Symblepharon describes varying degrees of adhesion between adjacent conjunctival surfaces (including palpebral and/or third eyelid surfaces) and/or the cornea. Clinically, varying degrees of fibrosing and/or pigmantary areas of tissue are noted to extend across palpebral and/or corneal surfaces. Conjunctivitis, chemosis, fibrosis and or ocular discharge may additionally be present. Significant narrowing of the palpebral fissure and/or occlusion of the corneal surface may also result. Symblepharon results from loss of epithelial continuity, most commonly arising secondary to feline herpesviral disease but potentially arising secondary to any severe feline or canine conjunctival inflammation.
