Hair may be seen in these fatty tumors as well. Tissue sources include a pericardial graft or amniotic membrane transplantation.
The main limitation of our trial is the small number of cases that forecloses adequate statistical reasoning from our results. Other techniques include corneal-limbal scleral donor graft transplantation and surgical resection followed by reconstructive sutureless multilayered amniotic membrane transplantation.

Mitomycin C as an antitumor antibiotic was first isolated from Streptomyces caespitosus in Anatomically, epibulbar dermoids have been classified into three grades. Fibrin glue-assisted augmented amniotic membrane transplantation for the treatment of large noninfectious corneal perforations. Gorlin RJ, et al. Then the complete lamellar en bloc excision of the corneal and scleral parts of the dermoid was performed including the removal of the entire adjacent conjunctiva.
One of these patients also had a central opacification of the cornea. Eur J Med Genet.

The appropriate time of intervention and the best surgical technique for removal of the pediatric limbal dermoids are subject to discussion. Llmbal et al 5 reviewed the records of 12 patients with solid ocular tumors between andreporting that six lesions could be easily shaved off the cornea and adjacent sclera to improve the appearance of the eye.
Mean visual acuity was 0. Simple and direct excision of such lesions will inevitably result in restrictive strabismus and diplopia. Opacification of part of the graft was seen in Systemic treatment may be indicated for cardiac, renal, or CNS malformations.
One of these eyes was initially treated with bare-sclera excision; the other three eyes had undergone transplantation of amniotic membrane. Table 2 Guarded recommendations for surgical removal of ocular dermoids. Journal Derjoid Eye Lond v. Genetics and inheritance Rermoid pattern of inheritance is quite variable in epibulbar choristomas.
For grade III limbal dermoids, complete anterior segment reconstruction must be anticipated. They reported all but 16 eyes improved cosmetically. No hemivertebra nor butterfly vertebra were found on complete spine films. The group concluded multilayered amniotic membrane transplantation may be effective for the treatment of deep ulceration of the cornea and sclera. At first, the border of the limbal dermoid was marked using a trepan linbal a diamond blade. All patients had been treated consecutively in the past 9 years.
Amniotic membrane transplantation was carried out in four eyes. Limabl this, surgical removal of the limbal dermoid on the left side can be postponed indefinately.
