Background: The objective of the study is to observe frequency of various clinical manifestations of trachoma in rural population. This observational study was conducted at Khalifa Gul Nawaz Teaching Hospital (KGNTH), Bannu, Pakistan from April 2016 to Jan 2017.
Methods: Patients visiting for ocular complaints underwent initial screening that included demographic details and documentation of unaided as well as best corrected visual acuity (BCVA) which was followed by detailed slit lamp examination of anterior segment including eversion of upper lid for assessment of changes in upper tarsal conjunctivas by consultant ophthalmologist. A total of 648 patients who had clinical presentation of trachoma were included in the study. Patients who had other forms of conjunctivitis, trichiasis, entropion, corneal opacification and vascularization due to causes other than trachoma were excluded. Patients were categorized according to age in three groups (Group 1-3) and according to stages of trachoma in five groups (TF, TI, TS, TT and TO).
Results: Six hundred and forty-eight (648) were examined in this cross-sectional survey with a mean age of 14.3+14.2 years. Mean unaided visual acuity and BCVA of the patients was 0.12+.24 and 0.07+0.18 respectively. Groups-1 comprised of 86.7% of the patients and stage TF of trachoma was the most prevalent stage accounting for 70.06% of the patients.
Conclusions: Trachoma is a serious community health problem with various clinical manifestations in different age groups. Awareness and educational programs are required to be conducted in schools and vocational training centres regarding its mode of transmission and control..

Introduction: in Ethiopia, despite implementing decades-long surgery, antibiotics, facial cleanliness, and environmental improvement interventions, commonly known as the SAFE strategies, persistence and recrudescence of trachoma are common. There is limited evidence that explained the reasons. This study assesses factors associated with trachoma in persistently endemic settings.

Neglected tropical diseases (NTDs) encompass a group of approximately 20 diseases prevalent in tropical and subtropical regions, closely associated with poverty, affecting over a billion people in low-income countries. This manuscript aims to explore the ocular manifestations and burden of two significant NTDs, namely Hansen's disease and trachoma while addressing gaps in understanding and management. Hansen's disease, caused by Mycobacterium leprae , has a long history and presents with diverse neurological and ocular manifestations.

Article Synopsis
- Trachoma is an eye disease causing inflammation and potential eyelid scarring, leading to complications like trachomatous trichiasis (TT), and a study was conducted to assess its prevalence in Benin.
- The study involved 23 surveys that measured the occurrence of trachomatous inflammation-follicular (TF) and TT, with a total of 68,613 people examined through various methods of sampling.
- Results showed TF prevalence was below the 5% elimination threshold, but TT prevalence exceeded the 0.2% threshold in nine districts, indicating a need for enhanced case-finding and better access to surgical treatment for TT in Benin.

Reducing the morbidities caused by neglected tropical diseases (NTDs) is a central aim of ongoing disease control programmes. The broad spectrum of pathogens under the umbrella of NTDs lead to a range of negative health outcomes, from malnutrition and anaemia to organ failure, blindness and carcinogenesis. For some NTDs, the most severe clinical manifestations develop over many years of chronic or repeated infection.
