ABSTRACT
Purpose: The aim of this study was to describe the management of a case of malignant melanoma of the conjunctiva at the National Hospital of Zinder in Niger and review of the literature. Observation: This was a young adult, 46 years old, male, from Agadez, with an unfavorable socioeconomic status, with no particular history referred for an upper left eyelid tumour. On examination, his general condition was preserved. On inspection, a mass hanging from the free edge of the left upper eyelid was noted; resulting in total mechanical ptosis preventing examination of the condition was preserved. On inspection, a mass hanging from the free edge of the left upper eyelid was noted, resulting in total mechanical ptosis preventing examination of the anterior segment. Palpation of the orbital rim did not note anything in particular, the lymph node areas were free. On the ophthalmological examination, on the right the visual acuity from afar without correction was 10/10 with a normal biomicroscopic examination, on the left the visual acuity was counting the fingers at one meter and a biomicroscopy hampered by the ptosis The assessment laboratory was normal, the orbitocerebral computed tomography showed the conjunctival origin of the tumor without notion of extension in the vicinity. Macroscopically complete excision was performed. Histopathological examination of the approximately 5 cm surgical specimen noted a malignant melanoma of the conjunctiva with impregnation of the margins (R1 resection). Adjuvant treatment with mitomycin C was instituted. The postoperative course was simple. After 6 months of postoperative follow-up, the ophthalmological examination was normal and the search for metastases was negative. Conclusion: Malignant melanoma of the conjunctiva is a rare neoplasia that can mimic a palpebral tumor. Histopathological examination remains important for treatment and monitoring.

ABSTRACT
Purpose: To assess the load of non-urgent and true emergency cases presenting in Emergency department of tertiary eye center in Nepal. Methods: retrospective, descriptive study was done for all emergency visits at Hetauda community eye hospital in 2020. Data on age, gender, address, diagnosis were collected. Diagnosis was classified according to urgency. Results: We had 6526 cases with an average of 18 cases per day. The male to female ratio was 1.47:1. Non-urgent cases comprised of 48% of ED visits. The mean age of patients visiting in ED was 34.18+-19.27 years. Foreign body in cornea was the most common diagnosis while mild conjunctivitis was the commonest cause of non-urgent ED visit. The most common age group to visit as true ocular emergency was 21-30 years with 23.20 %. Males were more likely to visit as true ocular emergency than females. Conclusion: younger males are more likely to use Emergency services. More focus should be done in Triaging, Public education and awareness to reduce non-urgent cases in emergency department.
