Estimation of fibrinogen in the absence of other evaluated causes of blood dyscrasias would help with prompt diagnosis and successful management.

The development of choroidal metastases from a contralateral choroidal melanoma is of ophthalmic interest and seems to be unique.

Purpose: To report two cases that developed neovascuarization of iris, secondary to anterior segment ischemia following vitreoretinal surgery with encirclage. Methods: Retrospective chart review.Patients: Two patients of age 64 and 67 years, who had successful vitreoretinal surgery with encirclage for rhegmatogenous retinal detachment, presented few months later with NVI and features of anterior segment ischemia. Carotid evaluation revealed 50 to 60% carotid obstruction in both patients. Encircling band was sectioned in both the patients.Results: Partial regression of NVI with reversal of symptoms occurred in one patient while ocular ischemia could not be reversed in the other.Conclusion: Carotid insufficiency should be suspected in elderly patients when anterior segment ischemia develops following placement of encircling buckle.
