HYPERTENSIVE RETINOPATHY

Changes of the retina in the arterial hypertension are the indicator of the state of blood vessels in other organs; therefore, examination of the eye background should be an integral part of treatment and monitoring of hypertensive patients. Hypertensive retinal vascular disease is graded in four levels.   I degree This degree reflects the initial […]

CENTRAL SEROUS RETINOPATHY

Central serous retinopathy is a disorder that affects the central part of the retina or yellow spot (macula). The disease usually affects younger people and people of middle age (25-50 years), especially men.                                        The initial stage                                            […]

DIABETIC RETINOPATHY

Diabetes mellitus (DM), i.e. diabetes, in the world today has a 2 – 3% of the population. Today we are talking about two forms of DM:   Insulin-dependent (type I) usually aged 10-20 years. Insulin independent (type II) usually aged 50-70 years. Diabetic retinopathy is a retinal vascular complication of diabetes and it is the […]

THE RETINA

RETINOSCHISIS (SPLITTING OF THE RETINA)  Retinoschisis is an eye disease characterized by abnormal splitting of the neurosensitive layers of the retina, usually in the outer plexiform layer, resulting in loss of vision or of the corresponding visual field in some rare formats. More common forms are usually asymptomatic.     Types: Degenerative retinoschisis This type […]

DYSGENESES OF THE IRIS AND THE CHOROID

DYSGENESES OF THE IRIS AND THE CHOROID With aniridia the iris is undeveloped – there is only a narrow atrophic ring of the iris tissue, and the pupil is huge. Corectopia is an eccentric position of the pupil, which is, in addition, deformed. It can be congenital, but today it is mostly a result of […]

STAFILOM OF THE SCLERA

STAFILOM OF THE SCLERA

It is a degenerative change – protrusion of the locally thinned sclera     Causes: Thinning is caused by inflammation, poorly repaired perforated injury, high myopia or very high intraocular pressure. Through this thinned sclera, uvea shines darkly. Treatment:   At the risk of perforation, the thinned spot is reinforced by implants (fascia; dead donor […]

DYSTROPHIES OF THE CORNEA

These are hereditary multiple corneal turbidities. They are called by the appearance of turbidity (annular, macular, granular, mesh, crystal, drop), or according to the authors (Meesman, Cogan, Reis Buckler, Groenouw, Biber, Schnyder, Fuchs, etc.).                       Treatment: Turbidity, which can significantly reduce the visual acuity, requires corneal […]

DYSGENESES OF THE CORNEA

These are congenital disorders of the corneal anatomy: Microcornea – corneal diameter less than 10 mm Cornea of the plan – the cornea is curved at the same radius as the sclera Megalocornea – corneal diameter greater than 12 mm in a newborn Keratoglobus – cornea large, thinned, mostly on the middle periphery, and more […]

CORNEAL EROSION

CORNEAL EROSION

Since the corneal epithelium and its basement membrane are of different embryological origin, the connection between them is weak. Therefore even a small trauma can cause erosion, i.e. the separation of epithelium from the surface. Therefore, the erosion of the cornea is most frequent eye trauma. Stripped nerve fibers at the site of erosion are […]

DEGENERATIONS OF THE CORNEA

DEGENERATIONS OF THE CORNEA

Those are acquired diseases which are associated with earlier corneal diseases (inflammation, injury, surgery on the cornea, lagophtalmus), metabolic disorders, atrophy of the eyeball or of unknown causes. Depending on the cause, there are edema, bullae, ulcers, blur, neovascularization, various deposits (amyloid, lipids, lime, etc.).     corneal degeneration in layers Treatment: Whenever possible, the primary […]
