The provided UK guideline excerpts do not specifically detail referral criteria for Branch Retinal Vein Occlusion (BRVO) ,,,,,. However, based on principles for other acute retinal conditions, you should consider an urgent referral to an ophthalmologist for further evaluation and treatment if a patient presents with:

  • Rapid onset visual loss ,.
  • Visual distortion (metamorphopsia) ,.
  • Visual field loss or changes in visual acuity .

The basis for urgent referral in such cases is that treatments are available in secondary care that should be given as soon as possible to prevent visual loss ,. Hospital eye services are equipped to provide diagnosis and treatment for eye conditions .
