We describe a case of a 47-year-old woman who underwent bilateral laser in situ keratomileusis (LASIK) for the correction of myopia and astigmatism. Two months later a residual refractive error was present in both eyes. LASIK retreatment was decided and performed the following day. Twenty-four hours after the procedure, the patient reported myodesopsia in both eyes. Funduscopic examination revealed a complete bilateral posterior vitreous detachment confirmed by kinetic ultrasound. Visual disturbance in both eyes continued to be present after 10 months of follow-up. Sudden changes in intraocular pressure related to suction ring use might be the cause of posterior vitreous detachment in this patient.

Proliferative vitreoretinopathy (PVR) is a major cause of rhegmatogenous retinal detachment repair failure. Despite many attempts to find therapeutics for PVR, no pharmacotherapy has been proven effective. Steroids, as the epitome, show uncertain clinical effectiveness, which lacks an explanation and hints at unappreciated mechanisms of PVR.

Diabetic retinopathy is one of the most severe forms of retinopathy and a leading cause of blindness all over the world. Of a greater concern is proliferative diabetic retinopathy which leads to vitreous haemorrhage and tractional retinal detachment in such cases. A majority of these cases require a surgical intervention to improve vision and prevent further vision loss.

To evaluate whether infrared video imaging can supplement traditional examination and imaging methods to identify and quantify symptomatic vitreous opacities. A prospective nonrandomized nonmasked series was performed that included eyes of consecutive patients with a primary complaint of symptomatic vitreous opacities. A macular vitreous opacity score (0-4) was developed to grade the size of the opacities in relation to the macula after refixation of up, down, left, and right saccades.
