Impact of preoperative posterior segment evaluation on surgical intervention in camp patients

Abstract

Purpose: To retrospectively study impact of preoperative posterior segment evaluation on surgical intervention in camp patients recruited for cataract surgery in Gujarat India. Methods: Retrospective analysis of six months data collected from hospital electronic medical record (EMR) system of 9820 admitted patients recruited from screening camp for cataract surgery from 1/10/2019 to 31/3/2020 in Tertiary Eye Hospital in Gujarat, India, has been done. Comprehensive clinical evaluation, of both anterior and posterior segment which included detailed history; best corrected visual acuity (BCVA); intraocular pressure measurement with non-contact tonometer (NCT) and when required with Goldman applanation tonometer; slit lamp examination; and fundus examination with + 90 diopter lens as well as indirect ophthalmoscope as and when indicated. In case there was no view of retina, a B-scan ultrasound was done to rule out any posterior segment pathology. Immediate surgical intervention done was assessed and results analyzed in percentage. Results: Cataract surgery was advised for 8390 patients (85.43%). Surgical intervention for management of glaucoma was done for 68 patients (0.692%). Retina intervention was done for 86 patients. Posterior segment evaluation changed immediate surgical plane of management for 154 (1.57%) patients. Conclusion: Comprehensive clinical evaluation is economical and should be mandatory especially in community services as comorbid conditions like glaucoma, diabetic retinopathy, retinal vein occlusion, and other varied posterior segment diseases contribute significantly to visual disability in elderly age group. It is difficult to follow these patients later if manageable comorbidity is not informed about and if indicated dealt simultaneously for visual rehabilitation of patient.
