| Abstract | ||
| Background: phacoemulsification continues to be one of the most popular surgical procedures for cataract extraction in the ophthalmologic practice. Optical Coherence Tomography (OCT) is a noninvasive and noncontact diagnostic tool with high resolution to assess macular changes. Aim of the study: evaluate changes in macular thickness, micro vascular changes and peri papillary NFL thickness that occur after uncomplicated phacoemulsification surgery in eyes with and without DR in diabetic patients and in a control group. Methods: This study was designed as Prospective, non-randomized study controlled clinical trial. included 100 eyes. Included Diabetic and non-diabetic patients were scheduled for phacoemulsification surgery with intraocular lens (IOL) implantation included divided into four groups: control group, non-diabetic, diabetic with no DR, diabetic with mild -moderate NPDR, diabetic with severe NPDR. The central retinal (foveal) thickness microvascular changes & peripapillary NFL thickness of all patients measured with OCT one week and 1, 3, and 6 months after surgery. A fundus examination with full pupil dilation performed during each scheduled examination. Results: There was non-significant difference in central macular thickness CMT, RNFL after one month there was a significant difference between groups while after 3 & 6 months the difference was highly significant. Regarding visual acuity evaluation there was significant difference between different groups at preoperative and after 1week in the BCVA, also there was moderate significant difference between different groups after 1month, 3months & 6months. Conclusion: cataract phacoemulsification cause increase in CMT, RNFL thickness and SCP values in diabetic with different severities of retinopathy. | ||
