Background and Objectives: Raised intraocular pressure is a well-known causative risk factor for the development of glaucoma. It is also the only component of glaucoma that is amenable to medical or surgical intervention, provided it is detected early enough. The measurement of intraocular pressure has evolved over time with the advent of a myriad of newer tonometers – one such being the non-contact tonometer. This study has been embarked upon with the objective of comparing the non-contact tonometer with the gold standard. Goldmann applanation tonometer versus the Schiotz tonometer, one of the most popularly used tonometers in the developing world. It also aims to establish the value of the non-contact tonometer as a screening tool. Materials and Methods: 200 purposively selected patients were subjected to three methods of tonometry; Goldmann applanation tonometry, Perkins Tonometry and Schiotz indentation tonometry (with the 5.5g, 7.5g and 10g weights); on both eyes. Three recordings were obtained with each method and the arithmetic mean taken as the intraocular pressure. The data was statistically analyzed using the intra-class correlation coefficient. Results: The non-contact tonometer showed excellent agreement with the Goldmann applanation tonometer compared to the Schiotz tonometer which showed only a fair agreement. Interestingly, the left eyes showed better agreement on noncontact tonometry than the right eyes, a phenomenon we attribute to apprehension of the patients on their first experience with the air puff. The non-contact tonometer also scored high as an effective screening tool. Conclusion: The non-contact tonometer compares favorably with the Goldmann applanation tonometer and can be reliably used as a screening tool. However, in view of the varying degrees of comparison between the two eyes, its role in monitoring glaucomatous eyes needs to be further evaluated.Keywords

Background: To conduct an effective ROP screening program according to the Indian standard needs and to identify the infants who could benefit from treatment and make appropriate recommendations on the timing of future screening. Aims and Objectives: To estimate the incidence of ROP among Premature infants. Materials and Methods: A Prospective Observational study of 2 years in which 170 patients were screened with following criteria: GA at birth of ≤35 weeks, BW <1700 gms, exposed to oxygen >30days, other factors that can increase the risk of ROP and where screening should be considered are premature babies >37 weeks and >1700gms but with the first screening was done within 4 weeks (30 days) of life in infants with age >28 weeks of GA, 2-3 weeks after birth if GA <28 weeks or BW is <1200gms. Results: Out of the 170 babies screened 35 babies had ROP. Incidence of ROP in our study was 20.59%. The sensitivity of AAP and UKRCPCH guidelines to ours were 77.14% and 60% respectively. Conclusion: ROP may be seen in heavier and larger babies in India that have consequently a shorter window period for development of ROP, Hence, a criteria screening even larger babies should be taken into consideration.
