Pigmented Paravenous Chorioretinal Atrophy: A fortuitous finding in a patient with fronto-ethmoidal mucocoele
(Wolters Kluwer Medknow, 2023) Babalola, Y. O.; Ibiyemi, A. A.
A 56-year-old Nigerian male patient presented to the eye clinic with a six-month history of progressive deterioration of vision in the right eye which was preceded by a one-month history of swelling above the right eye. He had no visual complaints in the left eye and no concurrent systemic illnesses. The best corrected visual acuity was hand movement with accurate light projection in the right eye and 6/6 in the left eye. On ocular examination, a right proptosis with inferotemporal displacement was present. A right relative afferent pupillary defect was noted while the left anterior segment examination was normal. Binocular indirect ophthalmoscopy of the right eye revealed a cup-to-disc ratio of 0.6, temporal disc pallor, peripapillary atrophy, and clumps of pigmentation along the venous arcades with generalized chorioretinal atrophy involving the area of the fovea. The cup-to-disc ratio was 0.4 with mild temporal disc pallor and iridescent spots at the macula with similar features of bony spicule-like clumps in the right eye present along the superotemporal arcade in the left eye. Optical coherence tomography (OCT) scan revealed disorganization of the inner retinal layers with intraretinal reflective foci with back-shadowing and both retinal pigment epithelium and choroidal atrophy. The OCT of the left eye showed a few intraretinal reflective foci and retinal pigment epithelium and choroidal atrophy. From the clinical and OCT findings, a diagnosis of pigmented paravenous chorioretinal atrophy and right fronto-ethmoidal mucocele is made.
X-linked Juvenile retinoschisis presenting with rhegmatogenous retinal detachment in a Male Nigerian Adolescent: A case report
(Wolters Kluwer Medknow, 2022) Babalola, Y. O.; Ibiyemi, A. A.; Oluseye, M. O.
A 15-year-old boy came to the eye clinic with reduced vision in the left eye of a year’s duration and prior trauma. Best-corrected visual acuity was 6/9 and hand movement in both eyes, respectively. The anterior segment examination was essentially normal except for a Marcus Gunn pupil and a polar cataract in the left eye. Goldmann applanation tonometry was 10 and 06 mmHg, respectively, in the right and left eyes. Binocular indirect ophthalmoscopy of the right eye revealed pink disc, normal vessels and the Mizuo–Nakamura phenomenon with a cartwheel appearance at the macula. The left eye had a total retinal detachment with proliferative vitreoretinopathy and retinal tear at 12 o’ clock. Optical coherence tomography revealed posterior vitreous detachment and schitic cavities at the macula in the left eye. A diagnosis of left rhegmatogenous retinal detachment with background X-linked juvenile retinoschisis was made. The patient was advised on a pars plana vitrectomy under guarded visual prognosis.
