Keratoconus: diagnosis, prognosis and treatment methods

Understanding Keratoconus

Keratoconus is a progressive congenital or acquired disease of the cornea, characterized by gradual thinning and protrusion of the central part of the cornea. Patients with keratoconus may experience varying degrees of vision distortion, often leading to a decline in quality of life. The diagnosis of keratoconus is made based on symptoms and the results of an ophthalmological examination, which allows for the determination of treatment methods and prognosis for each specific case.

Factors contributing to the development of Keratoconus

Keratoconus is a progressive change in the shape of the cornea caused by the weakening of its collagen fibers. Many factors can contribute to the development of this disease, including genetic predispositions, scarring of the cornea after injury, regular rubbing of the eyes against sharp microobjects, as well as wearing suitable lenses, both soft and rigid gas-permeable. Patients with a family history or with common connective tissue anomalies also have an increased risk of developing keratoconus. This complex condition requires further research for a better understanding of its causes and influencing factors on development.

Research on this topic is ongoing, and there is currently no definite consensus regarding a single cause of keratoconus. It is important to consider the numerous potential factors that may influence the development of the disease, including genetic and external factors affecting the cornea. While the mechanisms of keratoconus onset are not entirely understood, understanding these factors is crucial for effective intervention aimed at slowing or altering the course of the disease.

  • Genetic predisposition: Hereditary factors may contribute to the development of keratoconus, especially if family members also have this condition.
  • Corneal trauma: Scarring of the cornea after injury or surgical intervention may increase the risk of developing keratoconus.
  • Rubbing eyes with microobjects: Constant rubbing of the eyes against sharp objects, such as microobjects, can weaken the cornea.
  • Wearing unsuitable lenses: Wearing inappropriate contact lenses, including soft and hard gas-permeable lenses, may increase the risk of developing keratoconus.
  • Connective tissue disorders: Patients with general connective tissue disorders may also have an increased risk of developing keratoconus due to a weakened corneal structure.

Recognition of Keratoconus Symptoms

The diagnosis of keratoconus is based on characteristic symptoms and clinical signs. Patients often complain of a gradual deterioration of vision, despite correction with glasses or contact lenses. One of the characteristic symptoms is the distortion of visual images in the form of heaviness, stretching, or distortion, especially when looking at bright light or point sources of light.

In keratoconus, sensitivity to light, unpleasant sensations, and blocked green thin circles when looking at a light source are also often noted, as well as eye fatigue at the end of the day. These symptoms can be harbingers of the disease and require timely consultation with a specialist for further diagnosis and treatment.

  • Gradual deterioration of vision: Patients may experience difficulty seeing clearly, despite using glasses or contact lenses.
  • Distortion of visual images: Characterized by heaviness, stretching, or distortion of images, especially in bright light or when there are point light sources present.
  • Photophobia: Patients may feel discomfort and unpleasant sensations when looking directly at a light source.
  • Appearance of obscured green thin circles: May be observed when looking at a light source, indicating changes in the shape of the cornea.
  • Eye fatigue: Patients may complain of eye strain by the end of the day, which may also be one of the signs of possible keratoconus.

Expert recommendations for the treatment of keratoconus

Expert recommendations for the treatment of keratoconus are usually based on the stage of the disease and individual patient characteristics. In the early stages of keratoconus, it is generally recommended to monitor the condition of the cornea and to correct vision with glasses or contact lenses. However, in cases of progressive keratoconus or significant vision deterioration, surgical intervention may be necessary.

Among the methods of surgical treatment for keratoconus, experts highlight corneal transplantation and the introduction of keratoconus-stabilizing inserts. Each method has its own specifics and is applicable depending on the clinical picture and patient needs. Expert opinion plays a key role in choosing the optimal treatment, as it takes into account not only research recommendations but also the practical experience of specialists in the field of keratoconus.

Approaches to the diagnosis of keratoconus

The diagnosis of keratoconus includes several methods based on clinical signs and instrumental examinations of the eye. One of the primary methods is the examination of the cornea using a special instrument – a keratometer. This device allows for the measurement of the steepness and curvature of the corneal surface, which is an important indicator in the diagnosis of keratoconus. Keratoconus can also be detected using corneal topography, which allows for the assessment of its shape and structure.

Modern diagnostic methods for keratoconus include optical coherence tomography and pentacam scanners, which enable more accurate evaluation of changes in the corneal structure and its thickness. In addition, a significant tool for diagnosing keratoconus is ultrasonic echobiomicroscopy, which allows for the assessment of the internal structures of the eye and the determination of the degree of corneal involvement in the disease. All of these methods play an important role in forming an accurate diagnosis of keratoconus and determining the further treatment strategy.

  • Corneal examination using a keratometer: this method allows measuring the curvature and contour of the corneal surface, which is important in diagnosing keratoconus.
  • Corneal topography: topographic examination provides a detailed assessment of the shape and structure of the cornea, which helps to identify changes characteristic of keratoconus.
  • Optical coherence tomography: this method allows obtaining high-quality images of the eye structures and assists in the diagnosis of keratoconus.
  • Pentacam scanners: the use of pentacam scanners allows for more accurate assessment of the corneal structure and changes that may indicate keratoconus.
  • Anterior segment echobiomicroscopy: this method helps assess the internal structures of the eye and can be useful in detecting keratoconus and evaluating its characteristics.

Methods of treating keratoconus

The treatment of keratoconus directly depends on the degree of disease progression. In the initial stages, methods of optical correction, such as glasses or contact lenses, may be used to improve visual quality and assist the patient in daily tasks. In more advanced cases, when the deterioration of corneal structure becomes more evident, surgical intervention may be necessary. Corneal transplant or modern surgical correction methods, such as collagen cross-linking or corneal curvature implantation, may also be considered as treatment options if needed.

It is important to individualize the approach to treating keratoconus, taking into account the characteristics of each specific case and the level of disease progression. Early detection and timely treatment can help improve the prognosis and quality of life for patients with keratoconus. Close interaction between the specialist and the patient helps to determine the optimal treatment strategy and ensure the best outcomes.

  • Optical vision correction: Patients with keratoconus may be prescribed glasses or contact lenses for everyday use to improve vision.
  • Corneal collagen crosslinking: This procedural method involves the use of special solutions and ultraviolet radiation to strengthen the collagen fibers of the cornea, which may help slow the progression of keratoconus.
  • Corneal curvature implantation: A surgical procedure aimed at changing the shape of the cornea to improve vision and correct distortions characteristic of keratoconus.
  • Corneal transplantation: In cases of significant corneal damage due to keratoconus, surgical intervention may be required to replace the cornea with donor tissue.
  • Monitoring and regular examination: Patients with keratoconus should undergo regular examinations by an ophthalmologist to monitor the condition of the cornea and the effectiveness of the chosen treatment method.

Prevention measures for keratoconus

Preventing keratoconus is important for slowing the progression of the disease. Avoiding eye trauma and regularly conducting examinations with an ophthalmologist contribute to the early detection of the initial stages of keratoconus.
