Abstract
This is a prospective, interventional study that included 88 eyes of 88 patients attending outpatient clinic of Mansoura Ophthalmic center. They presented with senile immature cataract during the period between May, 2016 and May, 2019. This study aimed to assess the ability of optical coherence tomography (OCT) to diagnose macular changes pre and post cataract surgery and to identify changes in central foveal thickness (CFT). All cases were subjected to complete history taking, thorough ophthalmic examination, and OCT scanning. After performing cataract surgery, anti inflammatory eye drops were used to treat eye inflammation. At follow up, all cases were evaluated by slit lamp examination, OCT scanning, fundus examination with slit lamp biomicroscopy with the+ 90D lens, as well as intraocular tension measurement by applanation tonometry. In this study, The mean age of the included patients was 62.03 years while female sex was more common than males (54.5% vs. 45.5%). Regarding medical history, about 52.2% (46 eyes) of patients had irrelevant medical history. While 12 eyes (13.6%) of patients had diabetes only,other 10 eyes (11.4%) of patients had hypertension. Additionally, 20 eyes (22.7%) of patients had both hypertension and diabetes. Normal fundus was encountered in 76.14% of eyes (67 eyes) while age related macular degeneration(ARMD) ” hard drusen” was identified in 11eyes (12.5%). Additionally, epiretinal membrane (ERM) was encountered in 9.1% of eyes (8 eyes) and only 2 eyes (2.3%) had non proliferative diabetic retinopathy(NPDR). After cataract surgery, follow up examinations were done at 1st week, 3rd month, and 6th month. At 1st week follow up, 83 eyes (94.3%) had no change in the preexisting fundus state, while 5 eyes (5.7%) developed an increase in central foveal thickness. At 3rd month follow up, the same percent that experienced no change in fundus status remained the same as 1 week follow up. Additionally, 2 diabetic mellitus eyes (2.3%) developed epiretinal membranes while one of the five eyes with increased cental foveal thickness(CFT) had been normalized. At 6th month follow up, central foveal thickness had been increased in 11 eyes (12.5%). However, the number of epiretinal membrane eyes remained constant (2 cases- 2.3%). The overall patient number who had no change has decreased down to 75 cases (85.2%).
