Expanding a photographic grading system for trachomatous scarring.

BACKGROUND: The purpose was to assess an expansion of a previously published photographic four-step severity grading scale for trachomatous scarring (TS). METHODS: Images of everted eyelids of adult women in Tanzania were graded for the presence and severity of TS. The previous S3 grade was subdivided into two categories: S3A, one-third to <50% of the upper eyelid conjunctiva scarred; and S3B, 50% to <90%. The reliability and ease of use were evaluated. This new categorisation was then applied to images taken of the same women 5 y prior to evaluate whether it could help detect previously undetected progression. RESULTS: In total, 142 eyes at baseline and 418 eyes at follow-up after 5 y were graded as S3. Interobserver agreement using the expanded scarring grading scale was a kappa of 0.86. At baseline, 51 (35.9%) eyes were S3A and 91 (64.1%) were S3B. At follow-up after 5 y, 36.6% of the eyes that were previously documented as not having progressed were now detected as having progressed from S3A to S3B. S3B images were more likely to progress to S4 compared with S3A (OR 4.6, 95% CI 2.1 to 9.9). CONCLUSIONS: Adding S3A and S3B is reliable and detects more scarring progression. It will be beneficial for future studies analysing TS in photographs.

Perceptions of ophthalmologists on the impact of trachoma in Egypt: a mixed-methods, nationwide survey.

PURPOSE: Understanding the perception and practices of ophthalmologists for trachoma is important to develop interventions aimed at disease elimination in Egypt. The survey investigated: (1) the views and practice patterns of Egyptian ophthalmologists for trachoma and (2) the influence of geographic location, setting, and years of practice on ophthalmologists' perceptions. METHODS: A questionnaire sent to ophthalmologists currently working in Egypt collected information on: (1) demographics, (2) caseload and practice patterns for trachoma, (3) 13 Likert scale questions regarding the current state of trachoma, and (4) two open-ended written response questions. RESULTS: Of the 500 recipients, 194 ophthalmologists participated. 98% of the respondents reported seeing trachoma patients in their practice. 28.8% agreed that trachoma is currently an active health problem in Egypt, with ophthalmologists in public practice having significantly higher agreement scores compared to private practitioners (p = 0.030). Rural ophthalmologists were significantly more likely to agree that a targeted trachoma control program is needed in their location of practice compared to their urban counterparts (p < 0.001). Open-ended questions revealed recurrent themes, including the rural distribution of trachoma patients and the high volume of patients with corneal opacity. CONCLUSION: Ophthalmologists' experiences with trachoma in Egypt differed based on practice setting, years in practice, and location, and the overall perception of the impact of the disease remains low. However, there was widespread agreement that trachoma is present in communities across the country. Practitioners in rural areas and in the public sector shared a disproportionate burden of the trachoma caseload. The perspectives of such ophthalmologists must be emphasized in decision-making related to trachoma interventions.
