[Glaucoma and pregnancy--review of the literature with a case report].

BACKGROUND

Intraocular pressure usually decreases during pregnancy. Pregnancy-related physiological changes do not seem to cause progression of glaucoma.

PATIENT AND

METHODS

The literature regarding glaucoma, ocular hypertension and pregnancy indexed in Medline is reviewed. In addition, we report on a 35-year-old patient with ocular hypertension and a known glaucoma family history, who was thoroughly examined before, during and after pregnancy (visual fields, optic disc measurements, 24-hours tension profile, sense physiology ["Erlanger flicker-test", pattern-reversal-ERG, blue-yellow-VEP], ocular perfusion).

RESULTS

Visual fields and optic disc measurements did not become worse during pregnancy. Also the other sensory parameters ("Erlanger flicker-test", pattern-reversal-ERG, blue-yellow-VEP) did not deteriorate. Intraocular pressure was reduced by 7 mm Hg during and 2 months after pregnancy. Systolic and diastolic blood velocity of the ophthalmic artery measured by dopplersonography was increased by 60% during pregnancy.

CONCLUSIONS

According to present knowledge pregnancy is associated with decreased intraocular pressure and does not seem to constitute a risk factor for progression of ocular hypertension or primary open angle glaucoma. Whether antiglaucomatous drug therapy during pregnancy is necessary awaits further evaluation.
