[Benign concentric annular macular dystrophy].

CLINICAL CASES: Two cases of benign concentric macular dystrophy are described. In one case, ophthalmologic examination, fluorescein angiogram and visual field measurement were performed. The presence of a juxtafoveal fibrosis in the other patient, indicate that choroidal neovascularization may be associated with this type of macular dystrophy. DISCUSSION: Benign concentric macular dystrophy is an entity with well-defined ophthalmoscopic and angiographic characteristics. Usually the prognosis is good. Rarely, choroidal neovascularization can be associated with this macular dystrophy.

[Prevalence of drusen in homes for the elderly].

PURPOSE: To establish the prevalence of drusen in a population of over-65 year subjects residing in institutions. MATERIAL AND METHOD: A medical interview, ophthalmological examinations and midriatic retinography were performed in 392 older-than-65 year subjects living in homes for the elder (784 eyes). Each eye was reviewed by means of the Wissconsin Age-Related Maculopathy Grading System, in order to determine drusen frequency. RESULTS: Druses frequency totalled 33.3%. A great trend to symmetry was observed; bilateral in 23% of patients. The most frequent finding was multiple units (40 to 59 per eye), well defined soft drusen of 125 micrometer in size, which showed very little tendency to confluence. Twelve to 24% of macular area was affected by drusen. Subjects between ages of 65 to 74, presented the highest frequence. Drusen decreased with age from 75 years upwards. CONCLUSION: The observed drusen frequency found appear lower than those described in other studies outside our country, perhaps due to higher prevalence of media opacities. Midriatic retinography can be a good screening method for the detection of drusen.

[Intraocular pressure asymmetry and related factors in pseudoexfoliative syndrome].

PURPOSE: To determine the intraocular pressure (IOP) asymmetry in pseudoexfoliative (PSX) syndrome and glaucoma patients. To analyze the association between IOP asymmetry and clinical signs. METHODS: 191 patients were prospectively studied, 75 (39.3%) with PSX syndrome and 116 (60.7%) with PSX glaucoma. IOP, visual field test, pigment and PSX material deposit in anterior segment structures were observed and compared between both eyes. The relation between IOP and clinical sign asymmetry was analyzed. RESULTS: IOP asymmetry was less than 10 mm Hg in 138 cases (72.25%) and more than 10 mm Hg in 53 (27.75%) cases. The greatest asymmetry was found in unilateral PSX glaucoma patients (p= 0.001). Visual field test asymmetry was related with IOP asymmetry (p=0.0001). Also, IOP asymmetry was associated with pigment deposit in trabecular meshwork, in Sampaolesi line, and with pupillary atrophy asymmetry (p<0.05). PSX material deposit was not related with IOP asymmetry. CONCLUSIONS: IOP asymmetry is greater in unilateral PSX glaucoma patients. The association between IOP and visual field test asymmetry found in this study suggests that PSX glaucoma is pressure dependent. IOP seems to be related with pigment deposit in anterior segment structures in PSX patients. However, this association was not found with PSX material deposit.
