TRANSLUCENCY OF THE SCLERA

Acta Ophthalmologica, 1973
Gross examination with a pencil torch of 319 non‐selected patients disclosed in 117 cases a greyish translucent streak in the sclera along the tendon attachment of one or more of the horizontal eye muscles.The phenomenon was found to rise in frequency with increasing age, having been noticed in only 4 per cent of the patients aged under 60, against in ...
