    Abstract:
    OBJECTIVE: To assess subjective symptoms, tear function factors, and ocular surface morphology in the clinical course of patients with dry eye syndrome under treatment within an observation period of up to 8 years. METHODS: In 97 patients (78 women and 19 men) with ocular discomfort, a clinical diagnosis of dry eye syndrome was made based on typical symptoms and a reduced tear film breakup time of less than 10 seconds. Subsequent evaluations revealed a diagnosis of aqueous tear deficiency in 9 patients, meibomian gland dysfunction in 32 patients, and aqueous tear deficiency combined with meibomian gland dysfunction in 30 patients, aqueous tear deficiency associated with Sjögren syndrome in 12 patients, and aqueous tear deficiency and meibomian gland dysfunction associated with Sjögren syndrome in 14 patients. Follow-up assessments were performed 12 to 94 months (mean follow-up, 40 months) after the initial diagnosis. MAIN OUTCOME MEASURES: In different subgroups of dry eye tear film breakup time, Schirmer test without local anesthesia (Schirmer I), fluorescein and rose bengal staining, impression cytology, as well as subjective dry eye symptoms and frequency of tear substitute application were compared at baseline and after a follow-up of 1 to 8 years (mean, 3.3 years). RESULTS: At baseline, tear film function and ocular surface test results found more pathologic abnormalities and more severe subjective symptoms in patients with aqueous tear deficiency associated with Sjögren syndrome and aqueous tear deficiency and meibomian gland dysfunction associated with Sjögren syndrome compared with the other groups who had dry eye syndrome. No differences in frequency of tear substitute application were observed. At follow-up, tear breakup time, Schirmer I test results, and corneal fluorescein staining improved compared with baseline values, whereas rose bengal staining and impression cytology of the conjunctival surface remained almost unchanged. Subjective symptoms and frequency of artificial tear application were reduced. CONCLUSIONS: Within the observation period of up to 8 years, the dry eye syndrome improved or stabilized under appropriate treatment. Although no patient was completely cured, subjective reports as well as frequency of artificial tear application were reduced.
