# Characteristics and Prognostic Factors Associated With the Progression of Myopic Traction Maculopathy in Mexican Patients

## TL;DR

This study identifies factors linked to the progression of myopic traction maculopathy in Mexican patients, finding that worse initial vision and staphyloma increase the risk of disease progression.

## Contribution

The study reports the first analysis of MTM progression in a Mexican population and identifies initial VA and staphyloma as significant prognostic factors.

## Key findings

- 24.8% of patients with MTM showed progression during follow-up.
- Initial visual acuity and presence of staphyloma were significantly associated with disease progression.
- The patient-year progression rate was 0.20 ± 0.44.

## Abstract

Background

In this study, the characteristics and prognostic factors associated with the progression of myopic traction maculopathy (MTM) were evaluated in a Mexican population.

Methods

This is a retrospective observational study that analyzed patients with MTM who underwent optical coherence tomography (OCT). Clinical-ocular information, the MTM classification, and initial and final visual acuity (VA) were recorded.

Results

In total, 101 eyes of 84 patients (mean age 63.5 ± 10.7 years) were included (88.1% female and 11.9% male). The mean spherical equivalent was -16.8 ± 6.4 D, axial length was 29.6 ± 2.1 mm, and mean initial VA was 0.8 ± 0.5 logMAR. The mean follow-up time was 25.7 ± 27.6 months. The change in final VA from diagnosis to the last follow-up was +0.1 (0.2) (p = 0.001). Overall, 24.8% of patients progressed, 72.3% did not progress, and 3% showed regression. The patient-year progression rate was 0.20 ± 0.44. Factors associated with progression were initial logMAR VA (p= 0.012) and staphyloma (p= 0.001).

Conclusions

One in four patients with MTM progressed, and the patient-year progression rate was 0.5. The factors associated with disease progression were initial VA and the presence of staphyloma. The characteristics of Mexican patients with MTM are similar to those described in other populations.
