RESUMO
OBJECTIVE: To describe the characteristics, upon presentation, of a cohort of Hispanic patients with birdshot retinochoroidopathy. METHODS: A retrospective chart review of Hispanic patients with birdshot retinochoroidopathy of was performed. The demographic and clinical characteristics were analyzed. RESULTS: Nine patients who met the research criteria for a diagnosis of birdshot retinochoroidopathy were identified and included in the analysis, all of whom were HLA-A29 positive. The median age of the cohort upon presentation was 52 years; 89% of the patients were female, and all were Hispanics. Ninety-four percent of the eyes had an initial visual acuity of 20/50 or better, while 72% had measured 20/25 or better. Sixty-one percent of the eyes had retinal vasculitis, which was bilateral in 83% of the cases. Thirty-three percent of the patients had, upon presentation, evidence of cystoid macular edema, which was always bilateral. All the eyes had the typical birdshot lesions, at presentation. CONCLUSION: Birdshot retinochoroidopathy can be found in Hispanic patients. Our study suggests that the characteristics upon presentation in Hispanics may be similar to those of Caucasian cohorts.

OBJECTIVE: To describe the characteristics upon presentation of a cohort of Hispanic patients living in Puerto Rico with ocular mucous membrane pemphigoid (MMP). METHODS: Retrospective chart review of subjects with ocular MMP at one academic institution and one private practice. Patients with clinical evidence of ocular MMP, along with a positive mucous membrane biopsy revealing linear antibody or C3 deposition in the basement membrane zone, or with a positive indirect immunofluorescence assay were included. Descriptive statistical analysis was performed. RESULTS: Eight patients with ocular mucous membrane pemphigoid were identified. The median age upon presentation was 60.5 years; however, 2 patients were in their 4th decade and one in the 5th decade of life. Females constituted 62.5% of the cohort. All patients presented with stage III ocular MMP in at least one eye and 50% had history of trichiasis. Seven out of eight patients (87.5%) had extraocular symptoms for a median duration of 36 months (range 2-144 months). The most common site of extraocular involvement was the oropharynx, present in 87.5% of patients. CONCLUSION: Our results suggest that in Puerto Rico ocular MMP most commonly presents in the seventh decade of life. The presence of symblepharon, trichiasis or oropharyngeal mucosal disease should prompt further evaluation and consideration for immunopathological tissue analysis and an IIF assay.
