Abstract

Background: Keratomycosis, a fungal corneal infection prevalent in tropical regions, frequently leads to visual impairment and blindness. Liposomal amphotericin B (L-AmB) offers improved efficacy and reduced toxicity compared to conventional amphotericin B deoxycholate and represents a promising option for topical ophthalmic use. Objective: To evaluate and compare the therapeutic efficacy of L-AmB eye drops at 0.15% and 0.5% concentrations in experimental Aspergillus keratomycosis in New Zealand White rabbits. Methods: Four rabbits received midstromal corneal inoculation with a mixed suspension of Aspergillus flavus, A. fumigatus, A. niger, and A. terreus (2 x 10⁴ CFU/0.05 mL). L-AmB eye drops were applied hourly from day 8 post-inoculation until corneal cultures became negative. Antifungal susceptibility was assessed by disc diffusion. Clinical response was monitored by slit lamp examination using a modified scoring system. Results: Negative corneal cultures were achieved in all treated eyes within 10 to 18 days (mean 15 days, L-AmB 0.15%) and 11 to 15 days (mean 14 days, L-AmB 0.5%). No toxic effects were observed. Complete corneal transparency without cicatrix was achieved in one eye treated with L-AmB 0.15%. Conclusion: Both concentrations were effective and safe. Liposomal AmB 0.15% appears as efficacious as 0.5% for experimental Aspergillus keratomycosis. Clinical studies in humans are warranted.

Abstract

Background Indonesia is a tropical country exposed to ultraviolet (UV) rays year-round, particularly in Central Sulawesi Province, which lies on the equator. Tojo Una Una Regency is located in this province, and the majority of its residents work as fishermen, who are frequently exposed to UV radiation, a risk factor for pterygium and dry eye. This profession has the highest incidence of pterygium, reaching 15.8%. This study will analyze the relationship between pterygium and dry eye. Methods The study design was cross-sectional with consecutive non-random sampling. A questionnaire was used to assess characteristics. Pterygium was diagnosed through an anterior segment examination by a general practitioner, followed by a double-blind ophthalmologist to assess the degree, location, and whether the pterygium was single or double-headed. The degree and diagnosis of dry eye were confirmed using the OSDI questionnaire. Results The study involved 400 respondents, and the prevalence of pterygium reached 85.25%, with cases predominantly bilateral (66.5%), single-headed (70.25%), female (72.75%), 26-45 age group (49.25%), and those working outdoors (77%). DES cases were found in 54.25%, with the majority being severe DES. A chi-square test showed a relationship between dry eye and pterygium (p<0.001). Conclusions There was a significant relationship between DES severity and pterygium incidence (p<0.001).

Abstract

Hantavirus is a zoonotic virus belonging to the genus Orthohantavirus which causes emerging infectious diseases with high levels of morbidity and mortality. This virus is transmitted primarily through exposure to aerosols containing urine, feces, or saliva of infected rodents. Climate change, urbanization, changes in land use, and increasing interactions between humans and reservoirs contribute to the increasing risk of hantavirus transmission in various regions, including Indonesia. Hantaviruses are divided into Old World hantaviruses which cause Hemorrhagic Fever with Renal Syndrome (HFRS) and New World hantaviruses which cause Hantavirus Cardiopulmonary Syndrome (HCPS). Clinical manifestations vary from acute fever to renal or respiratory failure with a fatality rate that can reach 30–50% in HCPS. Diagnosis is made through a combination of history, clinical manifestations, serological examination, and molecular detection using RT-PCR. Until now, there is no specific antiviral or vaccine available that is widely used, so management still focuses on supportive therapy. In Indonesia, hantavirus infections are thought to still be underdiagnosed and underreported, even though serological and molecular evidence shows the circulation of the virus in humans and rodents. Hantavirus is an emerging zoonotic disease that has the potential to become a threat to public health. Increasing clinical awareness, strengthening surveillance, early detection, rodent control, and implementing the One Health approach are important strategies to reduce the risk of disease transmission and impact, especially in developing countries like Indonesia.
