Latest Research on Intraocular Pressure: Dec – 2019

Corticosteroids and Intraocular Pressure

Introduction  The finding of γ-globulin associated plasma cells within the fibrous tissue fabric of glaucomatous eyes urged an immunogenic part.1,2 this study was undertaken to work out, underneath controlled conditions, the result of topical corticosteroids within the eye with primary chronic glaucoma.Corticosteroids are incriminated within the exacerbation or production of the glaucomatous state.3-7 Such reports were mostly involved with eye disease occurring throughout the course of inflammation and were troublesome to interpret. [1]

Intraocular Pressure Response to Topical Corticosteroids

The pressure response to topical betamethasone seems to be genetically determined. A study of patients with primary chronic glaucoma, their relatives, eye disease suspects, and volunteers shows 3 populations on degree of responsiveness. it’s instructed that these square measure the phenotypes that relate to the homozygous poor communicator (nn), the heterozygous communicator (ng), and also the homozygous larger communicator (gg). [2]

Marihuana Smoking and Intraocular Pressure

It is accepted wide that the physical effects of smoking marihuana don’t seem to be accepted, despite AN acknowledged high incidence of usage. Even the President of the us has caught up a significant effort to check drug effects in an exceedingly scientific manner. In an endeavor to analyze the results of marihuana smoking upon the human sensory system, complete ocular examinations were performed in an exceedingly cluster of vernal subjects, before and one hour when smoking. choice of subjects, medical and different safeguards utilised, and details of the protocol are going to be bestowed in an exceedingly later publication.

Visual acuity and intraocular pressure after surgical management of late in-the-bag dislocation of intraocular lenses. A single-centre prospective study

Objectives: to explain index of the minimum angle of resolution (logMAR) best corrected visual sense (BCVA) and pressure (IOP) once surgical management currently in-the-bag dislocation of the lense.

Subjects/methods: during a single-centre prospective study, a hundred sixty five consecutive cases having surgical correction for late in-the-bag-dislocation of intraocular lenses were analysed. annual follow-up knowledge of BCVA, IOP and a specially created composite variable selected “IOP issue” that thought-about IOP ≥ 23 mmHg, in progress pressure reducing treatment and former pressure reducing surgery were compared with baseline values. supplying regression was wont to investigate factors with a attainable influence on the results. [4]

Is There a Causal Relationship between Myopia and Intraocular Pressure

Aims: to see if there’s causative association between shortsightedness and pressure at the University of Port Harcourt Teaching Hospital (UPTH), Nigeria.

Study Design: A case management study.

Place and period of Study: The study was allotted at the University of Port Harcourt Teaching Hospital (UPTH) between Gregorian calendar month, 2012 and will, 2013.

Methodology: Eighty consecutive patients of myopes (group A) and emmetropes (group B) were sampled in 2 teams. A was subgrouped into low shortsightedness. [5]
