Validity of ophthalmology surgical competency assessment rubric for strabismus surgery in resident training.

The Accreditation Council for Graduate Medical Education (ACGME) requires US residency programs to assess ophthalmology residents for competency in 6 core areas. Ophthalmic surgical skills are currently part of the ACGME "Patient Care" competency, although some have advocated for a seventh competency, "Surgical Skills." The Ophthalmology Surgical Competency Assessment Rubric for Strabismus Surgery in Resident Training ( OSCAR: Strabismus) tool was designed to aid in the assessment of surgical skills using procedure specific behavioral anchors. The present study evaluated inter-rater agreement of the OSCAR: Strabismus tool in the assessment of resident performance. OSCAR: Strabismus evaluations of resident surgical strabismus cases were performed by a multinational group of faculty strabismus surgeons. Cronbach α statistical analysis of the completed evaluations revealed high inter-rater agreement, indicating the OSCAR: Strabismus is a reliable tool to facilitate assessment of resident strabismus surgical skills.

The ophthalmology surgical competency assessment rubric for strabismus surgery.

PURPOSE: To produce an internationally valid tool to assess skill in performing strabismus surgery. METHODS: A panel of 7 content experts adapted a previously published tool for assessing phacoemulsification by using a modified Dreyfus scale of skill acquisition and providing behavioral descriptors for each level of skill in each category. The tools were then reviewed by 12 international content experts for their constructive comments. The main outcome measure was a consensus of the experts on the final rubric. RESULTS: Experts' comments were incorporated, establishing face and content validity. CONCLUSIONS: The tool (Ophthalmology Surgical Competency Assessment Rubric for Strabismus Surgery (ICO-OSCAR: strabismus) has face and content validity. It can be used globally to assess strabismus surgical skill. Reliability and predictive validity are yet to be determined.

Perfluorocarbon liquid vitreous delamination and wide-angle viewing system in the management of complicated diabetic retinal detachment.

PURPOSE: The authors used perfluorocarbon liquid (PFCL) and a wide-angle viewing system (WAVS) to evaluate their efficacy on tractional and combined tractional/rhegmatogenous retinal detachment (RD) secondary to proliferative diabetic retinopathy (PDR). METHODS: In a prospective, noncomparative, interventional study, 76 consecutive cases of severe PDR with tractional and combined tractional/rhegmatogenous RD were submitted to vitrectomy en bloc excision technique using a WAVS and delamination with PFCL between July 1999 and December 2003. None of the patients had had previous retinal photocoagulation treatment. Preoperative characteristics, intraoperative findings, and procedures as well as postoperative results were recorded. Main outcome measures included visual acuity (VA) and rates of retinal reattachment and complications. RESULTS: After 1 to 4 years of follow-up (mean 34.3 months), the number of patients changed from 3 (3.95%) to 11 patients (14.47%) in the > or =20/40 VA range, from 12 (15.79%) to 7 (9.21%) in the 20/50 to 20/200 group, and from 61 (80.26%) to 58 (76.31%) in the < or =20/400 group, preoperatively and postoperatively, respectively. The mean final VA improved from 1.2 log-MAR before surgery to 0.89 after vitrectomy (p=0.001). This modified technique resulted in less bleeding during surgery, a better identification of intraocular structures, faster retinal reattachment, subretinal fluid reabsorption, and easier dissection of fibrovascular membranes, among other benefits. CONCLUSIONS: PFCL and WAVS appear to reduce intraoperative complication rates in the management of complicated cases of tractional and combined tractional/rhegmatogenous RD secondary to PDR. Retinal reattachment and functional vision rates improved after this technique.

Strabismus following posterior segment surgery.

Persistent diplopia following posterior segment surgery is not uncommon. There are several causes of postoperative strabismus, some of which are preventable. Knowledge of the possible causes, proper evaluation, and appropriate treatment can eliminate or at least reduce the morbidity from this unwelcome postoperative surprise.

Complete bilateral vitreous detachment after LASIK retreatment.

We describe a case of a 47-year-old woman who underwent bilateral laser in situ keratomileusis (LASIK) for the correction of myopia and astigmatism. Two months later a residual refractive error was present in both eyes. LASIK retreatment was decided and performed the following day. Twenty-four hours after the procedure, the patient reported myodesopsia in both eyes. Funduscopic examination revealed a complete bilateral posterior vitreous detachment confirmed by kinetic ultrasound. Visual disturbance in both eyes continued to be present after 10 months of follow-up. Sudden changes in intraocular pressure related to suction ring use might be the cause of posterior vitreous detachment in this patient.
