# Trends in glaucoma practices among a cohort of ophthalmologists in Latin America: A survey-based study

## TL;DR

This study surveyed Latin American ophthalmologists to understand their glaucoma care practices, tools used, and work-related perceptions.

## Contribution

The study provides insights into current glaucoma evaluation practices and perceptions among ophthalmologists in Latin America.

## Key findings

- Goldmann tonometer is the most used and trusted method for intraocular pressure measurement.
- Humphrey visual fields are the primary tool for perimetry in glaucoma evaluation.
- Most ophthalmologists work in the private sector and have mixed feelings about their compensation.

## Abstract

To descriptively assess clinical preferences, practice patterns, and demographic characteristics related to glaucoma care among a cohort of ophthalmologists in Latin America, through a structured survey focusing on intraocular pressure measurement methods, visual field testing, and work-related perceptions.

A cross-sectional survey was conducted to assess the clinical practices of ophthalmologists who attended the XLVI Inter-American Course in Clinical Ophthalmology (CURSO) at the Bascom Palmer Eye Institute. The survey collected demographic and professional data, as well as information on practice patterns, preferences, and beliefs related to glaucoma evaluation. The responses were categorised and analysed to identify trends in clinical practices.

In a survey of 142 Latin American ophthalmologists attending the XLVI Inter-American CURSO, the Goldmann tonometer was the most used, preferred, and trusted method for IOP measurement. Humphrey visual fields were the predominant tool for perimetry. Sixty-three percent reported having an assistant to assess basic parameters like visual acuity and IOP. Most participants (90%) worked in the private sector; 51% considered their compensation fair, while 27% felt undercompensated. Retirement age expectations varied, with most planning to work until at least age 70.

Glaucoma evaluation results from this survey may reflect Latin American practice patterns. Based on this assumption, Goldmann and Humphrey are the most popular tools for measuring IOP and conducting perimetry, ophthalmic assistants often assess basic eye parameters, and ophthalmologists report varying satisfaction with their income and retirement age.
