Abstract
Background The fellow eye of a retinal detachment is at risk of developing a retinal detachment and other visually debilitating disease. Aim To investigate the rate of bilaterality of retinal detachment (RD), the presenting visual acuity (VA), and the presence of ocular morbidity in the fellow eye of patients with RD. Patients and Methods A multicenter, prospective, cross-sectional study examining the fellow eye of consecutive patients who were diagnosed with different types of RD. The patients were seen within one year and examined in four Nigerian eye hospitals and clinics. Demographics, VA, and clinical findings at the presentation were reported on examination of the fellow eyes. Results Twenty-seven (11.4%) out of 237 patients (264 eyes) had an RD in the fellow eye. The mean age of all study patients was 46.2 ± 16.8 years, M/F: 161 (67.9%)/76 (32.1%). The rates of bilaterality for rhegmatogenous, exudative, and tractional RDs were 4.2%, 11.1%, and 31.1%, respectively. Diagnosis of RD in an eye was associated with a risk of developing fellow eye rhegmatogenous retinal detachment (RRD) (P < 0.001) and tractional RD (P < 0.001), respectively. RRD in an eye was associated with a 17% risk of developing RD in the fellow eye (β = -1.6, OR = 0.202, P < 0.001). The BCVA in the fellow eye of the three types of RD varied significantly (P < 0.001). The fellow eye was blind in 25.2% of RRD, 54.1% of tractional retinal detachment (TRD), and 11.1% of exudative retinal detachment (ERD). Bilateral RD eyes were blind in RRD (85.7%), TRD (71.1%), and ERD (50%). One hundred and seven eyes (40.5%) of the total 264 RD eyes studied had other fellow eye events at the presentation. Conclusion A patient with an RD in one eye is at significant risk of developing a blinding RD in the fellow eye. This risk varies with the type of RD and is highest with TRD. However, RRD, the commonest type of RD, can benefit from prophylactic treatment to the fellow eye RD predisposing lesions.

Abstract
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). Patients and Methods Retrospective, consecutive, and non-comparative case series of eyes diagnosed and treated from Jan 2017 to Jan 2022 for seven macular and retinovascular diseases in five eye clinics in Nigeria. Data extracted include demographics, indication for IVI, eye treated, use or non-use of OCT at the diagnosis (pre-treatment) and after the last IVI (post-treatment), and central macular thickness (CMT) of pre-treatment OCT scans. Results Seven hundred and forty two eyes were diagnosed with retinovascular and macular diseases (389 right eyes and 353 left eyes).The male to female ratio was 430: 312 eyes. The mean age was, 63.89 years (SD 12.58). Four hundred and fifty two eyes (60.9%) had a pre-treatment OCT, 235 eyes (31.7%) had a post-treatment OCT, and 190 eyes (25.6%) had both pre- and post-treatment OCTs. The rate of pre-treatment OCT varied with the diagnosis (P = 0.000); DME had the highest rate, 74.4%, and HRVO had the lowest, 40%. Post-treatment OCT rate varied with the diagnosis (P = 0.009); non-AMD CNVM had the highest rate, 49.1%, and PCV had the lowest, 24.6%. Pre-treatment OCT rate was influenced by clinic location (P = 0.000); higher in clinics having an OCT. Post-treatment OCT was not influenced by clinic location (P = 0.37). A CRVO eye had the highest maximum CMT (1031 microns) of all the pre treatment eyes and the lowest minimum CMT of all the pre treatment eyes was in a BRVO eye (138 microns). Mean CMT was highest in HRVO (475.33 microns) and lowest in CNVM (307.62 microns). Conclusion Though OCT is the standard of care for managing retinovascular and macular diseases, this research quantifies the extent of its use in Nigeria and finds it to be low. A post-treatment OCT rate of 32% suggests that urgent steps are required to improve access to OCT for IVI patients.

