ConclusionDespite the generally maintained individual visual capacity in the series, significant correlation could be demonstrated between SFCT and (i) axial elongation and (ii) recorded VA, with a negative and a positive sign, respectively. Overall, the visual prognosis was relatively benign, in particular when compared with the selected high myopia hospital series that predominate in the ophthalmic literature.
Conclusions: The results of our study point to insufficiency of accommodation contributing to the pathogenesis of myopia. PMID: 29348929 [PubMed]
Abstract The incidence of rhegmatogenous retinal detachment in the European population is approximately 10 cases per 100,000 inhabitants per year and reaches a peak in the 6th and 7th decades of life, mostly in atemporal association with posterior vitreous body detachment. Known risk factors include myopia and higher axial length of the eye, male gender, previous trauma and vitreoretinal degeneration or dystrophy. In recent years, an increase in the risk of rhegmatogenous retinal detachment following cataract surgery was also found, especially after capsule rupture and vitreous body loss. In contras...

AbstractPurposeTo compare MMC 0.002% efficacy in preventing haze after PRK in relation to MMC 0.02%.Patients and methods We conducted a prospective study with patients with myopia or myopic astigmatism undergoing PRK in the same conditions. After PRK, MMC was applied for 30 s in a concentration of 0.02% on the right eye (group 1) and 0.002% on the left eye (group 2). Age, gender, spherical equivalent and haze intensity (1, 3, 6 and 12 months postoperatively) were assessed. Haze was quantified at biomicroscopy (0–4 +).P
CONCLUSIONS: It is important to perform vision screening of preschoolers. Early detection of abnormalities in refractive errors could help to minimize the effect of visual impairment.
Conclusions: Varying degrees of myopia did not affect macular vascular density in young healthy adults. In addition, superficial macular vascular density, as an independent factor, was positively correlated with mGCC thickness. PMID: 29318037 [PubMed]
Keratoconus is a progressive corneal disease in which thinning of the corneal stroma causes the cornea to develop a cone-shaped ectasia, which leads to progressive myopia, irregular astigmatism, and often loss of visual acuity.1,2 Therefore, correctly measuring refractive errors is of paramount importance to assess visual performance, disease progression, and the prescription of visual aids in keratoconus. Several methods to measure refractive errors are currently widely used. A manifest refraction is still considered the gold standard to prescribe spectacles.3,4 This subjective technique was
LASIK has been shown to be a safe, effective, and predictable procedure to correct different degrees of myopia, hyperopia, and astigmatism.1,2 However, when compared with myopic corrections, predictability for comparable hyperopic refractive errors is much poorer.3 Thus, published studies indicate a good predictability for low to moderate hyperopic corrections,2 –5 up to +4.00 diopters (D) in most series, but less satisfactory results are reported in the correction of higher degrees of hyperopia.6 Although femtosecond laser –assisted LASIK (FS-LASIK) seems to achieve better refractive outcomes
