Purpose: To compare the safety and performance clinical outcomes of the 27-gauge (G) two-dimensional cutting vitrectomy probe versus a standard 25-G probe for retinal procedures.
Methods: In this large randomized prospective study, all candidates for epiretinal membrane or macular hole surgery were randomized to the 27-G group or 25-G group. Outcome measures included surgery time, changes in best-corrected distance visual acuity, intraocular pressure, and central macular thickness between baseline and 1-month and 3-month follow-up time points.
Objective: Diabetic retinopathy is associated with progressive retinal capillary activation and proliferation, leading to vision impairment and blindness. Microparticles are submicron membrane vesicles with biological activities, released following cell activation or apoptosis. We tested the hypothesis that proangiogenic microparticles accumulate in vitreous fluid in diabetic retinopathy.

The aim of this prospective study of 62 keratoplasty patients was to assess the incidence of macular edema by using optical coherence tomography (OCT 3; Stratus, Carl Zeiss Meditec, Dublin, CA) and to identify factors associated with edema.
Methods: Sixty-two patients who were all operated on by the same surgeon were examined by OCT 3, 1 and 3 months after corneal graft.
