Operculum and
retinal hole
by Professor Chua Chung
Nen and Dr Adrian Koay
A 52 year-old man
presented with sudden onset right floater. The visual acuity measured 6/9.
Slit-lamp examination showed posterior vitreous detachment and an operculum.
Fundoscopy with a superfield 90D lens revealed a retinal hole with
subretinal haemorrhage at the superotemporal retina. Argon laser was
performed to prevent retinal detachment (150 X 200um X 200mW X0.1sec).
The risk of retinal
detachment is less with retinal hole than retinal tear.
Slit-lamp view of posterior vitreous detachment and operculum.
Relation between the operculum (red arrow) and the retinal hole (blue error)
at the peripheral superotemporal retina through the view of a 90D superfield
lens.
Another view of the above through slit-lamp fundoscopy.
Post-argon laser photocoagulation surrounding
the retinal hole.
