Abstract
Introduction:Pterygium is a conjunctivovascular proliferation, of the bulbar conjunctiva that encroaches on the cornea, triangular in shape with a canthal base and corneal apex; It is one of the most common benign ocular surface pathologies in the world.The distribution of pterygium is global, but its prevalence is higher in countries with hot and dry climates.Objective:To determine the epidemiological, clinical and therapeutic aspects of pterygium as well as its recurrence rate after surgical treatment at the ophthalmology center of the Sheikh Zayed Hospital in Nouakchott.Results:During our study, we collected 146 cases of pterygium, a frequency of 7.52%. More than half, or 62.3%, of our patients were women, with a sex ratio of 0.6. The age group over 60 years old was the most represented with 34.24%.eye redness and watery eyes dominated the warning signs with 85.6% and 60% respectively. Stage I was in the majority with 43%. Nasal pterygium was the most common with 93.7%. 67.1% of patients in our series benefited from medical treatment alone and 32.9% from excision with conjunctival autograft in 50% of cases.We recorded an average recurrence rate after 18 months of surgery of 12.5% for patients who underwent excision with conjunctival autograftand the rate was higher in patients operated on by other surgical techniques.Conclusion:Pterygium, although benign, is a real public health problem in our countries, because of the high prevalence and the risk of recurrence which remains high for all surgical techniques. In our series, the recurrence rate after 18 months was lowest with limbo-conjunctival autograft.
