To determine the frequency of symblepharon, causes, time of evolution, surgical treatment and complications in a mexican-mestizo population.
Retrospective, transversal, descriptive, observational. We revised 250 files of patients previously diagnosed with symblepharon, from January 2007 to January 2008 in Asociación para Evitar la Ceguera en México and with a minimal follow up of one year.
Patients consisted of 40 females (62.5%) and 24 males (37.5%), with a mean age of 41 years. The most common cause was a burn injury (especially chemical burn) in 30 patients (46.87%), followed up by previous surgery in 29 patients (45.31%). 2 or more quadrants were affected by symblepharon in 59 patients (92.18%) and 58 patients (90.62%) had corneal involment. More than one year of evolution of the symblepharon was shown in 34 patients (54.68%). The initial treatment in 45 patients (70.31%) was observation and in 51 patients (74.68%) a surgery was performed into the first three months after the diagnosis. Conjunctival autograft was performed in 22 patients (34.37%) being the most frequent treatment and a conformator used in all of the procedures. The most common complication was recurrence of symblepharon, in 17.18% of the cases.
Burn injuries and history of previous surgery were the most common causes for the development of symblepharon. Conjunctival autograft was the most employed surgical treatment.
