Impact of Coronavirus Disease 2019 on Intravitreal Antivascular Endothelial Growth Factor Injection Rates in Nigerians.

Aim: To quantify the impact of coronavirus disease 2019 (COVID-19) on the rate of intravitreal antivascular endothelial growth factor (VEGF) injections (IVI) in eye hospitals in Nigeria.

Materials And Methods: A retrospective, observational, comparative study. The IVIs given 12 months before (pre-COVID) and 12 months after the first announcement of the COVID-19 lockdown (COVID) in Nigeria in four hospitals were used as the sample for this study.

Low rates of optical coherence tomography utilization in the diagnosis and management of retinovascular diseases in a lower middle-income economy.

Background: Optical coherence tomography (OCT) is widely used as the standard of care in evaluating macular and retinovascular diseases. However, the degree of OCT utilization is yet to be researched in a resource-limited country where wide gaps exist in access to healthcare.

Aim: To determine the rate of utilization of the OCT in diagnosis, pre-treatment, and post-treatment evaluation of macular and retinovascular diseases treated with intravitreal anti-vascular endothelial growth factor injection (IVI).

Normal central foveal thickness in a thousand eyes of healthy patients in sub Saharan Africa using fourier domain optical coherence tomography.

Background: Optical coherence tomography provides high resolution in vivo images of the retina which are essential for diagnosis and follow up of patients with retina disorders like macula edema and exudative age-related macular degeneration. Establishing the normal range of central fovea values in our population provides vital baseline data for comparison.

Aim: To report the range of normal central fovea thickness measurements in eyes of healthy hospital patients in sub-Saharan Africa using a commercially available Fourier domain optical coherence tomography (OCT) scan.

Are outcomes of surgery for retina detachments from giant tears worse than from other holes and tears in this era of small gauge vitrectomy and perflorocarbon use in Sub-Saharan Africa?

Aims: To report a comparison of clinical features, visual and anatomic outcomes between patients with retinal detachments from giant retinal tears (GRTs) and those from other types of holes and tears undergoing retina reattachment surgery in the same institution within the same time period in sub-Saharan Africa.

Materials And Methods: A retrospective noncomparative case series of patients undergoing primary retina detachment (RD) repair for rhegmatogenous retina detachment (RRD) at Eye Foundation Hospital Retina Institute between January 2014 and December 2018 was done.

Results: A total of 275 eyes of 275 patients met the inclusion criteria.

Trends in glaucoma procedures and surgeries at the eye foundation hospital group, Nigeria.

Aims: To review the trends in glaucoma procedural treatments from January 2009 to December 2017.

Methodology: A retrospective search was carried out from the operating theater and laser room records of the Eye Foundation Hospitals in Lagos, Abuja, and Ijebu-Imushin. Consecutive glaucoma procedures for each year from January 2009 to December 2017 were recorded in the data sheet prepared for the study.
