摘要

Background: Intra ocular pressure (IOP) measurement is essential in ophthalmological assessment asraised IOP is an important risk factor for development as well as progression of glaucoma. Aims: To correlatethe IOP by the Non Contact Tonometer (NCT) with the Perkins Applanation Tonometer (PAT) and to studyNCT as a screening tool. Materials and Methods: It is a comparative study on Patients attending Out PatientDepartment of Ophthalmology, from 1st December 2014 to 30th September 2016. We included 260 participants.Data collected using proforma, informed consent, history, ophthalmological examination. Patients weresubjected to Non Contact Tonometry and Perkins Applanation Tonometry. 3 readings were taken for eachmethod and mean calculated. Statistical analysis used: Paired-T test & Correlation-co-efficient. Sensitivity andSpecificity were calculated for the NCT. Results: The NCT showed excellent agreement with the PAT. Thecorrelation coefficient(r) of IOP measured by NCT and PAT is 0.879 and 0.894 for right eye and left eyerespectively with p value <0.05, showed strong positive correlation between the IOP measured by NCT andPAT. The NCT also scored high as an effective screening tool. The NCT showed high sensitivity 95.5 and 94.3for right eye and left eye respectively, high specificity 94.5 and 99.1 for right and left eye respectively, comingacross an excellent agreement with PAT, using an IOP of more than/equal to 21 mm Hg with the PAT as thestandard criterion. Conclusion: The current study shows that the NCT compares well with the PAT. The NCTcan be used as a reliable screening tool.
