Retina evaluation with non mydriatic ultra wide field color imaging after cataract surgeries in asymptomatic patients

Abstract

 

Purpose

 

To evaluate the role of ultra wide field (UWF) color fundus photography as a screening tool in the follow up of asymptomatic patients after cataract extraction (CE) surgeries.

 

Methods

 

A retrospective, observational case series. We reviewed the electronic medical records to identify patients who underwent CEs. Patients were included in the study if they were followed with non mydriatic UWF retinal imaging (Optos 200TxTM) in the postoperative period and had no new visual symptoms. Images were reviewed by a retina specialist and graded according to largest field of view and clarity. The main outcome measure was the detection of peripheral retinal lesions including retinal breaks and detachments. Secondary outcomes were image quality and the association between retinal findings and peri operative risk factors.

 

Results

 

76 eyes of 58 consecutive patients were enrolled. Mean age was 66.6±12.3 years. Female to male ratio was 1.5:1. 46.9% of eyes were myopic. Only 2.2% had complicated surgeries. Imaging was performed 1- 13 weeks (average of 4.17 weeks) after surgery at physician discretion. The UWF retinal imaging allowed for a good visualization of the peripheral retina in more than 90% of our patients. We did not find any new retinal breaks and/or detachments in any study eyes.

 

Conclusions

 

Non mydriatic UWF color retinal imaging was found to be a useful screening tool in the follow up of asymptomatic patients after CEs in our series. Our study represents a supplementary step in the continued evaluation of the role of UWF imaging in peripheral retinal lesions. Further prospective large scale studies are needed.

 

 

Patient # 23 66 y M, OS. History of retinal detachment treated with a primary scleral buckle and cryotherapy. Optos image was taken 39 days after an uneventful cataract extraction surgery. Note buckle impression with extensive cryotherapy (white arrow) and lattice (black arrow). No new retinal breaks or detachment were found.

 

 

Patient # 7 64 y F, OS. High myopia (Axial length- 30.5mm). Optos image was taken 8 days after an uneventful cataract extraction surgery. Note posterior vitreous detachment in the periphery (black arrow) ,Weiss ring floater (black arrowhead) ,peripheral pigmentary changes (white arrowheads) and a choroidal pigmentary lesion (white arrow). No new retinal breaks or detachment were found.
