Abstract
Purpose :
To define the demographic and clinical characteristics of rhegmatogenous retinal detachment (RRD) requiring surgery in Mexico.
Methods :
This was a single center retrospective study of patients with RRD. Data from a computer based patient record system was analyzed (2006-2012). The incidence of RRD and its associations with age, gender, lens status and high myopia were recorded, as well as other involved variables.
Results :
A total of 1300 patients with RRD (687 men and 613 women) were identified from 2006-2012. The mean follow up of these patients on our hospital ended up being 4.31 years. The average age at onset was 47.6 years. The incidence in both genders had its peak at the 50-59 year age group. The initial presenting symptom was sudden visual loss in 33.1% of patients, with 6.1% being asymptomatic. In 14.5% of patients the RRD was associated with recent eye trauma. The right eye eas involved in 53.7% of cases. Concomitant high myopia was noted in 31% of the patients and lattice vitreorretinal degeneration was found in 17.6% of these eyes. Prior cataract extraction was noted in 10.1% of the patients. Finally 72.9% of RRDs were macula-off and only 27.1% macula-on. Several different surgical techniques were also recorded, with scleral buckling being the most commonly performed with 28.4% of all RRD patients.
Conclusions :
RRD incidence has been reported to vary with ethnicity and is strongly associated with increasing age, myopia and certain vitreo-retinal degenerations. This study found myopia, previous RRD and recent eye trauma as important RRD risk factor for Mexicans. Being a potentially blinding condition it is important to study the demographic characteristics as to better prepare for dealing with these patients in clinical practice. In this third-level ophthalmological reference center in Mexico City the clinical experience found 72% of RRDs were macula-off, heralding a negative prognosis. This findings overstate the need for prevention and that better screening must be undertaken to diminish the burden of this disease in the Mexican population.
