Abstract

Background and Aims: Cataract surgery is the commonest eye surgery performed worldwide. Endophthalmitis is a sight threatening complication of surgery which causes reduced vitreous clarity and media opacities and precludes visualization of the posterior segment. Ultrasonography is done in cases of suspected endophthalmitis with poor media clarity. This study aims at evaluating, baseline sonographic features of acute post-cataract surgery endophthalmitis and its association with initial vision, final visual outcome and microbiological profile.

Materials and Methods: This prospective study conducted at Aravind Eye Hospital, Madurai, South India, included all patients who presented with clinical symptoms and signs of endophthalmitis, between January 2014 to December 2015. They underwent A-mode and B-mode ultrasonography and were managed with either ‘tap and inject’ strategy or primary vitrectomy and followed up for three months. The sonographic features like vitreous opacities, vitreous membranes, retinal detachment, choroidal detachment, posterior vitreous detachment, and retino-choroidal thickening were documented and their association with vision at presentation, microbiological profile and final visual acuity was studied.

Results: There were 54 patients (54 eyes), their mean age was 59.9 ± 19.2 years and male : female ratio was 1:1. Of them, 33 patients (61.1%) had dense vitreous opacities, 16 patients (29.6%) had dense vitreous membrane, 3 patients (5.6%) had retinal detachment and 1 patient (1.9%) had choroidal detachment. Median retino-choroidal thickening was found to be 1.82 mm (1.67-1.96 mm). Increased retino-choroidal thickening (P = 0.049) and dense vitreous opacities (P = 0.000) was significantly associated with poor initial presenting acuity. The occurrence of retinal detachment was significantly associated with poor final vision (P = 0.006) and infection by virulent organisms (P = 0.028).

Conclusion: In conclusion, sonographic warning signs are associated with infection by virulent organisms and poor visual outcome.
