According to the World Health Organization, glaucoma is the leading cause of irreversible blindness worldwide. Although intraocular pressure (IOP) is not considered any more to be a defining feature of the disease, its lowering remains the only treatment option for glaucoma. Therefore accurate and precise measurement of IOP is the cornerstone of glaucoma. Intraocular pressure is a highly dynamic physiological parameter with individual circadian rhythms. The main limitation of current tonometry methods remains the static and mostly office-based nature of their measurements.
To evaluate the safety and efficacy of (0.01%) topical atropine in controlling the progressive myopia in children. Materials and Methods: Clinical study entitled as Placebo-controlled, safety and efficacy study of (.01%) topical atropine in children with progressive myopia. In this prospective case control study 80 children with regular follow-up were divided into a subgroup of 40 children who received atropine eyedrops (0.01%) every night, and a subgroup of 40 children, who remained untreated, served as controls. The changes in refraction and axial length of 160 eyes in 80 children were collected and compared for patients treated with 0.01% atropine eyedrop and those with 0.5% carboxymethylcellulose eye drops (control) at 6 months, 12 months and 24 months. The initial spherical equivalent of refractive status range was between -1.5 and -14.25 DS. Result: Mean myopia progression for the group of patients treated with 0.01% atropine eye drop was -0.34 ± 0.43 DS/year, significantly lower than that of the control group of -1.08 ± 0.57 DS/year and axial length 0.12+0.23mm/year (cases)compared to controls 0.48+0.29mm/year with p value <0.05. Conclusion: 0.01% atropine is effective in controlling progression of myopia in children age group 5-16 years with no side effects.
Checking of intraocular pressure (IOP) is one of the basic investigations in a general ophthalmology work up. In this study we attempted to compare the IOP readings obtained by Goldmann applanation tonometer and Schiotz indentation tonometer in glaucomatous and normal individuals attending general ophthalmology OPD in a tertiary care centre in Central Rajasthan. It is a case series study in which IOP was checked in patients using two tonometers. Statistical analysis was done to evaluate the agreement between instruments.: In this study, when measured with Goldmann applanation tonometer (GAT), it was found that the mean IOP of both right and left eye in group A (Glaucomatous subjects) (24.19±12.94 and 23.34±13.73 respectively) was significantly higher than mean IOP of both right and left eye in group B(non glaucomatous subjects) (15.06±2.49 and 15.12±2.38 respectively). Likewise, when measured with Shiotz tonometer (ST), mean IOP of both right and left eye in group A (26.05±11.93 and 24.65±12.28 respectively) were very significantly higher in comparison to group B (16.79±2.64 and 16.85±2.47 respectively).The mean pressures obtained by the Schiotz tonometer were higher than the mean Goldmann pressures which indicate that the Schiotz tonometer tends to read higher than the Goldmann tonometer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
