Modified grading system for upper eyelid trachomatous trichiasis.

AIM: This study was conducted to determine the level of inter-observer agreement in the modified grading scheme for trichiasis of the upper eyelid. METHODS: A grading system that covers the entire spectrum of trachomatous trichiasis, extending from the simple to the severe forms, was initially developed by the first and second authors and field-tested. The grading scheme recognizes three levels of severity, based on deviation of the lid margin (TT1, TT2 and TT3); and four anatomical locations indicating where the eyelashes touch the globe in TT1 (nasal, central, temporal, or combined). The grading of trichiasis patients was then conducted on the basis of the modified grading scheme. RESULTS: The inter-observer agreement between the grades of simple trichiasis (TT1) and entropion (TT2) using Cronbach's alpha was 0.84, and the agreement within each sub-grade was 0.86. The weighted Kappa value was 0.68 (95% CI 0.57-0.79) for the main grades and 0.49 (95% CI 0.23-0.79) for the sub-grades. CONCLUSIONS: The inter-observer agreement was very reliable and could easily be attained by all levels of ophthalmic professionals. As the grading follows the natural progression of trichiasis from the simple to the severe forms in relation to the anatomical site involved, it helps to determine the degree of correction and how far to extend the surgical incision.

Accidentally discovered large metallic intra-orbital foreign body.

A 6.2 cm long and 2.7 cm thick metallic foreign body was accidentally found and removed from a 62 years old man. He was sent to a minor operation theater for repair of left lower lid laceration secondary to trauma after a fight. Subsequent investigation, management, patient follow-up and outcome are discussed. Importance of careful history taking, thorough physical examination and proper investigations are stressed.

A randomized clinical trial of the success rates of bilamellar tarsal rotation and tarsotomy for upper eyelid trachomatous trichiasis.

A randomized clinical trial study was conducted to compare the success rates of two surgical methods: Bilamellar Tarsal Rotation (BTR) and Tarsotomy (Transverse Tarsotomy and lid margin Rotation = TTR) for trachomatous trichiasis of the upper lid; where success was defined as no lash/eyeball contact in all positions of gaze, complete lid closure, no under or over correction. The study was conducted at Minellik II Hospital, Addis Ababa. Two hundred fifty six upper eyelids of 153 patients with entropion/trichiasis related to trachoma were enrolled in the two groups. Patients were randomly allocated for the BTR (124) and TTR (132) procedures. Out of these, 237 (92.6%) came for the third month follow-up. One hundred fifteen (48.5%) lids underwent BTR and the remaining 122 (51.5%) underwent TTR. In total, from 141 patients who came for the last follow up, 109 (77.3%) were females. BTR procedure was found to be successful in 25 (86.2%) of the eyelids with minor trichiasis and 74 (86.0%) of those with major trichiasis; the difference between patients who had had minor and major trichiasis (X2 = 0.08, P = 0.772) was not statistically significant. TTR was successful in 39 (95.1%) of the eyelids with minor trichiasis and 68 (84.0%) of those with major trichiasis, again no statistically significant difference was observed for minor and major trichiasis (X2 = 3.15, P = 0.379). There was no statistically significant difference in recurrence between BTR and TTR (X2 = 0.14, P = 0.711). Complications such as lid-notching, pyogenic granuloma, etc. were observed more in BTR than in TTR and this was statistically significant (X2 = 9.54, P = 0.002). In conclusion, the results show that TTR is equally successful in minor and major trichiasis and has fewer complications than BTR at three months of follow-up.
