22 patients
The diagnosed full thickness macular hole and psuedophakia.
Exclusion Criteria:
macular pseudohole, non-full thickness macular hole, retinal detachment, other ocular comorbidities.
Group of 22 patients who underwent vitrectomy due to macular hole
Diagnostic Test: Microperymetry · Diagnostic Test: M-charts
Microperimetry is a procedure to assess retinal sensitivity while fundus is directly examined; it enables exact correlation between macular pathology and corresponding functional abnormality.
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.
The best-corrected visual acuity (BCVA)
Acuity is a measure of visual performance. The eye exam seeks to find the prescription that will provide the best corrected visual performance achievable
Time frame: 1 to 6 months
Amsler test
The Amsler grid, consisting of evenly spaced horizontal and vertical lines, has been widely used since 1947 to test the metamorphopsia.
Time frame: 1 to 6 months
Central retinal thickness
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.
Time frame: 1 to 6 months
Retinal sensitivity
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.
Time frame: 1 to 6 months
