A 65-year-old diabetic and hypertensive male presented with a sudden diminution of vision after sustaining a trivial fingernail injury to his only good-seeing (right) eye. The patient underwent phacotrabeculectomy with posterior chamber intraocular lens (PCIOL) implantation 22 years previously. In his right eye visual acuity at presentation was counting fingers at 1.5 m with an accurate projection of light. Intraocular pressure (IOP) was 4 mmHg. The anterior chamber was uniformly shallow with a peripheral iridocorneal touch. Angle details could not be visualized. The bleb was avascular, thin and cystic with a positive forced Seidel test. Fundus examination showed 360° choroidal detachments. B-scan ultrasound revealed massive choroidals. Revision of dysfunctional filtering bleb by conjunctival advancement with bleb preservation and anterior chamber reformation with healon was performed. Postoperatively, the first day visual acuity improved to 6/36, the anterior chamber was deep, bleb was well covered with conjunctiva, the IOP was 10 mmHg and fundus examination revealed resolving choroidals. At the final follow up at 4 months, the patient did not require medication and visual acuity was 6/12, the bleb was functioning well with an IOP of 14 mmHg. Examination of the fundus revealed a cup-to-disc ratio of 0.5 with moderate non-proliferative diabetic retinopathy changes. The patient has been advised to maintain a strict glycemic control and return for routine follow up after 3 months.
