3, 4, 5 However, in more recent years, there have been reports of acquired forms of keratoglobus. Keratoglobus is primarily considered a congenital disorder present since birth. This article reviews the aetiological factors, differential diagnosis, histopathology, and management options of keratoglobus. In the absence of a definitive standard procedure for management of this disorder, various surgical procedures have been attempted in order to overcome the difficulties. Conservative and surgical management for visual rehabilitation and improved tectonic stability have been described, but remains challenging. Clinical presentation is characterised by progressive diminution resulting from irregular corneal topography with increased corneal fragility due to extreme thinning. However, the exact genetics and pathogenesis are still unclear. Similarities have been found with other noninflammatory thinning disorders like keratoconus that has given rise to hypotheses about the aetiopathogenesis. Both congenital and acquired forms have been shown to occur, and may be associated with various other ocular and systemic syndromes including the connective tissue disorders. It was first described as a separate clinical entity by Verrey in 1947.

Having an advanced corneal topographer and several keratoconus contact lens trial sets available in the office are a positive sign.Keratoglobus is a rare noninflammatory corneal thinning disorder characterised by generalised thinning and globular protrusion of the cornea. Contact lens fitters should be selected on the basis of experience andĬommitment to aiding keratoconus patients. Improperly fit contact lenses can cause extensive damage to the cornea and can ultimately lead to a corneal transplant. As the condition advances, specialized rigid and scleral Custom soft toric contact lenses will often provideĪdequate performance and safety. In the early stages, the central cornea is regular although highly astigmatic. We do our best to keep it simple, but our primary focus will always be on you vision and the health of your eyes.įitting patients with PMD can be especially challenging. For some patients it is a continuing process whichīegins all over again as the condition progresses. In rare cases the process can take many months. You can expect several return visits to fine-tune the fit and prescription. Fitting contact lenses on a keratoconic cornea is delicateĪnd time-consuming. The key to a successful contact lens fitting isn't as much the lens as it is the skill and experience of the contact lens fitter. Scleral lenses have rapidly become a preferred choice for many patients. Some of the newest Zen scleral lenses fitted using ultraprecise optical coherence tomography can provide exceptional comfort and outstanding vision for keratoconus Originally introduced by New Zealand Optometrist, Dr. Keratoconus and pellucid marginal degeneration. The Rose-K is an example of an exceptional and flexible corneal lens design There are numerous contact lens designs used to treat In more advanced keratoconus, rigid gas permeable corneal or scleral contact lenses are usually the best choice for visual rehabilitation. Will often provide acceptable vision and comfort. As the disorder progresses and the corneaīecomes increasingly distorted, specially designed soft lenses ( KeraSoft IC and NovaKone), hybrid rigid-soft ( SynergEyes) lenses In the mildest form of keratoconus, eyeglasses or soft contact lenses often provide adequate vision. We are great believers in conservative treatment.