Abstract
Importance Despite persistent inequalities in access to eye care services globally, guidance on a set of recommended, evidence-based eye care interventions to support country health care planning has not been available. To overcome this barrier, the World Health Organization (WHO) Package of Eye Care Interventions (PECI) has been developed. Objective To describe the key outcomes of the PECI development. Evidence Review A standardized stepwise approach that included the following stages: (1) selection of priority eye conditions by an expert panel after reviewing epidemiological evidence and health facility data; (2) identification of interventions and related evidence for the selected eye conditions from a systematic review of clinical practice guidelines (CPGs); stage 2 included a systematic literature search, screening of title and abstracts (excluding articles that were not relevant CPGs), full-text review to assess disclosure of conflicts of interest and affiliations, quality appraisal, and data extraction; (3) expert review of the evidence extracted in stage 2, identification of missed interventions, and agreement on the inclusion of essential interventions suitable for implementation in low- and middle-income resource settings; and (4) peer review. Findings Fifteen priority eye conditions were chosen. The literature search identified 3601 articles. Of these, 469 passed title and abstract screening, 151 passed full-text screening, 98 passed quality appraisal, and 87 were selected for data extraction. Little evidence (≤1 CPG identified) was available for pterygium, keratoconus, congenital eyelid disorders, vision rehabilitation, myopic macular degeneration, ptosis, entropion, and ectropion. In stage 3, domain-specific expert groups voted to include 135 interventions (57%) of a potential 235 interventions collated from stage 2. After synthesis across all interventions and eye conditions, 64 interventions (13 health promotion and education, 6 screening and prevention, 38 treatment, and 7 rehabilitation) were included in the PECI. Conclusions and Relevance This systematic review of CPGs for priority eye conditions, followed by an expert consensus procedure, identified 64 essential, evidence-based, eye care interventions that are required to achieve universal eye health coverage. The review identified some important gaps, including a paucity of high-quality, English-language CPGs, for several eye diseases and a dearth of evidence-based recommendations on eye health promotion and prevention within existing CPGs.

Abstract
BACKGROUND Information on the causes and outcome of treatment of vitreous hemorrhage (VH) in sub-Saharan Africa is limited. OBJECTIVES To determine the causes and postoperative vision after vitrectomy for VH. DESIGN A retrospective review of records from consecutive eyes, with VH greater than one-month duration, who had vitrectomy and adjunctive treatment in a retina unit in Nigeria. METHODS We assessed the change between preoperative and postoperative visual acuity, bio data, cause of VH, duration of follow up, and additional treatment. Data was analyzed using SPSS statistical package 17.0 to determine the significance of the change in visual acuity for each cause of VH. A p value <0.05 was considered statistically significant. RESULTS Of the 221 eyes of 219 patients, the common causes of VH were trauma 43 eyes, (19.7%), proliferative diabetic retinopathy, 37 eyes (17.0%) and proliferative sickle cell retinopathy, 30 eyes (13.8%). There was no association between cause and the presenting preoperative visual acuity. There was a statistically significant association between cause of VH and postoperative visual outcome. Postoperative visual improvement was significant for branch retinal vein occlusion, central retinal vein occlusion, proliferative diabetic retinopathy with VH only, proliferative sickle cell retinopathy, and trauma with VH only, p value = 0.000, 0.002, 0.001, 0.039, and 0.000 respectively. Postoperative visual change was not significant in age-related macular degeneration and polypoidal choroidal vasculopathy (p value = 0.155, 0.428 respectively). CONCLUSION Significant improvements in visual acuity can be achieved with active treatment of VH in the majority of cases in Nigeria. This information is useful for discussions on prognosis and agrees with previous studies.

