describe the series of events that occur during retinal detachment surgery.
After re-examination with indirect
ophthalmoscopy, while the patient is anesthetized, cryothermy or diathermy is
used to allow the retina to oppose pigment epithelium. Retinal tears are
covered with a scleral buckle, which is sutured into place. A small incision
perforating the scleral-choroidal region drains accumulated subretinal fluid,
allowing the retina to oppose the scleral buckle and close the tear.
