Summary
Microperimetry effectively evaluates macular function and disease progression by measuring retinal sensitivity. This objective tool aids in understanding vision loss in various macular conditions.
Area of Science:
- Ophthalmology
- Medical Imaging
- Vision Science
Background:
- Macular disease is a primary cause of low vision in Western populations.
- Drusen and pigmentary irregularities are prevalent in rural Northern India.
- Macular disease leads to central vision loss and visual disturbances like metamorphopsia.
Purpose of the Study:
- To assess changes in retinal sensitivity in patients with macular diseases.
- To utilize microperimetry for objective evaluation of macular function.
Main Methods:
- An observational study involving 84 eyes of 52 patients with macular disease (age > 20).
- Microperimetry was employed to measure Mean Retinal Sensitivity (MS) and fixation stability.
- Statistical analysis included mean, standard deviation, and 95% confidence intervals.
Main Results:
- Age ranged from 20-81 years; 62% were male.
- Age-Related Macular Degeneration (AMD) accounted for 50% of cases.
- Varied mean retinal sensitivity levels were recorded across different macular diseases, with fixation stability noted in 64% of eyes.
Conclusions:
- Microperimetry serves as a valuable tool for objectively assessing macular function.
- The technique aids in monitoring the progression of macular diseases.
- Objective evaluation of retinal sensitivity is crucial for managing macular conditions.
