BACKGROUND Stimulus deprivation amblyopia is the principal cause of visual impairment in infants with unilateral congenital cataract. Even if lensectomy is undertaken at an early age, intensive postoperative occlusion of the phakic eye is essential for the development of useful vision in the aphakic eye. Despite this, the optimum method of regulating occlusion therapy is uncertain. METHODS In...

A 35-year-old woman presented to the emergency department of Moorfields Eye Hospital with a 10-day history of pain, reduced vision in her right eye, and headache. She described the visual disturbance as “sparkly lights.” She had undergone bilateral lensectomy at the age of 7 weeks for congenital cataract and was aphakic. Her corrected visual acuity was 6/36 in each eye with +19.0 D sphere corre...

We are taught-though it is impossible to establish on what authority-that the human crystalline lens specifically protects the retina and choroid from thermal damage. To be more precise: if a glass blower has had a lens removed because of a radiation cataract he is advised not to return to his job. It seems, however, that, if his vision can be restored to enable him to resolve all the necessary...

introduction blue light is a part of the spectrum with the highest energy content, which can reach the retina. the damage that it can cause to the retina is called photochemical or blue-light retinal injury. for the retinal injury assessment of the photochemical and aphakic retinal hazards in the wavelength range of 300-700 nm, use of effective spectral radiance limits (w.m-2.sr-1) seems to be ...

PURPOSE A monkey model was used to evaluate intraocular lenses (IOLs) and extended-wear contact lenses (EWCLs) for the optical treatment of infantile aphakia in humans. Specifically, the relative effectiveness of EWCLs used alone and IOLs used in combination with EWCLs in preventing amblyopia was assessed. METHODS A total of 33 rhesus monkeys was studied in this project, 24 assigned to experi...

INTRODUCTION Retinal detachment remains one of the most serious complications of cataract surgery. Treatment of this condition has represented a challenge for vitreoretinal surgeons.Scleral buckle (SB) surgery is one of the treatment options in pseudophakic and aphakic retinal detachment (RD). AIMS To find out the anatomical and visual outcome of SB in pseudophakic and aphakic RD. SUBJECTS ...
