌즈가 유용한 읽기 개선효과를 나타냈다. 난독증 환자 중에서 얼렌증후군에 비교적 특이적인 안과증상들을 숙지하고, 다른 안과적 질환과의 감별을 위한 안과의사의 진찰과정이 필수적이라고 생각된다.
Abstract
Purpose: To evaluate the benefit of colored filters in Meares-Irlen Syndrome patients with reading difficulties. Methods: Twenty-five patients were selected through a brief questionnaire aimed to determine symptoms of eyestrain or visual distortion after thorough eye examinations. The cutoff value of the questionnaire was 2.13. The rates of Korean reading and writing were measured using the RWSM (Reading Writing Speed Meter) test with and without the use of colored filters. Two months after wearing the individually prescribed colored filters, a questionnaire on the patient’s subjective satisfaction with the colored filters were completed and evaluated. Results: The blue (n = 8, 32%) and gray (n = 4, 16%) colors were the most frequently selected filters. The mean score of the questionnaire on reading difficulties was 2.72. The mean reading rate improved from 82.72 wpm (words per minute) to 101.84 wpm with the colored filters, a statistically significant change (p = 0.019). The mean writing rate did not improve. The overall satisfaction score with the colored lenses was 3.6, with the highest score given to ease of reading (4.08) and the lowest to writing (2.92). Conclusions: In cases of reading difficulty, colored filters were effective for alleviating visual symptoms and improving reading speed. It is important to achieve an adequate understanding of the specific symptoms of Meares-Irlen Syndrome and to perform a thorough eye examination to differentiate this from other ocular disorders.