Abstract
Purpose To report incidence, clinical presentation, and treatment outcome of full-thickness macular hole (FTMHs) diagnosed post pars plana vitrectomy. Methods We retrospectively reviewed the demographics, best-corrected visual acuity (BCVA), indication for the primary vitrectomy, time to diagnose the secondary FTMH, optical coherence tomographic (OCT) appearance, and treatment outcome of FTMHs, occurring after vitrectomy performed between January 2019 and December 2020. Results Six of 523 vitrectomized eyes developed FTMHs, an incidence of 1.1%. There were five females and one male, mean age of 56.5 years (range 37–85). The indication for primary vitrectomy was rhegmatogenous retinal detachment (RRD) in three eyes, one eye each for sub internal limiting membrane hemorrhage from a ruptured macroaneurysm, vitreous hemorrhage from polypoidal choroidal vasculopathy (PCV), and pre-insertion of Ahmed glaucoma drainage device (GDD). FTMHs occurred within one week to three months after vitrectomy (time from primary vitrectomy to the identification of the secondary MH was a mean of 1.03 months). Mean BCVA in all six MH eyes was log MAR 0.9 (Snellen: 6/54). Anatomical closure was achieved after one surgery in three eyes, two surgeries in 1 eye, after photodynamic therapy (PDT) in the PCV eye, and one patient declined surgery. The mean BCVA in the four surgically closed MH eyes improved marginally from log MAR 0.82 (Snellen: 6/38) to log MAR 0.72 (Snellen: 6/30), mean follow-up 7.6 months. Conclusion Post-vitrectomy FTMH is rare, and RRD was the commonest indication for initial vitrectomy. We observed that all secondary MHs were closed successfully using the inverted internal limiting membrane (ILM) flap technique with limited improvement in vision. The visual outcome of these secondary MHs trails behind that of idiopathic MHs.

Abstract
Background Spectral Domain Optical Coherence Tomography (SD-OCT) has been used for imaging retinitis pigmentosa (RP) eyes and provides useful information on microstructural changes. Aim To review SD-OCT findings and correlate the central foveal thickness (CFT), outer nuclear layer (ONL), external limiting membrane (ELM), and ellipsoid zone (EZ) with visual function in nonsyndromic RP eyes. Patients and Methods A multicenter, retrospective review of records from consecutive eyes diagnosed to have RP. Biodata, systemic disease, visual acuity, lens status, intraocular pressure, and SD-OCT images were examined. The CFT was categorized into normal (250-299 microns), atrophic (0-249 microns), and edematous (≥300 microns). The ONL, ELM, and EZ within the subfoveal area was assessed and rated as normal, reduced (if less than normal), or absent (if missing). The status of these biomarkers was correlated with visual acuity and statistical analysis performed using Pearson Chi2, P < 0.05. In addition, the vitreomacular interface was examined for the presence of vitreomacular traction (VMT), vitreomacular adhesion (VMA), and epiretinal membrane (ERM). Results Fifty-two RP eyes of 27 patients had SD-OCT images that were used for study analysis. There were 17 males and 10 females; 52% of participants were between 31 and 50 years (age range: 22-77 years). An atrophic retina was the most common finding in 42 eyes (81%); the average CFT in the atrophic group was 175 microns (range: 111-245 microns). There were three eyes with cystoid macular edema, and seven eyes were normal. For the OCT biomarkers, a reduction in ONL and ELM occurred in 69% and 46% of eyes, respectively, while an absence was the most common EZ finding (in 50% of eyes). There was a significant correlation between the presence or absence of the three biomarkers and presenting vision: ONL, ELM, and EZ with P values of 0.000, 0.006, and 0.011, respectively. The CFT had no significant correlation with vision; P = 0.522. Other findings on OCT include ERM 17%, VMA 6%, and VMT 2%. Conclusion This report supports the notion that OCT image reporting on physical retinal structure in RP eyes can be used to predict disease effects on vision. A prospective study to better quantify the degree of structural change and correlate with the degree of functional loss is required for RP gene types in Nigerians and black Africans.

Abstract
AIM To determine the degree of visual loss associated with retinitis pigmentosa (RP) in Nigerians at first ophthalmic clinic presentation METHODOLOGY Multicenter, prospective, cross-sectional study in four collaborating retina clinics within Nigeria between January and December 2018. The primary outcome measure was the World Health Organization’s visual status classification at presentation. Clinical examination, including a Snellen’s visual acuity, refraction, anterior segment examination using a slit lamp biomicroscope, and dilated fundus examination using a +90D or +78D, was done in all consecutive RP patients. We analyzed the data using SPSS (version 22), P < 0.05. RESULTS Of 8614 patients seen within the study period, fiftyfour eyes of 27 patients diagnosed to have RP with a mean age of 44.1years ± 17.6 years (ranging between 5–73 years) constituted the study population. Eighteen (66.7%) were males and 9 (33.3%) females. The hospital-based prevalence of RP was 0.31%. Ten patients (37.0%) presented with myopia. RP was bilateral in all cases and non-syndromic. Bilateral low vision and blindness were noted in 44.4% and 22.2% of patients respectively. CONCLUSION About a quarter of patients with RP presenting to the retina clinics would have some degree of visual morbidity. Educating eye care providers and patients about the disease would improve understanding, encourage early clinic visits, manage visual morbidity and enhance rehabilitation when necessary.

