Validación cuestionario para diagnóstico de ojo seco

Zusammenfassung

Purpose To develop and evaluate a questionnaire for diagnosis and follow-up of patients with symptoms suggestive of eye surface pathology. To evaluate the efficacy of dry eye treatment. Methods Samples were chosen among dry eye patientes (n=44). A control group was chosen among the healthy population. The questionnaire was filled in at the beginning and end of the treatment with carbopol + polivinyl alcohol (Siccafluid®, Thea, Spain) four times a day. Initial and final punctuation was established and confronted with other classic diagnostic tests; fluorescein tear break up time, Schirmer test and Rose Bengal staining. Results Red eyes, lid inflammation, discharge, dry eye, sandy and foreign body sensations, burning, itching, discomfort, pricking, tearing and photophobia got significantly better after reatment (p<0.05). Lid reddening, lid inflammation, flakes in lashes, sticky eyes in the morning, teary eyes, transitory blurring bision and heavy sensation didn't improve (p>0.05). Total punctuation was significantly reduced at one month of treatment (p<0.01). Validation of the test was done against other standard tests (Schirmer test and Rose Bengal). We found a sensitivity of 76% and specificity of 71.5% for Schirmer test and a sensibility of 77% and specificity of 65% if gold pattern was Rose Bengal. Predictive value (positive and negative), global value of the test and likehood ratios were also assessed. Conclusion This questionnaire is useful for diagnosis and follow-up of patients with dry eyes and other ocular surface symptoms. Carbopol + polivinyl alcohol is useful for the treatment of patientes with secretor tear insufficiency (Arch Soc Esp Oftalmol 2002; 77: 493-500).
