Contribution of pattern electroretinogram and pattern visual evoked potential in early diagnosis of primary open angle glaucoma.

Pattern electroretinogram (PERG) combined with visual evoked potential (VEP) has become increasingly useful in clinical assessment of the anterior visual pathways. In regard to the PERG dependence on ganglion cell activity, we studied monocular PERG in 36 patients (71 eyes) with intraocular hypertension (6 eyes under topical beta-blockers) and in 10 patients (18 eyes) with advanced glaucoma, to estimate the potential effect of increased IOP on ganglion cells. We recorded simultaneous VEP to evaluate the retino-cortical conduction time. Referring to normal values obtained from 19 eyes (12 subjects), we found clear-cut PERG abnormalities in 20 eyes among ocular hypertensive patients with increased IOP. They were more altered in the advanced glaucomatous group. Two or three control exams were performed in 10 patients every 6 months: however such a short-time follow-up seems too limited to define the ERG prognosis value in this pathology. Comparing the PERG with the clinical routine assessments, we discuss its place in the diagnosis and in the follow-up of patients with ocular hypertension.

Stellar corneal rupture and secondary glaucoma after squash trauma in a keratotomized eye.

We report an unusual dramatic case of stellar ocular rupture after squash blunt in a recently keratotomized eye through weakened keratotomy scars. The early secondary glaucoma, the tension generated by the surgical sutures of the wounds and the use of systemic and topical steroids could explain the reopening of two incisions initially unperforated and the delayed healing procedure. We also stress the benefits of wearing protective eye glasses when playing squash, as well as a strict legislation in Belgium in such an eye-threatening sport.

Surface-wrinkling maculopathy as a potential complication of trabeculectomy: a case report.

We report a case of "crinkled cellophane maculopathy" which developed during the first few days following an uneventful trabeculectomy in a high myopic patient with primary open-angle glaucoma. We suggest pathogenic mechanisms that may have induced such premacular lesions, emphasizing the patient's high myopia combined with a postoperative inflammatory reaction.

[Role of argon laser trabeculoplasty in the treatment of open-angle glaucoma: a 7-year retrospective experience].

We present a retrospective study of 534 Argon laser trabeculoplasty which we realized from January 1983 to July 1990 on 356 primary open-angle glaucoma and secondary open-angle glaucoma patients. Follow-up is ranging from 3 months to 7 years. Photocoagulation was limited to 180 degrees trabecular surface in 300 cases and were completed to 360 degrees in the 234 other eyes. We observed an overall cumulated success rate of 87% at 6 months, which decreased slowly further to reach 32.6% at 6 years. Before laser, the mean intra-ocular pressure was 25 mmHg, this value decreased "a maxima" after 18 months (6.3 mmHg) and slowly increased afterwards but was still significant at 6 years. Some parameters may be of better prognosis: an age equal or older than 65 years, pigmentary dispersion syndrome and pseudo-exfoliative glaucoma. Laser trabeculoplasty associated with hypotensive drugs are an efficient and innocuous technic for controlling open-angle glaucoma; however, after a 30 months mean period, we observe a decrease of their efficiency.
