Postretinal Detachment Retinal Displacement: How Best to Detect It?

Area of Science:

• Ophthalmology
• Retinal Imaging
• Macular Displacement

Background:

• Postretinal detachment (RD) macular displacement incidence varies widely, potentially due to imaging methods.
• Fundus autofluorescence (FAF) is a key imaging technique in ophthalmology.
• Detecting macular displacement post-RD is crucial for understanding visual outcomes.

Purpose of the Study:

• To compare the efficacy of two FAF imaging modalities in detecting macular displacement after RD.
• To assess the agreement between confocal scanning laser ophthalmoscope (cSLO) and digital fundus camera (FC) FAF imaging for this purpose.

Main Methods:

• Prospective study involving 70 eyes with macula-involving RDs.
• FAF imaging performed 8 weeks postoperatively using cSLO and FC devices.
• Images graded by two masked graders for hyperautofluorescent retinal pigment epithelium (RPE) ghost vessels indicating displacement.

Main Results:

• Both FC and cSLO FAF imaging showed high gradability (87.1% and 88.6%, respectively).
• Retinal displacement was detected in 61.4% of FC images versus 52.8% of cSLO images.
• Moderate agreement (Cohen's kappa = 0.50) was found between the two imaging modalities.

Conclusions:

• Detection rates of post-RD macular displacement were similar between FC and cSLO FAF imaging.
• Moderate agreement suggests potential differences in sensitivity or visualization between the modalities.
• Both modalities demonstrated good test-retest reliability.