Abstract
PURPOSE: Age-related macular degeneration (AMD) is a leading cause of visual impairment worldwide, and its prevalence may also be on the increase in Nigeria. The purpose of this study is to ascertain the burden and pattern of presentation of AMD in a developing country. METHODS: We conducted a multicenter, prospective study from January to December 2018. Biodata and history of systemic disease were obtained from consecutive patients presenting at four collaborating retina clinics and diagnosed with a retina disease after dilated fundus examination and ocular investigations such as fundus photography, fluorescein angiography, and optical coherence tomography. All eyes diagnosed to have wet and dry AMD were used for the study analysis. RESULTS: Out of 8614 patients, 156 eyes of 78 patients were diagnosed with AMD. The hospital-based prevalence for AMD was 0.91%. The mean age at presentation was 67.9 ± 9.2 years, ranging from 44 to 95 years. A majority (75.6%) of patients were between 60 and 79 years, 53.8% were females. Thirty-two eyes (20.5%) had wet AMD, while 124 eyes (79.5%) had dry AMD. Sixty-one eyes (39.1%) had moderate visual impairment (<6/18-6/60); 58 eyes (37.2%) had normal vision (6/18 and better); while 27 eyes (17.3%) were blind, and ten eyes (6.4%) had severe visual impairment. CONCLUSION: AMD contributes to the burden of visual impairment and blindness in the elderly Nigerian. In Nigeria, AMD occurs more in females and most common between the ages of 60 and 79. Dry AMD is four times more common than wet AMD. About 24% of eyes have severe visual impairment or blindness, while about a third each have a moderate visual impairment and normal vision. Increasing awareness of AMD among the at-risk population will be beneficial in achieving early diagnosis and treatment.

Abstract
Objective To investigate the prevalence and presentation of polypoidal choroidal vasculopathy (PCV) in Nigerians. Methods A cross-sectional, multicenter, hospital-based, descriptive study. Data were collected prospectively between January and December 2018, from consecutive patients diagnosed to have a retina disease at the general outpatient and retinal clinics of four eye departments in Nigeria. All participants had visual acuity, refraction, intraocular pressure, anterior segment examination, and dilated fundus examination. Some patients had fundus fluorescein angiography, optical coherence tomography (OCT), and OCT angiography (OCTA). Systemic comorbidity was determined by medical history and systemic evaluation. Diagnosis of PCV was based on clinical findings, and in some patients using OCT. Results A total of 8,614 patients were seen and 15 patients (18 eyes) were diagnosed to have PCV giving a yearly hospital-based prevalence of 0.17%. The mean age at presentation was 63.27 ± 11.5 years (range 44-84 years). There were nine females (60%). The male: female ratio was 1.5:1. Twelve (66.7%) of the 18 eyes were blind, 16.7% had severe visual impairment while 11.1% had mild visual impairment. Seven eyes (38.9%) had vitreous hemorrhage. Of the 12 blind eyes, 50% had vitreous hemorrhage (P = 0.463). Nine patients (60%) had systemic hypertensive as comorbidity (P = 0.016). Conclusion PCV is a cause of vision loss among Nigerians. Majority of the eyes were blind and 50% of blind eyes had vitreous hemorrhage. Since Indocyanine Green Angiography is the most appropriate imaging technology and is mostly unavailable in Nigeria, efforts should be made to address this need and improve the diagnostic accuracy.

