Eye cancers at the guinness eye center Onitsha, Nigeria

Objectives: To describe the hospital incidence and pattern of ocular and adnexal cancers at the Guinness Eye Center, Onitsha. Materials and Methods: The case files of all new patients seen with ocular and adnexal tumors at the Guinness Eye Center, Onitsha, between 2005 and 2017 were reviewed. Those with histological diagnosis of malignancy were selected and analyzed. Information obtained included age, sex, disease duration, diagnosis and co-morbidity. Results: There were 85 patients (0.1% of all the new patients), made up of 42 males and 43 females. The median age was 5 years; range: 5 months­70 years. The commonest cancers were retinoblastoma, 45 patients (52.9%) and conjunctival squamous cell carcinoma, 30 (35.3%). Twenty eight (93.3%) squamous cell carcinoma patients were HIV-positive. No child had squamous cell carcinoma. All retinoblastoma patients were aged ≤6 years. Conclusions: The incidence of ocular and adnexal cancers at the Guinness Eye Center, Onitsha, was low with retinoblastoma and conjunctival squamous cell carcinoma accounting for most of the cancers. While retinoblastoma would most likely be suspected in a child with ocular tumor, young adults with squamous cell carcinoma should be evaluated for HIV infection. Since these lesions threaten sight and life, the public should be educated on the early signs of the diseases and the need to report to hospital early

Outcome of surgery for Rhegmatogenous Retinal Detachment In a Nigerian eye hospital.

AIMS AND OBJECTIVES: To determine the treatment outcome of rhegmatogenous retinal detachment at the Guinness Eye Centre Onitsha, Nigeria. MATERIALS AND METHODS: Case files of patients who had surgery for rhegmatogenous retinal detachment at the Guinness Eye Center Onitsha between June 1997 and May 2012 were reviewed. Information obtained included age, sex, presenting and post-operative visual acuity, anatomical reattachment, post- operative complications and causes of treatment failure. RESULTS: Fifty four patients, 33 males and 21 females, age range: 48-79 years, median-56 years, had surgery. Three patients had giant retinal tears; 10 patients also had proliferative vitreo-retinopathy(PVR). Symptoms duration was 7 days to 18 months; median-7 months; the post-surgery follow-up was 9 months to 6 years; median -2 years.While 47(87%) patients had pre-operative visual acuity<3/60 in the affected eye, post-operatively 48(88.9%) patients achieved acuity e" 3/60, with 14(25.9%) attaining uncorrected visual acuity of 6/9 - 6/18. The retina remained attached 6 months after surgery in 45(83.3%) patients.The post- operative complications included re-detachment, 12(22.2%) patients, cataract, 5(9.3%), exposed explant, 2(3.7%), suture granuloma, diplopia and retinal haemorrhage, 1(1.9%) patient each.The surgical failure in the 12 patients were were due to PVR (9 patients) and missed retinal holes (3 patients). CONCLUSIONS: Despite poor infrastructure and late presentation by patients, the anatomical and visual results of surgical treatment of rhegmatogenous retinal detachment using cryo-retinopexy and scleral buckling technique are encouraging. Better results would be expected if patients presented early and facilities for vitrectomy provided for tackling complex detachments.
