Blepharitis

Considerations with Lasik, All-Laser Lasik, PRK, LASEK, Epi-Lasik, CK, RLE, and P-IOL

Blepharitis is a reddening of the eye lids caused by inflammation or infection that must be managed before Lasik laser eye surgery.

 

Blepharitis is a contraindication for most cornea-based refractive surgery techniques, including conventional or wavefront Lasik, All-Laser Lasik, PRK, LASEK, and Epi-Lasik, unless the blepharitis is very mild and/or is fully under control. Blepharitis is a consideration for CK, P-IOL, and RLE, but does not seem to be as critical.

Blepharitis is an inflammation of the eyelids. It is a very common condition that can be associated with a low grade bacterial infection (staphylococcal blepharitis) or a generalized skin condition (seborrheic blepharitis). Blepharitis is seen most commonly in adults.

Factors believed to contribute to blepharitis include abnormalities in oil gland function and an alteration in bacterial colonies that normally live on the skin. Blepharitis is not contagious and cannot be passed from one person to another.

People with blepharitis will have red eyelid margins and persistent ocular irritation, however there are other ocular problems that will have similar symptoms. An ophthalmologist can help definitively diagnose this condition by careful examination of the eyelid margins. In some instances, dry eye symptoms and underlying skin conditions can be associated with blepharitis.

The inflammation around the eyelids characteristic of blepharitis can be improved by increased lid hygiene. Gently scrubbing the eyelid margins with baby shampoo diluted with water can decrease the amount of flaking skin and oil in the area. A cotton tipped applicator or a washcloth wrapped around the index finger can be used to apply the shampoo.

Warm compresses applied to the lids for several minutes a day can also be helpful. In some select cases, your ophthalmologist may also choose to prescribe an antibiotic ointment or drop. Restasis is a cyclosporine eye drop that has been shown to be very helpful for blepharitis.

Blepharitis is a chronic condition that often requires long-term treatment in order to prevent exacerbations.

If you are ready to choose a doctor to be evaluated for conventional or custom wavefront Lasik, All-Laser Lasik, PRK, LASEK, Epi-Lasik, NearVision CK, RLE, or any refractive surgery procedure, we highly recommend you consider a doctor who has been evaluated and certified by the USAEyes nonprofit organization.

Branched-chain fatty acids, increased in tears of blepharitis patients, are not toxic for conjunctival cells.

Br J Ophthalmol. 2009 Jun 10;

Authors: Joffre C, Souchier M, Leclere L, Buteau B, Grégoire S, Lizard G, Montange T, Acar N, Bron AM, Creuzot-Garcher CP, Diebold Y, Bretillon L

PURPOSE: The composition of the meibum of blepharitis patients is characterised by increased levels of branched-chain fatty acids (BCFAs) that return to normal values in patients treated with cyclins and lid hygiene. The aim of this study was to determine if BCFAs had toxic effects on conjunctival cells related to the disease. METHODS: Chang and IOBA-NHC conjunctival human cells were treated with BCFAs (isoC16, and isoC20) or palmitic acid as a control for 4 h or 24 h at 50 microM or 100 microM. Morphological and functional changes were investigated by measuring mitochondrial dehydrogenase activity, cell permeability, mitochondrial depolarisation, chromatin condensation, IL-1beta and reactive oxygen species production. RESULTS: None of the fatty acids modified the parameters of cytotoxicity in conjunctival cells in Chang or IOBA-NHC cell lines. Only the mitochondrial dehydrogenase activity was significantly decreased in relation to the isoC20 concentration increase. CONCLUSIONS: The increase in BCFAs in the tears of blepharitis patients does not consistently participate in the conjunctival cell changes throughout the course of the disease. Instead, it is likely an adaptive response of the ocular surface to the lack of tears, possibly increasing meibum fluidity, thus enhancing lacrimal film stability.
