Juvenile glaucoma is prevalent in urban black populations, with a high rate of positive family history and significant visual morbidity. Effective management requires timely screening, treatment, and consideration of surgical interventions when medical therapy fails.

Area of Science:

  • Ophthalmology
  • Public Health

Background:

  • Juvenile glaucoma presents a significant challenge in ophthalmology, particularly in specific ethnic groups.
  • Understanding its prevalence and visual impact is crucial for targeted public health interventions.

Purpose of the Study:

  • To determine the prevalence and visual morbidity of juvenile glaucoma.
  • To investigate the characteristics of juvenile glaucoma in an urban black population.

Main Methods:

  • A retrospective analysis of 1343 glaucomatous patient files from 1991-2001 at Douala General Hospital, Cameroon.
  • Included 94 patients diagnosed with juvenile glaucoma, with investigations including visual acuity, visual field testing, slit lamp examination, tonometry, gonioscopy, and optic disc assessment.

Main Results:

  • The prevalence of juvenile glaucoma was 0.4%, with a mean age at diagnosis of 26 years.
  • 88.3% had a positive family history; mean intraocular pressure (IOP) was 28.2 mmHg, and mean cup/disc ratio was 0.7.
  • Blindness prevalence was 3.2% monocularly and 33% bilaterally; topical medications and trabeculectomy effectively reduced IOP.

Conclusions:

  • This study confirms a high prevalence of juvenile glaucoma in the black Cameroonian population.
  • Economic factors impact screening and treatment accessibility.
  • Surgery is essential for long-term intraocular pressure control when topical medications are insufficient.
