Does microperimetry have a prognostic value in central serous chorioretinopathy?

Area of Science:

• Ophthalmology
• Retinal Imaging
• Visual Electrophysiology

Background:

• Acute central serous chorioretinopathy (aCSCR) is a common condition affecting the macula.
• Predicting the chronicity of aCSCR is crucial for timely and effective treatment.
• Subretinal fluid persistence is a key factor in the progression to chronic aCSCR.

Purpose of the Study:

• To determine the relationship between initial retinal sensitivity and the persistence of subretinal fluid in aCSCR patients.
• To evaluate microperimetry as a prognostic tool for predicting the chronicity of aCSCR.
• To identify a specific microperimetry cutoff value for predicting subretinal fluid persistence.

Main Methods:

• A prospective observational study involving 14 patients with a first episode of aCSCR.
• Ocular examination, spectral domain optical coherence tomography (SD-OCT), and MAIA microperimetry were performed at baseline and after three months.
• Receiver operating characteristic (ROC) curve analysis was used to determine the optimal macular sensitivity cutoff for predicting chronicity.

Main Results:

• A macular sensitivity cutoff of 20 dB was identified as the optimal threshold for predicting chronicity, balancing sensitivity and specificity.
• At this cutoff, microperimetry demonstrated 71% sensitivity, 100% specificity, 100% positive predictive value, and 78% negative predictive value for predicting subretinal fluid persistence.
• Patients with aCSCR and microperimetry values below 20 dB had a 4.5-fold increased risk of developing persistent subretinal fluid.

Conclusions:

• Microperimetry, with a 20 dB cutoff, is a valuable tool for predicting subretinal fluid persistence in aCSCR.
• This non-invasive test can assist ophthalmologists in identifying patients at risk of chronicity.
• Early identification allows for timely therapeutic interventions, potentially preventing long-term visual impairment and extracellular damage.
