Optic disc drusen and a constellation of other features of retinitis pigmentosa: a case report
(Science Publishing Group, 2021) Babalola, Y. O.; Baiyeroju, A. M.
Aim: We describe a case of optic disc drusen in retinitis pigmentosa with a myriad of other ocular associations of retinitis pigmentosa coexisting in our patient. To the best of our knowledge, this is the first case reported in a Nigerian. Method: This is a case report of a 16 year old who presented top our eye clinic with a 2 year history of poor night vision with an associated history of difficulty seeing far since childhood. The best corrected visual acuity was 6/18 and 6/12 respectively in the right and left eye. Slit lamp biomicroscopy revealed bilateral grade 1 posterior subcapsular cataracts. Binocular indirect ophthalmoscopy of both eyes revealed vitreous opacities, pale, cupped discs with nasalization of the vessels and yellowish, crystalline deposits at the inferior and superior disc margins. The retina was pale with attenuated vessels, bone spicule pigmentation, atrophic maculopathy and epiretinal membranes bilaterally. Results: An assessment of optic disc drusen, glaucoma, atrophic maculopathy with epiretinal membrane in retinitis pigmentosa was made. The diagnosis of optic disc drusen was confirmed by characteristic ocular B-scan findings. He was commenced on guttae betaxolol BD in both eyes and counselled on the nature of the eye pathology. Conclusion: Optic disc drusen co-exists with retinitis pigmentosa. Though uncommon, optic disc drusen may occur in Africans as seen in our patient. Other ocular associations including myopia, glaucoma and macula lesions like epiretinal membrane and atrophic maculopathy may also be present. The central visual field changes in a patient with retinitis pigmentosa, optic disc drusen and glaucoma may be attributable to all three ocular entities and not just the glaucoma. Prompt diagnosis, follow –up and adequate patient counselling is essential in the management of these patients.
Retinopathy of prematurity in a tertiary facility: an initial report of a screening programme
(Paediatric Association of Nigeria, 2020) Olusanya, B. A.; Oluleye, T. S.; Tongo, O. O.; Ugalahi, M. O.; Babalola, Y. O.; Ayede, A. I.; Baiyeroju, A. M.
Retinopathy of prematurity (ROP) screening in Nigeria is at a nascent stage and at the moment there are no National guidelines for ROP screening in Nigeria. Thus it is desirable for screening programs to report findings amongst screened preterm infants in order to facilitate the development of national ROP screening criteria and guidelines. The aim of this report is to describe the frequency, severity and risk factors for retinopathy of prematurity (ROP) among preterm and very low-birth-weight babies screened within the first year of initiating an ROP screening program at a Nigerian tertiary facility. Methods: A cross-sectional study of infants born at less than 34 weeks gestational age; or with birth weight less than 1500g between May 2016 and May 2017. ROP screening examinations were performed by ophthalmologists with the use of an indirect ophthalmoscope, after pupillary dilation, in collaboration with the neonatology team. Information on gestational age at birth, birth weight, oxygen therapy and presence of other risk factors were recorded and analyzed. Results: A total of 74 infants were screened during the period. There were 36 (48.6%) males. Mean gestational age at birth was 29.6 (±2.35) weeks. Mean birth weight was 1.26 (±0.27) kg with a range of 800 to 1950g. ROP was detected in 9 (12.2%) infants. Two (22.2%) of these had Threshold ROP. There was no significant difference between the mean birth weight and mean gestational age of the infants who had ROP compared to those without ROP. The two infants with Threshold ROP were treated with intravitreal Bevazicumab and had regression of ROP. Conclusion: Retinopathy of prematurity was diagnosed in at risk infants in this facility. There is, therefore, a need to establish ROP screening programs in all neonatal units across the country. In addition, established programs need to evaluate their screening criteria with a view towards developing country-specific screening guidelines.
