Presence of hyaline ridges or glass menbrane in the anterior chamber of the eye is very rare. These are formed as a result of the abnormal hyperplastic activity of the endothelial cells in certain pathological conditions[1] Perera[2] noticed it in a child following birth injury. These may be found either closely applied to the posterior surface of the cornea or lying in the anterior chamber as curtain, attached to the cornea at one or both ends. We document a case of glass membrane in both the eyes.
Case report | | |
M. C. 25 HM presented with complaints of gradual progressive diminution of vision since childhood more in right eye. There was no history of trauma. On examination, the lids and conjunctiva were found to be normal in both eyes. The corneae were globular, vascularised and hazy. The anterior chamber was deep.
Right eye showed a membrane like structure running across the anterior chamber from 7 to 9 O'clock position to 1 to 3 O'clock position. Only part of iris was visible [Figure - 1] Visual acuity was H. M. Perception and projection vas accurate in all quadrants. Tension was digitally normal.
Left eye showed a similar but less extensive membrane extending from 7 to 9 O'clock position to 3 O'clock position Iris and pupil were only partly visible. Fundus showed no abnormality. Visual acuity was 6/36 Tension was digitally normal.
Discussion | | |
The Descemet's membrane is secreted a, hyaline tissue by the endothelial cell in the fourth month of intra-uterine life. It has the property of regeneration. In some pathological conditions and following trauma the Descemet's membrane gets detached and lies as a ribbon like structure running across the anterior chamber. The original defect is then filled in by the fresh layer (Mc Grand 1968).[1]
Alternatively the endothelial cells may exhibit hyperplastic activity resulting in deposition of excessive amount of hyaline tissue leading to increased corneal thickness.

A case of class membrane in anterior chamber is reported.
