Abstract
The most common cause of permanent blindness worldwide is glaucoma. Ophthalmologists are paying more and more attention to how glaucoma affects the retinal vasculature. Our study was case control study, included both eyes of 20 patients with unilateral acute PACG for evaluate the papillary and peripapillary retinal vascular density (VD) in eyes with primary acute angle closure crisis (PAACC) and exploring the possible correlation between disc perfusion, neural structure, and visual field damage. We divided them to case group (the diseased eyes) and control group (normal eyes). Our patients were 13 females and 7 males their age ranged from 25.0 – 71.0 years with Mean ± SD; 52.45 ± 11.22. All patients underwent to full routine ophthalmic examination, including VA, BCVA, IOP, anterior segment and posterior segment examination. VF, Oct and OCTA had been done for all cases. We found that IOP was higher and BCVA was lower in the case group than the control group. We noticed that the mean deviation of visual field testing was higher in acute PACG eyes than in unaffected eyes. When the vessel densities in the various sectors were evaluated, we found that the PACG eyes had lower VD than the healthy eyes did in every sector of the peripapillary area. For all VD values, there was a statistically significant difference between control and glaucomatous eyes. The VD in glaucomatous eyes was considerably lower (P 0.003) than in the control group in each of the evaluated sectors. Additionally, we discovered that the glaucoma group’s average RNFL and GGC values were lower than those of the control group.