Abstract
PURPOSE: The aim of this study is to investigate the outer retina reconstruction using postoperative spectral domain optical coherence tomography (SD OCT) in large diameter macular holes (MHs) treated with the inverted internal limiting membrane (ILM) flap technique. METHODS: A retrospective study of 14 consecutive eyes that had vitrectomy and inverted ILM flap technique for MHs with a base diameter of 400 μ or greater. Preoperative and postoperative SD OCT images were assessed for MH closure and for outer retina presence; represented by the external limiting membrane (ELM) and ellipsoid zone (EZ), in the subfoveal and parafoveal areas. RESULTS: The average MH base diameter was 963 μ. Postoperative SD-OCT revealed an absence of the outer retina in six eyes, a continuous (regular) presence of the outer retina in four eyes, and a discontinuous (interrupted) presence in four eyes. There was an inverse relationship between MH size and presence or absence of ELM and EZ. A larger MH base diameter size was associated with a higher probability of an absent ELM and EZ (P = 0.04). Eyes in which an outer retina was present postoperatively achieved 6/18 and better vision compared to eyes without (P = 0.08). CONCLUSION: The outer retina in some large MHs treated with ILM flap technique can undergo reconstitution and remodeling which improves over time. The average size for MHs with complete reconstitution was 652 μ, 855 μ for those with interrupted reconstitution, and 1242 μ for eyes with no outer retina reconstruction. This suggests that MHs having a size within the limit of the no outer retina reconstitution MH group may be candidates for other surgical techniques in which postoperative outer retina presence is expected.

Abstract
Aim To present the anatomical and visual outcome and compare different techniques in the surgical treatment of proliferative vitreoretinopathy (PVR) in Nigerians. Method Comparative retrospective review of PVR grade C and D eyes that had vitreoretinal surgery with silicone oil between April 2005 and December 2012. Data was extracted from consecutive case notes after exclusion of eyes with PVR associated with proliferative diabetic retinopathy (PDR), proliferative sickle cell retinopathy (PSCR) and eyes with nonuse of silicone oil. A comparison of the outcome of vitrectomy alone (Vit.), versus combined with a scleral buckle (Vit.+SB), versus with retinectomy (Vit.+RT), versus with all three procedures (Vit.+SB+RT) was done. Statistical analysis was done using the Statistical Package for Social Sciences version 16 software. Pearson Chi-square test and Fisher's exact T-test were used to determine the effect of relationships. Results 138 eyes of 138 patients had grades C (100 eyes) and grade D (38 eyes) PVR. Surgery involved vitrectomy and membrane peel in 53% of eyes, additional scleral buckle in 22%, and retinectomy was performed in 17%. Retinal reattachment rate was 86% for PVR C eyes and 87% in PVR D eyes. There was no statistically significant difference in anatomical outcome between vitrectomy alone and the combination surgeries. In the vitrectomy only category, the postoperative vision was noted to improve (> preoperative), in 48% of PVR C and in 31% of PVR D. 33% of PVR C and 44% of PVR D eyes had a worse vision (< preoperative). Visual outcome was similarly poor in the combination surgeries with improved vision noted in 12%, 44%, and 33% of the Vit.+SB, Vit. +RT, and Vit.+SB+RT PVR C eyes, respectively. In PVR D eyes, improved vision was seen in 57% and 12% of Vit.+SB and Vit.+RT eyes, respectively. Conclusion Surgery results in anatomical reattachment and there is nonsuperiority of any technique. Visual outcome is poor as previously reported. Recent trials of pharmacological adjuncts may show promise for improved visual outcomes.

Abstract
Purpose: To highlight the pattern and treatment outcomes of ophthalmologic disorders referred to a private specialist rheumatology clinic. Methods: Retrospective review (January 2015-December 2016) of referrals from Eye Foundation Hospital, Lagos to Arthrimed Specialist Clinic, Lagos. Case records were retrieved and relevant information extracted. Ethical standards were observed. Results: Twenty-two referrals (35 eyes) were received out of 643 patients (3.4%) seen during the study period. The majority were female (63.6%) with mean age 48.9 ± 19.3 years and bilateral disease (59%). Diagnoses included uveitis (45.5%), optic neuritis (36.4%), non-specific autoimmune eye disease (9.1%), keratoconjunctivitis sicca (4.5%), and giant cell arteritis (4.5%). Treatment was with steroids and immunosuppressive agents. Fourteen patients improved (63.6%), five remained unchanged (22.7%), while three worsened (13.6%). Conclusions: Our patients were mostly fourth-decade females with bilateral disease. Uveitis was the commonest presentation, and two-thirds of the treated patients improved after treatment. Early specialist referral and co-management of severe autoimmune eye diseases are desirable.

