Visual disability among patients attending glaucoma clinic in a tertiary hospital.

PURPOSE

To report visual impairment and blindness among the patients attending a glaucoma clinic in a tertiary university hospital and highlight the possible risk factors that could be addressed later.

METHODS

A retrospective analysis of the medical records of the patients attending the glaucoma clinic in Ain Shams University Hospitals over a period of one year was conducted. Visual impairment classification was done according to the International Classification of Diseases and Related Health Problems (ICD-11) based on the best-corrected visual acuity in the better-seeing eye. Data including diagnosis, history of previous surgery, and duration of glaucoma were extracted and analyzed.

RESULTS

The medical records of the first visit of 118 patients (58 males and 60 females) were included in this study. Secondary glaucoma was the most common type presented (38 patients, 32.2%), followed by primary open-angle glaucoma (35 patients, 29.6%). Sixty-seven patients (56.7%) were considered visually impaired, while seven patients (5.9%) were considered blind. Forty-one patients (34.7%) were considered mono-ocular blind.

CONCLUSION

There is a high incidence of visual impairment and blindness among glaucoma patients presented to the glaucoma clinic in the  tertiary hospital. A further nation-wide study and possibly, an early surveillance program for glaucoma are needed.
