Scleral buckling (SB) remains an important technique to master for those interested in treating rhegmatogenous retinal detachment (RRD). Several ways to repair RRD include pneumatic retinopexy (PR), pars plana vitrectomy (PPV), SB or a combination of these. There is a growing worldwide trend that favors PPV as the preferred method for retinal reattachment of primary uncomplicated RRD. Reimbursement issues, operating room access, and technological advances in PPV that improve retinal visualization and less exposure to SB during fellowship training may explain this trend. As the number of SB cases decreases over time, there is a risk that SB becomes a dying art and surgeons in training may not be trained in SB. SB is preferred in eyes with no posterior vitreous detachment and retinal dialysis. SB with minimal gas vitrectomy may be indicated for eyes with inferior pathology. Non-contact wide-angled visualization with chandelier assisted SB may be well suited for teaching new generations of aspiring vitreoretinal surgeons. Its functional and anatomic results compare favorably with conventional SB for primary uncomplicated primary RRD. The main advantage of this technique is the improved visualization even through small pupils. Better visualization ensures treatment of all breaks while avoiding complications during drainage of subretinal fluid and a safer placement of intrascleral sutures for scleral fixation of the buckling element. Recordings of the procedure are easily performed, allowing the surgeons involved to review the case and learn from it. The main disadvantage is the cost involved with the chandelier and the need to have a microscope or a 3D system with a wide angle viewing system. Photoreceptor re-alignment following retinal re-attachment is an important determinant of the post-operative functional outcomes. Different methods of retinal re-attachment apparently result in different degrees of photoreceptor re-alignment. SB may hold an advantage over PPV in this regard.

Comparar el período de latencia del reflejo patelar con o sin la maniobra de Jendrassik. Ocho sujetos, sanos; con un promedio de 20 años de edad. El estudio será realizado en la pierna dominante del sujeto, en el laboratorio de fisiología del edificio Versalio Guzmán de la Universidad de Ciencias Médicas el 7 de marzo 2018. Se midió el tiempo de latencia del reflejo patelar con o sin la maniobra de Jendrassik. De los ocho sujetos se obtuvo una latencia del reflejo patelar sin la aplicación de la maniobra de Jendrassik es de 33.45 ms, mientras que aplicando la maniobra de Jendrassik se obtuvo una disminución de latencia de 31,28 ms. El estudio muestra cambios producidos por aplicación de la maniobra, sin embargo, no se logró presentar una disminución significativa en la latencia del reflejo patelar.
