Summary
Two patients presented with asymptomatic preretinal macular fibrosis, a condition potentially originating from embryonic development. This differs from typical idiopathic fibrosis, as vision and diagnostic tests remained normal.
Area of Science:
- Ophthalmology
- Retinal Diseases
- Embryology
Background:
- Preretinal macular fibrosis is an eye condition affecting the macula.
- Idiopathic forms of this condition are more commonly documented.
- Asymptomatic cases are often discovered during routine eye examinations.
Purpose of the Study:
- To describe two unique cases of asymptomatic preretinal macular fibrosis.
- To investigate the potential embryonic origin of these specific retinal defects.
- To differentiate these findings from commonly observed idiopathic preretinal fibrosis.
Main Methods:
- Case study of two adult patients with asymptomatic macular lesions.
- Ophthalmic examination including visual acuity, fluorescein angiography, and Amsler grid testing.
- Analysis of lesion characteristics and comparison with known retinal development processes.
Main Results:
- Two patients (35-year-old female, 36-year-old male) exhibited asymptomatic preretinal macular fibrosis in their left eyes.
- A gray fibrotic membrane extended towards a lamellar hole in the macular region.
- Visual acuity, fluorescein angiograms, and Amsler grid tests were normal for both individuals.
Conclusions:
- The observed macular defects may stem from early embryonic development, specifically from primary vitreous body adherence to the retina.
- These findings suggest a distinct etiology compared to idiopathic preretinal fibrosis.
- Further research into congenital retinal anomalies is warranted.
