Purpose: To evaluate the clinical and socio-demographic profile of patients living with glaucoma and receiving care in a tertiary eye center in Zimbabwe. Method: A hospital-based retrospective study of clinical records of glaucoma patients from January 2014 to December 2018. The study involved collating demographic information of patients, visual acuities, (VA) intraocular pressure, (IOP), cup-to-disc ratios, (CDRs), average retinal nerve fibers thickness, (RNFL), cup volume, cup-to-disc area, vertical cup-to-disc ratio, (VCDR), rim area, disc area, glaucoma hemifield test, visual field indices and the management of glaucoma. Results: Nine thousand one hundred and eighty-five (9,185) folders were retrieved. Out of these, 432 (4.7%) qualified for the study and were analyzed. There were 267 (61.8%) males and 165 (38.2%) females. The mean age (± Standard deviation, SD) of the patients was 62.66 ± 15.94 years, (range 10 - 110 years). The means visual acuity (VA): OD =1.30 ± 1.06 Logarithm of the Minimum Angle of Resolution, (logMAR), OS = 1.33 ± 1.06 logMAR; IOP: OD = 29.51 ± 12.89 mmHg, OS: 29.17 ± 12.59 mmHg; CDRs: OD = 0.91 ± 0.14 D, OS = 0.92 ± 0.14 D; and the average RNFL thickness was 72.76 ± 18.26 µm and 71.24 ± 23.17 µm in the right and left eye respectively. The mainstay of treatment was medication only. Conclusion: There were more males than females receiving glaucoma care at the tertiary level. Glaucoma cases included juveniles but the mean age was mostly the elderly. It was characterized by high IOPs, large CDRs, and thin RNFL suggestive of late presentation.

Tele-ophthalmology using portable retinal imaging technology, mobile phone and Internet connectivity offers a solution to improve access to diabetic retinopathy (DR) screening services in sub-Saharan African (SSA) countries where the burden of diabetes is increasing and there is limited access to eye care services and specialists. The Zimbabwe Retinopathy Telemedicine Project (ZRTP) established routine DR screening at a hospital-based diabetic clinic in the urban capital city, Harare. A handheld 'point and shoot' digital camera operated by a trained nurse was used to acquire retina images of 203 diabetic patients. A secured 'store-and forward' approach was set up and used for sharing and transfer of images to a retinal specialist at a remote site for reading. This method enabled detection of non-macular DR (11%), diabetic macular oedema (5%), cataract (5%) and glaucoma (6%) among the patients screened. ZRTP demonstrated the utility of tele-ophthalmology for routine retinal screening for diabetic patients in Zimbabwe who have limited access to eye care services. In addition, ZRTP showed how tele-ophthalmology services can provide an empirical framework for providing patient education, and a platform for research in the detection of DR. This approach could be used as a model to address the DR challenges in other countries in SSA.
