Abstract Details

Purpose:

The evaluation of pterygiums by the Spectral domain anterior segment optical coherence tomography in order to diminish recurrences.

Setting:

the prospective study was carried out in the ophthalmology department of  Avicenne military hospital of Marrakech during a period of 6 months on 60 eyes including primary and recurrent pterygiums.

Methods:

We have conducted horizontal and vertical scans of primary and recurrent pterygiums by the anterior segment OCT and analyzed the anatomical relationship between pterygiums and the tissues of the cornea and the conjunctiva.

Results:

In primary pterygiums, the horizontal OCT scans have revealed  a mass of tissue  separating the corneal epithelium from the Bowman membrane. They also showed  an extension of the pterygium tissue beyond the corneal edge of the clinically visible pterygium mass. Else way, vertical scans revealed the destruction of the Bowman membrane and the invasion of superficial corneal stroma. In recurrents pterygiums, the epithelial invasion was found to be more advanced and creeping the Bowman membrane than the primary pterygiums.

Conclusions:

The use of the anterior segment OCT provided us with high-resolution images of the pterygiums. Hence, this can help reduce the rate of recurrences by providing real-time images of the lesion ensuring its total excision.
