ABSTRACT
High intraocular pressure is a major risk factor for Glaucoma in Myopic patients. The aim of this study is to study the association between IOP and myopia.METHODSA hospital-based study was done from December 2018 to May 2019 in 150 eyes. Patients in the age group of 10 - 50 yrs. were studied. Patients were divided into four groups according to their refractive status. Group 0- emmetropia (+0.5 D to -0.5 D), Group 1- low myopia (-0.75 to -3.00 D), Group 2- moderate myopia (-3.25 D to-5.00 D) and Group 3- high myopia (>-5.00 D). Examinations like slit lamp, retinoscopy, gonioscopy, fundus examination were done. IOP was measured using Perkins tonometer.RESULTSGroup 0 included 64 eyes, Group 1 included 44 eyes, Group 2 had 26 eyes, and Group 3 had 16 eyes. There is no significant difference in IOP between Group 0 and Group 1 but IOP was found to be higher in Group 2 and 3.CONCLUSIONSThere is significant correlation between intra ocular pressure and high/moderate myopia than with emmetropes and low-grade myopia, thus increasing the chances of glaucoma in patients with high/moderate myopia.
ABSTRACT
Petroleum reservoir is an ecosystem having extreme environmental conditions of temperature, pressure and salinity. They possess highly anoxic conditions. Major microbial communities present in this environment include fermentative bacteria, sulphate reducing bacteria (SRB), syntrophic bacteria and methanogens. Phylogenetic diversity of microorganisms as well as their ecological role play an important role in the petroleum reservoir ecosystem. Past and present efforts to characterize microbial communities in oil field ecosystem by culture or cultivation-dependent and -independent approaches are discussed with highlights of microbial ecology of petroleum oil reservoir ecosystem(s). Novel strategies used to study culture independent diversity of microorganisms using metagenomic techniques have also been narrated.
