The electroretinogram in Marfan's syndrome.

Marfan's syndrome (MS) is an inherited disease of connective tissue. The most characteristic ocular change is dislocation of lens, but myopia and retinal detachment also can occur. We examined 11 MS patients using electroretinography (ERG). 6 cases showed normal ERG. 5 cases had abnormal ERG. One had retinal detachment. 3 had myopia and 1 case suffered from secondary glaucoma. The defects of visual function were shown by electrophysiological test in those MS patients.

[Preoperative electroretinogram for predicting postoperative visual function of vitrectomy].

Vitrectomy was performed on 17 patients [19 eyes] who had dense vitreal opacity and precluding inspection of the ocular fundus. The preoperative visual acuity was light perception to 0.1, the postoperative visual acuity was 0.03 to 0.9. The preoperative electroretinogram [ERG] was tested on all patients. The correlation of the amplitudes of the ERG b-wave to the postoperative visual acuities were statistically analysed. The results showed that there was positive correlation of the amplitude of the preoperative scotopic bright ERG b-wave to postoperative visual acuity [r = 0.7709, p less than 0.01], and positive correlation of the amplitude of the preoperative photopic ERG b-wave to the visual acuity [r = 0.8086, p less than 0.01]. It suggests that the bigger amplitude of the preoperative ERG b-wave was, the better postoperative visual acuity was improved. Thus, the preoperative ERG could predict the outcome of vitrectomy in various ocular diseases with vitreal opacities and very low visual acuity.
