Scleral Dellen after Routine Uneventful Pterygium Surgery.

Occurrence of Scleral Dellen is rare but serious complication with stromalinflammation with tissue loss and scarring. Scleral dellen results from localdehydration & thinning of scleral tissues with exposure of underlying uvea leading toblueish colour. Occular surgical causes of occurrence of scleral dellen are strabismussurgery, pterygium excision (with or without use of adjunctive treatment like betaradiation, conjunctival autograft and Mitomycin C), cataract extraction.1,2 Patientscomplain of foreign body sensation & mild discomfort. Treatment consists ofreduction or elimination of contributing perilimbal elevation, & rapid rehydrationwith artificial tears, eye ointment and patching3. If treated properly dellen usuallyresolves completely without permanent sequelae. We report a case of severe scleraldellen that occurred 14 days after the uneventful surgical excision of primarypterygium without adjuvant therapy. We describe a patient with scleral dellen, whichoccurred after an uneventful pterygium excision without adjunctive therapy.

ViVan Ratio for Maxillomandibular Tooth Material Discrepancy.

According to the guidelines of the American and Indian Boards of Orthodontics, it is essential to include second molars, while managing an orthodontic case. Therefore, the present study was planned to determine maxilla-mandibular tooth material discrepancy.METHODSThe study sample consisted of study casts of 300 subjects in the age range of 18-30 years. Samples having a full complement of teeth with Angle’s Class I molar and canine relationships, good intercuspation, normal overjet and overbite and minimal crowding and spacing were included in the study. Tooth dimensions were measured using digital vernier caliper (accurate to 0.01 mm) and overall ratio was calculated. The data was statistically analysed for range, mean, standard deviation and coefficient of variation.RESULTSViVan ratio was found to be 90.79 with standard deviation of 3.13, variance of 9.81 and range was 83.55 - 95.82.CONCLUSIONSIdeal tooth proportions play an important role in achieving good occlusion at the end of orthodontic treatment. The ViVan ratio obtained in the study included second molars and this would benefit the orthodontist in proper treatment planning. This ratio will add importance for improved results at the finish of orthodontic treatment.
