Corneal neovascularization, also called Corneal Hypoxia, is a corneal condition where lack of oxygen and stress make irregular veins develop in the typically clear, translucent cornea.
Causes of Corneal Hypoxia
The main reason of corneal hypoxia is absence of oxygen to the cornea. Long-term utilization of contact lenses is a principal factor, however contamination from lenses or from the solution itself, injury or infection, chemical burns, or lens dirt buildup can likewise be a reason.
At the point when contact lenses or some other condition meddles with the flow of oxygen to the cornea, the eye reacts by developing additional veins to help supply oxygen and nutrients to the oxygen-drained tissues. The longer you wear your lenses (over 10 hours every day), the higher the danger of corneal hypoxia and the risk of having corneal neovascularization. At the point when veins stretch out past 2mm from the edge of the cornea, the condition should be dealt with, or permanent intolerance to contact lenses or vision loss can happen.
Corneal hypoxia may likewise be caused by contaminations, injury to the eye, substance burns, immune disorders, and other eye conditions, for example, uveitis, glaucoma and pthisis bulbi.
Symptoms of Corneal Hypoxia
Effectively engorged veins can be found in the white of the eye. Different manifestations of symptoms include the following:
- Redness around the cornea
- Light sensitivity
- Decreased vision or blurring when wearing contact lenses
- Intolerance to contact lens after wearing them for a short time
How do you cope with corneal hypoxia?
Treatment of corneal hypoxia relies upon the seriousness of the condition and the reason behind it. Corticosteroids might be recommended to lessen vascularization. Surgical choices incorporate laser photocoagulation. Lessening or transitory discontinuance of contact lens wear time might be important to enable the tissues to recuperate. You may also opt for an anti-inflammatory treatment like NORFLO. NORFLO’s complex of Curcumin-Phospholipid might help reduce the eye irritation brought on by extensive contact lens use.
A contact lens refit with an oxygen-porous or high oxygen transmissible lens is an alternative that works for some individuals. Once the condition has recuperated, contact lens wearers should give careful consideration to sufficient corneal lubrication.
