Changes On The Amsler Grid Test In Patients With Senile Cataract [alterações Na Tela De Amsler Entre Pacientes Com Catarata Senil]

Purpose: To assess the influence of some forms of lenticular opacification in the Amsler grid test among patients suffering from senile cataract. Methods: Randomized, prospective interventional trial. Two hundred patients with senile cataract were evaluated with Amsler grid, measurement of best corrected visual acuity for near distance and far distance, biomicroscopy of the anterior segment and macular region. Results: With a two months minimum of follow-up, the average visual acuity after surgery for far distance among the 200 patients was 0.48 logMAR, 11 (5.5%) had changes in the Amsler grid test before surgery. After surgery, from the 11 subjects with changes in the preoperative Amsler grid test, 10 had no more changes in the Amsler grid. These 10 subjects had postoperative best corrected visual acuity of 20/20, and Jaeger 1, no abnormalities of the fundus having been detected. Under this study conditions, the prevalence of changes in the Amsler grid test was 5.5%, and in 5% of the patients these changes were likely related to cataract whereas in 0.5% they were related to vitreous opacification. Conclusion: Some patient with cataract showed changes in the Amsler grid test that can be directly related to cataract, in the absence of clinically detected macular disorders.6811821José, N.K., Delgado, A.M.N., Arieta, C.E.L., Exequibilidade da cirurgia de catarata em hospital-escola: Em busca de um modelo econômico (1992) Rev Assoc Med Bras, 40 (3), pp. 186-188Thylefors, B., Much blindness is avoidable (1991) World Health Forum, 12 (1), pp. 78-86Thylefors, B., Avoidable blindness (1999) Bull World Health Organ, 77 (6), p. 453Kara-Júnior, N., Temporini, E.R., Kara-Jose, N., (2001) Cataract surgery: Expectations of patients assisted during a community project in Sao Paulo, state of São Paulo, 56 (6), pp. 163-168. , Brazil.