Abstract
Recent advances in macular hole surgery have significantly improved the rates of anatomical success. One important advance is the dye-assisted peeling of the internal limiting membrane (ILM) around the hole. In large holes (<400 μ), sometimes, ILM peeling alone is not enough to achieve closure, and this may be improved by inverting part of the peeled membrane and using it to cover the macular hole or inverting and tucking the ILM flap into the hole. In this case report, a patient with large full-thickness macular hole underwent a hole repair with an inverted ILM flap technique. The eye developed a subsequent retinal detachment with large collection of subretinal fluid beneath the repaired hole, but the hole remained intact, suggesting that the adhesive forces binding an inverted flap to the edges of a repaired macular hole appear to be strong enough to maintain structural integrity of the closed hole even in the presence of a macula-involving retinal detachment with large subretinal fluid collection.

Abstract
To report the rare and dramatic event of bilateral macular infarction in a sickle cell hemoglobinopathy (SS genotype) patient, resulting in bilateral severe reduction in visual acuity. Without any intervention, the patient's vision gradually improved over the follow-up period. Central visual field defects however persisted. A 21-year-old male Nigerian, presented with a 1-week history of bilateral sudden painless loss of vision. His symptom was associated with fever, feeling of heaviness in the chest and head, and a dizzy spell. Visual acuity was reduced to 20/200 in both eyes and near acuity was; right eye: N24, left eye: N36. Funduscopy showed a pale, milky white, thickened retinal patch superotemporal to the fovea in both eyes. Fluorescein Angiograph: revealed features consistent with occlusion of the parafoveal terminal arterioles in both eyes. Although he did not receive any ocular treatment, and exchange blood transfusion was not done, he regained near-normal visual acuity in both eyes over a 17-month follow-up period, central visual field defects persisted in both eyes. Visual recovery in this patient demonstrates that macular function could improve over time following macular ischemia, without any treatment. Patients and caring physicians should be aware of this possibility.

Abstract
AIM To review the short-term visual outcome of phacoemulsification in adults with uncomplicated cataracts in Eye Foundation Hospital, Lagos, Nigeria. MATERIALS AND METHODS A retrospective review of records of patients that had phacoemulsification between January 2012 and December 2013 in Eye Foundation Hospital, Lagos, Nigeria, was done. Preoperative visual acuity, refractive aim, intraoperative complications, postoperative unaided, and best-corrected visual acuity at 1 and 3 months were analyzed. Only eyes of adults that had phacoemulsification for uncomplicated cataracts were included in the study, all pediatric cataracts and eyes with ocular comorbidities were excluded. Common ocular comorbidities excluded were corneal opacity/corneal scar, glaucoma, uveitis, pseudo exfoliation syndrome, moderate and severe nonproliferative diabetic retinopathy, macula edema, proliferative diabetic retinopathy, eye trauma, age-related macular degeneration, previous corneal surgery, glaucoma surgery, and previous or simultaneous vitreoretinal surgery. RESULTS A total of 157 eyes of 119 patients who met the inclusion criteria were analyzed. There were 60 (50.4%) females and 59 (49.6%) males, with age range from 31 to 91 years and a mean of 65.3 ± 11.10 years. Only eyes with available data were analyzed at 1 and 3 months postoperatively. In 112 eyes (85.7%), the refractive aim was met, 21 eyes (14.3%) did not meet their refractive aim, 20 eyes (12.7%) were excluded, the refractive aim could not be determined from the records as surgeons did not specify, and in 4 eyes, the required information was missing from the case files. An unaided visual acuity of 6/18 and better was achieved in 134 eyes (85.4%) at 1 month and 126 eyes (85.9%) at 3 months whereas best-corrected vision of 6/18 and better was achieved by 145 eyes (92.4%) at 1 month and 146 eyes (98.0%) at 3 months. CONCLUSION Surgical outcomes after phacoemulsification are comparable with international benchmarks for good outcomes, with 85.4% of eyes achieving within 1 D of spherical equivalent of the refractive aim, 92.4% and 98.0% of eyes also achieving best-corrected visual acuities of 6/18 and better at 1 and 3 postoperative months, respectively. Unaided vision of 6/18 and better was also achieved in 85.4% and 85.9% at 1 and 3 postoperative months, respectively.
