Retinal Toxicity from Ectoparasiticide Exposure or Coincidental?

Abstract

Case Report: A 42 Year old male presented with complaints of sudden painless diminution of vision in RE for 3days, after fall of ectoparasticide (DELTAMETHRIN1.25%) in Right Eye. Uncorrected visual acuity in Right eye: counting fingers at 1/2metre, Left Eye: 6/6. Anterior segment evaluation showed Right and Left eye within normal limits. Pupils were 3mm round, regular, reactive to light in OU. Dilated Fundus Examination using indirect ophthalmoscopy showed Right Eye C:D:0.5, A:V 2:3 with subretinal fluid accumulation in macula and Left Eye normal fundus picture. A diagnosis of RE Central serous Chorioretinopathy (CSCR) was made using Optical Coherence Tomography. Discussion: With an incidence rate of 9.9 per 100,000, or roughly six times higher than that of women, CSCR mostly affects men. Acute or subacute central vision loss or distortion is the most prevalent symptom, and it typically affects men between the ages of 20 and 50.With regard to illnesses like CSCR, this case study aims to provide clinicians with more insight into the diagnosis, treatment, and management of pesticide-induced ocular damage. Conclusion: This is rare case of retinal toxicity following exposure to Deltamethrin.For an accurate diagnosis and management of CSCR, it is imperative to comprehend its risk factors, particularly the exposure to pesticides. Emphasizing eye protection and preventative health measures will help us safeguard our vision from environmental risks such as pesticide exposure.
