Opacities of the vitreous body can occur as a result of metabolic disorders in diabetes mellitus, hypertension, atherosclerosis, as well as inflammatory diseases of the vascular tract and injuries.
Many systemic diseases in children can be accompanied by congenital cataracts. The vast majority are extremely rare and are of interest to pediatric ophthalmologists.
Late chronic sluggish endophthalmitis develops in case of retention of a low-virulence pathogen in the capsular bag. The onset of the disease varies from 4 weeks to several years (on average 9 months) after surgery and, as a rule, is a consequence of conventional cataract extraction with implantation of a ZK-IOL.
Rupture of the posterior capsule is a fairly serious complication after cataract surgery, as it can be accompanied by loss of the vitreous body, posterior migration of the lens masses and, less commonly, expulsive bleeding.
Complicated cataracts occur as a result of exposure to unfavorable external and internal factors. Complicated cataracts are characterized by the development of opacity under the posterior capsule of the lens and in the peripheral parts of the posterior cortex.
Congenital cataracts develop as a result of intrauterine pathology and are often combined with various developmental defects of both the eye and other organs.
Cataract is a congenital or acquired degenerative clouding of the lens. The main symptom is a gradual painless blurring of vision. Diagnosis is established ophthalmoscopically and by slit lamp examination. Treatment of cataract involves surgical removal of the lens and implantation of an intraocular lens.
Dislocation of the lens is a complete detachment of the lens from the supporting ligament and its displacement into the anterior or posterior chamber of the eye. In this case, a sharp decrease in visual acuity occurs, since a lens with a power of 19.0 diopters has fallen out of the optical system of the eye.
