[Giant retinal tears: Senegalese experience]

Abstract

Purpose: To appreciate the epidemiological characteristics and to show the therapeutic aspects of the giant retinal tears.

Patients and methods: We conducted a retrospective study from January 2014 to June 2017 on subjects with giant retinal tears. Patients with media opacities limiting examination were excluded.

Results: We identified 17 cases of giant retinal tears. The frequency of detachments related to a giant retinal tear was 17% compared to all retinal tears. The mean age was 50.75 years with a sex ratio (M/F) of 6.5. We found three cases of high myopia, one case of hyperopia and four trauma cases. All patients had a decrease in visual acuity. The average time to consultation was four weeks. The mean intraocular pressure was 8mmHg. The tear was found in the left eye in eight cases and in the right eye in five cases; two cases were bilateral. We performed intraocular surgery in five eyes and laser in four eyes. We achieved anatomical reattachment and functional improvement in all operated patients.

Comments and conclusion: The prognosis of a giant retinal tear remains guarded, especially if patients are seen and treated late. Laser photocoagulation of giant tears remains effective, especially in cases of early diagnosis.
