Clinical characteristics of exudative age-related macular degeneration in Taiwan

PurposeTo describe the clinical features of exudative AMD of patients in Taiwan.MethodsA retrospective case series consisting of 235 eyes in 211 patients, with a male/female ratio of 7:3, mean age 70.36 ± 8.98 years (range 50–86), with exudative AMD, was reviewed at Changhua Christian Hospital, Taiwan.ResultsAmong the 211 patients, 77 (36.5%) had bilateral involvement of exudative AMD; and of the 235 eyes, 117 (49.7%) were diagnosed with idiopathic PCV, 111 (47.2%) with typical AMD, and seven eyes (2.9%) with retinal angiomatous proliferation. PCV is predominant in patients younger than 70 years (71.8%), whereas typical AMD is prevalent in patients 70 years or older (59.4%). After treatment, mean visual acuity improved in 154 eyes, as reflected in the decreasing logarithm of minimal angle of resolution (log Mar VA)—from 0.95 ± 0.60 to 0.84 ± 0.55, whereas in the other 81 eyes without treatment visual acuity deteriorated—log Mar VA increased from 0.85 ± 0.60 to 1.22 ± 0.53.ConclusionMale predominance, higher ratio of PCV, and lower ratio of retinal angiomatous proliferation are common features of exudative AMD in Taiwan.
