History
A complete systemic medical history and a review of systems are imperative in these patients, including questions regarding the presence of weight loss, malaise, muscle pain, or weakness, and symptoms involving the neurologic, respiratory, and renal systems.
Physical
- Keratitis sicca is quite common with these patients. Superficial punctate keratitis, chemosis, recurrent episcleritis, and scleritis also are common findings.
- In the case of SLE, retinal vasculitis is evident on fluorescein angiography, with intraretinal hemorrhages and cotton-wool spots. Of patients, 95% develop arthralgia and articular findings, and 70-80% of patients develop skin lesions at some point. The butterfly rash across the nose and cheek occurs in about 30% of patients with SLE.
- Mooren ulcer begins as a gray-white infiltrate in the peripheral cornea followed by epithelial breakdown and stromal melting. Eventually, it develops into a chronic, painful peripheral corneal ulcer that progresses circumferentially and centrally, creating an overhanging edge at its central border. The adjacent conjunctiva and sclera usually are inflamed and hyperemic.
- Wegener granulomatosis is characterized by nasal or oral inflammation, necrotizing and granulomatous inflammation of the vessels of the upper and lower respiratory tract, glomerulonephritis, and other organ involvement with small vessel inflammation.
Causes
All the underlying systemic conditions leading to these types of corneal ulcers are likely to have an autoimmune etiology that is linked to genetic susceptibility.
