Treatment and study plan

Microperymetry

Diagnostic Test

Microperimetry is a procedure to assess retinal sensitivity while fundus is directly examined; it enables exact correlation between macular pathology and corresponding functional abnormality.

M-charts

Diagnostic Test

The M-chart (Inami Co., Tokyo, Japan) is a diagnostic tool developed by Matsumoto to quantify the degree of metamorphopsia in patients with macular diseases.

Primary outcomes

The best-corrected visual acuity (BCVA)

Time frame: 1 to 6 months

Acuity is a measure of visual performance. The eye exam seeks to find the prescription that will provide the best corrected visual performance achievable
Amsler test

Time frame: 1 to 6 months

The Amsler grid, consisting of evenly spaced horizontal and vertical lines, has been widely used since 1947 to test the metamorphopsia.
Central retinal thickness

Time frame: 1 to 6 months

Quantitative thickness measurements derived from the "fast macular scan" algorithm report retinal thickness at several locations including the center point, central subfield, and 4 inner and 4 outer zones of the macula.

Secondary outcomes

Retinal sensitivity

Time frame: 1 to 6 months

Microperimetry is a procedure to assess retinal sensitivity while fundus is directly examined; it enables exact correlation between macular pathology and corresponding functional abnormality. It is a psychophysical method which is rapid, safe and non-invasive.
