EVALUATION OF TEAR FILM STABILITY IN MIGRAINE
Aim: To evaluate and compare the tear film instability in different types of migraine and rule out the debilitating factors of tear film instability affecting migraine.
Material and methods: A cross sectional study design was used to conduct study at Madina Teaching Hospital Fasilabad. The duration of the study was from September 2021 to June 2022. By using non probability sampling technique 100 participants diagnosed with migraine were included with age range from 25 to 35 years. The participants were divided into two groups. All the participants who fulfill the inclusion criteria were enrolled in study after informed consent. A detailed history was evaluated. Self-design proforma was used for demographic data. For assessing tear film instability Schirmer test and OSDI questionnaire were used and scores were calculated. The statistical analyses were done by using independent sample t-test and Chi-square test.
Results: The results showed that there were moderate level of tear film instability in migraine and there was no significant difference in tear film instability in both types of migraine with mean 8.480 in migraine with aura and 8.670 in migraine without aura with p = 0.799.
Conclusion: It was concluded from the present study that patients suffering from migraine headache are likely to diagnose with tear film instability and according to severity levels there were greater chances of moderate level tear film instability in both types of migraine.
