Graves' orbitopathy: frequency of ocular hypertension and glaucoma.

PURPOSE

To determine the relationship between ocular hypertension and glaucoma in patients with Graves' orbitopathy.

METHODS

A total of 107 patients with a diagnosis of Graves' orbitopathy, followed at the Oculoplasty sector of the University Hospital, Medical School of Ribeirão Preto, were evaluated by applanation tonometry, computed visual campimetry (Humphrey 30-2, Full Threshold) and analysis and photographic documentation of the optic nerve. The patients considered to have the suspicion of glaucoma were re-evaluated 1 year later for diagnostic confirmation or exclusion.

RESULTS

A 3.74% prevalence of ocular hypertension (four patients) and a 2.8% prevalence of glaucoma (three patients) was observed. When considering only patients older than 40 years, the prevalence of ocular hypertension was 5.4% (four patients) and the prevalence of glaucoma was 4.76% (three patients).

CONCLUSION

The present study did not reveal a statistically significant difference in the prevalence of ocular hypertension or glaucoma between patients with Graves' orbitopathy and the general population.
