Microperimetry in patients with central serous retinopathy
German Journal of Ophthalmology
|September 1, 1995
Summary
Visual acuity alone is insufficient for assessing central serous retinopathy (CSR). Fundus perimetry using a scanning laser ophthalmoscope (SLO) effectively measures localized light sensitivity and fixation stability in CSR patients.
Area of Science:
- Ophthalmology
- Visual Neuroscience
Background:
- Acute central serous retinopathy (CSR) can impair visual function beyond simple acuity.
- Symptoms like scotomas, distortion, and waviness affect patient's visual perception.
Purpose of the Study:
- To evaluate the utility of fundus perimetry with a scanning laser ophthalmoscope (SLO) for assessing visual function in acute CSR.
- To quantify localized light sensitivity and fixation stability in CSR patients.
Main Methods:
- Included 21 patients with acute CSR and 19 healthy volunteers.
- Utilized static suprathreshold perimetry with an SLO, presenting stimuli of varying intensities.
- Measured fixation stability by the area encompassing 75% of fixation points.
Main Results:
- Affected areas in CSR patients showed reduced light sensitivity (18-20 dB) compared to healthy eyes (22-24 dB).
- Fixation stability was significantly decreased in CSR-affected eyes (33 +/- 12 min of arc) versus normal eyes (21 +/- 4 min of arc).
Conclusions:
- Static perimetry with SLO is a valuable tool for assessing localized light sensitivity and fixation stability in macular diseases like CSR.
- This technique offers crucial insights for managing central serous retinopathy.
