Rheumatic diseases are frequently associated with eye disorders presenting with a wide range of signs and symptoms. Dry eye syndrome, keratitis, uveitis, scleritis and retinal vasculitis are often diagnosed in patients with rheumatic diseases. It is important not to overlook even subtle signs of ocular involvement as it may result in serious complications. Moreover in some cases ocular manifestation may help in proper diagnosis of systemic condition or indicate necessity of intensified treatment of underlying condition. Appropriate treatment of rheumatic diseases require careful follow up and involvement of various specialists including ophthalmologists as well as patient education.

Introduction: Corneal endothelium is a single layer of cells, which do not regenerate. Damage to the endothelium can take place in the course of certain diseases and after intraocular operations. When the number of endothelial cells decreases, corneal decompensation can occur. Pre- and postoperative measurement of the number of the corneal endothelial cells can help assess the degree of corneal damage during the surgery., Purpose: To compare the effect of various factors, such as: sex, age, corneal incision, intraocular pressure, cataract density, visual acuity and surgeon's experience on corneal endothelial cell loss following uneventful phacoemulsification., Material and Methods: 365 patients (114 men and 251 women aged 19 to 91 years) undergoing phacoemulsification were examined preoperatively and postoperatively at 4 weeks. 68 eyes underwent phacoemulsification through a 1.8 mm microincision and 297 eyes through a standard 2.75 mm incision. Patients were operated on by four surgeons., Results: There was a significant difference in the postoperative endothelial cell loss relative to the degree of cataract hardness (p < 0.001). Endothelial cell loss was significantly higher in patients aged 71 and above than in the remaining age groups. Significant differences in the postoperative endothelial cell loss were observed in relation to the clear corneal incision size (p < 0.01). Preoperative best corrected visual acuity influenced the postoperative endothelial cell loss in a statistically significant way (p < 0.05). Endothelial cell loss was strongly influenced by the surgeon's experience., Conclusions: Surgeon's experience, hardness of cataract, type of corneal incision, age and preoperative visual acuity influenced endothelial cell loss at 4 weeks following uneventful phacoemulsification, however such factors as sex and intraocular pressure showed no statistically significant influence on corneal endothelial cell loss.
