**6. Complications**

Corneal dryness, abrasion and ulceration are very common in patients with leprosy due to the secretory irregularity and corneal insensitivity. A careful eye examination should be performed in every leprosy patient to prevent serious complications that can result in blindness.

Depending on the perforation and collapse of the nasal septum, saddle nose and rhinitis-like findings can be observed. Snoring due to nodule occurrence in vocal cords and larynx involvement, and gynecomastia, impotence and infertility as a result of decrease in blood testosterone level due to testicular involvement in male patients may be seen [61].

Venous insufficiency due to endothelial involvement of the valves of deep venous vessels may lead to stasis dermatitis and venous ulcers.

In the advanced disease phase, multiorgan involvement (liver, spleen, peripheral lymph nodes, bone marrow) can be observed.
