Phacofragmentation of Posteriorly Dislocated Lens Fragments: Limbal versus Pars Plana Approach.

PURPOSE: To assess intra-operative complications and feasibility of removing crystalline lens fragments from the vitreous cavity through a limbal incision compared to a pars plana approach. DESIGN: Retrospective cohort study. SUBJECTS: 16 eyes underwent phacofragmentation via a limbal approach (Group A) and 9 eyes through a pars plana approach (Group B) at an academic center over a 10-year period. METHODS: We collected pre-operative, intra-operative, and post-operative data. We compared rates of intraoperative complications, including corneal wound burn, iris or capsular damage, retinal tears, and hemorrhage, and recorded post-operative BCVA and IOP measurements at the one-month post-operative appointment. We also compared rates of post-operative complications, including corneal edema, choroidal detachment, or retinal detachment. MAIN OUTCOME MEASURES: Primary outcomes of the study were the rates of intraoperative complications and the feasibility of crystalline lens removal with the limbal approach. We defined the latter outcome as the ability to complete lens removal without switching to the pars plana route. RESULTS: Mean BCVA for group A was 1.6, and for group B was 2.0 (p = .19). There was no significant difference between the two groups in the incidence of intraoperative complications, including corneal wound burn, iris damage, anterior capsular tear, iatrogenic retinal tear, or suprachoroidal hemorrhage (p > .99). There was no significant difference in the incidence of intra-operative vitreous hemorrhage (p = .36). Additionally, there was no significant difference in post-operative corneal edema (p = .27), choroidal detachment (p = .52), or retinal detachment (p > .99). The mean post-operative BCVA was 1.0 in group A and 1.0 in group B (p = .75). We completed all cases in group A using the limbal approach without switching to the pars plana route. CONCLUSION: Phacofragmentation through a limbal incision provides a feasible option for dropped nuclear fragment removal and is not associated with a higher risk of complications than the pars plana route.

Ocular Surface Disease in Glaucoma Patients.

PURPOSE: To review the most recent studies in the literature regarding the ocular surface in glaucoma patients and treatment options aimed to reduce ocular surface disease in this population. METHODS: We performed a literature search in the electronic databases of PubMed CENT RAL, Google Scholar, EMBASE the Register of Controlled Trials, and Ovid MEDLINE using the following terms: "ocular surface", "dry eye", "glaucoma", "selective laser trabeculoplasty", "glaucoma surgery", "preservatives", "preservative free", "ocular surface disease index", "tear break up time", "MMP-9" and "conjunctival hyperemia". RESULTS: Over the last several years, several studies have demonstrated the changes to the ocular surface in the setting of glaucoma, the best tests for markers of dry eye, and how management can be altered to help address ocular surface disease routinely or in preparation for glaucoma surgery. CONCLUSION: Ocular surface disease in the glaucoma patient population is widely recognized. It should be addressed to maximize patient compliance and quality of life.

Endogenous endophthalmitis caused by Staphylococcus capitis.

PURPOSE: To report a rare case of endogenous endophthalmitis caused by Staphylococcus capitis. OBSERVATION: A 34-year-old male patient with a history of gonococcal urethritis and arthritis presented with right endogenous endophthalmitis. Vitreous biopsy culture confirmed Staphylococcus capitis involvement. The patient was treated with pars plana vitrectomy, intravitreal vancomycin, and ceftazidime injections and systemic antibiotics. CONCLUSION AND IMPORTANCE: Staphylococcus capitis-related endogenous endophthalmitis has rarely been reported in the literature. None of the published reports specifically describe its clinical course and management.
