Aim:
The utility of retinal thickness analysis (RTA) in the primary open-angle glaucoma (POAG) early diagnosis and in the follow-up was evaluated.
Materials And Methods:
The nerve fibre layer thickness was analysed with the RTA by repeated examinations in POAG, ocular hypertension (OH) and healthy subjects (H).
Results:
In the POAG group, a statistically significant reduction of mean retinal thickness (MRT) compared to the H group was evidenced both in the total area examined and in each of the four quadrants. The visual field evaluation classified the POAG group's visual fields in stage 1 and the OH group's visual fields in stage 0.
Conclusion:
RTA reveals a variation of mean retinal thickness, even before a functional and/or morphological optic nerve alteration appears. RTA is a complementary tool with the exams usually applied in the diagnosis of glaucoma, even though the information obtained is not specific for glaucoma.
