Currently there is a dearth of epidemiological data of age-related macular degeneration (AMD) in Latin America. The purpose of the current study is to report the presenting demographic, clinical, angiographic and tomographic characteristics of patients with exudative AMD seen in a retina referral practice in Costa Rica
Retrospective study of 152 patients (197 eyes) diagnosed with exudative age-related macular degeneration that were evaluated with fluorescein angiography, indocyanine green angiography and optical coherence tomography.
This cohort consisted of 86 female and 66 male patients, 45 (29.6%) patients presented with bilateral disease. The mean age was of 73.4 ± 8.2 yrs. Systemic co-morbidities included 20 (13.2%) with diabetes mellitus, 1 with stroke, and 102 (67.1%) with systemic hypertension. The mean logMAR BCVA at baseline was 0.94 ± 0.72. There were 15 (7.6%) RAP lesions, 4 peripapillary CNV, 33 (16.8%) PCV lesions, 55 (27.9%) type 2 CNV and 90 (45.7%) type 1 CNV. PEDs were seen in 118 (60%), 102 (51.8%) eyes had subretinal fluid present, 14 (7.1%) had an epiretinal membrane, 11 (5.6%) had cystoid macular edema, only 2 (1%) had vitreomacular traction and 20 (10.2%) had atrophy and 90 (45.7%) had disruption of the outer retina.
Most patients with exudative AMD suffer from systemic hypertension and present with advanced disease. The most common type of CNV is type 1 and the most common lesion type seen was a PED.
