H18.793
Other corneal deformities, bilateral
Clinical Classification Guidelines
Medical Intelligence & Overview
Bilateral corneal deformities involve abnormal shapes or structures affecting both corneas of the eyes. The cornea is the clear, dome-shaped front surface of the eye that plays a vital role in focusing light onto the retina. When deformities occur, they can impact vision, causing blurriness, distortion, or other visual disturbances. Recognizing and understanding these conditions is essential for appropriate management and maintaining eye health.
Causes & Symptoms
Clinical Causes: Genetic factors that influence corneal shape and structure Keratoconus, a common progressive thinning and cone-shaped deformation of the cornea Corneal dystrophies, inherited disorders leading to abnormal corneal tissue build-up Previous eye injuries or infections that weaken or scar the cornea Systemic diseases, such as keratoglobus or pellucid marginal degeneration Overuse of contact lenses leading to corneal stress or deformation Certain autoimmune conditions that affect corneal integrity
Key Symptoms: Blurred or distorted vision Light sensitivity (photophobia) Glare or halos around lights, especially at night Feeling of a foreign body in the eye Sharp or fluctuating vision changes Sometimes, visual acuity may remain normal in early stages
Diagnostic & Treatment
Diagnosis Path: Visual acuity tests to assess clarity of vision Slit-lamp biomicroscopy for detailed examination of corneal shape and surface Corneal topography or tomography to produce detailed maps of corneal curvature and shape Pachymetry measurements to determine corneal thickness Optical coherence tomography (OCT) may be utilized for detailed imaging Assessment of overall eye health and ruling out other ocular conditions
Treatment Protocols: Corrective lenses such as glasses or custom contact lenses designed for irregular corneas Rigid gas-permeable contact lenses that can reshape the cornea temporarily and improve vision Surgical interventions like corneal cross-linking to strengthen the corneal tissue and prevent progression At times, specialized procedures such as intracorneal ring segments are used to flatten or reshape the cornea In advanced cases, corneal transplantation may be considered Regular monitoring and follow-up care to assess disease progression and adjust treatment as needed
