Purpose:
To report a series of central retinal artery occlusions (CRAO) following cataract surgery complicated by posterior capsular rupture (PCR).
Methods:
Data from 14 patients with acute CRAO following cataract surgery was collected for this study including subject demographics, initial and final best-corrected visual acuity, systemic investigations, optical coherence tomography (OCT) and fundus fluorescein angiography (FFA) findings.
Results:
Mean subject age was 59.9 ± 12.1 years. Male: Female ratio was 1:1. All patients were operated between October and November 2015 and presented with acute vision loss 1 to 4 days after surgery. All the patients underwent cataract surgery under peribulbar anesthesia and had PCR for which anterior vitrectomy (AV) was done. In all the cases Ethylene oxide (ETO) sterilized vitrectomy probe was used for AV. Clinical picture of CRAO was noted in all the cases during the immediate postoperative period. OCT showed inner retinal layer hyperreflectivity while FFA was normal in all the cases. The final visual acuity was poor in all the eyes. This paper discusses the possible mechanisms of CRAO in these cases.
Conclusion:
CRAO is a potential complication of peribulbar anesthesia for intraocular surgery in patients with vascular risk factors and hence any substance that can aggravate the vasospasm in such patients should be used cautiously. Vasospasm could be caused by ETO as residual ETO could be present in the vitrectomy machine tubing causing toxicity. It is recommended to be cautious while using ETO sterilized instruments for cataract surgery.
Purpose:
To identify the reasons for delayed presentation among patients with sight-threatening diabetic retinopathy (STDR) and to assess their knowledge, attitude, and practice (KAP) patterns in context to diabetes mellitus (DM) and diabetic retinopathy (DR).
Methods:
Single-center, cross-sectional, questionnaire-based KAP survey. All consecutive cases of STDR who presented to our tertiary eye care facility from June 2020 to November 2020 were recruited. The KAP scoring survey tool was incorporated into the questionnaire to help evaluate and represent the patient's disease.
Results:
170 patients with STDR were enrolled in the study. The mean age of patients was 54 ± 9.34 years (Range: 21–70 years); 110 patients (64.7%) were between 41 and 60 years; 131 patients (76%) had DM for more than 5 years. The STDR changes were more prevalent in patients with an educational qualification of high school or less (
n
= 142; 83.5%). Fifty-two patients (30.6%) had been informed regarding the detrimental effect of diabetes on the eyes and were recommended to consult an ophthalmologist by the treating physician. Of these, 24 (46.15%) patients were educated about retinal changes due to diabetes. Eighty-five (50%) patients in our study had good knowledge about DM; 13 (7.6%) patients had good knowledge about DR. For patients not compliant for follow-ups with the treating physician, the use of “home glucometers for self-monitoring (
n
= 60, 35.3%) was the most prevalent reason. The main reason for poor compliance for undergoing a dilated fundus examination by the ophthalmologist was “Had good vision, so didn’t feel the need” in 143 (90.5%) patients.
Conclusion:
The absence of visual complaints, lack of knowledge, and failure to undergo a dilated fundus examination in the past were the prevalent risk factors in patients presenting with STDR. Knowledge/practice about DR was poor among the patients with STDR. The treating physicians and ophthalmologists were the most common sources for patient education.
