Relationship Between Intraocular Pressure and Age: A Population-Based Study in Nepal.

Prcis: Intraocular pressure (IOP) decreased with age in a population-based study in Nepal, from a mean of 14.1 mm Hg among those 60-64 years old to 13.0 mm Hg among those 80 years old or older.

Should We Perform Early Cataract Surgery? A Patient Reported Outcome Study.

Purpose: Current guidance states that access to cataract surgery should not be restricted by visual acuity (VA); nevertheless, 6/12 is used as a cut-off criterion in some health institutions. This study aims to determine the benefits of performing cataract surgery in patients with VA of 6/9 or better in both eyes; determine whether these benefits change over time; and compare the benefit observed between early first eye and second eye surgery.

Patients And Methods: Fifty adults with VA at least 6/9 in the worst eye and no ocular comorbidity were recruited.

Agreement amongst consultant ophthalmologists on levels of visual disability required for eligibility for certificate of sight impairment : Sight impairment registration using binocular composite visual fields.

Background: Registration as sight impaired allows access to services important for patients. The rates of sight impairment due to visual field loss are underestimated. Previous work has shown that evaluation of visual field defects in both eyes produces poor agreement among ophthalmologists for categorisation of patients as eligible for sight impairment registration.
