Further Research needed to explore the link between Posterior keratoconus and Ocular coloboma

keratoconus journal
Posterior keratoconus is a rare corneal disorder that results in non-inflammatory thinning of the cornea, leading to cone-like protuberance in the posterior cornea. Ocular coloboma is malformation due to faulty closure of the embryonic fissure, where the entire ocular structure may affect iris, ciliary body, choroid, optic nerve or all of the above. Posterior keratoconus may lead to vision loss over a period of time. A rare case of both Posterior keratoconus along with Ocular coloboma was presented here. The study predict genetic linkage as one of the reasons and suggest further studies to explore the link between Posterior keratoconus and the Ocular coloboma.

Keratoconus Management: Role of GP Contact Lenses

Keratoconus is a corneal disorder progressive characterized by thinning and steepening of the central and paracentral cornea, which leads to protrusion. The exact cause of the disease remains to be fully elucidated although its etiology probably is multi factorial with a genetic predisposition to keratoconus influenced by external environmental factors (eye rubbing and atopy) with different systemic involvement. In the early stages, keratoconus can be managed with spectacles or contact lenses (CL), but when keratoconus progresses, other surgical techniques are often required.

For example, anterior lamellar (dDALK) or penetrating keratoplasty (PK) permit than 3 of 4 patients achieve best-corrected visual acuity of 20/40 or better. Intra corneal ring segment(ICRS) are proposed to increase corneal stability and decrease the astigmatism a symmetry normalizing the corneal contour with slight improvement of patients’visual acuity. Corneal collagen cross-linking (CXL) is a common technique proposed to reduce disease progression with a light improvement of visual acuity (1 to 2 Snellen lines).
