Aim & Objective: The purpose of this study is to evaluate prevalence risk factors, symptoms, signs, objective tests of dry eye diagnosis in patients attending to Out Patient Department of Mamata General Hospital, Khammam.
Materials and Methods: All patients presenting with dry eye symptoms to ophthalmology outpatient department, Mamata Medical College over a period of one and half year. A prospective study was conducted for a period of 18 months from June 2018 to Jan 2021 among patients attending ophthalmology Out Patient Department unit with symptoms of dry eye.
Results: Among the 100 patients studied, prevalence of dry eye was found to be as high as 23%.The prevalence of dry eye increased with increase in age and was significantly higher among people more than 40 years of age. Prevalence was higher among females when compared to males. Conjunctival congestion was found to be reliable sign of dry eye with a strong positive association. Foreign body sensation was found to be the most common symptom associated with dry eye. People with refractive errors, with or without history of spectacle use, had a higher incidence of dry eye compared to emmetropes. OSDI was found to be reliable measure of dry eye symptoms. Higher, scores of OSDI, indicating severe dry eye, correlated well with diagnostic tests for dry eye. TBUT test showed a high sensitivity and specificity, followed by Schirmers test and impression cytology. Impression cytology was a reliable measure for detecting ocular surface changes. Many patients showed grade 2 or 3 changes. These changes were more among those with schirmer less than 5mm.
Conclusion: Dry eye evaluation with an appropriate and standard questionnaire along with standard tests for dry eye helps in diagnosis and treatment. This will go a long way in the effective and successful management of patients with dry eye, specially so as the disease is chronic and needs long term treatment. Early and appropriate management will provideocular comfort and satisfaction with a better quality of life.
