Abstract
Purpose
To describe the outcomes of five Salzmann's Nodular Degeneration (SND) cases treated with a combination of alcohol delamination, superficial keratectomy and amniotic membrane patch with fibrin glue.
Methods
Five patients affected by SND with significant discomfort and decreased visual acuity were evaluated with refraction, best corrected visual acuity, Break-up time test, corneal topography, Anterior Segment of Optical Coherence Tomography and images of anterior segment with a full slit lamp examination. All the patients underwent alcohol delamination of the corneal epithelium followed by superficial keratectomy to remove the subepithelial nodules. A patch of amniotic membrane was applied to all of them with a ring shape and a banana shape in two patients due to the location of the disease. A bandage contact lens was inserted. The patch was kept in place for 14 days. Another bandage contact lens was inserted for 21 days until the corneal epithelium had completely healed.
Results
The surgical procedure was successful in removing the nodules in all patients. Vision was restored in all cases with a significant regularization of the corneal surface and reduction of ocular discomfort. After a 12-month follow-up, none of the patients showed recurrence of the disease.
Conclusions
Combining alcohol delamination with superficial keratectomy and amniotic membrane patch with fibrin glue is an effective procedure for the management of SND to regularize the corneal surface and avoid the recurrence of subsequent nodules. This report is the first description of the outcomes of SND cases treated with a combination of the aforementioned techniques.
