Neuron Specific Enolase (NSE) levels are elevated in retinal detachment (RD) patients. This biomarker can indicate retinal neuron injury and potentially assess treatment response in RD.

Area of Science:

  • Ophthalmology
  • Neuroscience
  • Biochemistry

Background:

  • Neuron Specific Enolase (NSE) is a biomarker released during central nervous system (CNS) distress.
  • The retina, being a part of the CNS, may release NSE under conditions of distress.

Purpose of the Study:

  • To measure Neuron Specific Enolase (NSE) levels in subretinal fluid (SRF), aqueous humor, and serum of patients with rhegmatogenous retinal detachment (RD).
  • To investigate NSE as a potential biomarker for retinal neuron injury in RD.

Main Methods:

  • Radioimmunoassay was employed to quantify NSE levels.
  • Samples were collected from 13 RD patients (SRF, aqueous, serum) and control groups (aqueous from cataract surgery patients, serum from healthy individuals).

Main Results:

  • Significantly elevated NSE levels were found in the aqueous humor and serum of RD patients compared to controls (p=0.04 and p=0.005, respectively).
  • NSE was detectable in the subretinal fluid of RD patients, with levels ranging from 50-200 microg/l.

Conclusions:

  • Retinal neuron injury in RD leads to the release of NSE into ocular fluids and serum.
  • NSE has the potential to serve as an indicator of RD disease severity and a tool for evaluating neuroprotective treatment efficacy.
